Oh grandson, I am so glad you came over. I'm making your favorite cookies, just they aren't quite done yet... I've got something important to talk to you about in the meantime. It's about time, and I'm so proud of you, for becoming the man of the house. It was about time you decided to keep it in the family and start pounding your sister. Your mother has told me all the dirty things you've been doing with all of your female relatives. Well, I've invited you over because it's... my turn. Since you want to hear what your moms been telling me, I go into detail about how turned on your sister is by you. But my cookies are getting close and I need some milk for them. Grandma isn't just wanting to see your cock, milk it... grandma is going to build you up to it. It's time you take granny, eat out her old cunt after I take a nice sloppy suck of your cock. Granny wants it in her fucking old gilf cunt, stick your dick in your little grandma and fuck me silly. I'm gonna cum all over my grandsons dick, it doesn't matter that we're 40 years apart... pump your dick in grandma while I orgasm all over it until you bust a nut at the same time and I beg you to put it in a glass. Let me milk that cock good boy, shoot it all out. What a massive fucking load for me to finish my cookies with. You are perfect grandson. Of course, you are right in front of me while I chew on, suck on and swallow your entire load. Grandma is so proud of you. But since you're already here... I want you to fill this glass up, grandson... But of course, you're a little wiped out from that massive nut and I'm so understanding, but I'll ask you over and over to make sure. You come back later, you hear? Granny wants more milk.
