Chapter Text

______



As time passes, Tzuyu can say that she's growing genuinely fond of her alpha roommate, Sana. Why? She's not really sure but she's content with how things are now. They've become good friends, more than that, Sana is the ideal roommate, but most importantly the alpha is the perfect cycle mate. 

 

Tzuyu is naturally shy. She refrains herself from speaking her truth because she doesn't like the attention that comes with it. Sana on the other hand coaxes her truth and gives her enough space to make her comfortable to spill out her reason, like when Tzuyu says she wants to try stop eating beef, Sana doesn't judge her for it, instead she says, 'I saw this vegan place near campus and they sell tacos. Can we try that this weekend?' 

 

Most of Tzuyu's friends would react differently, they'd ask, 'Why?' in a confused, you're-so-ridiculous-kind-of-way, or worse yet, Tzuyu's personal pick, 'are you one of those alt left protect-the-planet girls?' and they'd ask with judgment, one eyebrow raised, a little condescending smile on their face. 

 

The truth is Tzuyu likes animals. Period. It’s that simple. She doesn't have any other reason. Cows are cute, like how dogs and cats are cute and she doesn't feel like eating them— if she can help it. She doesn't mind eating beef once in a while but she wants to avoid consuming them if she can. 

 

Does Sana judge her for it? Absolutely not. It's like Sana always knows exactly what to say to Tzuyu, how to say it, and when to say it. Tzuyu feels so understood that it becomes her habit to go to Sana when she feels frustrated about stuff. Mostly communication related stuff. 

 

They never fight, not once. Tzuyu has never had communication problems with Sana, that is until she accidentally reads her text, sent by one of Sana's best friends.

 

Myoui Mina. The professor's daughter. A ridiculously pretty girl, a well mannered, tea drinking, soft spoken omega.

 

It happened this evening. 

 

Just earlier Sana came home all hot and sweaty. It was the humid summer weather. Sana hates summer. Sana said she can't stand the heat. But Tzuyu thinks the alpha looks absolutely attractive when she's all drenched in sweat, her white shirt opened three buttons down, revealing a plane of skin and curves. 

 

While Sana walked toward her Tzuyu couldn't help herself but to steal some appreciating looks, staring at the necklace hanging on the alpha's collarbone. It's their friendship necklace, Sana bought them matching ones a few weeks ago. Tzuyu would wear hers when she's going out. 

 

And it seemed like Sana knew that she was being stared at. She didn't immediately go to her room like she always does. Instead she put her bags beside Tzuyu on the dining chair next to her and threw her phone on the table before she gave her a smile. 

 

The smell of rain, Sana's scent, enveloped Tzuyu as she leaned close. She said 'what are you up to?' And Tzuyu answered with a smile. 'Just watching stuff,' she said. Then she pushed Sana gently away from her and said, 'get changed,' because she wanted to hug the alpha but not when she was still sweaty. 

 

So Sana went inside her room without protest and that was when her phone lit up. The notification popped up with the full messages displayed on the screen. 

 

Mina chan : did you really leave?

Mina chan : why didn't you say goodbye?

Mina chan : is it an emergency? 

Mina chan : or are you on a rut? 👀 it's around this time right? I remember your schedule.

Mina chan : let me know if you need help

 

When Sana skipped out of her room to join Tzuyu in the dining room she didn't immediately notice the change in the atmosphere until she sat down beside her roommate and saw the deep frown etched in the omega's face. 

 

"What's wrong?" Sana leaned in, obviously worried. 

 

That's Sana for you. She can read people's moods. It's her gift. Yet Tzuyu had nothing to say, too shocked by what she saw. Hundreds of questions came to her at once but she didn't know how to voice them out properly. So she said—"Nothing. Uh, I'm tired I think I need to rest," and escaped to her room.

 

Now she finds herself laying face down on the bed. Questions swarm her mind. What did Mina imply when she said— 'I remember your schedule.' Or 'let me know if you need help.’ Were they cycle partners? Or are they still are? The idea that Sana is sleeping with other people without telling her is bothering Tzuyu so much that her head starts aching. 

 

Shouldn't Sana tell her if she has another arrangement with another omega? She should have! It's only ethical. How can Tzuyu not know that Sana is also tending to other omegas? 

 

By the time the clock hits 9pm, Tzuyu is still stuck in her room. Still deep in her thoughts. The longer she stays there the more confused she is. It's like she's stuck in a spiral of self doubt and negativity. She's upset but she doesn't really know why. In fact  she's so upset that she feels like crying but she holds it off, fearing that she's being too dramatic. 

 

Perhaps she needs sleep. Rest her mind. She's overthinking everything. Yeah that's must be it. Tzuyu rolls around and wraps herself in a blanket, making herself comfortable. She's about to close her eyes when Sana suddenly knocks on her door. 

 

"Hey," Sana calls out from the other side. "Can I come in?"

 

For a split second Tzuyu is tempted to ignore the call. She buries her face in a pillow, pressing it tightly against her nose, pouring her frustration onto it. When she's starting to get out of breath she sits up and calls back. "Come in," she says.

 

Sana peeks in with a sheepish smile upon her face. "Were you sleeping? Did I wake you?" 

 

"I wasn't. It's okay." Tzuyu sighs. "What's up?" 

 

Tzuyu guesses that the clipped tone of her voice doesn't go unnoticed by Sana. 

 

"Alright. What's wrong, really?"

 

"I just need some time alone," Tzuyu says. 

 

"Did something happen? Did I do something wrong? You seem to be.. a little mad at me." 

 

"Can we not do this now?"

 

"Tzuyu," sighs Sana. "If I did something wrong, or something that you don't like, you should definitely tell me."

 

"I don't know, Unnie, is there something you haven't told me?"

 

"What are you talking about?" 

 

"Can I have more than one cycle mates?"

 

Sana frowns. "Huh?" The alpha crosses her arms. Sana looks so bothered by the question. She bristles and tightens her jaws but when she speaks again she sounds almost gentle. "Why? Did you meet someone?" 

 

"You have more than one cycle mates. Why can't I?"

 

Incredulous, Sana shakes her head. She steps forward and unfolds her arms. 

 

"I don't have someone else. What— how do you even come to that conclusion?"

 

With the truth already half spilled, Tzuyu knows that she has no choice but to say everything that she wants to say. "I saw Mina unnie's texts. Sorry I didn't mean to," she says, her voice turns quieter towards the end of her sentence. "Just tell me the truth, are you helping her with her cycle?" 

 

The frown in Sana's face disappears instantly. Sana exhales, seemingly glad. "We were cycle partners, yes, before this arrangement." Sana gestures towards Tzuyu and herself. Then she shrugs.  "Mina and I are just regular friends now." 

 

There's a part of Tzuyu that cheers up at the thought. A weight is lifted out of her chest as she processes Sana's answer. However there's a part in her heart that still feels heavy. "Is there any other omega now?" 

 

"No one," Sana says, seemingly a little bashful by the confession. "Only you." 

 

"I see," Tzuyu says. Weird as it is, she believes her roommate. But now she feels embarrassed. Embarrassed by her outrage. Embarrassed that she's taking things out at Sana without really understanding the full situation. "If you're gonna help someone else you gotta tell me, Unnie." 

 

"You don't have to worry about that," says Sana kindly. "I don't need anyone else.” 

 

Tzuyu can’t help but smile at that.  

 

Seeing the change of her roommate’s expression, Sana smiles back. “Are we good now? Can I hug you?" 

 

And just like that Tzuyu decides that she's no longer mad at her roommate. With a nod, Tzuyu gives Sana the permission to her bed and the alpha skips toward her almost instantly, tackling her until she's lying flat on her back.

