Bored and curious, these siblings stumble upon each other's secret desires. The brother jerks off to his sister's innocent panties hanging on the line, while she sneaks peeks at his showering body. One day, she catches him with his cock in hand, and instead of fleeing, she joins him, dropping to her knees to take his length into her mouth. He groans, fucking her face as she eagerly sucks him off. They're both inexperienced, but their bodies know what they want. Soon, they're naked, their bodies entwined, their hands exploring each other's virgin territories. They fuck hard and fast, their cries of pleasure echoing in the empty house, their taboo lust consuming them.
