Michelle and Ethan, siblings bound by blood and forbidden desire, find themselves alone and horny. Michelle retreats to her room, touching herself softly, her moans echoing. Ethan, unable to resist, sneaks in to watch. Caught in the act, they freeze, panting. Michelle's nipples harden, Ethan's cock tents his pants. They can't deny the electric tension. Michelle asks Ethan to join her, their eyes locked on each other's bodies. They masturbate together, Michelle's pussy dripping, Ethan's cock throbbing. Just as they're about to cross the final line, a floorboard creaks, breaking the spell.
