Hi, my name is Charles. I was sixteen years old as was my step-sister Janice at the time this took place. My sister had three of her girlfriends over, Lynn, Sandra, and Melanie. All of them had been in our pool, swimming. They had got out of the pool and onto the deck to sun themselves in their bikinis when my friends Larry, John and I came out for a swim. This all took place in early July, almost ten years ago.My step-sister’s friend Sandra was the only one of the girls staying overnight, since she lived some nine or ten miles away and the girls had plans for the next day, wanting to get an early start on their shopping spree at the summer sales at the mall.Everyone else lived just a short walk away so they all left late that afternoon so it was just us three for dinner with mom and dad. After dinner, my sister and Sandra went upstairs to her room to do whatever, while dad went into the den to watch some TV and read his newspaper. I stayed downstairs helping mom clear the table and wash the dishes. After we had finished cleaning up, we joined dad in the den, Escort Yakacık watched some TV and just sat around talking. The girls had changed into their pajamas, robes, and slippers and had come back down to join us in the den.We spent the next few hours talking, drinking some sodas, eating cake, and having a good time as a family. Then at about 10 pm, our parents decided it was bedtime so we went up to our rooms.Sis’s and my rooms are upstairs adjoining but with a shared bathroom in-between. She and I are often in there at the same time so we’re used to seeing each other in the nude but thinking nothing of it. There is a lock on both doors, but we seldom use them. We don’t let mom and dad know this happens though as we both realize that they’d be against it.Sis forgot to tell Sandra about the locks and so the inevitable happened. I entered our bathroom from my side completely nude to take my shower where Sandra was already standing naked and just about to get into the shower herself. Wow! I thought to myself. She’s gorgeous. Atalar escort She had delicious, full, round, firm breasts, erect nipples, a smoothly shaven pussy, and a bubble ass too boot. I took all this in so quickly, without realizing what a pervert I must have seemed, scanning her nakedness like a photocopier, burning the image in my mind for later use.Finding us both at a loss for words, we stood there dumbfounded and unable to speak for a few moments whereupon I suddenly said, “Want to try one together?”To my surprise and amazement, she stood there staring at me with my erection fully on show, and then quietly, as if this was normal, replied, “Okay! Why not!”After all, you look as if you need some help with the washing – “You can wash my back and I’ll wash yours,” she said.We climbed into the shower together where we did indeed bath each other – completely, although not to completion, as it were. We then dried each other off and she slipped back into her PJ’s and returned to sis’s room where I heard them talking. She Kadıköy escort bayan asked Jan if they could invite me in there with them for a while.My sister said okay and came into the bathroom where I was still nude brushing my teeth. She asked me if I would like to come into her room for a while to join them both.“Oh, by the way, there’s no need for you to get dressed either since we’re gonna both be naked too,” she said.I didn’t need to reply, just grinning and nodding like an idiot as I finished brushing my teeth.Sis was getting undressed and Sandra was already nude, sitting on the bed and pointing to where she wanted me to be so I’d be in between them. She started slowly stroking my erect penis with her soft, warm hand. Sis joined us on my other side where she also began stroking me. I began fingering both girls’ pussies, first with one finger and then slowly adding a second. They were both moaning in pleasure as I continued pushing in and out very gently, sometimes fast and sometimes slow. It seemed to do the trick as they both had several orgasms and it was marvelous to have two girls Cumming in my hands at the same time, even if one was my own step-sister.We spent about an hour masturbating ourselves as well as each other. All three of us were squirming, breathing hard, and moaning happily; it was one of the most fantastic evenings ever.