 

"I'm sorry I made you upset," Sana says, lips pressed against her hair. Her voice is muffled but Tzuyu can hear her just clearly. 

 

"I'm sorry too," says Tzuyu as she wraps her arms around the alpha's slender frame.

 

They do this sometimes, hugging each other, like when Tzuyu went back to Taiwan for a week and they hadn't seen and talked to each other for a while or when Tzuyu felt bad about something; a bad grade, a failed class. Today is different though, today Sana is not trying to comfort her, instead she seeks Tzuyu for comfort. 

 

They stay like that for a while, wrapped around each other until Sana puts more weight on top of her and Tzuyu has to roll them over, complaining all the while. "You're heavy," she says jokingly. 

 

"Be my pillow," Sana insists, reclaiming her spot on top of Tzuyu's chest. Tzuyu tries to jokingly push Sana off of her but she does it so weakly that the alpha safely assumes that Tzuyu doesn't really want her to go. "Just five minutes," she whines as she pushes the omega down. But that five minutes turn into ten, and that ten minutes turn into half an hour, and by then Sana is already fast asleep. 

 

Tzuyu assumes she falls asleep as well some time during the night because the next time she opens her eyes Sana is spooning her and she doesn't remember when and how they've changed position. What wakes her up is the alpha's hand which has traveled inside her shirt, loosely cupping her breast. Sana's thumb is innocently pressing against her nipple. The slight pressure sends pleasant tingles to her spine. 

 

Okay, well, maybe not so innocently after all. 

 

She scoffs. Sana does this sometimes when they cuddle but she always does it in her sleep. The first few times were quite surprising but now after experiencing it for the nth time she doesn't mind at all. She even thinks that it's quite endearing albeit how unappropriate it actually is. But that's how alphas are; possessive, even when they're asleep. 

 

However Sana’s possessiveness is not the kind of possessiveness that suffocates her. It’s not the controlling kind and it’s definitely not even the jealous kind.  Sana becomes physically possessive when she's in the rut and when she's pressed against Tzuyu like this, as if she's craving the omega's skin. In her rut, when they're not having sex, Sana will orbit around her. She'll place a hand around Tzuyu's waist, or press her leg against Tzuyu's, or play with the omega's hair, anything, as long as she can touch her. 

 

It's a wonder how she can endure the amount of physical touch. Maybe she should blame it all on her omega instinct since it gives her the same insatiable craving. She wants Sana to touch her. She wants her fingers in her hair. She wants the alpha's cheek on her chest. It feels so good cuddling with her roommate after a long day at school. It feels so nice to lay her head on Sana’s lap when they’re watching House of Dragon together every Monday morning. She wants Sana. Period

 

For some reason that she can't quite comprehend, she'll feel incomplete whenever they part, however this craving only happens when she's in heat. She doesn’t feel it as much when she’s not in her heat. 

 

"Unnie?" Tzuyu turns her head though she's still tired and tries to peek but unfortunately she can't see anything in the dark. She can only make out shadows. Sana doesn't answer, seemingly fast asleep. Her chest falls and rises slowly, pressing and retreating against Tzuyu as she continues to dream, oblivious to her roommate's call. 

 

The alpha smells a little different than how she normally is, Sana’s scent is pleasantly alluring but also comforting at the same time, like misty rain and fresh morning dew. Tzuyu recognizes the scent, she's smelled it quite a few times before to know that Sana is dangerously close to her rut schedule.

 

Still sleepy, she shifts to a more comfortable position, instinctively backing up into Sana's embrace, seeking warmth, wanting to smell more of the scent that the alpha oozes, but that's when she feels it; Sana's semi, though concealed by her shorts, is poking right at her butt. 

 

Honestly, she wants to laugh but at the same time she feels so proud of herself, the effect that she has on the alpha, even in her sleep, is so powerful. The fact that she's being so desired is giving her a primal shot of confidence. With her eyes now closed Tzuyu reaches behind her and cups Sana's dick gently, mapping the shape with her palm slowly, feeling it unmistakably grows bigger and harder in her hand  

 

She's not trying to do anything else, she's just feeling Sana up through her flimsy shorts. Between sleepy daze and fogs of dream, Tzuyu continues to stroke the alpha with feather light touches, teasing the head, feeling the firmness, that is until Sana moves lazily against her. 

 

She’s waking up— Tzuyu thinks. And just as suddenly the alpha' sweet delicious scent envelops her completely. 

 

It's sweet. Sana smells sweet. Tzuyu barely has the consciousness to register what happens next but she feels the hand cupping her breast finally moves, fingers tweaking her nipple languidly, pinching, teasing, bringing it into stiffness. Sana presses feather-like kisses on her shoulder. Her lips are soft and warm. "Tzuyu, sweetie, are you awake?"

 

Tzuyu answers with a raspy hum. She shivers when Sana begins to knead her breast with more passion. Spikes of pleasure travel to her spine. Tzuyu is slowly getting turned on but she's so tired that she can barely acknowledge the building ache between her legs. 

 

"My rut," Sana whispers to her hair. "But if you're too tired I'm-" 

 

"Use me," Tzuyu blurts out before Sana can leave. She opens one eye and shadows the alpha's hand kneading her breast. "Don't stop, even if I fall asleep. I want it." 

 

"But-" 

 

"Don't go," says Tzuyu. The alpha can't go. She won't allow it. And she knows Sana wants her. The only thing stopping Sana from taking her is her morale and thus Tzuyu gives her the full permission now. "I need you, Unnie."

 

"Are you sure?" Sana climbs on top of her, slotting her clothed hardness against Tzuyu's crotch. Before Tzuyu can answer, Sana is already pulling Tzuyu's shirt up, revealing her heaving breasts. 

 

Tzuyu whimpers as Sana dives down, taking a nipple between her lips, and starts sucking softly. 

 

Her own hands fly out and land on the alpha's head, stroking it, letting the girl on top of her know that she wants it just as much. "Yes, Unnie," she says. 

 

So Sana enjoys her, touching her all over to satisfy her own most primal need. Between dreams Tzuyu wakes from time to time, feeling Sana's lips travel from her breasts to her pelvis, taking off her shorts and panties, one leg at the time, sucking her clit while fingering her at the same time, determined to bring her to orgasm, even when Tzuyu is barely awake. 

 

It's useless to fight the pleasure, Tzuyu allows herself to fall into a release faster than she normally is, having no control over her body as Sana continues to use her without resistance. 

 

The second time she comes, Tzuyu wakes up with a violent tremor as the orgasm jolts her awake. As she opens her eyes, she realizes that Sana is still toying with her clit while lapping at her nipple. It feels so good. It feels amazing. Tzuyu cries out. She loves the way Sana's sinful tongue dances around her nipple. She loves the way Sana's long, slender fingers playing with her clit, moving in tight, circular motion. 

 

"Feel good?" Sana whispers against her skin, realizing that Tzuyu is slowly waking up. Lust dripping in her voice. She's wiggling her fingers inside the omega's throbbing cunt while Tzuyu is trying to ride off her climax. Sana curls her fingers once she's reaching knuckles deep, pumping them in and out, making sure she’s hitting all the right spots. "Mm, look at you so wet. You're so fucking wet." 

 

Next thing Tzuyu knows she's being flipped over. A pillow is being slipped under her hips, propping her up into position. Her clothes— Tzuyu belatedly notices, are gone now, thrown to the side. She’s fully bare. Exposed. All for Sana’s full enjoyment.

 

Still sensitive from her second orgasm, Tzuyu jumps slightly as the soft fabric of Sana's shirt brushes against her naked skin, followed closely by the alpha's warmth as she completely drapes herself on top of the naked omega. 

