Setting up the scene and some roleplay with Jesse and her stepUncle. Jesse is alone with stepUncle Johnny and showing off her cute new pants. After a hug Jesse notices his boner which she investigates. Being a naive and inexperienced girl she doesn't know what this is and they discuss it together. This leads to stepUncle rubbing his cock between her legs until he cums all over her tight, shiny, pants, dripping down onto her feet. Tired from all the excitement Jesse wants to rest, but stepUncle has other ideas. Sliding his cock into her tight asshole he fucks her strongly and deeply until shooting his load all over her pants and stomach as she strokes his cock with her hand.
