In the quiet drizzle, schoolgirl Mirei stands at the entrance wearing a modern-style uniform, saying, "I'm here for the home repairs." Lured by her voice, she tries to enter the house, setting off a calculated strategy to satisfy the men's sexual desires. She's guided to the changing room to avoid her mother's notice, where slaps, tongue kisses, breast groping and licking, handjob and cunnilingus gradually break down her resistance before leading her into the bathroom. Under water torture and intense deep throating, the overly sheltered, affection-seeking girl is submerged in the bathtub, completely overpowered and surrounded by cocks, ready to be ruthlessly fucked. Waiting for her in the Japanese-style room, the men taunt her with spitting, then roughly finger and lick her, stimulating her erogenous zones until she gushes multiple times in violent squirting orgasms, still fully dressed in her uniform. Threatening her with, "If you don't want your older sisters raped, stay quiet and let us creampie you," the youngest sister, devoted to her siblings, pleads, "Please... don't touch my sisters... just creampie me." Unsatisfied with mere creampie, they devise a plan to record the act and show it to her older sisters. A thick cock plunges deep into her molten, soft pussy, and while filming, they pound her relentlessly in various positions—missionary, cowgirl, doggy style, rear entry. No matter how much she cries or screams, the stiff, lewd cock prods deep inside, making her experience her first internal orgasm. One after another, they creampie the melting-faced schoolgirl in consecutive orgasms, savoring the ultimate pleasure to the fullest.
