Jack slid quietly into Aster's office and closed the door behind him.
"What're you still doing here, Jack?" Aster inquired, not looking up from his work. "It's nine o'clock on a Friday. Everyone's gone home."
Jack came forward shyly, placing his books on a nearby couch. "I wanted to see you."
"After hours?" Aster glanced up, arching an eyebrow. "What could you possibly have in mind?"
Jack blushed. He'd been caught.
"Unfortunately, I can't indulge you today." Aster returned his gaze to his work. "I've got a lot of essays to mark by Monday."
Jack flushed with indignance. He'd waited hours for everyone else to go home, students, professors, even the janitors. He'd waited to make sure it was just him and Aster at Pine. He wasn't going to be so easily deterred.
He came forward to Aster's left side, and placed a hand on Aster's large arm. "Please," he wheedled, running it down Aster's muscles, rippling under his shirt.
"Jack, not today," Aster insisted.
Still undeterred, Jack went for the coup de grace. He lifted Aster's left hand from its position on the desk, and placed it on his bulge. "I'm begging you," he said in a low, throaty voice.
Aster finished the sentence he was writing, and laid down his pen slowly. Suddenly, so fast Jack barely registered it, Aster grabbed him and pulled him down on his lap, with Jack's back pressed firmly against Aster's chest.
"You little tease," Aster growled into Jack's ear. The professor's right hand crept around Jack's body, down to Jack's crotch and grabbed him there, eliciting a soft gasp from Jack. Aster's left hand crept under the hem of Jack's T-shirt, creeping over his bare stomach and then chest, lifting his shirt. Jack gasped again as the older man's left hand found his right nipple and squeezed – hard.
"Is this what you want?" Aster's right hand undid Jack's belt buckle and pants button and slid under the pants' waist. Jack moaned as he felt Aster grasp him firmly underneath his pants.
"Oh, Aster," he breathed as Aster's hands continued their magic, the left one pinching and teasing his nipple, the right one stroking him.
He moaned again and again as the pleasure built. Finally, he begged, "Fuck me!"
He felt the low chuckle ripple through Aster's body. "You asked for it."
Suddenly, Aster's left hand was tugging Jack's T-shirt over his head, and Aster's right hand was pushing Jack's jeans to the ground. Within seconds, Jack sat naked on Aster's firm erection, bulging through his pants.
Aster quickly unzipped his fly and pulled his member out between the teeth, and slowly, carefully inserted it into Jack.
Jack groaned as he felt Aster fill him. Slowly, Aster began to pump in and out.
The rhythm picked up and Jack bounced on Aster's lap, crying out, gasping and moaning, as his professor fucked him. Aster's left arm wrapped around his chest, holding Jack's body close to Aster's chest, his fingers continuing to toy with Jack's sensitive right nipple.
"Oh, my god!" Jack cried as Aster pounded him up and down. The grunts he heard issuing from the professor's mouth told him Aster felt the same. Jack reached down and grasped himself, furiously pumping himself.
"I'm – I'm close!" he gasped, as he felt the heat pool in his stomach. Aster didn't slow, and seconds later Jack cried out, spilling himself onto the floor in front of Aster's desk chair. Moments later, Aster grunted, and Jack felt heat rush into him from Aster, warm and sticky. Aster sat back against the back of his chair, eyes closing.
They sat together in Aster's desk chair, panting and sweaty. Jack felt Aster wilting inside him, but made no move to clamber off the professor's cock – he wasn't sure his legs would work anyway.
"Tell me," Jack panted once he'd caught his breath, "why is it that whenever I'm in your office, I end up naked while you remain fully clothed? Seems unfair to me."
For a moment, Aster didn't respond. Then suddenly his left arm snaked back around Jack's chest, and Jack yelped as his fingers squeezed his right nipple painfully hard.
"Are you saying I'm no good clothed? You didn't get pleasure from me while I was clothed?"
"No, but – " Jack tried to protest, but Aster was moving beneath him. Beginning to move up and down again. Whatever thoughts Jack had been thinking were chased out of his head as he moaned, realizing that Aster was growing rigid inside him again.
"Am I going to have to teach you a lesson again?" Aster picked up the pace again, and soon Jack was squealing and moaning, bouncing up and down again on Aster's cock, still sitting in his lap.
Jack's hand reached for his own member, but Aster batted it away. "No touching," Aster growled into Jack's ear. "I'm going to show you how good I am – I'm going to make you scream without you even touching yourself."
Both of Aster's arms wrapped around Jack's naked chest, holding him tightly to Aster as he bounced his student up and down on his member. Jack's nipples were pinched and abused, and Jack began to feel the heat pool in his stomach again.
"I'm close," Jack shouted, "I'm close!"
Aster sped up in response, and Jack screamed as he finished again, shooting onto the floor.
Aster stilled momentarily, then whispered in Jack's ear, "It's my turn." He resumed his pounding rhythm, and Jack moaned and mewled as his professor fucked him soft.
Finally, Aster grunted, and Jack felt him pour himself into Jack once more. Aster's arms released Jack, and the student slid off Aster's cock and lap, his legs turned to jelly, to sit on the floor by Aster.
"That was – that was…"
"I know." Aster grinned at him mischievously. His cock wilted in front of Jack, still poking through his fly – he hadn't bothered to put it back in.
"I think I need a minute."
"Take all you need," Aster said, picking up his pen again. "But then leave me to work. As I said, I've got a lot to do."
It took Jack fifteen minutes to find the strength to put his clothes back on and get to his feet. As he reached the office door, he looked back. Aster was once again engrossed in his work, murmuring to himself as he wrote on students' papers.
Should I tell him his cock is still poking through his zipper? Jack wondered. He shrugged. Nah, it'll be funny when he finds out. He slipped quietly out the door and left an indecent Aster to do his work.
