TEEN WOLF - MPREG BIG BANG - A Legend of a Lonely Boy - Part Five

[bunnymaccool]

~*~

Once the pack had reunited and Derek had calmed his betas down by participating in a snuggle pile of epic proportions… he felt a little silly about his outburst. Stiles had said it was just his hormones being a bit off kilter and he really hoped that was the case. Because there was something he really, really wanted to do tonight.

The pack had returned to their homes around midnight, and the Sheriff had been called into the office for a few hours. Derek had excused himself to head upstairs for another shower. He was feeling sweated and filthy after his unplanned sprint across the town, so he was pretty sure there was nothing to be suspicious of. Once he was under the heat of the water and thoroughly clean, he eyed the shower gel with consideration. He’d been half hard for the duration of washing, just thinking about what he wanted to try.

Licking his lips with a small bout of nerves, he finally reached for the gel and poured a fairly large amount in his palm. Fuck. Okay. He could totally do this. Experimentation was the key to unlocking your sexual preferences, right? Coating his fingers liberally with the gel, he reached behind himself and rubbed them across his asshole. A small tickle of pleasure shot up his spine. He bit his lip in concentration as he pushed the tip of his index finger at the ring of muscle.

It slipped inside a lot easier than he thought it would and he released his lip with a small gasp. So far so good. There wasn’t any pain yet. Just a really strange pressure and a little bit of burn. Nothing he couldn’t handle. Nothing like what Peter had done. Pushing the digit in further, he wiggled it back and forth feeling the relative smoothness of his inner walls. The back of his finger brushed over what must have been his prostate, because a small jolt of electric pleasure made him spasm and tilt forward towards the tiled wall of the shower. Well, that was definitely a PRO on the gay sex column.

He tried to shift his finger to hit the gland more precisely, but the digit was facing the wrong way and the angle was just bad. Glancing down at the tub, Derek took a second to ponder if he was actually about to spread-eagle in the Stilinski’s bathtub and finger fuck himself, before he was moving to do it. He toed at the stopper to close it so the bath would fill and flicked down the shower pull so that hot water was pouring out of the main faucet.

The alpha sat down in the rapidly filling tub and settled back against the porcelain. While he waited for the bath to fill, he tugged on his cock a few times to keep it interested in the proceedings. Finally the water reached his chest and he used his feet to turn off the knobs. The instant quiet of the room suddenly made him feel even more nervous about what he was going to do. With a deep, calming breath he shifted one leg up to press his foot against the wall of the shower. For a second he couldn’t figure out what to do with his other leg, until he just threw it over the rim of the tub, free of the water but hidden by the shower curtain.

He took another deep breath. Coated his fingers again with the gel still slicking his palm. Then reached down into the water and pushed the first digit right back in. The slide was much easier and the angle was holy shit so much fucking better. Tilting his hips up and pushing his finger down, the soft pad of his fingertip brushed right across his prostate and he gasped. So, so much better.

Working the finger in and out of his body had his neck arching back against the tub and his toes curling unconsciously. If one finger was good. Might as well try two, right? Pushing in the second brought more of the burn, but the increase in pressure was … nice. He felt more stretched, more full. He keened softly as he increased the speed of the penetrating push and pull.

There was a polite tap on the bond just as Stiles rapped his knuckles on the still broken door to the bathroom.

Derek froze. Fingers pushed up inside him to the knuckle.

The broken door shifted open just enough for the teen to apparently poke his head in.

“Oh! You’re taking a bath instead? I was wondering what had gotten you all sunshine and rainbows suddenly.”

At the sound of his mate’s voice, Derek’s cock managed to go even harder and his balls tucked up tight. He sent a prayer of thanks to every fucking deity he could think of that he’d remembered to close the shower curtains. And that the Stilinski’s hadn’t purchased any of those see-through vinyl pieces of shit.

“Bet that feels really good, huh?”

Derek nearly fucking choked on his own tongue.

“Hot bath will probably work a miracle on your back.”

No matter the sort of affection the alpha held for the teen… he just really wanted Stiles to leave the fucking room. Like, five minutes ago.

