Chug the potion

"Alright," you say, "I'll drink the potion. But this had better not be permanent."

You unstopper the vial and hold it under your nose. It smells faintly of mint. You press the rim of the vial to your lip and tilt it up, the thick fluid slides into your mouth and immediately you feel a tingle on your tongue. You swallow it and warmth spreads throughout your body.

A moment later you stagger back as a sharp pain shoots out of your clit. It feels almost as if someone is gripping it roughly and pulling it as hard as possible.

"Ahhh!" you cry and lean on Morina for balance.

You can feel your clit stretching, distending, experiencing new sensations as it stretches your damp panties. It's like all of the sensitivity you have become used to is being enlarged and spread out. You look down and can see the unmistakable bulge. You lift your skirt and to your amazement you can see a prick growing between your legs, semi-hard and already longer than your middle finger.

The hood of your clit has become a foreskin and the sensitive bud itself is now a pink head just visible inside the loose skin, complete with a hole in the center. You feel beneath it and you can still feel the rest of your vagina, so the potion seems to have only effected your clit.

"Oh my god!" you gasp.

"It's really big," Morina blushes, staring at your new cock through the sheer fabric of your panties.
