Suffering from a crazy case of blue balls,
the protagonist decided to break from his humdrum daily routine.
He would have sex with an escort. That's different, right?
Little did he know just how much that decision would change his life.

The escort agency provided gorgeous married women
who looked like some of his favorite characters.
Unlike many fuzoku services, this one allowed full penetrative sex.
When those horny wives seduced him, he was helpless to resist
... the happiest prisoner of lust you'll ever see...
