I didn’t mind. I used to come back home after every 7-10 days and every time found her at the peak of her sexiness. One night while we were approach...ing orgasms I could hear her murmuring softly the name of one of her old crush (she told me of that man after marriage who was quite elder to her and was her neighbor). I understood she was fantasizing that man and the same thought gave me a strong kick. Those days I was unaware of ‘swapping/swinging/cuckolding’. But the simple thought of my wife. Dennis walked from the back and introduced me to the clerk, Keith. Keith was about 30, short (about 5'5") with brown hair, a bit of a gut and a mustache. Dennis is a couple of years older with black hair, a dark complexion and fit. Dennis led me around the counter and opened the door to an office in the back. The first thing I noticed was the large one way mirror looking out over the counter and store. The second was the monitors behind the counter showing the halls in the back. I knew then. Without showing a lot of skin it was a hell of a sexy dress. I didn't think that look was good for Sally but I had to give in when we found one like it in her size. For Sally it was three high dollar skirt and blouse outfits, all the skirts were really cut to show off her ass. The sales girl grasped what I was looking for and brought out a designer blouse and had Sally try it on, and then the girl showed us how the sleeves were cut to constantly give small glimpses of her bra. That plus the. My cock was iron hard now as I stood and watched my wife relinquish herself to this stranger, reveling as their naked bodies hungrily ground against each other clad only in their stiletto heels. Pinned to her back and in total darkness, Amy writhed beneath her as her partner crawled higher to let Amy's outstretched tongue lap across the pebble hard nipple that hung above it. Panting heavily now, I knew what my wife wanted. Her arousal peaking, she craved more. As our partner eased herself off.
