Accept.

You picture yourself living with your grandfather and the thought excites you. You get up and walk to your Grandfather's room, heart pounding. You knock. He opens the door and smiles. "I see you've accepted." You nod and blush. He closes the door. "Now, first things first. In my bedroom, women aren't allowed to wear clothes." You blush, and strip off your pajamas. Your grandfather examines you. He then picks you up and throws you onto the bed. You look up at him, amazed at how fit he is, and spread your legs for him. "Good girl!" He says, as he rubs his head against you. He thrusts into you again, pushing your legs up so he can hit your g spot. The feeling is incredible, and you immediately want to melt into the bed. You can't take much of this and quickly cry out in a powerful orgasm. You grandfather sees this as his cue and unleashes what feels like a trainload of semen into your fertile womb. You pant for a bit before kissing him deeply on the lips. He rolls off of you and you quickly drift off to sleep.
