The wife, unaware of her husband's hidden presence, grinds on her lover's cock, her pussy stretching to accommodate his size. The friend's hands grip her hips, guiding her movements as he thrusts upward, filling her completely. The husband watches, beads of sweat forming on his brow, his own cock hard from the forbidden scene unfolding. The wife's orgasm approaches, her body tensing, her cries of pleasure echoing through the room as she's filled with hot, unprotected cum.
