The door opened, as it did my heart was in my mouth what the fuck do I do now, quickly I jumped up and sat back down on the settee, I tried in vain to cover myself up but the raging hard on although diminishing through fear was still evident , all I could do was put my hand over it as my trousers were barely up. She was also sat on the settee next to me but said nothing, I was confused as she didn’t seem to concerned about what was happening, I was wondering how do I fight to defend myself in this dishevelled state. I needn’t have worried. He walked in I must have looked ashen, he said you alright, yes I replied sheepishly. Good night he said I’m knackered now, yeah it was good I replied. She got up and said well I’m off to bed now. Goodnight I said. He said well you coming to bed, what do you mean I replied, well you have half had her you better come up and finish what you started he said, it’s up to you but if you want come up, at that he went upstairs. I sat confused for what seemed like minutes but was probably a second and followed them up. When I entered the bedroom he was just getting in bed and she was in the loo, I undressed and got in bed with him. I should point out at this stage that there was no intimation of any Bi activity and none was expected or wanted. After a few minutes she entered the room , she was naked and in the half light looked gorgeous her pendulous boobs hanging down beautifully and the shape of her body looked fantastic. She got in bed next to me and not in the middle as I had expected. She kissed me passionately our tongues entwined. We kissed for a time and I knew that I had to have those tits in my mouth again, her nipples were erect and eager to be spoilt. I nuzzled and sucked like a child on those boobs they were gorgeous. As I did so her hand found my hard cock and she began stroking and wanking it. I was so turned on I almost forgot that her husband was only inches away from me, my only thought was don’t cum yet for fuck sake I was so turned on. She wanked me for a while and she said come up her I want to suck that cock, didn’t need asking twice and moved up the bed so she could suck me she licked around the end teasing the end with her tongue, it was glorious. I said don’t you want to let the old man join in, no she said that’s not what we want. She sucked me for some time while I fingered her pussy which was sopping wet and eager to be fucked. I pulled out of her mouth and went down between her legs and eagerly lapped sucked and licked her pussy which was delicious and smelt eager to be fucked. Fuck me she said, I moved up and entered her god it felt good, it was rampant fucking not love making that wasn’t my job that was for her husband we moaned and groaned and I fucked her hard and fast I needed no encouragement but she said fuck me cum in me. I knew I was close to cumming and sped up even faster my balls slapping loudly against her arse, with a fuck yes I exploded inside her as she cried out fuck yes and came her wetness and my cum mingling inside her, I collapsed on top of her both of us breathing heavily. I then became aware of her husband wanking next to me , as my cock softened and fell from her I moved off her and rolled to the side leaving her in the middle, as soon as I had he entered his wife and started fucking her, there was no noise and shortly after he obviously came and rolled off. There was very little said at this stage I was fairly naive and didn’t know the etiquette of what had taken place, I said well I’d better go now it’s getting late. Ok they said. I was a little embarrassed now kissed her on the lips and left. The following day I met him at work very little was said except later in the day he said that was good last night but keep it to yourself. I have until now. We did have another meet together a few years later when I wasn’t quite so green but that’s for another day. Hope you enjoyed the story.
