I Loved Watching Her Having SexI've always been very close to my older sister. She taught me a lot about sex, my body and just having a good time.
When she started having sex I was naturally very curious to see what it was all about, so I would try to sneak into wherever she was getting ****** by her latest conquest, but I failed every time as she's very alert.
One weekend our parents were out of state and she invited a friend over. They made out in front of me, then disappeared to her room. They didn't close the door fully, and I walked by every minute or so and peek through the gap. After a few minutes she called out "For God's sake Ally, stop that, you're distracting me! Come in or close the door". I was in there like a flash. It was awesome to see up close how her ***** lips moved with the guy's **** and how her little **** jiggled a bit.
It obviously got me very horny so I was fingering myself furiously while watching them. I think I had 3 ******* to her one!
I didn't join them, but a few months later we started having three and foursomes.
