Under the watchful eyes of religious portraits, Michelle and her brother sneak into the study, the heavy velvet drapes providing a flimsy barrier. She's dressed in a prim school uniform, but her panties are damp with desire. He's in his Sunday best, but his collar's askew, his tie loosened. They come together, a feverish tangle of limbs, her skirt hiking up to reveal her ass, his hands gripping it tightly. He pushes her against the desk, her legs wrapping around him, feeling his hardness against her. She moans, "We shouldn't," but her body betrays her, arching into him, ready for the taboo dance they're about to engage in.
