The Pig only saw one way to keep Beth's body; she had to convince Beth to not only let her keep it, but to actively make her seem like the real Beth. But was there any argument that could make someone give up being royalty and willingly become livestock?
Would anyone give up their own identity for a Pig? She obviously knew the answer now that she was a human, but she still had to try.
If she failed then the outcome wouldn't be any worse than not having tried at all.
With that in mind, the Pig made her way back to the pen, hoping she would come up with a method to convince Beth on the way.
It didn't take her long to return to the pen that she had lived in until just a few hours ago, but finding Beth took her a while.
She found herself unable to differentiate the Pigs from one another, despite having recently been one,
and had never actually known what her own body looked like. She only remembered the reflection of her old face in the trough,
but finding an angle that allowed her to see the face of each Pig took a while.
She finally found Beth in the back, wildly rutting a Sow. The Pig blushed, unsure of what to do next.
This scenario was far removed from anything she had expected. She decided to wait until Beth was done, which resulted in her having to watch Beth mate for the Sow for almost half an hour. Beth squealed loudly as she climaxed, making the Pig's blush deepen.
She took a moment to steady herself, before approaching Beth. "Queen Beth?"
Beth turned her head, towards the Elf standing next to her, only realizing after a short while that it was her body.
The Pig bowed her head and continued before Beth was able to give the situation any real thought.
"P-please help me!" Her mind was racing, trying to come up with her next words, when she remembered how she found Beth.
"You like my body, right?" She hoped her guess was right. Beth seemed to think for a moment, before nodding.
The Pig started to become excited, but kept it from showing on her face.
"But I can't just pretend to be you, i'd be immediately discovered! Please help me, I can't do it without you."
She bowed her head again when she finished, scared of what Beth's answer might be.
Beth on the other hand thought that letting the Pig be her stand-in was a good idea.
She could still get the benefits of being a Queen, without having to be one herself.
Letting the Pig keep her body also didn't bother her, due to Beth feeling at home in it's former body.
And if she wanted to be humanoid again, then she could simply transform her current body.
Beth saw nothing off about the fact that she was willing to hand her body over to a Pig.
