The Professor demonstrates oral sex to the class

"Another excellent tool in foreplay is oral sex. You should gently suck and lick the clit and surrounding area. Pay attention to how she reacts. If it seems like it's really working out for her, don't change a thing and keep doing exactly what you're doing. I will now demonstrate."

And with that, my professor dove between my legs and began eating me out while the class watched and took notes.

He was doing an amazing job, and everyone in the class could clearly hear my moans as I clamped my legs around his head, my toes curling in pleasure. I had two more of those aborted orgasms before he was done with me.

"If you've done your job well enough, your partner is now sufficiently turned on for penetration" my professor explained to class as he pulled out his dick. And since I'd never seen my professor's actual penis, the simulation was using the pornstars ridiculously large cock. It had to be as thick as my wrist; there was no way it would fit inside me! Of course, it didn't have to. It had fit into the female pornstar whose sensations were being recorded and played back on my brain.

The professor helped me to spin around on the table so that he wouldn't block the class's view of my body while he fucked me. He held my legs up in the air in a V shape, and my head dangled off the end of the table, staring upside-down at the students diligently observing me. Most of them had erections and many were visibly jerking off while they watched my professor sink his massive cock into my pussy. I screamed in a mixture of pleasure and pain as his dick split me in two. As he slowly pumped in and out of me, the pain lessened and the pleasure grew as I got more used to the sensation and as I grew more aroused by all the men watching me. But just as I grew accustomed to him inside me, he began to pick up his pace, quickly reaching what can only be described as "jackhammering". He was pulling almost all the way out of me and then slamming in as hard and fast as he could. My eyes rolled back into my head and my moan became a constant oscillating note as sensations threatened to blot out my consciousness, leaving me as nothing but a vessel through which pleasure flowed. There were no longer any other thoughts within my mind and I lost all sense of time.

When I regained my faculties, the first thing I saw was his massive cock dangling right in front of my face. I guess the simulation had continued without me and I was now kneeling on the ground in front of the professor, apparently about to give him a blowjob. I watched as I reached out and wrapped both of my hands around his shaft. My fingers could scarcely make it all the way around as they began to stroke up and down. I then inserted his cock as best as I could into his mouth and began to give the best blowjob I had ever given. This was a pretty low bar as I hadn't given any, but it was still a stellar blowjob as it wasn't me driving the reigns, it was the pornstar whose sensations had been recorded for my enjoyment.

I paid attention to the technique I was using as my hands worked his shaft and my tongue caressed his glans. I wondered absently if this counted as studying to earn me more orgasms. It probably did. Studying was pretty loosely defined and I was definitely learning something right now. Even if it was how to suck dick like a pornstar and nothing to do with math at all.

It wasn't long before he pulled out, and as is apparently required by "The Laws Of Pornography" or something, he jerked himself off onto my face as I waited with my mouth open and tongue out. And with absolutely uncanny timing I reached the end of my 1 hour of teasing just as his salty cum splashed across my tongue. The orgasm ripped through me without warning and I cried out in pleasure "OHHhhHH FUuuUUCcK". It was as if I had cum from the taste of his cum alone.

When I opened my eyes, the simulation was gone and I was back in my room feeling very sweaty in my bed. My roommate Steve stood over me with a glass of water and said knowingly "Hey"
