Fuuka is alone in her kitchen, looking a little disheveled as she feverishly stirs something into a teacup, then after a moment she hikes up her skirt and finger fucks herself, building up drips of wetness on her fingers to drip into the teacup. 

Lacey knocks then enters, giving her friend a hug. She asks what was so important, that Fuuka had asked for her help with. Fuuka hands her the tea and she sips absent mindedly as Fuuka sheepishly explains her situation. There was a drug trial she was on, she explains while squirming and unsuccessfully fighting urges to touch herself through her dress, pressing/rubbing her thighs together pressing her hands into her crotch, and occasionally absentmindedly licking her fingers, that the new drug trial she was on had a side effect of making people addicted to her pussy juice if they get even the smallest taste, and she accidentally dosed herself.
Lacey also starts absentmindedly fidgeting and staring a little more than she maybe should be while trying to be supportive, feeling turned on without really realizing why.
Fuuka explains further, now actively pinching her nipples and thrusting a hand under the dress, masturbating, that the effect is kind of like female viagra. Fuuka tells Lacey, sheepishly but without a hint of regret, that she mixed a little of the drug, and some of her squirt, in with her drink before you arrived. Lacey's too horny to really process this at this point and when Fuuka hops on the counter and spreads her legs to Lacey, revealing she's naked under the sundress and almost as if she were on auto-pilot, Lacey dives between her legs to eat her out. After Lacey shoves her whole face in Fuuka's pussy, like an addict getting a fix, they strip each other off and crawl on the counter - desperately licking and sucking each others bodies, tits, tongues and pussies. Fuuka Squirts in Lacey's face, Lacey squirts in Fuukas face, and dripping in each others squirt they grind, hump and fuck until they're spent, drinking in as much of each other as they possibly can. Of course, now they're both completely addicted to each others squirt and they can't possibly finish with just one time.. they'll have to keep going to get this out of their system.
