Whispering behind her back, playing with her nipples, squeezing her legs together, teasing and thrusting until she ejaculates – the devilish tutor older sister and Hinako Mori's abstinent life of thrusting. DVAJ-683

Hinako, a tutor, is responsible for teaching a male student who is trying to abstain from sex. However, she herself becomes aroused and unable to concentrate on teaching, causing the student's grades to drop. Realizing that the student's abstinence is affecting his studies, Hinako uses various methods to arouse him: touching him from behind, gently stroking his chest, whispering "You can only concentrate on studying after you ejaculate," licking his ear, and playing with his nipples. She then uses her legs to clamp him down and masturbates him, making her erect. To help the student, Hinako sometimes gently pats his back and sometimes sternly pats his buttocks to entice and tease him, using close physical contact and guidance to achieve an erection.
