Sisters, bound by secrecy and hormones, turn to each other for release. In their dimly lit room, they strip off their nighties, their breaths hitching as they take in each other's naked bodies. They kiss tentatively at first, then with growing hunger, their hands exploring every curve. One sister guides her sibling's hand between her legs, showing her how to stroke her throbbing clit, their moans echoing in the silent house.
