IPZZ-697 Yume Nishimiya, a cheeky schoolgirl, has her sensitive nipples repeatedly played with by her hated middle-aged teacher, who is so fondled by them that she experiences nipple orgasms so intense she loses control.

It's seriously gross, so don't touch me! Before summer vacation, Yume is called by her homeroom teacher, Saito, a notorious masochist. He tells her that her attendance and grades will put her at risk of not graduating if things continue as they are. Confused, Saito suggests intensive extra classes over the summer... Threatened by a disgusting middle-aged teacher with a mother complex who makes her vomit... the worst summer extra classes... and forced to attend school without a bra, a humiliating experience. Slowly... gradually... he plays with and kneads the erect nipples of a cheeky gal in a uniform. She's developed into a premature ejaculator who orgasms from her nipples even with the slightest stimulation... Her sensitive nipples are teased, pinched, and licked, causing her to urinate multiple times! Her nipples are constantly teased during blowjobs, penetration, and orgasms! Oh no, I'm going to cum from my nipples!
