Hentai University follows you, a hypnotist recently employed as a student-councilor for the local university, going around the town and getting sexually involved with people from both the university itself and the surrounding town. The characters are taken from CG sets by artists like Oreteki18kin, Nagi Ichi, and Enomshima Iki. This game can be played in-browser and does include a mobile version.
