Ecchi harem isekai rp (M looking for F)

I'd like to rp as a perverted man sent into a fantasy world where he gains great power and gets a harem of girls as his entourage.

He can be reincarnated as a young genius noble. Has a childhood friend who works as his personal maid. Has an older girl tutor that he eventually seduces. Meets with the king, befriends the princess and the female knight general. Eventually gets his own territory. Will get advisors of even more pretty females.

Polygamy is common in that world, especially with nobles. So most girls would be pretty open with the idea.

Outside, he would look youthful, with a dazzling smile that none of the ladies could resist. Inside however, he would use his magic to constantly set up embarrassing ecchi situations with the girls, with them thinking that it's all accidental. He would also use aphrodisiac magic to make the girls horny, so he could peep on them masturbating. Even in sex, he would still keep his innocent act, even as he gives them ungodly amounts of pleasure.

I'm also into my character being absolutely innocent instead. Doesn't even know the difference between peeing and ejaculating. But he just keeps meeting with girls and women who want to get it on with him.

Edit:

Here's an actual plot idea.

Mithras Academy. Located in the smooth grassy plains of Arlium, it was the forefront magic school for the many noble sons and daughters of the many human kingdoms on the Feren continent, both major and minor, especially for those who preferred sending their sons and daughters to socialize and perhaps even form enough of a bond with each other so that they would be engaged easily in the future (due to the high mortality rate, the average married age was around 13).

My character was one of its students, Hugo Fleming, aged 11. The Fleming House had a small territory, only a mere village aptly named Flemingburg and its surrounding farmlands. His father, Cedric Fleming, was originally a commoner, only given the title of Baron as a reward for his service on slaying a rampaging dragon. He had retired since, using his newfound status and wealth to finally propose to his wife, Liliane, who used to belong to the Arcastel Family, one of the top noble houses in the Arcadia Kingdom where they resided.

Hugo was gifted with an incredible intellect, able to memorize and understand any books he read in a single glance. He also had a frighteningly scary talent in magic, able to cast the basic elemental spells when he was only three years old. Noticing said talents, his parents immediately gave him all the magic tomes they could get, resulting in him already mastering Intermediate level magic (able to cast them without a chant) and able enough to cast advanced-level ones once he entered the academy at age 11. They started to joke that he might be the reincarnation of Merlin, the Hero of Magic that saved humanity a millenia ago from a full scale demonic invasion.

The truth was, he was a reincarnation of someone else entirely. Someone he considered absolutely pathetic. Tired of the hardships of life, knowing that the only future he had to look forward to was bleak, he took his own life.

Only for a goddess named Mila to take pity on him. She decided to give him a new life, a (hopefully) easier and more meaningful one in her world.

She did not ask for anything in return. Only that he would live out his second life to the fullest.

You, on the other hand, would be playing an entourage of girls surrounding him. First, there would be his classmate, a girl the same age as him named Mary DuPont. She would be his "partner in crime", so to speak, always following him around, sitting beside him, and chatting with him. He first became closely acquainted with her after he stood up against a tyrannical teacher who had incorrectly corrected her exam, giving her an abysmal score as a result. Her parents were the strict sort who would scold her dearly if she got a subpar score even once. And so, ever since then, she became good friends with him, even to the point of her considering to ask him to become her "beau", her fiance and future husband.

The other early members of his harem would be a junior cleric of the Church of Mila, the Goddess of Sorrow, the very same goddess that brought Hugo to this world. Being a child abandoned at a church (by a prostitute, later on to be discovered in the story, possibly), she only ever knew the life of a church apprentice. She was treated well, and decently educated, but she was always eager to see more of the outside world. She was a cheerful, if, a little bit naive. Hugo first met her in an outing trip, as the church she was currently training in was close to the academy. He saved her from being attacked by a monster up on the mountains while she was gathering medicinal herbs, and from that moment on, she was smitten by him, thinking of him just like those prince charmings she found in her fairy tales.

The three of them soon found their life changed forever, as a freak magic surge teleported them far, far away from home. straight into the Alysma Continent, the eternal battleground between the human and the demon race. There, they would see war and conflict and brutality that would force them to grow up, as they seek their way back home.

I welcome your own character and story ideas, though I would have to approve them first. I also require you to reply on average once per day with at least 500 decently written words. I also want the typical ecchi common to the genre.
