What a fucked up thing that was, but I got to do mom's man, without her knowing.I called mom to throw her off, while she waited for him to get back to...her. I told her daddy was happy that she agreed to come over for dinner. She told me she didn't know where Jackson was. I asked who that was, when she said that's who I walked in on today. I giggled and said that he was a big man. She said that the first time they fucked, they fucked for two days and she could barely get up to walk.I got. I then remembered this tight short gray skirt she had and decided to try it on and the thrill was building. I walked in to my parent room and went through my step moms stuff still in my sisters panties and skirt and found a pair of decently silky pantyhose so I put them on as well my more yumminess I went back to my sisters room and looked around for a bra well i found a few but none fit right, my step mother on the other hand a a lacy black front clasp bra that ones I saw it i fell in love. I guess we had gotten too quiet, because her dad came in to check and see what we were doing. No k**ding, we all started blushing, because of what we were talking about, he thought he caught us doing something we weren't supposed to be doing but left the room again.We talked for about an hour about "thingies" or "pee pees" and loved the stories she was telling us about her dad. Finally, she asked if we wanted to see it. We all looked at each other grinning and agreed, kind of sheepishly,. “That is perfectly fine with me. You two do what you need to do and when you two are ready for me I will get everything ready on my end, okay?” We agreed to that. Those two hugged. I shook her hand but she hugged me too. Greta didn’t make a big deal of me and Francesca hugging. Francesca smelled incredible. She smiled at me, I smiled back, and Greta teased me by lightly hitting me on my butt. We said goodbye and she left. I noticed she’d made coffee. What an angel I thought. “She is married,”.
