Killing time with your niece - Live-action version -

My niece was originally attached to me. It may be because my brother and his wife were busy and often came to my house nearby. I felt my niece grow as I was about to enter school. I feel like I've been seeing her as a woman since then. During spring break, my niece watched a porn video on my smartphone. I thought it was bad, but... I crossed the line with my niece who was interested in sex. To kill time, she makes her squirt with fingering, makes her cum with toys, or do it without a condom. They have no romantic feelings for each other and continue their physical relationship out of curiosity.
