Under the cloak of night, siblings Isabella and Ethan, bound by blood and an unspoken craving, slip into each other's beds. Isabella, her body aching with need, straddles Ethan, her nightgown riding up to reveal her bare, moist center. Ethan, his cock hardening at her touch, grips her hips, guiding her onto him. They move in sync, their bodies slick with sweat, the room filled with their stifled moans and the rhythmic sound of flesh against flesh. As they reach their peak, Isabella bites her lip to silence her cries, Ethan's hot seed spilling into her as they share a moment of intense, guilty ecstasy.
