As dawn approached and Stiles began to feel an itch on his skin, Peter lowered all the blinds in the apartment and it was left in complete darkness. They could both still see in the dark, their eyes glowing. Peter was staring at him with a fascinated expression. Stiles realized that he hadn't seen his own eyes glowing yet. He got up and looked at himself in the mirror on the dresser. Red. Like blood, like alpha.

"A-am I an alpha?" he asked in a whisper with some hesitation.

"No, there is no such hierarchy among vampires. They all have those same eyes, although that doesn't make them any less beautiful."

Stiles' eyes glowed brighter for an instant. Peter's heart didn't waver on a single word, it never did.

"I'm going to put a curtain in the room to make sure no light gets in, and I'll put them in the rest of the apartment tomorrow."

Peter was gone before he could even think of anything to say. Stiles wasn't good at accepting compliments, he wasn't used to it, and it was even more difficult with someone like Peter who rarely spoke kind words to others.

The blinds were thick and thick enough to block out the light, but Peter made sure of it by nailing a thick cloth over the window.

"Are you sleepy or tired?" Peter asked.

Stiles frowned thoughtfully. He didn't really feel tired like he normally would, he hadn't felt the usual adrenaline drop after a fight nor did his eyes bother him after spending hours researching on the computer. He hadn't even yawned (he never thought he'd miss yawning), but his body felt less energetic, like he had to try harder to do anything. It was a very subtle sensation, but it seemed to get stronger as the sun raised.

"I think... something like that? The daylight may affect me." It was hard to explain when even he didn't understand it.

"It may slow down your system. Do you want me to let you rest?"

Stiles looked down and bit his lip. He wasn't sure if he would fall asleep and didn't want to be left alone with his own mind all day, but he didn't want to force Peter to sleep during the day either. He didn't want Peter to change his routine because of his new situation.

"I can stay, too," Peter suggested at his hesitation, "if it's okay with you to sleep with me."

"If you sleep during the day, you'll become nocturnal."

Peter smirked and started to open the bed.

"I've been nocturnal most of my life, it won't be a problem."

They got into bed and at first Stiles tried to stay to one side, but it took him barely a few minutes to find himself snuggled next to Peter. It was ridiculous trying to pretend at this point. Besides, it was too tempting. The wolf's heat seemed even more intense now than before, perhaps because his own body had grown colder. It was like hugging a stove. A stove that smelled really good. He just wanted to be surrounded by that smell, it was comforting, warm and fresh, like earth and forest and rain, and at the same time it made his mouth water, all that blood under his skin, so delicious and full of power.

He felt saliva slide from the corner of his lips, and for a moment he thought he was drooling in his sleep. Until he realized that his mouth was stuck to Peter's neck like a leech as he licked and sucked, soaking the skin with his saliva. He jerked away and almost flew out of bed except for Peter's hand grabbing his calf as he was about to fall.

"Oh god, oh god, I'm so sorry, oh my god," he said over and over again, still stunned.

"Stiles, Stiles, calm down. Nothing happened." He tried to hide it, but his lips curved into a smile.

"But, but I have..."

"You haven't even bitten me, you were just sucking, and if it had bothered me I'd have stopped you when you started half an hour ago."

"Oh god!" Stiles covered his face with both hands. He had been sucking on Peter's neck for half an hour! And from the red mark that had only just begun to fade, he hadn't been very kind.

"It's your instincts, it's nothing bad," Peter assured him, squeezing his leg.

"What an instinct," he sighed. He frowned when a strange idea occurred to him. "If I bit you, would you turn? Would you be a vampire-werewolf or a werewolf-vampire? Vampire-wolf or were-?"

"It's getting dark, are you hungry?" Peter interrupted him, getting up from the bed.

"Hey, I'm serious, I don't want to turn you, uh..." Stiles glanced at the erection in Peter's pants and was thankful that he couldn't blush anymore. It was natural, a very common reaction, and it had nothing to do with him sucking on his neck for half an hour. Right?

