How did she make the phone call with the gag? Consistency, child, consistency...
I love the theme of humiliation and this is a fantastic approach to it. I believe you could've added more details to her journey, interactions with other people, some strangers some not. Also add how she's feeling along the way, how her shame grows, but at the same time how she becomes horny.
Still it was arousing enough for me :)
