Joe and Thelma invited my lady, Mandy, and I to an evening in their hot tub, situated on the terrace of their London garden. Mandy was a bit taken aback when I suggested swimsuits would not be neccessary, but took one anyway. After a welcoming drink we went out to the tub, stripped off (except for Mandy, who hesitated before started to change into her bikini) and were soon enjoying the jacuzzi. Joe mentioned that Carol and Ted were expected; after about an hour Ted arrived, bringing apologies from Carol who had been called for babysitting duties. Prior to Ted's arrival Joe and I had been gently caressing our ladies, Mandy shedding her top in the process. Ted was soon naked and in the tub, and playing footsie with the ladies. I needed the loo, Joe needed more wine, so the two of us lef the tub and made our way indoors, shrouded in our towels. Before going back outside we discussed how best to have some fun with our ladies, preferably a swap of some sort, but went back outside to find Ted had stolen a march. He was sat between Thelma and Mandy obviously stroking their legs and thighs under the bubbling water; I knew Thelma was always ready for a little mischief, but was surprised (pleasantly!) that my Mandy also seemed to be at ease with Ted's attentions. Joe and I sat on the other side of each others women so I was soon stroking Thelma's other thigh, leaving Joe to give his attention to Mandy. It was soon clear that Ted's hand had moved up and was now playing with Thelma's vagina. Was his right hand doing the same to Mandy? "Oh, thats' lovely...." said Ted, his head thrown back with the sensation; I assumed that Thelma was giving him a hand job, but that theory was scuppered when she lifted her wine glass with her right hand....yes, it was Mandy doing the honours. Joe was playing with Mandy's breasts, and had guided her other hand onto his cock. Mandy seemed to be enjoying this; Ted was whispering something to her, and after a few seconds hoisted himself up onto to rim of the tub, revealing a handsome and very stiff cock; without any further bidding, Mandy moved round to face him, taking his manhood in her mouth. I followed suit and soon had Thelma giving me a lovely BJ...Joe was behind Mandy feeling her bum and love hole; she was getting quite 'warmed up' if I recognised the signs, and started wiggling her bum in invitation to recieve Joe's cock. He was soon in, and she had her first spit-roast. It was'nt long before Joe came and pulled out, but Ted was still going strong: Seeing his chance, he.slid down off the sill, placed Mandy against it, and quickly entered her from behind.....his visit was relatively short, and with a few short grunts he unloaded his man-juice inside her. I apologised to Thelma later, but being driven by something best described as lust, I disengaged myself from her and positioned myself behind my Mandy with the best erection I had had for ages; the sheer pleasure of entering her brought me on unusually quickly and after a few robust strokes I shot my semen inside her, to join that of the other two. She turned round, sank back into the tub and gave me the most passionate kiss......I settled down beside her, my hand exploring her very sticky cunt...small strands of spunk were slowly floating to the surface, causing some amusement. Ted in the meantime was struggling to regain a hard-on, encouraged by Thelma. It took time, but he eventually made his way into her welcoming fanny, lasting much longer this time. His duty done, he joined the rest of us in a last glass of wine before we all had kisses and cuddles before getting out and returning to the house to dry and dress. The journey home was a revelation; far from being disgusted/angry/ashamed, Mandy freely admitted she quite enjoyed the whole thing. We never did find the bottom piece of her bikini..........
