I like vore, I like ovipostion... (Post vore prey eggs, reformation eggs - insertions or laying) So why not both?

Basically imagine a prey hugging an egg or having one laid on them. Then being pushed in or out of a predator's butt, pussy, cock, or being swallowed.
Super tight can't wiggle free, get stuck inside or halfway in, a struggle for predator to get in or out of them.
Detailed bulge, outline of prey and egg because egg and prey are around the same size (or prey smaller) so being squeezed between flesh and egg is tight.

Theme ideas:
Normally not the predators intention to end up in that situation, but a lovely discovery or mistake during egg laying.
Prey trying to steal egg but mommy decides to take egg and prey into her to protect egg or the punish theft.
Predator trying to steal an egg but small prey trying to stop thief, like a kobold protecting their dragon master's egg.
Prey trying to hide from predator behind egg but gets sat on, the sudden wiggling causes predator to sit and shove egg in a hole by mistake but enjoys it too much to care what happened to egg.
Trying willing and safe unbirth with a girlfriend but goes wrong with egg causing mate to get lodged tight inside unable to get them pushed back out.
Female forced to carry both prey and egg for a long term or regress and suck them both into their ovary, or cum digest mate (or mate and egg in an unexpected orgasm).
egg and prey go in, only egg come out (or other way around)

TLDR: Egg. Eggs make fun toys but something to wiggle between egg and flesh is even better!