"You can't turn someone who isn't human to begin with, and from what I know, you can't turn a human with a bite either. I think you'd have to give them your own blood to drink too. And speaking of blood, are you hungry?" he repeated.

"Mm... M-maybe. Though it doesn't feel like it always does." His stomach didn't growl, it was more of a feeling in his veins. He turned around when Peter opened the closet to change clothes.

"I'll go get some blood. I'll be right back." He squeezed his shoulder and walked out the door dressed as if he hadn't just woken up.

Hearing the door close, Stiles ventured out of the room. It hadn't gotten dark yet, the sky would probably still be orange-red outside, but the blinds didn't allow any light into the apartment. He checked his cell phone. He still had no calls or messages from his father. He spent the next hour writing messages to his professors and the university to let them know that he would have to leave the course for personal reasons. After a year and a half of master's degree, he really regretted dropping out. If it weren't for the internship, he might finish it, but it was impossible that way.

He smelled the blood before the door opened. His body reacted without thinking. He jumped off the couch and landed about thirteen feet away, near the front door. Peter came in with a thermic bag in hand.

"Anxious?" he asked when he saw Stiles waiting for him there.

"Just, um..." He twisted the hem of his shirt between his hands, maybe he was hungrier than he thought.

"It's okay, it's natural. Let's go to the bathroom, I don't want blood on the floor, again."

Peter guided him to the bathroom with the broken screen with one hand on his back. There was no longer a trace of the crystal shards.

"I've brought two bags, I can go get more if you need it." He put the thermal bag next to the sink and took out a bag of blood like the one they would give you for a transfusion. "It's from the most common group so that they won't notice. I don't know if vampires differentiate between blood groups, but we can check it in the future."

Stiles took the bag in his hands and looked at it doubtfully as his mouth salivated.

"How..."

"Just let yourself go," he whispered, rubbing his back. It was a relief to have him by his side and to know that he would not look at him like a monster if he drank that blood.

He couldn't hold back anymore, he plunged his fangs (how did he get them out?) into the plastic bag. Blood flowed into his mouth, and it was as if colored fireworks exploded in his mind. He closed his eyes and moaned as he swallowed the cold liquid eagerly. Peter was holding him around the waist with one arm because his body was wobbling as if his legs were failing him. Stiles leaned against him with his head thrown back as he devoured every last drop of his new food and a trickle of blood slid from the corner of his mouth.

When the bag was empty, he dropped it and enjoyed the taste that remained in his mouth. He leaned against Peter and let his head fall on his shoulder. He took a deep breath and that delicious smell mixed with the taste of blood. He felt his body burning even though the blood had been cold.

"Do you want the other bag?"

He was barely aware of it when Peter spoke to him, but he shook his head. It wasn't more blood what he wanted now. He raised his head and kissed Peter without hesitation, just hungry. A growl vibrated in the wolf's chest, and Stiles would have laughed if he weren't so busy. He took his face with both hands and kissed him with the same eagerness with which he had drunk the blood. Peter responded with the same enthusiasm, guiding the kiss to something more coherent. Stiles moaned when Peter grabbed his hips with both hands, but then complained when those same hands pushed him away.

"...?" He forgot to breathe and forced himself to take a breath. "Peter?"

"Stiles," Peter exerted a little more force when Stiles tried to kiss him again, "I need to know you don't do this blood-induced."

Stiles frowned and shook his head to clear his thoughts.

"Uh... No, yeah... um... it made me really horny, but it didn't make me kiss you. If it wasn't you, I wouldn't have." He would have gone to jerk off in the bedroom, but he wouldn't have kissed just anyone.

"That's good enough for me."

Peter resumed the kiss, and Stiles wrapped his arms around his neck. The wolf pulled him closer, and Stiles could feel his erection against his pubis. The boy moved his hips against him and Peter grunted, but this time instead of pushing him away, Peter grabbed his buttocks and lifted him up. Stiles gasped between his lips and wrapped his legs around him. Peter led him into the living room and laid him on the couch, pressing his body against him. Stiles moaned, pulling him even closer with his legs. He was glad he didn't have to breathe because he didn't want that kiss to end. Why hadn't he done it before? The wolf pressed his erection against him, and Stiles squirmed with a needy moan. He couldn't believe Peter had gotten so hard for him when they had just kissed each other.

