Sweetmarta, the insatiable stepmother, finds her stepson jerking off in his room, his big dick in his hand. She watches, licking her lips, as he strokes himself, his eyes closed in pleasure. She approaches silently, dropping to her knees behind him. He starts, but she shushes him, wrapping her hand around his dick. She jerks him off, her other hand reaching around to cup his balls. He leans back into her, moaning softly as she works him. She pulls him to the bed, pushing him down and straddling him. She grinds against him, her tits in his face, before moving down to suck him off again. She takes him deep, her eyes locked with his, until he can't take it anymore and cums all over her tits, leaving her panting and satisfied.
