In this scene, a beautiful but possessed nun named Sister Mary is performing her daily rituals when she feels an intense urge between her legs. Unable to resist, she masturbates behind the altar while chanting demonic verses. Suddenly, a dark figure appears before her - the devil himself! He whispers lewd suggestions into her ear, fueling her lust even more.
The devil guides Sister Mary's hands to her own ass as they both lubricate it with holy water. He then penetrates her tight ass with his cock, sending shockwaves of pleasure through her body. Despite knowing this act is sinful, Sister Mary can't control herself; instead, she moans in ecstasy as the devil's long, thick cock fills her up completely.
They engage in a frenzied sexual encounter atop the altar, with Sister Mary's habit flying around them as they lose control.
