Lynn leaned in close to her sister Leah, voice low and wicked. “You want to fuck around on Bryan and be wild and slutty like we were before you got married? Lock his cock up for a month and tell him it will make the sex hotter, it will actually shrink his dick and make him easier to manipulate.
Leah laughed, but the idea stuck. That night she crawled into bed with Bryan and straddled his hips. “Baby, I want to try something. Put this cage on for thirty days. When I unlock you, the sex is going to be insane. You’ll be so backed-up you’ll flood me and probably get me pregnant.”
Bryan hesitated, but Leah’s hand stroking his already-hard dick sealed it. “You promise it’ll feel better?”
“Promise,” she purred, snapping the cage shut. “I’ll measure you every month so we can see how horny you get.”
Leah didn’t mentioned the secret: each month the cage would steal an inch.
Thirty days later Leah unlocked him. His cock sprang out, flushed and angry, but it was clearly shorter—seven inches instead of eight. She wrapped her fingers around it and gasped. “Holy shit, Bryan, it’s smaller.” Her pussy clenched at the sight. Instead of stopping, she wanted more.
She shoved him onto his back and climbed on. “Let’s see if you can still reach everthing.” She sank down, taking his reduced length. “Fuck, I can already feel the difference. Your little dick isn’t hitting the same spots.”
Bryan groaned, thrusting up, but Leah rode him hard, laughing. “Pathetic. One month and you’re already losing ground. How much smaller are you gonna get before you can’t even make me cum?”
She ground her clit against what was left of him, soaking his shorter shaft. “God, I love feeling you shrink. Next month I want to watch to see if it disappears even more.” She leaned down, biting his ear. “Maybe I’ll start calling it your baby dick.”
Bryan came fast, humiliated and desperate, pumping a huge load into her. Leah kept rocking on his softening nub, smirking. “Already done? With your full-size cock you used to last longer. Now look at you—seven sad inches and you blow in two minutes.”
She climbed off, cum dripping down her thighs, and grabbed the measuring tape again. “Let’s mark this. Seven inches. Can’t wait to see what next month looks like.”
Leah told her sister Lynn everything so naturally Lynn asked how was the sex after 1 month, “It was terrible Lynn his cock shrunk a whole inch, I could still feel him but it was no where near as good as it used to be”. If he let you lock him back up he probably secretly likes you doing this to him you should threaten to start dating if he get smaller, that will either stop the shrinking or he will keep getting smaller because he wants it to” Lynn replied
Leah unlocked the cage one month later and Bryan’s cock flopped out, red and swollen from two months of denial. She measured his dick and read the numbers out loud. “Six inches. You lost another one, baby. Look at that sad little thing.” She flicked the head with her fingernail and laughed when it twitched. “Two months and you’re down to six. At this rate you’ll be a four-inch joke by month four.”
Bryan stared at the tape, face burning. Leah climbed onto the bed naked, spread her legs, and pointed at her glistening pussy. “Get on top and try to fuck me. Let’s see if six inches can even reach my cervix anymore.”
He climbed between her thighs, lined up, and pushed in. The difference was obvious the second he bottomed out—her cunt swallowed every inch and still had room to spare. Leah moaned dramatically. “Oh my god, I can feel the gap. Your old eight-inch cock used to punch my cervix. Now this six-inch nub just sits there like it’s lost.”
She wrapped her legs around his waist and pulled him deeper, grinding her clit against what was left of his shaft. “Fuck me harder, tiny. Maybe if you slam it in fast I won’t notice how short you are.” Bryan started thrusting, desperate, but every stroke felt shallow. Leah kept talking. “You used to make me scream. Now you’re just stirring my pussy like a teaspoon. I can already tell I’m not going to cum from your dick tonight.”
Bryan’s face was crimson. Leah reached down, grabbed his balls, and squeezed. “Answer me honestly. If this keeps shrinking and you’re left with five inches or less, can I go out on a date?”
He froze mid-thrust. Leah squeezed harder. “Tell me yes. Tell me you’ll let me date if your cock shrinks down to five inches.”
Bryan’s voice cracked. “Y-yes. If it gets that small ... you can go on a date.”
Leah’s smile was vicious. “Good boy. Because at this rate you’re going to be a three-pump disappointment with a four-inch clit by summer. I’ll need someone who can actually stretch me open while you sit at home leaking in your cage.”
She rolled him onto his back and straddled him, sinking down until her ass cheeks slapped his thighs. “Look at you, already throbbing like you’re about to blow. Two months of blue balls and six sad inches and you’re ready to squirt the second I ride you.” She bounced hard, making wet slapping sounds. “I can feel every inch missing. Your cock used to knock on my womb. Now it’s just tapping the front wall like it forgot where to go.”
Bryan grabbed her hips, trying to thrust up, but Leah pinned him down. “Stay still. Let me use what’s left of you.” She ground her clit against his pubic bone, soaking his short shaft with her juices. “God, you’re such a bad fuck now. I used to cum three times on your big dick. Tonight I’m not even close.”
She leaned forward, tits swinging in his face. “Maybe next month I’ll bring a measuring tape on my date. Show the new guy how small you’ve gotten. Tell him my husband’s cock is shrinking so I need a real man to keep me satisfied.” Bryan groaned, humiliated, and Leah felt his cock twitch inside her. “That’s it, tiny. Cum for me while I plan my first date. Fill me up with that weak six-inch load so I can feel how much less there is.”
Bryan came with a choked cry, pumping thick spurts into her. Leah kept rocking, milking every drop while his cock softened inside her. “Already done? With six inches you can’t even last two minutes. Imagine how fast you’ll cum when you’re down to four.” She climbed off, cum dripping down her thighs, and grabbed the tape again. “Six inches marked. Can’t wait to see five next month. Maybe I’ll start shopping for lingerie for my date while you’re still locked up.”
Once again Leah and Lynn talked,” he’s down to 6 inches Lynn and I’m starting to get horny, It’s working, he’s shrinking, but i need need a big cock inside me soon or I’m going to burst”. “Did Bryan agree to letting you go out on a date if it shrank another inch next month” Lynn asked. “Yes he agreed to it” Leah replied. “Good we will make it a girls night, me and you are going to that hot new club downtown”.
Leah unlocked the cage on day ninety and Bryan’s cock tumbled out, even smaller than before. She read the measuring tape and read the number with a cruel little laugh. “Five inches. Look at that pathetic baby dick. Another inch gone and you’re barely bigger than my middle finger.”
Bryan swallowed hard, face burning. Leah shoved him onto his back and climbed on top, lining his shrunken shaft up with her already wet pussy. She sank down in one smooth motion and moaned dramatically. “God, I can barely feel you. Five inches is a joke. Your old cock used to stretch me open. Now this tiny thing just sits inside me like it’s lost.”
