TL;DR I was dirty chatting online. One chat partner turned out to be a student at my Uni. We kept dirty chatting to each other, eventually revealed identities and she walked into my office and became my little slut for half an hour.

So, I've always had what you could call a slut fetish. I love slutty girls (yes, I mean women, but I'm going to say girls). I love to help girls release their inner slut. I love to hear how "good girls" secretly would love to be slutty, or they've had slutty experiences. The word "slut" itself turns me on. I love for my own GFs to act slutty, even with other guys.

Anyway, as a new professor--and married to a wife who became religious and shut down any slutty expectations--I would sometimes play online. Text chat rooms or on video (Omegle and the like). I was in a slut-related room (surprise) and started chatting with this one girl. She had a total slut fantasy, we got each other off. We chatted again, and it came out that she was a college student, and I told her I was a professor. Then we said what state... same. Then we joked about how it would be funny if it was the same Uni. We both described the Uni without too much detail and, yes, it turns out that it was the same institution. But, we didn't reveal identity... yet.

We continued to chat for a while. She showed me where she had posted some nudes (without face) and she helped me get off to them. We were both exploring the whole prof/student fantasy. She had a bf who like to fantasize about her being a slut and randomly fucking some guy someday, but she hadn't yet done it. We gave little bits of info to each other and I had narrowed it down to about 3 students, and the same for her. So, we were chatting one day, and she told me where she was on campus. I walked by there and our eyes met, and we both instantly knew. (She was not a student I'd ever had in class). She gave me a sly smile and held her gaze. The adrenaline of that moment was insane.

I went back to my office and we kept chatting about what our fantasy would be if she walked into my office. And then I dared her to do it. I'm sure you can imagine all the feelings. Lust. Adrenaline. Fear about my job and marriage if anyone found out. But, yeah, lust won out. Here's how it went.

I closed my office door and closed the blinds and waited. About 20 minutes later she walks in, closes the door and locks it behind her. She was in a fairly conservative white button up blouse and relatively short grey skirt. She sits in my guest chair and waits (she was a submissive for sure). Without a word I walk behind her and put my hands on her shoulders. Then I slide them down the front of her blouse to grab her massive (yes, massive) breasts. She moans. I pinch her nipples. She moans again. I whisper in her ear "Is this what you wanted?" She nods submissively. I pull her blouse open and continue to play with her breasts. Then I walk in front of her. She knows what to do: she unzips me, pulls out my cock, and immediately puts her mouth on my cock. After I'm fully hard, I end up tit-fucking her until I cum all over those massive breasts. And, she licks it all up by bringing her tits up to her mouth. Then I return the favor by fingering her wet, dripping, pantiless pussy until she cums for me. She left without us exchanging any more words than what I've written above.

It was obviously one of the hottest sexual experiences I've had. Planned, but spontaneous. Strangers, but not strangers.

I'm happy to chat with anyone about Prof/student fantasies, or other things.
