Several weeks had passed since Alex had convinced Karen to spice up their sex life with some light denial play. Since then, things had fallen back into their usual rut. They had sex a couple times, and it was better than it had been, but things were clearly regressing. Karen might tease Alex before letting him cum, but he always came and things were generally enjoyable, if not as intense as they were. Alex went back to looking at porn three or four times a week and his interest in Karen waned.
One night, as things things were heating up, Karen suddenly stopped. "Close your eyes," she said playfully, "I want to try something." Alex, already naked and ready to go, sighed "sure" as Karen put a shirt over his eyes and hopped off the bed. Alex could hear her go over to the closet and start rummaging around in their "box of things," as they called it.
The jolt of cold steel on his cock woke Alex from his stupor. It was so unexpected that it took Alex a moment to realize what it was. About a year ago, they had ordered a novelty cock cage off eBay. It was ill-fitting and uncomfortable, but it made for a fun few nights before they forgot about it, like all their other sex toys.
"Shhh. Last time was fun, don't you remember? Let's do it again." Karen whispered as she closed the ring around his balls. The cold metal softened Alex's cock just enough to get the cage on. It didn't do much to constrain his erections, but was more than enough to prevent him from getting off.
Karen slipped the lock onto the cage and closed it with a small click. "There now," she said grabbing his constrained package, "let's have some fun." She held onto his confined junk as she moved up to kiss him. As her tongue probed his mouth, she kneaded his balls, making Alex moan slightly. Her other hand went to one of his very sensitive nipples and started playing with it. It was too much for Alex and he started gyrating his hips, trying to hump her hand.
Karen pulled back and looked at him with a mocking expression. "Hey now, I thought this was about my pleasure." She pinched his nipple hard and laid down on the bed, spreading her legs and looking at him expectantly.
Alex wasted no time kissing her and exploring her body with his hands. He caressed her thighs and legs, taking care to avoid her breasts or pussy. He wanted to take his time getting her warmed up. Karen could feel the the cage on her leg as Alex uselessly humped away. The feeling of the cool metal, and knowing what it meant was getting her wetter and wetter.
Karen put a hand on Alex's head and pushed down gently. Alex took the hint and started kissing his way down body. First her neck, and then all around her tits. He took his time, gently encircling them with kisses before taking turns sucking on one nipple while massaging the other breast.
Karen was getting more and more turned on and started growing impatient. She grabbed a handful of his hair and forced him further down. Karen kept hold of his hair as he started to go down on her, using it to guide him.
As Alex went down on Karen, she pulled his hair harder, which made his cock strain against the cage more. It wasn't the pain so much as Karen's taking control, but a little bit of pain was nice. It wasn't too long before he was gyrating his own hips, unsubtly humping the bed and moaning into Karen's pussy.
Karen came loudly all over Alex's face. Alex backed off and gently kissed around her smooth mound as she came. She ran her fingers through his hair as he brought his face up to hers. She could taste her pussy as they kissed.
The kept kissing as they switched positions and Karen got on top. Her hands roamed over Alex's body, one hand eventually settling on his caged cock. The holes in the side were big enough for her to touch him, and she couldn't help but giggle when he jumped at her touch.
"Sorry, it's just that it gets more sensitive when it's constrained like this," Alex said, blushing. Karen laughed and told him she liked it. She kissed him one last time and sat up next to him. Alex reclined with his hands behind his head and his metal-encased cock standing at attention.
"So what do you want to do about that?" He smirked.
"Whatever the hell I want," was the reply. Karen gave his nipple a quick pinch and laughed when his cock twitched in response. She leaned over to suck on one and bit it gently, listening to his half-moan, half-whimper. They really were very sensitive all the time. It was fun. As she worked on his nipple, his hips started involuntarily humping the air. She wasn't even sure he noticed how much he was squirming.
That wasn't her target though, and went to take the head of the cock cage in her mouth. Alex looked down in anticipation as she slowly engulfed the top of the cage. The memories flooded back of the last time, as Alex realized he couldn't feel a thing. There was some warmth and wetness from her mouth, but nothing else. He watched as his beautiful wife sucked a cock that might as well not be his!
Karen looked up and smirked with the metal cock in her mouth. She kept at it, knowing that Alex couldn't feel a thing. He'd get flashes here and here of her tongue or mouth, but all that did was frustrate him more. Eventually he grabbed her head and tried to fuck her face, but it was all useless.
"Awww, that's right, nothing huh?" She said with a mock pouty face. "Maybe a handjob?" She used her hand to work the cage, and it was a bit better. The cage moved up and down, but it was so poorly made that it started chafing. There was no way Alex could cum like this. Karen saw his discomfort and laughed cruelly.
"What about a fuck? Hmm?" Karen said as she straddled his hips. The cage was a bit bigger than his cock, but she was so wet that she was able to work it partway into her pussy. Alex was still humping futilely, hoping to get something out of it. He cock was starting to ache and he was getting desperate. Karen leaned down and whispered in his ear, letting the cage slip out of her in the process.
"You want to cum?" Alex nodded and kept humping the air where her pussy used to be. "Well, I'm having fun and don't want it to end. What are you going to do about that?"
"I'll make you cum again afterwards. Please."
"I don't know, as soon as you cum, you lose interest. We both know that." She nibbled his ear and started grinding her pussy against his cage. "I need to know you'll still want to keep going. What about tomorrow? Or the day after?"
"I will, I will. I promise. Just let me cum."
"I think we both know that's not good enough." She was still rubbing his cock, picking up speed slowly. "Why don't we try you not cumming again? Last time worked. I bet you could go a week without this time." Her breath was hot in his ear.
