**Tent Lessons**

The summer air was thick with humidity, the kind that made your skin stick to everything. Me, my younger sister Lily, and Mom had gone camping—just the three of us. Dad was out of town, and Mom had this *thing* about teaching us survival skills. But tonight, after a few too many sips from her flask, she’d crawled into her own tent early, leaving Lily and me alone by the fire.

Lily was eighteen—younger than me by three years—but she wasn’t a kid anymore. I’d noticed. Hard not to. The way her shorts hugged her thighs, the way her tank top slipped off one shoulder when she stretched. She’d caught me staring more than once, biting her lip like she knew exactly what I was thinking.

I should’ve felt guilty. I didn’t.

The fire burned low, and Lily yawned. “Guess we should turn in.” Her voice was soft, teasing.

Our tent was small—Mom had insisted we share to save space. Inside, the air was even hotter, the nylon walls trapping our breath. Lily unzipped her shorts, sliding them down her legs with a slow, deliberate tug. My dick twitched in my jeans.

She turned, catching me staring at her panties—thin cotton, barely covering her pussy. “You like what you see?”

My mouth was dry. “Fuck, Lily.”

She smirked, crawling toward me on her hands and knees. “Mom said we should learn from each other, right?”

Before I could answer, her fingers were at my belt, tugging it open. My cock sprang free, already hard. Lily licked her lips, wrapping her hand around me. “She never taught me *this*.”

I groaned as her fingers squeezed, her thumb swiping over the head of my dick. Then she leaned down, her tongue flicking against me. The first warm wetness of her mouth made my hips jerk. “Jesus, Lily—”

She took me deeper, her lips tight, her tongue swirling under the tip. I tangled my fingers in her hair, guiding her down. She gagged a little, pulling back, but her eyes were dark, hungry. “You taste good,” she whispered.

I couldn’t take it. I flipped her onto her back, yanking her panties to the side. Her pussy glistened in the dim light, already wet. “You want this?” I growled.

She spread her legs wider in answer.

I pushed two fingers inside her, her cunt clenching around me. She gasped, arching her back. “Fuck, yes—*please*—”

I lined up my cock and pushed in slow, stretching her. She was so tight, so fucking warm. Her nails dug into my shoulders as I bottomed out. “**Oh god**,” she whimpered.

I started moving, each thrust making her whine louder. Her legs wrapped around my waist, pulling me deeper. She was so wet, her pussy sucking me in with every stroke.

Then—a sound outside. A zipper.

Mom’s voice, drunk but clear. “You two need help with your *lesson*?”

We froze.

The tent flap opened. Mom crouched in the entrance, her eyes locked on where my cock was buried inside Lily. She licked her lips.

“Good girl,” she murmured. “Now let me show you how to *really* take care of your brother.”

Lily moaned as Mom’s fingers replaced mine, guiding my thrusts harder, faster.

And I realized—this was one lesson we *all* needed.
