Hikari is a high school girl who throws herself wholeheartedly into her club activities. Devoted to her basketball team, her life takes a dark turn when she meets a seemingly kind older man at a house where she's staying—one who is secretly a throat torture specialist. To continue participating in her club, she's forced into a contract of submission with him. In exchange, she endures extreme training: esophageal torture, vomit-filled deep throating, candle wax, whip flogging, choking, slapping, and head pounding. Further pushed to her limits, she experiences pregnancy breeding, deep-throat ejaculation, swallowing cum, and bareback creampie sex. Bound by servitude to support her club life, what thoughts go through her mind as she makes this choice? As her teammates cheer her on, what will become of her? [Day 1] 1. Bowing deeply and walking with upskirt exposure 2. Vomiting while her uniform is groped 3. Sex with deep throat and throat ejaculation 4. Wax and whipping while restrained 5. Upside-down deep throat with brutal throat pounding and cum drinking 6. Drenched in massive facial cumshot and piss [Day 2] 7. Sex during basketball practice 8. Electrostimulation torture while wearing basketball gear 9. Tied-up deep-throat creampie fuck ※All performers in this work are adults aged 19 and over.
