Sister Brothel (BABEL)

Synopsis

The protagonist’s little sister Saki adores her older brother and is always clinging to him. He finds her adorable beyond measure.

One day, Saki accidentally helps her brother with his masturbation and receives pocket money as hush money in return.

When Saki seems unusually depressed one day, he learns that a game popular at school is out of reach due to her limited allowance.

He wants to buy her the game, but their mother constantly scolds him for spoiling her. He tries giving her money for a shoulder massage, but Saki looks dissatisfied with such a meager reward.

Then Saki recalls the previous “favor” and suggests offering sexual services instead.

A sister in need of pocket money. A brother in need of sexual gratification. Their interests align perfectly. Thus, the little sister brothel is born—with handjobs at 100 yen and sex at 1000 yen.
