To earn money for living expenses with her boyfriend, Konoha Kasukabe secretly begins compensated dating. She falls into the network of an older man who habitually films amateur gonzo sex. A wealthy predator with malicious intent, he targets her as the perfect candidate to train as his personal sex slave and cumdump. To protect her life with her boyfriend, Konoha ends up allowing not only gonzo filming but also bareback penetration. Forced to satisfy the man's twisted desires, she is gradually corrupted through relentless, lewd sexual training—an intense descent into submission that delivers must-see results.
