As the sun beats down outside, siblings Michelle and Jake find themselves alone in the house, their parents away on vacation. Bored and restless, they start to explore each other's bodies, their hands roaming under thin summer clothing. Michelle's breath hitches as she feels Jake's hardness against her thigh, while Jake's fingers trace the edge of her bikini bottoms. Their exploration turns heated, their kisses becoming more urgent, tongues entwining. They strip each other, Michelle's nipples hardening in the cool air, Jake's cock standing at attention. They grind against each other, their moans filling the room, until a sudden noise from outside startles them, forcing them to hastily cover up and hide their secret.
