You leave the table and go to your room to change, Grandpa follows you into the bedroom...He sees that you bent over quite low when you picked out your clothes and you have nothing under your skirt. Being a horny old man, pulls down his pants and enters your young ass. You are shocked, but you like the idea of your grandpa fucking your ass. You see your grandpa in the mirror, he's behind you, wasting your ass. You say to him, "Grandpa, that's not right! Grandpa, they'll hear us! Grandpa I'm so afraid you're going to tear my butt! Grandpa, maybe we shouldn't." But gradually the shyness and timidity pass, you start caressing Grandpa in return and suggest different positions for anal sex and fuck him until he cums. After that you say that you will go with his cum in your ass to finish the dinner, which is cooked by grandma. You thank the grandfather for such a wonderful gift for the granddaughter
