We'd been to the swingers club in Aston twice before, once to watch, the second time we'd played together and let two men watch. On this third occasion we'd been out and got quite drunk and gone on the spur of the moment. The drink had removed any inhibitions and we immediately stripped off and began playing together but Kay felt quite uncomfortable in the open room so we found a smaller room. I thought that would be it, just the two of us again but still it was a turn on just being there. I was licking Kay out and rubbing her big black tits when a man appeared at the entrance and asked "is this a private party or can I join in?" To my amazement Kay said come in. I moved up her body and whispered are you sure? "No" she smiled nervously. He was next to Kay in seconds his naked body lay alongside hers, our whiteness contrasting her black. "Is it ok to touch?" He asked. She looked from me to him and nodded. He enjoyed the feel of her tits and tummy then we sucked a tit each taking turns to stimulate her clit. She came against his finger. Her face flushed confused and excited. I asked if she wanted to touch him. He reassured her there was no pressure. She said she didn't know and asked me what I wanted her to do. "I'd like you to suck him". Flushed, breathing quickly, she nodded her head. He rapidly got to his knees next to her and she propped herself on one elbow taking his cock in her hand and guiding it into her mouth. She didn't appear apprehensive and sucked him in the whore like manner that she's sucked me many times before. I resumed dipping my tongue in her while he helped out by flicking her bean with his finger. This tipped her over the edge and she came very noisily causing his cock to slip from her mouth. As she lay there panting I knelt up on the other side of her and began wanking. He did the same. A smiling Kay reached out both hands and started tickling our balls. This was too much for me and I emptied my balls all over her tits and he soon followed suit moaning like a porn star and spraying his seed all over her 38fs and belly and then rubbing the combined spunk into her skin and pussy. We got back our breath, he kissed Kay politely on the lips, shook my hand and left.
