First Time Dogging. Part one

I have been crossdressing for many years but mostly in the privacy of my own home. I had occasionally ventured out, mostly by driving to a secluded urban area where I would park up and go for a walk in the quiet streets. This was always done on a dark evening, not that I was afraid of being caught out as a crossdressers As I consider myself to be very convincing when dressed up. On this particular evening I was wearing a long dark coat with a white blouse and a short black skirt well above my knees. A pair of not to high, high heels and black holdups.
My choice of lingerie for that evening was a black bra with matching silk panties with my dick and balls well tucked away. I passed a few people out dog walking and was quite pleased when a couple of the male walkers eyed me up from top to bottom which made me feel quite aroused. As you can imagine being aroused caused its own problem with my cock trying to escape the confines of my silk panties, so it was no easy matter of slipping my hand under my skirt to make a readjustment while walking along.
This was my first adventure of the evening, but my intentions for the rest of the evening was to drive out of town to a well known area for dogging that I'd heard about. Having returned to my car I started driving to the area in question. Having never been before it took me a bit of time to find the place which was a small dirt road leading of the main road and basically into a farmer's field from what I could see. My first view was of numerous cars parked up in various spots round the field, all of them with their headlights on with shadowy people walking to and fro among the various cars.
Being my first time doing this I was a little bit apprehensive as to what was going to happen. Having read about dogging was one thing but actually about to try it was some thing else. So I parked my car in a vacant spot, left my lights on and opened my door. I had only been there a matter of moments when two guys approached me and glanced inside. Obviously happy with what they saw and without a word spoken, they unzipped themselves and pulled out their rapidly swelling clocks. I didn't need an invitation to carry on, I quickly grasped both dicks in my hands and began to masturbate them.
Because of the bad lighting I couldn't make out their features very well but one looked to be in his fifties while the second in his twenties. As far as I was aware they didn't realise they were being jacked off by a crossdressing slut and if they did they didn't care. The younger guy kept pushing his cock towards my mouth while continuing to masturbate them. Needless to say my own cock was now rampant and had freed itself from the constraining panties and was tenting my little black skirt with a good amount of precum staining it.
The young guy now had his cock touching my lips. I tentatively let my tongue taste his precum, swirling it round his dickhead. Things were obviously going to slow for him and with a quick thrust of his hips his engorged penis quickly parted my lips and filled my mouth. He began fucking my face frantically as I felt his throbbing flesh about to unload into my throat. With a low moan from him he began to ejaculate threads of warm sperm Into my mouth. So much filled my mouth that it was seeping out the corner of my lips onto my chin. Meanwhile the other guy I was jacking off at the same time began to unload. His cum splattered over my face running down my cheeks joining up with his friends cum. It was over as quick as it had started, both zipped up, muttered a thanks and disappeared into the night. Meanwhile I was still swallowing cum and wiping the warm liquid out of my eyes reeling from what had just happened. I then realised that my panties were completely soaked, I had ejaculated on myself without realising it.
I felt a bit cheated as I was there to get fucked but as the night was still young I tidied myself up, redid my makeup and dried my pantie area as much as possible ready for the next round.
