Going to the gym makes me horny

I go to the gym every Saturday and Sunday, and during the week too if I have a day off or work from home.

On the way home I often have to hide the tent I've pitched in my trackie bottoms with my jacket. Now, by the time I get home, I'm usually so horny that my balls actually ache a little.

There's always at least one hot girl in the gym wearing something tight and sporty which of course sends my fantasies running wild, but I think there's something about the physical nature of lifting weights and working the machines. It probably fills my blood with testosterone.

Whatever the reason, I come home really fancying a good fuck.
