Your side piece turns up at your house late one night suddenly and you try to usher her away. Your wife is home and it's your date night! Thing is, your mistress isn't going anywhere. She knew your wife was home and she didn't care. She's desperately horny and wants you to fuck her right now on your wife's couch. You're busy trying to reason with her when your wife comes down from upstairs... your side chick sees her and immediately starts winding you BOTH up. She reveals everything to your wife - causing her to break down in tears on the stairs. Your side chick doesn't care and laughs at and insults your wife - the sounds of her whimpering seem to make her even hornier. And... like it or not, your cock is hard from watching her writhe around in her tight dress and flash her pussy through her sheet black thong. The sexy younger woman bends over on the couch and rides up her dress to reveal her perfect thighs and arse - she shows her body off to not only you but your wife too. Reminding her that she's passed it and that she could never compete. You can't help but grip her hips and slide your huge erection into her pussy from behind. You ride her tight little body on the sofa - appreciate her warmth and tightness. While you fuck her, she looks directly at your wife. She tells her to watch as her husband disappears into her holes and to pay attention to how much he's enjoying it. She reminds your wife that she's never felt this good before and she certainly never will again now that she's so old, fat, and boring. Your wife whimpers in the background the whole time. Insult after insult pours from your hot mistress' mouth - in between moans - until you feel her tiny body shudder to orgasm around your length. Feeling her pleasure encourages you to do the same and spill your seed into her belly. She looks at your wife, with your cum dripping from her holes, and tells her that she sincerely hopes you just got her fertile, capable body pregnant. She tells her she's pathetic for not even trying to intervene in the adultery that she's just witnessed.
