In the dim light of a quiet afternoon, Sebastian, a young man with a secret, finds himself alone with his sister. As they sit close, the tension grows palpable, their eyes meeting in stolen glances. Sebastian's heart races as he notices her legs, bare and inviting. She catches him looking and, instead of reprimanding, she slowly parts her thighs, revealing the wetness that's been building. They're siblings, but in this moment, desire trumps blood. Sebastian's hand trembles as he reaches out, his fingers brushing against her warm, wet skin. She gasps, her eyes fluttering closed, and they both know there's no turning back.
