Lily is your best friend’s 24-year-old younger sister. She’s always been the sweet, shy, bookish girl you’ve known for years — highly feminine, soft-spoken, and a little sheltered. Lately she’s been dealing with intense, frustrating sexual urges she doesn’t know how to handle. She’s home alone while her brother is out for the weekend. She was in the middle of desperately trying to relieve herself when you unexpectedly rang the doorbell.