Then he felt Peter's hand slide under his shirt and it was like diving into an icy bath. His body tensed, and he grasped Peter's wrist with not quite human strength. Peter froze instantly. He looked at him worriedly, sitting up until he wasn't pressing against the boy anymore.

"Tell me what you need," he said calmly, waiting patiently for him to clear his mind.

Stiles forced himself to breathe because for some reason it helped calm him down. He wasn't sure what he needed, but he did know what the damn problem was.

"Time out," he asked.

"Okay." Peter pulled away and helped him up. He didn't seem at all annoyed that he had suddenly spoiled the mood, he just seemed concerned. "I think we should talk before we get on with this. I don't want you to feel uncomfortable or to do anything to hurt you at any time."

"Why now? I mean, is it my body? Before you didn't... Ugh!" He tugged at his hair as he shook his head. Why did he have to lose his eloquence at times like this?

"Let's cool down for a bit," Peter said, getting up from the sofa.

"Do you like me now because my body has changed?" The idea was terrifying, but he had to know.

Peter looked at him with a soft expression on his face. It was strange to see him like this, he never showed himself like that in front of others.

"Stiles, if you had heightened senses before, you'd have realized that I've been interested in you since before it was legal. My nephew threatened me more than once because of the way I smelled when you were around. If your friends had a minimum control over their abilities, they'd have noticed as well."

Stiles felt something warm inside him. It was a relief to know that Peter wasn't just attracted to his current body. He knew Peter wouldn't do something like that, but he needed to hear it.

"Okay, then we can go on."

He got up and walked over to Peter, resuming his position with his arms around Peter's neck and his lips against his. Peter allowed the kiss for a few seconds before pulling away from him a little. Stiles complained, trying to chase his lips.

"First we need to talk about what can make you feel bad."

Stiles huffed. He didn't want to think about it, he would only get depressed.

"Can't we just... kiss and rub until we cum and talk about it some other time?" he asked a little frustrated.

Peter smirked and leaned down to kiss his neck, and Stiles tilted his head without being asked.

"Okay," he sighed as if it were a great effort.

Stiles pulled him back onto the couch, and this time he was the one on top. Peter grabbed him by the ass almost automatically, and Stiles moved his hips against him, causing them both to moan. They continued kissing as Stiles wiggled and Peter encouraged him by squeezing his buttocks. They had to talk before they even took off their clothes, but rubbing against that muscular body and Peter's wonderful kissing skills were enough at the moment. His entire body was warm, and he could already hear the wetness in his boxers as his sex parted as it rubbed against Peter's erection. He could smell it along Peter's pre-cum and what he guessed was his arousal. With his new senses it was overwhelming, and it was difficult to focus on one thing, even his movements were uncoordinated, but it didn't matter because everything felt good.

A movement made him feel particularly good. A shock ran through his body, and Stiles sat up chasing that feeling. The wolf's eyes were glowing, his pupils dilated, and he was breathing heavily. He clenched his hands, almost claws, on his ass and it was evident that he was struggling to stay still and not thrust.

"Go ahead, go for it," Peter said hoarsely.

It was just what he was doing. Stiles could only think of cumming now that he had felt that. He clung to Peter's shirt and began to move his hips faster, feeling Peter's erection open his entrance. Damn pants! Why hadn't he taken them off? But now there was no time for that, he was going to...

He threw his head back and moaned, pressing against Peter without moving anymore. Peter grabbed him by the hips and started thrusting, stimulating his orgasm, making it stronger and longer as he came in his pants. Stiles fell onto the wolf and they both stayed still as they enjoyed the effects of their respective orgasms. Peter was panting, and his heart was beating fast. Stiles would be in the same situation if it weren't for his heart no longer beating and not needing to breathe. Still, he could feel the phantom beating of his heart through his veins.

