AIDVDES-183 3rd Girls’ High School Student! Imouto-1 Grand Prix
The popular Sister-1 GP series features irresistibly cute high school sister characters in a fully immersive, first-person setup. This time, all of the sisters are blessed with beautiful, full figures. There’s the clingy sister, the shy sister, and the teasing sister, all saying, I love you, big brother! Of course, everything is shown from a completely subjective point of view, so both the sisters and their charms are all yours alone. Packed with five different scenarios designed to keep things exciting, this installment also includes a four-way rivalry among the sisters for your attention. Every sister is the perfect match for your ideal type.
Please note: Some video or audio noise may be present due to the original master tape.
