Susan then left to go do some errands and I went to work. I got done with everything about 1:30, and Susan just got back then. I was taking my tools out to my car, when i saw her. I told her that her bathroom is complete and can be used. She was so excited and went in to look. She said it looks so much better than it did before, now that it is cleaned up, and definitely better than it used to be. I said she can use the shower now and everything. She went into her bedroom a minute and came back with two towels and was naked, and said lets try it out. I said, don’t you want to try it out with Bill? She said no, he’ll get plenty of chances with me in there. She said get the clothes off and join me. She started the water and got it nice and warm and then led me into the glass surround playground. We kissed again and then she got on her knees and started sucking my cock, and got me hard in no time. She laughed and said wow, you young guys do get hard quick. I reached down and played with her nipples for a few minutes as she sucked me off and then pulled her up to me. We kissed again, then I spun her around, and she bent over, inviting me to fuck her again. As we started fucking, she told me to really fuck her hard this time. I need to feel that big cock deep inside me. So I did, I fucked her so hard, and with the water flowing over us, it intensified our body’s slapping sound. It did not take long for either of us to cum again. As we came, both of our legs got a little shaky.
After we dressed again, I got ready to leave and she held my arm and said I was the best son in-law a woman could hope for. I told her she was the sexist mother in-law a man could ask for too. She laughed and said it would be great if the four of us could swing one time together. I said I would be game, but sure about the other two. She said oh well, at least we had this today, and I am happy. She then said maybe just the four of us in the hot tub with you and Carol fucking while me and Bill fuck. I said if you got Carol drunk enough, I could see that happening. She laughed and said, well let’s work on that.
We never did repeat this act, although there was a few times we both wanted too. Carol and I did go over there one weekend when Bill and Susan had guest there, and we all ended up in the hot tub naked. Carol was a tad bit drunk and started playing with me, and I said dear, you better not start something, we cant finish. She said look at them, like they would care, as I looked over and saw Bill playing around with the other couples wife and Susan and the guy were in a heavy lip lock. We did end up fucking out there for to see. Carol even came real hard too. I think she was totally into just to sex that night. Susan saw me the next morning and said that was awesome and she got off watching us two go at it.
Carol was a little more subdued that morning and told me she couldn’t believe we fucked in front of her mom like that. I said now dear, you were the one that wanted too. She chuckled a little and said yeah, I guess I did. I said at least we didn’t swap partners. She laughed and said ewwwwwwwwww, no way.
I am pretty sure Susan took what we did to her grave, for I know I never said anything. I did feel some guilt at first, but it passed, and I did loosened up around Susan after that, which made Carol happy.
