Journal de croissance d’une jeune nana : ma demi-sœur en première année vol. 11 - momoe-tan

Lately, my big stepbrother has been worried about my stepcousin, Momoetan, because she has been growing up. He has grown much taller, and I feel that his breasts have become more puffy. I don't want her to grow any more! I wish he would stay the same forever. I wish time would stop. Oh, Momoetan, good morning! Are you going out somewhere today? Are you going out with your friends? No, you can't go out dressed like an adult! You're supposed to wear a strawberry print shirt and a frilly skirt! What, you don't want to dress like that? I'm mad at you, big stepbrother! Today, you've got to put your stepbrother before your friends! Let's play cat costume with my stepbrother. What? He doesn't want to! He's rebellious, isn't he? You'll be punished for being such a rebel! Here, put on this leotard and I'll spray you with water in the bathroom! I'm sorry, or this will escalate! I'll do whatever you say, big stepbrother! Do you understand?
