This happened a couple of weeks ago, but I didn't have time to write it down up until now.

About a month ago, after embarking on a search for an online Mistress on Reddit, I was contacted by one who had read my first story here. I won't get into everything that has happened so far, but suffice to say that we immediately clicked and have been in constant communication since. She tasked me with writing a story about one of the orders she gave me.

I go to the gym regularly and I am currently trying to do a lot of cardio in order to get ready for the summer. She knows that, of course, and it’s not rare for us to sext while I’m working out. She loves imagining and reading about the effects she has on my body, especially while I’m in situations that make it hard to hide (pun intended), or when I’m unable to act on the needs she activates in me. I believe this is what made her come up with the following task in the first place. This is the actual message that she sent me:

Remember when I was teasing you while you were on the treadmill? Next time I want you to go to the restroom and touch yourself. Then stop and get back back to your work out. If you do a good job you can then make yourself cum in the restroom.

So, here is what happened.

I went to the gym three days after receiving that text. Three days that I spent replaying her words in my head again and again, getting painfully hard every time my mind dared to wander.

So, when I arrived at the gym and went to the locker room to get changed, I could already feel myself growing hard in anticipation. Now I should say that the male locker room is really no place where I would want to be seen with a boner, so I put on my headphones and tried to distract myself. Thankfully, it worked well enough to allow me to change into my sport clothing without too obvious a bulge.

Choosing a treadmill, I decided on the one in the farthest away corner from the mirrors and others. The first 30 minutes of running went fairly well, all things considered. I ran at about 160 beats per minute which is what I usually aim for. The music did a decent enough job keeping my mind busy, so while I was semi-hard the whole time, at least it didn't hinder my movements.

Then the time came for my break (and my task). I paused the program, left my towel and water bottle on the machine, and went to the bathroom as she had instructed. I already knew that I wanted to read something while stroking, and I knew exactly what. In the previous days, during a particularly hot sexting session with my mistress, she had written me the story of one of the hottest sexual experiences she’s ever had. It involved her torturing her FWB by teasing and denying him until he was begging her to rim and peg him. I had come to it before - and just thinking about it now makes me hard again. The mere act of scrolling up to it in our chat had me fully erect within seconds. I guess I stayed in the stall for a maximum of 5 minutes, and that was only because I forced myself to go for really slow strokes. While I didn't intend to do so, I ended up edging myself over and over, since I couldn't help but pick up the pace from time to time. Of course I always stopped before the point of non-return, as to not disobey her order…

Throughout all this, I could still hear the sounds of the gym right outside the door, and was quite conscious of it. Luckily enough, no one tried to enter while I was in there. Eventually, it got to a point where I was so desperate that even the slightest stimulation could have made me lose all control. I had to spend a few minutes basically meditating to calm down at least a little bit.

As I went back to my treadmill, I regretted not bringing my towel with me since I could have held it in front of my pants on the way back to hide my very visible bulge. Instead, I just kind of shuffled there and hoped that it wasn't too obvious. I continued running and, as I had observed earlier, the horniness boosted my performance. In the second half hour I went much faster and with a higher bpm (about 175), without feeling more exhaustion. My mind kept wandering, not really feeling my body, and I was completely in the zone, only thinking about my mistress, fucking and cumming. I was so focused on passing the time that I didn't really sense what was happening around me. Thinking back to it now, I am sure that I was hard through it all, but surprisingly it didn't hinder my running severely.

Once I was done I wanted to get to the changing room asap, and nearly tripped on the way over since my legs didn't work correctly anymore. That is common for me after running on a treadmill, but normally I take my time to get back to walking on "normal ground". This time around I obviously had better things to do. I hope nobody saw that I had a raging erection on my way back, but at least this time around I was able to use the towel to hide it.

When I was back in the bathroom (fortunately it was not occupied, I don't think I could have waited) I nearly ripped my underwear while pulling it down, and noticed that it was drenched in precum. I once again scrolled back to our previous chats, this time to a session we had while/ after my mistress was in the gym. I grabbed my cock and started moving my hand up and down, but I nearly didn't have to. I don't know if it was because of the prolonged teasing and denial, or because my dick was rubbing against my underwear during the work out, but I only lasted for a few hard strokes. I came so hard I even ended up hitting my head on the wall throwing it back. I really couldn't say whether I passed out for a second or not, but my mind definitely shut down from the explosive release of my pent up lust. I had to clean off the wall since I did not think about where I was shooting, and I left 3 big streaks of cum down the wall right in front of me. Afterwards I was so spent I could barely move, but somehow I managed to drag myself back home. I still like to think back to it and really look forward to all the tasks, rules and everything else that awaits in the future with my mistress.

My story might be finished now, but my post is not complete just yet. She tasked me with writing a bit more about our situation in general. We came across each other randomly, and we both count ourselves extremely lucky. She's from Italy, I'm from Germany, and we both have a busy "real life" that doesn't allow us to chat as much as we might like, sometimes even with days with no communication at all. But we made that part of our arrangement. We don't expect each other to be available constantly and so far everything has worked out great for us! Of course the thought of being a sub 24/7 has invaded my fantasies before, but one has to know what is realistic and what should remain a fantasy. There is nothing wrong with that. Honestly I have never met anyone who managed to turn me on this much simply by chatting, and the more we talk the more our chemistry becomes evident. We’re now at a point where just thinking about the other person has me rock hard and her wet within seconds.

I can't count how many times I’ve already come to our chat, or simply thinking about it, and from what she told me it's not much different for her. Reading my descriptions, stories and the like regularly makes her wet and thinking about that turns me on in turn, which leads to a devilish spiral of lust that we both hope not to be swallowed by. I am now fully submitted to my mistress, I have gifted my body and mind to her, and only wish to serve as her sex toy. I dream about being used, abused, tortured and trained by her and crave any orders, rules or rewards she shall give me. I am hers to do everything she wants with.
