In the hush of the night, a curious sister-in-law sneaks into her sister's room, drawn by the soft moans escaping from within. She finds her sister lost in the world of a naughty Sims 4 game, her fingers dancing over her sister's pussy, mimicking the actions on the screen. The sight is too much to resist, and she joins in, their bodies entwining as they mimic the lewd actions of their digital counterparts. The room fills with the sound of their wetness and whispered instructions, their games growing wilder and more taboo by the moment.
