Three times is my guess, another user mentioned the laidley Worm of Bramburgh, in that legend a princess is turned into a worm by a witch and can only be saved when the prince kisses her three times.
She looks like a lamprey with that mouth, so obviously Youta needs to fuck her three times, or in three holes, or get her off three times... In lamprey form. Maybe get some top from her in toothyvagina mode.
