You reach out and take the soft pink panties from her hand.

The fabric is warm from being held and carries a faint, intimate scent—your mom’s detergent mixed with something more personal. Without thinking, you bring them up to your face and inhale.

The smell hits you hard. Your soft cock gives an immediate, helpless twitch… then starts to shrink.

Your sister’s eyes light up.

“Did you just sniff Mom’s panties right in front of me?” She laughs, delighted. “Oh my god. You’re even more of a pervert than I thought. Now clean up your mess with them, panty-sniffer.”

Face burning, you drop into a squat to reach the cum on the floor. The position is a mistake. As soon as your knees bend and your thighs open, your already-soft little cock turtles hard—pulling back until the head disappears completely and only a smooth, slightly puffy mound of skin and balls remains. It looks like you have nothing at all between your legs.

Your sister’s laugh turns sharper.

“Holy shit. It just turtled. Your dicklet got so embarrassed it ran and hid inside you.” She steps closer, staring openly at the blank space where your cock used to be. “That’s the cutest and most pathetic thing I’ve ever seen. You can’t even keep it out while you clean.”

She points at the floor.

“Hands and knees. Now. I want a better view while you scrub.”

You hesitate only a second—the phone threat still fresh—then lower yourself all the way down onto your hands and knees on the laundry-room tile. The new position makes the turtling even more obvious. Your balls hang free, but your cock is fully inverted, nothing but a shy little slit visible between them. The pink panties dangle from one hand.

“Good boy. Now wipe. Slow. I want to watch that empty little mound while you work.”

You press the crotch of your mom’s panties against the first thick streak of cum and start scrubbing. Every forward movement makes your turtled cock stay hidden; every shift of your knees keeps it inverted. Your sister circles you slowly, phone still in her pocket but the threat unspoken now that you’re obeying. She makes soft, amused comments the entire time.

“Look at it. Completely gone. Just balls and a sad little crease. Even your own cum isn’t enough to make it come back out.” She nudges your hip with her foot. “Keep scrubbing. Get every drop into Mom’s panties. Don’t stop until the floor is perfect.”

You work on your hands and knees, face burning, while the soft pink fabric grows heavy and sticky with your load. The smell of the panties mixes with the smell of your cum right under your nose. Your cock stays turtled the entire time, as if it has decided the humiliation is safer inside than out.

When the last streak is gone she finally lets you stop.

“Up. Bra next.”

You rise on shaky legs. Your cock remains mostly inverted, only the tip cautiously peeking out again now that you’re standing. She holds the matching pink bra open and watches while you slip your arms through the straps. She hooks the clasp herself, tugging the band snug against your flat chest so the empty cups sag in a way that feels deliberately mocking.

“Now the messy panties.”

You step into the cum-soaked panties and pull them up. The wet, cold crotch presses against your still-turtled cock and balls, forcing the soft mound into the sticky fabric. The panties are tight enough that everything is compressed forward; the dark wet spot spreads immediately. Your cock gives a weak attempt to fill out again but stays small and half-hidden under the soaked material.

Your sister steps back and looks you over—Mom’s bra, Mom’s cum-filled panties, your little dick still trying to turtle inside the sticky crotch.

“Perfect,” she says softly. “Now get dressed. Jeans and shirt on top. The bra and panties stay exactly where they are. I’m checking later, so don’t even think about taking them off.”

She tosses your clothes at your chest and waits, eyes gleaming, while the wet panties cling to your turtled cock with every small movement.

What do you do?

Pull your jeans and T-shirt on over the bra and sticky, cum-soaked panties without further comment, accepting that you’re spending the rest of the day like this under her watch.

Look down at the way the wet panties hug your still-turtled cock and balls, clearly affected by the sight and the smell, before slowly getting dressed while she watches every second.

Quietly ask her what happens if the panties stay this wet… or if Mom notices her missing bra and panties later.
