Neza, the young, innocent sister, can't resist the urge to touch herself in the privacy of her room. Little does she know, her brother is watching through the keyhole, his cock twitching at the sight of her innocent masturbation. She's so engrossed in her self-pleasure that she doesn't notice him until he enters the room, his hand already on his hard cock. They're both shocked but excited, their inhibitions melting away as they give in to their taboo desires, exploring each other's bodies with a hunger that belies their innocence.
