This painting is inspired by a plot in Japanese R18 comics, where a young couple (usually high school students) is kidnapped by a group of hooligans, and then the girl is gang raped in front of a boy.
But there is also a situation where when a boy's face and figure tend to be feminine, that group of hooligans will gang rape both of them.
Then let the couple rape them while having sex.
......If I were to play the role of that boy, I would demand at least $100000 in compensation because the workload is too much.
Check.
