An ultimate fantasy program fulfilling the desires of amateur male performers obsessed with little sisters. Taking control of the script, "little sister" Riku Shiina playfully teases her groggy older brother upon waking, then tenderly licks his uncontrollably erect cock with her cute mouth in a forbidden blowjob scene. After school, in the afternoon, Riku gets caught between her beast-like boyfriend and her brother, their bodies drenched in sweat and saliva as they engage in intense, shocking sex. The realistic, everyday scenarios create an illusion so vivid it feels like reality.
