After discovering a student aimlessly standing by the roadside, unable to return home due to his parents' troubled relationship, female teacher Yuu Shinoda takes him in, unable to leave him behind. To help him vent his pent-up emotions and clear her own mind, they drink together, lowering their inhibitions—until the student's pent-up sexual desire suddenly erupts. Despite it being his first time, he passionately engages in deep tongue-kissing, awakening Shinoda's own primal instincts as a woman. Their tongues hungrily intertwine, mucous membranes sliding against each other as they greedily devour one another, climaxing with repeated creampie after creampie. Filled with youthful intensity, their fierce thrusting leaves the female teacher drenched in sweat as she reaches multiple orgasms. An utterly erotic night unfolds, with the submissive teacher continuously brought to climax through thick, sticky sex that lasts until morning.
