When I was fifteen, I lived with my parents. I ofter masturbated in my room, this time was nothing different than any other masturbation session.
I came back from school and went to my room to do some homework for the next day. After doing math for a while, I started browsing my biology book and came to chapter fifteen. This chapter was called 'Sexual Reproduction'. I was very interested in male/female body's and sex, so I started look for some pictures/drawings/etc.
If I check the book now, it's pretty lame. Bad pictures and bad drawings, but at that time I was getting very horny and my cock was swelling up. I then unzipped my jeans and pushed away my boxers to get my erect penis out. While watching the pictures I was stroking it.
After stroking a few minutes, I took off my shirt and turned the page to the next few pictures. My penis was gonna explode then I saw Brenda, the sixteen-year-old girl next door, was watching me. Her bedroom window is at the same floor as mine, only a sidewalk further. I stopped stroking, I was frightened and the good feeling was going away a little bit.
Then my phone rang, I picked up it was Brenda. My heart was bouncing like hell, I couldn't speak. She asked what I was doing, I still couldn't speak. I watched out the window and saw her still watching me and being on the phone. After thirty seconds that felt like an hour, I said, 'I am masturbating' and for some reason I started stroking myself slowly again. She took off her shirt, and I saw her really good-looking boobs she said, 'Maybe this is gonna help you a bit.'
My erection became harder, even harder then before. I started stroking a little faster, and asked if she liked what she has seen, she told me see never seen someone masturbating. Brenda started playing with her boobs, I started stroking faster and faster and moaning little. Not shortly after, I got to the point of no return. A huge white cum beam splattered against the window, a second shot of cum splashed on the window-still.
Brenda still holding the phone, watching me and playing with her boobs told me she was really wet and horny. She undressed completely and started entering her fingers into her vagina. My dick got hard again, she told me she had to cum. I saw a vibe going through her whole body, then she hung up the phone. I did the same, got some tissue and cleaned the mess.
This was my first, but not my last long distance session with Brenda.
