In a dream school where 'nipple tweaking' has become the norm, Teacher Yume goes on a rampage! Licking the clitoris and handjob are basic, while mutual licking of the clitoris in Tic-Tac-Nine also stimulates nipple tweaking in the cowgirl position, pushing the nipples to the limit and teaching the deadly machine technique of ejaculation, even cosplaying as Teacher Yume's pink nipples, using every possible method to tweak the students' nipples! Sensitive nipples lead to internal ejaculation and explosive orgasms, with female students climaxing one after another! "It's okay, nipples don't come off that easily, so let's tweak them even more and raise the excitement, okay?"