 

Tzuyu weakly spreads her legs, accommodating Sana's hardness to slide between her drenched folds. It kisses her clit then it slides back to her entrance. "Unnie, I can't stop sha-" 

 

"Stay still, don't move," Sana says as she pushes her cock inside in one firm stroke, until she's balls deep inside Tzuyu's welcoming, grasping cunt. The searing pleasure is almost too much to take. Tzuyu lets out a broken whimper, feeling Sana's fat girth stretching out her pussy. It feels so good that her eyes roll to the back of her head.

 

 The alpha groans as she rut, feeling the tight walls throb and squeeze around her girth greedily. So pleased. So drunk in lust. "You're shaking. Do you like being used that much?" 

 

"Yes," Tzuyu answers truthfully. Blood rushes to her cheeks as she makes her confession. It's hard to admit but she loves being used by Sana. Her omega instinct tells her to submit to the alpha wishes, to satisfy her, but Tzuyu begrudgingly knows that there's something more than that, something deeper than her animalistic need. "Feels so good," she whines into the pillow.

 

"I love it here, Tzuyu," Sana says as she hits Tzuyu's g-spot. Her hands are now grabbing both of Tzuyu's wrists, holding them so tightly, planting them on the sides of their heads. Tzuyu is trapped. She won't be able to escape even if she wants to. 

 

"You feel that? That's my favorite spot," Sana whispers in her ear. Tzuyu nods weakly. Involuntary moans escapes her lips while Sana's cock drags in and out of her. The alpha continues to fill the omega so deliciously deep, pumping in quick, rapid thrusts. The lewd sounds of their hips slapping against each other is filling up the bedroom. 

 

"Your pussy feels so good. So fucking good," Sana says breathlessly between thrusts, emphasizing each word by slamming her hips down. “Fuck, I need you to cum around me. Wanna feel your pussy cumming on my cock.”

 

"Come on me too," Tzuyu whines. For some reason that she can’t quite comprehend, a slight pang strikes her as the words escape her mouth. There's something missing. Something crucial. She doesn't know what it is. It's like a blanket is being draped over her muddled brain. She tries not to think about it too much but then she feels it, the swell of Sana's knot. It's kissing her entrance, slipping in and out of her as the alpha keeps fucking her into oblivion. 

 

It takes several blissful pumps of Sana’s rapidly swelling knot before she comes into a realization. She knows what’s been bothering her; knot, she desperately wants to be knotted— not only that, she desperately wants to be knotted by Sana

 

Once she recognizes it, the desire becomes greater. She imagines Sana pushing that knot inside of her, wriggling it inside her quivery walls, until they’re stuck against one another, limbs intertwined, lost in pleasure together. She wants Sana to shoot it all inside her, until all Tzuyu can feel is warmth blossoming in her lower tummy, filling her up to the brim, not letting her escape— putting  a baby inside her

 

The last thought seizes her whole body in an instant. It comes to her seemingly out of nowhere, but then the thought triggers her to cum. Her legs quake as the orgasm sets her nerves ablaze with bliss. Not only that, as she trashes under Sana’s relentless pounding, a nagging pressure builds up in her lower tummy. An urge overtakes her as she squirms around. It’s too much. Too intense. She can't hold it in. 

 

Fuck, Tzuyu,” Sana laughs as the omega helplessy squirts around her, ruining the sheet under them. “That’s a good girl, fuck, baby,” Sana keeps praising her as she keeps slamming into her, her knot now swelling so much that it almost impossible for her to pull out, much to Tzuyu's delight, but then somehow Sana manages to pull out at the last minute, before her knot is completely swallowed by the tight ring of the omega's slippery cunt. Once she slides out, Sana gasps as her cock twitches and tenses, expelling thick ropes of cum between the omega’s thighs, ruining the sheet even more. 

 

Tzuyu can barely hum her approval when Sana lands kisses along the length of her neck, praising her gratefully — "You feel so good. What a good girl. You’re taking my cock so well."

 

Though Tzuyu’s heart sings and swells at the praises, she still can’t get over the fact that she wanted— no, needed the knot. The hollowness appears in her chest, creating a void within her. She brushes it off, thinking that it’s just her omega hormones acting out. 

 

No. Tzuyu doesn’t want to have Sana’s kids. No. She can’t be. She’s not that attached to the alpha right? It’s not like she’s in love with Sana or anything, right?

 

Right?

 

————————-




 

 

 

 

 

 

"Where were you two this morning?" 

 

Nayeon hops towards them at the cafeteria. Her tone implies that she actually knows the truth. Tzuyu blushes. There's no way Nayeon unnie knew that Sana was still in her rut this morning. No way that Nayeon knew that Sana was fucking Tzuyu all day yesterday and this morning too. They were late because Sana couldn't keep her hands off of Tzuyu until an hour ago. 

 

Sana jumps in between Nayeon and Tzuyu, putting her arm around the older girl's shoulder. 

 

"Why are you so nosy?" She giggles, letting Nayeon know that she's just messing around. "Don't you have other friends?"

 

Nayeon rolls her eyes. "Fine. Don't tell me. Now, where are we sitting?" 

 

A quick sweep over the cafeteria and Nayeon immediately lead them to where Mina and Momo are sitting in the circular table. Mina looks up at them as Nayeon sits beside her. Sana takes a seat on the opposite side beside Momo, meanwhile Tzuyu.. well Tzuyu has to take the only seat available beside Mina.

 

"Oh," Mina says, smiling at Tzuyu, pausing mid bite. "I thought you're Sana for a second, you smell like her."

 

To say that Tzuyu is stunned is an understatement. "I do? Oh wow, well." She nods awkwardly. Warmth fills her cheeks. Mina must be right considering what happened just an hour ago. "Last time I checked I'm still Tzuyu," she says hesitantly. 

 

Nayeon laughs so hard that she almost falls out of her chair. Meanwhile Sana and Momo send meaningful looks to each other. Sana breaks eye contact first, bashful. 

 

"Must be nice," Nayeon says as she slurps her iced coffee. 

 

"I'm jealous. I miss it," Mina says as she pretends to pout. 

 

"Yeah, okay, can we not talk about it?" Sana whines. "God, way to make me feel awkward."

 

Everyone laughs, including Tzuyu. Sana's friends are just teasing them. It's nothing but good natured banter at lunch time. However, although Tzuyu is laughing along with the girls, she secretly feels bothered by it, especially with Mina's harmless jab- "I'm jealous. I miss it." 

 

Miss what? Tzuyu scoffs inwardly when she's at class. Okay, sure, Mina was Sana's cycle mate. Apparently everyone knew except for Tzuyu. Images of Mina being intimate with Sana are swirling in her mind. Naked skin pressing against each other. Sana on top of Mina, doing the things that Sana did to Tzuyu. 

 

Tzuyu hides her face as she pouts. No. Why is she imagining these things? She doesn’t want to think about it. She should focus on her studies. 

 

The more she tries to stop the more vivid the images are for her. Have Sana unnie praised Mina like she praised her? Were they as passionate as they are? 

 

Amidst the barrage of questions, one stands out the most. If Mina unnie was Sana unnie’s cycle mate does that mean she’s taken the.. knot? Tzuyu bites her lip, horrified by her own thoughts. She can’t stop thinking these thoughts, no matter how wild they are. 

 

The last question bothers her so. The thought stays with her after the classes are over, it stays with her while she’s on the bus home. It’s there in the back of her mind when she’s stepping inside her apartment. 

 

Earlier Sana told her that she’ll be back a bit late—to finish a paper which will be due this week. Tzuyu feels an irrational fear overtakes her so she fishes out her phone and calls her roommate. 

