DASD-733 괜찮은 건 나 하나뿐! 아침에 일어나니 성에 대한 가치관이 엉망진창인 세상이었던 사건.

원래 제목: 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.
