She put her hand on his face as his fingers rubbed the front of her knickers, as she moaned he rubbed faster, the faster he rubbed the more she moaned... Then out of the corner of her eye she saw someone, there stood watching was one of the bar waiters, he was 19, slim, and dressed in the same uniform, she beckoned him to come over and he did.As he approached Donna who was half laid on a bench with the barman’s hand up her dress, she reached out and rubbed the front of his pants, it was within. She said they would sit in silence listen to the music and she would then move her hand to touch her b/f mate. Her b/f knew what she was doing but the mate didn’t know the b/f knew he was being felt up.I said I wanted to try it and she said there was a guy at her works in the stores who we both knew. She said we could meet him for a drink and see how it went.I was at work the following day when my g/f text to say we would be meeting Ian that night for a drink.I only knew Ian from a works event. I feel a big poopy comeing on she smiled.Grandma said me too been kinda holding it waiting for someone to get interested.she looked at me.Heck grams I am always interested.Wait for a couple minutes Im going down to the basement be right back.gram got up and headed downstairs.Mom let another big fart and I knelt down to sniff it all up.It was a nice heady aroma not spicy and sharp like a wet shit but more of a firm shit smell my favorite. Gram appeared about 2 mins later carrying a hospital. Then he ran out the door, and I didn't see him for a while.By the time we were all naked, Dad's penis was getting big and hard, too. I'd seen penises in pictures in art books before, but not hard ones. Dad asked me if I wanted to touch it. "Sure," I said. Mom told me how to touch it and stroke it and make it harder. "Not too much, though, or you'll make him jizz." What's jizz?" I said. I had never heard of that."Jizz is what comes out a boy's penis when he's really, really excited," Dad.