 

“Hi!” Sana answers cheerfully. Tzuyu can hear her smiling. “What’s up?”

 

“Are you going to be home before 10?”

 

“Depends,” Sana says, sounding perplexed. In the background Tzuyu can hear Nayeon and Momo fighting over something. ‘No, unnie I told you I can’t eat spicy stuff.’— ‘No it’s not spicy. Why can’t you believe me? It's just the sauce. The sauce is red, sure. But it’s not spicy. Okay yeah they’re spicy butit's not gonna hurt you. Just one bite! Take one bite. Here.’ Tzuyu can’t hear Mina but she assumes Mina is also there with Sana, watching the girls bicker. “Why?” 

 

Hundreds of excuses come to her at once. She wants to say—Unnie I’m sick, can you go home now, or— Unnie, I’m having my heat, please come. But none of them are true and Tzuyu is not a liar. She just wants to see Sana. She misses her roommate even though they’re only apart for less than six hours. It's so silly.  She just doesn't want to sound needy. “Can I sleep in your room?” 

 

“Oh. Sure! Umm, and by the way sorry for your— your sheet. I popped them in the washing machine earlier. It’s probably all clean now. You can—“

 

“Can I borrow your clothes? My pajamas are in the laundry,” she cuts in. 

 

Huh? Yeah sure.”

 

“Thanks, Unnie,” Tzuyu says. 

 

“It’s nothing! You know but—“ There’s one second pause before Sana continues. “Are you on your—heat?” Sana says the last word in a whisper.

 

“No,” Tzuyu answers. She’s not due until tomorrow at the earliest. But it makes sense, maybe that’ll explain her irrational jealousy. That’ll explain her being all territorial. “I mean I don’t know.” 

 

“You don’t know?” 

 

“Not at the moment,” Tzuyu says. 

 

"It should be tomorrow night, right?" 

 

"Right," Tzuyu says, knowing that she has no excuse now. She hangs up soon after they bid their goodbyes. Still bothered with her thoughts, Tzuyu goes straight to Sana's room, changing her clothes with Sana's sleepwear. She picks an oversized shirt and nothing else, opting to sleep without shorts. 

 

Sana's room is pink. Way more feminine than hers. Pink covered beds. Pink blankets and pink pillows. Tzuyu has stayed over so many times there but she doesn't realize how comfortable she is in Sana's room. 

 

It smells a lot like Sana too. 

 

Tzuyu lays her head down on the pillow. Inhaling the faint lingering alpha's scent. She realizes she misses Sana and she misses her not because she misses her touch. Well, that too but in a I-want-to-cuddle-Sana unnie kind of way, and not in the I-want-Sana unnie-to-pin-me-down kind of way. 

 

Since when is she craving it? She can't remember. Has she, perhaps, taken Sana for granted that she assumes Sana will always want her unconditionally? What if Sana meets someone else later, in the future and decides that she no longer wants Tzuyu? 

 

The thought sickens her. 

 

Unnie, come home soon. Tzuyu closes her eyes and buries herself in Sana's blanket. It's already worn out, way past its expiry date. Sana brought it from Japan. It has cartoon carrot figures scattered all over the surface. Silly cartoons. Tzuyu stole it once when she was sick. Sana pretended that she didn't need it even though she did. 

 

She supposes she fell asleep sometime during the night because the next time she opens her eyes Sana is getting under the blanket. Her body heat envelopes her before she pulls Tzuyu into her arms. Her front meets Tzuyu's back. 

 

"Sorry, did I wake you up?" Sana pushes a thigh, fitting it between Tzuyu's long legs. 

 

"Yeah," Tzuyu says sleepily. A smile creeps up to her face. "What time is it?"

 

"1AM ish," whispers Sana. "Go back to sleep," she says. 

 

Tzuyu doesn't. She turns around, facing Sana, pressing her forehead against her. "How was the assignment?"

 

"We finished it," Sana says proudly, wiggling her toes. It's a subconscious reaction. Tzuyu notices that Sana wiggles her toes when she's happy about something. Most of the time Sana doesn't realize that she's doing it until Tzuyu calls her out on it. 

 

 She hums. 

 

Being practically pressed against one another, Tzuyu can't help but breathing Sana in. Sana smells so nice. Did she shower before she got on the bed? She smells fresh and clean. Tzuyu likes how calm and comfortable Sana can make her feel. 

 

"Your bed smells nice," she says raspily, still a bit sleepy. She meant that Sana smells nice but she doesn't want to admit it. She's too shy to do it. 

 

"It's the clean linen," Sana says with a giggle. "Sorry I ruined yours." 

 

"It's fine," says Tzuyu. "I don't mind." She means it. She doesn't mind at all, not when Sana is the one ruining it. 

 

"Thank you for helping me with my rut," says Sana, sounding mildly serious. "I know I can be a bit too much."

 

"You're pretty determined for a tiny alpha," teases Tzuyu. 

 

"Not this again, I'm not tiny," Sana fakes being insulted but then she laughs and pokes Tzuyu's tummy, earning herself a shriek. Tzuyu won't lose without a fight so she pokes back and soon enough they're wrestling each other. 

 

Once Sana has both of her wrists in a lock on top of her head, Tzuyu yells out her surrender, frightened and excited at the thought of Sana tickling her, but then their eyes meet in the dark dim light and suddenly Tzuyu's heart pounds harder against her ribcage. She stops laughing. 

 

Maybe it has something to do with Sana pressing herself between her legs. Or maybe it's because they're staring at each other so intensely. Either way Tzuyu notices how much Sana is affecting her; to her body and her heart.

 

"Unnie," whispers Tzuyu, voice trembling.

 

Sana's eyes flit down, to her lips and then back up again to her eyes. The action only makes Tzuyu blush. 

 

"Yeah?"

 

"You're getting turned on," says Tzuyu, feeling Sana grows hard against her. She can feel it pressing and twitching against her pelvis.  It's such an ego boost. Tzuyu's heart swells at the thought of Sana wanting her, even when she's not in the rut. Even when Tzuyu is not in her heat. 

 

"I'm sorry," says Sana but she doesn't sound sorry at the slightest. "Should I not?"

 

"It's okay," says Tzuyu, offering Sana a shy smile. 

 

Sana chuckles. Her light brown eyes— now dark— searches her, as if Sana is trying to read her. "Tzuyu?"

 

"Unnie?"

 

"Can I kiss you?" 

 

Tzuyu answers with a hum and Sana responds with a smile before she dives down, fitting their lips together. It's slow, most unlike their previous passionate ones filled with lust. Sana is so careful, as if she's trying not to break her. 

 

They kiss until Tzuyu is a panting mess, until her heart beats so loudly that she's certain Sana can feel it. She feels hot, hot all over, like she's feverish. Her brain turns to mush as Sana keeps sucking on her tongue gently. She's tingling all over. Her spine bows as she fights a moan from escaping her lips. 

 

"Can I take this off?" Sana lets go of her wrists and tugs on her shirt. Tzuyu clears her throat before she nods, afraid her voice will break if she says something. Sana wiggles her toes as she gently pulls the shirt over her head. Silly Sana and her silly toes. Tzuyu chuckles as she taps Sana's leg with her ankle. 

 

Now bare except for her white cotton panties, Tzuyu shivers as the cold air kisses her skin, but Sana holds her tighter, leaving hot kisses across her chest, soothing her with her tongue. 

 

With her hands, Sana massages her sides, then she scratches her tummy and drags her nails lightly until she's cupping her breasts, sending pleasant tingles all throughout. 

 

And then Sana dips down, bringing a nipple to her mouth, twirling her tongue around it, sucking it until Tzuyu quivers under her. 

