"Ughh girls, come on..what the fuck!?", Stan remarked somewhat defeated. He was not really angry, he just felt odd about the situation. As much as he hated himself for it, deep inside he was somehow aroused, knowing his entire face is entirely coated in two beautiful girls' foot sweat. Immediately Amy pressed the ball of her left foot on Stan's lips, gripping his lips with her toes.
"Watch your language, little brat!", she yelled while making sure to smear further toejam on his lips to taste for later.
"Ohh wait, I almost forgot!", Jessica suddenly remembered something. She quickly fished a small paper block and a pen out her pocket.
"What's the idea?", Amy asked with a smirking expression, still having Stan's lips in a thight, sweat smearing grip. "Just a little upgrade for our cutie little foot reeko." That said she showed the note saying "Smell me" with three hearts surrounding the text.
"Just gotta make it stick." Jessica said, ripping the note off the block and bringing it to her extended tongue.
"No wait! Don't you think we should check if our creamy beauty mask does the trick?", Amy intervened with a teasing smile. Jessica gave a similar expression, as she extended her hand to Stan's forehead, sticking the note on and pushing it on the skin.
"Omg, it actually works!" Jessica said. She slowly removed her hand, but the note really stayed in position, stuck to Stan's skin just with the girls' powerful sticky foot sweat. "Hahaha, ohh it's soo beautiful! You are such a handsome little brother. Great thinking for not letting the sweat dry before sticking it on, Jess." "Yeah, would have been such a pitty..". Steadily, the sweat keeps seeping deeply underskin.
The outside of Stan's face appears less and less wet, more damp and the skin starts appearing a little swollen from the girls' liquid foot essence, that's now encaptured and a permanent layer of Stan's face. "Take a deeep breat, Stany-boy! Tell us, do you smell anything but our feet?", Amy asked. She removed her foot from his lips. *sniiieeeff* Stand took a deep breath, smelling the combined strong cheesy-sweet scent of two foot aromas stuck to him.
"Oh god guys, seriously?? No, I feel sticky and stinky as hell, my lips taste like a salty dorrito and all I smell is both your foot stink all on and in my nose..". Laughter erupted among the girls. "Don't be such a crybaby! We made such a great effort to give you this treatment", Amy said while again extending her left foot. "Now that we were so nice to you and you not even appreciating it, I think you owe us a little more fun. I know now it's harder for you to tell with our scent all over you, but we need to know how much of our smell has actually been rubbed off on you. Come on, give my foot a strong smell under the toes. Carefully sniff every gap and tell me how much stronger than your face it still smells." she said and didn't hesitate to rub the ball slowly under her brother's nose left to right, not pressing too hard to give him enough space to really suck in the scent into his nostrils. "See it as a challenge, Stany! You'll ingrain both our foot smells into you brain. Like that you can tell even the slightest difference in our smells, isn't that beautiful?" Jessica added full of enthusiasm. Stan didn't find the strength to answer, he just accepted his fate, carefully sniffing his sister's foot with focus, trying to sniff out how much sweat was still on it and where. The more his brain was flooded with fresh, strong sister-foot scent, the more he started to enjoy it in a weird way to him. That scared him a little.
Soon Amy also added her second foot, therfore doubling the line of foot smell. She still slowly wiped her feet from left to right and back and now also up and down to let Stan analyse the entire foot scent profile. "No rushing things, Stany..take your time memorizing every part of my feet. After me you still have to memorize Jess' foot smell for the next step." Amy said expectingly. Jess smirked at the thought, knowing what Amy had in mind. The girls carefully bathed every part of Stan's face in their scent, but one part was still missing...
