In the bustling university halls of Universidad Nacional Experimental de los Llanos Centrales Rómulo Gallegos, Venezuela, students let loose their inhibitions after dark. A group of coeds, led by the alluring Cuca, sneak into the deserted library for a late-night study session - of a different kind. With textbooks cast aside, they explore each other's bodies, their moans echoing through the silent stacks as they indulge in forbidden pleasures.
