The door opened and her head peeked in. "Professor? You wanted to see me?"
He looked up from his desk and nodded, watching her walk into his office. Dressed as usual in a short skirt and a button-down shirt with too many buttons unfastened, she always exuded an air of promiscuity.
Sitting down in the chair facing his desk, she didn't bother crossing her legs, but left them splayed lewdly open, allowing him a glimpse of her creamy inner thighs and a hint of further delights.
Closing his book, he looked at her, resolutely trying not to leer at her exposed cleavage. "Yes. I wanted to talk to you about your manner of dress. It's much too provocative for the classroom. Most of the guys are not paying attention to the lecture, but what it would feel like to fuck your tight little pussy."
"Professor!" She spluttered, shocked at his forward language.
"Oh hush. You know it's true. Why else would you dress like a whore if you didn't want to be treated like one?"
"Well, professor," she said was a hint of resolve in her voice, "I like the way I dress, and I like how I feel when I'm dressed like this, so I'm not going to change. What are you going to do about that?"
"I'm going to do exactly what you want me to do." He said ominously. "Now stand up and put your hands flat on my desk."
With a defiant toss of her hair, she complied, sticking her ass further into the air than necessary, which was completely fine by him.
Her defiant look slipped a little when she saw him pull a wooden ruler out of his desk.
"What...?" She started, but trailed off with a gasp when he flipped up the back of her skirt to expose the perfect globes of her ass, the black thong she was wearing nestled enticingly between her cheeks.
"I'm going to spank you ten times with this, and you're going to count each one and thank me for it. Is that clear?"
She nodded, cowed by his authoritative manner. He smiled. Her submissiveness will be very useful shortly.
"Oh, I forgot one thing." He trailed off as he reached into his desk drawer and pulled out three large binder clips. "I need to put these on first so you truly know how a whore is treated."
Reaching forward, he turned her to face him, then pulled apart the hem of her shirt, ripping it open to expose her breasts. He knew she wasn't wearing a bra underneath by the visibly hard nipples poking up against the cotton.
She whimpered as he rolled her nipples in his fingers, making them stand up straight and proud. Hissing, she tried to squirm away as he affixed the clamps to her swollen buds, but was unsuccessful. The clips cut off the blood supply making her nipples throb painfully. Kneeling between her legs, he found her clit already pronounced, and closed the clip around it causing her to buck with a cry. Turning her once more, he made sure her hands were flat against the desktop.
CRACK! "One. Thank you sir."
CRACK! "Two. Thank you sir," she gasped.
CRACK! "Four... thank you sir." He paused.
"You forgot three. Surely you haven't had enough already?" She could hear the pleased tone in his voice.
CRACK! "Four. Thank you sir," she repeated. He caressed her reddening cheeks.
"No. You're still on three. You need to count properly."
She moaned. CRACK! "Three. Thank you sir."
With each blow, her ass began to darken, and by ten her skin was bright red and almost hot to the touch.
Sliding a hand between her legs, he found her panties were soaked through. "I knew it. A true whore." She whimpered audibly.
He grasped the hem of her panties, pulling them down her legs, baring her bare mound to his view. He slid first one than two fingers inside her dripping pussy, hearing her moan. Fingerfucking her gently, he was pleased at how wet she was.
Abruptly he pulled his fingers from her and she heard a rustle behind her, and the crinkle of a condom wrapper opening.
