"Oh, shit, Pete. You have me filled." I was flabbergasted. One of my students had turned the tables on me and had me skewered and pinned to the floor.
"And you're starting to love it, aren't you?" Pete responded with a laugh. "It's that big black cock that's in you, Professor. The one you admired so much. Admit it, you love having me inside you. I've seen you giving me that look in class. You thought it was a desire to top me. But it was a desire to be fucked by me. And that was even before you saw what I have to give you, wasn't it? Admit it."
"Yes, yes," I whimpered quietly. "I do love the idea of you being inside me. Take me. Pump me with that big black cock of yours." And he did then, giving it go me in both long and short strokes.
At length. "I'm about to cum, Professor. Do you want me to shoot inside you or do you want me to withdraw?"
"Inside, inside, please, Pete. I'd forgotten how this had felt." I had forgotten how much I'd grown to love my own professor's dick inside me. He'd had one of those slightly bent dicks that didn't look like much when he started but that grew in length and thickness once inside me, so I could feel it filling me, possessing me. "And then stay inside me. I want to feel you contracting inside me."
With a grunt and a groan from Pete and an exclamation of ecstasy from me, Pete shot his load inside me. As requested, he continued lying there on top of me, his dick buried in me, as he regained control of his breath.
"I don't plan on contracting inside you for a while, Professor. One of my talents is stamina. Something a football player's gotta have. All you have to do is give me some lip work, and I'll be ready to go again."
"No, Once was more than enough, Pete. This isn't . . ." Pete had rolled us to where we were on our sides, him behind me, and his dick still inside me. The arm that was under me wrapped around so that he could get to, first, my nipples and then down my body to my dick. He had locked his lips on mine with his mouth, and his other hand lifted my leg to give his dick full access to my hole. My desire leaped to life as he pumped me, and his desire started to build again as my kiss became passionate. In no time his cock was growing again and he was side splitting me deeply to a second, more prodigious ejaculation.
He pulled out of me after that and kissed down my chest and belly, his silky black hair swirling around on my torso. Then he untied my hands and lay beside me on the carpet.
"That was an outstanding fuck, Professor," he whispered into my ear. "I've been wanting to do that since the first day I walked into your class. And you want to know a little secret?"
"What is your little secret, Pete?" I asked in a flat voice.
"It was all a ruse. The plagiarized paper was only a ploy to get my dick inside you. And you're glad I got my dick inside you, aren't you, Professor?"
"Yes, Pete," I sighed. And I was glad, but now I had to become the professor again. "I'm very glad you did that, but we haven't really moved one step beyond our agreement. There's still a plagiarized paper and an agreement."
