Here's an experience that I had several years ago, before I was married, with a female co-worker who happened to live across the street from me. Her name was Carol and she had a quiet and subdued, yet extremely direct way of letting a guy know what was on her mind, particularly if it involved sex. Although Carol and I eventually ending up sleeping together a couple of times, this incident occurred before we got to that stage in our relationship.
At the time (I was 29) I was the only male in an office of about 12 women and I was really enjoying the attention. Although I hadn't slept with anyone of my co-workers at that point, there was lots of sexual teasing going on between Carol and me, most of it having to do with masturbation. Neither Carol nor I were dating anyone at the time so we both had lots of sexual energy to burn off.
Anyway, over several days our conversation got down to imagining what it would feel like to masturbate in front of someone of the opposite sex. We both admitted to our "secret" desire of wanting to do this, although Carol felt she'd be too embarrassed to expose herself this way in front of a guy. I, on the other hand, was somewhat of an exhibitionist at this point in my life so I pursued this topic further in the hope I might be able to live out one of my long-held fantasies-stripping and beating-off in front of a woman. For her part, I think Carol sensed she had tapped into a fantasy of mine and, rather than try to re-direct the conversation, she kept asking leading questions, which only encouraged me more!
Taking a deep breath, she was after all a co-worker who I didn't know all that well, I eventually told her more about my fantasy: my desire to "perform" in front of several women, not wanting anyone else to participate and my willingness to do whatever I was directed to do by those watching.
Well, her reaction was both more and less than I expected. Rather than run screaming out of the room, Carol just looked at me for a long time and said that she found my fantasy to be quite a turn-on.
In telling her, of course, I found myself getting horny at the thought that this really might happen after all. I didn't quite know what to say next, having just opened myself up to a colleague I'd only known for a couple of months. Besides, we were having this conversation in her office, which was open to anyone who might choose to pop-in and say hello. Anyway, the mood was broken by the ringing of her phone and our need to get back to work.
Carol and I didn't get an opportunity to talk again that day or the next. As it often happens when you've just shared some very intimate piece of yourself with someone, it's very hard to re-connect with them on a more normal basis.
Naturally, I was afraid that she had re-considered what I had told her and decided I was creep and a pervert and that she was purposefully staying away from me. As a result, I was concerned (and intrigued) a few days later when Carol left a note asking me to come by her place about 8 in the evening so we could talk about what I had told her.
