Speedy

You speed up the tiny two-finger strokes exactly the way she showed you, the pinched twist growing quicker and more frantic. Your cock head keeps popping in and out between your thumb and index finger, shiny and red, looking even smaller with every short motion. Precum drips in a steady string to the floor.

“I’m—close,” you warn her, voice already shaking. “Really close—”

Your sister only smiles, arms still crossed, eyes locked on the humiliating little motion.

“Then finish. Right there. Two fingers only. Don’t you dare use more.”

The permission is all it takes. Your hips jerk once. A choked sound leaves your throat as your cock pulses hard between the tight pinch of your fingers. Thick ropes of cum spurt out—far more than the modest size of your cock seems capable of producing—splattering across the laundry-room floor in several long stripes. The last few weaker spurts land across the back of your middle finger and drip down onto the tile.

You keep the tiny strokes going through the whole orgasm, milking every drop the way she ordered, until your cock is oversensitive and still twitching in the small circle of your fingers. The floor between your feet is a glossy mess. Your middle finger glistens with your own cum.

You’re left standing there naked, breathing hard, cock still half-hard and shiny, the evidence of how quickly you finished spread across the tile and your own hand.

Your sister looks down at the mess, then back up at your face. Her expression is pure satisfied amusement.

“That was fast. And messy.” She nudges one of the thicker streaks on the floor with the toe of her sock. “You’re not leaving that for someone else to step in. Lick it up.”

The order is calm, almost casual, but there’s no joke in her voice this time. She just waits, watching you, still fully clothed while you’re naked, spent, and dripping.

Your cock gives one last weak twitch at the command. The taste of your own cum is already in your imagination. The laundry room is quiet except for your breathing. No one else in the house seems to have noticed anything yet.

What do you do?

Drop to your knees right away and start licking the cum off the floor like she ordered, beginning with the biggest streaks, while she stands over you and watches.

Hesitate, face burning, and start with the cum on your own middle finger first—licking that clean while you decide whether you’re really going to do the floor.

Stay standing and try to talk your way out of it, even though your spent cock is still on full display and the mess you made is right there between your feet.
