New life in London

Okay, so I gave in to the lure of the great evil, money, and took the job in London which I couldn't really refuse. Can you believe I was headhunted? So today, being Friday, I'm off early and preparing to get ready to hit the town tonight. I just thought i'd run something past you, see what you think. I'm 29 now and I'm afraid I might be regressing into a teenager. My mind is often so fulled with bizarre sexual fantasies that I really think it's time I grew out of them. I think about sex far too much. I was on the tube today (god it was hot!) and , relaxed as i was at the end of the week, I turned to thinking about exposing myself on the train. Perhaps just parting my legs with no knickers on so the attractive business guy opposite could see my shaved lips and a little bit of glistening moisture. And I got quite turned on just thinking about it (of course, I wouldn't dare do it). Every time I get even a little turned on, I get wet! It can be quite uncomfortable, knowing there's a damp patch in the knickers and I'm far from home so I try to think about something else but it's too late, I'm on the way to full sexual fantasy. I imagine I'm on the train with my legs well and truly parted and the guy opposite is just staring at my vagina. He starts to get an erection; I can see it through his trousers. Then I imagine almost everyone else gets off the train but the others are far enough away so I bring my legs right up and expose myself to him fully; he can see right into my wet hole and I reach down and pull the lips apart. I love the thought of a complete stranger looking at my wet vagina. I'm wet now just thinking about it but at least I'm at home now, ready to jump in the shower. Is it time I gave up this sort of thing? What do you think?
