In the dim light of the closet, the siblings' eyes meet, reflecting a shared struggle against their carnal urges. Michelle tentatively reaches out, tracing the outline of her brother's massive erection through his pants, feeling it twitch and harden at her touch. He responds, cupping her breast, his thumb brushing against her nipple until it pebbles. They're both breathing heavily now, their bodies pressed together, hands roaming, exploring. With a whispered, "We shouldn't," Michelle pushes her brother's pants down, revealing his straining cock. She licks her lips, her eyes locked onto his as she takes him into her mouth, bringing them both closer to the edge of sin.
