In college I worked as the computer lab monitor. Which basically meant I refilled the printer paper and occasionally helped someone when one of the computers acted up. Most of the time I sat in the little office right off the lab with the door closed. There was a large glass window between the rooms but it was oddly set a little high so when you sat down all you could see of someone was from their head up. One night I was "working" a girl I knew stopped by to hang out with me. We had been flirting off and on for weeks and had already hooked up as part of a dare she was given (story for another time). She locked the office door when she came in and I looked at her before she said she was given another dare and she needed to suck me off. I sat there in shock for just a few seconds before she knelt down between my legs while I was seated. I looked out into the lab but there were only 2 people there so I shrugged and let her undo my pants and pull my cock out. She wasted no time as she went down on me so quickly I grabbed the desk to keep the chair I was in still. She stopped briefly to pull her tits out of her low cut shirt and then went back to the very sloppy blowjob. I kept looking out to see if either of the 2 people in the lab noticed anything but after awhile I didn't care and focused solely on her sucking me. She would take me deep in her mouth and lick her tongue up and down my shaft as she lifted her head up. She she got to me tip my legs jerked as her tongue rubbed right under the front of it and she looked at me and smiled before sucking hard right there while licking the sensitive spot. I could barely keep still while she did this and I felt myself getting closer to cumming. She kept up the pace and the stimulation under my tip when I warned her I was about to cum. She waited until I started in her mouth before pulling me out and jerking me all over her tits. When I finished I asked why and she said she had to deliver proof she completed the dare (I had creampied her during our first hookup). She tucked her cummy tits back into her shirt and kissed me before heading for the door and telling me she'd be by my room later. That woman is the reason I have a public sex kink.
