“Ah, Mr. Troman–can’t say I was expecting you to show up for my office hours this semester,” Professor Porter said, “I’m afraid it’s a bit too late to do much good, really, as far as your grade will be concerned.”

The older man only half suppressed the grin on his face as the young football player sat down in the chair in his office. They always came, eventually, but Porter was well known for his unrelenting distaste for athleticism. College, in his opinion, was for study–there was quite simply no reason for a school to possess a sports team. The coaches had learned, over the years, that not even pressure from the dean could get Porter to give their athletes a passing grade, and so they urged them to avoid his classes. Trent Troman, fraternity bro and football player, hadn’t followed his coach’s advice, but he didn’t seem to be sweating it much. “Look, Mr. Porter,” he said, “I’m just going to give it to you straight. I’m going to pass this class, and you’re going to give me at least a B, or I can tell you, you aren’t going to enjoy what happens next.”

Porter chuckled–he had to admit, the young man was…confident. “First of all, I’d suggest you refrain from threatening people, going forward, either other teachers or your future managers in whatever retail business you find yourself when you leave here. Second, you have repeatedly skipped my class, turned in your assignments late or not at all, and what I did receive was of such a poor quality that it’s almost like you wanted the F I plan on giving you after your final in a few days. I know you haven’t been here very long, but there’s nothing this school can do to me, to keep me from my decision. Now, I have other students who could actually use my counsel, so feel free to show yourself o–”

The last syllable didn’t actually manage to make it’s way out of his mouth, because something else appeared in it. He felt it with his tongue–it was some strange rubber ball, and he could feel straps running around his face and over the top of his head. He reached up and felt them, crying for help as best he could through the gag, Trent just watching him like nothing strange had happened at all. His hands followed the straps back, to where they latched, and he found a small padlock there–with a light jingle, Trent displayed a key in his hand, and then pocketed it. Porter just glared at him for a moment, unable to believe what had happened, and then went to get up from his chair…but in an instant, something…pushed him back into the chair, and when he went to get up again, he found his wrists and ankles had been bound to the arm rests and feet of the chair with leather straps. Calmly, Trent stood up, shut the office door, and locked it.

“Now professor, I think…you need some time to think this over again,” Trent said, as he fished through Porter’s pockets, found his keys and phone, and stepped back. “I’ll be back around…say midnight, and see if you’re a bit more…comfortable with my offer then.”

Porter protested through the gag in his mouth, but Trent turned out the lights and left the office,  locking it behind him, abandoning the professor in the small room. It was nearly five, and thankfully he didn’t have a class he’d be missing–or at least then, someone would have found him, tied up in his own office! For a while, he kept trying to make enough noise to attract someone’s attention, but as the evening wore on, the building emptied out, leaving him alone, without even a janitor to find him. All he could do, in the dark, was stare at the clock, and watch the minutes tick by until it finally reached midnight.

However, like usual, Trent was late, arriving a quarter after. He unlocked the door, turned on the light, and took his seat again. “Now, since you’re being stubborn, I’ll revise my offer. Give me an A, and I’ll let you go, and we can forget this ever happened.”

Porter didn’t know how the young athlete had managed to do this, but even after all of those hours stuck in his chair, his fear still hadn’t surpassed his principles. But he did want the gag removed, that much he did know. So he decided the best technique would be to lie. He gave a nod, and as fast as it had appeared, the gag was gone, and he could breathe and speak again. “Fine–whatever you want, just…get me out of this shit.”

Trent chuckled, and the rest of the bonds were removed, allowing him to stand up, feeling blood rush to his limbs, which had fallen asleep in that position. But he could feel…something else, which didn’t feel quite right at all. He hefted up his gut and felt his crotch, where he discovered…something was on his cock. “I call that a little insurance policy. Give me my A, and then that comes off. Now, I’m late for a party, so I’d best be on my way. See you in class, professor.”

Porter waited until Trent was out of the office, before dropping his slacks and looking at what was around his cock–a solid steel chastity device. He fiddled with it, trying to figure out how to get it to work, but the thing seemed…completely solid, and he had no clue how to even begin extracting himself without simply pulling his cock off. That young bastard had this well planned, apparently–still, one thing Trent and his strange powers couldn’t account for was plain old stubbornness, as he discovered a few weeks later, when he received his grade report, with a bright red F under Porter’s name, among the rest of his A’s. That was new–and Trent nearly hurled his laptop across the room in rage. Still, he would have the last laugh, he’d make sure of that, oh, he would be laughing for a long time after this.
