For CIM providers, is finishing with Snowball (cum swap with client) a big deal?

If you take a load in your mouth, instead of swallowing or spitting in sink, if you were then invited to just spit it out on his body or in client's mouth would that be better?

I figured if the client saved you the trip, and you Just could leaned over to spit it out rather than get up, it would be a welcomed offer?

Last time I offered she gladly took me up on it.

Its is very standard with a lot of girls, or at least the ones I visited.
And sometimes girls swallow right away, I had to remind a gal on Monday to wait and give me back my treat!
