The day before the cultural festival, Kozue is scolded by her classmates for skipping preparation, being told, "You're ruining the class unity!" As punishment to show remorse to the teacher, she's ordered to stay completely naked all day. Trembling, she wonders, "Was it really that bad that I was the only one going to cram school?" Dazed by the teacher's harsh reprimand and stared down by her peers, she finds herself in home economics class—baking cakes. She tries to cover her shapely breasts and crotch with her arms while working. The teacher barks, "Beat it properly!" and snaps, "Don't hide your body!" She's made to pick up tools deliberately dropped on the floor, trampled underfoot, and forced into the humiliating act of wetting herself. Accused of not repenting, she's ordered to mop the floor. Whipped cream is smeared on her nipples, decorated with strawberries. Her body becomes a sponge cake, piled high with cream, and male students lick it off—making her whisper, "What should I do... I'm getting turned on..." When she shows defiance, she's dragged into the toilet and yelled at, "Is cram school more important than the festival?!" While receiving rough fingerings that make her gush, she's forced into a relay blowjob on a cock whip. Pressed against the sink, she's pounded from behind as someone shouts, "Look at your face in the mirror!" She screams in pleasure, "What's going inside me now?!" as cum is shot into her ass. Spanked and forced to clean up with her mouth, she's taken standing at the urinal in missionary position. A threesome follows, and finally locked in a private room, endless brutal pissing continues. Her moans echo, mixed with cries hoping someone will come.
