Chapter Text
By the time Noah and Melissa were getting ready to leave the house with Mila, Stiles became nervous for a multitude of reasons. He was nervous because Mila had never spent the night away from home before and Stiles felt she was too young. Also, he was nervous because Mila leaving meant that there was the possibility he was going to finally lose his virginity that very night. Sure, he had been waiting for this ever since he and Derek got together, but still, the whole loss of virginity was kinda scary. They would be going all the way. Not just hot make-out sessions that have them coming in their pants. Full on dick in ass.
“Bye Papa!”
Stiles shook himself out of his thoughts and took Mila into his arms, peppering her face with kisses until she giggled and smacked his face. “Bye sweetheart. You be good, okay? And listen to Grandpa and miss Melissa.”
Mila adopted a serious looking face and nodded profusely. Stiles couldn’t help but laugh. He handed her back to his father. “If you guys have any problems or need anything, we’re only a phone call away.”
Noah shook his head. “We’ll be fine kiddo. I raised you, after all.”
“Yes, but you haven’t dealt with a child this young in a long time.”
“If she’s anything like you, I’m sure we can handle it.”
Stiles glared. “Rude.”
Derek chuckled and rubbed his back. “They’ll be fine, baby.” He kissed Mila on the nose. “We’ll see you tomorrow.”
“I promise we’ll call before we come,” Melissa winked.
That caused Stiles’ pulse to skyrocket in fear again. Derek glanced at him but didn’t say anything. As soon as Noah, Melissa, and Mila left, Derek turned to Stiles.
“Hey, you okay?”
“Yup.”
Derek narrowed his eyes. “You’re a horrible liar Stiles.” He cupped his chin, “Hey, you do know that we don’t have to do anything you’re not ready for.”
Stiles shook his head. “I’ve already made you wait long enough. I-”
Derek placed a finger to his lips, “And I’ll continue waiting. Baby, we don’t have to rush.”
Stiles sighed, “I know Derek, and I appreciate how…gentlemanly you are. I don’t want to wait. I’m ready. I just…”
“Nervous?”
Stiles nodded. Derek kissed his lips as they headed upstairs.
“Would you believe me if I told you that I am too?”
That caused Stiles to stop short. “You? What are you nervous about? How could you be nervous, I’m sure you’ve had sex before.”
Derek chuckled as they entered the bedroom. “Yes, but never with a guy. Sex with a guy is very different from sex with a girl.”
Stiles leaned against the door and stared at him. Crossing his arms over his chest and just watching Derek as he sat on the edge of the bed and stared back at Stiles. Derek chuckled and patted the seat next to him. After a few minutes, Stiles walked over and joined him.
“I don’t know if you’re lying to make me feel better or wholeheartedly telling the truth, but I don’t believe for a second that you, Derek Hale, alpha of the baddest pack in all the land, would be nervous.”
Derek snorted. “First off, there are probably badder packs out there. Secondly, why would I need to lie? Just because I’m an alpha doesn’t mean I don’t get nervous. I can’t tell you how many times I’ve been nervous and it's not just about sex. I was nervous when we first met and when I realized you were my mate. I was extremely nervous when I knew I had to explain to you what I was. I had no idea how you would take it.”
“Really?”
Derek nodded, leaning over and kissing Stiles’ neck. “Really.”
Stiles arched his neck as the words flew out of his mouth. He really loved Derek’s mouth. Derek chuckled as he continued to nibble Stiles’ neck.
“Look at you, I haven’t even done anything and you’re already moaning.”
“F-Fuck you. You k-know my neck is…sensit-Derek, please!”
“Mhm, just like your nipples, your inner thighs, your belly button…need I continue?”
Stiles tried to hit Derek, but just ended up flailing more than normal. Derek just laughed before pulling back. Stiles sat up and frowned.
“Relax,” Derek tapped his nose before Stiles could speak. “I need to talk to you first.”
“Sex first, talk later.”
Derek chuckled again, shifting so he sat back on his haunches. “I’m serious. We need to talk so you know what to expect.”
Stiles glared. “Seriously Derek? I know what to expect. I may be a virgin but I’m not naive. Your dick, my ass. I’ve seen enough porn to know how it works.”
Derek flicked Stiles’ nose. “What if I told you that sex with a werewolf is different?”
“Different how? You have all the same parts.” Stiles arched an eyebrow.
“Come on Stiles. You can’t be that clueless. I know you’ve read the books I gave you.”
“Yeah, but none of them mentioned werewolf sex. I think I would remember that chapter. You wanna just tell me so we can get this show on the road?”
“So romantic.”
“Screw you. I’ve been waiting for months. Seriously, Derek. What is the big issue?”
