Raised in a conservative household, Michelle and her brother have never acted on their secret desires. But tonight, as they huddle together in the dark, their bodies pressed close for warmth, Michelle can't help but notice her brother's erection straining against his pajamas. She reaches out, tentatively, and touches it. He jerks away, but she persists, stroking him through the fabric until he's rock hard. He turns to her, his eyes filled with a hunger that mirrors her own, and they finally give in to their taboo longing.
