Chances are at this very moment my fat wife Adelle is fucking her boss. She thinks I don't know about it. However leaving her phone in her jacket pocket and it phoning me, (I was the last person she rang earlier), gave me the perfect opportunity to listen to them fucking in his office five weeks ago. I could her telling him to fuck her asshole, and I knew why. He probably wouldn't be able to get near her pussy, she's become that fat. If I was anyone else or I cared, I would probably have driven over to their workplace and beat the shit out of him.
The fact is, only an hour earlier my wife's younger sister by twelve years, had taken two loads of my cum over her face and up her asshole. Kelly is everything my wife isn't. Slim, attractive and always horny for sex. Also unlike my wife she adores dirty hard sex which turns me on incredibly. Kelly moved in with us after the break up of her relationship with her ex fiance. Five days after she moved in she entered our bedroom after my wife left for work and the rest is history.
It was fun lying on our marital bed with Adelle's younger sister, listening to her ask a guy to fuck her asshole. It was more fun spending the next half an hour having oral sex with Kelly. Driving her wild from one orgasm to another with my tongue and mouth. Kelly asked me a few days ago if we should move out together. I think I'll seriously consider it, if I can catch Adelle with her boss. Just have to think of a way to do that.