Derek sighed. He wasn’t sure how to exactly bring this up. Because what if after all this, Stiles changed his mind? He couldn’t live with it if Stiles didn’t want anything to do with him anymore.
“Derek,” Stiles pressed his palm between his thighs and rubbed. Derek moaned. “C’mon. I don’t know what has you all nervous, but nothing, nothing is going to make me change my mind. I love you, okay? I love you and I have been wanting to sit on your D since I saw you in the diner all those months ago.”
To further prove his point that nothing would scare him off, Stiles undid Derek’s pants and wrapped his hand around Derek’s dick.
“Fuck,” Derek growled, eyes nearly rolling into the back of his head.
It wasn’t the first time Stiles had touched his dick, but it had always been with his pants on.
“I…” Derek started to speak when Stiles kissed him to cut him off.
“Don’t care. Want you. Derek, please.”
Derek sighed but eventually gave up. Instead, he focused on getting Stiles naked. When they were both naked with Stiles laying back against the pillows, Derek slotted himself between his legs as he reached for the lube.
“You sure?”
Stiles wrapped his arms around Derek’s shoulders pulling him closer to kiss him.
“Yes. I’m ready. I trust you.”
Derek slicked up his fingers and proceeded to try and distract Stiles as he slipped a finger into him. Stiles groaned against the intrusion. Derek continued to kiss him, attempting to soothe him as he took his time fingering him. Each time he added a finger, he would continue with just those fingers until Stiles was loose before adding another. By the time Derek had three fingers inside, Stiles was a mumbling, sobbing mess.
“D’rk. Pl’se. ‘m ready.”
Derek removed his fingers and looked at his boyfriend. This man was more than just his boyfriend. He was his mate. His partner. His entire world. Derek couldn’t imagine his life without Stiles in it.
“Ready?”
Stiles nodded, “Wan’ you.”
“You have me. I’m yours.” Derek slicked up his dick and gripping Stiles’ hips, slowly pressed into him.
Stiles let out a loud moan as he arched his back.
Derek continued pressing into him as slowly as possible so as not to cause any pain. Once he was fully seated inside he stilled letting Stiles adjust.
“Fuck, you’re huge,” Stiles breathed.
“I am. You okay?”
“Fuck. Yeah, just gimme a minute.”
Derek kissed him. “Take your time, baby. You feel good.”
After a minute, Stiles gave Derek a nod telling him to move. Derek carefully rolled his hips, giving an experimental thrust. Stiles’ mouth dropped open and his eyes fluttered. Derek did it again. This time, Stiles cursed as his eyes fluttered shut. Derek chuckled as he continued with the slow thrusts. Eventually, Stiles whined.
“What’s wrong?” Derek stopped and looked down at him.
“You’re going too slow.”
“I’m going too slow?”
Stiles huffed. “I’m not made of glass, you know. I won’t break.”
“Is that so?” Derek snapped his hips.
“Fuck! Yes.”
“Well, okay.”
Derek angled himself and began thrusting faster. Stiles quickly wrapped his legs around Derek, pulling him deeper inside.
Derek thrust hard and deep. He nibbled on Stiles’ ear. “Feel how deep I am? That feels good doesn’t it? Your body is sucking me in so sweetly. Bet I can do this to you all night long and you wouldn’t care, huh?”
Derek was never much one for dirty talk, but when he found out how much Stiles loved it, he tried to do it as much as possible. Derek kept up the dirty talk as he increased the pace of his thrusts. Stiles moaned, reaching for his dick but Derek slapped his hand away.
“Not yet.”
“Derek, please.” He reached for his dick again.
Derek took Stiles’ hands and draped them over his back. “Not yet.”
Stiles whined, but Derek didn’t relent. All too soon, Derek could feel his knot forming and he rocked his hips harder, pushing it inside.
Stiles’ eyes widened. “Derek, what the-”
“Shh, relax. It's just my knot.”
“Oh, just your knot? What the hell-” Stiles was cut off when Derek wrapped his hand around his dick and stroked it. “Fuck! Derek, fuck, please!”
Derek knew exactly what Stiles was asking for. He couldn’t remember when exactly they found out that Stiles liked this, but whenever Stiles wanted to cum, he begged for it. Derek unsheathed a claw and very slowly, scraped the underside of Stiles’ dick.
“Fuck! Derek!” Stiles arched his back and screamed as he came, spilling all over his stomach and Derek’s hand.
Derek kissed him as he slowed his thrusts but didn’t stop. Stiles whined.
“Derek, come on.”
Derek chuckled. He picked up the pace again and minutes later, he too was coming. He slumped over Stiles while trying to keep his weight off.
“Fuck. That was…” Stiles panted.
“Yeah.”
