As they maintain their virtue by not moving, religious guilt-ridden Michelle and her brother can't help but respond to each other's proximity. Michelle tentatively reaches for her brother's cock, soon enveloped by her own wetness. They fall into a passionate, taboo embrace, their bodies slick with sweat and shame, only to collapse into post-coital remorse, praying for forgiveness from their sinful lust.
