Nenis, the elder sister, has always been the more curious and adventurous one. She's heard the whispers, the stories of the 'corno' lifestyle, and she's hungry to explore it with her younger sister. They start slowly, their hands tentative as they learn each other's bodies, their breaths hitching as they cross boundaries they've never considered before. Nenis' touch is firm, commanding, as she guides her sister through the dance of their desires. Their moans fill the room, a symphony of their shared pleasure, as they lose themselves in the taboo embrace, their bodies slick with sweat and desire, their hearts pounding with the thrill of their secret.
