I am sitting on the edge of the training area.

From here I can watch Gabi without her knowing. I think to myself then lecture myself about being a creep. But what is the harm in looking?

My word - Alex - get yourself together. I am still so angry with her for some reason - well - over all of this self-defense nonsense and the fact that I had to give in and actually come here to let Bella do a class with her. I should not be lusting after Gabi like this. Women do not usually have this effect on me where I can't even control my own thoughts, so what is it about Gabi that is so different?

She is on the mat showing Bella some stretches and the way her body moves is making me uncomfortably turned on. I shift in my seat and try and drag my eyes onto other things in the room.

I force myself to look around, taking in all the details. There are boxing bags, a rack of gloves, a rack of weights in the back, some heavy ropes, weight bags, and a climbing rack that doubles as a lifting bar. I look around slowly and find that I really like the gym. It is laid out with each section set up perfectly for that exercise.

Half the gym is set up with open areas for her classes and the other half of the gym is set up with gym equipment where people can work out on their own. There are even treadmills and climbing stairs for cardio sessions.

On the walls near the reception desk are some photos of the classes she has done, and the kids are all smiling in the pictures. There are some photos of martial arts competitions she has taken part in and even a display case of medals in the corner near the entrance. It looks like both her students and her own medals, and I think to myself that she clearly does well here. I find that I am impressed with the whole thing.

But I can only distract myself for so long before my eyes are back on Gabriela.

She is leaning over Bella, showing her how to move her arms to protect her face. Why does she have to be wearing clothing that is so tight? Why could she not be wearing something loose fitting or a big tee shirt or something - anything - that would not have me feeling this way? I doubt that it would have helped though. It is just how she makes me feel.

I shift in my seat and adjust my pants which are feeling uncomfortably tight themselves.

I am getting more and more frustrated with myself the longer I sit here so I take out my phone and start flicking aimlessly through the news - trying desperately to stop myself from staring at Gabi. But it is incredibly boring, and I do not actually want Bella to see me on my phone and think that I am not being supportive - but I just don't know what to do about how I am reacting to the way Gabi is looking in that outfit and the way she is moving and stretching her fit body in the most amazing ways.

I sigh and put my phone back in my pocket. I really need to pull myself together, especially if Bella is going to be coming to more classes here. I look at Bella and see the giant smile on her face. She is learning a basic three-step punch sequence, and she looks so incredibly proud of herself. I try and remember when last I saw her looking this happy and it hurts my heart to acknowledge that I have not seen her this happy in over a year. This bullying issue has been draining the life out of her. It has taken the spark from her eyes - yet here she is now, with Gabi, and she is shining.

Yes. I will definitely need to bring her back here and sign her up for either the group classes or more one-on-one classes - whichever she prefers. Being in the group class would mean that she might make some new friends.

I wonder if she does one-on-one classes with adults. I grin and then horrified that I am grinning I frown at myself. What am I thinking? I don't want a one-on-one class with Gabi - wearing that. There is absolutely no way that that is a good idea.

When I hear Gabi saying that they can start their cool down I am so relieved that I can get out of here soon because I am getting more and more turned on and at some point, I am not going to be able to hide it.

Then Bella says she is not done yet and she goes back to the punching bag to work out more. I am both proud and upset by this because I really need to leave.

I grind my jaw waiting impatiently for them to start their cool down so I can leave.

But when they finish with the boxing gloves, and they actually do start the cool-down stretches my body goes crazy watching Gabi bending over. It is completely out of my control.

I feel my skin buzzing with electricity when Gabi's beautiful ass is bent towards me. Her tight pants are not hiding a thing. I picture my hands on her hips and try and look away, but the image stays in my head, so I look back.

She moves so gracefully, stretching out her body, leaning forward, and then stretching backward.

When she is on the mat, laying on her back and arches her chest upwards I picture myself leaning over her and pushing between her thighs. I feel my cock beginning to grow hard in my pants and I panic, but then it makes the thoughts more intense because my mind is now running wild. I picture myself with my arms pressing into the mat on either side of her head as she stares up at me with those dark brown eyes. She would lift her legs and wrap them around my waist, pulling my body up against hers.

Shit. Alex. Get a grip. I try and shake the thoughts from my mind. My cock is pressing hard against the fabric of my pants, and they have almost finished their cool-down session. Take a breath. Breathe. I look around. Feeling desperate. I glance over at them and seeing Gabi stretching again my cock throbs against the fabric even harder and I know that there is no way I'm going to be able to hide this.

Then they are walking towards me. Bella reaches me first and I think quickly - trying to figure out how to get out of this ridiculously uncomfortable situation. I take her water bottle from her and grab her gym bag from off the floor, lifting it onto my lap so that I can cover the obvious reaction I am having.

I am so angry with myself that I have so little control over my body with Gabi around. When she starts talking to me, I find myself snapping at her and being incredibly off.

It is better than her finding out that my cock is so hard it is threatening to tear the seams of my pants open.

"So, Alex?" What did you think? She did really well don't you think?" She is standing close to me, and I catch the scent of her work out on her skin. It taunts me as I picture her naked against my body, sweat glistening on both of our bodies and we push against each other.

"Ye - uh - she did great," I mumble.

"So, do you think she can come to the class tomorrow afternoon? It is a group class at four o'clock with the other kids. I think she will do really well in the team setting?"

What did she say now? Something about tomorrow. Fuck. Alex. Just get out of here now. This small talk is not helping anything, and you can't be in a situation like this. I feel frustrated and cornered in a way.

"Otherwise, we can do another private class." She is still talking to me.
