Bobby was seeing stars from the rapid thrust of Peter's hips. He never did anything slow, nothing was gentle. So this was the perfect speed for Bobby Drake; fast and hard enough for him to get lost in it, for his mind to drown beneath the ecstasy of pure sensation and keep him from overthinking, from being nervous or anxious and overcompensating because of it. And maybe right then it was all the more important because Bobby wasn't thinking about being ripped out of his time (again) or ripped out of his dimension (again) and away from everything that was good and familiar to him. All of that faded away behind the feeling of another man pounding inside him.
And Peter was taking him there, exactly where he wanted Bobby to go. He could feel the growing hollowness that his lover had fucked inside of him. He could feel the perfect impact of his hips and the way his balls slapped against his ass. He could feel the contours of Peter's cock stroke against something inside him that was purely fucking electric. It all directly fed into a pressure that was building inside him, one that was crawling its way through his body from his pelvis and into his manhood.
All track of time was gone. Bobby couldn't say how long he lasted, whether it was thirty minutes or just ten. His skin was covered in glistening sweat, warm to the touch in one of the rare instances since his mutations emerged. By the end, he was writhing beneath Peter, unable to contain the pleasure that this man was beautifully inflicting upon his body. His fingers pressed into Peter's shoulderblades and raked downwards, leaving red lines. His toes curled tightly and as that bubble of pressure popped inside of him, Bobby could feel his hole try in vain to constrict again around Peter's girth as his kegel muscles contracted. Bobby erupted between them, ropes of sticky opaque fluid splashing across their torsos and chests. A spurt of it even reached up to Bobby's face, splattering across his cheek.
And so Bobby came apart, raking his fingers down Peter's back and crying out his lover's name.
