Based on a true story: mine. To avoid further damaging the skin on my penis I can't just rub it any more. If I'm going to beat off without causing damage, I have to use a lube. Since I can't get naked and use a lube in the middle of the afternoon without someone noticing, I don't beat off. That means I still look at porn, but I no longer masturbate to porn. Ever. The change has been good for my relationship with my wife. The change has also been good for our sex life, which is what gave me the kernel of this story. The details, however, are my fantasy of how it might be.
Part 1: Beauty Treatment
"Your doctor warned you about this, more than once. I've reminded you about this. More than once. But you're too easily caught up in the moment, you have no strength."
Andy's angry wife Barbara paused, glaring. "I get some use out of your cock, too. Not as much as you, apparently, but I get some use out of it. Right now I can't use it, can I? Now with the skin on it looking like that."
She paused. "Pretty selfish to take sex away from by having too much on your own, isn't it? Now you've gone so far you can't even use it yourself. You can't be trusted to keep your cock ready for us to share, and I'm worried you'll just keep in beating off and end up making is unusable for both of us. So I am going to take your uses away from you. From now on your cock is my toy, not yours. And it's going to stay that way until I decide you can be trusted with it."
She pulled out of a bag the chastity cage they had played with several months before. She pointed to the open padlock. "This time you already don't know where the key is.
"You know, when you raised the idea of chastity, I knew you were masturbating too much and I thought you were making a sincere effort to make a change. I was disappointed to discover it was just another kink that kept you masturbating."
She set the cage back down. "Before we put this on we have to see to treating you for this condition."
She produced a tube of lotion. "If you weren't constantly rubbing yourself, your skin wouldn't be so badly worn. Hold still."
She applied a generous amount of lotion to the palm of her hand, capped the tube, rubbed her hands together and began stroking Andy's cock to smooth the lotion into the skin. He wasn't hard when she was scolding, but he rapidly got hard under the sensuous massage. Her lubricated hands even circled his balls, gently massaging to moisturize all the skin of his genitals.
The feeling was overwhelming. Andy's hips were bucking with an involuntary response to her sensuous ministrations.
"Are you getting close?"
Andy nodded, unable to speak. Barbara stopped massaging. Andy gasped, his hips bucking even more in search of her sweet hands.
"Here's the deal," Barbara said. "You will be caged unless I want to use your cock. That will keep you from masturbating so often, and no masturbating will keep you from rubbing your cock raw. Save it for me.
"Don't worry, I plan on having your cock out to play with quite often. And, of course, I'll have you out of the cage every night for your beauty treatment, like this, but that doesn't count as my having fun with your healing cock, it's just me doing maintenance on my property."
Andy finally found his voice. "How long will this go on?"
"I've thought about how I'll know I don't need to keep you caged any more. When you can last twenty minutes with me stroking you like this, without moving your hips, just sitting still and letting me stroke in this lotion, then you can start having your cage off part of the time." She smiled encouragingly. "Just twenty minutes, that's all you have to last. You can do that if you apply some strength of will and focus on the long term goal."
She added some lotion to her hand from the tube and returned her attention to slowly stroking his erection. "Instead of instant gratification.
"I want to help you accomplish this goal. It is important for me that you succeed. I suspect right now it's even more important to me than to you, but in time it will be more important to you than to me."
She continued to stroke him slowly while he gave all of his mental energy into holding still. His breathing was ragged as he strained to hold off, strained to control his hips that seemed to have a will unrelated to him, wanting to hump his cock into her hand.
After a few minutes more she asked softly, "You're not going to make twenty minutes tonight, are you?" However, she continued stroking.
Gritting his teeth, Andy made a sharp snap of his head to the left, then to the right. He immediately felt her hands stop stroking his straining cock and took a deep breath, trying to calm down.
"I didn't expect you to pass this test the first night," Barbara said. "Are you ready to be caged now?"
He looked at her, incredulous.
"Oh, I know what you're thinking," Barbara told him. "Get you this close then lock you up? Am I that heartless?" She chuckled softly. "I fully expect you to conclude I am heartless before you achieve your goal. Your beauty treatment every night is to restore your skin, not to get you off. If you feel like you're being punished, it's because I'm punishing you while you heal, to teach you a lesson.
"I'll give you a soft start. Just tonight, would you like me to finish you off with a beauty treatment hand job?"
He just looked at her, uncertain how to answer, and in response her voice took on a harder edge. "You won't find me making an offer like that very often."
He met her eyes. He understood the answer she really wanted, and decided to give it. "No, dear, I'd like you to stop now. I think that's better for me."
He said it intending she would believe he was taking her seriously, and maybe ease up on her plan. But her hand resumed stroking, slowly, sensuously but with a firmer grip so he was really feeling the strokes. "Tell me to stop."
