In the dimly lit attic, the siblings find themselves entwined in a dance of lust and shame. She's a virgin, but her body aches for his touch. He's her brother, yet he's the only one who understands her. Their first kiss is tentative, then hungry. She guides his hand to her breast, gasping as he squeezes. He pops her cherry with a slow, careful thrust, both wincing at the pain, then sighing as they find their rhythm. They fuck slowly, deeply, their bodies slick with sweat and tears, their love a tangled web of incestuous desire.
