I had stuck a finger up my ass and it landed on my "G" spot (prostate). At about the same time I discovered the nerve endings in my sphincter (boipuss...). In these ten years I have had quite an activity in my back door and today I enjoy both DP, from two women with dildoes and two men. I Have found that the warm sperm deposited in my insides provides me with quite an explosive orgasm. The special solo masturbation day was produced by the first time that I used our big, big dildo all by myself.. This time it was a round chamber that had half a dozen pipes feeding into it. The chamber was only big enough for one person to fit through at a time. As for the six pipes they were only about a foot in diameter, but that was okay as we weren't going any further underground. There was a culvert lid above us and we were going out of it, or we would once I'd shifted it.It took some doing but I did it. Once it was lifted and pushed out of the way, I scrambled out. The culvert opened in a cellar. She started to massage his balls, and he knew there was no point trying to protest any more. He might as well just enjoy what was going to be the most fun he had had in a long time.“OK Chelsea, you win” he said. He pulled his cock out of her mouth, a gentle pop as her lips released it. Saliva was dripping from her mouth. He wiped her mouth with his hand, and she grinned. Her eyes dancing as she looked at him. He lifted her t-shirt over her head. Her blue lacy bra was barely keeping her boobs in. Mom was 55 years old. Over the years she'd put on at least 20 pounds, most of that on her ass. My grandmother was at least 75 and skinny as a nail. Both women had rather large racks on them. But time and gravity had caused them to hang low on both women. Earlier when watching the video I had noticed my mother had large pussy lips and there was no doubt that the large nub I saw at the top of my grandmother's hairy pussy was her clit, at least I think it is called that. I lost track of time but.
