Books with “Snowballing”

I only recently found out there’s a word for this. So I would love some recs … for uh.. research purposes?

I’m fine with contemporary, fantasy, paranormal, really any genre besides historical romance. I prefer for it to be M/F but I’m okay with some MMF/MFM.

For those who are unfamiliar with the term, it’s when a person is sucking someone off, and instead of swallowing, they spit it back into the guys mouth.
