Cramped in a closet, religiously-bound siblings maintain virtue by staying semi-clothed. Michelle's baby brother's massive cock tents his pants, making her squeeze her thighs together, haunted by guilt. They freeze as their father enters, commanding them not to move. Natural lubrication soaks their brother's cock as the girls rub their tight, untouched vaginas along it, falling into a passionate, taboo lust. Post-coital, they collapse amidst smeared juices, praying for absolution from their forbidden desires.
