She hadn’t been prepared for this and only wanted to talk to him. So she was caught cold and not even aroused.Nonetheless she had a loving feeling i...nside. His b*o had mounted her so many times today and her boyfriend had nothing. So this was only fair. And from what she had learned in the last days, it was a natural woman's plight to open her legs and ease the male needs.A moment later her boyfriend stood up, fixed his trousers and turned to go back to work. His dad would come over any moment. . If you are disturbed about older plumper mom and mature son sex this story is not for you. Mom called me again wondering if I could help her when she went for another bath, I was at her house as soon as I could after knowing what happened last time. Crippled with arthritis and waiting for a new hip my larger plump mom needed a helping hand with things and reassurance in case she fell.I wasted no time in undressing her as the awkwardness between naked mother and son had been conquered last. But we'll have to do somethingabout your friend down there." We both looked down to the unladylike bulgethat was straining at my new panties. "Mom, I..." but she put a finger to myred lips, her voice low and secretive. "Honey, that just means that you'reenjoying yourself, don't worry about it, just tuck it back and under so itdoesn't show." Turning my back again, I wrestled the straining member towhere only a little showed in front. "We may have to get you something forthat." she said, hinting. I told her stay still I will get the shoes before you fall into something and get hurt. I didnt realize when I offered to do that I would be just inches away from her panty covered vagina. I was close enough I could smell her sweetness as well as the sweat from a night of partying. Her panties were tight and I peeked towards her and got a full visual of the perfect shape of her labia. I was so turned on by my own sister I felt horrible. She acted as if none of that happened or at least she.
