I'm trying to find a Yaoi I read recently, it's about two guys who are majoring in science in uni or something and the seme wants to get close to the uke but the uke's really cold to him. There's this guy who uses the uke for a science project and keeps him traped but the seme saves him but after that the uke has sudden spells where he becomes exited.
Any ideas guys ??
Sounds lie Kokuin.

Looking for this yaoi where the uke is operated on or something against his will and after that he becomes aroused uncontrollably and out of nowhere (p much like full on omega heats)
