I was in a chair, my wife on the couch and her ex in a loveseat opposite her. I awoke to see him looking at her, she had one leg off the couch, and he... skirt was riding up. I didn’t move, but kept one eye open just a crack. He stood up and stretched, watching to see if I was asl**p. He walked over to me and nudged me with his knee, and I didn’t move. I started to make snoring sounds, and he bought my ruse. I knew he was going to try something, and sure enough he walked over to stand beside. Vivian reached behind her and unsnapped the bra and let it slide down her arms and off. Her breasts weren't large, 34B, but they were the first breasts I had ever seen and they looked beautiful. She had small freckles all over her chest but they seemed to be magnified on her breasts and then there were her nipples, nipples the size of pencil erasures and just as hard. I just sat there and starred at her.After a while she said, "Well, are you going to touch me or not? Hey mister, you don't think. She was less than gentle, pressing it firmly into my anal canal as far as it would go. Then I found out what she had in mind. “Massaging the prostate often hastens ejaculation, so I will do that in conjunction with masturbating you. If you can withhold your release a few times, you will have accomplished tremendous control.” That was easy for her to say, but her fingertip tickling my prostate, coupled with her slippery fist pounding my shaft was excruciating. It somehow excited me terribly. “I guess we’re a little old for this kind of thing,” she said.“You don’t look old at all,” I said. “You look great.”“I mean too old for the games, the preamble,” she explained and stood up. “Come on.”Rona led me into a palatial bedroom, neat and tidy with barely a sign of human habitation.Now that it was clear she was complicit, I took her in my arms and kissed her. Her big, low-slung breasts pressed temptingly against my stomach as my hands roamed her wonderful, mature body. I unzipped her.
