At 35, Kay is very different from her Ann. Blonde and blue eyed, and about 5'6", Kay is built like the proverbial brick shithouse. She often jokes, th...t she got the tits that Ann missed, a very hefty 36 DD. But, other than her tits, she is slender hipped and has nice, slender, well muscled legs. To keep trim, Kay is fanatic about working out on a Stairmaster. When she arrived, I was surprised to see that she had lost a few more pounds, which emphasized her large breasts even more.Anyway, Kay. 45 in my belt and headed back up the stairs.I walked to the bedroom doorway and then just stood there and waited to be noticed. Marge was on her knees; head resting on her arms and the guy was behind her pumping away. Marge was moaning:"Fuck me, fuck me baby, that's so good, fuck my ass baby, fuck my ass."Now I was getting really pissed. I had tried for years to get Marge to try anal sex and she had always said no, that it was too disgusting and she could never do such a thing, and there she. She preferred sitting down on the floor. So I sat on the chair working on my laptop and she sat down pasting pics. I had a very good view of her cleavage from here. I could almost see her nipples.And sometimes when she bent a little more I could see her butt crack emerging from under her jeans. I was staring at her awesome cleavage when suddenly she looked up asking me for the scale. She caught me staring at her cleavage but she made no attempt to hide it. I was starting to feel a bit horny. We did that for about an hour and we proceeded to play other games, after a while we decided to just have fun and play poker. We divided the chips between us and played for another hour or so. When you’re not playing for money poker can be kind of boring and I could tell the girls had just about enough, I looked over at Mike and gave him a nod that he had been waiting for. You see Mike and I have oftened talked about fucking each others wives but never came up with a way to do it, until last.
