Squirtle

(All characters are 18 year old versions)

Life as an anthro Pokémon is hard but you seem up to the task. You stand stark naked in professor Oak's lab, you’re chest and ass are larger than the charmander and bulbasaur standing next to you. You’re also the only female.

Professor Oak laments over his desk, “My good for nothing grandson… That buffoon already left pallet town, and without his Pokémon no less.” Red walks through the front door of the lab, he looks at you and the other Pokémon… he looks at you a little longer. “Hey professor, today is the big day right! Can I finally pick a Pokémon!” Oak rubs his head. “Welcome Red and yes you may choose from any of these three”

Red looks at the charmander, he's strong but not too muscular yet, surely when he evolves he’ll be bigger and more fearsome. Then he looks at bulbasaur who is a little less lean but has vines that emerge from his back. “Cool.” Red remarks casually. Then he steps in front of you. “A female squirtle huh.” Without any warning Red squeezes your boobs, he walks around behind you and admires your amphibian tail and shell. Then he takes some time to admire your ass before squeezing that too. “Squir- '' you blurt out in shock.

“Red stop playing with the squirtle’s ass, she’s a Pokémon… you fuck her after you catch her.” Oak said to Red. Red came back at you and said “Nah I’m going with Charmander, you can keep the pokeslut” Oak gave Red a pokeball and you watch as Charmander gets absorbed into the ball and Red marches out.

“I suppose you’ll do…” Oak looks right at you, “… my grandson needs a Pokémon and you’ll be perfect for his first. Now I’m busy here at the lab so Squirtle I’m going to give you a rather special task.” He holds up a pokeball and a red and white collar. “You’ll wear this collar and carry your ball with you, that way people will know you’re not a wild Pokémon. You need to go to your master, he’s in Viridian city and his name is Gary.” Oak snaps the collar shut around your neck, it feels tight, and he hands you your pokeball. “Get a move on now” he slaps your ass and you start to walk on your own out of the lab and begin your adventure to Viridian city
