If you feel a story is done then it's done, and while it's flattering for readers to ask for more you can simply tell them that you have told the story you wanted to tell and that they're free to imagine what else might happen - but you're not going to write it. If you do have an idea for a sequel then you can reply to them saying that you've got plans for a bit (or a lot) more, that you'll take their suggestions (if they made any) in consideration and that the sequel will probably be published in [time] so they should keep their eyes open - or follow you.
If you get a great idea from one reviewer's comment about wanting more even though you weren't really planning on a sequel and your story is already complete (and you like the ending), then you can always write a one-shot that you will post separately (as a new story) with an author's note that it was inspired by the suggestion [name] made. However, I think you should be really careful with this because it might lead to more people requesting (personal/specific) continuations and you might not be in the mood to do so but don't want to reject all of them either.
You could also simply add an extra chapter to your completed story if it's an epilogue and perhaps add a short author's note about how pleased you were with everyone's reactions and that you decided to write a short epilogue (perhaps set months or even years later) due to popular demand.
I don't know if any of this is helpful at all, because it's not really a specific answer. But in my experience it really depends on the mood you're in, how you feel about the (end of the) story and what your rapport is with the person who requested it. For example, I have quite a few regular reviewers who will always ask for more or they'll come up with suggestions what might happen in the future (hinting that I should write this) and I'm always polite in my response but often I just say 'no'. A lot of times I do give my input in what I think could happen in the future and give my opinion on whatever they suggested but I'm not going to write an entire story about it. Basically, if I feel I have told the story I wanted to tell then I'm done and will not write a sequel. But it has happened that people comment on the ending or what might happen later on that it'll spark an idea that just won't go away, so I tell them I'll think about it and to keep their eyes open - I usually end up writing a short sequel about it or make notes for a sequel in the future (I have too many ideas and too little time, so there's a big list of stories and some things will just have to wait). None of those reviewers have ever been offended to my knowledge, by the way, and they usually keep coming back for new stories too. So, it's really about the rapport you have with them and how you respond in your review/PM replies.
If you're not sure about what they're saying exactly and are afraid of taking it the wrong way (as a want for more when they're actually telling you one day you might be a good writer) then just ask them for clarification. Don't be afraid to ask! A lot of times such questions actually lead to more (and better) contact with your reviewers and from what I've been told by a lot of my reviewers is that they appreciate the responses I give them - some are actually surprised I reply at all and it usually leads to a great rapport with them, which means they're waiting for you when you start a new story.
