I like one very specific thing, which is Whumper locking the door after they enter the room Whumpee is kept in and wanted to expand upon i just a slight bit so:
Here's some fun ways to signal that pain is coming Whumpee's way (a ramble):
So in spot no.1 we got what inspired this post, which is the mental image of a Whumpee watching Whumper come in, then promptly lock the door behind them. It signals danger, it makes them feel even more stuck, so helpless. And the best part is that it signals that Whumper won't be leaving any time soon. When that door is locked, it means that it is time to hurt and I really can't explain any more why I have such an obsessive love for a locked door so utterly cutting Whumpee off from any hope of getting out of that room. Please consider the implications of something so simple and ponder on it for me
Another good signal is an alarm, or a specific time. Say Whumpee gets to endure horrific torture every day, but they are free to do whatever until that dreaded 7 pm comes when Whumper comes for them. They might have an alarm set up, which, if they ever manage to get away will haunt them for the rest of their life; or they might not, and they might not even know that it's already time before Whumper shows up out of nowhere and Whumpee gets this incredible expression of horror on their face and goes "Is it already time?" Chef's kiss, give me ten
We love our non-human characters and I specifically love non-human whumpers, so perhaps the signal for a whumpee who has the misfortune of being this terrifying Whumper's favourite is a quiver in the air when a supernatural all-powerful whumper enters Whumpee's home. A pressure on their body, a chill down their spine that comes right back up, a noise in their ears they can't get rid of, whispering in their mind. Hallucinations, inexplicable panic, a very specific smell, a distortion of their vision, the feeling of being watched, the feeling of another in the room though they are supposed to be alone, a feather/scale/puddle/literally whatever part of Whymper in the middle of their living room floor, the list goes on and on! I think we as a community should have more eldritch horror whumpers, it's got so much untapped potential and I for one could finally relate fully to the whumper as I am also a creature unbeknownst and inconceivable to mortals with a fondness for pretty little pathetic men crying on my floor :)
Oh here's a good one: Whumpee receives the signal from another person. "Whumper seems pretty frustrated." "Have you seen how angry Whumper got this afternoon? They looked about ready to kill." "Whumper wanted me to tell you they are waiting for you in their office." "Whumper keeps nagging me about you all the time. Why are they so obsessed with you today?" "I'm kind of worried about how long Whumper has been in their room for. I think you should check on them." Now doesn't all that sound just wonderful for out dear Whumpee, anxiously debating on whether they are going to survive today or not.
Of course, who's better to give the signal than Whumper themself? They could have a word they have taught Whumpee means nothing good. They could act a certain way, perhaps much too friendly or intimate, touching them, keeping them close. Maybe they don't even mean to send a signal, but Whumpee catches it anyway. That telltale glint in their eyes. The way they keep staring at them. Whenever they seem bored, frustrated, excited. When they call Whumpee's name in a specific tone that has an underlying want in it. Biting their lips a lot. Anything you can think of.
Rewards! When Whumpee recieves a reward, they know they are in for a bad time. I mean, they have to earn their luxuries, right? If they think they can just have that blanket or water without earning it it's really their fault for thinking that in the first place. Extra points if the reward isn't actually a good thing. Maybe Whumper got their Whumpee a new collar, or a new toy to try out on them, or they graciously helped them stay awake like Whumper told them to by electrocuting the hell out of them all night, and Whumpee dares to not even thank them?
And that is about as much as my brain can think of right now its late. If you wanna use any of these you are free to ofc though this isn't even a prompt list, more of just me rambling about tropes
Also the numbered list thing fucks with the readmore so i hereby apologize to anyone who will have to scroll past this seventy times on phone i legit cannot put one in there unless i wanna cut off the entire list and leave the first paragraph only. If it makes you feel any better I will also have to scroll past this
