The Psycho Twins' Pet

Sin has no memory of how she came to exist, if she had family outside of the asylum she lives in, or if she was ever loved once upon a time.

Still, she dreams of a world where she can be free and loved and be whoever she wanted. But she has no idea what her life is really going to be the second she steps foot outside of that asylum.

-

Kidnapped and given to two men, Sin barely tries to fight them away. They're hot. They turn her on. Yes, she might be a bit unwell but she isn't stupid.

That is until she realizes what she really is. A pet. A breeding machine. A punching bag to suffer for eternity under the arms of these men forever. She likes how they turn on- but she doesn't want to die.
She hasn't seen the sea yet.
So she chooses the most reasonable thing. Get them to fall in love with her.

It's hard because they're literal killers and they're mentally insane. But so is she.

She has no idea if she's killed anyone yet but she's crazy, she isn't well, and she sure as hell isn't going to stop trying to escape. Hopefully.

If she doesn't fall in love with them first, that is.
