My sister and I were by ourselves for some years for both our parents worked in the city and would drive for half an hour to the RR station then spend one hour on the train to their company in midtown. This was more than three hours round trip. Sissy, at 16, was over one year older. Every Wednesday, Margie, who was the around 21, would show up to give Sissy piano lessons. Margie was tall and really good looking. After half a year of lessons, Margie and Sissy would go up to Sissy's bedroom and I would hear funny sounds coming out.

At first I thought one or both were sick. Then I heard giggling and moans. After some months of this activity my curiosity got the best of me and one Wednesday while the sounds were fairly loud, I opened Sissy's door and saw them naked in bed, with Margie's face buried in Sissy's crotch and Sissy's into Margie. I was totally confused, knowing nothing about this activity. They saw me standing there but kept doing it, moaning and oooohing. I asked if all was o.k. (DUH) and Margie stopped and said, "Penny we're just making love, there's nothing wrong." I stood there and watched them. I felt my body tingling all over, then asked if I could also "make love". This time Sissy answered and said, "No, it's our thing."

Then, Margie stopped and sat up, nude, where I noticed her beautiful teats where I was flat as a basketball floor. Margie said, "When you are 16, you can make love with us if you want. Is that o.k, Sissy?" Sissy volunteered a feeble, "I guess so." That was just over a year later but I wanted "in" ASAP and on my birthday, Margie came unstuck from sissy for a while and hungrily ate me out, sending me like a rocket up to heaven. After that, a lot started happening in my life.
