"I have to personally check if he's good enough for my sister!" One day, my sister brought her boyfriend home, but his appearance and overall impression were terrible. "What's so great about this guy?" I thought, so I decided to test him in various ways to see if he was a suitable boyfriend for my sister. First, I twisted his nipples 360 degrees from behind for concentrated stimulation! Then, I whispered filthy talk into his ear that made his brain feel like it was melting! As a result... He convulsed and ejaculated immediately! "Even with my sister right next to you, you're getting so turned on? That's the worst!"
