Boredom and curiosity lead young, devout siblings into a secret closet rendezvous. Clothed but yearning, they struggle with their religious guilt, yet their bodies betray them, lubrication soaking their garments. They tentatively touch, then hungrily lick and envelop each other's virginities, the girl's tight, untouched vagina rubbing along her brother's massive cock. As they fall into a rhythm, they're interrupted by their father's voice, forcing them to separate in a haze of post-coital remorse and shame.
