If he doesn’t want it, he wouldn’t do it, right? He’s the one who is ejaculating…
I guess it’s happened accidentally, earlier in my BJ-giving career mostly, and in those cases I usually swallow because it just seems easier to do than, like getting up and running somewhere to spit…
Do we have a conversation? No I don’t call a meeeting about it with a guy, but there’s usually something like “Where do you want to cum, baby?” if he hasn’t made it clear… but also, if the ejaculation is not pre-planned it’s usually okay too!
