A low whimper escapes him when Peter pulls out completely, his body aching from the loss of him. "Peter, please!" Stiles whines, moaning moments later when the werewolf slides back into him, his body warm and accepting. God, he loves the feel of Peter inside of him, claiming him for his own.

His breath catches a little at the feel of his hand on his throat, but he just tilts his head back to expose more of his neck for the wolf.

Moving his other hand from the wall, which causes him to be pressed against it pinned between Peter and the shower wall, Stiles reaches back to grip at Peter's hip, blunt human nails digging into the skin.
