So, there are these things called Tocolytic Agents, and they can be used to delay birth (specifically by stopping contractions) by a day or two. They're typically used in emergencies, and can have side-effects, but imagine there was some perfect version of this medicine, one without side-effects, delaying birth indefinitely if you wanted.
Imagine being far into your pregnancy, practically bursting with several pups, when your owner comes home with a new medicine! It's to help with your pregnancy, they say.
Some time passes, a lot of time after you were supposedly supposed to go into labor, and you still have to haul around your massive belly. Turns out you owner got you this perfect medicine, and by "helping with the pregnancy" they meant "delaying it as long as possible", so that they can keep taking care of you, watching you wobble with that huge belly, to could keep showing you around, flaunting you as their massively pregnant kitty ^w^
Maybe after a bit, you forget to take the medication in the morning that day, and you feel these painfully intense contractions, after being kept from birth from so long, it's like those pups are eager to get out!
Your owner isn't home.
It's going to be a very long, very painful birth<3
Hhholy shit you have no idea how much this entire thing just made me like
Uncontrollably wet/hard
Struggling to force out the first massive pup before my owner gets home, barely able to change positions from the sheer weight of the rest of the litter practically pinning me.
Only managing to have a sliver of a head crowning after nearly 5 hours of pushing, when my owner finally gets home <3
Screaming as the head is unceremoniously shoved back into me, and more medication is sent flooding through my veins to make sure my litter stays in even longer
