Sister or Mommy: an ABDL story
For as long as she could remember, Crystal had been into feeling little, wearing diapers, the whole ABDL lifestyle. When she turned 21, she finally got herself an apartment and was free to indulge her fantasies alone… or so she thought. Her little sister, Angie, 18 years old, decided to go see what her big sister was up to. She finds her in diapers, playing on the floor and immediately assumes the new role of "Mommy".
Crystal is shocked at first to see her little sister being so dominant, but slowly accepts the new dynamic, going as far as wetting… and messing her diaper in front of her.
