You spend the day with your stepmother Cassy on the beach. You have found a secluded spot and are relaxing. Cassy has even taken off her bikini top so that she can tan her naked breasts in the sun. Meanwhile, Su is sitting at her iPad and surfing the Internet. You keep looking at Cassy's full breasts. You get a huge, thick erection in your swim shorts. Cassy notices this and says very hesitantly. Are you watching porn again or is it because i are lying here so exposed?