“Derek? You okay?”

Oh God. This was punishment for something, wasn’t it? He mugged a bus of nuns or something in a past life, hadn’t he? He shifted in the tub, which was a mistake because that caused his fingers to press right up against his sweet spot hard and fireworks burst across his eyes for a second. His voice came out warbled and totally unconvincing.

“I’m fine.”

Stiles was quiet for several seconds and Derek just couldn’t keep still for any longer. He wiggled his fingers teasingly before pulling them out and pushing them back in roughly. The werewolf bit straight into his lip until he tasted blood to keep himself silent.

“Oooookay. Well… try and relax. I’ll come check on you in a bit.”

Oh fuck. Oh fuck. Oh fuckfuckfuck. He was pistoning his fingers now, faster and faster, only just managing to keep his arm under water to deter sloshing sounds. His cock was going to blow any second, and Stiles still hadn’t left the fucking room.

“Mmhmm.”

It was the only response the alpha could manage, and it sounded strained even to his own ears, but he was fucking himself hard with his fingers now and he just … needed… to… come. Finally the teen shifted back out of the room and pulled the broken door shut behind him. Derek listened, panting harsh breaths into the water he had somehow slid deeper into, as his mate jogged down the steps and into the kitchen. He gripped his cock and only managed to strip himself twice before he was gone gone GONE.

His spine bowed forward with his orgasm until he was almost folded in half, eyes squeezed closed as little spots of light danced in the darkness. He spent himself in the warm water. Could feel the walls of his channel clenching at his fingers until he was done. With a soft sigh he relaxed back against the tub and carefully pulled his fingers from his body. His hole felt open. Hollow. Bereft. But strangely good.

If that was only two fingers, he wondered what a dick would feel like. The wider stretch. The deeper penetration. The alpha shuddered in anticipation. He was pretty sure it was safe to assume that he was totally in favor of future anal sex with his mate.

Yup.



When he finally crawled into bed in the early hours of the morning, he couldn’t fall asleep. The post orgasmic bliss had faded off and now he was left feeling a little embarrassed and a lot curious. What Peter had done had felt intrusive and painful and vile. What Derek had done to himself felt … raw, and open and on the edge of something that might be really amazing.

He tried to catalogue the differences of the two acts in his brain, but he was stumbling through it. Realistically, he understood that what had been forced upon him should probably result in him screaming and running for the hills at the mere thought of anal sex with someone. But the idea of that closeness, of giving himself over like that to someone he trusted and wanted, was desirable. It would be just as much a claiming act as the bonding, wouldn’t it? Maybe it would even help erase a little of the past experience. Paint it over with something better?

The alpha growled and flung the covers away as he stood from his bed. He just wasn’t going to manage to sleep tonight with all this shit running through his brain. As he turned to the door of his room, thinking about maybe going downstairs for a snack, he opened the connection with his mate … and a strong sense of arousal hit him smack in the face.

He froze. Stretched his senses to the room across the hall. Stiles was making soft little gasps and moans, muted, maybe into his pillow. There was a tale tell shifting of skin against skin and a heady scent of pre-cum in the air.

Mother fucker. He just wasn’t strong enough for this right now.

Derek was across the hall and locking the teen’s door behind himself before he really considered his actions. Stiles had gone still with shock as soon as the alpha had entered the room. In the darkness he could make out the younger man’s eyes, wide and embarrassed, and his hand disappearing beneath the waistband of his sleep shorts.

“D-Derek?”

The werewolf growled low and deep as he stalked across the room towards the bed. Stiles ripped his hand out of his pants and started to scoot upwards on the mattress, but Derek grabbed the teen’s ankles and yanked him back into a prone position. Stiles yelped, but it finished as a moan when the alpha proceeded to crawl up his body and press them together, chest to thigh.

“Oh my God.”

Those were the last words Derek allowed before he slammed his lips against his mate’s. Stiles’ mouth opened with a gasp and the alpha dove right in with everything he had. A rumbling purr of a noise was escaping him as he licked into his mate’s mouth, swept over his teeth, tasted the inside of his cheek. Stiles was breathing harshly through his nose, and his hands had wound themselves into Derek’s hair.

