Soi fon picked up her pair of socks that had left on the floor earlier, and took an experimental whiff. She recoiled back immediately. They smelled worse than her shoe.

"Whew, they must have absorbed all the foot sweat that had built up when I was training today."

"Uhh, Soi fon, what are you going to do with those?" Yoruichi asked nervously.

Soi fon didn't answer right away, instead she just sat down on Yoruichi's lap. "Open wide, Yoruichi."She said holding one of the to her footslaves' mouth. Yoruichi actually looked a little scared. She had never done something like this before.

"Soi, I don't-" Yoruichi was cut off as Soi lightly slapped her on the cheek.

"What did I say about calling me mistress? Now open up like a good footslave." Reluctantly, Yoruichi complied. Slowly, she opened her mouth. Allowing her mistress to push the socks into her mouth. "And don't even think about spitting those out!" she commanded. Her slave nodded her head, even though the sweat from the socks was quite bitter and any other person would probably throw up, she honestly didn't mind the taste. Soi then decided to further secure the gag. Taking out a roll of duct tape, she smeared a few strips over Yoruichi's lips.

"And since i know how much you love to smell my shoes..." Soi fon positioned herself behind Yoruichi, leaving the other girl a little nervous. What was a Soi planning? She soon got her answer as her mistress pressed her shoe over her face. Then, wrapped the duct tape around yoruichi's whole head, careful not to get any of her hair, securing the shoe into place. Soi patted Yoruichi on the cheek, pleased with her work.

"There you go. Are you comfortable, my captive Yoruichi?

"Ymmph, mm mphmm" Yoruichi answered. It felt incredible, here she was, bound, gagged and at her former subordinate's mercy. She was unable to speak, and every breath she took was laced with the smell of her mistress's sweaty feet.

And she was loving every second of it.

"You look beautiful, Yoruichi." said Soi fon, stroking her captives hair and cheek with one hand. "Now what am I going to do with you?"
