Videos where he won't swallow the blowjob spit

[Gwud]

I just find kinda hot when the bottom doesn't like to swallow the spit while blowing (for example: https://m.boyfriendtv.com/videos/170754/twinks-soldier-gets-spanked-and-fucked-outdoor/ ), I don't quite understand why people do it, but I've at least a couple of videos where the bottom does this, anyone has any video like this?

You mean the bottom spits out the cum after the top empties in his mouth??
