R夜書院 作品集vol1

R Yashoin Sakuhin Shuu Vol 1 includes four separate stories:
1 - モバイルガール
2 - 魔の森
3 - 夜の個人授業
4 - 花嫁輪姦式

As the stories comprise of different technical presentation (ADV vs. NVL, protagonist versus third-person narrative and so on, kinetic vs. branching plot), even the told stories differ greatly unless you could count the overall feature of sexual molestation.
