Masturbating With Sister

The following is one of the most exciting masturbating experiences that I
have ever had. I am happy to share it with your readers.

It happened with my fifteen year old sister. I'll call her Ann (not her real
name). I was 14 at the time. Ann and my older sister, Vallery (also not her
real name), age seventeen, together with an older neighborhood boy, Jerry,
came to me one day and asked if I would join them in a little dalliance they
were planning. They had apparently agreed to undress to show each other
their sex organs. They needed another boy. I couldn't believe my good
fortune. This was a dream come true for me. I readily agreed.

We proceeded to a large, vacant lot (about two acres) with a lot of tall
weeds for concealment. When we got to a good spot Vallery said to me and Ann
that we were to stay there and that she and Jerry would go off to another
spot. We were pairing, I guess. I think it was Jerry's idea. He apparently
wanted Vallery to himself.

After they left, Ann pulled down her jeans and pink panties exposing a
beautiful pussy with short, brown, silky pubic hair. I felt a thrill go
though my body as this was the first time I had seen a female's sex organ.
After she pulled down her pants and panties, she invited me to pull down my
pants and shorts, which I did. My cock began to rise until it stood straight
out. We looked at each other for a while each enjoying the view and lewdness
of it all. She told me that her pussy was where babies came from. This I
already knew.

In a minute she pulled her T-shirt up over her titties. She had no bra on.
Her tits were beautifully round with pointy nipples that stood straight out.
She pushed her pants and panties down to her ankles exposing herself from her
tits to her ankles. She asked me if I wanted to touch her. I reached over
and lightly touched her pubic hairs. She spread her legs as far as the
pants, now at her feet, would allow. This allowed me to put my hand between
her legs. I felt a damp slickness. She started to move her hips in a
circular motion telling me that she wanted me to rub her, which I did. She
reached down and directed my fingers to her inner pussy lips. The slick
juices there made rubbing her easy and exciting.

After awhile, I put my other hand around my now hard cock and began to move
the foreskin back and forth over the cock head with the two-finger method. I
had masturbated before so was familiar with what to do. There we stood, me
with my fingers gliding up and down her slit and the other hand on my cock.
She was enjoying every minute of it. Her pussy and inner thighs were awash
with precum as was my cock. I began to feel a climax coming so I pumped my
cock faster. In less than a minute, my cock was squirting cum which I
directed onto her bare belly with some dripping into her pink panties. This
was all we had time to do as we heard voices. It was Vallery and Jerry. We
hurriedly pulled our pants up and acted like nothing had had happened.

This is a most exciting memory. My sister and I have never spoke about this
experience since. We are now adults and I often wonder if she remembers. I
would gladly do it again with her, even today. I will never forget and often
masturbate to this memory.
