I start moving with slow, deep strokes that make the desk creak ominously. Her glasses are fogging up from her panting against the wood surface.
"Look at you. Proper little librarian taking cock like she was made for it. What would Mrs. Patterson think if she could see you right now?"
"Don't care," she gasps. "Don't care what anyone thinks."
I reach around, find her clit, circle it slowly while I fuck her. "No? Don't care if someone walks in? Sees you bent over your own desk with my cock buried deep in your cunt?"
She clenches so hard around me I can barely move. "Oh god, oh god—"
"You'd like that, wouldn't you? Being caught. Everyone knowing you're mine. Everyone seeing exactly what kind of good girl you really are."
I fuck her harder now, the sound of skin slapping against skin obscene in the quiet library. She's biting her hand to stay quiet but little whimpers keep escaping anyway.
"Touch yourself," I order. "Rub that clit while I fuck you. Make yourself come on my cock."
Her hand moves between her legs immediately, and I can feel her fingers brushing against my cock as I slide in and out of her.
"Such a good girl. Following orders perfectly. Taking Daddy’s cock so fucking well."
"Sir, I'm close— so close—"
"Not yet. You don't come until I give you permission. Hold it."
I pull out completely and she whines at the sudden loss, her pussy clenching on nothing.
"Turn around. On your knees. Now."
She drops immediately, mouth opening automatically. Eager. Perfect. I feed her my cock, let her taste herself on me.
"That's it. Clean your mess off Daddy's cock. Taste how desperate you were for me."
She moans around me, takes me deeper into her throat. I fist my hand in her hair, pulling that bun apart finally, watching her hair tumble down around her shoulders.
"Enough. Stand up."
I pull her up, lift her onto the desk easily. Spread her legs wide and thrust back in hard. From this angle I can see everything - her face, her bouncing tits through the thin blouse, the way her pussy stretches around my cock.
"Watch," I order. "Watch me fuck you. See how well you take me."
She looks down, watches my cock disappear into her over and over, her eyes wide with fascination.
"See how perfect we fit? How your greedy little cunt swallows my cock like it was made for it?"
"Yes, Sir! I see it!"
I thumb her clit while I fuck her, feeling her get closer and closer to the edge. She's clenching rhythmically now, her whole body tensing up.
"You want to come? Want to come all over Daddy's cock?"
"Please! Please, Sir, please let me come!"
"Beg properly. Convince me you deserve it."
"Please let me come on your cock, Sir! I've been so good, followed all your rules, done everything you asked! Please, I need it so badly, please!"
"Come. Come right now for me."
She explodes, her pussy clenching so tight around me I can barely move. I fuck her through it, prolonging every wave until she's shaking and sobbing with overstimulation.
