It's funny to watch the boys went from hey let's devour some virgins to being confused after hearing noriko's nickman in school (onanie monkey). From that point, the two oneesans has taken the lead till the end of the story.

Roman number ten I guess, as this is the 10th marimite work according to afterwords.

[Synopsis]

The extraordinary life of slutty young ladies!
A duo of seemingly pure young ladies are picked up on the beach by men looking for sex and taken aboard a cruiser.
But their true nature is that they are hardcore perverted slutty high school girls who can only think about having sex with anyone!
A slut and another slut meet on the sea. If they are both dying to have sex, all they can do is make out with their lower bodies!
The young ladies shamelessly strip off their swimsuits and become completely naked in front of the men, indulging in erotic sex as their instincts dictate,
with masturbation, fellatio and raw sex under the blue sky.
A day in which the perverted slutty young ladies, soaked in semen from the depths of their wombs to the core of their brains, perform all sorts of lewd acts.
Enjoy a liberating, sex-filled summer with these girls.
