Derek is his anchor, even if Peter doesn't really think of it like that. It's not just about needing to be fucked, needing to feel, wanting something, someone to fill that empty, hollow feeling. It's that thing they both ignore, circle around -- they both know who belongs in the empty spaces inside of him. But being Mated, admitting to it... it's the most iron-clad cage Peter ever would have accepted willingly, and the thing is, that he does accept it willingly. It's not because Derek is his Alpha, it's because of this feeling, because somehow they got tangled up in each other, and Peter needs him, needs Derek.

And then Derek says yes and it draws a soft whimper from his lips and his breath catches as he shifts against him. He moves easily over Peter's smaller body. He's slender, lean muscle, but he's short; shorter than Erica when she's wearing her heels. He whines and arches as Derek nips at his lips, the older werewolf wrapping around his body, ontop of him, and Peter needs him, needs this. He kisses him, sudden and a little uncertain, needy. His lips a little rough, but it quickly turns to teeth, turns to biting and nipping and pulling Derek in.

He needs him, wants him, and admitting that is like a powder keg, like knocking over a tower. The need that grips him is fierce, unrelenting, intoxicating. He needs Derek, needs his Alpha, needs to be locked together, to feel how their bodies curl when they're joined so intimately. His legs spread and his hips jerk up against his Alpha's body, a rough whimper that he breathes into Derek's mouth.

"I want you to knot me. I want- I want it to be you."
