My Girlfriend's Best Friend

One day I was walking down the street to my girlfriend's best friend's house. Her name (which I've changed) was Ella. Well, I knocked on her door to talk to her, but no one answered. But I KNEW she was home because I'd just seen her get off the bus. So I went around the back of the house and peeked in the window.

And there I saw her between her window blinds. She had her hand down her jeans and it was very obvious what she was doing. Her eyes were closed as I saw her hand working away at what she was doing.

She looked so innocent but also so sexy! I felt bad for watching, but I was also harder than I'd ever been! So, right there in her back yard (which is very private, no way anyone could see me) I stood below her window wanking off.

I just rubbed up and down, imagining her instead of my hand. I still kinda feel bad for not imagining my actual girlfriend, but...

Right before I would have come, I heard the window open. She was looking down at me in horror and embarrassment. We just kinda stared at each other for a second, and her face was deep, deep red, and I'm sure mine was too. Then I sputtered and apologized, and hopped on my bike and pedaled home.

Oh MAN, that was an awkward minute! Whenever she sees me, her face turns deep red again and she avoids me, but that memory of us pleasuring ourselves, just a wall away from each other, is one I'll never forget. And it's one that has fuelled fantasy for many of my lonely nights...
