IPZZ-669 | My girlfriend's big-breasted sister is so unfair!! I couldn't resist the temptation of her beautiful round breasts slipping out of her bra and ended up cheating on her. Rui Nozomi

It's been six years since I started living with my girlfriend. As we've been living together, it's undeniable that our nighttime activities have become less frequent. One day, I found out that her sister from the countryside was coming to stay. I got a surprise when I got home from work! My eyes caught a glimpse of my sister's braless, defenseless body peeking out from under her shirt. Her baby-faced, petite, idol-like face, and her H-cup breasts—their unbalanced, erotic contrast—captivated me. Her flirtatious sister said, "You've been looking at my boobs, haven't you? Don't tell my sister." Her perfectly round, white, golden-ratio breasts tempted my crotch. I want to lick and suck them! I want to squeeze them! I want to squeeze them! Just as I was imagining all that, my sister pressed herself against me and said, "This place is getting bigger." No normal man could resist a word like that! Even though my girlfriend was nearby, I devoured her fair, lustful breasts! These addictive, devilish breasts are so addictive I'd want to taste them over and over again, even if it meant cheating! Bobobokku is a useless person who likes loli big breasts and is a failure to be human.