After a few minutes of silence in which both boys attempted to calm their breathing, Stiles rolled his hips causing Derek to moan and grip his hips to still him.
“What did you do to me?” Stiles asked.
“I’ve knotted you.”
“You…knotted…me? What does that mean?”
“This is what I was trying to explain to you. It only happens when an alpha finds their mate. Basically, in simple terms I’ve locked us together.”
“For how long?”
Derek shrugged. “I don’t know. Shouldn’t be too long. Does it hurt?”
“No. Feels…weird, but doesn’t hurt.”
Derek nodded. He kissed Stiles before maneuvering them so they were laying on their sides. Stiles pulled Derek’s arm around him as he yawned.
“‘M tired.”
“Sleep baby. I’ll clean us up once my knot goes down.”
“Mkay. Hey, Derek?”
“Yeah?”
“I’m not a virgin anymore.”
Derek laughed. “No, you’re not. Go to sleep, Stiles.”
***
Stiles wasn’t sure what woke him up the next morning, but he realized that Derek wasn’t in the bed. Opening his eyes, he started to freak out for a moment before he realized the sun shining through the window was probably what woke him up. And possibly the reason for Derek not being in bed with him. He stretched and let out a small groan. He was sore. It made him grin. He was sore in the best way possible.
“Pain?”
Stiles turned to see Derek coming into the room with a tray of food. Stiles noticed he was only wearing a pair of sweats. “Breakfast in bed?”
Derek shrugged as he climbed into the bed with the tray. “You okay? You in pain?”
“Not really. I’m sore, but that’s to be expected, right?”
“Yeah.”
They ate in silence for a bit before Stiles shook his head. “Derek, I’m fine. Really. Ten out of ten, the best sex ever and I can’t wait to do it again.”
Derek rolled his eyes. “You’re insane.”
Stiles stuck out his tongue. “Have you heard from dad and Melissa?”
“So mature, Stiles. Yeah, your dad called while you were still sleeping. He said that he’ll be bringing Mila home in an hour.”
“We have a whole hour child-free. What should we do with our time?” Stiles wiggled his eyebrows.
“Oh my god, you’re going to be insatiable aren’t you? Finish your breakfast.”
Stiles grinned. “You didn’t exactly say no.”
Derek let out a sigh. “No, Stiles. We don’t have time.”
“What are you talking about? We have a whole hour.”
“I will knot you.”
“Still not seeing an issue,” Stiles glared.
“We don’t know how long it’ll take and just because your dad said they were coming in an hour doesn’t mean-”
Derek was cut off when the doorbell rang. Stiles glared. Derek laughed and kissed him.
“Tonight baby. I’m going to rock your world.”
He climbed off the bed and headed downstairs to open the door for Mila and Noah.
“DADDY!!”
“Hey princess!” Derek picked Mila up. “Did you have fun with grandpa?”
Mila nodded and proceeded to tell her father everything they did. Derek chuckled before looking at Noah.
“I hope she didn’t give you too much of an issue.”
“Not at all. She was a perfect princess. Where’s Stiles?”
Just before Derek could answer, Stiles came down the stairs in his sleep shorts and a t-shirt. Noah shook his head.
“If I didn’t know any better, I would’ve said you boys just woke up.”
“Nah, we’ve been up for a while. Hey sweetheart,” Stiles smiled.
“Papa!” Mila flailed trying to get over to Stiles.
Both Noah and Derek laughed. “Yup. She is definitely your child, Stiles,” Noah said.
Stiles stuck his tongue out. “Don’t you have somewhere to be, old man?”
“Who you calling old man? I can still kick your butt.” Noah made like he was going to go after Stiles.
Stiles yelped and jumped back. “Save me Mila! Grandpa’s going to get me!”
Mila pointed a finger at Noah. “B’nise Gappa! No h’t Papa!”
Noah chuckled. “I’m sorry Mila. I’ll be nice to papa.”
Stiles started to stick his tongue out at his father, but Mila turned in his arms and fixed him with a serious look. “B’nise papa!”
Stiles gave such a shocked look that both Noah and Derek laughed. Noah patted his son’s shoulder.
“Well, I’ll see you guys later. You guys still coming over for dinner, right?”
Derek nodded. “We’ll be there.”
It was something they started over a month or so ago. Where Noah made sure that he had at least one night a week off and Derek, Stiles, and Mila would go over to his place for dinner. It started as a way for Noah to truly get to know Derek while making sure his son was doing okay, especially after all the stuff Scott did to him, but then it formed into a full on family thing.
Stiles closed the door after his father and nuzzled Mila, “How about we head to the park?”
“Yay!” Mila screamed in his ear.
Stiles set Mila down and after he and Derek showered and dressed, the three of them headed to the park where they spent all afternoon.
