It's been 6 years since I started living with my girlfriend. It's undeniable that our nighttime activities have gradually decreased as we live together. One day, her younger sister is apparently coming to stay from the countryside. When I came home from work, I was surprised! What caught my eye was my younger sister, peeking out from her shirt, a defenseless no-bra girl. I couldn't help but be captivated by the unbalanced eroticism of her childlike face, small animal-like idol face, and H-cup breasts. Her suggestive younger sister says, "You were looking at my breasts, weren't you! It's a secret from my sister." White, round, golden ratio breasts that bewitch my crotch. I want to lick and suck them! I want to squeeze them! I want to sandwich them! As I imagine such things, my younger sister also gets close and says, "This is getting bigger." If you're told that, a normal man can't resist! Even though my girlfriend is nearby, I devour and enjoy her fair-skinned perverted breasts! They're breasts full of addictive magic that make me want to taste them over and over again, to the point where cheating doesn't matter! I'm a worthless human being who loves lolita big breasts.
