The priest's cassock rustles as he shifts, his bulge growing with each whispered sin. The altar boy, eyes wide with innocence and newfound curiosity, tentatively reaches out, feeling the forbidden hardness. The priest guides his hand, showing him the rhythm, the pressure, as they both succumb to the taboo. The confessional fills with their hushed moans and the scent of their shared sin, the priest's hot seed filling the boy's eager mouth, a secret communion of their darkest desires.
