I work in a large company (I won't say the name as that'll give the secret away), there must be 2000 employees on my site. Last Monday I was sitting in the restaurant with a friend, Tom, having lunch when he pointed out this pretty girl and said 'what do you think of the new girl in my office? She started last week', she looked to be in her early 20's, about 5' 2", slim build with pert little tits and a nice arse and jet black hair. I said 'she looks a bit of alright'. Tom replied 'don't try it, rumour has it, she is a he. Or was a he' I said 'bollocks, there's no way that's a guy' Tom laughed and said 'bollocks, exactly. It apparently still has them' We finished lunch and left. Tuesday was pretty much the same, me and Tom chatting, when 'the girl' came walking towards us, Tom said 'make your own mind up over what I said yesterday' and as she reached our table, he called her over and introduced me. He said her name was Sofia, she smiled and said 'hi' with an accent (there was no hint of her being a guy, and I thought that Tom was having me on). She sat there and chatted, after about 10 minutes Tom said 'oh fuck, I gotta go I'm late for a meeting' and as he left he said 'let me know your thoughts about what I said'. Sofia was very pleasant, she said she was from Italy and had been here about 5 years, we chatted about things she liked to do, but said that she didn't get much chance as most of her friends had moved back home. I was beginning to think Tom was having a laugh, or was trying to put me off this girl - I thought he had designs on her. Just before I had to get back to work, I said 'look, if you're not doing anything this Friday, perhaps we can go for a drink and a movie, as your friends have all deserted you'. Sofia said okay and we made a time and location. The rest of the week at lunch Tom was trying to get out of me what we had chatted about, I told him about where she was from and about her friends, but never told him about the date. On Friday evening, I met Sofia as planned, we went for a meal and a drink, we forgot the movie as there wasn't anything we fancied. At the end of the evening, I drove her home and she invited me in. Up in her flat, we sat there chatting, things got a bit quiet so I said 'lets put some music on', she put on a CD of Ella Fitzgerald - one of my favourites, she said she couldn't believe it as it was her favourite. After a few minutes, I said 'stand up' which she did and we began to dance around her lounge. The next song slowed right down and I lent forward and kissed her, she kissed me back and within a few minutes we were on the sofa kissing heavily. My hand began to rub her tits through her dress, she didn't object. A few minutes later I undid her dress at the back and she slipped her arms out, her lovely pert tits covered by her bra. A minute of so later her bra was off and I was sucking at her nipples. I pushed her dress down further but she said 'no' and pulled her dress back over her tits. She said 'I'm sorry, I can't', I just said 'not to worry', Sofia then said 'you don't understand, it's not that I don't want to, I don't want you to see me naked' I said 'I understand' the she said 'you won't believe me' I asked 'is it anything to do with the rumours someone is spending at work' She sat there, her head low and said 'yes'. I just said 'you've not got anything that I haven't seen before' Sofia replied 'I doubt that'. I said 'so it's true, you are pre-op' She turned and looked at me and said 'yes, it that a problem' I lent forward and kissed her again, she kissed back and within a minute of so she was sliding out of her dress, exposing her lovely pert tits again, her black knickers doing a bad job of covering her erect cock. I slide my hand down her stomach into her knickers and began to rub at her cock, she moaned. Within a minute we were both naked, she was rubbing my cock then she lent over and slowly slide back my skin to expose the juice covered bell end. She licked and sucked at my cock. After a few minutes, I lifted her up so that she straddled my hips, slowly lowered her onto my hard cock, the tip slowly pushing into her arse, she lowered herself right down onto me and slowly started to ride me, as she did I began to slowly wank her cock. Within minutes I was shooting my load into her arse as she came all over my stomach. When she collapsed onto me, she asked if I had minded that she was a pre-op, I said 'If I had, then I wouldn't have fucked you.' I then said 'the best of all worlds - tits to play with, cock to suck and arse to fuck' We repeated this several times in the night and on Saturday morning before I left and said we'd see each other again.
