Amy smirks as she watches Stan for a moment, smirking deviously before answering. "It's simple you idiot, my pet is here to help me, 'discipline' you. You should make yourself comfy because you'll get very familiar with her feet."
"What?! What do you mean by that?!" Stan asks with a startled expression on his face. Turning to Lin, Stan asks again. "What does she mean Lin?"
Lin averted her eyes in shame, having an embarrassed flush on her cheeks. Clicking her tongue, Amy shifts her sweaty socked feet teasingly along your face, smearing it with a putrid stench, then shifting them back she begins to strip them off one by one. Stan could only watch with disgust as your sister revealed her cute but sweat glistening barefeet. Much to your horror, Lin seemed to be staring at your sister's feet, transfixed in an almost hypnotic manner. Teasingly wiggling her toes, your sister speaks in a taunting seductive tone to Lin. "You want them you fat slut? Then you better listen close, show me your loyalty and dominate your boyfriend beneath your reeking feet. I know you haven't washed them in awhile just like I ordered so now is the perfect time to air them out and use my brother as a foot rest."
Hesitating for a moment, Lin glances from your sister back to you, clearly conflicted, then your sister's orders won out and she began to strip off her tight black boots, revealing her white stocking soles underneath. Stan watches in dread as Lin revealed her stinky white stocking soles in their full glory. A shy expression came to her cute face as she then walked over to her boyfriend and raised a plump beautiful foot up, scrunching them tauntingly so he can see the pink flushed sole through the sweat soaked stockings. Without further hesitation, she pushes one foot forward, planting the silky sweaty surface firmly against Stan's face, smearing across his cheek, leaving a plump foot print in it's place. Stan yelps as he falls onto his back while Amy chuckles evilly watching as his girlfriend steps down on his face, applying a painful amount of pressure, while a horrid reeking stench emits from her soles, making his head go dizzy as he inhales her toxic reeking stench. His eyes roll back while he feels the silky cloth of her stockings stick to his face, leaving a sweaty imprint in it's place while she rubbed and grinded her sole against his cheek and nose, bending it back and forcing him against the ground. She started undoing the laces of her other shoe while keeping him pinned, her expression being a bit sympathetic but also determined as Amy watched as his girlfriend dominated and demeaned him with clear enjoyment, thinking about all sorts of disgusting ideas to further degrade you beneath your girlfriend's hard working reeking feet.
