My sister's Boin checks for 4G cup 92cm

Atashi's aniki is a so-called Akiba otaku and super sweet potatoes. I've been stuck in my room all the time, and as a younger sister, I'm jealous of you. But Aniki, you'll hear me say anything with Mr. M, and I'm a little S-included, so if I make fun of it, I'll squish! But, you know, I'm not going to be a good person at this rate, and my sister is bothering me.
