Celeb Tsuma no Ana ~Koukyuu Manko wa Ore no Semen Nakadashi Benki~

By various turns the protagonist became a salesman for a struggling real estate agency.
As usual it was tough. He had sellable, good properties and knocked on every door in various rich residential areas, but everyone turned him away at the door.

Hard reality began to corrode his spirit, but he still had hope,
and who should he meet but a fantastically rich housewife of a politician!
This was his chance. He would sell her a property or die trying,
and happily this housewife introduced to three more prospective buyers.

But as he tried to conduct business it became clear
these wives were no ordinary customers.
One was a narcissistic tanning goddess, one an unforgiving career woman, and one the daughter of a highly respected lineage...
He had no standing with these women, to them he was working class garbage, and as he saw himself through their eyes his spirit broke.

And yet he didn't give up. He continued to visit the wives.
They had endless spare time and put up with him as entertainment, even flirted with him. That was the thread that connected them. The protagonist began to flirt back.

"You want to feel me inside you... Just sign here, would you please?"

A raunchy suxxxess story from rags to rape!
