"What do you think, Mickey? Lisa said she'd be gone at least three hours. Want to give your old Mother-in-Law a go. If your half as good as she tells me you are I'm sure this will be the highlight of my visit for both of us. Oh, and don't worry, I'm sure I know a few tricks that Lisa hasn't mastered yet."
"Is that an erection Mickey? No, don't be embarrassed, I'm flattered, and amazed. It's really quite impressive. What sort of nasty things have you been thinking about me to make that cock so hard? It's a good thing your Uncle Bob decided to stay home and watch the game instead of coming on the boat ride with us, don't you think? Take off those swim trunks and let me see. Oh yeah, that is impressive, especially for a High School boy. Now tell me, what is it about your Auntie Lisa that makes that young, teenage cock stand straight up like that? Is it my big titties? Maybe my long legs and pretty painted toes. I know, it's what's between my legs, isn't it Mickey? You've been wondering about my pussy, haven't you? Well, it's warm and moist and still quite tight, your Uncle Bob's dick is not near as big as yours, and I keep my bush very neatly trimmed. I tell you what, why don't I slip out of this bikini so you can check out my body from every angle and then we can decide how we will spend the rest of the afternoon."
"Thanks for escorting your old Gran to the fund raiser tonight Mickey. I'll be the envy of all the other old ladies with such a good looking young man on my arm. You look so good in that suit, especially that big bulge in your pants. Do you really think this dress makes me look sexy, even at my age? I'll tell you a secret, Since this dress really isn't made to wear a bra with, I didn't put on any panties either. That's right, Gran's going commando tonight. Maybe when we get home we can play a little game of "I'll show you mine, if you show me yours". What do you think Mickey, you willing to give your old Gran a go?"
