Dawna hated Mike with a passion, all the while pleasuring him, sucking his cock, and doing the usual subservient whore schtick. But he'd made a mistake...
This was magic. And he'd wished that she'd have an infinite bladder. And that she could pee a river. She waited until he was at orgasm, gasping with pleasure, then raised her head back and took a deep breath, then let the floodgates loose!
The room was instantly awash with urine, boiling up over their heads while she held Mike down with his cock. He gasped, trying to order her, but sound didn't carry too well through urine, and as it jetted out of the windows and under the crack of the door, they struggled, until at last Mike went limp and lifeless.
Dawna felt her lungs burning, running out of oxygen herself, but she bobbed up to the ceiling and took gasping, ragged breaths as urine poured out of the dorm room windows. At last the tide subsided and she sat in the urine-soaked room with Mike's corpse and the lamp. The lamp that she could no longer touch, and no longer make a wish on without Mike's permission. And he was dead.
She wasn't certain what she'd been before--certainly not that she'd been Drake--but she had saved her friend Kayla from this monster anyway.
Now maybe Kayla could make a wish for her, return her to the way she was before, break all the enchantments on her....
