When I go back to my parents' house, I meet my ex-girlfriend who married my younger brother for the first time in a long time. Her plump and lewd lower body seems to be tempting me, her brother-in-law and ex-boyfriend, as she flashes her panties. I can't resist the sight of her panties and breasts while cleaning early in the morning, so I hug her and she doesn't seem to mind. She seems to enjoy the thrill of kissing and giving me a blowjob next to my mother and husband. I rape her in the entrance as I see my mother and brother off. She goes to the kitchen with my penis inside her, and we go crazy and get fired up for adultery sex.
