This happened a few years ago when I'd just become single and was starting yoga classes in Mexico city.

I was going about 3 times a week, and it was often the same students.

There was one guy that, for whatever reason, I would often find myself imagining having sex with. It was strange because he wasn't what I was attracted to. He was quite feminine and metrosexual, or possibly even gay.

On this morning we were lying on our backs in wind relieving pose. For non yogis, this is lying on you back and pulling one knee into your chests with both arms, to stretch your glutes.

But as I watched him lying there out the corner of my eye, I couldn't stop imagining walking over to him, pulling down my yoga pants and sitting straight down on his raw cock. I could feel the heat in my face, and my pussy lips getting slippery as I indulged this image.

As I continued to stare a his crotch, imagining putting my hand inside his pants to pull out his rock hard cock, I moved my knees slowly and gently back and forth, and was able to use my thigh to slightly rub my clit.

It didn't take long before I found myself quietly orgasming.I don't think anyone noticed, and I made sure to be the first out of the class, so not to show my wet patch on my yoga pants.

Who knew a yoga class could be so much fun! lol
