PYPY-011 Piyo Piyo Growth Diary My Little Sister in First Grade Vol.9/Chinatsu Arai

A girl who's like a little chick, Chinatsu. She's 139cm tall, but Chinatsu, who is in the middle of her growth spurt and has passed her second growth period, is at an age where she wants to grow up a bit. Usually, she comes to me with an innocent smile and acts spoiled, but she throws a tantrum saying, 'I don't want to wear pink clothes all the time!' So I have a hard time too! No way, Chinatsu's clothes are decided by me! Alright, today you're wearing my favorite pink top and a fluffy skirt! What, you already don't like this childish stuff? Oh no, Chinatsu is going to be my wife in the future, so she has to stay frilly forever, or big brother will get mad w No choice, you can pick something more adult-like for your underwear. You'll take it off soon anyway w Her butt has gotten bigger, but her chest is still flat. Even though I massage her every day. 'Because big brother's massages are too intense♪' Chinatsu blushes and gets embarrassed, making me all moe and fluttery. Look, I bought a cat cosplay outfit for Chinatsu today, so let's put it on and have lots of fun together!
