This is a new level of wrong

"I was at a works party a few years back and everybody was getting incredibly drunk except me as I was driving. I decided to leave early as I was getting somewhat bored, on the way out I bumped in to one of the girls from in the office, she was REALLY HOT and ultimatly plastered, struggling to even stand. I quickly had a look around the lobby of the hotel where the party was and realised that nobody was in site so decided I would offer her a lift home, hoping on the way she would 'try something on'. Well, she didn't try anything in the car but did invite me in to her house. When we got in the house and started to drink coffee on her sofa we started to kiss and she went down on me, however half way through she fell asleep. My member was still standing to attention and I was somewhat sexually frustrated so I 'finished myself off' all over her face and quickly left. She was left absolutly covered if you know what I mean.
The next morning at work I saw the girl crying and talking to a group of other workers and shat myself, even more so when I was shouted to go over by one of the workers and he had a concerned look on his face. I stood and listened with a fake shocked look on my face whilst the girl told the story of how she got trashed the night before at the works party and had no memory of getting home and worse still how she'd woke up the next morning on the sofa covered in seamen. Everybody offered sympathy whilst I stood and reflected back on the event feeling like a porn star.
Did I feel guilty, yes. Would I do it again given the same chance, hell yeah it looked great when I splashed her face and watched it dribble from her chin!

I have problems I know, it's not like it'll happen again.

Yes, I still see the girl in the office"