 

The fact that Sana is being so gentle with her is giving her butterflies. It makes her feel so precious, so treasured. Tzuyu can't make sense of what she feels. Why does her heart beating so hard just from the simplest touch when they've done the filthiest things? Tonight she feels like it's their first time all over again although this time Tzuyu can't stop herself from feeling too much. 

 

When Sana slips a hand inside her panties and brings two fingers between her legs, rubbing her so gently, Tzuyu already feels like she's going to tumble into a release. 

 

"So wet," Sana says as she peers up into Tzuyu's eyes. "I love it."

 

Tzuyu cups Sana's face and kisses her because she can't stand how she looks at her. It's as if Sana is looking at her soul and she doesn't know if she should allow it.

 

"Cum for me Tzuyu," urges Sana between kisses. Warm, plushy lips brushing against hers as she's whispering her demands. "Cum for me, please," Sana says pleadingly as she picks up her pace, rubbing even harder, making Tzuyu shake and groan. 

 

As Sana keeps urging her, Tzuyu eventually breaks. Fireworks of pleasure run through her so suddenly that she can't help but moan, breaking the kiss. Blindy, she reaches for Sana, grabbing her shoulders, clawing her as her own hips move on its own, riding the orgasm. 

 

Sana catches her as she falls back down, planting her lips firmly onto her throat. 

 

"You're so pretty like this," says Sana, seemingly mesmerized. Still trying to kiss every inch of skin that she can reach. 

 

"Unnie," says Tzuyu, trailing her nails along the alpha's back, slipping her hands inside Sana's sweatpants, squeezing impatiently. 

 

She still wants Sana. One time is not enough. She needs her inside of her even though the orgasm robs her of her stamina. Even though her eyes are shutting close from exhaustion. She needs the alpha deep inside her. These thoughts keep nagging her as she's returning every kiss, but she's too shy to admit it. Too shy to voice out the filthy thoughts swimming in her head.

 

Sana seems to understand Tzuyu's frustration. She's peeling her own pants as she kisses Tzuyu's tummy, then she shimmies the omega's panties off, only to fall back on top of her, cock brushes against Tzuyu's drenched folds. 

 

"Kiss me," Tzuyu whispers sleepily. There's a part of her that desperately wants to rest, but the other part of her wants Sana to keep on going, to use her thoroughly, she doesn't want this to end. She'll do anything to hold on to it. So in the end she's staying put, allowing Sana to grind against her even when she can barely keep her head upright as the tiredness is taking over. 

 

Exhausted, she's slowly falling asleep despite the circumstances, despite that she's still throbbing and dripping against Sana. But then she hears Sana amidst the haze of dream, the gentle voice penetrating her foggy mind, asking her if she wants to sleep. Tzuyu nods, causing Sana to immediately stop. 

 

"No," Tzuyu protests, sounding almost whiny. 

 

"You're falling asleep," Sana nags halfheartedly, trying to untangle herself from Tzuyu's arms. 

 

"Inside," she says shamelessly. At this point she doesn't care anymore. It's probably the exhaustion making her honest to herself. They've done it a few times before, sleeping with Sana tucked deep inside of her, especially when Tzuyu is in her deepest heat, when a few passionate sessions won't completely satisfy the aching hunger. Her heat allows her body to accommodate the alpha's hardness, keeping Sana's cock warm and snug all throughout the night.

 

"Alright, alright," Sana chuckles, obviously amused. "You're so spoiled," she chides. Tzuyu notices that there's no bite to her tone so she responds with a satisfied hum, knowing well that she's won. 

 

The last thing Tzuyu remembers is Sana sliding her whole length inside of her, pushing inch after inch until she's pressing against her favorite spot. That spot that can make Tzuyu curl her toes and lose her breath. 

 

A gasp escapes her as her body is adjusting to the size. No matter how many times she's taken Sana, she still needs to adjust. Thankfully she's still so wet that it doesn't take her too long to adjust— much to her relief. And it feels amazing, being wrapped in Sana's arms, being filled with the alpha's thick girth. 

 

Toes wiggling, Sana finally rests her head on her shoulder, lips brushes the base of her throat. Warmth spreads inside of her chest as Sana drapes the rest of herself on top of her. 

 

Silly Sana and her silly toes. 

 

Tzuyu falls asleep with a content smile on her face. 

 

-



It's still in the middle of the night when Tzuyu wakes up drenched in sweat, aching and desperate. She's feverish and uncomfortable and it's not because of Sana's weight on her, instead it's the cramp in the pit of her tummy, gnawing her from the insides.

 

Tzuyu blinks the remaining exhaustion away as she recognizes the discomfort. It's her heat, it's coming too early, hours before its supposed time. Luckily Sana is still tucked so deep inside her, alleviating some of the neediness if only for a little.

 

But that's the thing, it's not enough. It's never enough. Tzuyu squirms as she shifts Sana on top of her, feeling the alpha's hardness slightly moves along within her as she adjusts the position of their legs. 

 

Prickles of pleasure run through her as Sana twitches and throbs in her cunt, putting pressure against the front of her walls; against that particular spot that can make Tzuyu breathless and begging for more.

 

Tzuyu squeezes her walls in response. It seems like Sana can feel it. The alpha gasps in her sleep. Her hips jerk up involuntarily. 

 

With the back of her palm, Tzuyu carefully rubs Sana's long, luscious tresses, feeling the soft, silky hair."Unnie?" She shifts again, locking her legs behind Sana's hips. The alpha's cock slides impossibly deeper now, pressing on all the right places. She hisses. "Unnie, I'm in my heat," she whispers shakily.

 

Sana groans awake a bit later. Peeling her blushing cheek away from Tzuyu's chest.

 

"Now?" 

 

She sounds so sleepy that Tzuyu almost feels sorry that she wakes her up, but then Sana's cock twitches inside of her, coming alive as Sana shifts on top of her. "Fuck, Tzuyu, you smell so good," she says as she's sobering up. 

 

"I need you," Tzuyu urges raspily. "Please, Unnie."



-





Sana is a heavy sleeper. She sleeps late most days and thus she's not used to waking up so early. She'd be mostly grumpy if she did. But she doesn't mind waking up to the smell of food, or the sound of her friends chattering away in her living room, or the sound of Tzuyu singing in their conjoined bathroom or better yet, waking up to Tzuyu being needy, waking up to Tzuyu squeezing her profusely with her wet, tight cunt. 

 

"Unnie, I'm in my heat," Tzuyu whispers as if it's a secret, as if she doesn't have her legs wrapped around Sana, as if Sana is not seven inches deep inside of her. 

 

The way Tzuyu looks at her is giving Sana butterflies. Doe, black eyes, staring pleadingly at her. "I need you," Tzuyu half begs, half whines, squirming under her. Her hands squeezing her shoulders. "Make it go away."

 

How can Sana say no to that? An alpha like Sana is powerless against omegas like Tzuyu. Especially when said omega is in heat. Every intake of breath is filled with the omega's sweet, hot scent.  Of course it doesn't help that Sana is in love with Tzuyu too. The omega call is drawing her in, ordering Sana to surrender to the wishes. So Sana obeys. She moves— grinding languidly against the girl under her. 

 

Tzuyu throws her head back, completely overwhelmed, but Sana hates it when she does that. She wants to see Tzuyu's reaction, wanting so desperately to see the pleasure in Tzuyu's face. So she grabs Tzuyu's face, bracing her elbows on the mattress to support her own weight as she slowly pounds into her. 

 

"Like that?" She jogs her hips, feeling herself sliding in and out so easily. Tzuyu is so wet. So wet. It's Tzuyu’s heat—her slippery walls trying to grip around Sana so desperately everytime Sana pulls away. Sana is utterly lost in the sea of sensation as she slams her hips down, filling Tzuyu over and over again up until the omega is crying in her arms. 

