This guy was so mad when his wife went on a business trip for a few days, making him extremely horny. At home, he often bumped into his sister, because he saw her dressing so horny at home, so he followed her. This guy peeped on her while she was bathing, even masturbating in her room. Unable to bear it any longer, this guy raped her late at night while she was fast asleep. When she woke up, she understood what was happening, although she resisted strongly but failed. And in the following days, the two fucked each other tirelessly.
