TSPX-018 - My cousin visited me in Tokyo, and she's all grown up now

Incest? It's legal between cousins. My cousin came to visit me in Tokyo. She used to be just a little girl, but seeing her recently, she's grown up so much. I couldn't help but see her as a woman. Turns out she's had a crush on me since we were kids. Once she arrived in Tokyo, I finally crossed the line.