 

"Like that, Unnie. Just like that," Tzuyu whispers as she's staring into Sana's eyes pleadingly. Oh how Sana loves it when she does that— when she stares at her with her round, dark eyes, brimming with tears.

 

She dips down, kissing Tzuyu's cheek, then her jaw, then the swell of her blushing ear.

 

"You're taking my cock so well," she says, earning herself a chocked gasp. 

 

Tzuyu turns her face towards hers, plushy lips brushing Sana's lobe. Breath splashing against the side of her face, giving her goosebumps. 

 

It feels like a dream. 

 

"You're squeezing me all throughout the night," Sana teases before she plants a kiss on Tzuyu's jaw. Tzuyu might think that she's complaining but she honestly doesn't mind. She loves waking up with her dick already buried deep inside her secret love's pussy. Heat enveloped her so thickly that she couldn't think of anything else but tending to the omega's desire."Your cunt keeps waking me up. I couldn't really sleep." 

 

"I'm sorry, ah, I'm sorry," Tzuyu babbles. She's breathing so hard now that her voice comes out shaky.

 

"You should take responsibility," Sana says, picking up her pace. She glances down, watching her cock disappear inside Tzuyu's willing cunt over and over again. "You should let me fuck you as many times as I like tonight." 

 

These words that she's said— these dirty words are just pouring out of her mouth, but Sana can't help it, it's either that or she'd say something else, something that she'll definitely regret. 

 

It's there in the back of her tongue, itching to be let out. She can't stop thinking about it. The word haunts her every time Tzuyu begs, every time Tzuyu whimpers, every time Tzuyu clenches around Sana's cock. 

 

So she's distracting herself from saying it out loud, opting to say filthy stuff instead. "Will you be a good girl and let me use you?" 

 

"Yes! Unnie. Please," Tzuyu claws around her back. Her nails dig into Sana's skin. It hurts but it won't distract her from the mission. Sana knows they're going to leave marks, but she doesn't mind. She wants it to leave marks. 

 

Some days, after spending time with Tzuyu in her heat, Sana would have bruises and claw marks, and handprints all over her. She’d stare at herself in the mirror after, marveling at the aftermath of their passionate sessions written all over her. 

 

"Please what?" 

 

Tzuyu shuts her eyes. Her cheeks turn a shade redder. Apparently embarrassed. "Use me, please, ah, use me." 

 

Just like that Sana pumps harder and faster into the omega. Tzuyu lets out a satisfied moan, utterly pleased. It feels so good for Sana too, being cushioned by Tzuyu's plump thighs, cushioned by her pliant breasts. She loves burying her rigid length inside the omega's pussy over and over again. Tzuyu's cunt is just wonderfully snug and warm and soaked through, Sana loves it. She loves it so much. 

 

"You should come for me," urges Sana as she nibbles Tzuyu’s ear, loving the way it reddens as she teases it with her tongue. "Come for me."

 

Tzuyu can only nod urgently before she suddenly goes rigid in Sana’s arms. Her thighs shake violently as she’s locking Sana’s hips in a possessive embrace. It’s insane. It’s too intense. Sana stutters as the pleasure ripples through. Tzuyu’s pussy is clamping up around Sana so hard and so deliciously that the alpha almost comes along with her. 

 

If not for her logic, Sana won't stop at all. Sana would keep going. She'd pin Tzuyu down and knot her and cum inside of her, making the omega hers and hers alone.

 

Wide eyed, Sana tries to pull away when her knot is swelling rapidly, triggered by Tzuyu's orgasm. With how deep she is lodged within the omega now, surely she won’t be able to pull out if she doesn’t do it now. So Sana braces herself and tries to pull her hips back slightly, hoping to dislodge herself from the confines of Tzuyu’s grasping cunt— only to find herself falling back down into the omega as Tzuyu tightens her hold around her. Fortunately Sana manages to pull out her knot before anything. 

 

“No,” Tzuyu whines, seemingly frustrated.

 

“Sweetie, I— it’s too dangerous,” Sana pants. Her knot is grinded against Tzuyu's small entrance. God, Tzuyu feels so good that she's seeing stars. Sana is extremely close to her release. So close. “I-.”

 

“No,” Tzuyu begs. 

 

It’s the heat talking. Sana knows. Tzuyu did tell her that she didn't want the knot. There's no way Tzuyu would want to risk it, not when they're still in college, not when just yesterday she was still reminding Sana to pull out. Thus, she fights Tzuyu off, spreading the omega's legs and folding them up so Tzuyu can't trap her again. The little wrestling session gets her so worked up, however, that by the time she's wriggling herself out, she's cumming with half of her cock still encased inside Tzuyu's tight slippery heat.

 

"Oh, fuck!" Sana scrunches her eyes shut as the orgasm hits her so suddenly. She completely unseathes herself to rest her twitching cock against the omega's pelvis, shooting cum all over Tzuyu's tummy. 

 

By the time Sana is done, Tzuyu is quiet. The omega looks upset. She's still shaking but she doesn't say anything, she doesn't look at her. She's not hugging her. Clearly Sana does something to upset her. 

 

Not knowing what to do, Sana reaches out to the bedside table and grabs a tissue paper, wiping them both. "I came inside," she says regretfully. Perhaps that's why Tzuyu is mad. It's the only reason why Tzuyu should be mad. "I'm sorry. If anything happ-"

 

"I was hoping you would," Tzuyu says in her small voice. 

 

"What?" Did she hear that right? As if jump started, Sana's heart beats faster in her chest. She throws the tissue to the side and lays on top of Tzuyu, pressing their fronts together. 

 

Oddly enough, Tzuyu welcomes her with open arms, but still, the girl won't look at her, it's like she's avoiding eye contact at all cost. "I thought you said you're not on the pill," says Sana curiously. 

 

"I'm not, but," Tzuyu hides her face behind her palms, embarrassed by the pettiness of her request. "But please don't reject me." Tzuyu knows it's an irrational craving, wanting to be knotted, she knows it's stemming from jealousy. The thought that other omegas already did it with Sana is an utter torture for her. 

 

"Reject you?" Sana kisses Tzuyu's chin and peels the girl's hands off, wanting to look at her when she speaks. "You mean..earlier?" 

 

Tzuyu nods bashfully. Even though she's being difficult, Sana is still being so awfully nice to her that she finds herself at a loss for words. 

 

"It's dangerous. I'm not gonna put you in danger," Sana whispers. Eyes searching for Tzuyu's. 

 

"I want it," Tzuyu mutters stubbornly. Images of Mina and Sana flash in her mind once again. She pouts and frowns at the thought. 

 

"But what about the consequences? It's too risky" says Sana warily. 

 

It's true. She's aware of the consequences. Yet, how come the thought of having Sana's babies can make her feel so..content? Well, maybe 'content' is not the right word, maybe she can say 'fulfilled' but that sounds even worse. That sounds like she has feelings for Sana, or maybe she does

 

There's no way. Sure, Sana is nice and capable. She's also smart and good looking, and well spoken, but Sana has so many omega best friends. Who knows how many of them were Sana's cycle mates. Unacceptable. Just thinking about it makes Tzuyu feel like crying. 

 

Wait, maybe she really has feelings for the alpha. 

 

Tzuyu is blushing so hard that her face now feels uncomfortably warm. Is it possible? Does she really like Sana like that? 

 

"I mean," Sana cuts through Tzuyu's train of thoughts. "I mean you know I'll definitely take the responsibility if something happens, whatever that is." Sana raises an eyebrow. "But we should still be careful, right?"

