I have shared some of this before and a few people have messaged asking for more details. So, here's some of the same post as before as a recap, but I've added even more recent stuff at end!
For my (F45) job, I'm partially responsible for our internship program. Usually 3-4 college students, most often seniors, who join us for a semester. I don't work with them directly but instead figure out what team that should be with, have weekly check ins, and manage the administrative side.

Except with this most recent group of interns. There's one, we can call him Ryan, who really stood out from the start. Quite tall, reasonably fit, good dresser, very smart (he skipped two years in school so he's a junior at 19), and he knows it. Very confident, which I find incredibly attractive.

After about a month, we're having his check in and I ask about how things are, things he likes about working with us, areas where he has questions, all that. And he responds to the "things like likes" by just saying flat out "Well, having a hot supervisor is a perk." I went RED. All the training I had to handle comments like that just left me. He just smirked and continued like nothing happened. We finish the meeting and I am sopping wet.

Next week, meeting again. Same basic questions. "Things to improve?" "Yea, you shouldn't do all those buttons. Ruins the view." Same reaction. The next morning, I'm getting ready to go to work, getting dressed...and I remember it. And decide to leave one more button than usual open. I'm bringing some documents to someone on his team and he notices. Doesn't say anything but just nods. I melted. I was counting the minutes for our next meeting. Changed the schedule - last thing of the day.

He comes in, we start as usual. And he just looks at me, mid conversation - "why not another button?" So I did. And he just smirked. He got up and locked my door. Told me to stand up, to take it off for him. I did. I just felt so drawn to him. The confidence, the demeanor...I couldn't help it. After a minute, I'm on my knees. I sucked him, right there. Didn't say a word. He was bigger than I'm used to but I think I did alright. I hadn't swallowed in ages, I never do with my husband. But with him, I did. It has escalated since then. We meet twice a week now, usually in my office, sometimes one of our cars.

We have progressed to having sex, not just blowjobs. For example, we hook up a couple times a week now. Usually, we have used either my office - he loves bending me over my desk - or we use my car. He loves spanking me, pulling my hair, and calling me a slut and a bad girl. Once, I was leading a lunch meeting at work. I took him with me to pick up the catering. On the way, we stopped at an empty parking lot. I sucked him off there, in the car. It felt so dirty and degrading, it was like something I might have done when I was younger but doing it now just seemed so wild! I know it really isn't, but it definitely felt it, especially going back to work after and tasting him on my mouth still.

I do things with him I wouldn't with my husband and he is far more dominant and degrading than I am used to. Physicality, confidence, and comments - including degradation - are all just so good with him. He has started giving me more ideas of what to wear, never anything to inappropriate but just a bit of risky. It's intense and exhilarating and I can't stop.

We might be escalating things even further now, too. We message each other a bit, using a different app, and he has mentioned wanting to see me this weekend. That I should sneak out to see him. He mentioned it again yesterday, while I was sucking him. He wants me to come over to his apartment so we can fuck there. I told him I shouldn't and that it's too risky. So then when I was sucking him more, he just held my house down. And told me again that I should come over. And that he would let go when I agreed. It was such an incredibly hot and powerless feeling and I just couldn't stop myself, I gave him a thumbs up. So now I'm making up an excuse to disappear on Saturday for a few hours...
