In which Isaac is turned into a baby by a witch and it is Derek and Stiles' responsibility to watch him... But mostly Derek's because stiles has a bad reputation of losing people, like when Scott first transformed into a werewolf.
————————————————
Stiles was making breakfast for Isaac, Derek, and himself, while Derek had just woken up with a persistent morning wood.
Derek rose from his bed and heard Stiles cooking from the kitchen. He lazily walked up to greet him, nuzzling his head in the nook of his neck and placed a few kisses but tried his hardest not to press his hard member onto Stiles, he was far too shy to do that. They have only been dating for a few months and Derek was really cautious seeing as the other women he had sex with were very bad people. The farthest they got was an extremely heated make out session that ended with Derek running away.

Flashback
—————
They were both on the couch watching a movie with Stiles sitting on Dereks lap, snuggled into his chest. Then suddenly Stiles began to place small kisses on his jaw, nibbling here and there to get his attention. Derek didn't acknowledge Stiles hoping he would stop...but he didn't. Instead of stopping all Stiles did was dive in for a kiss, which Derek could not ignore, he couldn't help but kiss him back. Their lips moved together and Derek was quick to move the kiss into something heavier by pressing his tongue past his lips.
It wasn't their first kiss, that happened before they even started dating. It was then the Kanima paralyzed Derek and Stiles had to keep Derek alive. After that traumatic experience, when Derek was no longer numb, he dove in to kiss stiles and afterwards he told him to forget about it and ran away.
The kiss continued for about 2 minutes with Derek gripping his hands into Stiles' waist and Stiles rubbing his hands across Derek's chest and sides. Derek let out breathy groans that where barely audible. While Stiles was very talkative with his moans, which didn't surprise Derek one bit.
3 minutes into the kiss Stiles began to slowly rock his hips into Derek and he started to reach for his jeans so that he could unzip them. But Derek let out a growl and pushed Stiles off of him as he ran away with growls spilling out of his mouth. Stiles sighed and shoved a pillow on his lap to hid the hard on that Derek gave him.

After that experience Stiles gave up hope that he will lose his virginity to Derek any time soon.
Stiles jumped a little when he felt Derek kiss his neck and his arms wrap around his waist.
Derek was hella into cuddling and showing affection he just had a hard time with the sexual department, that doesn't mean he has a hard time getting it up cause that is far from true. Even though they didn't have sex Stiles could still feel Derek's hard on when they snuggle together. The first time Stiles pressed his hips back against Derek which ended in his hissing and letting go of Stiles move to the other side of the bed. He then learned not to pressure Derek at all.
"Whatcha making?", Derek mumbled into his neck, which caused Stiles to shiver but he ignored it.
" Bacon, eggs, and pancakes.", Stiles replied and moved his head so that he could give Derek a little peck. Derek moved to let their lips touch for a moment but suddenly some grease from the bacon flew from the pan and burned Stiles on the arm. Stiles gasped and shoved himself back onto Derek which by his surprise Derek was sporting a major hard on, Stiles could practically feel it throbbing beneath his ass. Derek's grip on Stiles tightened so that Stiles could not move, but Stiles' ass was still pressed firmly on Derek.
"I'm sorry. Please don't move.", Derek mumbled from still inside his neck. Stiles was careful not to move, to not drive Derek away. Kinda like an animal. Derek let one of his famous breathy groans that shows how turned on he is. He then continued, "It's just been so long since-..." Derek let out a shaky breath
"How long?"
"1 and a half- almost 2 years. I just want...", Derek trailed off, he really is such a shy guy.
"Release?", Stiles offered, and Derek let out a chocked chuckle as he nodded in his neck. Stiles could tell that he was silently suffering, especially for such a big guy like him. Stiles spoke again but more cautious his time," Y'know, Derek. It's okay to enjoy yourself, with me. Especially with me."
Derek suddenly started to slowly rock his hips into Stiles as he replied to him," I want-... I really want that. But-..."
" I know... But you can trust me, just let go.", Stiles pushed a little this time. Derek nodded in his neck and his rocking started to turn into actually thrusting into his clothed behind.
Derek turned them both around to where Stiles was bracing himself on the island in the center of the kitchen. Stiles was slightly bent over the island and Derek was now at a moderate thrusting pace. Stiles reached inside his shorts and began jerking off his own dick at the same speed of Derek's thrusting.
Derek stayed at this spread for about a minute and Stiles couldn't take it anymore," P-please FA-ster Der-e-ek."
Derek let out a growl and gripped onto Stiles' hips impossibly tighter as he picked up the speed. Stiles was surprised that he actually listened, so he tried even further," Derek, I want- I want... T-tou-ch me."
He brought he hand around Stiles and gripped his smaller dick. Derek hunched over Stiles and pressed his fangs into his neck without drawing blood as he jerked Stiles off at a faster speed than his thrust.
Stiles couldn't help but moan and become impossibly closer to the edge. He rolled his hips back into Derek with hard, firm rocks.
Derek moaned in Stiles' ear," I-want..."
"What do you want?"
Derek growled in his ear which shook his whole body along with Derek's. "I want to cum on your skin and rub it into your body so that everyone can smell me on you and know who you belong to."
Stiles released a scream like moan as he jerked his member as fast as he could and cum came shooting onto the kitchen floor and island. After wards Stiles tried his best with his hips to push Derek to come.
Derek stopped his thrust into Stiles ass and pulled his shorts and boxers down to reveal Stiles' round, soft ass. He removed his member from his sweatpants and gave it harsh strokes and came all over Stiles ass while moaning very loudly," Fuck, Fuck, Fuck, Fuck. Stiles', I'm about to cum on your ass. I want it to leak into your tight little hole."
Stiles would have probably came a second time if he wasn't so warn. Derek slumped against Stiles backside to recover. Which took about 5 seconds seeing that he's a werewolf. While stiles was still recovering Derek got onto his knees and began to rub in the cum that Derek just got on him. Derek used some of his cum and worked it inside of his hole. He pressed his fingers inside of Stiles' and watched him squirm. Derek's dick was quick to raise to life again.
"Stiles, I want to fuck you."
Stiles moaned and rocked back into Derek's fingers. Derek growled and shoved another finger into Stiles hole, which was already stretched. "Have you been fingering yourself?"
Stiles moaned as he nodded," Y-yes. I used the really big didlos to prepare for your dick."
"Good boy.", Derek groaned as he applied another finger. Now he began to test different angles. After a minute of that Stiles suddenly jerked and he went dead silent, this whole time he was moaning but now he was dead silent besides the whimper he let out. Derek tried the same angle and Stiles breath hitched but he was still silent. "Derek, I want you in me-... like now."
Derek groaned and he removed his fingers and pressed the tip of his cock against Stiles' stretched hole. He spent about a minute teasing Stiles by only thrusting the tip in him but Derek began to push more of himself inside Stiles.
But then it happened.
Ring Ring Ring Ring Ring Ring
The fire alarm went off and the sprinklers began to turn on. They had completely forgotten about to food that Stiles was cooking and Derek was too wrapped up in fucking Stiles to notice anything else. They could also hear Isaac starting to scream and cry in the other room.
"Fucking Shit.", Derek groaned and removed himself from Stiles' welcoming hole. He tucked himself back inside his sweatpants and ordered,"You go wait outside for the fire truck to come. I'll go get Isaac."

