Siblings' forbidden religious rite of passage

Trapped in a cramped closet, a brother and sister find themselves enveloped in a thick, sultry heat, their semi-clothed bodies pressed together. As they struggle to maintain their virtue, the siblings can't help but notice the growing bulge in the brother's pants. The sister tentatively reaches out, her fingers brushing against the outline of his massive cock. He gasps, and she quickly pulls away, but the damage is done. Their bodies betray them, and soon they're lost in a frenzy of forbidden lust, their religious upbringing momentarily forgotten.
