Her dad was pleased that she wanted to come he would have some company for the first few days as her mum took to her bed as she was always ill when go...ng on holiday. Susan was thinking about the men that would be on the cruise. The cruise was booked 2 weeks in the Mediterranean, all inclusive what could be better. The day of the cruise arrived and after a couple of hours in the air they had landed in and soon on their way to join the ship. Once on board there was not much that could be done. “So, you’re pretty smart,” she said, “a genius of some kind or other.”“Yes, well, except when it comes to women. But, that said, guys are supposed to be dummies when it comes to them; it’s in the rule book,” I said.“Oh well, good. I was thinking about how I was going to get me an edge,” she said.“Huh? An edge?” I said.“Yes, I was just going to ask if you’d like to move in together. I mean I know with my face I don’t exactly have a winning ticket, but with you missing both of your gams, well, I. I had been so careful not to stare at her tits and sexy ass while I thought these incestuous things about her."Grandma, I…I…I'm not looking at you like that. You are my Grandma, and that would be incest if we did anything like that", I whined.“Johnny, I’m old enough to know when a man wants to drag me into his bed.”“No…no, you’re wrong Grandma. I would never be doing anything like that to you.”“Johnny, you don’t have to deny your feelings. It okay for you to have sexual desires. You are growing. ...I didn't authorize it and I don't condone it." She stood and watched me scrub myself with the freezing water, I was cold and shivering and sore. "You know MY rules" she continued. "You cum without MY permission.....and you pay for it...thats the rule.....for every time you cum, you owe me 100 blowjobs....now get dry...your first 5 cocks are in the living room waiting for you, and oh yeah.... theres a few girlfriends of mine who want to watch" On my hands and knees, with a fresh butt.
