My photographer cancelled the shooting for today and I need new content for my OF. I ask my son to help me with them, he is hesitating but I convince him, after all he saw me naked many times. I start posing and soon my stepson cum inside his pants, he needs to work on his stamina so I tell him to jerk while he keeps taking the pictures to work on the endurance. He cums again fast. I tell him not to worry and that we can keep going. But as soon as I open my legs he cums again.... what did I do to deserve a stepson like this??
