My childhood friend 'Rui' and I grew up like siblings. We've been visiting each other's homes since we were kids, and even after she started living alone, she would still come to my place. One day, I noticed... Rui's breasts were growing unusually large during her developmental stage! Knowing this, Rui started her boob-and-panty flash double attack... Even if I tried not to notice, I couldn't help but stare. My childhood friend's cute and lewd temptation has pushed me to the brink!
