**Study Break**

I should’ve been focusing on my notes—finals were coming up, and I was cramming in the library like everyone else. But the second my step-sister slid into the seat across from me, leaning forward enough for her tank top to dip and show the curve of her tits, I was done pretending to study.

We weren’t *supposed* to be like this. But ever since that night she “accidentally” walked in on me jerking off, things had changed. The way her eyes lingered on my dick, the way she bit her lip instead of apologizing—yeah, she wanted this just as bad as I did.

Now, here we were, surrounded by books and a few oblivious students in the quiet hum of the library. She kicked her flip-flop off under the table, her bare foot tracing up my calf. “You look stressed,” she murmured, too quiet for anyone else to hear.

My cock twitched in my shorts. “I’m trying to study.”

“Liar.” Her toes crawled higher, hooking under the leg of my shorts. “You keep staring at my tits.”

I swallowed hard. She wasn’t wrong. The way her nipples pressed against the thin fabric of her top made my mouth water. But the real danger was her foot, inching up my thigh now, nudging against my hardening dick. I shifted, trying to hide how turned on I was, but she just grinned and pressed down.

“Fuck,” I muttered, gripping the edge of the table.

She rubbed me slowly through my shorts, her toes teasing the outline of my cock. “We should go somewhere,” she whispered. “Somewhere… quiet.”

I knew exactly what she meant. The library had a back section—rows of old, barely-used reference books where no one ever went. I stood up too fast, my chair scraping, and grabbed my backpack. She followed, her hips swaying just enough to make me ache.

The second we were between the shelves, out of sight, I pinned her against the books. She moaned as I crushed my mouth against hers, my hands groping her tits through her top. “You’ve been teasing me all fucking day,” I growled.

She arched into me, grinding her pussy against my thigh. “Then do something about it.”

I yanked her tank top down, exposing her tits, and ducked my head to suck one nipple into my mouth. She gasped, fingers tangling in my hair as I bit down just enough to make her squirm. My free hand slid under her skirt, finding her panties already soaked.

“Fuck, you’re dripping,” I groaned.

“Because of you.” She tugged at my shorts, shoving them down just enough to free my cock. The second her fingers wrapped around me, I almost came right there.

I shoved her panties aside and shoved two fingers inside her pussy, fucking her hard and fast while she stroked me. Her breath hitched, her hips rocking against my hand. “Need you inside me,” she begged.

I didn’t make her ask twice. I lifted her effortlessly, her legs wrapping around my waist as I lined up and slammed into her. She cried out, biting down on my shoulder to muffle the sound as I pounded into her against the bookshelf.

Every thrust made the shelves rattle. Someone could walk back here any second and catch us—the thought only made me fuck her harder. She came first, her pussy clenching around me as she buried her face in my neck to stifle her moans.

I wasn’t far behind. With one last deep thrust, I came inside her, my cock pulsing as she milked every last drop from me.

Breathing hard, I eased her back down, both of us shaky. She fixed her skirt, smirking as she wiped her hand on my shirt. “Now you can focus on studying.”

Yeah. Right.
