I lay back on my bed luxuriating in the sensation of Mary slowly sucking my cock. I needed a few minutes to recover after our first fuck before I had her again.I'm no porn star, just an ordinary bloke so I can't keep it up for an hour an come gallons. I need a bit of time. Mary didn't seem to be all that worried. I was playing with her clit as my spunk slowly seeped out of her and she seemed to rather like it. I managed to get hard again. Time for round two. I asked Mary what her favorite position was. She said that Simon always had her on her back so she didn't know. Good. I could have a bit of fun here I thought. We spent the next hour or so experimenting with me trying to remember every which way to fuck a girl, getting her into position and sliding into her. Mary was a very willing student. She loved doggy, and cowgirl but her most for-filling was when I stood her up, bent her over the end of the bed and had her standing up groping her very ample tits at the same time. I think what got her going was she was able to watch it all in the full length bedroom mirror and could see my cock moving in and out of her cunt..
I asked her how she felt now that she had been unfaithful to her husband. She said she hadn't been as both her and Simon had agreed to do it, and after all, Simon was even now with Kate, and goodness knows what they were up to right now. She said she was looking forward to having Simon when she got home to see what he had learned from Kate. I asked her if she would like to swap again. She was instantly the shy Mary again, but she nodded slowly, but said Simon would have to agree. That would be a yes then as I have not yet met a red blooded male who would say no to Kate.
We settled down to a gentle sex session. Each of us sucking and exploring each other's bodies. From time to time I would fuck her a little more. I can't normally come more than twice, sometimes 3, but beyond that I can get an erection, but I can't come any more. That wasn't important to Mary. She seemed to be very sexually satisfied and just went with the flow.
About 11pm our phone rang. It was Kate. How were we doing. (I had her riding me cowgirl at the time). We were fine, and everything had gone well. Kate said that Simon was asleep and it was time to come home so she could run Mary back to her own husband. I asked her how were things at her end? She giggled and said her end was quite sore, and she would tell be everything when we got to bed.
Mary got off me and started to look for her clothes. I told her to leave off her underwear and just put on her skirt and blouse and shoes. I assured her that Simon would be more aroused by that when she went to him like that. Once dressed we went downstairs and had to wait 10 minutes before Kate arrived home. Not to waste time I had her bend over the dining room table , lifted her skirt and fucked her until Kate pulled onto the drive. Mary kissed me "thankyou" and said "see you again soon I hope" then went out to join Kate in the car before they drove off again.
An hour later Kate was home.I had gone to bed to wait for her. She came up the stairs and walked into the bedroom. She had undone her halter neck dress on the way up and it was hanging around her waist. Her tits were covered in red bite marks, so Simon had enjoyed himself by the look of it. "Look at the marks on my boobs" she said lifting them up and jiggling them at me. She stepped out of her dress. There were red marks on her bum and round her pussy. Not only that but you could see where his spunk had dribbled out of her cunt and dried on her thighs over the last hour or two.
We went straight to bed and I pushed her onto her back and pushed my cock into her as she told me about her evening.
She had been at Mary's house about 15 mins before Simon came home. He was a little surprised for although he had agreed that he and Mary could swap, he wan't expecting it to be so soon.. He asked Kate where Mary was, even though he knew the answer. Kate said that she had been with me for about an hour so far, so she expected that Mary was in my bed by now. Kate undid the ties on her halter neck dress and let it drop from her tits as she walked over to him.
Simon sat down and Kate straddled him so he could nuzzle her tits and suck her nipples. Kate lifted her dress up to her waist showing Simon that she had already taken off her thong. He needed a little more invitation though as he was almost as nervous as Mary was with me. Kate told him that it was bed time, took him by the hand and walked him upstairs. She undressed him and pushed him back onto the bed. She took off her dress and shoes then crawled up him and took his cock in her mouth and started to blow him. Over the next few hours she sucked him, sat on his face and fucked him three times. She said by the third time he was loosening up and starting to get a little more adventurous. He would be better next time. "There will be a next time then?" I asked her. "Oh yes " she said. Mary had already spoken to her on the way home. Not this weekend, but the weekend after Mary and I were invited over for drinks and shagging.
Kate had told Mary that we would move things forward a little and have a foursome with all of us in the same bed. Simon would get to see me fuck Mary and Mary would be able to watch Simon fuck Kate for the first time. Who was I to complain? It seemed like a plan.
Before we went to sleep, Kate asked me if I was fucking Mary when she got home to pick her up. I had to admit I was shagging her bent over the dining room table. "I thought so" she giggled to me. "Mary's skirt was tucked into her waistband and I could see her bum when she opened the front door. And by the way " she added" If you are going to kiss her goodnight, put your cock back in your trousers first"
Next time 4 in a bed.
