Things had been going quite nicely around the house for a while now. My sister Phoebe had moved in with my husband and me, and she had taken on her role as Paul's second mistress beautifully.
When this arrangement began, Phoebe and I would constantly tease Paul, and we allowed him many opportunities for relief. For the first couple of months, he got released from his belt multiple times per week, Phoebe and I would alternate taking care of him, and sometimes even do it together. (This was clearly his favorite; he believed that this occurred when he had been especially good, or when we both needed him so badly. The truth was actually the opposite. Those sessions usually occurred when Phoebe and I were in a hurry or not in the mood, as he never lasted long.)
Giving him this much satisfaction so often was not part of our original plan, but we had rethought our goals and had decided that this was a way to get him permanently addicted to us, just in case he wasn't already.
Eventually, we slowly started extending the time between his releases. A day or so at first, then two; soon, without Paul even noticing we had him to a week or so between releases. We always rotated the days on which it occurred, so that unless he consciously thought about he wouldn't notice. It wasn't like it was every Saturday (which he would have picked up on); it was a Tuesday here, Thursday, there, then the next Wednesday, etc.
Oftentimes when it had been an exceptionally long while, eight to twelve, maybe even fifteen days, we would come up with a reason to "reward" him. We called them "Special Treat Days." This was kind of an inside joke. He thought that it meant he was getting a special treat, when, in reality, Phoebe and I were.
We would get dressed up, remove his chastity belt and take him out with us. One of us would drive while the other sat with him in the back seat, teasing him throughout the drive, keeping him hot and bothered, but never allowing him to cum. We would allow him to rub and worship our feet while flashing him a bit.
Most of the time our destination was a nearby shopping mall. We would go to stores and try on sexy outfits for him, always starting at the shoe stores. We would allow him to place the shoes on our feet as we tried them on, then we would model them for him, and, when the store employees weren't paying attention, stroke him with them and let him kiss them. We would stroke his balls, cock, chest, face and anything else we could touch. Not surprisingly, he always agreed to make any purchases that we wanted.
It was the same pattern in the clothing stores. Usually though, after Phoebe and I had decide which items we wanted, one of us would lure him into the dressing room and really turn up the teasing. Once, I stripped completely naked and had him lick my feet and legs completely.
Another time, Phoebe had him strip while she did as well, and they began to have sex. Almost as soon as he entered her though, Phoebe faked that she thought that she had heard something and made him stop; then she got dressed, instructed him to as well, and they left the dressing room.
The real purpose of these long private teases was to distract Paul from the register area while the other one of us was making the purchases. Rather than simply paying for those items, we would instruct the clerk to open store charge accounts for us, using Paul's information, of course, but listing ourselves as authorized users. We would complete the necessary paperwork while Paul was distracted, then when he finally made it to the register, he would be so sexually wound up that he would want to just sign the papers and get out of there. He was never much of a shopper, and I'd have been willing to bet that he never even realized that he was opening all of these accounts. These accounts allowed us to come back whenever we wanted, without having to deal with Paul and get whatever we wanted.
