GDHH-062: 『お兄ちゃん聞いて！なんか…私のカラダ変なの！？』ボクの妹（女子校生）はとっても純粋で何かあれば何でも話してくるし、分からないことがあればなんでも兄のボクに聞いてきます。ある日、そんな妹がいつもと変わらぬ様子で超エロい質問をしてきたんです！？

"Brother, listen to me! Is my body weird!?" My sister (a school girl) is very pure and will tell me anything if there is anything, and if there is something I don't understand, she will ask me, my brother. - One day, such a sister asked me a super erotic question in the same way as usual!
