Two people in the housing complex, my sister Konatsu and Imouto Ran, on a night when mom and dad aren't around...
A story of real and innocent sisters from a housing complex in the suburbs. Sweet and sour memories of summer days with cute and curious sisters. Dangerous play in broad daylight in a real housing complex. I love doing naughty things with my sister...(my sister). Ran, I'll definitely not tell mom and dad about today... (sister).
