Cumming of age!!

One weekend my mother in law was out of town. Before she left she ask me to
go by the house on occassion to make sure leslie; My 15 year old sister in law
was okay. Leslie was very attractive for her age. She was developing into a
beautiful young women. Friday night on my way home from work, I stopped by the
house to make sure everything was okay. When I walked into the house I could
here the tv but it wasnt that loud. When I walked up the stairs I could hear her
moaning very lightly. I walked into her room and peaked around the corner only
to see her on the bed playing with herself while watching one of her mother's
porno tapes. Seeing her hairless vagina, me immediately got a hard on. I backed
out of the room without making a sound. The thought of me putting my 7 inch
penis in her excited me, even though I knew it wasnt right. So, I took a deep
breath and walked in appearing to be shocked and asked her what was she doing.
She jumped up when she saw me and tried to turn the vcr off. I told her that it
was too late for that. I asked her were did she get the tape. she told me that
her mom had a couple of tapes under her bed and she took one wanting to see what
they were. By leslie still being a virgin, I asked her if she had ever had sex.
she told me no but guys had tried to get her to have sex and suck their cocks,
which she said that she did neither. I asked her if she liked what she say on
the movie. she did. Knowing it wasn't right I noticed that the tape was showing
a man getting a blowjob. She asked me if all men were large like that on the
movie. This was his chance. I told her that I would show her what they look like
up close. I walked up to her and pulled my pants down. My 7 inch startled her. He
told her she could touch it and play with it. She grabed it, saw a lady deep
throating the man on the movie. I told her to first kiss the head, which she did
and I almost came instantly. I then told her to open her mouth so I could slide
my cock in her mouth. With it opened wide I slide my cock in her mouth.

The feeling of my shaft gliding against her tounge, I I almost instantly came.
She then began to mimick what the lady was doing on the movie.
She grabbed my dick with one hand while sliding her tounge up and down my cock.
I told her that soon I would be cumming and she had to swallow all of it.
I grabbed the back of her head and shot my load all into the back of her
throat. she swallowed it all. Now the movie was showing the man licking the
ladies pussy. She asked me why the man was doing that. I explained to her the
the women pleasured the man and now the man was pleasuring the women. I told
leslie to lay on her back and I would let her experience what she was seeing on
tape.
