After the Saturday that Pat had tied me up and left me to Cathy, I now owed her seven days as her slave. She used several of them up during the course of the next two weeks and had only four left. Mostly she just had me eat her pussy and lick her ass in the morning before going to work and in the evening when we got home from the gym. If I got off at all it was because she told me to jerk off while she watched. My cock was starting to ache for a warm pussy or mouth to cum in. Pat had been talking with Cathy almost every day and they had been cooking up a plan that I was about to find out about.
About mid-morning on Saturday Pat said we needed to go shopping. First she took me into the bedroom and made me take off my shorts and underwear and put just my jean shorts back on. I often had her wear short skirts with no panties and I figured she was returning the favor. I didn't know what we were going shopping for but we headed to Walmart. On the way Pat started rubbing my cock while I was driving. I got hard and hot pretty quick. She rubbed and stroked my cock thru my shorts just enough to keep me hot while I was driving. Once we had found a parking space she told me to go into the store and buy a large leather dog collar and leash. I was about to get out of the truck when she said to wait and that she wasn't finished. I thought she had something else that I was supposed to buy but instead she started to rub my cock again, this time really fast. Before I knew it she had made me cum in my pants. She smiled at me and said "now go buy that collar and leash, and don't be stopping in the restroom." I got out with a load of cum in my pants and a half hard dick and headed into the store. Luckily I found the pet department and collar and leash quickly before I soaked thru my shorts. When I got back to the truck Pat checked the size of the collar around my neck. It fit to her satisfaction and we drove home.
Our son had an out of town soccer game that afternoon and Pat drove him over to the school to catch the bus. While she was gone she had me shower and shave. I had already shaved that morning but she told me to shave again anyway. When Pat got home I was out of the shower and dressed again. Pat told me we were going out in her car and she was driving. Once I was in the car Pat told me to put on a blindfold she had brought. We started driving and I tried to keep up with the turns and figure out where we were going but it was hopeless. After the first couple of turns I was totally lost. After what seemed like 20 minutes we pulled into a long paved driveway. We parked and Pat told me to strip in the car. Once I was completely naked, she put the dog collar on my neck. Pat got out and came to the passenger side, opened the door and attached the leash to my collar. She led me, bare assed naked, up the drive and walk, to the front door of the house, where she rang the doorbell. Someone opened the door, and without a word I was led inside.