 

The statement triggers something within Tzuyu. No, not the part where Sana tells her that they should be more careful, oddly enough, rather Tzuyu focuses on the fact that Sana promises to take responsibility if anything were to happen. The promise makes her feel weirdly giddy. It makes her heart beats faster. It makes her desire Sana more. 

 

 Tzuyu bites her lip. 

 

"Let's see about that," she replies quietly, earning herself a pointed glare. But Tzuyu knows Sana is not mad at her. Sana can't be mad at her, especially when Tzuyu is in heat, especially when the alpha is wrapped around the omega's arms. "Unnie," says Tzuyu meaningfully, trailing her fingers around Sana's shoulder. 

 

Sana smiles before she dips down, planting a kiss. She kisses her once, then twice, then more, until Tzuyu closes her eyes, until all Tzuyu can think about is Sana's lips and the way they move against hers. 

When Sana deepens the kiss, Tzuyu hums. Her lips are tingling and swollen now from the passionate kisses that they share. Sana moves her hips, sliding her cock between the omega's legs, hitting Tzuyu's clit over and over again as she pushes and pulls. 

 

It feels so good. So good that Tzuyu's thoughts melt away until there's only pleasure in her mind. But then Sana kisses her nose and says, "Excuse me," in her tiny voice as she wriggles her thickness inside of her and the thought surges up again, her heart becomes a puddle of mess as Sana bottoms out in one solid stroke. 

 

"Unnie, oh my God," cries out Tzuyu. The words slip out of her before she can hold it in. 

 

"Are you okay, baby?" Sana nudges her nose with her own. Her voice is shaky from bliss but she still sounds full of concern.

 

The simple, gentle question makes her heart jumps. Isn't Sana being too sweet? It's unfair. Who gives her the right? 

 

"Mm, move please," says Tzuyu breathlessly, hiding her face in Sana's shoulder. She doesn't want to admit how good she feels. How euphoric Sana makes her feel. She just wants to curl up and hide. But then Sana pulls out slowly, only to slam it back inside so suddenly, making Tzuyu chokes.

 

"Like that?" Sana taunts as she folds Tzuyu's legs up, hooking them up on her shoulders, exposing the omega. Lust dripping in her voice. "I know you like it like this," the alpha whispers in her ear as she jogs her hips, dragging her hard, thick cock in and out of the omega. She's hitting that sweet spot deep within Tzuyu. A spot that only Sana can find. Sana's own favorite spot. "Or do you need this too?" Sana slips a hand between them, rubbing Tzuyu's clit with her thumb. Quick, tight, tiny circles, pushing Tzuyu to the brink almost immediately. 

 

"Bu-but," Tzuyu stammers. The truth is, Tzuyu is nearing again, and she's ashamed for it, ashamed that she's going to cum too fast. 

 

"You're gonna cum around my cock, because you're a good girl, aren't you Tzuyu?" Sana kisses her cheek. "Say it. Say you're gonna cum for me." 

 

Tzuyu blushes so hard now. She can't believe her own ears. "Gonna cum for Unnie," she chokes out. 

 

"That's a good girl." Sana is so smug. She knows Tzuyu is putty in her hands. She knows and maybe that's why she keeps looking at Tzuyu like she's staring into her soul, as if she's saying that she owns her. Honestly, as an omega, Tzuyu loves that feeling, love that she's trapped in Sana's arms. Helpless. Sana who keeps pounding into her while rubbing her clit, whispering dirty stuff in her ear; "Baby, come for me." "Don't hold it in, just cum for me." "Your pussy so good, I can't stop fucking it." 

 

When Tzuyu comes again, Sana won't stop, she keeps pumping into her like she's in a trance, like she can't help but fucking her. Lost in the omega's intoxicating scent. Amidst the moment, Sana stares at her, watching Tzuyu at her most vulnerable moment, watching her as waves and waves of pleasure roll her down into oblivion. And it makes her feel seen. 

 

Once she's sobering up, Tzuyu peeks down, curious. Sana's, wet, fat, girth disappears into her once again as Sana keeps her delicious pace. She clenches around the pulsing shaft, beyond pleased. If only they can stay like this forever. Locked in an embrace together. 

 

The omega wants to be knotted, not only that, she desperately and utterly needs to be knotted. When Sana starts swelling against her entrance, the need tenfolds into this unbearable urge. Tzuyu bites her lip, holding herself from begging. 

 

"Ugh, fuck Tzuyu, I'm so close," breathes Sana. Face crimson. Her skin is glowing, sweat coating her neck and collarbone. The sound of their skins slapping against each other's echoing in the room. "I'm so close." 

 

It's as if Sana is pleading, pleading for Tzuyu to hold her as she's rapidly climbing into a climax. Tzuyu listens to the silent plea. She digs her heels around Sana's hips, pulling the alpha impossibly deeper inside her, sucking her in. Sana's knot swelling rapidly, kissing her entrance over and over again as they grind against each other. Tzuyu feels her head spin as the pleasure suffocates her. 

 

"Unnie, knot me," she whispers. Sending Sana a pleading look. She knows she shouldn't say it. She's not thinking right. She's too lost in her own heat to know what she's saying. "Please, Unnie, knot me," she begs. 

 

"Tzuyu-you, stop," Sana wheezes. Contrary to what she says, she's not slowing down at all. The swell of her knot is slipping into Tzuyu's welcoming cunt, swallowed over and over again as she's pumping in and pulling out roughly. At this rate, if Sana doesn't slow down or stop anytime soon, she will definitely cum inside of Tzuyu again. 

 

"I want it," Tzuyu hisses. "Please Unnie." 

 

Tzuyu doesn't realize that she's crying until Sana kisses the tears away. Sana soothes her with slow kisses as she's plunging her knot inside Tzuyu's tight, slippery walls. Perhaps it's the alpha in her, wanting to soothe the crying omega, whatever it is Sana's will quickly dissolves into thin air as Tzuyu's silent cries echoes in her ear. 

 

So against her better judgment, she's pushing her cock in until she's bottoming out, until her knot swelling throughly and is completely swallowed by Tzuyu's silky cunt. It's amazing. It feels as if Sana's soul transcends into space.  The omega feels so warm and wet around her cock. Sana can't believe it. She can't believe that she's doing this, but at the same time she can't fight the urge. She wants to be buried deep inside the omega. To claim her spot there. To own the omega. 

 

 They are hugging each other so tightly. If they don't Sana has this irrational fear that she's going to lose the omega forever. 

 

With their foreheads pressed against one another, Sana finally comes, expelling ropes and ropes of cum inside the omega's clenching cunt. Tzuyu moans in satisfaction, half laughing, half humming, as she's milking every drop of Sana's cum deep inside her. The knot seals any from dripping out. Tzuyu squirms around, loving the way Sana pressing on all the right spots. 

 

"Oh wow, Unnie," Tzuyu says. She can't wipe the smile from her face. "Unnie." She buries her face in Sana's neck, her hips still moving as she's clenching around Sana's thickness. 

 

"I love you, Tzuyu," Sana suddenly confesses while she's catching her breath. Her lips pressing on her temple, leaving gentle kisses. "I'm sorry." 

 

What? Tzuyu feels the time freeze as she's digesting the words. Does she hear right? Tzuyu's jaw drop. She feels a giddiness climbs up her throat. "Don't be sorry," she says. "I'm happy to hear it."

 

"If you don't feel the same, this won't change any-"

 

"I said I'm happy." 

 

Excitement crosses Sana's face. She shifts away so she can look at Tzuyu more clearly. The knot prevents her from detaching herself so Sana braces herself with her arms as she's scrutinizing Tzuyu's face. "What are you saying?"

