I lie on the bed, exhausted after just walking in from a gym session, still wearing my workout clothes, still sweaty. I'm exhausted, but horny. I start to rub myself through my clothes. I feel my cock grow and harden, straining against the fabric of my underwear, constrained in my tight track pants. I remove my clothing and take out my cock... I pet it, I stroke it, I fuck it, I rub it on the bed.... I cum. I lie on the bed, spent and content.
