I lock my lips together, resisting the pressure of his lace-clad fingers.
“Open your mouth, brat.”
“Mmmf!” I refuse, not daring to speak aloud in case me manages to slip the perverted gag in place.
“You’ll knock on the desk if you need me to stop.” He’s determined now. Merciless. “Open. Your. Mouth.”
His fist tangles in my hair, wrenching my head back.
I gasp, and it’s not entirely involuntary.
He presses the wet underwear between my parted lips. I moan at the taste of my own arousal.
“You like how you taste, don’t you?” he asks, voice almost guttural with his tormented lust.
His hand clamps over my mouth, trapping the makeshift gag behind my teeth.
“Sayyes, Professor,” he commands.
But I can’t speak. My mouth is full of torn lace.
He keeps the muffling hand in place and spanks me with the other. “I gave you an order.”
“Yes, Professor.” My cheeks flame at the garbled attempt to comply.
He caresses my ass. “See? That wasn’t so hard. You can be my good girl.”
A low growl eases from my chest, but I’m too turned on to be truly indignant.
“What was that?” Three stinging swats to my upper thighs.
I shriek at the flash of white-hot pain.
“Shhh,” he reminds me, dipping his face close enough to mine that his lips ghost over my forehead. “You don’t want to get caught, do you?”
Two fingers touch between my legs, testing the fresh wash of desire that wets my labia.
“I think maybe you like that idea a little too much.” Abruptly, he grasps my pussy in his broad palm—a purely possessive act. “Too bad. I’m not going to let anyone else see you like this.”
I whimper at a rush of lust.
“I think you like that even better,” he remarks, teasing my folds. “Do you want me to be possessive? Do you want me to promise I’ll ruin you for all other men and keep you for myself?”
I try to shake my head, but the little thrill of alarm that races down my spine heats my core.
“It’s a good thing you’re gagged. I wouldn’t like it if you lied to me. This is for your own good.”
I growl at him again, but he just rubs my butt fondly.
“You’re really cute when you’re pretending to be fierce. You can let go now. Just relax and submit. I promise I’ll make you feel good.”
Stinging heat flares on my upturned ass when he spanks me again to punctuate his point. At the same time, he kisses my forehead. The dichotomy of tenderness and torment makes my brain go fuzzy, and I melt into the desk.
“That’s my good girl,” he praises, swatting my thighs again. “Just like that.”
The sweet pain stops abruptly, and he traces the outline of my throbbing pussy.
“Now,” he drawls. “I’m going to let go of your mouth, but you’ll behave and keep your panty gag in. Don’t disappoint me.”
