NPH-049 — Tsundere Little Sister's Defenseless Panty Flash Temptation - Hikaru Hikaru Minazuki

My sister brought her boyfriend home and said, "Don't look in my room," and had sex with him in the room. She knew I was looking in and was licking her boyfriend's dick to provoke him. My sister was frustrated with her boyfriend's sudden ejaculation. I was home alone with my sister and we were playing a game when I noticed her panties and got an erection. My sister noticed my erection and said something to me like I was making fun of her, so I spread my legs and she got excited. Our sexual desire was unstoppable, so I put a vibrator in her and she leaked. I made her take my erect dick deep in her throat and crossed the final line, putting my dick in her slit, and my sister was so excited that she couldn't stop leaking again.
