My Sister-in-Law wants to shrink my Dick
An SPH Experience by clittydicksub.
Leanne (my wife) had joked about it in bed once or twice, calling it my “cute little nub,” but I never thought she’d broadcast it. Turns out, during a family dinner a couple months ago, she let slip how she’d been ‘deprived’ of a real man’s equipment, and suddenly her mom, sisters—everyone—was in on the secret.
The laughter that night still echoes in my nightmares: her oldest sister, Kate, snorting wine through her nose, and the middle one, Jess, patting my knee like I was a kid with a skinned elbow. ‘Poor guy,’ they’d cooed, but their eyes sparkled with wicked amusement. I played it off, face burning, but deep down, that mix of shame and thrill stirred something in me. Small penis humiliation had always been my dirty little kink, hidden away in porn tabs I’d close in a panic. Now it was out there, real and raw.
Things escalated just over a week ago. I was at a buddy’s place, watching the game, when my phone rang. It was Leanne, her voice slurry from wine. ‘Hey, honey, come home. The girls are over for girls’ night, and we… we need you.’ There was giggling in the background, and something about her tone made my gut twist. I made excuses to my friend and drove back, heart pounding. What could they possibly want?
I walked into our living room, and the scene hit me like a slap. Empty wine bottles cluttered the coffee table—three, maybe four—alongside half-eaten takeout containers. Leanne, Jess, and Kate lounged on the couch in their pajamas, faces flushed, eyes gleaming with mischief. Jess held a yellow tape measure in her hand, dangling it like a prize. The air smelled of garlic from Chinese food and the sharp tang of Chardonnay.
“Oh, there he is!” Kate clapped, her voice too loud. “Come on in, little bro. We’ve been talking about you.”
I froze in the doorway. “What’s going on? Girls’ night over already?”
Leanne grinned, that predatory smile she gets when she’s tipsy and dominant. She patted the spot next to her. “Sit. We’ve heard all about your… situation from Leanne, but we need proof. Come on, we actually need to measure this.” Jess waved the tape measure, her words slurring just a bit.
“I cannot believe it really is that small,” Leanne added, leaning forward, her eyes locked on my crotch. She was grinning like it was the best thing to ever happened to her. “If it’s less than two and a half soft, or five inches hard—we have a plan.”
The giggling erupted then, intense and unrelenting, like hyenas circling prey. Jess doubled over, Kate wiping her eyes.
My face went hot. “What? No, this is crazy. I’m heading back out.” I turned to leave, but Leanne was on her feet in a flash, grabbing my arm with surprising strength.
“Oh no, you don’t,” she said, her voice firm. “You’re not backing out. Strip. Now. Or I’ll do it for you.”
Her sisters hooted encouragement, and I felt trapped, my cock already twitching traitorously at the humiliation. Part of me wanted to bolt, but the bigger part—the kinky, masochistic part—urged me to obey. With shaking hands, I pulled off my shirt, then my jeans, kicking off my shoes. Finally, my boxers. There I stood, naked in my own living room, my soft little dick bobbling pathetically between my legs, balls tight against my body from nerves.
The laughter exploded.
It was immense, echoing off the walls—high-pitched squeals and deep belly laughs that made my skin crawl. Kate had tears streaming down her face as she fanned herself. “Oh my God, it’s even tinier than I imagined! Look at that little worm!”
Jess leaned in close, pointing. “Aww, poor baby. Does the itty-bitty pee-pee feel shy?”
They cooed mock sympathies, baby-talking me like I was a toddler: “Who’s a wittle guy with a babydick? You are!”
I covered myself with my hands, mortified, but Leanne swatted them away. “Hands off. Let the girls see.”
Then, to my horror, they grabbed forks from the takeout—still greasy from lo mein—and started prodding. Jess poked the tip of my dick, not gently at all, making it jiggle. “Boop! Look how it dances!”
Kate jabbed at my balls, light but stinging. “These are cute, though. Like little grapes.”
I yelped, stepping back, but the prods kept coming, each one sending jolts of humiliation through me. My dick, the bastard, started to stir, thickening slightly from the attention.
“Alright, measurement time!” Jess announced, uncoiling the tape.
But Leanne held up a hand. “Wait—he’s getting a little excited. That’s not fair. We need an accurate soft reading.”
Before I could protest, Kate dashed to the kitchen and returned with a bowl of ice from their drinks. “Ice reduction it is!”
They pushed me onto the couch, and Jess pressed the cold bowl against my groin. The shock was brutal—freezing water and ice cubes numbing my skin instantly. I gasped, my half-hard cock shrinking back like it was fleeing. “F-fuck, that’s cold!”
But they held it there, giggling as it wilted. After a minute, they pulled it away, and Jess knelt, tape in hand.
She stretched it along my shriveled length, from base to tip.”‘ One… one and a quarter inches,” she read, her voice dripping with delight.
The squeals were deafening—pure joy at my expense.
Leanne high-fived her sisters. “Told you! Our little micro-man.”
I sat there, humbled to my core, the cold making my balls ache, my dick a frozen nub that barely existed. The laughter washed over me, stripping away any dignity I had left.
That was when the trap sprang. Kate, still catching her breath, pulled out her phone. “Girls, I read this article—something about chastity cages. If you lock a guy up in smaller and smaller ones, it can actually shrink the damn thing over time. Like, train it to stay tiny.”
Leanne’s eyes lit up. “Perfect. Let’s keep it at this size—or smaller—by caging it. And then, at Christmas, we expose how small we get it to the whole family. It’ll be the best present ever—unwrapping the truth about our little-dicked hubby!”
I shot up, panic rising. “No way! This isn’t fair—you can’t just—”
“Oh, but we can,” Leanne interrupted. “Family vote. All in favor of caging and Christmas reveal?”
Hands shot up: Leanne, Jess, Kate—three to one.
I was the only nay, my vote was meaningless.
“Outnumbered, tiny,” Jess teased, ruffling my hair. “Time to accept your fate.”
Now, with the cage—a pink plastic thing Leanne ordered overnight—locked around my shrunken dick, I count down the days to Christmas. Every rattle reminds me of that night, the prods, the ice, the vote. Part of me dreads the family gathering, all those eyes on my exposed shame, laughing as they pass it around like a joke gift.
But the twisted thrill? It keeps me leaking in my cage, craving the humiliation. Yeah, I guess I have to accept it. The whole family laughing at my tiny, caged dick on Christmas Day? It’s coming, whether I like it or not.
The End.
