Increasing Word Count Without Fluff

>>My current word count is 25,000 and I need to get it up to at least 65,000. Right now, I'm focusing on adding more descriptions and going further into the characters' thoughts, but I worry these are slowing down the pace of the story. I personally get bored when an author does both of those things. Any suggestions? Tl;dr OP needs idea to increase word count.

What I do in this situation is start asking "What if...?" questions, then having my characters act out those what ifs and see where it goes.

I'll take a scene that feels like it could go somewhere and I start asking questions about it:

• Why did he say this? What in his life inspired him to think that way?
• What is he can control every device just by looking at it?
• "Why me? Why do these things always happen to me?" Why does he say this.
• What if, when on his way to here, he got hurt and had to spend a few days in a strange town/hospital?
• How will this other character respond when he finds out?
• What if he he is hiding a secret and this event/item/person is risking people finding out? Plus what is that secret and why doesn't he want them to know? What does he do to continue to hide it?
• What would happen if he went forward with this but that thing there happened to interrupt him along the way?
• What if he secretly had a wife and daughter, that no one in his current life knew about? (I did this one last year and blow the ideas so out of the water that it resulted in a completely new tory unfolding and 3 additional previously unplanned novels resulted from it, just to answer the question.)
• What if he got stuck in an elevator?
• What if he got amnesia?
• When he said that, what would have happened if this other person had disagreed?
• How would this scene have been different had someone drugged his food/drink?
• What if he went to prison? Justly? If so, what did he do and why did he do it? Unjustly? If so, why did they think it was him an how does he convince then he is not guilty?
• What if he were pregnant? (No, he is not a mistake here, and yes, I've had him, my male main character, end up pregnant twice in the past 3 years. The idea was so off the wall, it created in not only one new novel about it, but then a 2nd novel on the lines of: "Oh no, not again! Why does this keep happening to me?")
• What if it suddenly started raining/snowing while he was doing it?
• What if, he got trapped in a sudden storm/hurricane/blizzard and was forced to seek shelter in an abandoned church/ruins/castle/hut/cave? Does he snoop while he's there? If so what does he find? If not, why not and what does he do to pass the time while waiting out the storm?
• What is she thought he was doing it because of this when he was really doing it because of that?
• What happens when someone grabs his leg and drags him out of bed one night? Who are they? Friend? Foe? Why are they dragging him out of bed? Are they trying to save him from a burning building or are they pirates kidnapping him?
• Wait... pirates? How did pirates get in this story? Should I add pirates/vampires/dragons/aliens/zombies/something else to this story? Why? Why not? What would change if I did?
• What if he had no money… would they still love him?
• What if he could teleport, Star Trek style, to anywhere in the world? Where would he go? Why? What would he do there? How would the story change if he stumbled upon a transport device that does this? How does this change the story? (I did this one too, in a story sent in the 1400s, but they didn't get to pick when or where they went and I tossed then into the 1970s)
• How would the result be different if he did it here instead of there? This town/city/country, instead of that one? What if it takes place in a desert/jungle/tundra/arctic region?
• It's a dark and stormy night... so what does he do on dark and stormy nights?
• What if while he was doing this, that happened to mess up his plan?
• BOOM! "What was that?" he whispered. He peered outside and was surprised to see ______.
• What will she say when she finds out he did that?
• "Oh no, not again! Why does this keep happening to me?" Why did he say this?
• What if the world were about to end, or at least one character thinks so? How does this fear affect him? Does he believe his friend or laugh at him? What if he believed them but the world was not ending? What is the world really was ending and he didn't believe them?
• etc...

I've done every one of these questions and they've always helped me make my main character's life hell. :P
