"Can you see it now? I'm way better than her, so let me keep this sexy body and I will lend all her holes for you." The elderly woman in my girlfriend body said. "Think about it, I can be your personal fuckdoll that you can use whenever you want, she would never be like that so it's a win win for us." Some failed experiment swapped around almost a bunch of people in my neighborhood, Bethany seemed normal, but I caught her stuffing her asshole with a toy like a pervert today.
She revealed she was not my girl but a old lady in her mid 70s from across the street, I was angry at first but then I saw how she wanted to please me using my girlfriend body. If I help her Bethany would lose her life, I know it's wrong but this old bitch knows well how to make me submit to her. I'm sorry honey, but I can't help myself.
After the scientists made a survey to know who was swapped I helped the new 'Bethany' pass the tests and keep her new form. I cried a lot after that, I felt like a monster doing this to my beloved. Happily, the regret vanished as soon as I was alone with my new girlfriend, the experience she had plus this hot body did wonders to me, I've never got a fuck so nice like that before. Now I think she's way better too.
