Their father, a stern man of the cloth, instructs them to maintain their virtue while intimately entwined, yet the mere proximity of their semi-clothed forms ignites an unexpected fervor.

Their religious guilt-ridden minds clash with the primal urges that command their bodies, resulting in a heated struggle between piety and passion.
