17 inch means a belly bulge
For some its just never enough and they are always trying to expand their limits. You wonder what the intentions of this woman are, is she trying to transport the dildo from her pussy to her mouth? That would really be an achivement, i never saw that before. You can see on her belly that the dildo now reaches till far above her belly button, she needs some inches more to set a new record, pussy in, mouth out.
