I stood there in stunned silence, we were standing in the middle of her patio, in the early evening half light, me now pulling on a pair of Michelle�...s still warm panties. She took the pair that until 30 seconds earlier I had been wearing and stepped into them. She swiftly pulled them up to the tops of her now very visibly thighs and to my delight I saw the very neatly trimmed triangle of her pussy. As the light caught the soft curls of her velvety soft mound, I could make out the folds of her. We were both exhausted from a bondage session - I was on the bottom this time - and we were about to fall asleep in each other’s arms. “Mark, are you still awake?” she said to me, stroking her blond hair.“What’s up, Diana?” I asked.“Do you know how you used to say how exciting it would be to have someone else join us?”“Well, yeah.”“I was thinking….maybe we should get somebody.”I was shocked. She was an animal in bed, but I seriously didn’t expect that. And most of our friends were completely. When her husband returned home he was a bit shocked seeing his old friend sitting in his home and was only to welcome in agreeing with his wife that Bazza could stay, Steve took Bazza up to the spare room as Helen gave him bed sheets. That night they all sat down stairs having a drink and catching up on things. The next day Bazza woke up and headed downstairs only in a tight pair of boxer shorts, his bulge was showing pretty much, Bazza has always had a good cock size and was only to proud to. Even so, my cock had a lazy lob on. "Oh yes, have we go some joys for you? You're going to find you have talents you haven't even heard about!" I wondered what he meant.Out of a bag he produce a steel shackle, which he fastened tightly around my balls and cock. It was cold, and heavy, and I'm embarrassed to say, rather erotic. The tether that had been clipped to my handcuffs was now clipped to the shackle, and my wrists re-cuffed behind my back.The second guy took some alligator clamps out of.
