I walk in on my step-son jerking off with the door wide open! I can't help but notice, his cock is soooo small, nothing like his step-fathers! I can't help but laugh and tell him all about his pathetically small cock. I encourage him to jerk off some more as I have never ever seen a cock so small, it's almost fascinating! I count down for him to cum for me, but it's such a tiny drop I can barely tell that my step-son has even came!!! It's so sad I almost feel sorry for him hahaha SPH, small penis humiliation, step-mom, step-son, cum countdown *Using customers name*
