A Different Kind of Love

Summary:

Chiaki's (an omega) mother has a weird way of protecting him from creeps and perverts.

Today, it will be put to the test how effective it actually is.

Notes:

Hello everyone, just a heads up, i based the omega biology on a certain doujinshi called “Omega on the Shore” by Danzi Engine. If you want clearer visuals on it you can check it out, but as always mind the tags wherever you decide to check and immediately close it if you see anything you don’t like, don’t let a stranger on the internet tell you to do something you don’t want to.

If not, the brief explanation is that inside the omega butt are 2 channels: one leads to the male vagina while the other is for the colon.

Anyway after all that, i wrote this all in one sitting and is unbeta’d so either point it out and i’ll fix it or if you cba just bear with it. Ages are never mentioned in this fic so choose which are to your liking.

As usual, mind the tags, i don’t condone these actions irl, don’t like don’t read. All that shebang.

The 2 drawings were made by me.

(See the end of the work for more notes.)

Work Text:

Chiaki doesn't usually end up riding the train this late, when it’s peak rush hour and everyone is crammed together like sardines. But he ran late from his library duty thanks to a group of delinquents messing up the books; basically just leaving all of the pieces strewn across the floor.

As the library's sole committee member, he didn't have any help putting them all back on their shelves.

His extremely strict alpha mother is going to chew him a new one for being late to his curfew. She always coddled him, way beyond the point of suffocating, she'd have him glue to her side if she could. She always said it was only because she was worried about him being an omega in a world of alphas, claiming how she knows how alphas stare at an unmated omega like a starving lions to a slab of juicy meat.

The train jostled him out of his thoughts, the sharp turn it took shifting the gravity inside the cart and he eventually ended up firmly pressed up against the wall. He felt the buttons of his shirt uncomfortably press against his soft skin and was about to frown at it like it was life's biggest problem before he finally notices the heat enveloping his back.

He was about to ignore it, as it was a common occurrence in pack trains–but what wasn't common was the thick fingers working its way down the hem of his pants.

His heart drops to his stomach as a chill fills his every nerve endings, but in reality, it was warm with bodies pressed against each other in the small cart. It feels like his sweat was steaming and fogging up the glass he was pressed against.

He chokes on the breath he didn’t notice he was holding when the stranger behind him shimmies his hand underneath his briefs, cold pads rubbing up and down his crack before unceremoniously plunging even lower.

Only to be met... With soft leather.

At this point Chiaki was tearing up, not only from the fear of molestation but also the mortification that his secret was exposed.

His mother had a weird way of protecting him from alphas. One morning, after breakfast, his mother had shoved a dildo into his male vagina and fastened him with the chastity belt built into it that only she has the keys to. She only takes it off after dinner while he goes off to shower. Even putting it back on afterwards when all that's left to do is to sleep, claiming that alphas could break in and rape him in his sleep so he has to be protected then as well. 

What he never understood was why it had a vibrate function. At random times during the day, it will suddenly jolt to life with varying degrees of intensities and lengths, and as the stranger behind him was feeling around the leather and his fingers traced the hard plastic end of the dildo, it chose that moment to come to life. At the highest intensity, as Chiaki has learned over the years, and it was so intense even the stranger behind him jolted in surprise.

He hopes that would be the end of it, that no entry was possible so the molester just leaves thinking he's some sort of pervert who gets off at being stimulated in public.

But to his surprise, the molester eases on and starts poking at his stretched sphincter. His finger hooking forward as it tries to squeeze into the already occupied hole. Chiaki groans as the man slips 2 fingers when his body finally notices the distress to his nethers and provides some sleek, the general musk of sweat from people crammed into a warm tin can on a summer heat wave strong enough to hide his omegan scent as he was forced into a state of arousal for his own body’s self defense.

The molester starts thrusting those 2 fingers back and forth, and sometimes curling them and pulling at his rim as if to check if he'd loosen enough before eventually forcing a third finger in. The man twists and stretches his fingers as much as he could in the cramped space; both within his hole and the cart they were in.

He could feel the man lean closer to his nape, meeting a collar snugly around his neck, also locked and a courtesy of his mother’s protection.

Then it happened. It was one particular motion.

The man’s fingers searching within his warm tunnel was clumsy and, in his careless wandering, had disturbed the lengthy dildo lodged within him, pushing the toy just enough for the vibrating tip to graze against his sensitive cervix.

All at once that sudden mishap had jolts of electricity coursing through all his limbs. His entire body shudders and twitches and he instinctively leans forward–as much as their position could allow him–and was about to release a moan that would shatter the calm rumbling of the train before the stranger shoves 2 fingers of his other hand down his throat. The only sounds he could make are muffled choking and gasping; something easily ignored in a crowd as someone just needing to cough–especially when the molester presses his finger down his tongue so he couldn’t make any more noises.

Uninterested to mess around anymore, the molester pulls his pants down to just below the swell of his ass. Chiaki quietly whines when he feels the man readjust himself, a bit of shuffling and he could feel the hot rod poke at his occupied hole. He felt the soft spongy tip swirl around his entrance for a bit, likely lubing his cock with the excess sleek. 

