YST-294 — I Silently Devoured My Younger Sister Who Had Just Started Cosplaying. Amami Ichika

Ichika doesn't like to be in front of people, but when she cosplays, she becomes cheerful and energetic as if she is a completely different person. She poses cutely in front of her brother and the photoshoot begins, but the brother also has a strange sexual fetish and masturbates every day while fantasizing about his sister's still developing body. On this day, he has a private photoshoot with his sister, but the brother skillfully drags his sister into the world of eroticism and commits incest.
