I was attending an interstate conference with a work colleague. She and I were staying in seperate hotel rooms for a week. We'd been working together for a while but weren't really close. By the second last night of the conference we'd started to develop a friendship and we ended up in her room watching TV together because we both said we wanted to watch 24.
When it ended she took the remote and channel surfed. After a bit of surfing around chatting about TV we ended up watching porn. She said she'd never seen it and she made lots of jokes about it. After about 15 minutes of her joking she asked me if it was getting me aroused. I told her it was and she said I could jack off if I wanted to. I was kind of embarrassed but rock hard. She said it was no big thing, it was like she'd told me I could take my shoes off she was so casual about it.
I masturbated into some tissues while she pretended to watch the screen but kept shooting me furtive glances. The next day at a break in the conference she told me she was looking forward to watching me Jack off again that night. So we ended up in her room again only this time she started watching porn immediately and instead of just unzipping myself and wanking I sat there with no pants on taking my time and she watched the whole thing. It was one of the best orgasms of my life.
This year the same conference is on again and I'm hoping the two of us get to go.
