Thank you for all the comments.  I know what I did was risky, but that is the point.  Most of us do risky things, what about skydiving or open water swimming?  Some do downright dangerous things, it's the fear that makes us feel alive.  So fuelled by a cocktail of adrenaline and estrogen, with a dash of testosterone, it was only a few days until I wanted not just a repeat, but an escalation.

Dare I go by myself at night?  There was only one way to find out.  If something was going on, I would stay.  But I would not leave the car and the doors would be locked, I would just give them a show.

The turning was even harder to find in the dark and when I did, I found that the road had been blocked by a huge mound of what I think was sugar beet.  I knew from previous visits that the other end was difficult to access and with one end blocked, no escape route in case of an emergency.  Slightly crestfallen, I drove home.  I soon found another location on line and checked it on Google Earth.  It was a pukka car park for a small nature reserve.  During my lunch break, I investigated.  It was busy, mainly with dog walkers.  An evening venue only then.

I went back after the sun had set.  It was a Friday, apparently the most active day.  It was a very different place at night.  There were seven or eight cars parked, with a group of mainly men, but a few women, clustered around one of them.  They watched me drive in.  I parked opposite and watched, their attention soon returned to what they had been watching, and sure enough, men had their cocks out wanking.  Curiosity overcame fear, I got out and walked over, again they stopped and watched my approach.  They seemed surprised to see a woman by herself  but politely moved so that I could see into the car.

It was a big estate car.  The rear seats had been folded flat.  In the back, was a couple, fucking.  The girl was on top, with her tits out.  The man's hands were on them, she was riding his cock.  They didn't break stride, the man suddenly bucked up into the girl, very obviously shooting his cum into her.  The crowd dispersed.  One of the female spectators spoke to me.

"First time?"

I nodded.

"Welcome," she said.  "Were a bit sparse on the distaff side.  Where's your bloke?"

"Long gone," I said.  "I'm on my own."

"Good for you," she said.  "You've picked a good bunch, we look out for each other, you're not in any danger.  There's no pressure to perform and the women call the shots, if you'll pardon the pun."

She went on to explain that I was free to just watch, to join in, or if I preferred, a solo performance, adding;

"The guys love to watch a woman wank."

The group had moved to a picnic bench, where one of the other women was giving blow jobs.  We went over to watch.  They all seemed to know each other, giving encouragement to both the sucker and the sucked, using their names.  As we watched, the woman pulled her face away from the cock she was sucking and finished him by hand, directing the shots onto her ample tits, which were hanging out of her top.  Another man stepped forward.

I was gushing into my gusset, it could be me sucking cocks.  I had not intended to do anything other than explore, but had come prepared.  I was wearing my flashing dress from my debut, but this time with knickers under it.  And I had brought my trusty towel.  I said;

"I could do a solo, if that's okay, then see how it goes."

The duty cocksucker was on her third.  We moved closer and watched her finish the job.  This time, she swallowed.

My new friend, Kate,  said;

"We have a possible new member fellas, she'd like to do a show.  All in favour?"

There were sounds of agreement.  She said to me;

"You have the floor.  Enjoy."

I returned to my own car, lowered the seat as before, put the towel in place and went to sit on it.  Then I thought;

"Fuck it."

I undid my buttons and threw the dress onto the back seat.  My knickers followed.  There were some comments, building site talk;

"Nice arse."

"Good tits."

"Would you like help?"

Naked now, apart from holdups.  I sat before I fell, my legs were like jelly.  I pulled the door closed and locked it from the inside, I didn't want this going any further than a solo performance.  I also kept the windows closed, having to wash spunk from my lovely new car had been enough, I didn't want it shooting on my upholstery.  That didn't go down well, drawing requests to wind the windows down.  I ignored them.

