Continue to resist

Your cock is noticeably smaller in all dimensions and it continues to shrink before your eyes. It has lost at least a third of its length already, closing in on half of its size.

"Please stop this." You say through gritted teeth, from both the pleasurable sensation and the terrifying nature of her magic.

"I warned you." Her voice remains a quiet whisper but is now undoubtably angry yet slightly exhausted. "I'll deal with her myself. Go home. I'll deal with your useless ass later." The hand releases your now approximately three-inch cock.

"What is this?! Fix this!" You point at your crotch, frustrated. "Fix it now!"

"Too late." You almost feel her lips brush against your ear.

The girl watches from her knees in fear and confusion when all of a sudden she's dragged away from you by her hair. She screams in surprise.

You stay in place, livid. You yell in the direction of the commotion. "Fix it!"

Exasperated, she whispers one last sentence in your ear. "If you are still here in five seconds, you'll never see your cock again."

Nothing she has done so far would suggest this is a bluff. You grab your pants and pull them up as you rush away down the alleyway, humiliated and not looking back.

Round the first corner, you fix your pants and make sure you're decent. You pat your crotch down in disbelief. Everything is sitting wrong. You wonder what to do next. Do you wait and hope she comes back to fix you? Do you try to find help? Is this permanent? Is this a horrible nightmare from which you'll wake up panting any moment?
