I'm 6.5 inches, and the boyfriend looks to be around the same. The difference is I can't pound that pussy for hours at at a time. The BF cums, but stays hard and continues to fuck. My wife often says he fucks me until he is done.
My 4 incher, small as my finger, not as useful for my wife, so recently only eating her pussy before and after sex with her boyfriends, but no sex for me in almost two months now
