25-year-old Rio is a bundle of quirks with an adorable "anime voice" that's hard to imagine coming from a model-level body. She applied to be in a doujin AV of her own accord, and is a true masochist who finds utmost pleasure in being violated in both her vagina and anus at the same time. As she is relentlessly tortured in both holes, she moans in a bright, high-pitched voice, "Destroy me more!", and becomes so overwhelmed that she loses all sense of reason. Only in uncensored footage can you see the vivid depiction of her anus being stretched wide open and semen being poured into it. Her perverted nature, which combines cheerfulness and lasciviousness, will stimulate the viewer's desire to conquer to the extreme.
