Sakura has just moved in with her boyfriend. Next door lives Tomoya, a struggling student who is retaking his entrance exams. Tomoya is disappointed that Sakura has a boyfriend, but one day, when Sakura brings him yesterday's leftovers, her ass suddenly starts to ache and she presses her ass against Tomoya's crotch. "Please. My ass won't listen to me," she says, Tsukushi Tomoya with her ass.
