You accept the potion and roll a single d20 dice. You only roll a 14, which isn't too great, but definitely not an awful roll. So you drink about 75% of it. Then Brenda lifts you up by your ankles and pours the rest of it into your pussy and swishes you around since you couldn't easily do it yourself. She sets you back down, and while you are a bit dizzy, you can feel the potion taking effect.
The slimy mucus coating your body starts to recede back into it. However not without leaving behind a myriad of tattoo-like patterns on your arms, hands, legs, feet, and back. Those all then fade until they become nearly unnoticeable unless looked at closely. You finally are able to close your mouth again too, as the slime inside of it also falls back down your throat.
You are just about to relax, when you notice that you still are not breathing at all. Nor do you feel the need to. "Um, is it done now?" You ask, but the sound still emanates from your entire body, not just your mouth. You then feel something cool begin to pool inside your pussy. You look down to inspect it and are thankful it isn't gaping anymore. However after a single, "testing purposes only" poke, a glob of blue slime plops down out of it and falls onto the floor.
Both you and Brenda stare at the gelatinous blob of blue slime for a few seconds, then jump back when it suddenly begins to move. It moves directly towards you and is faster than you expected. But all it does is nuzzle up against your left ankle. You also feel a strange attachment to the little slime, an almost motherly bond even. "Hey, what exactly happened to me?"
"You evolved. You no longer are a Bikini Night Slime. You are now a Bikini Night / Slime Mother Hybrid. Your body is back to being human, externally speaking. Internally though, you are still a slime. This is why you do not need to breath, speak with your entire body, and can see in every direction all at once. Your body is your core. You now only can die if destroyed entirely, as in either disintegrated into nothingness or burned until not even ash remains. Finally, as I am sure you can guess seeing as how you just experienced it first hand, you are a mother slime. This of course means that every so often, you will give birth to a baby slime. What kind of slime you birth will depend on the area you currently are in. And you also are now loved by slimes, especially your children. They will never harm you or your companions again, and may even help you out if you are in need. I am sorry if you were expecting more of a cure. But this is the best I can do. I hope you are able to find a better one someday, but as for now... I hope this is a bit better for you at least." Explains and then apologizes the Witch Doctor.
While not exactly the solution you were hoping for, it is a lot better than before. You no longer are covered in slime at least. The auto-pregnancy part is not too inconvenient, but is something you will need to get use to. And the best part is that you no longer are overwhelmed by pleasure from the slightest touch! You check your stats and are slightly disappointed from seeing just a double digit HP, but the new skill "Perfect Auto-Regeneration" makes you excited. You also notice a new stat line has been added, Slime Family: 1/1. This seems to be the final upgrade to your Slime Commander skill you had, since it has disappeared. You inspect the new stat further and read the description:
"The number of slimes belonging to your family. The left number represents all living slimes that you are directly related to. The right number is a total of all living slimes who are part of your family, dead or alive, from all time. Not all slimes need to be birthed by you to be part of your slime family. Adoption of other creatures into the family is also possible if you posses the taming skill. Note that all tames will no longer be tamed, and will become your "children" in this situation."
You are interested in this ability as it seems like you can amass your own private army in a sense. Maybe you will have to find a way to get a taming skill somehow, if that even is possible. You then notice one additional new skill, Form Altering. It is a skill similar to Shapeshifting in that it allows the user to change their appearance. However this one lets you change even into completely different body shapes, where Shapeshifting usually only lets you change to something with a relatively similar body shape. The cost to use it is quite high though, so you likely won't be using it too much, unless you can come up with an amazing new form for combat or something to make the high cost worth it.
All in all, you are happy with the results. The annoying parts are gone, or at least minimized to the point of them not being much of a concern, and you have even gained a few new abilities out of it. The two of you thank the Witch Doctor and exit her building. Your baby blue slime is happily following right behind you. "So, where to next?"
