A game of dare between siblings takes a provocative turn in their cramped bedroom. He dares her to touch him, she dares him to touch her. They start hesitantly, fingers brushing skin, hearts pounding. His hand lingers on her breast, feeling her nipple harden. Her hand wraps around his cock, stroking it to full length. Their breaths come in short gasps, bodies pressing closer. She guides his hand between her legs, rubbing her clit with his fingers. He groans, pushing a finger into her wetness. Their game of dare becomes a dance of lust, their bodies moving in sync, hands exploring every inch of forbidden territory. They don't stop until they're both panting, bodies shaking with their secret, intense orgasm.
