Barbara was my most advanced graduate student. She and I had been working together on a project for two months and were finally reaching the end. This was the third day in a row that we worked late into the night, until long after the other faculty and staff had left. It was almost midnight when we shut the computer down. Barbara swung her chair around, away from the desk and stretched her arms up, over and behind her head and flexed her back muscles, sighing from the pleasure of the relief she felt from the stress of working over the keyboard. I sighed from the pleasure of the sight of her full breasts straining against her lacy bra and the thin material of her white blouse. Her skirt, a short, tight black one that showed off the curves of her thighs and ass, had slid up her thighs to reveal just the beginnings of dark stocking tops. I could feel my cock hardening as I thought about what kind of garter belt and panties she might be wearing.
"What are you looking at, professor?" Barbara asked with a mischievous grin. I guess I had been staring at her longer than I had thought. I looked at her sort of sheepishly, feeling my face flush in embarrassment. "Don't be shy!" she urged. "You certainly seem to like what you see!" she said, reaching out to rub my hardening cock through my slacks. I couldn't believe it. "Mmmmm," she moaned as she felt me growing bigger.
I bent down and slid my hands up the outsides of her thighs and under her skirt, pushing it higher to reveal the tops of her black stockings and the black garters holding them up. I massaged the bare flesh above her stockings as I moved my hands between her legs and pushed her thighs apart.
"Stockings and garter belts are so sexy!" I told her.
"Go for it, professor," she urged me, in a husky whisper.
I dropped to my knees and buried my face in her crotch. I licked her inner thighs, running the tip of my tongue along the edge of her panties, inhaling deeply the sweet mix of perfume and her arousal, tasting her slightly salty flesh and feeling the softness on my tongue of the blonde hair protruding from the crotch of her white lace panties.
I slipped my hands up her hips to the tops of her panties and pulled them down gently, and slowly. Barbara lifted herself slightly to let me slide the panties over her ass. I inched them down her thighs, savoring the slow exposure of her pussy, and the strengthening scent of her arousal. This is the moment I savor: Panties, still warm and moist, sliding slowly, slowly down to expose a wet pussy; a woman looking at you with lust-filled eyes as you begin to salivate in anticipation of how she will taste. Barbara's legs came together to let me get the panties over her knees. I lifted her left knee up and pushed it out to the side, slipping the panties over her left foot. I left them hanging around her right ankle as I lifted that knee up and spread it to the side, too. We stared into each others' eyes as I whispered, "I'm going to eat your pussy."