When he finally broke away, the younger man was panting ‘oh my god oh my god’ like a mantra in a soft whispered voice. Derek rumbled his pleasure as he leaned back and snagged the waistband of the teen’s shorts. Careful not to catch on the erection encased within, the alpha practically ripped the offending material from his mate’s body.

“H-holy shit!”

Derek grinned, and he knew he probably looked feral and crazed at the moment, but he just couldn’t help himself. The teen’s cock twitched under his scrutiny, so he figured the younger man probably didn’t mind so much. He leaned back further and promptly stripped off his own pajama bottoms. Stiles choked on air. Before he could second guess himself, Derek bent forward and licked a stripe straight up the underside of the teen’s dick, then quickly swallowed the whole thing down as far as he could go. The flavor of his mate exploded over his tongue and he purred in delight. Salty and bitter, but it didn’t matter, it didn’t matter at all. It was fucking delicious to his wolf.

Stiles was twitching and writhing across the mattress, fingers gripping the sheets in a strangled white-knuckled hold. Derek purred again, cock still in his mouth, and the teen nearly bucked right off the bed. The alpha chuckled to himself as he pulled off and began to paint tiny kitten licks across the head, dipping the tip of his tongue into the slit to gather the liquid there.

“Oh fuck! Oh Jesus! Oh fuck!”

The alpha hummed, continuing his teasing, as he reached behind himself and fingered at his hole. He was still a little stretched and loose from his bath earlier. It wasn’t near enough prep, but he didn’t give a shit. He just hoped that his mate would forgive him if this was taking it further than he was ready for. Derek just couldn’t help it. Something in him needed it desperately. He dove back down on Stile’s cock, getting it as spit-slick as he possibly could.

When he pulled off, the younger man was so dazed it took him a couple seconds to realize that Derek was up and kneeling, straddling the teen’s hips. He reached back to grasp the cock beneath him and Stile’s eyes flew wide, hands immediately snapping up to grasp Derek’s hips.

“What are you-”

His words cut off in a strangled groan as Derek positioned the head of his cock and spread his thighs further apart to slowly sink down. When the head popped through the first ring of muscle Derek mewled loudly. It was a hell of a lot more stretch than two fingers, and it burned burned burned … but he continued to press down. Head tilted back so that he was staring at the ceiling of Stile’s room, panting breaths and soft little mewls still escaping him.

When he was fully seated and Stiles was balls deep in, Derek whipped his arms forward to pull his mate’s hands from his hips and lace their fingers together, holding hands palm to palm. His head was still tipped back, and he’d closed his eyes to concentrate on the burn and the thick fullness inside. It was so different. It was so different from before. The pain was mixed with pleasure this time. The intimacy of the act actually meant something. At least… he hoped it did.

Derek forced himself to look down and risk a glance at his mate, who had been suspiciously silent through the act of penetration. Stiles looked … Stiles looked absolutely gorgeous. He was flushed everywhere and his eyes were dilated and almost luminous with arousal. His bottom lip was sucked into this mouth and he was biting into it’s plush softness. The alpha swiveled his hips experimentally and they both gasped sharply.

“Oh my God, Derek. Fuck…”

Derek hummed softly before pulled himself up slowly, until just the head of his mate’s cock was inside him, then he dropped down quickly, gravity plunging Stiles deeper than before. Both men groaned appreciatively at the resulting pleasure. Derek lifted himself again and again, dropping down faster and harder each time on Stiles’ dick. Sweat had broken out all over his body and he could feel rivulets of it running down his chest. Their hands were still clasped together, but now rested against the cut of Derek’s hips.

It wasn’t enough. It wasn’t enough, he wanted more. He wanted more, but he couldn’t figure out how to ask for it. How to get it. He clenched his eyes closed tightly and whined, high pitched and frantic. Stiles made a soft noise of comfort.

“I got you. I got you, Der.”

