Immediately I knew that I was right--Mom was not wearing panties!Mom had her legs closed tightly, but I began running my hand all over her upper thigh... and lower belly, loving the feel of that rather crispy hair covering her mound. I tried probing lightly at the vee which Mom was keeping protected. At first it was almost imperceptible, but then I knew that her leg muscles were losing some of their firm tension. I probed a bit more insistently, and bit by bit, my hand was able to creep between. I replied:My heart has been yours from the moment we first met. Although so much time has passed my love for you has not changed, except to grow deeper. My dearest wish is to be in your arms, loving you, or on the floor, serving you when the desire takes you. Tell me what you want.I waited while he replied. I wanted to cum there and then, just reading what he had already said, but I knew the best was yet to come. Finally the reply came through:These are the things I need and expect:You will. We had a very secluded beach and the second day there the girls went topless. A few people on the beach had gone totally nude and one afternoon after many drinks we all decided to see what it was like. It was the first time I had seen her nude in front of people and I can't tell you what a turn on it was.I told her about it that night an she thought it was a little weird that I would get a turn on from of other men and john seeing her but she laughed and told me she would go nude on the beach. Suddenly a thick squirt of freezing lube landed on my anus. "I asked if you're ready for this you dirty slut?"Now I knew she was repeating last night in reverse."Yes. Oh, fuck yes!" I moaned. "Please fuck my ass, my dirty fat ass!"That was all it took. Almost before I finished talking I felt the tip of the dildo pressing into my tight asshole. Easily, I took it. Bearing down I slid backwards, taking every inch inside me.The look of surprise on Anna's face was priceless. I'm sure she expected.
