"No way, Jose! Forget it." Okay, see ya later", I said and went back to my book.Marilyn looked surprised. "I thought you said you were gonna do it?"I ...ut the book down for the second time. "Oh, I am. But you're not going to be there." Fine," she said and stormed out of the room. Shit. Maybe I pushed it too far. I waited for a few minutes and was just about to call her back when she walked into my room."I've never done anything like this before," she said, as if I had thought otherwise. I tried. She grabbed the ring at the base, pulled and let it snap back on the base of my shaft. I winced in pain.She moved forward so she was on her knees and straddling my cock. She reached down to hold it straight up and slid her pussy on it taking a couple of inches. Up and down she went on the head a few times then she came down all the way, my dick all of the way in her. She gazed at me for a moment, then her husband put his hands on her shoulders and pushed her forward so she was laying on. I reached under the bikini again and grabbed two handfuls of her ass and kneaded, gently at first but gradually more firmly. Sharon was rolling her hips now and I kept up my massage. Her ass reminded me of Heather’s — in the later years of our marriage she had put on some weight and her ass had become plump and full, with round cheeks that you just wanted to sink your teeth into. I was having a hard time resisting that very impulse with Sharon squirming underneath me, her breath coming in. .." I stuttered. "Am I too old to complement on your ass?". "Uh...well...No you're not. Thanks for complementing on my ass." I ended the conversion exchange there as I was getting very nervous. As I was walking to my house, I looked back at her one more time, and she had a very sexy smile on her face as she was looking back at me...like... You see this emoticon? :J That smile...yeah.Then I thought to myself, what do I do now??? His mom is one of the most beautiful, curvey, older women I've ever.
