**TITLE: Bathroom Bondage with My Little Sis**

The bathroom was steamy, the mirror fogged up from the shower I’d just taken. I was still dripping when I heard the door creak open behind me.

“Oops,” my little sis giggled, but she didn’t leave.

She was supposed to be at cheer practice, but here she was, still in her tiny skirt and crop top, biting her lip like she knew exactly what she was doing.

“I told you to knock,” I said, but my cock was already stirring.

She stepped closer, her eyes dropping to my towel. “You’re not hard yet? Disappointing.”

That did it. My dick swelled instantly, making the towel tent. She grinned.

Then she reached into her bag and pulled out a coiled-up rope.

“You’ve been planning this,” I muttered.

“Maybe.” Her fingers trailed down my chest. “Or maybe I just wanna make sure you don’t run away before I’m done with you.”

She pushed me back against the counter, her small hands surprisingly strong as she tied my wrists behind my back. The rope bit into my skin—not too tight, but enough to remind me I was hers right now.

Her fingers dipped under my towel, wrapping around my cock. “There we go,” she murmured, stroking me slowly. “Already so hard for me.”

I groaned as she dropped to her knees, her mouth closing over the tip of my dick without warning. The heat of her tongue made me buck my hips, but she held me down, her fingers digging into my thighs.

She sucked me deep, her throat flexing around my cock as she took me all the way in. I could feel her gag a little, but she didn’t stop. Fuck, she was good at this.

“You’ve been practicing,” I growled.

She pulled off with a wet pop. “Wanted to surprise you.”

Then she untied my hands just long enough to spin me around and shove me against the counter again, this time forcing me to bend over. Her hands gripped my ass as she yanked her skirt up, and I heard the unmistakable sound of her panties sliding off.

Her pussy was dripping when she pressed it against my ass, grinding for a second before guiding my cock between her slick folds.

“Don’t move,” she whispered, then slammed herself down onto me.

I groaned as her tight cunt squeezed around my dick, her hips rolling in slow circles. She was so fucking wet, every movement making obscene squelching sounds.

But she wasn’t done.

After a few minutes, she pulled off, panting, and turned around, bending over the counter this time. “Fuck me from behind,” she ordered.

I didn’t hesitate. I grabbed her hips and plunged back into her, my balls slapping against her ass as I started thrusting hard. She whimpered, her fingers clawing at the counter, and I knew she was close.

“Touch your clit,” I growled, and she obeyed instantly, rubbing circles over her swollen little nub as I fucked her deeper.

Then she came with a cry, her pussy clamping down around me so tight I couldn’t hold back. I buried myself inside her as I came, pumping every last drop into her.

We collapsed against each other, breathless.

She turned her head to smirk at me. “Bathroom’s gonna need another shower.”

I just groaned, already half-hard again.

Fuck. She was gonna be the death of me.
