Whenever my wife and I went over to visit her dad the first thing he did when he met us at the door naked was to take me to bed and fuck my ass. My wife loved watching her skilled dad with his big 11 inch cock making me squirm and cry out skillfully fucking my ass into the sheets. He was definitely the biggest cock that ever fucked my ass and I never did get used to his super size cock screwing me in ways I’ve never imagined. To get me over the humiliating embarrassment I always got a whipping afterwards, either with a strap or his riding crop. Even though I wasn’t a virgin, I still considered myself straight and getting fucked in the ass by my wife’s dad was definitely punishment. I don’t know who loved it more, my wife or her dad.
