Sister Mia, the beloved holy woman whose enormous breasts strain against her habit as she blesses her adoring congregation, has kept her faith and her twin sister Ria safe—until Ria volunteers herself as the cult's 'holy saviour' and Mia realizes exactly what that title demands. To spare her virgin sister the ritual defloration, Mia offers her own curvaceous body instead, fitted with chained nipple and clit piercings that brand her as the 'Sexual Saviour' destined to serve thousands of believers. Stripped bare but for her stockings, the once-pure sister is passed among the cult's leaders, every hole claimed as she learns the full weight of her sacred new duty.
