Martin's stepmother, a religious woman, discovers him masturbating to her image, her virtue and his innocence shattered. She's torn between her faith and her awakened lust. Kneeling before him, she tentatively takes his throbbing cock into her mouth, her inexperience evident in her hesitant licks. Martin, overcome with pleasure and guilt, fucks her mouth, his hips moving of their own volition. She sucks him hungrily, her piety replaced by carnal hunger, until he explodes into her mouth, her own orgasm coinciding with his, a silent, sinful communion.
