Hazel Moore has a crush on her older sibling's best friend, Sinn Sage, so Hazel is delighted that Sinn moved in to live with Hazel's family. However, being around her crush so much has made Hazel VERY horny, so when Sinn goes out to do some errands and nobody else seems to be home, Hazel takes the opportunity to masturbate. Meanwhile, Sinn realizes she forgot her keys, so she returns to the house to get them... and ends up catching sight of Hazel half-naked and pleasuring herself with a vibrator! Sinn is shocked but turned on, and starts touching herself while continuing to watch Hazel. Eventually, Hazel realizes that Sinn is there and becomes a bit shy, but when it's clear that there's attraction on BOTH sides, they eagerly come together for kissing and enthusiastic sex.
