my room is yukimi shion, an older brother's only sopland.

When you were a child, I think that some of you have been to "doctors" with your sister and sister and local girls.Do you remember the excitement of those days? This young brother and sister are abnormal brothers and sisters who are not satisfied with "Doctor Gokko" but are doing "Soap Gokko" on a daily basis. I love my brother! His sister Shion, who really wants to eat with his brother, makes a simple sopland in her room. The story of a forbidden brother and sister Echiechi who enjoys the unrestricted launch course full of options until morning for her real brother opening at midnight when his parents have gone to bed.