 

Tzuyu considers her words. The truth is the answer is not a simple yes or no. "I don't know what I'm feeling now but, but I do know that I'm not looking for anyone else. I do know that I only want you."  If she's being honest, Tzuyu knows that she's slowly falling for her roommate. She's not there yet, but she's close. Really close. She just can't say it yet. She hopes Sana is satisfied with her answer. 

 

"That's practically the same," Sana says with a shrug. "I win anyway." 

 

"Win what?" Tzuyu fakes annoyance but she can’t stop smiling.  

 

Sana wiggles her toes, apparently happy. "This. Everything," she says confidently. 

 

Silly Sana and her silly toes. Tzuyu hides her smile, gritting her teeth together. "I'm thirsty," says Tzuyu. 

 

"Then we have to go to the kitchen," says Sana seriously before she suddenly scoops Tzuyu in her arms. But alas Sana is only a small alpha. They have to manouver themselves out of the bed with much difficulty (and much laughter, and tickles, and teases) before Sana can safely carries Tzuyu in her arms to the kitchen. 

 

Once they arrive there, Sana puts her on the counter and together, with a little bit of team work, they manage to pour water into the cups. Tzuyu drinks but not before she glances down, stealing a peek at how their bodies are joined together. Now that the swell of Sana's knot rapidly disappears, Tzuyu can feel some cum dribbling down to her inner thigh. She checks to confirm and sure enough, she sees the mess between them.

 

Noticing the look, Sana takes the empty cup from Tzuyu's hand. "You still want more?" Sana gently rubs her tummy, making Tzuyu shivers."Or are you tired?" 

 

Tzuyu suspects that the question is only for formality because Sana must have known how much Tzuyu desires her right now. Her omega scent is still thick in the air. She's surprised that Sana is not losing her mind right now considering how much she's pumping out. She nods guiltily. 

 

"Then you'll have more," Sana says, giggling. "Don't regret it now," she warns jokingly before she slips a hand between them, rubbing Tzuyu's clit with her fingers. "Or maybe I should hear you say, please first?"

 

"Please, Unnie," says Tzuyu shamlessly. Her hips jump once Sana makes contact with her clit. It feels so good that her toes are curling from the sensation. 

 

So Sana takes her in the kitchen counter, and after Tzuyu comes, Sana carries her to the sofa and bends her over the arm rest. She's fucking her until Tzuyu is screaming against the cushion, until Tzuyu is blushing all over. Until she's pliant and helpless. Sana knots her there too, on the sofa, triggering Tzuyu to another mind shattering orgasm. 

 

Then, by Tzuyu's heated encouragement, Sana knots her on the coffee table. Tzuyu watches as Sana sinks her knot into her slowly, watching it slides against her drenched folds and swallowed by tight ring of muscle. Watching Sana's tummy twitches as she's shooting inside of her. 

 

Not once does Tzuyu stops her. She doesn't want Sana to stop. She wants her to take her as many times as she likes and as passionate as she wants. She's insatiable. Always hungry for more. Tzuyu's heat is only getting worse that by the time she realizes that her body is shutting down on its own, she's still bouncing shallowly on Sana's lap on the sofa, legs spread so ledwly, Sana rubbing her clit lazily while her knot pulses inside her. 

 

"Bed," she says as her head lols to the side, clutching at Sana as another orgasm wrecks her entire being. Sana chuckles and carries her to the bed. The alpha's knot is still tucked deep inside of the omega. Both fufilled and satisfied. They fall to the bed still pressed against each other. Tzuyu on top and Sana is her pillow. 

 

She doesn't regret what happen. She'll deal with it later. All she wants right now is being wrapped tightly in Sana's arms. Basking in the alpha's scent. Knowing full well that nothing can harm her as long as she's with Sana. 

 

-








"You're not pregnant," Doctor Hwang announces. Her eyes are glued to the small monitor on her right. She's moving the ultrasound scanner left and right, gliding it across Tzuyu's flat tummy. 

 

Earlier today, Tzuyu asked Sana to go to a gynecology for a check up. Sana dropped everything she planned for the day and went with the omega to the hospital. She wasn't going to let Tzuyu find out by herself. 

 

"Oh," Sana says, not knowing what to say. There's a part of her that wishes for it. Crazily enough. But she knows they're not ready for a baby, not when they're still in college. However if the result turned out positive she'd celebrate it all the same. After all it's her baby and Tzuyu's.  

 

She squeezes Tzuyu's hand and turns to the girl beside her. Tzuyu is still looking at the monitor with an unreadable expresion on her face."We suspects so, but we still want to make sure," says Sana carefully. 

 

"That's a shame," Tzuyu instead says, making Sana chokes on her own spit. "I'm just kidding," she later says blankly, but Sana knows that Tzuyu was indeed just joking around. She smiles. 

 

"Well I'm sorry to hear that but if you want to keep trying, you can," says Doctor Hwang, completely oblivious of the joke. "Just avoid the 'after-rut.' After a rut, alphas can only produce low motility sperm, making it almost impossible for a succesful pregnancy."

 

"Even during heat?" 

 

Tzuyu smacks her shoulder, making her groan in pain. 

 

"Even during heat," Doctor Hwang confirms. "The heat will contribute to, at most, 10% possibility increase, because the omega is ovulating but it's still highly unlikely since the problem is the semen that the alpha produces."

 

Once they exit the hospital, Sana grabs Tzuyu's arm and swings it as they walk to the parking lot.  "So how do you feel about the whole thing, really?" 

 

Tzuyu makes her trademark thinking face. She blinks slowly for a few times before she comes up with an answer. "I don't mind either way. If I were indeed pregnant, I know I'll be alright, financially at least," she says truthfully and Sana know she's not lying when she says it. She knows how privillige Tzuyu is. "But I also know that you'd be by my side."

 

Sana smiles. She feels so honored that Tzuyu is thinking so highly of her. 

 

"Lucky that you know I'm in love with you." She pouts. 

 

"I love you too," Tzuyu says casually as she unlocks her car. 

 

"What?" Sana stops in her tracks. Eyes widen. She can't believe what she hears. "Tzuyu if you're jo-"

 

"I'm not. I'm in love with you," Tzuyu says with a sigh, seemingly frustrated and shy that she has to repeat herself. They're now stiopping in the middle of the small pedestrian way. Pregnant ladies and their alpha partners stare at them visciously as they try to manouver their way without hitting them, but Sana can't care less about them. All she wants right now is to get an explanation from Tzuyu. "I realize it in the doctor's office just now."

 

"What?" Sana feels her knees turning to jelly. She balks. "What- how?" 

 

Tzuyu's eyes now turn soft. Under the bright morning sun, Tzuyu's eyes appear lighter than they usually are. Dark brown orbs staring at her fondly. There’s a small smile on Tzuyu's lips now. "When I realize that I want to have a family with you. When I know that I trust you 100% with myself. When I know that I'm completely safe as long as I'm with you," says Tzuyu slowly, every sentence comes out perfectly clear. For once Tzuyu doesn't hide when she speaks. 

 

Sana smiles. Sana smiles so wide that her cheeks are now hurting. "So, do you want to be my girlfriend?" Maybe the timing is off. Maybe she's too eager, but Sana doesn't want to fight it. She wants to be swept away by the moment. She wants to be swept away by Tzuyu. 

 

"Unnie, If I said I want to have your babies, then of course I wanna be your girlfriend," says Tzuyu as she walks off. 

 

The words triggers something within Sana. Something primal. It's ridiculous. Tzuyu is so silly. Sana chases her and Tzuyu immediately runs when she realizes that Sana is tailing her, shrieking happily all the while.
