I suppose it's in the nature of a man to remember the exact moments when a choice branches his life in a different direction. That night I spent with Cole, my T.A.—that was one of those nights. That was one of those choices I bear the responsibility for. We were grading papers in my study. There was a silence between us, one that I didn't find particularly uncomfortable. I would occasionally look over to the boy—he's a jockish sort, toned for his age and youthful good looks—and see his focused expression honed in on the stack of papers in his hand. I would've never guessed there was anything else on his mind. It wasn't until he finished that I knew how heavy the silence had been. He stood up and walked over to me, presenting his stack of graded tests with a slightly quivering hand. Because I was seated and he was standing, I became aware of another thing that he presented to me; at my eye level, I could see the bulge of his tight suit trousers. He was tenting. even under all those layers. It must've ached. Cole reached out to me, tugging my sleeve between needy fingers. This was one of those life-altering moments where I chose poorly. He guided me to his crotch. I unzipped the fly, and allowed his hard cock to flop free. He was thick, far thicker than I expected the college freshman to be, and it was a struggle to fit it entirely into my mouth. But that didn't stop me, of course. It didn't stop me from buttoning my own slacks, either. Because I'm a good teacher. A great one, if you ask anyone who's ever met me. Clearly this blowjob was something my student needed, and I was more than happy to show Cole the proper form one should take when swallowing as big of a cock as his. And he was always such a good student. It wasn't long until Cole was down on his knees, trying desperately to swallow my dick whole. He looked so cute and innocent, kneeling before me with his head bowed. His eyes were fixed upon my cock, glazed with pleasure and concentration. We had long crossed the threshold of hesitance. We were now both fully committed to the act, and were aware of nothing else around us. I pushed Cole down against the leather stool. I could smell him, the scent of sweat and sex and excitement and youth. I guided my cock between his cheeks, and rubbed it against his hole, teasing him. He moaned—a soft little whimper that sent shivers through my body. I don't know if it's just because I had lusted after him for so long and didn't realize it, or if it was just a natural reaction to his body, but a certain madness overtook me. I fucked that boy with a speed and ferocity I had not given anyone or anything in a very, very long time. I pounded him into submission. I wanted to hear him cry out my name. I wanted to watch his eyes roll back and his hips jerk up against my thrusts. I wanted to make him mine. And it was that madness, and speed, and sweet tightness that his hole naturally secured my dick with that eventually sent me over the edge. I pulled out as I felt my release flush through my loins. With the vision of his perfect bubble butt and bare back splayed out in front of me, I jerked myself off till the constriction of my orgasm spewed all over him. I marked him with my seed, a veritable pollock painting of cum all across his broad backside. The come down from the orgasm was harsh. I had just fucked my teacher's aide, and I think we both knew it wasn't going to be the last time we'd do this. I fit into him entirely too well, and I wanted—needed—him again, and again. For as many papers as needed to be graded, for as many semesters as I could keep him within arm's length.
