Big-titted office lady lured into an orgasmic hell—experience the ultimate in full-body restraint, voluptuous pleasure, climax, and trance. Chitose Yuki is walking home from work when she's suddenly attacked and kidnapped. Realizing her situation too late, her curvy body is shoved into a wooden crate rigged with aphrodisiacs, sex toys, and a waiting man's body. Trapped and immobile, Chitose is forced to submit to cumdump training. As total restraint overwhelms her senses, she succumbs completely to its pleasure. "You're just a sex slave—no need to move," she's told, and from that moment, her body no longer seeks freedom.
