They walked into the darkened lobby at about one in the morning, he leading her by the hand. As the doors closed behind them, they made straight for the elevator bank, crossing the dimly-lit open space as quickly as possible. After jabbing the button for the fifteenth floor, they quickly wrapped their arms around one another and spent the whole trip up in a long, passionate kiss. Both of them were clearly looking forward to this little excursion.
Out of the elevator and down the long hallway, then, after a quick peek to make sure no one was watching. Once inside room 1510, he closed the door.
"So, this is where you have Western Civ?"
"Yes," she replied. Right here, three days a week at nine in the morning."
He dropped an overstuffed backpack to the floor beside the teacher's desk.
"And this is where you want to be?"
She grinned as her eyes adjusted to the dim lights of the room, dialed down for the evening but never turned completely off. The university was well-endowed and quite proud of this newest building, and it stood out as a faintly glowing tower throughout the night.
"This is exactly where I want to be," she purred, unbuttoning his shirt. "This class is so boring - most of the time, I just drift off and dream about making love to you, right there on the desk."
"So, I guess this is the night to make that fantasy come true, hm?"
"Yes - yes, definitely."
Hands sped into motion, and soon they stood naked, facing each other. He stroked her belly and cupped a breast, and she gripped his warm cock in her hand. He sighed, and she smiled - then, she led him around to the front of the desk, facing the empty classroom.
She eased him up onto the edge of the desk, then turned to face the room.
"For a special treat today, class, I've brought my lover for Show and Tell. First, I'm going to show you just how much I like sucking his cock."
She turned to face him, knelt, and took the head of his cock into her mouth. As she worked the tip of her tongue up and down the sensitive skin just below it, she felt the head swell against her tongue. He leaned back slightly, braced himself with his arms, and surrendered to her lips.
She toyed with him for several minutes, then eased back and turned her head to the side.
"You can see how much he likes it - can everyone see just how big he is now? I could do this for hours," she continued, flicking the tip of her tongue across his tip. "I can tell when he's about to come, so I just back off and let him calm down for a minute or two. Then, I get him all excited again."
She circled the base with her thumb and forefinger, took a deep breath, and swallowed him whole, sticking out her tongue to make more room and lick the top of his scrotum. He gasped and balled his hands into fists, but otherwise remained stock-still as she gulped at his slick flesh.
"He really, REALLY likes that, too," she laughed huskily as she looked back over her shoulder. "I have to be careful with that, because he sometimes catches me by surprise and squirts right down my throat. Not that that's a bad thing, of course - I love it - but sometimes I want to go a little longer than that."
After a few more minutes of fellatio, he was breathing hard and sweating. She stood up to face him, then sat beside him on the edge of the desk. Holding his pulsing cock in one hand, she tossed back her hair and smiled.
"All this is very nice, but it really just leads up to the main event. See how wet I've gotten?"
She opened her thighs and trailed a fingertip along her damp pussy lips, opening them like a warm flower.
"Now, it's time for the real action. I like to be fucked, and fucked hard, and then fucked some more."
He stepped in front of her, lining himself up. She rocked back and held herself up with her hands behind her, crossed her ankles behind his head, and drew him in. He braced himself against the desk and eased inside her, guided by her fingertips. As his head forced her lips apart, she shuddered.
"Oh, yes...," she murmured. "That's what I want - give me all of it!"
He took the first few strokes slowly as she addressed the classroom.
"I love the feel of him inside me - first, just a little bit, and then later on I like him balls-deep in me, stretching me with that big cock he's got. I get so wet I make a real mess, but I don't care."
He picked up the pace, and she moved her legs down around his waist, digging in her heels and spurring him on. He slammed into her hard enough to rattle the drawers in the desk, gritting his teeth as he buried himself to the bone. She was gasping for breath, snapping her head from side to side, squeezing him with her thighs and pussy in time with his thrusts.
"And - class - this is where I - I - "
Her stuttered speech dissolved into an animal howl, and she launched herself up off the desk and into his arms. Her fingernails ripped angry welts down his back as they writhed together, and he squeezed the breath completely out of her when he erupted in the middle of her orgasm. She hung limply in his arms, panting hoarsely into the nape of his neck, and he shivered from head to toe like a wire in a high wind. After a moment, she looked over his shoulder at the classroom.
"This is where I come. I like to come hard, and I almost awlays howl just like that."
She felt a rumbling chuckle in his chest, and she nipped him on the earlobe.
"You think this is funny?"
"Not at all," he laughed. "I just hadn't realized how well-developed this little fantasy of yours would turn out to be."
She eased back and supported herself with locked elbows, searching his face for any sign of mockery. Seeing none, she smiled and traced idle patterns on his chest with a fingertip. He smiled down at her, then reached around to snag a pack strap with a toe and drag his bag within reach. He hauled it up onto the desk, fished out a towel, and handed her one end as he eased out of her.
After wiping up, he sat on the desk beside her while the sweat cooled on them both. After a few minutes of rest, her hand strayed between his legs. He responded quickly, looking forward to another round.
He grinned, swept the bag off the desk, and climbed on top of it. The desk was wider than a standard desk - another monument to excess like the all-night dim lighting, he supposed.
"What are you doing?"
"Mount up, cowgirl," he said as he lay down across the width of the desk, head facing the room. He caught the chair with a foot and rolled it into position to support his legs, then grabbed the base of his cock and stuck it straight up like a flagpole. "Show 'em what you've really got!"
