When Stiles pressed his lips against Theo's, Theo put his hand on the back of the other's head, pushing him closer. He slipped his tongue into the other's mouth, exchanging passion with the other.

As Stiles continued to suck Theo's face with sloppy open mouthed kisses, the chimera could feel the vampire's fangs that had popped out.

He began to tease Stiles, mouth leaving his and instead trailing kisses along his jaw and down to his neck. He nipped at the skin with blunted human teeth, sucking what would be hickeys if it weren't for supernatural healing. Theo then bit down a little bit harder, nothing too intense but enough to make Stiles moan. He responded by biting harder still, repeating this action a few times.

The chimera then drew back slightly, panting as he allowed his own fangs to reveal themselves. He brushed them lightly against the pale skin under them, careful not to break the skin, as if to ask for permission.

Stiles knew exactly what Theo was asking of him. He knew what it meant. Yet, despite the weight of it, Stiles didn't hesitate even for a moment. Instead, he titled his head back, a symbol of complete trust.

"Do it," he breathed.

"Are you sure?" Theo asked.

Theo was ready. He wanted to do it so badly that the anticipation was killing him, but he also knew. He knew that Stiles now had the night in the woods etched into his memory. The images and sensations of fangs viciously slicing into his skin would forever haunt him. Theo didn't want to recreate that, even if his instincts were screaming at him to claim Stiles.

Stiles completely understood the meaning behind those three words, but Theo wasn't her, and he felt completely safe. He didn't need to think about. He loved Theo. He trusted him.

"I'm yours," Stiles uttered, and that was enough for Theo to continue.

The chimera pierced the other's skin with his fangs, causing Stiles to gasp at the sensation. Instead of pulling away, though, he leaned up into where the other's mouth made contact with his neck. It didn't last long, with Theo quickly withdrawing his fangs and coming back up to look into Stiles' eyes with his own glowing yellow ones.

The marks healed almost instantly, but the sentiment was still the same: Stiles was his.

Stiles grabbed Theo's face before kissing him again, just wanting to feel him. He took Theo's bottom lip in between his front teeth, dragging it out until Theo chased him back into the kiss.

It was then Stiles' turn, and he began kissing Theo's neck. Unlike Theo who had kissed and sucked at the skin slowly, the contact that Stiles made was frenzied but still equal in intensity.

He used his vampire speed and strength to pin Theo against the wall in a flash before sinking fangs into his neck eagerly. Both boys moaned as Stiles' sharp fangs pierced the skin and Stiles began to suck hungrily, hips grinding his boner into Theo's as he did, beginning to feel almost high off of the combination of fresh life force and sexual tension.

After he felt satisfied and withdrew his fangs, he slowly dragged his tongue over the healing wounds, catching every spare drop of blood, continuing a little bit even after all of the blood was gone.

He then took a step back, allowing Theo to come up from the wall. As soon as Theo did this, Stiles' hands were at the bottom of his shirt, rolling it up before taking it over his head and throwing it across the room, eager to see and feel the other's bare skin. Theo then repeated the same action with Stiles.

Theo's hand moved from Stiles' abdomen lower, feeling the tent his pants. His fingers then came to the button, undoing it before pulling Stiles' jeans down. Stiles stepped out of them before removing his underwear and doing the same to Theo.

When the two were both completely naked, Stiles squeezed Theo's ass in his hands.

"Bend over for me," he whispered seductively in his ear.

Theo obeyed, making his way to the bed and doing as the vampire said.

Stiles spread Theo's cheeks apart before licking his asshole, causing Theo to release a soft moan. He continued this for a while, making Theo's asshole slick and wet before inserting two fingers, Theo biting down on his bottom lip and making more sounds of pleasure, prompting Stiles to slide in a third. He bit down on his bottom lip, revealing in the shudders caused by his touch as he fingered.

After a little while, Stiles removed his fingers, his hand stabling itself on the small of Theo's back.

"Stiles," Theo uttered, his voice needy.

He wanted — no, needed — Stiles to just touch him again. Those words were all it took for Stiles to penetrate Theo with his cock.

Theo gasped as Stiles began thrusting. He started off slow and gentle, Theo's hips moving in perfect rhythm with his.

He started moving faster, pounding his ass harder and harder, hands moving all over Theo's body as he did.

"Fuck," Theo gasped, hands grasping tightly onto the sheets as the sensation grew more and more intense.

Stiles didn't stop there though. He smirked sadistically before thrusting even faster, using his vampire speed, causing the chimera to scream wildly in pleasure. At that point, neither of them could help making loud and unapologetic sounds.

Theo held the bedding for dear life, knuckles turning white from the pressure. He panted loudly, unable to catch his breath, drowning in the intensity and roughness of the vampire inside him, fucking him harder and harder.

Theo was then even louder, voice booming from the dizzying orgasm. Stiles wasn't far behind him, cock violently spurting cum and filling the other boy up.

When Stiles was no longer inside of him, Theo took a moment to catch his breath before turning back around to Stiles.

"Fuck," he breathed once again, at a loss for any other words, still coming down from the high of the most intense orgasm he'd ever had before the other kissed him again.

~~~~~~

I️t was later that night when they were lying in bed together that Theo's phone buzzed. He had been smiling, but as he read the text message, his expression entirely changed.

Stiles grew concerned as he immediately noticed the shift.

"What? What is it?" Stiles asked, worried.

Theo shook his head dismissively.

"It's nothing, don't worry about it," he assured, putting on a fake smile.

Stiles couldn't explain it, but the other just seemed off.

Theo gently kissed Stiles on the forehead before getting up from the bed, Stiles' eyes following him, a puzzled expression on his face.

"Wait, where are you going?" he asked as Theo began putting his pants on.

"Just getting some air. Don't worry about it," Theo replied.

Stiles shook his head slowly.

"Theo, who was the text from? What did it say?" he asked.

Theo sighed.

"Look, it was nothing, okay? You trust me, don't you?" he asked.

Stiles raised an eyebrow suspiciously. He was slightly irritated at the fact that Theo would really pull that care just to get him off his back. Stiles sighed after a moment of silence.

"Yeah, I️ trust you," he said.

Theo nodded.

"Good, so you have nothing to worry about. Goodnight."