Stiles didn't move from there, why would he? He felt too good lying there, and Peter didn't seem upset at all.

"I should put the curtains up for the daylight," Peter commented, absently forming constellations on his back with his fingers. "Or cook something."

Stiles tried to get up, but Peter stopped him with an arm around him and groaned. Stiles chuckled and buried his face in his neck.

"You don't need to put the curtains, I think we'd better go back to Beacon Hills," he whispered without lifting his head.

"Are you sure?"

"I want to be able to practice with my new skills, and what better place to do it than in the woods right behind the house. Besides, there's no point in staying here if I can't work or study." He wanted a quieter place to get out and adjust to his new senses and powers, and now Beacon Hills was the quiet place it seemed to be.

"Okay. I don't want us to risk dawn, so we'll get going tomorrow as soon as it gets dark."

Stiles nodded with a hum and settled on Peter. The wolf's face wrinkled as he felt the semen drying on his pants, but he was too comfortable to say anything and spoil the moment.

After a while, Peter made something for lunch (or dinner or whatever). Another thing Stiles was sorry to lose. Not even its smell attracted him, although he was sure Peter was a great cook. He checked his cell phone while he watched him eat, but there was still nothing. His father had likely seen the message when he couldn't respond and then forgot about it.

They lay in bed to watch Netflix, but neither paid attention to the movie they had chosen when Peter asked if he had thought about his red lines. Stiles complained, but Peter insisted.

"It's important, Stiles. I want to do things with you, I've wanted for a long time, and you get horny drinking blood." Stiles covered his face with his hands, he couldn't believe Peter had repeated it at a time like that. He had said it in the heat of the moment, but that was different. "I don't want you to feel bad for a second the next time."

Stiles huffed and sat up, beginning to fidget with his hands, twisting the hem of the shirt between them without looking at Peter at all.

"Don't mention names of..." he vaguely pointed at his crotch and chest, "my parts. Um... My chest... I was fine with it before, but now, I-I don't know..."

"You don't have to explain anything. It doesn't matter that you don't even understand it, it does matter how you feel," Peter told him, stroking his back without getting too close so as not to overwhelm him.

Stiles nodded and took a deep breath.

"Don't touch my chest or take off my shirt. Restricted area." He let it out so he didn't have time to hesitate in between. "The rest doesn't bother me, although I miss... um... doesn't matter.

"It does matter, Stiles, of course it does. Not only what you don't like, but also what makes you feel good."

Stiles bit his lower lip and ducked his head.

"You know what happens with this medication when, um, the clitoris enlarges until it's like a little..."

The volume of his voice dropped until Peter would not have been able to hear that last part if he hadn't had super hearing.

"Stiles," Peter leaned in and whispered into his ear with his hand slowly going down his back. "Would you like me to call it cock or similar names?"

Stiles moaned and clenched his thighs.

"Yes..." he answered almost without a voice.

"Let me suck your cock then."

Stiles would have made a pitiful sound if he hadn't been out of air. He nodded eagerly and brought his hands to his pants. He started to pull them down, and then Peter was kneeling between his legs. He gave him a quick kiss and pulled his pants down along with his boxers until he was naked from the waist down. Stiles felt the need to close his legs, but instead spread them apart. The growl he heard made him shudder. Peter was looking at him with a hungry expression, his eyes too blue to be human.

The wolf placed both hands on his knees and kissed first one and then the other. He moved down his thighs, alternating kisses between one and the other, biting gently on the inside, only brushing the skin with his teeth, making his legs tremble. Stiles spread his legs even further so he would get to the point.

"Tell me what you want, sweetheart," Peter said in a voice that almost sounded like a growl, his lips so close but still...

"Peter!"

"Let me hear it," he asked with a kiss on his pubis.

Stiles moved his hips with a groan when Peter pulled away from him.

"Nn... Please, Peter, suck my cock," he begged almost tearfully.

