Showing you this～ 'Under 18s should not enter carelessly'

Last summer, my parents went abroad. I had just come home from school, and the weather was really hot, making me sweat profusely. While I was wiping my face, my brother also came home. Huh? My brother looked a bit strange, constantly looking at me with a weird expression.

“Bro, are you hungry? I'll cook something for you.” My brother didn't respond and just sat there quietly. While I was busy in the kitchen, a pair of strong hands suddenly grabbed my shoulders from behind! I was startled and turned around to see my brother! His eyes were red as he stared at me. At that moment, he pulled out that thing! I immediately realized what he wanted to do. I struggled and shouted, “Bro… no! We're siblings. If Mom and Dad find out…” My brother's hands were very strong, holding me tightly. Under his desperate pleading, I became dizzy and did something foolish. Afterwards, I regretted it and didn't dare tell Mom and Dad. I was very angry! I ran to my brother's room and shouted loudly:

……

“Bro! If you don't do well on the next exam, don't ask me to sign! If you keep doing this, I'll tell Mom and Dad!” (Misinterpreted it, so I had to go back and face the wall for five minutes, haha)
