Jitaku Keibiin – Episode 1 (ES)

Tsunetaka has lived as the invisible ruler of his house for twenty years. When his father’s gorgeous new wife Shoko and her daughters move in, he immediately senses danger — they plan to seize the family assets and kick him out. With only five days until they move to a new residence, he must act fast.

His first target is the eldest daughter, Kashiki Sayaka — a stunning, well-endowed young woman with a gentle personality that makes her the perfect first victim. Using his extensive surveillance network, Tsunetaka gathers compromising material on Sayaka and begins his campaign of psychological warfare and sexual dominance.

Through secret recordings, threats, and relentless sexual training, he slowly breaks down her resistance, turning the once-proud big-breasted step-sister into his obedient slut. Every stolen kiss, forced orgasm, and deep creampie brings him closer to reclaiming total control of the household.

The mission has begun. The Home Security Guard is on duty — and he will use every perverted trick in his arsenal to defend his domain. Expect heavy focus on voyeurism, blackmail, huge breasts, and gradual mind-break corruption in this opening episode. (
