Step Sister is another H title that reuses the old plot device of a masochistic Male controlling others by under handed means. The main character, Kyosuke acts without regard to anyone but himself. But this, as mentioned before is a common H theme. The idea that his stepsister, Yuna is over 18 as translated in the English Dub, must have been changed from the original. She appears as a lolicon character at best. If you have any aversions to some unusual sexual practices, this is one you might want to avoid.
