VENX-124 Mistaking my sleeping sister-in-law's butt for my wife's butt, I inserted it immediately without knowing it was my sister-in-law. - Alice Kisaki

Shinji tries to make up with his wife, who is asleep after fighting over trivial things, by having sex with her. - While massaging her plump meaty buttocks, she cums all over. - When I felt more comfortable with the tightness than usual and pressed for a kiss...it turned out to be my wife's sister who was there! - "I-I'm sorry, sister-in-law!" Shinji prostrated himself and apologized, but the sister-in-law forgave him, but she couldn't stop her body from starting to ache.
