Kate, a dissatisfied wife, uses her husband's delayed return as an excuse to indulge her desires. She entices her stepson Tim, who struggles with his impulses but ultimately gives in. Kate's experienced mouth teases Tim's cock, and she guides him to fuck her from behind, her ass jiggling with each thrust. Kate's dirty talk and Tim's eager pounding fill the room, their illicit encounter only ending when they hear the garage door open, leaving them to quickly clean up and pretend nothing happened.
