I stayed over at my best friend's house. He has a younger sister named Maya, who's really cute and a typical modern girl. She has a great figure and is definitely popular with guys. However, she's always letting her guard down—flashing her panties, sometimes even exposing her bare pussy—her subtle eroticism impossible to hide. I can't tell if she sees me just as her brother's friend or if she's actually trying to seduce me. Day after day, I'm left confused and restless, tormented by the sight of her.