I was terrified, but defiant.  I would give them a show to remember.  I started by playing with my tits, sucking and licking my nipples, then very slowly moving one hand down as I parted my legs.  I began by pushing two, then three, then four fingers into my cunt, no additional lubrication required, and finger fucking myself.  Then, still stuffed full of fingers, I did my favourite of strumming my clit with the middle finger of the other hand.

There were faces at every window, and just out of my sight, cocks being wanked.  I came explosively, crying out and bucking up from my improvised wanking couch.  Okay, I embellished it a bit, but it was a good come.  But I wasn't finished, I had brought my biggest dildo.  I slowly inserted it into myself.  It's a tight fit, usually requiring lubricant.  But not tonight, it seemed to go in easily.  I began to fuck myself with it very slowly.  It had never felt this good, was that the stirrings of another orgasm?  I increased speed, this monster was hitting all the right spots, I came again, screaming and convulsing.

When my eyes swam onto focus, Kate was shooing away the crowd.  There was fresh spunk trickling down all of the windows, even the windscreen.  Kate motioned me to wind down my window.  She nodded at the cum and said;

"One of the hazards, if you do it in the car  you have to wash that off.  That's why we use the picnic tables."

She was the only one left, the others had wandered off to watch Ellie, who had been sucking cocks until my intervention, and had resumed.  I got out of the car, Kate helped me to put my dress back on.  I was a bit unsteady.  She said;

"They loved your performance, it was spectacular, will you be joining us next Friday?"

I said that I would think about it.

"Please do," she said. "I think that I can safely say that every man here would love to fuck you.  My husband certainly would, and I would love to watch him fucking you, from behind with those big tits swinging."

"They're not that big."

I protested.  She lifted up her teeshirt and displayed hers.

"Bigger than these," she said.  " My husband says these dont give him a good tit fuck."

"Which one is your husband?"

I asked.  She looked over to the group.  Ellie was now bent over a picnic table, with a cock in her mouth and another pumping her from behind.

"The one fucking Ellie," she replied.  "We use condoms for fucking of course, pity because he could come for England."

We watched the show until he grunted and came.  I said to Kate;

"If I do decide to come back, tell him he can be the first to fuck me."

I drove away with that in mind.  Of course I was going to go back.  I showered when I got home, then slipped into my lonely bed, wishing that I had a cock inside me right now.  A real one.

The following evening, Saturday, I put on a good, sexy dress and took a cab to a nearby hotel.  My intention being to get myself fucked.  I failed.  I was approached by only one man, who I really didn't like the look of.  I wasn't that desperate.  So it was just me and my fingers.  Again.

 I was back at that same car park early.  I was the first. There were a few dog walkers just leaving.  Kate was the next to arrive, she introduced me to her husband, Bill, who said;

"You're going to be in demand tonight, if you're up for it."

I had decided previously that this would just be another fact finding mission.  But if I felt the need, I would get myself fucked.  I felt the need.  As promised, I chose Bill to initiate me.  And as promised, I bent forward over a table for him.  His big cock felt wonderful inside me, it had been a long time.  This time I had worn a short skirt, which was pulled up around my waist, and a loose top, which Bill soon had up under my armpits.  At first he cupped my tits with both hands, but another cock was presented for me to suck so Bill held onto my hips so that I could reach forward more.

I took the second cock in one hand, intending to suck it, but was put off by the smell so I wanked him off instead.  He came on my tits.  Bill grunted and came.  All too quick.  I had intended to fuck just one that night, but got a bit carried away.  Several of them fucked me, all from behind.

I was slightly surprised when another woman, Sally, availed herself of my free swinging tits.  I hadn't expected to be fondled by a female.

So that was my introduction to dogging.  I had gone longing for a cock and ended up having several.  I had enjoyed it.  It had been risky, sleazy and delicious.  But it lacked the warmth, the closeness, that I had felt in the early years with my now ex, husband.  Perhaps I really needed a partner after all.  Preferably one who was also into group sex.  And with a cunt-stretcher cock.
