When I fuck and breed a bottom deep, he knows I've taken ownership of his ass--that's why I require breeding anyone deep the first time I fuck him if I'm to fuck him at all. Then, If he doesn't want to contain my load, then I don't want to know about it if he hopes I'll fuck him again; he can do that after I leave. (Unable to because the load is extra large is different, because, as a bigcummer, I like knowing when my loads are lots more than my usual.) If at all possible (and it is because of how deep I almost always breed), try to never let any go. The idea of pulling out to shoot on the bottom's back or ass comes from porn--it's the only way viewers can see for sure that the top did indeed cum from fucking the bottom; I do not do that unless it's agreed on as part of later-on variety. But, I will not cheat either myself or who I am fucking: If I'm fucking you and you think of changing your mind, I cannot pull out until I have plowed you as long as I need to and have bred you as deep as possible; when we're done, you'll know I was right.
