As the siblings pray together, their bodies press close, igniting an unexpected, guilty desire. The brother's cock stiffens, tenting his pants, while the sister's pussy dampens, her nipples hardening against her modest dress. They struggle to maintain their virtue, but the scent of their arousal and the heat of their bodies prove too much.

Their bodies move in sync, their inhibitions forgotten as they chase their pleasure, their moans echoing through the silent house.