" What exactly happened here?", the fireman asked Stiles as Derek was in the car trying to calm down baby Isaac.
" I was making breakfast for Isaac, Derek, and me. Then Derek came down stairs and we both got-...distracted. So 15 minutes later we nearly burned the house down.", Stiles rambled but tried not to say too much.
"Is Isaac your son?", The fireman asked.
Stiles was thrown by this question but didn't want to come off as suspicious," Yes, Me and Derek adopted him."
The fireman nodded trying not to come off as homophobic.

They had to stay in a hotel that night seeing as everything was soaked. Also Scott and Kira took baby Isaac away seeing as they nearly burned the house down. Stiles was very concerned about Derek though. Seeing as the house nearly burned down while they were about to have sex, sounds familiar right.
Stiles walked out of the bathroom after a long hot shower and jumped on the bed on top of Derek. "Are you okay?"
Derek put down the book that he bought earlier that day seeing as most of the books in his house where soaked. "I'm okay Stiles." He said as he placed a kiss on his cheek.
"Your not scared, you will have sex with me one day?", Stiles said as he stared at him with hopeful doe eyes.
"No I'm not scared and I will have sex with you." Stiles got really excited seeing as Derek didn't say when. "Just not right now."
Stiles frowned and flopped to the other side of the bed a she mumbled," To think, not 5 hours ago you were inside of me. I was so close to losing my stupid virginity."
Derek chuckled and snuggled up next to him and spoke," Your virginity is not stupid and if it wasn't for Isaac I would have still fucked you while the sprinklers where on and have those fireman watch me take what is mine."
Stiles shivered and felt his dick rise to life again with that mental image. Stiles groaned and attempted to get up from the bed," I'm gonna go jerk off in the bathroom."
Derek yanked Stiles right back down into the bed," No!", Derek growled,"Do it right here. Show me how hard I make you. Show me how your body shivers when you cum for me. I want to see it all."
Stiles moaned and shoved down his pants down for Derek to see what he did to him. "I swear, if someone pulls a fire alarm I'm gonna scream."
They both chuckled at that.

After the spell wore off of Isaac Stiles mumbled at him," Your the reason I'm still a virgin."
Derek burst into laughter and Isaac stared at them both with wide eyes.
