In the dim light of the attic, siblings Michelle and John find themselves alone, their parents out for the night. Boredom turns to tension as they tease each other, Michelle's slender frame clad in a revealing nightgown, John's eyes drawn to her curves. As they argue, Michelle's voice rises, her nipples hardening against the thin fabric. John, unable to resist, grabs her, pressing his erection against her. They kiss, hungry and forbidden, before Michelle pushes him away, her face flushed. "We can't," she breathes, but her body betrays her, her pussy throbbing with desire.