The teen shifted beneath him, pulling up his knees and planting his feet on the mattress. On Derek’s next downward plunge, Stiles thrust upwards with his hips and slammed into him. Derek fucking howled. That was what he wanted. That was what he needed. They built up a frantic pace, sounds of slapping skin in the room absolutely filthy to his ears. A thready keen had stuck itself in his throat, pitch raising and lowering as he was fucked harder and faster.

“Fuck! Oh my God! You’re so fucking beautiful. Derek, you’re so fucking…”

Stiles moaned through a particularly hard thrust, and the alpha could feel his mate getting closer to orgasm. He tried to clench tighter around his mate’s cock and was rewarded with a gasp. The younger man slammed up hard once more before he froze, thighs trembling against Derek’s ass, dick inside him spasming and shooting it’s load deep. Stiles’ feet slipped from their position as he collapsed flat on the bed again. Derek grunted when they landed, his mate’s cock still hard in his ass. He immediately began to swivel his hips in little figure eights, trying to reach his own orgasm before Stiles’ dick went too soft and slipped out.

The teen’s hands pulled away from his own, but before Derek could whimper his complaint they were both wound around his cock and pumping him frantically. One hand moved back to stroke across Derek’s balls and then tease at the rim that was still stretched open around Stiles’ wilting dick. The finger pushed inside and wiggled around until it brushed over his sweet spot. Derek gave a full body shiver at the sensation and Stiles grinned wide and lovely before he stroked hard over the bundle of nerves again.

Derek came so hard his world whited out for a bit. When he refocused he was folded over with his forehead resting in the middle of Stiles’ sweat-soaked chest. He groaned as he felt Stiles slowly pulling himself from Derek’s body. A funny tickle of liquid followed him out and it actually took Derek a moment to realize that it was his mate’s come dribbling out of his ass. Then the younger man was pushing at the alpha’s legs, which were still tucked up around his hips.

“Come on. That can’t be comfortable. Straighten out.”

Derek rolled off to the side, stretching to his full length. He worried for a brief second about the pressure he might have placed on his swollen belly, but a small push through to the spark of his daughter revealed that all was well. He sighed happily and nuzzled into the slope of his mate’s neck. Stiles chuckled softly.

“You really need to let me up so I can get us a washcloth.”

The alpha growled and wound his arms tightly around his mate. Stiles sighed.

“Are we going to talk about where this came from? Because I’m not complaining, believe you me, but I’m feeling a bit out of the loop here.”

As much as Derek wanted to drift off into sleep, Stiles was practically thrumming with excited energy. Groaning, the alpha lifted his head so he could look down at the teen. Stiles’ face was split nearly in two with a shit eating grin, and his face was flushed pink all the way to his ears. Derek grunted.

“What?”

Stiles fucking giggled in response.

“I just had sex. Oh my god, I just had sex… and it was AWESOME!”

Derek groaned again and face planted down into Stiles’ pillow.

“Please, you gotta give me a fist bump. Derek! You gotta give me a fist bump! Because I just lost my virginity and there’s no one else here to do it.”

Cursing his luck ten different ways the alpha slowly raised up his arm and made a weak fist. The teen bumped it with his own enthusiastically and then burst into excited giggles. He started to ramble off about something, maybe torturing Scott with descriptions and illustrations in retaliation for months of Allison over-share, but Derek just allowed the soft lilt of his mate’s voice to lull him into sleep.

He was dozing peacefully when Stiles’ phone chimed. The teen blindly groped around the table until he found it and proceed to fiddle with the damn thing. The light of it was bright in the darkened room, so Derek rolled over to his other side, presenting his back to his mate.

“Bank robbery last night. Dad says he’ll probably be in the office all day. Promised to eat somewhat healthy for lunch.”

Derek grunted in response.

“House to ourselves the whole day.”

He grunted again and was just beginning to drift off into sleep when the bed shifted. Warm lips were kissing at his shoulder as his mate tucked his body tightly up against his own. The hard shaft of the younger man’s dick rubbed along Derek’s ass and the werewolf’s breath hitched. Stiles’ hand drifted forward to cradle he mound of his belly as he nipped along the alpha’s neck.

“My baby. Mine.”

