SNOS-410 I lusted after my cowardly niece who couldn't say 'stop' and kept fucking her in secret... she unexpectedly became a slave to Uncle's dick. Moe Sakaki.

I've developed feelings for my brother's daughter, what a piece of shit I am... My niece, whom I haven't seen in seven years, is right in the middle of puberty. Even though we started living together, she's cold and seems to be avoiding me. However, her unguarded appearance in her sleepwear at home drives my male rationality crazy every day. One day, after his brother and sister-in-law went out, leaving them alone, he finally couldn't hold back the urge and attacked her. After realizing the gravity of what had happened, he was terrified that she might tell his brother, but several days passed with no change in his brother's behavior. For some reason, she remained silent. What the hell are you thinking…? Even if I do something perverted again, there's no resistance. Since then, I've been hiding from my brother and his wife, having sex with my niece who is 17 years younger than me.
