Your mother happily accepts the polished medallion from your sister and begins her trek back upstairs to her room. You hear her click all the way back to her bed and she speaks to your dildo twin.
"Now I'm sure you're excited to get back to your own form, but remember this punishment next time you step out of line with the medallion. And keep in mind that next time I'll let your sister use you as much as she wants to." You hear a plush landing on your mother's bed, like she dropped her phone there, but you surmise that it was most likely it's your twin dildo.
"Alright here's the medallion, get to changing back." You hear.
This is so embarrassing, any moment your mother will realize that the dildo she had thought was you was actually just a piece of elongated plastic, and that the dildo she's been using for her pleasure practically nonstop for a week is actually her son. Some small part of you wishes that she won't find out, some small part wishes that this whole thing was just over. And another humiliating part of yourself wishes you could just carry on being your mother's tool of pleasure.
As you listen from your place amongst your mother's delicates, you hear you're mother say....
