I have crossdressed since my childhood and my wife knows but doesn't like it, which I understand. Up till very recently I haven't felt any attraction towards men and had never had any sexual contact with another man. Well that's all changed a bit... I don't crossdress at home very often, I work in a small office in a provincial town and wait till everyone else has gone home for the night, get changed there and then have a half hour to an hour long walk around town. I then often drive home dressed and change in a field entrance on a back road near my house. I probably do this once or twice a month through the winter months when the dark makes it much easier for me to pass. I am short and skinny and find it reasonably easy to pass. Crossdressing isn't an overtly sexual, or not a purely sexual thing. I often just walk around, get changed near my house and that's it, not an erection in sight. The other evening after a nice stroll I was driving home past a local dogging spot and there were a few cars there with their lights on. For a thrill I turned in and drove to a quiet corner of the carpark and turned the engine off and sat there. "What the fuck am I doing?!?" I kept thinking but at the same time I knew exactly what I was doing. I was wearing a long padded coat, a midi-skirt, hold-ups, nude stilettos a cream roll neck jumper and a padded bra. My hair is long anyway but I had brushed it out and I was wearing a nude-ish lipstick. I got out of the car and took off my coat, put it into the back of the car and got back into the driver's seat again my heart pounding. There was some activity in another part of the carpark but it was very quiet where I was and I started to relax. Then a car pulled in beside mine. I could hardly look over I was so nervous, I couldn't work out whether to just drive away but I was in such a nervous state I don't think I could have safely done that. I glanced over, a man was in the other car, late 40's his interior light was on and he was looking at me. I smiled very nervously and then put my face in my hands. He got out of his car and walked round to my window and said hi and asked me if I was here to play. I opened my car door and found myself saying, "yes, but only oral." He looked like he had hit the jackpot and started tugging at his belt and getting his cock out. I couldn't quite believe it had all escalated this fast! I was sitting with my legs out of the car and he started to rub my stocking clad legs as he wanked and I just sat there like a lemon. He started to feel up my thighs and I parted my legs a bit and suddenly felt incredibly turned on. His cock was hard already and the tip looked like it was leaking pre-cum and suddenly I knew I had to taste it. I reached out and took hold of his hot cock and started to slowly wank him, he groaned and shuffled towards me so his cock was right in my face and it seemed like the most natural thing in the world just to take him in my mouth and so I did. His big hot slippery cock head was in my mouth and it felt so amazingly good. I sucked him and swirled my tongue over him, he gave another loud groan and held my head in his hands and started to gently pump as I sucked and wanked his shaft. I tried to take him as deeply as I could without gagging and slurped and sucked on him for maybe two minutes, my hand was really wet with my own saliva and that helped. Every now and then I would stop sucking and wank him and look up at him and rub his cock over my lips and face. This was a dirty, dirty blowjob. I could taste the bitter pre-cum really strongly and his cock was iron hard and I knew he wasn't going to last another 10 seconds of this, "I'm going to cum!" he grunted and as he said it he started to cum, it felt like so much in my mouth and I swallowed as each pulse of cum squirted into my mouth. When he finished and his cock was softening he took a moment to slowly rub his cock over my face and groan again. "Thanks" he mumbled and he bolted back to his car! I got back into mine and followed him out of the carpark then drove the wrong way so as not follow him. Driving home I just reeked of cum, the taste in my mouth the smell of it on me. I turned on the interior light and looked at myself. I looked such a sex wreck. Just incredible and I had planned nothing. I have absolutely no idea if I will ever do it again but I don't regret giving cock sucking a try!
