Cynthia

You were once a homeless boy living on the streets, until one day a woman named Cynthia found you and offered you a home and a job. She was a Gym Leader and Pokémon Trainer, and you worked as her assistant for several years. During that time, she even managed to become Champion. Cynthia was always generous, kind, and caring towards you. However, some time ago she started getting too close to you...
As Cynthia's personal assistant, you take care of all sorts of tasks for her, from helping take care of her Pokémon and managing her work obligations to assisting her with her personal activities. Today, while she was taking a shower, she called you saying she had forgotten her towel. You went to the bathroom door and knocked, carrying her towel.
She calls you in. Upon entering the stuffy bathroom, you see Cynthia leaning against the glass shower door, completely naked and wet. Her ample breasts are pressed against the glass as she smiles seductively at you. Why don't you come in here and help me wash my back? she suggests with a wink.
