Hinako tutors an adult student who has sworn off masturbation until he passes his exams, but constant arousal is ruining his concentration and grades. Deciding his pent-up lust is the real distraction, she presses her breasts against his back while he studies and whispers that one release will help him focus. Ear licking and nipple play make his neglected cock rock-hard before she traps it between her beautiful legs for a teasing leg job. Sometimes she gently encourages him with sex; other times she spanks him and torments him from behind, using intimate one-on-one lessons to get both his cock and his motivation back up.
