Your friends with my step-son and you're staying with us for the weekend. You walk in on me naked in the shower. At first I'm embarrassed but then I realize you've already seen my naked body no need to cover up. To make it fair I ask to see you naked. You drop your robe and I get on my knees to suck your cock. You fuck me from behind and up against the shower. Then I ride your cock until you cum deep inside of me.
