Toph smirked, shoving the sole of her foot in Naruto's face, enveloping it's forms as his senses were attacked and engulfed in the smell.
Her foot slid easily along his face, as it was slimy and dirty from her constantly walking around barefoot.
"Get licking ninja-boy, if you ever want to get out of that hole" Toph said with another smirk as she kept her feet firmly attached to Naruto's face
Naruto was in hell, he struggled a bit but couldn't move, he could feel her earth-binding technique taking control of his body, as he helplessly began licking her feet, the smell invading his nostrils as it started to break him down, his will being crushed by the horrible smell of her feet.
Toph's feet were unlike anything he ever tasted, and it was hard for him to keep from vomiting but he was unable to control himself.
Toph cooed and smiled at Naruto's situation as she continued to rub her feet on his face, wiggling her toes in delight as he was forced to lick it, the foot didn't seem to get any cleaner as it was heavily coated in grime and dirt.
The sweat and dirt moved down Naruto's throat, as he was unable to stop it not sure how long he would lost.
Toph was lost in the situation loving it all, deciding to keep this up and have her fun for a very long time, she pondered what to do next.
