My girlfriend and I became interested in dogging after watching video clips on the internet. We looked up some local locations and headed down in the car one night after geting stoned. I pulled up in the layby which was behind some trees away from the road, noticing several cars parked up ahead in the dark. She started to wank me off as we sat and waited to see what, if anything, would happen. After about ten minutes I told her to get her tits out and put the interior light on. Soon enough someone appeared at her window, jerking himself off through his pocket. My girlfriend was a little taken aback but continued to wank me off. I told her to wind the window down, she did and the guy leant though and started fondling her tits, she was surprised and excited at the same time. She wound the window down fully and spread her legs to show her naked shaved cunt, and masterbated. The guy kept fondling her tits until eventually he leaned in and started fingering her cunt, she was breathing heavily by this point. I told her to open the door so that he could lick her out, which she did without hesitation. I had a raging hardon whilst watching some random stranger on his knees licking my girlfriends cunt as she sighed. A few others had appeared by this point, standing round him. They began to take it in turns to lick and finger her. I pushed her head forward and told her to suck a cock, a guy immediately stood next to the one licking her and got his cock out, I felt a wave of sexual excitement hit me as I watched her take this strangers cock in her mouth and start sucking him off. OIne after another they came and stood until their turn came. She let them choose whether they wanted to come on her tits, face or in her mouth, the dirty bitch! She had cum on her face, mouth and tits. After I had been wanking and watching I suggested that she might like to get out and we walked over to a picnic table which she bent over, the guys queued up to fuck her, one pulled her hair and called her a whore which turned her on even more, knowing that I was right there watching. After seven men had stuck their cocks in my girlfriends mouth and pussy, she ended up on her knees being spit roasted, again the guys took it in turns to fuck and be sucked. I couldn't believe I had let my lovely girlfriend be used and abused like this, but we loved it. She was gangbanged by nine men, each fucking her, being sucked off and coming on or into her, she was just used like the filthiest whore, I took great delight in watching and wanking as each man wanked into her mouth, or onto her face or on her exposed tits, some had come while being blown by her pretty mouth and had spunked down her throat which she swallowed. Finally it was my turn, I made her lick my balls as I wanked then held her head while I came explosively on her face. Sine then she has been the subjet of several gangbangs where she gets used like a sex doll, she has been dogging on her own once or twice and given a lesbian show before being gangbanged and coming home to describe it to me.
