The HVAC man came by the other day, I was watching him out the window. I went outside in a little pair of shorts with a half stiffy to see if he needed anything.
He said no, then I went back in and watched him through the window. I stood in a place he could see me. I could see him start to get stiff as I got stiff.
I began rubbing my dick through my shorts and he started reaching into his pants for a handful of cock.
He jacked his fat donger on my window and then finished his HVAC job.
