First of all, you should never do anything that you’re uncomfortable with, so whether you want to spit or swallow is up to you.
There are a few options, once your partner comes you can either spit it on him, (though, that is probably something you would want to discuss with them first), or keep a cup handy to spit into. You can also keep a towel nearby, or just spit it on the blankets in a pinch. Good sex is usually messy sex, so you shouldn’t be too concerned about things getting a little messier. There’s also always the option of going into the bathroom if you have one at your disposal. Of course, that might cause your partner some discomfort, so to spare their feelings maybe tell them what you’re doing, so they aren’t horrified and think you’re just bailing on them. Communication is important here!
Of course, another thing to consider is that if you’re worried about the taste here, spitting is only going to make that worse since you’ll be holding it in your mouth for longer.
Also, if you really don’t want to deal with the spit or swallow issue, you can always let them cum elsewhere. Let them cum on your chest, or your stomach, or wherever you’re comfortable with — or not on you at all. You can always get them close to their climax, and then finish the job with your hand instead.
Basically, there is really no way you’re “supposed” to give a blowjob, or spit or anything else. The technique is up to you, and so is what you decide to do with the cum in your mouth. And don’t worry, if you decide you want to swallow instead, cum is good for you! (;
