ご奉仕メイドはエッチなお姉さん ～俺だけの巨乳メイドにたっぷり甘やかされるめちゃエロご主人様ライフ～

Shortly after advancing to a new school, the protagonist, Touya, loses both of his parents in a sudden accident.

Struggling to cope with his grief and uncertainty, he is taken in by his grandmother, who appears as his legal guardian. It is then that he learns the truth: his mother had been the only daughter of a wealthy family - and her marriage to his father had been, for all intents and purposes, an elopement.

Touya soon finds himself living in a lavish mansion, surrounded by maids. With beautiful older maids attending to his every need, he spends his days in a state of constant bewilderment.

Just as he begins to grow accustomed to life at the estate, he is informed that he will be educated as the family's heir. On top of that, he must choose one of his attendants - Chloé or Mashiro - to serve as his personal maid.

The doting older maids are so eager to cheer up their young master that they go a little overboard - leaving even his lower half feeling "energized"...

Ero-ero life as the master of slightly ditzy maids?!
