Raised in a strict religious household, siblings Michelle and her younger brother have never explored their bodies or desires. One evening, as Michelle prays, her brother enters, seeking comfort. She notices his bulge and, impulsively, reaches out to touch it. Overwhelmed, he pulls away, but Michelle's curiosity is piqued. They start meeting secretly, their innocent touches escalating into heated, guilt-ridden encounters. One night, as they're entwined, their father returns home unexpectedly, forcing them to hide their sinful acts.
