Not everything could or should ever be perfect. Severus felt this intensity for Sirius, this odd connecting kinship, he just didn't enjoy it as much as the other boy so obviously did. Their hands touching, their lips brushing, their sweat mixing...

It was raw and wonderful, though Severus stayed limp in Sirius's hand. It would take a time or two more of thistl desensitize him enough for genuine pleasure. If there would ever be another time.

That didn't mean that Severus only felt pain. No, that was replaced by being full, and that alone was joyful enough for the purring to start again. Severus, of all things, was incredibly loud while being shagged. And almost quite the demanding little kitten as well.

"Bite me... Hurt me... Do it harder--" The rest was hardly English.
