Anime Porn - Gakuen Shimai Vol

Based on original work by Kino Hitoshi. Arisa and Mika Nanase are the school's super-idols. They are the school's sexiest and cutest girls. Sousuke is a regular student who, like the other lads, can only admire the super-idol sisters from afar. Sousuke likes Arisa but will never be able to converse with her. Mika informs him one day that she wants to talk to him after school. Later, he meets Mika and Arisa, who disclose that they are now siblings! The fact is that Sousuke's father, an adventurer, and the Nanase sister's mother, an archeologist, met at a South American digging ruin, fell in love, and married. Mika, Arisa, and Sousuke are now siblings and will share a home from now on. Sousuke must now be careful not to be caught masturbating by Mika or Arisa...or they may simply assist him... Why not take a bath with Mika?... After all, siblings do wash together...
