I was getting my son ready for school and notice him staring at my belly. I come over to him asking if he can help rub oil into my belly. It made me moan a little and I tell him I notice a bulge growing in his pants and he must have a pregnant fetish. I mentioned that dad and I haven’t had much sex lately since I’m so big and I’m really missing it… I take his pants off and start to ride him. He gave me a huge cream pie, I showed him as it was dripping out of my pussy and I thanked him for it.
