IENE-504 - I drugged my sleeping sister with aphrodisiacs and now she won't let me go!

I often write in these reviews that the beginning is crucial. However, in this case, the impact of Mao Hamasaki's breakdown in the first segment was so strong that the following three actresses couldn't help but seem plain in comparison. Especially since the third actress, playing the 'older sister' role, has such an attractive body... It's hard to give this a high rating.
