Elle grabbed her skirt and started to push it down.
“Don’t,” I said.
She froze.
“Do you need help with anything else?” the librarian asked the student.
“This is great. It’s just what I was looking for.”
I didn’t budge as I watched the librarian return to her desk. Elle’s walls fluttered around my fingers. The student was three aisles away from us. He lowered his backpack to the ground with a soft thump.
He wasn’t going anywhere for a while.
“Cover your mouth,” I said.
Elle obeyed. My heart felt like it would hammer through my chest. This was a stupid idea. I should make her decent, and send her away.
But I couldn’t let go. It was bad enough waiting to bury my cock inside her. Getting her this close to the edge gave me tunnel vision, ignoring the risks in favor of chasing forbidden pleasure.
I picked up my pace, fingering Elle harder, faster. Her legs twitched, threatening to close on me. I used my wrist to keep her thighs open as I hammered against her g-spot.
Elle squirmed, whimpering into her palm clamped tightly against her mouth. When I grazed my thumb against the stiffness of her clit, I could tell she was so close.
“Turn around,” I said.
On shaky legs, Elle turned to face me. I curved my hand around the back of her neck and tucked her into my chest. My gaze continually scanned the library for surprise visitors as I slotted my fingers inside her again.
“Fuck,” I whispered. “You’re squeezing so tight, love. Go on. Come all over my fingers. Show me just how desperate you are for my cock.”
Elle whined and clawed at my chest, burrowing into my shoulder. Her body seized, clenched. I curled deep into her pussy, grinding the heel of my palm against her clit. She shattered with a muffled scream against my shirt.
Dark satisfaction curled around my spine. I whispered sweetly against Elle’s hair, holding her as she shivered with aftershocks. When her legs wobbled, I wrapped an arm around her waist for support. Her exposed nipples rubbed against my torso.
The student gathered his backpack and walked away, leaving us blissfully alone again.
Elle raised her head, blinking the lusty haze out of her eyes. I cupped her face in my hands and kissed her forehead, the tip of her nose, and finally her lips. She smiled like a cat drunk on cream.
“Can I return the favor?”
When she reached for my belt, I stopped her and shook my head.
“That was enough risk-taking for one day.”
“I’ll be quick,” she promised.
“Keeping you cock-hungry seems to be motivating you very well,” I pointed out. “I wouldn’t want you to lose your momentum.”
Elle huffed with exasperation. I laughed softly.
“But I’ll take a memento to remember the occasion,” I offered.
Kneeling before her, I slid my hands up her legs. Then I tugged her panties down and tucked them in my pocket. Smoothing her skirt into place, I rose to my feet and gave her ass a little pat.
“Back to work, Miss Roche,” I said. “I’ll see you another time.”
Elle beamed and caught my hand as she passed, giving it a squeeze.
“I look forward to it, Professor.”
