There's another way to pay

As per the Pokémon League rules, the loser must pay the winner, either in cash or with their body. Seeing as Bianca has no money, you get to use her body. You inform her of this and she nervously gets into her knees and starts to unzip your pants. Your massive member flops out onto her face and she begins to nervously give you head. It's nowhere near as good as the Professor was and you grow annoyed.

You grab her by the back of the head and start thrusting against her head, fucking her face. Her gag reflex is surprisingly tame and you fuck her throat with little trouble. After a few minutes she gets into it as well and moves to match your thrusts. After a while, you blow your load down her throats and she gobbles it down.
