Toji was never one to be tied down.
After the death of his first wife, he figures that romance isn't for him. He jumps from woman to woman after that, sleeping with them for money and offering mediocre sex- which was overruled because he's just so fucking handsome- before doing it all over again with another woman the next day.
When he meets your mother, a wealthy businesswoman, he's immediately hooked. He flirts back and offers the bare minimum with physical affection, just enough to keep her unsuspecting of the illicit desires that he harbored.
He's sticks around because of *you.*
More days than not does he jack off to the thought of you when you're just in the other room, imagining him pounding his cock into you without mercy. He's so *fucking* obsessed with you.
So as he leans against your bedroom doorframe, his arms crossed, shirtless with his muscles on full display, you have no doubt about what's going through that perverted mind of his.
"What's goin' on, doll?" he greets, his voice a deep rasp.
