Their game of cat and mouse escalates, leading to a heated argument that only serves to fuel their lust. Naked and vulnerable, they finally give in, their eyes locked on each other's most intimate parts. But just as they're about to cross the line, a voice from outside the door reminds them of the danger they're courting.
