Raelynn's heart pounds as she watches her brother sleep. Their argument earlier had left her feeling restless, her body aching for a release. She slips into bed with him, her hand tentatively reaching out to touch his chest. He stirs, his eyes meeting hers in the dim light. She leans in, her lips brushing against his. He responds, his arms wrapping around her, pulling her close. She grinds against him, feeling his cock harden against her thigh. He rolls on top of her, his fingers finding her wet, ready pussy. She gasps as he enters her, his thrusts slow and steady. They fuck quietly, their bodies moving in sync, their breaths mingling. As they come, they bury their faces in each other's necks, their bodies shuddering with the intensity of their taboo passion.
