Co-ed Sexxtasy

Nagi is a young woman whose biggest problem seems to be her horny boyfriend, Akira. Their relationship is a constant cycle of sexual tension and frustration, with Nagi often feeling neglected and longing for his attention. When a fever and a rectal thermometer spark a new kind of desire in her, their dynamic takes an unexpected turn.

As Nagi and Akira navigate their passionate relationship, their friends Yukika and her boyfriend join them for a trip to the hot springs. A jug of wine leads to a wild four-way orgy, and Yukika later assists Akira with research on positions from a tantric sex manual. Meanwhile, Nagi, tired of being ignored, boldly removes her panties and begs Akira to satisfy her. The story follows their erotic adventures, including a visit to a public bath and encounters with phallic toys and a traditional festival.
