Alex has come prepared to deal with Ashley's bad behavior, though, so she confronts her when they get to their hotel. Ashley continues to be sassy, defensive, and rude.
Alex deals with this by turning her naughty little sister over her lap for a spanking on her bare bottom. But a spanking is not enough to address this kind of attitude-- Ashley needs a humiliating, childish, regression punishment.
So, she is spread, diapered, put into baby pajamas, and then marched to the bathroom to have her mouth washed out with soap. Good little girls do NOT speak to people that way!
Ashley is a lifestyle ABDL and spanko who has only done this type of video for Spanked and Diapered. Her authentic embarrassment is palpable in this film!
