Caught by a Female Schoolfriend

When I was 16 I always had about the same amount of male and female friends, so going to a party or a sleepover at female friends of mine wasn´t really a big deal. This time though we (2 male friends, one female friend, the girl where we where staying and me) did a movie night! We had some Pizza and watched some movies until it was about midnight when all the others had to go home and since they where living pretty much around the corner it wasn´t a big deal! I was living abot an hour away from this place so i had already asked if i could stay on the couch for the night, which wasn´t a big deal. When the others had left we decided to go and watch another movie! We switched into our pyjamas and continued started watching another movie! I could clearly see that she wasn´t wearing a Bra underneath which caught my attention and although i had never thought of her as that kind of friend it got me arroused! Unfortunately the movie had some very nice topless scenes, so that didn´t make it any better. Luckily I was covered up by my blanket so she couldn´t see my hardon. After the movie was over at about 1:45 am we decided to go to bed! She went into the bathroom and got herself ready. After she was done, she told me goodnight and walked into her room. I also went to the bathroom and got myself ready for bed! After returning to the couch i could´t fall asleep so I turned the tv back on and started switching through the channels, when i found one of those softcore porn late night movies! Since i had been horny all day i had an erection quite instantly, sat up on the couch, tuned down the Volume to the minimum and started playing in my pants! After about 5 minutes i felt that i was getting closer, stood up, pulled down my pants and prepared a tishue to cum in! But it turned out very different! Just a few seconds after i had gotten up i heard the floor beside me creaking and at the same moment i heard her say "Oh my god, what the fuck?" I immediately pulled my pants up sat down and appologized about a hundert times! She was standing in the hallway with her mouth open, and a glass in her hand not looking very pleased! It was sooo embarassing! Luckily she just just said, go to the bathroom if you want o wank, walked into the kitchen, got herself some water and walked back into her room! Of course i couldn´t help it and had to finish off, but somehow i wasn´t that much of a turn on. The next day started quite awkward when she walked into the living room, saying good morning as nothing had happened! Me still embarassed just saying, good morning, didn´t change the weird situation. After some time i decided to appologize again and told her why i was so horny (The movie and so) and that i hadn´t done it for a few days and that i wasn´t thinking! Luckily she just looked at me and said: "Next time just don´t wank in the middle of my livingroom and don´t let yourself get caught!" Fortunately she didn´t tell anyone and unfortunately we never talked about it again!
