DASD-733 Ich Bin Der Einzig Vernünftige! Darüber, Morgens In Einer Welt Aufzuwachen, In Der Die Sexuellen Werte über Den Haufen Geworfen Wurden.

Originaler Titel: DASD-733 まともなのは僕ひとり!?朝、目を覚ますと、性の価値観がぶっ飛んだ世界だった件。

I live with a family of five, and we are a normal family, rather more uptight than other families. However, when I woke up in the morning, all the family members were naked and started having sex in front of me. My mother, sister, and sister continued to have sex with my father, while I could do nothing but be upset.
