In a dimly lit, holy space, two sisters, bound by faith and blood, find solace in forbidden rituals. Clothed in modest garments, they kneel before their stepbrother, confessing sins in hushed tones. As penance, they must worship his throbbing cock, their virtue fading with each lick and suck. The air grows thick with incense and lust, their moans echoing off the cold stone walls as they take his length deep into their throats.
