"So Professor Reynolds, do you have time to bend me over that desk and slide that big cock into my tight little pussy before we go to class?"
My cock jerked and began to harden before I even looked up to see Maria's knockout body and resplendent face standing in my doorway. Despite my obvious physical reaction she was teasing me unmercifully, knowing full well that if someone happened to be walking close by he or she could have heard Maria's invitation.
It had been two weeks since our first sexual experience in my condo, and since then we had continued the most incredible sex almost everyday, actually often several times a day.
As always Maria was dressed to perfection. Today she had on a red miniskirt that clung to every perfect curve on her 18 year old hips and ass. A white blouse was unbuttoned just low enough to tease with cleavage from her full, high, firm, perky, B-cups. Her hair was pulled back in a ponytail that magnified her huge, deep, eyes.
Slowly she sauntered into my office, toying with me, licking her gloss-covered lips, staring unflinchingly into my eyes. She let her backpack slide off her shoulder and onto the floor next to the extra chair. Sitting in the chair Maria opened her legs, giving me a clear view of her bright red thong that clung to her perfectly trimmed, tight box.
The tiny part of my brain that had any logic left in it wanted to chide her, to tell her she can't just say things, and do things like that out in the open. She could see me struggling, but she just smiled, knowing that all I would end up doing was to close my door. And that is precisely what I did.
As I stood next to Maria she looked up at me with those big doe eyes as she slowly undid the buttons on her blouse. More than anything it was Maria's innate combination of youthful cuteness combined with pure unadulterated sexual lust that got me every time.
"Why did you close your door?" Maria teased rhetorically. By now her blouse was three quarters of the way open, her sheer, white bra contrasting against her light brown skin. Her large dark brown nipples were visibly hard, as was my cock. Taking her time Maria slowly circled her own nipples before reaching out with one hand and rubbing the tent in my khakis.
"My, my Professor Reynolds." she cooed, "From the looks and feel of this cock one would think you hadn't been laid in years." By now Maria's gaze was hungrily fixed upon my crotch as she undid my belt and slacks, dropping them to my knees.
"MMMMMMMMMMMMMMM!" she purred as her perfectly manicured nails traced over my cock through my underwear.
I let out a gasp at her touch, which prompted her adorable face to beam with delight. Slowly she jerked me through my briefs, breathing faster, her face getting flushed with desire.
"So tell me." I managed to gasp, "What was it you wanted to do before class?"
Without muttering a word Maria yanked down the last barrier to my cock and engulfed me deep into her young, eager mouth.
"OH FUCK!" I panted. Instinctively my hands grasped her head as she bobbed up and down over my shaft, sucking me deep into her throat, the vibrations of her moans only adding to the intense sensation. Knowing Maria's lust for my cock I shoved it as deep into her mouth as I could, until her lips were pressing against my skin. We stayed that way for a moment as she milked my cock with her throat. Just as suddenly she pulled her head back and released me, the office air cold on my warm, wet cock. Maria stood and sauntered to my desk, leaning her elbows onto it, her ass high in the air, barely covered by her skirt.
"I was asking if you had time to bend me over your desk and fuck my tight wet pussy." Maria beckoned.
Immediately I was behind her, lifting her skirt and admiring her round, hard ass as it cradled her bright red thong. Even after two weeks of non-stop sex I was still awed by Maria. Her 18-year-old body was absolutely perfect. She had curves, but very little fat. She was toned, and her youthful cuteness only made her sensuality more prominent. As I groped her ass with my hands I let my cock slide under her, caressing her pussy lips and clit through the soaked satin of her thong. By now Maria was so wet that the satin clung tightly to her, and as I slid my cock back and forth against her, I could feel her pussy lips embracing me through the fabric.
