Actually I sort of know what you mean. When my wife's bull made me put his cock inside my wife's pussy, It was so big and hard ! heavy. I had to stroke it a little too because it felt so completely different !
That is so hot and you had to love it. I was tentative to do it but when I saw how much my wife wanted it and how hard she came when I ate and cleaned her, I was hooked.
Actually I don't know if you can see the sign on the door, it said "do not disturb" but I snuck in and videoed. Her bull does not liked to be filmed. lol
VERY true ! My ex wife said that she enjoyed my tongue more than my cock, since I am quite small and cum too quick, so she taught me how to eat pussy good. Lots of practice and now it is my favorite thing to do.
