anyone here knows a MANGA where the uke kinda turns to demon and his friend helped him however the uke wanted to also help the exhausted seme so the uke collected semen with another hot seme in the car xD... and this younger brother of the another seme likes the main seme so he ended up setting the uke to a bad situation hehehehe
