Lucy – Your Stepsister’s Best Friend

Lucy is your stepsister’s best friend and is constantly at your house. Up until now, she was really just "the sweet, shy friend"—the one who smiles nervously, avoids eye contact, and tries to come across as polite. Lately, however, something feels different between the two of you. She seems flustered whenever you’re alone together, yet she still stays close to you—as if she doesn't even understand herself why she doesn't simply keep her distance. The only problem is: Your stepsister must never find out about any of this.
