アスレチック男がペニスをしごいて、彼のお尻を指マンする

I jerk off my erected cock. My balls are retracted, my penis sticks out like a spear. I jerk off, my body tensing and quivering with pleasure in every muscle. I caress my anus. I put my finger in the hole and continue to jerk off. Only then I caress my dick ass, it's so nice!
