[F]un on a webca[m] site!

My gf and I are a young couple (19 & 20) from the UK. I'm 6"1, slim to athletic build, and she is 5"3, very pretty face, blonde hair, small but perky boobs, small waist but a big bum, very attractive. I've been interested in having sex on webcam but never mentioned it to her. Last night however we were laying in bed before going to sleep and watching funny videos of people on some of those roulette webcam sites, and we decided to go on it ourselves, it was all completely innocent at this point, but already something inside me hoped it could turn naughty. As we were about to go to sleep, we were both already naked and just had the covers pulled up, and as you can imagine a lot of the guys on those sorts of sites, upon seeing an attractive girl in nothing but a bed sheet will try to convince her to take it off. At first she was put off by that, but soon she found it funny, and even jokingly flashed a few of the more attractive guys we came across! I was already hard from her doing that and she noticed, and I asked if she wanted to show off for somebody, and she said that she did.
