A schoolgirl who is not like a tuna, but like a cat, has sex without any interest. Her middle school teacher, her homeroom teacher... she takes advantage of the fact that she doesn't refuse and does whatever she wants! She pours her servile sperm into the womb of an underage girl! Plus, there are three special versions that will make you happy: the "I felt it" version where she is made to cum after her weak spot is discovered, and the "I'm fine with it but I'm pissed inside" version where she's Kokoro! Creampie is totally OK! "Eh? Creampie? I don't mind," says an excited old man as he engages in a real paid relationship with a modern schoolgirl. Part 2!
