Variation 2 by ImoutoCommissions

   When Pikachu is first turned human, he runs up to Ash to give him a 
fist bump. The boy stands at
   only chest height, with tanned skin and blonde hair, and he has the 
same ears and tail and red
   cheeks that he did in his Pokemon form. Though he doesn't wear any 
clothes, he doesn't seem
   ashamed of that at all, not even when he runs up to give Misty a big 
hug.

   Traveling with him in this form is a little unusual, but they quickly 
get used to it. However, he
   soon finds himself facing the difficulty of how hard it is to hide 
the way he admires Misty and her
   lean form.

   Now that he's like this, he has to actually hide his arousal, and 
each time he gets an erection, he
   struggles to do what he can to hide it without any clothes to cover 
it. It's more embarrassing than
   expected, to say the least, and even more so when Misty actually 
catches on, looking at him and
   giggling into her hand.

   "Would you like to borrow a pair of shorts?" she asks him teasingly, 
much to his humiliation.

   He puts even more effort after that into trying to hide it, though he 
isn't sure why, since she
   already knows. He even tries not to check her out as much, but that 
proves to be very hard for
   him. By that evening, he feels exhausted, somehow, despite not doing 
that much throughout the
   day. "Pikachu, will you come to my tent?" asks Misty, taking him by 
surprise. Naturally, he's quick to agree, following her inside and 
wondering what she's going to talk to him about.

"Do you have a crush on me?" she asks bluntly, and he feels his face 
going red.

"I want to take you as my mate and to breed you," he mumbles, deciding 
that being honest is his best option.

Misty laughs and replies, "Humans use words like lover and fucking." 
With that, she pulls off the shorts she let him borrow and gets down, 
surprising him as she wraps her lips around his cock.

Pikachu gasps in surprise and moans, melting into it as she begins to 
suck him off. The pleasure is so overwhelming that it isn't long before 
he's close, but then she suddenly stops, just before he comes, causing 
him to whine in frustration.

"Why did you stop?" he asks, in a needy tone of voice.

In response, Misty turns away from him, pulling her nightgown over her 
head and tossing it to the side. She bends over and pulls off her 
panties, her rear and girlhood in plain view, and says, "Because I'd 
rather you shoot off in my pussy than my mouth."

Pikachu can hardly believe his luck, and he lines up behind her, running 
a hand over her behind and marveling at just how soft and smooth her 
skin is before he presses his tip against her. He's small enough that 
pushing inside of her is not a difficult task, and she finds that it 
isn't painful having him inside of her at all. She presses her face into 
a pillow to muffle her moans so that Ash and Brock don't overhear her, 
and Pikachu begins to thrust into her, making up for his lack of size by 
managing to hit every sensitive spot inside of her. He's a quick study, 
as well, so he is able to read her reactions and learn just what feels 
best for her.

"You can do me as hard and as fast as you want," she finally gasps out, 
and Pikachu has just the idea of how to do that. Since he can still use 
his moves even in this form, he activates Agility to go at super human 
speed as he thrusts inside of her, her pleasure mounting rather quickly. 
When he couples this with Quick Attack, pounding her even harder, Misty 
loses complete control of herself, overwhelmed with orgasm after orgasm, 
forced to bite the pillow to muffle her screams of pleasure.

Pikachu can only handle so much of this himself, especially since she 
brought him so close before, and as she seizes up round him again and 
again, coming over and over again, it isn't long before he clings to her 
back, pressing himself up against her as he comes, filling her with his 
seed. It feels like liquid lightning inside of Misty, and she tingles 
from head to toe until she can't contain herself anymore, overcome with 
the strongest orgasm she's ever experienced in her life, the two of them 
crying out together with little restraint, and in the back of her mind 
she prays that the boys are already fast asleep.

Misty collapses to the ground at the end of it, rolling over and smiling 
at Pikachu. "That was so intense!" she exclaims. She looks at him then, 
and realizes that he's staring at her dripping pussy still, and that 
he's still visibly hard. "Do you really want more?" she asks, in a mix 
of excitement and fear.

When he nods, she says, "I don't know if my body can take any more of 
that! But, you know...if you want another round, then go ahead. If I 
die, at least I die happy!"

She hugs him tight to her when he climbs on top of her, and he starts to 
suckle at one of her breasts as he sinks back into her. Despite the 
intensity, she's able to withstand it, overwhelmed with pleasure all 
over again.

~X~

When she wakes up the next morning from a very deep, very exhausted 
sleep, she discovers Pikachu, back to his normal state, asleep in her 
arms, and supposes the spell must have worn off by now. She feels 
strange all over, in a way that she can't quite describe, but decides 
that it must just be because of the very intense night she shared with 
Ash's companion, and she doesn't think anything more of it.

It isn't until a few weeks later, when she's still feeling strange and 
misses her period, that she begins to understand the consequences of her 
night of passion with the temporarily human Pikachu.
