'This is the most humiliating moment of my life,'
Isabelle thought as she sat in the passenger seat with her head in her hands. Public exposure; she couldn't believe herself.
"So let me get this straight, Isabelle," Nathan said, not looking away from the road. He never called her Mom when he was angry with her. "You were... touching yourself. In the middle of a parking lot."
Taking a deep breath and pushing past the embarrassment, she explained, "In my car, not just out in the open. But that's basically right."
She glanced at Nathan for just a moment. Being his guardian for years, she could tell he was also embarrassed about the topic. He tightened his grip on the steering wheel as he wrestled for control of himself,
"I'm... not completely oblivious to your... urges. Oh, forget it. You're the horniest person I know. Frankly, relying solely on law enforcement to curb your lust-driven behavior is not a great arrangement. You're clearly struggling to manage your libido on your own. Fortunately, if you're willing to try, there are ways for you to stay accountable."
Confused, Isabelle asked, "What, like a support group? I'm not a sex addict. I haven't been with anyone in-"
"Not a support group Mom," he interrupted. "It's something to physically remind you to keep your mind off of masturbation. It's a chastity belt."
She was shocked and unable to process what he just said. Her thoughts ran unbidden for a moment.
'Was he planning on locking me in some medieval iron belt to keep me away from my pussy? How would that even work? He was so nervous just a second ago, but now he looks totally calm. I'll just keep quiet and let him explain a little more before I speak.'
"It's not some weird Dark Age thing," he said as if answering without me having to voice the question. "There are manufacturers who design belts that are sanitary, fit well, and can be secured with a lock and key. The idea is that you would be wearing the belt, and I'd be keeping the key. Each time you get the urge to do something you shouldn't, the belt will prevent you."
She asked a few questions about how she'd be able to pee, if it would show under her clothes, and if she'd have to wear it all the time. He answered as much as he could, oddly free of the tension he held just a moment ago. He said that most of her concerns would be explained when they wrote up a contract. The odd family sat in silence for the rest of the drive. When he finally pulled into the garage, she made her decision.
He brought his laptop to the dining room table and pulled up the website he would be ordering the belt from. When Isabelle saw it, she became a little calmer. It wasn't some brutalist prison. It was very low-profile and thin. Nathan explained that each one is custom-made, so it can be comfortable and secure. He told her what measurements he needed to place the order. When Isabelle asked to take the laptop and enter it all by herself, he gave her a very stern look before handing her a pen and a slip of paper.
Giving him that kind of intimate information about her figure felt a little strange to Isabelle, but she would have to get used to it. At least she had nothing to be ashamed of in terms of her waist and hips. In fact, she half-expected Nathan to question if those numbers were right. He took the slip of paper and entered the measurements into the order form without comment. She forgot he was a man and had no clue what he was looking at.
Nathan insisted that they draw up an agreement that clearly spelled what would happen. He pulled up a basic chastity contract after ordering the belt. By default, it was full of BDSM elements, making reference to sexual service and harsh punishments. After a fairly short discussion and serious pruning of the more extreme clauses, they printed out the contract and signed it.
