HUNTA-607 Thanks to my sister-in-law, I am able to do naughty things every day. My stepbrother, a hikikomori whose parents remarried and decided to live together, is a sexual monster! 2 Masturbate endlessly every day. My sister-in-law is horrified when she sees this. I can't sleep because I'm worried about when someone will touch me... And to my horror, my sister-in-law was wearing underwear...

A sister-in-law is terrified of her withdrawn brother-in-law who has an abnormal sexual desire and masturbates endlessly every day. He feels a sense of crisis as he does not know when he will be attacked, so he puts a woman who comes to his house to sleep with a sleeping pill and sacrifices his brother-in-law in her place! He plays with the sleeping woman's body as he pleases, and even if he ejaculates, he immediately erects and inserts himself continuously, so even if the woman wakes up, he doesn't like it, but he cums so much that he feels like he's fainting.
