Gia Grace's milf instincts kick in as she spots the cum stain on Johnny's pants. "Well, well, what have we here?" she teases, her large, round breasts pressing against her low-cut top. Johnny squirms, his face flushing, but Gia's not done yet. She straddles him, her big ass grinding against his lap. "Let's get you out of those dirty pants, Johnny," she whispers, fingers trailing down his chest. Johnny's cock strains against his zipper, eager for Gia's touch. She unzips him, revealing his hard, throbbing dick. "Looks like you've been a naughty boy, Johnny. Time for your step-mom to teach you a lesson."
