DVAJ-683 Whispering in my ear from behind, teasing my nipples, and jerking off with her beautiful legs while holding me down, making me cum and explode, the little devil tutor sister Yuka Morihiga zeroes out all my distractions as we live a life of studyi

Tutor Hinao is in charge of a male student who is abstaining until he passes his exams, but he can't concentrate on studying due to his urges and his grades are dropping. Judging that the student's abstinence is hindering his studies, Hinao says, "Your grades are bad because you have distractions..." as she presses her breasts against his back from behind while he's studying. She whispers in his ear & licks it & tweaks his nipples, making his abstaining dick rock hard. Hinao holds it with her beautiful legs and gives him a footjob. For the sake of the student, Hinao sometimes gently pushes his back to encourage him, and other times strictly spanks his ass for teasing from behind. She excites the student through close one-on-one guidance.
