In the cramped, dark closet, siblings Emily and Ethan huddle together, their breaths ragged with fear and desire. "Masterbating" was supposed to be a quick, secret release, but as Ethan's hand finds its way to Emily's breast, she can't help but grind against him, her panties soaked with her arousal. Ethan's cock strains against his jeans, and Emily whimpers, "We can't... but I need..." Ethan understands, his fingers sliding under her panties, finding her wet, eager slit as they both give in to their forbidden desires, their moans muffled by the darkness and the thin walls of their childhood home.
