A wife masturbates as a stranger joins him and they masturbate together

A skinny woman is inside her tent naked. She has a physically fit body and pierced nipples. She goes ahead and dips her fingers in her tight pussy, rubbing it vigorously. A man joined her as he slowly touched her thighs. He holds his dick tightly and starts to jerk off while looking at the woman's pussy until he cums on the woman's belly.
