Try to take the Zanalfil

You take the vial and pay for your purchases, staring at it while the clerk counts your change. He glares at you as hands you the money. He already doesn't like you very much.

"Uh, how do I, uh... do it?" You ask him.

"Just fucking drink it already." He says curtly, looking at you like you're an idiot. You hesitantly open the small vial and toss the contents into your mouth.

You gag at the unexpectedly foul taste of the bitter ****, accidentally coughing up the valuable liquid on to the chest of the tattooed woman below you as you retch. You cover your mouth far too late as you stare at the mess in disbelief.

"DUDE! That shit is expensive! You better not be wasting it!" The clerk yells at you angrily. Now some random stranger is telling YOU to lick up his disgusting medicine and not waste it? This was not how you saw your day going. This better be worth it.

You lap at the chest of the squirming slut, thankful you didn't hose her down earlier, trying to find every drop, but the small amount of runny liquid has drained quickly down the sides of her chest. She moves slightly so you can suck it off the counter. You don't think you got very much, but there wasn't very much to begin with. You hope it's still effective.

You pull your flaccid cock out again, hoping it quickly returns from the ****, but you just shake it around uselessly. You stick it between the eager piss whore's lips, wiggling it around in her mouth as she licks at you. Feels great. Still nothing.

You look up at the clerk, still giving you a stony glare, and laugh awkwardly. You remove it from her suckling mouth and begin slapping her face with it and the clerk deepens his frown.

"Dude, chill! It takes a few minutes to kick in anyway. Don't cockslap my girlfriend so hard." He says, annoyed. His girlfriend, still drunk on piss, doesn't mind in the least, probably even enjoying it. How are you supposed to get off if you can't even brutalize the cunt? Especially with this douche bag staring you down the whole time. You'd have a hard time with this even if you were horny!

You get the urge to leave, but you already took the Zanalfil under condition of giving this girl a feeder dose. He would be even more mad if you left without doing it after all this. You don't even know if you got enough of the **** to work!

You wonder what you should do now...
