The 60 minutes of the film are extremely uncomfortable followed by the joy of a girl named Onodera. At first, Onodera had to use a sextoy to stimulate her pussy because it was too itchy, but it didn't seem to help her much, but luckily at that time, Onodera's brother returned.
Onodera took the initiative to make her brother have sex with her, because there were no parents at home at that time, so the young man was not stupid enough not to fuck his "innocent" beautiful sister.
