One evening, as they huddle in their cramped closet, they can no longer resist their forbidden desires.

They move together, their bodies slick with sweat and lust, their moans muffled by the dimly lit space. As they approach climax, they're gripped by fear and guilt, knowing they've crossed a line from which there's no return.
