When their parents leave for the weekend, siblings Emily and Jake find themselves alone, boredom turning to curiosity. They start by sharing intimate secrets, but soon Emily's hand wanders to Jake's thigh, and he can't help but notice her hardening nipples. They explore each other's bodies tentatively at first, then with growing intensity. Emily takes Jake's cock into her mouth, savoring his taste, while Jake finger-fucks his sister's wet pussy. They switch places, Jake licking Emily's clit until she comes, then she returns the favor, bringing Jake to the brink before he pulls out and comes on her tits.
