Last Saturday we ended up going for a drink after work as usual but this time decided to leave Maidstone where we live and get a cab to Rochester. It was still early but we had a few drinks in a chain pub and my wife even got chatted up by a young fit guy while i was upstairs in the loo. She knows i would love to see her with another guy but till now has always refused to get involved any further than just chatting. They were getting on well so i left them alone as long as possible but i couldnt hold on forever so eventually i wandered over. Sadly he quickly said see you later and wandered off. Bugger. She knew what i was thinking and just laughed,better luck next time,she said. We had been here before. After a while we decided to get another cab back to Maidstone. In the back of the cab i realised she had drunk more than she usually does. She was louder and giggly. I kissed her and it turned in to a snog. I took a chance and ran my hand up her dress,lifting it as i did so. No protest. The driver was a stocky young guy and said nothing. Normally she wouldnt let me get away with this so it was all new to me. My hand found her panties and i gently rubbed at them as i felt her hand brush the bulge in my jeans. I placed her hand on my bulge and she squeezed. By now we were not far from home. I stopped kissing her and leaning forward i said to the cab driver to take us to a car park i know near to where we live. He grinned and said no problem. I thought we were going home? She said. I cant wait,i said. She looked confused for a second then i think went to protest but i kissed her again and held her close. There was more fumbling. A couple of minutes later we were in the car park. I asked the driver to park over in the far corner. As he was doing this i slipped my fingers inside her panties then inside her. She was panting and looked a little taken aback,almost nervous. She was soaking wet though and my fingers slid inside easily. She groaned and clearly liked it but still she said No,lets go home,not here. I carried on slowly pumping two fingers in and out of her. She closed her eyes,lay back and parted her thighs a little further. I persisted and she seemed to relax,almost forgetting the driver was there. It only took a minute or so and i knew she was about to cum. She bucked slightly,gasped and came with my fingers still inside her. The driver was leaning between the seats watching her. I started to unfasten my jeans and she pulled me down on to her. Soon i had the tip of my cock positioned at her wet pussy lips and i slid straight inside. She groaned loudly as i started to fuck her. I wasnt going to last long. The presence of another guy watching us,watching her being fucked was too much. I felt myself start to cum. Dont stop she kept saying,dont stop. But it was too late. I came inside her. She said no,no NO and with my cock still inside her she started playing with her clit. I had to withdraw and as i did she slipped two fingers up inside herself and pumped them slowly in and out. She was looking at me and looking at the driver. Looking from one to the other as she frigged herself. The next thing i knew he had exited the car and opened the door behind me. I got out,pants at half mast,almost in a daze and he took my place. By now her hand was a blur on her pussy. She hadnt stopped. Her eyes were closed and she was almost ready to cum again. Her fingers were soaked with her juices and my cum. You could see everything,aided by the fact she is shaved. He already had his trousers half down along with his shorts when he got in the back with her. I watched him move between her parted thighs and wondered if she would call out for me or tell him to get lost but seconds later he groaned and she called out loudly as he pushed his cock in to her. In to my wife. I was panicking a bit,partly in case we were all discovered and partly in case she didnt want this. My cock however was back to rigid again as i watched him fuck her. She was moaning loudly and he was fucking her really hard. Slamming in to her. It was like he was using her but she was using him too. He had pulled the front of her dress open and managed to free one breast. I am pretty sure she came once but maybe it was twice. Looking over them i watched them snogging as he fucked her. Her moans were muffled. I have no idea how long this went on for but he started to groan and she was making little whining noises then he thrust once,twice,three times hard in to her and filled her with his cum. Looking over his shoulder i saw her looking down at his cock embedded in her. She was smiling and panting,transfixed by the sight of another mans cock deep inside her. They shared a quick kiss. He kissed her then she kissed him,he exited the back of the car and she drew her dress around herself. I glanced at his flacid cock as he dressed himself and it was a good size,probably similar girth to mine but i have to admit clearly longer. After a moment or two he drove us silently the mile or so to our house. It felt weird paying him but he took it as though nothing had happened. He even gave her a peck on the cheek. With a grin he drove off and we went in. She was quiet and a bit emotional. I reassured her and after kissing and cuddling for a while i told her it was the horniest thing i had ever seen. I fucked her on our sofa there and then. She was soaking as i added yet more cum inside her. To be fair we havent stopped fucking since. It has given our sex life a massive boost and although it hasnt been discussed or even mentioned i am hoping for further performances.
