If I had a tutor like this, I would study hard! ? Yukina is a female college student who started working part-time as a private tutor. It seems like the boy in charge doesn't have enough concentration and his grades aren't improving... If he cleans up his agonizing dick, he should be able to concentrate better! Yukina-sensei's idea (?) is to make Jubojupo pacifier! There's still some left, right? Even if he cums, he doesn't let go of the cock and gives it a follow-up blowjob.
