If you're intrigued by the three key themes of kidnapping, confinement, and training, this work is a must-see. Featuring four schoolgirl heroines—Shinobu Kasagi, Riko Hayase, Ai Kazumi, and Aki Aiba—an erotic training story unfolds. Men lure the girls with false promises like "do this and we'll set you free," then forcefully grab their heads to make them suck cock, or make them ride and thrust their hips during intercourse, aggressively teaching them lewd and erotic acts. As the story progresses, the girls' pain and oppression gradually transform into pleasure, creating a deeply immersive, highly addictive narrative.
