The Last Key In The Jar
Quick thing here to get back in the groove of writing! As always I LOVE getting comments and feedback, so please dont be shy!
You were always unable to take your boyfriend's knot, and you could tell it was eating at him. You decided to take matters into your own hands, and you won't stop until he doesn't have to!
Also not sure if chastity means this goes in extreme instead of adult, lmk if it needs changed.
“You sure you’re ready, babe? This will be your last chance…”
You stared at the single remaining key in the mason jar. It seemed like it had been no time at all since the jar was filled to the brim with nearly identical keys. Nearly, of course, being the important word. You took a deep breath as you lowered the jar from your eyes, bringing your boyfriend into view. The German Shepard towers over you, his eyes brimming with concern, commitment, and desire. You only asked him out because you lost a bet while out with some friends, and were shocked when he said yes. The relationship was perfect. He was kind, sweet, affectionate, funny, and so attractive you still question why he agreed to go out with you. Nothing could have been better until the first night you both had a bit too much to drink. His place was close. Close enough that neither of you were ready to go to bed when you got there. The clothes came off, and the only problem in the relationship came out. He was massive. You knew he would be, but it took almost an hour of fingering and prodding to even get his tip in. Another hour to work your way down the shaft. But the knot? Barring a trip to the hospital, that was not happening. He swears up and down that it doesn’t matter, but you see how he has to stop himself with you. You were getting better, able to take the shaft with only a few minutes of work, but his amber eyes obviously craved more. You could tell he was beating himself up for being unhappy, but who was he to argue with millions of years of evolution?
“Babe? You know I don’t mind the eye-fucking, but if you’re serious then I’d prefer the actual fucking.”
All his self-hatred about needing something it seemed you couldn’t give him came to a head a few months ago. You don’t know how you knew he was going to break up with you, but you knew. Not because he was mad you couldn’t take him all the way, but because he hated himself for being so stuck on one little issue. You racked your brain for a solution, eventually coming to the grandest gesture you felt you could make for him.
“Is this… a jar of keys? I don’t…”
You pulled down your pants, revealing a small metal chastity cage locked securely around your penis.
“I… know you say it doesn’t matter, but… I can see that it does. I see the guilt piling up lately, and this is my solution.”
He studies the jar in his hands with a confused, yet relieved expression.
“The key for this is somewhere in that jar. Every time we have sex and I can’t get the knot in, I want you to throw one of them out.”
The relief on his face quickly vanished.
“Babe I… Look it… does bother me, but… you can’t do this just for me!”
“I’m not doing it for you, I’m doing it for us. I love you, which is why I know that you weren’t going to stay much longer. So that’s your part in all this. I’ll work on it. I’ll get better. And you will stay with me in the meantime. Promise me that.”
He didn’t say anything, just rushed towards me and hugged me as tight as he could. Most days from then on saw a key disappear from the jar. Chastity was a great motivator, but once some time had passed you were horny enough to make attempts you knew were bound to be failures just to feel something. You watched the second to last key disappear the night before he left on a work trip. Of course, you knew that the odds said your key was long gone at that point, but that was the last thing on your mind. The end of this little experiment could very well mean the end of the relationship you were sure you would spend the rest of your life in. You used your PTO on the week and spent almost every spare second making sure that the last key, whether it was yours or not, would not end up in the trash.
“I’m sure, babe.”
He wasted no words once the lovemaking started. He took the jar out of your hands, placing it on the nightstand. Your legs were hoisted into the air, exposing a hole that had spent a week being stretched in every way imaginable. It only took him a single lick to notice the difference.
“Damn, babe. What did you get up to while I was gone?”
You would have responded if you could have before his tongue shot into you and prodded around inside. He was always good at that. Your cage had already started dripping a near constant stream of pre. Two months of denial plus a week of constant training left you in such a state that any stimulation would put you near the edge. Nothing had yet pushed you over it, but the edge was plenty enjoyable in its own right. Before you knew it, his tongue was withdrawn and a cold stream of lube poured down your taint. He lined himself up, and pressed in. For the first time, you felt no pain on the first insertion. His tip slipped right in, your guts begging it to come further.
“Fuuuucck… I’m just sliding right in…”
He didn’t have to tell you that. Inch by inch you felt him invade you easier than ever before. Without the usual struggle of relaxing enough to fit him in at all, you laid back and enjoyed the excitement in the eyes of your boyfriend. The deeper he sank into you, the more you could tell that you weren’t the only one convinced that this would be the night. Finally, he bottomed out at the base of his knot. Normally, you would be nearly on the verge of tears if he worked this fast, but not this time. This time, you felt just as incomplete as he must. You pull his head down for a tender kiss before the room fills with your desperate moans.
“It’s the last one. No holding back, promise?”
“Promise.”
The word wasn’t even fully out of his mouth when he started pulling out. It was his favorite thing he could do with you to pull out to the limit and press back in with even but unyielding pressure. The first few times would usually cause some discomfort, but you felt no discomfort now. Instead, you felt his length sliding gently in and out, his knot kissing your hole a touch harder every time, promising what was to come. You loved the buildup to his full power. Or you used to. Today, it felt like he was just toying with you. Today, you wanted much more.
“Is that all you got?”
