I took off my own shoes and crept up the stairs to our bedroom, the door was nearly shut but I could just see my wife's naked body through the gap by ...he hinges. I could see that She was sitting on top of a naked man with her hands around his cock, I stood there thinking I should be angry, but I was turned on and could feel my cock getting very hard.I wanted to get a better view so I slowly pushed the door open just enough to see their reflection in our full length mirror, what a sight it was,. "If she comes to my room, yes," I replied, watching Tracey carefully."And if she doesn't?" I sleep alone," I chuckled."I could always pop in," she said."I'd like that." So would I." Do you think Mum will guess?" Tracey asked."Guess what?" That you're fucking me." Probably, I think she suspected what we'd get up to if we were left alone together this morning, particularly as I told her that you knew," I replied carefully."You told her?" Tracey's eyes were wide with surprise."Yes, she had a right. The cum from my own premature orgasm had made my ass slick and was lubricating his cock as he slid it up and down the crack. Taking both my wrists into one strong hand, he reached down with the other. I felt him position his cock against the tight opening of my ass and he pushed. I couldn't escape the pressure of his penis against my asshole. He was too strong, and I felt him enter me. Remembering how I had done it with my dildo, I relaxed as much as I could so that the cock in my ass was only. "Well only a girl would say that Jessie! There's no man I know that could put up with all this girlie pleasure! We'll have to pick out a few outfits for you to wear while you're here... would you like that? I know I would!" "Yes... please, this dress is superb to wear... and the underwear is... well." I replied but she interrupted saying."You don't have to say it dearie, all girls know the pleasures of silk lingerie... it brings a smile to your face and a few other parts as well!" She laughed,.
