Helena stares down at you with an evil glint in her eyes. "Now, as you've been staring at my feet for the last hour, you've obviously noticed how dirty they are correct?"

You nod nervously in agreement.

"Good, now I want you to clean them," she said.

"How?" you ask, depending on how she answers this, you're both scared and excited.

"With you're tongue."

You begin to suspect your teacher doesn't understand foot fetishes, this is the exact thing you've been fantasizing about for a long time. You immediately want to begin, but you don't want Helena to suspect your enjoying this.
