Step Bro Caught and Feminized

Ever fantasized about being caught wearing your sister's clothes? Can you tell I've thought about it a lot... what if she walked in while I was touching myself, and then she wasn't even mad. She just wants to make me into a good girl for her, so she does my makeup properly, cages my cock so I won't make a mess, and then makes me shove her dildo in my mouth. Mmmm. Thank you, sis!
