I can remember my older sister staring at me; we were around a friend of Dads, who had a pool and we had been invited over for a swim and a Barbie. My...swimming trunks were a bit tight and seeing my sister in her little bikini had caused me to get hard. I tried to hide in the pool, but once she got sight of it she followed me around trying to get a better look.My sister was almost two years older than me and well built and this was the first time I had seen her in anything so revealing. After. Wendy do you want to fuck in private or in front of Naomi and your mum.”“Here, I want Naomi and mum to watch.”John led her to a couch. He sat in the middle with his cock erect and ready to fuck. He held his arms out inviting her to him. When she was close he pulled her forward so that she was straddling his lap.Without any foreplay he lifted her and lowered her onto his cock.“Is your hymen intact?”“No. I broke it a year ago, fucking myself with mum's dildo. Sorry.”“Don't be sorry. I want this. " Oh, I took that and your gym bag of work clothes out and they're in the living room on the coffee table." Do you want me to come over to the doctor's and drive you home honey?" No. I think I'll be all right. I mean, I can drive okay. It's just... well I have a slight fever and I'm achy all over. Probably just the twenty-four hour flu, but with that walking pneumonia going around I thought I'd better see the doctor just in case."I was worried, Drew sounded like she needed me to be there for. When we were there Ann said, "Your cock is a little hard. I must say that I like seeing you naked with a slight erection." And I like seeing you naked, Anne. That`s why my cock is growing. You said that you liked seeing me with a slight erection. Wait until I start stroking it to masturbate. I think you will like seeing it fully hard." I`m sure I will. Let`s get started, Stan."We did. I was the first to cum and my sister followed soon after. She was panting as she gave herself several orgasms..