The omega has just started to sob, twitching away from the cock near his ass as if there was anywhere to run to in his corner. At the same time, the alpha grabs a handkerchief and uses it to wipe the stray tears down the omega’s cheeks. It almost seemed like a kind gesture, before the molester balled up the piece of now salty cloth and stuffs it into Chiaki’s mouth.

All at once, the molester slaps his hand over his mouth, his fingers squishing his cheeks while his other hand grabs his hips and forces it down to meet with his hips thrusting up. 

The pained wail he let out properly concealed, even if Chiaki didn’t fear social ridicule as much as he did, the sudden and painful penetration caused him to lose all authority he had over his own body.

He throws his head back, along with his eyes rolling into his skull as if his own vision wanted to hide away from reality. His knees buckle under his own weight as he loses all strength, which inadvertently causes him to sink even deeper into the impaling dick; whining into the wet fabric in his mouth.

The molester didn’t move for a short while, only huffing hot breaths onto Chiaki’s ear. Just basking on the impossibly tight heat twitching and suctioning on his cock, the omega even came with a sex toy vibrating against his dick for his own enjoyment. What a lucky find. 

Chiaki’s eyes were beginning to glaze over, darkness creeping onto his vision. His thoughts were swimming when he finally felt the man start moving. The velvety walls clinging onto the cock even as he drags it out to harshly push it back in, the cock twitching happily whenever the other would clench desperately against his rod, as if unsure if it’s trying to push him out or suck him in further–either way, the alpha feels pleasure from it.

Their position could only allow for shallow thrusts, but the way the man violently grips his hips and their groins meet as if he had personally offended the man told him that the man wanted nothing more than to press him down and put his entire being into burying his cock as deep it can go into his colon. 

As the molester desperately chases after his own release, his careless movement once again disturbs its chamber partner. The dildo remains steadfast and in place within his male vagina, but after going so long with a dildo that never moved from its place, the plastic being dragged back when the man pulls out and shooting back into place due to the chastity belt’s resilience was close to maddening. The angry vibrations brushing against the lips of his cervix whenever the dildo retracts and shoots past its place, causing his hips to twitch and add variety into the molester’s pleasure, did not help whatsoever.

The alpha had switched to now grinding their hips together, the drag of the Omega's previously virgin colon felt like a hug that didn't want to let go. The molten heat convulsing against its violent intruder only serves to welcome the cock even deeper, and the alpha wasn't one to deny an invitation; as unwilling as it may be.

He now fully puts his weight onto the omega, Chiaki actually having a hard time breathing how hard his torso was sandwiched between the wall and the man. Another pitiful whine escapes his throat but dies on the gag as he could feel the tip of the cock poke at the end of his colon. No doubt, if he had the space to, he would fuck straight into the Omega's guts–rearranging them to his cock's fancy. 

After he fucks into my cervix and leaves me surely pregnant and bloated with his cum. A sick and terrified part of Chiaki's brain supplies.

The alpha was close, he could feel his knot start to inflate as it was starting to catch on the already stretched rim with every shallow thrusts. He wants to knot the omega so badly, knot him while the dildo still vibrating angrily buzzes, so the toy could press into his walls in new ways and without any reprieves. 

He peeks at where they were connected, the previously pretty pink hole that housed the obscene dildo now an angry red as it’s forced to accommodate two now.

If he knotted the omega, it would surely break his mind. Destroy his hole and leave him gaping for the entire train cart to see.

But he can't. 

Not now.

He has to get off soon and his current destination isn't anywhere to keep a cute little boywife restrained with his legs forced open and ready to be bred whenever he feels like it.

With a bit of maneuvering, he pulled out slightly so that his knot fully inflates just outside the Omega's hole, but still shooting his cum into the raw and sensitive walls.

Smirking, he saw the Omega's tummy slightly bloat from the amount of cum. His smirk turning into a full grin as the dildo stops all but a few dribbles of cum from spilling out his ass, forced to carry the seeds of a man he doesn't know until how long he gets home.

The molester took his phone and captures the moment of absolute ravageness and ruination of Chiaki’s hole, before quickly rummaging through the other's bag for his wallet and phone. Taking another picture of his handiwork, but this time with the Omega's I.D. in frame, to put a face and name–”Chiaki”, what a pretty name–on the debauchery he committed. Then he saves the Omega's phone number onto his own device, he quickly glances at said omega and sees that he's just completely out of it; eyes fully glazed and barely reacts when he snaps his fingers close to his face.

With a smirk, he messily puts the Omega's belongings back in his bag, pulls the other’s pants back in place after he did his own–because he's such a gentleman–and it was all right in time for the announcement to ring that he was at his stop.

He'll send the pictures to the omega later so that he can invite him for some more… fun times with a few gentle coercions. 

As for Chiaki, he doesn't know how he’ll tell his mother that plugging his hole doesn't ward off rapists when she eventually sees the red, raw and loose hole along with the gush of cum when she undoes his chastity belt tonight. 

Notes:

Welp, hope you enjoyed it! If it seems rush or lacking any set dressing, it’s because i wanted to try writing a shorter story in comparison to my other works… (to me 1k~2k fics are on the short end, no offense on anyone thinking differently). So if anything feels rushed in places welllllll let’s just ignore that shall we!

Anyway, kudos and comments are always appreciated, i’m still not that good at writing but im trying!
