Katherine and her brother, Jimmy, are relaxing on the beach. Katherine suggestively puts sunscreen all over her body, focusing heavily on her breasts. Jimmy, laying on his towel, can't take his eyes off of Katherine. Jimmy tries to calm his erection straining his swim trunks, but Katherine's display is too much for him. Jimmy's erection gwos too large for his swim trunks and rips out of them. Katherine notices, and kindly offers to help protect him from the sun's rays. Jimmy, nervously agrees to her help. Katherine squirts sunscreen into her hand, then proceeds to sensually rub Jimmy's cock up and down with it. Jimmy loves it, but is too stunned with pleasure to say anything. As Jimmy's massive cock becomes fully erect, Katherine realizes Jimmy's cock is so big that she has to start use two hands to properly apply sunscreen to it. The feeling of getting jerked off and seeing Katherine's gigantic tits bounce while doing it is becoming overwhelming for Jimmy. Jimmy's balls are now large and swollen with cum. Katherine, while stroking Jimmy, begins to look around for more sunscreen. While Katherine turns her head away, Jimmy unleashes a torrent of cum on an around Katherine. Jimmy collapses from pleasure. When Katherine looks back at Jimmy and sees she has his cum on him, she genuinely thinks it's more sunscreen Jimmy must have found. Katherine then rubs a little of it onto Jimmy's cock and the rest into her skin. Katherine is so happy to help her brother out.
