Your first ever pokemon was a riolu you got when you was 10. You grew up, so did she, and now you two are like best buds

You get home from work, tired and hungry. You open the door and your lucario runs up to you.

"Master, let me look at your eyes"

You let her look into your eyes, a bit confused. After a while she jumps back and lets out a (clearly fake) gasp

"Oh my arceus!"

"Master, you definetly have poketitus...the symptoms include hunger, thirst, sleeping, sudden tiredness, nausea, and desire to bask in the sun."

Strange. You never heard of poketitus, but she is a pokemon, she would probably know more about this kind of stuff...but that kinda just sounds like normal stuff?

"Thankfully, i know the cure~"

You ask what it is

"The only cure is wild, sweaty, animalistic, wet, impish, reproductive, creamy (you know the word) with your starter pokemon! Regularly for a weekend!"
