just don't sniff her feet it's not healthy to be inhaling germs that predate the Renaissance

Remi kicked off her flats and let her bloodcurdling, garlicky feet rest. “okay Reimu, your flats are stunk up.” she said.
Reimu could smell the rancid odor and she wasn’t even leaning down. Remi's feet were just so toxic and it made her feel tingly. she stepped into her shoes and wiggled her toes. she felt her feet squelching in the thick sweat and slime that Flan has sweated into her flats, completely soaking into the defiled insoles and making it feel like a wet bathmat.
she inhaled through her nose and let the noxious gas flood her respiratory system. it was the foulest smell she’d ever experienced. she wasn’t even within ten feet of Remi's feet but the stench made her eyes water. five hundred years of unwashed, unclean, vile, disgusting feet, and the smell was now a part of her forever. she needed more of it.
Reimu threw herself onto the floor and grabbed Remi's feet, surprising the vampire. the foul stink was so powerful that her feet was clouded in a very faint green haze. she stuck out her tongue and gave Remi's feet a long, eager lick along the sole. immediately, the worst tastes filled her mouth. sour, stale, and utterly repulsive sweat, jam and slime covered her tongue. she swallowed and shuddered, feeling the gooey mess curdle in her stomach.
“wow, I’ve never met a mortal who has become addicted to my feet...let alone survived being this close!” Remi remarked as she rubbed Reimu's face with her damp toes. “from now on, you are my foot slave.”
Remi sat down and forcefully rubbed her biohazardous feet all over her, stuffing her toes deep into her mouth and watching her blissfully choke on the fumes. “lick them to your heart’s content, mortal. you will never be apart from them.”