Derek whimpered at the possessiveness in the tone. Stiles slid his palm lower to grasp the alpha’s fattening cock and tug it a couple times, then moved further down to snatch Derek’s upper leg and pull it up and back until it was resting over Stile’s own. Leaving him feeling open and exposed to the air. Then those long fingers were rubbing against Derek’s hole and he was almost shaking in the teen’s grip. One digit pressed slowly inside and the alpha moaned.

“You’re still a little slick, but not enough.”

Jesus fucking shit. He had a feeling sex talk with Stiles was going to be a thing. Once the teen got some experience, got some confidence, Derek could just imagine the dirty filth that would probably poor from Stiles’ mouth. He whined when the finger withdrew, but his mate only shushed him as he arched his torso away to scrabble at the drawer of the bedside table. A couple things fell to the floor, but they were ignored for the familiar flick of a cap. A moment later there was a lube-slick finger pushing back inside and Derek bucked his hips.

Mouth and teeth had returned to nibbling and sucking at his neck and shoulder.

“Have you ever fingered yourself before, Derek?”

This kid was going to fucking kill him.

“You took a big chance last night with no prep. Could have hurt yourself.”

Kill him. No joke.

Derek groaned and rocked his hips in time with the finger fucking into him.

“L-last night… in th-… in the bath.”

Stiles froze.

“Where you fingering yourself while I was talking to you?”

Derek could only nod helplessly. His mate moaned and bucked against him. Two slick fingers suddenly thrust inside and the alpha cried out at the pressure. Stiles was grinding against his ass, dick leaving trails of moisture all over Derek’s skin.

“Is this why you were at my computer that day? I looked up the browser history. I couldn’t figure out why you would be interested… after what happened.”

Derek mewled and panted into the pillow.

“Wanted… wanted to be closer… to you.”

Stiles made a mewling sound of his own before pulling his fingers out and backing away. Derek whined at the loss, then realized that the teen was pushing him onto his back with one hand and slicking up his cock with the other. Derek immediately pulled his legs up and flung them over Stiles’ shoulders. The younger man laughed warmly at his eagerness so the alpha glared and snarled at him.

“Now, now … don’t be like that, momma.”

Derek growled at him, but it sputtered out to a whimper as Stiles slid home in one thrust.

“Fuck! If you’re going to be this tight every time I’m never going to build up any stamina.”

Stiles laughed, sweet and watery as he began to move. Derek dropped his legs to wrap them around the teen’s waist and hook his ankles. He couldn’t help the wicked little grin he knew must be on his face, but so far in his burgeoning sex life with Stiles it was completely different from every other experience he’d had. Not that there had been many. Kate had been rough and demanding, always making him feel dirty and used when it was over. Even when he fancied himself in love with her. The couple women he’d picked up in New York for a night or two and been simpering and clingy. Their smell and touch suffocated him.

And those were the sole experiences he’d had before … well … before.

Stiles changed the angle of his hips and picked up the pace. Derek purred happily and used his heels to help slam his mate in deeper with every thrust. The teen had been watching himself disappear into the alpha’s body, but at Derek’s happy noise he glanced up and smiled. Waggled his eyebrows ridiculously. Derek couldn’t stop the laughter that burst free from inside him. Couldn’t really even remember the last time he’d genuinely laughed out loud at all. His mate slowed his movements to reach forward and trace along Derek’s smile with his fingers.

“It’s stupid how fucking gorgeous you are. Totally unfair.”

Derek nipped at his fingers and Stiles laughed as he snatched his hand back. It was relaxed. It was good. It was fun. Sex with Stiles was fun. The alpha had never imagined it could be this way. He arched his back and rolled his head into this pillows, keeping half-lidded eyes on his mate’s reaction. Stiles cursed under his breath but watched with rapt attention. Derek began to roll his hips with the timing of Stiles’ thrusts and the teen groaned. He could feel his mate’s orgasm nearing, so he clenched his inner walls in aide, even though he wasn’t ready to come himself yet.

