**Hermione’s JOI: A Study in Pleasure**

I’d been studying late in the Gryffindor common room, the fire crackling low as the clock ticked past midnight. My eyes were half-lidded from exhaustion, but the second Hermione Granger slid into the chair beside me, my body woke up fast. She was still in her school skirt, legs crossed primly, but the way she bit her lip when she glanced at me? That wasn’t just studying on her mind.

“You look tense,” she murmured, scooting closer. Her fingers traced idle patterns on my thigh, and my cock twitched in my pants. “Need help relaxing?”

“Fuck, Hermione—”

“Shh.” She pressed a finger to my lips, her brown eyes dark with mischief. “I’ll tell you exactly what to do. Stand up.”

I obeyed instantly, my pulse hammering as she stood with me, her hand drifting to the waistband of my pants. “Pull them down. Let me see that cock.”

My fingers fumbled with my belt, but I got them open, shoving my pants and boxers down to my ankles. My dick sprang free, already hard and leaking. Hermione’s breath hitched as she wrapped her fingers around me, giving one slow stroke.

“Good boy,” she purred. “Now touch yourself. Just like I am.”

I wrapped my hand around my shaft, matching her rhythm. The heat of her palm against mine was electric, and I groaned as precum beaded at my tip.

“Look at you,” Hermione whispered. “So hard for me. Now stroke faster.”

I obeyed, my hips jerking as I worked myself, her breath hot against my ear. “Use your other hand,” she ordered, and I reached down, cupping my balls, rolling them roughly.

“Yes,” she moaned, watching my every move. “I want you to feel everything. Now—one finger, just under your balls. Press there.”

I did, circling the sensitive spot behind my sac, and my thighs tensed. “Fuck, that’s good—”

“I know,” she smirked. “Now, keep stroking… but slide one finger back further.”

My breath caught as I reached lower, teasing the tight ring of my asshole. Hermione’s hand tightened around my cock as she guided me. “Just the tip,” she murmured. “Push in slowly.”

I groaned as my finger breached myself, the stretch sharp and sweet. My cock throbbed in my grip, and Hermione licked her lips. “That’s it. Now fuck yourself with it while you jerk off.”

I obeyed, rocking my finger in shallow thrusts, my hips bucking into my fist. The dual sensations were overwhelming—my ass clenching around my finger, my cock pulsing with need. Hermione watched, her own breathing ragged, her free hand slipping under her skirt.

“You’re so close, aren’t you?” she panted. “I can tell. Let me hear you.”

I was beyond words, just grunting, my muscles tightening, my cock leaking onto my stomach.

“Come for me,” she demanded, her voice low and rough. “Now.”

My orgasm ripped through me, my cum shooting in thick ropes across my chest as my ass squeezed around my finger. Hermione moaned, her own fingers working fast between her legs as she watched me fall apart.

When I finally slumped back into the chair, spent and shaking, she leaned in, kissing me deeply. “Good,” she whispered against my lips. “Now clean yourself up. We’ve got more studying to do.”

And fuck, she wasn’t joking. Because with Hermione, the lesson *always* came first.
