I remember reading a oneshot where a guy meets a kind of delinquent boy with dark hair who is very strong. I think there was like a second part or a short about how they're doing after they start dating. Because the uke is strong, he clings to the seme during sex and injures him? Something like that. In the second part, they try tying the uke up but I think he breaks the restraints and injures the seme once again. Pretty funny. Pretty cute. I was convinced it was by Chitose Piyoko but I've combed through all of those (And related searches) and it doesn't seem to be right even though the ukes look right. Maybe I'm overlooking something or misremembering.
