I placed the other towel on the armchair and hung my legs over the arms.“Come, close girls, watch and learn,” smiled Sarah. Both girls eyes were w...de, but they did as instructed. Sarah carefully showed and named all the parts of her vulva and vagina finally spreading herself as wide as possible so that they could see her cervix. The two girls were transfixed. I could see that by the time she was finished that Sarah was intensely aroused, as was I.“Now I’ll masturbate to a climax,” Sarah. I was mostly just loosening myself up while I waited for the streetwalkers to come out later in the evening.Brittany came by first, with creamy white skin, teased platinum blonde hair, and a perfect heart-shaped ass. She always walks the club in hot pants and a tiny string top on her A-cup titties. On stage, she wears the tiniest thong imaginable that basically shows her entire gorgeous asshole. Snapping her gum as she said hello, she leaned in and kissed my cheek. I could smell her usual. In the kitchen I found someone.“Grandpa? What are you doing up at this hour?” I asked.“I’m always up at this hour. I’d ask what your excuse was but from the growling emanating from your belly I think the answer is very obvious.” Grandpa Jim said.After we both finished our snacks I looked him in the eye and asked, “We haven’t used any of your condoms in a while. Do you think it’s about time we use one or two or them tonight?”His reply was just a smile and his hand held out for me to take. He. Again he took the tape and wrapped it round the funnel at the top of the base just under neck; holding it firm they wrapped the tape round her head then round the funnel and again around her head until its was impossible for her to dislodge it.They stood back and looked at her as she made silly noises from behind the funnel gag, I started to wonder if they were going a bit to far just to make her drink but she had brought it on herself and I felt a little excited at her being taken down a peg.
