Sex in the gym with a student pt1

This is my first post and I'm going to tell you what happened to me at work. I am a weightlifting coach in a fairly large gym with several floors, I'm half-convinced that there's always a fetish between students and teachers. As for myself, I'm dark-skinned, normal build, dark eyes, 1.63 meters tall, a common type, let's say. My job consists of being on the weightlifting floor guiding people and doing routines, one Tuesday was working as usual when a girl around almost 30 years old, thin, 1.70 meters tall, with a rocker haircut and good vibes, came up to me asking about what I could or couldn't do while her daughter was in another room doing something else. I commented on top of that what we could do in an hour while waiting for her daughter and she left. Again on Thursday, she approached with the intention of starting, began guiding her a bit while also being with the rest of the people, ended the training session because I had to go get her daughter, said goodbye and left, all normal. Later, I see that I got a friend request on Instagram and it was her, I'm half-surprised because I never told her my last name so she could look me up or anything about it, besides always liking being located at work, as you know... You eat where you crap. She sends me a direct message saying I found you!!! and we start talking, all good. I leave work late evening and keep chatting, well, the chat goes back and forth and I was already starting to throw some punches.I: What do you do?
She: Eating, and you? I made a compote haha! I'm an old woman in a body of...
I: Do you decide?
She: You should pay attention! (with the emoji covering the mouth)
I: We could, I didn't see you so bad at the gym eh!Then the conversation went back to normal, I posted a story on Instagram and she put a heart on it (they saw that now Instagram allows you to put a little heart on it? okay, that's it) When I saw that, I wrote to her againI: What's up?
She: Lying down on my ass already, and you?
I: (Inside, I was dying to tell her 'Check out that bum' but well, work comes first so I said instead); I'm not lying down but I am in shorts, to be more comfortable
She: Let's see how the teacher is comfortable!
I: I sent a photo of myself in leather and with short, it wasn't showing much but my half-hot bulge was noticeable just thinking about that ass I saw earlier today.
She: Bebeee, I want more!
I: I also want a photo now! That's fair for both of us
She: She sends me a photo of herself in thong, truly beautiful ass,
I: Now I also want more!
She: Well but I'm going to sleep because tomorrow I have an early school dayThe next day he writes to me again, asks what I was doing and I send him a photo of myself sitting with a short on and the background of the muscle floor.She: Don't you feel cold in that short? I can warm you up!
I: For now, I'm fine but a little more heat wouldn't hurt
She: What are you doing later?
I: I'll be working until 9pm, if you want to come and train, come on
She: And what if I want to see you outside the gym?
I: If you want, we can meet at another floor...
She: How would that be???
I: Ah! You come and before going up to the weightlifting floor, send me a message and I'll tell you where to go...Pass the time and tell me you were about to come up, I just didn't have that many people on the floor so I could escape for a bit from my place and I'm going to some bathrooms that are on another floor. Send him a message saying ''Wait for me on the 3rd floorI go up the stairs and when I open it, I see her. She was wearing black transparent leggings and a white thong. Clearly, I stared at her from top to bottom and said 'what a beautiful thong you have.' When I approach, I go straight for kissing her. We get excited and then she says...Where are you taking me?I grabbed her hand and led her to the bathroom, all the lights were turned off so it was pitch black. I pinched my dick as soon as we passed through the door and I started wanking in her pussy, she was really wet and I had a boner! I basically wanted to jerk off at work. I took down my pants, sat on the toilet, and the little girl sat on top of my cock, moaning like crazy and grabbing my neck telling me I felt like I came and finishedI was already there with the cock almost about to explode, between adrenaline from the moment and other things, imagine it, I took her out of there and started banging against the door, the little cowgirl didn't stop moaning, I grabbed her mouth and she started sucking my fingers and with her hand touching my balls while giving me a back massage. We stayed for a bit until I saw she was about to come again, I said '¡Vamos, vámonos!'Okay I have to go down to keep workingI lifted my short, we greeted each other with a beautiful tongue slap and she wasn't letting go of the cock with her hand, while I kept touching that pussy and felt it all wet. That afternoon I went down and kept working with an adrenaline that lasted at least another hour more, sent her a message saying I loved it and wanted to do it again. If you want to know how it goes on and see a couple of photos leave a couple of points and I'll tell you more! PD: I'm new, literally, and don't know how to put the post so that everyone can see it without needing to register, if someone wants to give me a hand, thank you!
