The Gold Digger

[RedEve]

So the basic set-up of this game is as such:
A cynical, calculating young(er) woman decides to use her physical appearance and wiles to bag herself a very wealthy but considerably older man.
She cajoles him into marrying her without a pre-nup.
Her dastardly plan revolved around inheriting his fortune shortly after the wedding by simply exhausting the old man from the sheer amount of sex they will have.
Only to her surprise, the old coot is very sturdy and he has a stamina that puts men who are many decades younger than him to shame.

Now this is a very specific game as I am looking for someone to play a very old man relative to my character's age. At the very least in his late 70s, preferably in his 80s.
