When David returned home from his mother-in-law's it wasn't like the last time. Mary was waiting for him, but even if she had wanted sex he wasn't up to it. She put him to bed and applied cold packs to his battered organs. She coaxed the whole story out of him, how he came to require this punishment, the instrument she used, etc. Still emotional and 'broken' from his ordeal David just let it all out, every detail, including her "appreciation ritual" and his inability to control his arousal at the scent of Momma Ann. All the time Mary felt her pussy get wetter from more than her period.
It was the perfect lead in she needed. "Dear, if only you had told me all the details of her warning last time! We need a solution for this problem, because it seems clear that you will have to perform this service for her sometime in the future. But I think I may have found it."
"What do you have in mind?"
"Well, my friend Jenny told me about something she saw on the Internet. It's a hard plastic tube that fits over the penis. She called it a chastity device, and it keeps a guy from masturbating or even getting erect. I thought it was strange and a little cruel, but we could get one and put it on you before you go over there. That should keep you from getting hard and having her repeat today's punishment."
"Would it hurt if I tried to get hard in the cage?"
"I don't know, but it couldn't be as bad as this," she said indicating his bruised penis.
"I guess that's true," David said half-heartedly. "OK let's get it."
That was the answer Mary had hoped for, in fact, the device was already on its way. While they were waiting for it to arrive Mary excitedly shared with David all of the information she got from Jenny about how it worked for her and her boyfriend. David had to admit that the talk of bigger and better orgasms after a period of denial did sound appealing, and there was no mistaking the excited arousal in Mary's voice as she talked about it. His mind was still focused on the idea of chastity as some sort of super foreplay, and less on what Mary was actually saying. She was using words like "symbol", "trust", "control", and "sacrifice"; and she was pairing them with adjectives like "complete" and "deep". He had quit listening to the words themselves and was reacting to her excited emotions and her praiseworthy tone for what he was agreeing to do, so it all sounded good. Mary knew he wasn't paying that close attention, but it didn't matter, she was being honest with him in general, if not in the specifics, he'd remember that later, even if she had to remind him.
The first week after the device arrived was spent wearing it for short periods, adjusting the spacer/locking pin and cuff ring sizes. David had to get used to doing a few things differently, sitting down to pee was one. But most important, no bending over from the waist; that risked really squeezing his balls painfully.
When the sizing seemed right, his time in the device was lengthened. First just at work, then soon all night and at work, with a break for teasing (but no cumming) in the evening. Evening breaks got shorter, she was tired, or there were activities with the kids that lasted too long into the evening. Sometimes unlocking was missed altogether, but generally he was out for checking, device cleaning and teasing every two or three days.
He had to admit the device had him thinking about sex more often, which he wouldn't have thought possible before. Perhaps more importantly, and more to Mary's purpose, his sex thinking seemed to always involve his wife. If he noticed a pretty girl and casually wondered what she would look like naked, it immediately got him thinking about Mary's naked beauty and wondering if he would at least get some teasing that evening. Every sexual stimulus reminded him of his sexual need and that always led right back to the woman with the power to fulfill those needs. He also had to admit that when Mary allowed him an orgasm, it certainly seemed more powerful than most of the ones he had before. Just the same, it was damn tough at times, and it was about to get tougher.
He was so overwhelmed with the thoughts, feelings and hopes surrounding his chastity that he hadn't thought about the fact that the device was originally intended merely to keep him from getting an erection when showing appreciation to his mother-in-law for her discipline. Again, this was precisely to Mary's purpose.
It was Saturday night, "date night", and David was pretty sure that Mary was going to unlock him and let him have an orgasm. But she'd delayed taking the CB off, and while orally pleasing her for the third time, his cock was bulging out the vent holes in the cage. When Mary recovered from her peak, she reached down and grasped his cock cage and balls; looking him straight in the eyes she said, "I'll unlock you now and let you penetrate me on one condition."
"Anything!" he answered with urgency.
"You cannot cum." She pronounced it simply and slowly.
"But...?"
"Shhh, trust me," she said softly laying her finger over his lips. "I know you're very horny and you want to cum very badly. But it would please me a lot if you waited till next weekend. Will you do that for me?" She used her most seductive look, then added, "You know I always make it worth the wait."
David couldn't deny that. But it was just that he was so looking forward to this orgasm, he had already imagined a huge ejaculation spurting inside Mary's tight, warm pussy. Now he would miss that. She wanted him to enter her without experiencing the "grand finale". He wasn't entirely sure he could hold out if he entered her. What if he agreed but had an "accident" and spilled it all inside her?
