Ask if you can be with him forever
From Create Your Own Story
"I'd like to stick around for a while," you purr. "A very long while."
He looks you in the eye and smiles. "That can be arranged, sweetie."
Apparently his family is one with old money. Lots of old money. He takes you to a remote mansion in a beautiful country village ["One of many properties we own," he explains] and installs you in a wing of the mansion devoted to him. You are collared and leashed to a wall, leaving you access to about 10 rooms of the mansion, and given a personal servant. "I'll be here as often as I can," he says. "While I'm gone, she will be at your beck and call. Anything you want, money is no object. Just make sure you keep me... happy."
Over the years, his dick keeps you very happy. You enjoy your new life of luxury.
