Under the watchful eye of their strict father, Luisa and Maria, two innocent sisters, find solace in each other's company. One evening, while sharing a bedroom, Maria feels a stirring in her loins as Luisa innocently caresses her shoulder. She looks at her sister's beauty, her heart pounding, and realizes she's feeling something she's never felt before - a burning desire. As Luisa reaches for her hand, Maria hesitates, then entwines their fingers, her breath hitching as they share a moment of tender, forbidden connection.
