The stepson's body tenses under her touch, his breath hitching as she traces the lines of his muscles. His mother, a stunning, confident woman, smirks, knowing the effect she has on him. She takes her time, her slippery hands gliding over his skin, her body pressed against his, her tits rubbing against him. He's rock hard, his cock straining, and she chuckles, a sound that sends shivers down his spine. She straddles him, her pussy sliding along his length, her juices mixing with the Nuru gel. She grinds against him, her clit rubbing against his cock, her moans filling the room. Then, with a wicked grin, she takes him inside her, riding him hard, her tits bouncing, until they both come undone, their bodies slick with sweat and pleasure.
