Hey man, not too bad for your first translation, the only thing that you got wrong was whenever someone says 出る they're talking about cumming, not saying take it or not don't take it out.
Like on page 2 where the dude says, "嘘だろ また出...", he's saying, "You're kidding me, I'm cumming again...", また meaning again and 出る meaning to come out. You'll see 出る, イク, 射精, etc, a lot if you're gonna keep on translating, and they're all just different terms for cum or cumming.