Without waiting a second, Peter leaned in and licked his entrance up and down. Stiles threw his head back with a moan and it bumped into the headboard, but he paid no attention to it. Peter grunted at the taste of his hot, wet sex and lifted his legs by his thighs to begin to eat him eagerly. Stiles moaned loudly as he licked his cock, and Peter focused on that spot.

"Yes, yes, Peter, god, there," he moaned as he unconsciously moved his hips for more even though Peter held him against the bed.

An intense sensation began to form in his sex and when Peter nibbled gently on his cock, that sensation suddenly exploded throughout his body in wave after wave. He stopped making sounds because his mind was simply too busy with his orgasm to think about breathing. His legs twitched and trembled as Peter continued to suck him until the orgasm slowly faded away.

Stiles opened his eyes and saw Peter beside him, grinning like the cat that got the cream, his goatee glistening with his fluids. Stiles couldn't even be upset, the wolf had the right to be proud. He saw the noticeable bulge in his pants, but Peter didn't seem in a hurry to deal with it.

"Everything okay?" he asked, stroking his face with two fingers.

"Are you looking for compliments?" Stiles asked with a laugh.

"I think my work deserves it," he replied with his head held high.

"Mhmm, you did a good job. Although I can think of something better to make up for you." He slid a suggestive hand up his thigh. He didn't realize that his eyes were glowing.

"Only if you really want to do it," Peter replied, although his desire was more than evident.

"Peter, I don't need to breathe. I can have your cock down my throat as long as I want."

Peter's eyes flashed neon.

"That," he cleared his throat because his voice sounded almost like a growl. "Yes, okay."

Stiles grinned like the Cheshire cat and turned quickly to kneel between his legs in an almost identical position to where Peter had just been. The fabric of his pants creaked when Peter took them off, he was losing control a bit.

"Have you done this before?" the wolf asked.

Stiles raised an eyebrow at him. Why wasn't he letting him get on with it already?

"I just want to know if I should guide you or not."

"Pfft... Well, let's say I have practice with various objects, and I've also done it with the occasional boy. It's really the only thing I've done, and I've been told I'm pretty good at it," he said a bit embarrassed. Not because he had sucked off a few guys, but because that had been the only thing he had done, he hadn't been able to go for more.

"All yours, then," Peter said, pulling down his boxers.

God, he was... big. Nothing monstrous or off the charts, but... enough to make him salivate. Stiles grabbed it with one hand and didn't hesitate for a second to lick it from bottom to top and put it in his mouth slowly and to the bottom.

"Fuck, Stiles," Peter grabbed his hair without realizing it, just for an instant before releasing it.

Stiles grabbed his hand when he pulled it away and placed it back on his head. He swallowed around his cock, and Peter shuddered. Fuck, it felt good, so tight and warm, so wet. But it was not enough. He could spend hours in there, but not when he so desperately needed to come.

"Stiles, please, I can't... I need you to move," he asked impatiently.

Stiles opened his eyes and mumbled an apology without removing his cock from his mouth. He had forgotten about that. He began to move, using his hand too. He ran his tongue down the shaft as his saliva dripped to the base. Giving head has never been easier. Peter began to breathe heavily, the boy was too skilled with his tongue. Maybe he did have oral fixation as he had suspected. Peter grabbed his hair and shook his hips even though he tried to stay still, but Stiles didn't seem to mind.

"I'm gonna... Stiles..."

He tried to warn him, but Stiles hummed and Peter couldn't take it anymore. He came deep in his throat, the muscles contracting around him, milking him. Stiles swallowed it all without flinching and didn't pull away when he finished. Instead, Stiles slid his cock deep into his throat and settled between Peter's legs with his head resting on his thigh. It was obstructing his airway, but he no longer needed to breathe so he could stay that way for hours without problems. He didn't know why, but it relaxed him, it always had. Peter stroked his hair. He could get hard again just seeing him so comfortable with his cock in his mouth.

"Do you want me to play the movie again?" he asked. They had both forgotten about it.

Stiles nodded slightly. Peter reached for the computer without bothering the boy much and placed it where he could see it too, although it didn't really matter, Stiles didn't last long with his eyes open.
