You mother sounds really worried as she speaks. The real dildo must not be changing because it's not really you. You internally jump with glee as you joyously realize this has to mean she'll figure out what happened. "Adam? Adam please... please turn back." Suddenly you feel guilty, your mom did care about you after all. She might be thinking you're stuck that way forever.
"Oh!" You find yourself uncovered and looking up at your mother's embarrassed face. "You... Adam if this is you... I'm so sorry. That sister of yours will pay we'll make sure of it!" She holds you in one hand and the medallion in the other. "Your punishment is over. Go back to being Adam now." She says... and still, nothing happens. 'Mom! This isn't funny! Turn me back!' You scream in your head, unable to say or do anything at all.
"No no no sweetie change back please please!" The desperation in her voice makes you realize this isn't a joke. Something must be wrong with the medallion. "Dammit! This... this... thing!" Your mother grabs you and throws you into a drawer in frustration. "I can't change you back." You hear her say muffled. Your heart sank so to speak as you recognize she must still think the other dildo is you.
"Don't worry honey... this is all my fault. I shouldn't have done that sick punishment in the first place. What was I thinking?" She says between her sobs. "Well... you're not going to spend who knows how long as a dildo. I'm sorry baby, but the only other way to end your misery is to... I have to destroy the object you've become... and you along with it. You won't feel a thing Adam."
You hear steps moving away. 'Mom! That dildo isn't me!' You try hopelessly out of sheer desperation to get your mother to realize what she's about to do. If she goes and destroys that dildo, she'll think she's killed you out of mercy and just come back to use you as a sex toy again.
