High school teacher Yukino has a sexless marriage with her husband, and leads an unfulfilling life due to her own sexual preferences. Overcome with desire, she uses a meetup app to have a one night stand affair, but the one she had an affair with turns out to actually be a student from her school: a forbidden, immoral, teacher–student love triangle sex story.

A series of unrelated slightly erotic short stories… or is it?

Miyu, my own sister, catches me masturbating to my favorite "sister" erotic game! She's always cool, straightforward, and a bit salty, but for some reason, she ends up helping me masturbate...! I began to cum on my little sister's skin and have her touch it! After a lot of skinship, now I can't bust a nut unless I'm thinking of her! Genichiro Kazami's popular Web novel about little sisters is now available as a comic book by Hayate Asakura, a moe illustrator!
