After reading all the stories, this has been a long time in coming
The whole situation started with innocent text messages. Over christmas holiday I started texting the girl I had recently been hooking up with. She is a pretty girl, taller, but an athlete with smaller boobs and a very wet pussy, at times.
One night she and I started texting about how much it sucked that we were so far away and couldn't hook up because we were both so horny. Eventually the topic of masturbation came up and she mentioned that she had left her pink vibrator at school and was missing it very much. I told her how seeing a girl masturbate was a huge fantasy of mine and how that is typically how I get off. We eventually started exchanging pictures and videos over our phones to aid in one anothers masturbation. I would get random texts in the middle of the day saying things like 'i'm so horny and my pussy is so wet I wish you were here to lick my dripping pussy.' Naturally this would turn me on and I would get hard. It seemed like in no time she had me with my dick out telling her about every long stroke. She would tell me how many fingers she was using and it was very hot.
Once we got back to school I pushed the issue of wanting to see her masturbate being that he 15 second clips from my phone were not enough anymore. One day when we were hooking up I really started to push the issue, but she was shy about it. So I started to kiss her neck and suck on her nipples as I ran my hand all over her pussy. Once she got really wet I took her hand, which was wrapped around my cock at the time and slowly guided it over to her dripping pussy. Slowly she started to play with her clit and show me how she pleased herself. As I sat there watching her circle her clit with her middle finger I couldn't help but start to stroke my cock. As she started to slide her fingers deeper and deeper into her pussy, I started to stroke my penis faster and faster. Once she started to moan from the pleasure I couldn't take it anymore. I managed to get 'cum with me' out and we both sped up just enough. Spurt after spurt of white milky cum spewed froth from my throbbing cock as I watched her writhe and moan in pleasure.
Once we were both done I told her how amazingly hot it was and made her promise to show me how she did it with her pink vibrator... i'll be sure to let you know how that one goes too
