That's a hard one to answer. On one hand I just love to watch a guy cum and hear that pleasure as he releases his cum over me.
One the other hand, I love to feel his body tense and hear his moan as he cums inside me.
Therefore either one is good for me
I’d always cum where the woman wants, I love giving a facial but only if the woman is into that. One of our rules though is no cumming inside even with a condom, accidents do happen so I’d always pull out and ask any men we meet to do the same.
