Entertaining with the plumber’s ass while he works.

I'm at home with my girlfriend when the plumber finally arrives to fix my problem with the kitchen sink. as soon as he arrives he goes to work and i am delighted while i look at that little ass that can be seen through his pants. i can not control myself or knowing that my girlfriend is winged and i start fucking her ass enjoying like crazy. although my girlfriend catches us i am unable to stop and i have a good time when the plumber starts jumping on my cock.
