My father-in-law like to take me to Liz Club on what they called fuck night where it was for men only and everyone was naked, and as long as all the sex was agreeable, there was lots of sucking and fucking. My father-in-law has a big cock at least 10 inches and I’ve been on the receiving end of it many times. I really saw him take it in the ass but on one night one of the members who was quite hung, asked him if he would like to get his ass reamed. My stepfather had me suck the BBC hard, then I watched him bend over and take the entire 11 inches up the ass. He was quite disheveled after the 30 minute fuck, and it took him some time to recover. My father-in-law turned towards me and told me to never bitch ever again when he asked me to fuck my ass.
