オープンキャンパスに行くために、上京する妹が心配で、ついてきた兄！もちろん泊まるホテルの部屋は一緒！兄妹と言っても、女と男だもん！ドキドキムラムラして、エッチしちゃったよ！
My brother who came with me because I was worried about my sister going to Tokyo to go to the open campus! Of course, the hotel rooms we stay in are the same! Even if we say brothers and sisters, they are women and men! I was so excited that I got horny!