Stiles sucked in a gasp of air and let it out as a whine as he released inside Derek. The alpha couldn’t feel the spunk itself, just the odd pressure it created. Kind of made him feel like he needed to pee. Really weird, but nice. Stiles pulled himself out and immediately sat back on the bed, folding himself Indian style between Derek’s legs. Derek raised a questioning eyebrow as the younger man grabbed the alpha’s ankles and planted his feet on the mattress. Pushing them up toward Derek’s ass until his knees were prone in the air and his asshole felt like it was completely on display.

His mate grinned wickedly before pushing two fingers back inside and going straight for his prostate. Derek howled into the quiet house and the teen rubbed across the spot mercilessly again and again. The alpha flung his head back and forth in desperation, unable to even form any words in his mind to describe the feeling. He whined again and again until it was echoing off the walls and drowning out the soft words of encouragement his mate was mumbling at him.

Finally Stiles grasped his cock, tugged once, and Derek came like a fucking rocket. It splashed all up his abs and chest and his ass clamped down tight on Stiles’ fingers until he was through. With a soft sigh Derek relaxed back into the mattress feeling completely spent. He grunted when the younger man removed his fingers, but other than that light discomfort he was floating on cloud nine. Stiles helped him lay his legs down straight before bending over to kiss along Derek’s baby belly and lick up the come splattered across it. Derek rumbled a happy noise and the teen glanced up to meet his eyes.

Stiles smiled beautifully and scooted up to kiss him gently on the lips.

“A shower and clean sheets would probably be a really good idea before my dad gets home.”



To say that the shower was counter productive would be a fairly accurate description. Derek had barely managed to get the shampoo out of his hair before Stiles was dropping to his knees wanting a go at giving his first blowjob. Thankfully there were no teeth, but there was a lot of spit, several instances of gagging and an almost nosebleed when Derek came down his throat. But it was marginally successful.

The Sheriff honestly could not have picked a better day to get stuck at the office. Derek was pretty sure the man would have been just a mite uncomfortable with the fact that his son and the alpha were apparently getting months of sexual frustration out of their systems. Between the hair-trigger erection of a seventeen year old male and the hormonally hot-blooded libido of a pregnant werewolf … they went at it like rabbit’s the whole damn day.

At one point Derek had felt a couple of the betas drawing near, but at the time he was on his hands and knees in the middle of his bedroom getting pounded into from behind. He howled a warning to stay away, which probably sounded fucking ridiculous because the howl would hitch and break with each of Stiles’ thrusts. Did the job though. Whichever betas it was high-tailed it the fuck outta Dodge.

By the time dinner rolled around and the police cruiser pulled up on the driveway, they were completely spent. Luckily, the house had aired out some. Even though Derek could still smell the sex everywhere, he was pretty sure it was safe for human noses. They were sitting on the couch when John walked in. Correction. Stiles was sitting on the couch, Derek was stretched the length of it with his head in the teen’s lap and face smashed into his mate’s stomach. Pretending to be asleep. (It was the only way to keep the younger man from babbling about whatever show was currently on.)

Derek listened as the older man paused in the doorway, obviously noticing them, and quietly moved into the room. His voice was low and soft when he spoke.

“Hey, son. How’s he doing?”

Stiles grunted softly and leaned his head back to see his father.

“Hey, dad. Not too bad. Had a rough night, but we’re doing okay now.”

It took everything in him not to snort or snicker. Rough night. Yeah. Sure.

“Did you find out what happened at the doc’s?”

Stiles tensed beneath him. Derek feigned a soft sound of sleep before nuzzling further into the teen’s stomach. There was a chance his mate knew he was awake, and he wanted to make sure he knew Derek didn’t mind him speaking with his father. The teen licked his lips.

“It was … He just started thinking about how he got there. Who’s baby it was. Had a mini-melt down, but we talked it out.”

John made a humming sound of understanding before reaching down to pat Stiles gently on the head. After a moments hesitation, the older man bent forward to repeat the action on Derek. The alpha felt the burn of tears behind his eyes at the show of affection.

“It’ll all be okay, son. I just know it will.”

For the life of him, Derek couldn’t figure out which one of them the Sheriff meant those words for, but he really wanted them to be true.
