Since you are a virgin I will lick your hole first. That relaxes the anus, then use butter and my fingers to loosen you up even more before sliding my cock into you. I will go slow. Your ass will open up as my cock goes in, then it will tighten around my cock trying to push me out. You will have to bear down like you need to have a bowel movement. That will open you up, then my cock will go all the way in. Once your ass is used to my cock in you I will start fucking you. Slow at first then a little faster and harder.
