He'd loved fucking his son's wife from the first time they'd shared an illicit fuck together but knowing that he'd fathered her child that was growing...daily in her womb made him insatiably horny for her hot gravid pussy.One evening Sue had invited Cindy and Tim over for a typical evening of "family fun" and after dinner the four adults gathered in the guest bedroom for a lusty time of sex together. Sue and Chuck had moved a second queen size bed into the guest room so that the two couples could. Thankfully, he got the message.On the way, she placed her left hand on my thigh, and started to stroke it like she had been stroking the tree limb. This gave me an immediate hard on, and she looked down, then smiled and me and moved her hand to my cock and continued stroking.There was little talking, but she asked my brother if he was interesting in hanging out with us for a while. At first he seemed not to know how to answer, so I told her that I was sure he would be up for whatever she. Mom made no protest nor any attempt to stop me and eventually I was at dress hem hight. Without giving myself time to consider what I was doing I carefully grasped the bottom of her dress and moved it higher exposing the bottom half of her bum clad in the white panties. I rubbed the sun-lotion on all the bared skin right to the edge of her panties, noting as I did so that Mom's thighs seemed to part even wider, as if with a mind of their own, allowing me to apply lotion between them. I did. He caressed both thighs through the panty hose some more, then stroked upwards toward their junction. His mouth returned to her breasts as he stroked her through her panties. Still, he wanted even more intimacy.“These are lovely,” he said of her lacy panties, “but aren’t they in the way just now?” She raised her middle for him to take her panties off, and again for him to roll down her pantyhose. Every revelation of her skin looked delightful, but the contrast with his clothes made him feel.
