Motto! Haramase! Honoo no Oppai Isekai Oppai Maid Gakuen!

The main character loves big juicy boobs and sexy maids more than anything else. Every day he visits the Cafeteria where his childhood friend Mei works, and dreams of one day becoming a real cafe owner while playing a maid-themed social game. One day, his phone screen starts glowing very brightly and light gathers around. Before they realize what happened, he, Mei, and Mei's mother, Masa, are transported to another world. They arrive at the bath of a maid academy where various races learn to be the best maids! They meet nine maids who shake their beautiful plump boobs and mesmerize our hero...

Soon the chairwoman of the maid academy told our hero that the nine maids he met in the bath were cursed and cannot serve their masters. They are known as 'Cursed Maids'. However, the curse of this world does not affect the hero, a visitor from another world, and it turns out the cursed maids can easily serve him. The chairwoman begs the hero to become the master of these girls. To become a master of maids in the maid academy in Fifrecia, the country of maids... Of course, the hero didn't think long...

"I agree!!"

Thus, the main character finally became the master he had long dreamed of being. For the cursed maids, the appearance of a master was a long-awaited event. The maids compete with each other to serve the main character with their erotic bodies, arguing who will be the first. The mother maids also support their daughters by seducing the protagonist with their voluptuous bodies. Moreover, when the hero arrived in another world, he acquired an unusual skill, 'dirty service skill'. This ability enhances the sincerity and hidden motives of the maids, and both parents and children provide their dirty services to the protagonist. So, the goal is to win the most prestigious competition in Fifrecia, "MAID-1 Grand Prix". Who would have thought that these girls, hated as cursed maidens, would acquire a master from another world and later cause a big upheaval in the Grand Prix? The sexual battle of the protagonist, led by 10 maids (plus their mothers), including Mei, is about to begin!
