For this I will call her Sandy. She was a tall slim blond in her early twenties with a fantastic figure that I had drooled over on the numerous times ... had seen her in a bikini. I knew exactly what I wanted for my wife who was of a similar stature to Sandy but much shorter. That was a "Janet Reger" lingerie set that was well out of my price range on a normal day, but tonight it was going to be mine. I pointed the set out to Sandy that had caught my eye. This included a bra, thong, suspender. "What?" Strip! Unbutton your shirt, remove your tie and so on. Until everything is off." This is crazy!"I hadn't noticed there was someone standing behind me but I felt another needle jammed, this time into my butt."What the hell?" I shouted. My eyes glistened and I started to cry, "What are you doing? I have a plane to catch."The woman shrieked, "You needn't worry! You'll make that plane." We know your expertise," she said, "We are not asking you for your help. We are telling you that you will. After a while we got bored and decided to head back to John's place.I went and got the car. I pulled up to the curb to pick John and Carol up. Carol said to John she wanted to talk to me for a minute.She pulled me aside and whispered, "Can I ride in the back with John?"I nodded my okay. John opened the back door and climbed in. Carol followed him into the back seat. John looked pleasantly surprised. I started the car and drove towards home. I could hear some whispering from the back seat. . “You forgot to say mistress! Say ‘yes mistress’ now!” “Yes mistress!” I half whispered, half groaned. “There you see you can be a good boy can’t you, now up on your hands and knees for me, come on chop chop!” I struggled into position, aware that I was in no fit state to argue, stunned by her anger and spite. “Keep still!” she warned as she slid first two then three fingers up my still very loose ass.“You know with a bit of practice I could get my whole hand up here” she said almost to herself,.