He didn’t say anything, but his speed doubled nearly instantly as you watched the fire in his eyes shift further from conscious thought and deeper into animalistic need. Last week, this would have been all you could handle before being forced to tap out. This week? This week you couldn’t imagine anything feeling better. Thrust after thrust pressed him past your prostate, ensuring you would be incapable of making any more snarky comments as your caged dick continued leaking pre. The feeling of being overwhelmed you had gotten used to was nowhere to be found, entirely replaced with a need for more. Whether by chemistry or coincidence, he sped up again, reading your desires as if they were his own. And of course, your desires and his were one and the same right now. It was as fast as you had ever seen anyone thrust, and though there was little you could do but whimper, it was not in pain, but in ecstasy. The power of each stroke moved your whole body back and forth, his knot slamming against you hard enough that you could feel it slipping in just a bit further each time. Never quite enough pressure for it to slip in, but then again, the fire in his eyes was still held back by his desire not to hurt you. Little does he know, the worst pain he could cause you now is by denying you the fruit of your labor. The culmination of months of effort meant you were sure he wasn’t going to cause you anything but mind-numbing pleasure. You muster all the strength you can to get out a single coherent plead between the begging whimpers forced out of you with each thrust.
“… Knot me!”
The blaze in his eyes took him over entirely. Nothing held him back as the force behind each thrust grew and grew. His knot was no longer begging to enter you. The begging was over. Now it was coming in, whether you wanted it or not. But you wanted it. You wanted it more than anything. You relaxed as much as you could with the speed and intensity of the thrusts, feeling the knot slip in nearly to the point of no return before being yanked away again. You would have begged for it if you could have. If you thought your words could reach whatever corner of his mind your boyfriend was locked away in as his instincts took care of his needs. But you didn’t have to. You both wanted the same thing. With a final thrust, his knot reached the halfway point – and passed it. Your body begged for the knot just as you did, sucking it in with the most intense feeling of fullness you could ever imagine. The view of the room went blurry as you swam in the river of intense pleasure at finally achieving your goal. You both sat for a few seconds, but when you managed to lock eyes with him, you saw that the fire was still there, even brighter than before. Before you had a chance to react, he shifted his weight and started pulling backwards. You took a deep breath in preparation for the only thing he could be planning. You may have taken the knot once, but it seemed he was far from satiated. Far too many breeding sessions to make up for forced his hand. He continued pulling out of you, nearly dragging you off the bed before the knot finally broke free with a wet squelch. You had no time to gather yourself before he was pressing it in again. As the pressure at your hole reached a maximum, you felt a lost but familiar sensation of pressure elsewhere.
*POP*
It may not be your first rodeo, but it absolutely was your second. Keeping any train of thought as his knot entered you for a second time was nigh impossible. All you could do was notice that the pressure at your hold had entered, while the pressure elsewhere got stronger.
*POP*
Out again. But the second feeling of pressure was only increasing. Months of denial left you unable to place a once-familiar sensation.
*POP*
It was getting easier, though the intense feeling of fullness nor the unknown pressure never wavered.
*POP*
“Oh god…”
*POP*
“I…”
*POP*
“I’m gonna…”
*POP*
You managed to place the second feeling just in time to open your eyes. He humped away, knotfucking you in earnest as you watched the clear pre dripping from your cage replaced with milky white cum. His knot pounding in and out of you forced out a new bead of your first orgasm since you gave him the jar of keys. Lost in the most intense feeling of pleasure you could even imagine experiencing, you could do nothing but lay there and moan your boyfriend’s praises as he used his knot to fuck the cum out of you. Your orgasm felt different this time. Unending. It was nothing like the few powerful jets of cum that felt like heaven but subsided quickly you were used to. The slow dribble of cum out of the hole in your cage felt like a constant stream of heaven. It seemed that you were destined to be at the height of your pleasure for however long he wished for you to be. It wasn’t until he locked the knot inside for the final time and collapsed on top of you that you felt it wane. He laid there for a minute as you felt spurt after spurt of warm cum shoot deeper inside you than ever before, your cage twitching and oozing out the last of your orgasm. He finally moved his hands and pressed himself off the bed. Strands of your cum clung to both your stomachs as the fire in his eyes gave way to the kind amber of your favorite person in the world. He looked down as he came back to his senses.
“Holy shit… you… are you ok? Did... did you cum from that?”
"I... that... felt so good I... I feel like I never really came before..."
You were both exhausted. He laid down again, flipping you onto his stomach while keeping the tie in place as the two of you happily basked in the afterglow. Eventually, his knot shrank enough to allow him to slide out of you, followed by a stream of cum. You climbed off and sat on the edge of the bed, still too lost in the moment to come up with anything else to say. The light from the sunset disappeared and you looked up, seeing your boyfriend stood in front of you with the jar containing the last key.
“You earned it, babe.”
He started twisting off the lid, but you stopped him before he could.
“Don’t. I… don’t want to ruin it.”
“Ruin it? Babe this was the deal we made when you-“
“I know what I said, but… This jar was my motivation to be better for you for months. I’m… attached… And that probably isn’t the right key anyway, but… it could be, you know? Opening the jar feels like… I’m done trying to be better for you. And… I’m not…”
It wasn’t often that you got to see him cry. He ducked his head and faced away from you to compose himself. That gave you plenty of time to come up with a final grand gesture. When he turned back around, you were down on one knee, holding the jar up in both hands.
“I know it isn’t a ring… but it is a promise that I wont ever stop trying to be a better person for you.”
He took the jar out of your hands, placing it aside as he hoisted you up and hugged you tight.
“Then I promise too.”
You hugged him tight before pressing yourself back to look him in the eyes.
“You realize this means my only option for getting off is you, right?”
The fire in his eyes returned almost instantly.
“Oh? You think you can handle round 2?”
“Bring it on.”
