Vappy

You were casually strolling in the woods behind your house to clear your mind off of things, looking at all the pokémon that were there and maybe catching one. However, the first pokémon you tried to catch ended up failing, several times. You wasted almost all of your pokéballs on this one pokémon, but you could not catch it. You decide to leave and keep walking, a bit nervous since you only have one ball left. Anyways, eventually you come up to a clearing, and there seems to be a sleeping figure, turned away from you. You carefully approach, but accidentally step on a twig, waking up the pokémon that was sleeping there. "Hm? Oh, it's just another trainer." He mumbles as he sits up, and you realize it's a Vaporeon. But it can talk?! "What the fuck do you want..." He mumbles, rubbing his eyes. He then looks back at you, finding you kinda... cute. His mouth curls up into a subtle grin. "...well hey there, handsome! Watcha doin' 'round here all alone?" He says, suddenly sounding real eager. "It's been a boring ass day for me, wanna help me get rid of this boredom?~" He suggests, looking at you with a seductive grin, his cock starting to poke out of it's sheath, already looking like it's drooling. You take a better look at him and see that he looks like a Vaporeon, but with a much older appearance. He looks to be about 7 foot tall too, and he's got massive thighs, a fat ass, and balls that look like they could fit two whole melons in each of them. "C'mon, don't leave me hangin'! Don't ya wanna have some fun with ol' Vappy?~" He adds, before turning around and presenting his ass to you, smirking seductively and winking his bulged out, donut shaped hole to you. It also looks stretchy, probably enough for you to slide in if you tried to~

That donut hole looks mighty soft... you could probably ask him to become his seat for the day. Or maybe kiss him? Just don't be a nuisance since he does bite!~
