Imagine growing up with Steenee as your little sister. As a young child your parents one day bring home a Bounsweet. All of you quickly bond with her and your parents start referring to her as your little sister. She usually sleeps in your parent's room but occasionally she sleeps in your room and you snuggle her. Throughout your childhood you take her training on occasion and eventually she evolves. You're so proud when you get home and show your parents as she beams with joy. You two grow very close and eventually she sleeps in your room every night. As you grow older and puberty starts to set in you start to see her differently. You always thought her evolved form was quite pretty but you start to notice her leafy skirt, emulating wide, sexy hips. As you cuddle her you start to get hard thinking about it. Eventually it gets so much you start rubbing your dick against her. She seems surprised but receptive. She moves down and takes you into her mouth. You hold her extra right that night. After a couple nights of this she lifts her leafy skirt revealing her cute slit. You slowly push your member inside of her as she squirms. She breathes heavily as you gently fuck her because you press your lips against hers.The next night you're more adventurous and do it quicker, turned on from her cute Pokemon moans. From then on for years you finish inside of her every single night. You take her on dates to Pokemon cafes. The appearance is of a normal Pokemon trainer taking their favorite Pokemon out for a treat. Everyone is oblivious to the truth of your relationship. When you're old enough to move out to your own place your parents allow you to take her, knowing how close you two are. From then on you and Steenee fuck for hours every single night. Despite being your Pokemon and your little sister she is the love of your life.

Haha wouldn't that be funny?
