Mystery Girl by ImoutoCommissions

Pikachu is completely separated from everyone else, with no idea how to 
find his way back to anyone familiar. He is alone in Mewtwo's castle, 
confused and more than a little nervous, so naturally, when he hears a 
voice call out, it nearly gives him a heart attack. The voice is soft 
and feminine, and would be a lot more adorable to him, if he were not 
already scared for his life.

"What's a cute little electric mouse doing wandering around by himself?" 
the voice asks, and he turns to see a girl emerging out of the shadows. 
She has catlike ears and pale pink skin, and does not have a shred of 
clothing on her body, which leaves her adorable curves on full display. 
As she floats around him, her feet not touching the ground, her exposed 
pussy is at eye level with him, and suddenly, he is a lot less afraid.

At least, until he realizes that, behind her innocent air, there is 
power like he has never known before, and so, he is left both achingly 
hard and trembling in his terror. Mew does not seem to notice that at 
first, just floating around him and asking him question after question, 
not pausing for an answer, not even pausing to breathe, it seems.

"Where are you from? How did you get here? What's your favorite game? 
How long have you been here? Do you like to play?" But her questions 
come to a halt when she notices him tenting in his shorts. She giggles 
and says, "Does the little mousy think I'm cute?"

Pikachu can only offer her a numb nod, and she looks into his mind 
instead, to see what he has to offer her. She can see him with the 
various female members of his trainer's team, as well as with a Vulpix, 
with another Pikachu, and with a Jigglypuff. It seems like he has no 
shortage of partners, and she says, "Wow, it seems like you're a real 
stud! Well, I want some of that!"

His shorts seem to yank down on their own, but that is a result of 
telekinesis. She flips and hangs down in front of him, taking his cock 
in her mouth straight away, and at the same time, uses her telekinetic 
touches to tease at his every erogenous zone, leaving him trembling with 
pleasure like he has never known before. He is being touched in places 
where no one is touching him, and that leaves his head spinning, while 
his balls and his prostate and his nipples are all driven mad with 
pleasure.

With her legs wrapped around his neck now, she pushes her pussy in his 
face, and a voice speaks directly into his mind. Telepathically, she 
tells him, "It's only polite for you to return the favor!" At this 
point, his legs would have given out, if not for her own abilities, 
holding him steady with further use of her telekinesis.

He does as she tells him, leaning forward to start licking at her, 
hoping that he is at good at this as he believes himself to be. After 
the experience he has with the other girls he has had his way with, he 
can only pray that he meets this mysterious girl's standards, because 
she is strong enough to make him pay if he doesn't. But soon enough, he 
is so overwhelmed by how good it feels to have her suck him off that he 
is right there on the edge, and struggles to hold it all back.

She can sense this, can tell that he is holding back not just his climax 
but his electricity as well, and she is having none of that. Pulling her 
mouth back briefly, she says, "Just let it all out!" before going right 
back to what she was doing. There is no helping it now, and as he gives 
in, he loses himself to the most powerful orgasm he can ever remember 
experiencing, pumping her mouth full of his come while he shoots off 
sparks, electricity just rolling off of him.

The girl seems to love it, though, not hurt by the shocks, and 
swallowing his seed. When she pulls back, she rubs her stomach and says, 
"Your cream is so yummy, and your thunder left me feeling all tingly!" 
She gives him no chance to reply to that, or recover before she has 
tackled him to the ground with a hug, pressing her lips to him and 
giving him a dizzying kiss, all while sinking down onto his cock.

Pikachu had no chance to recover for this, and is immediately 
overwhelmed by the way she uses him again. Having her on top of him, his 
cock buried inside of her tight pussy, her lips on his and her tongue in 
his mouth, makes it so that he can hardly breathe. While she does all of 
this, she wraps her tail around his waist, until she is able to find his 
rear with it, and after teasingly poking at his tight hole for a moment, 
she starts to push it inside of him, and that is enough to leave him 
dizzy and overwhelmed, completely out of his depths, and completely at 
the cute girl's mercy.

Soon enough, she is fucking his ass with her tail at the same speed that 
she rides him, and Pikachu is helpless as he gives into another electric 
climax. She barely seems to notice, as she continues using him for her 
own pleasure, so caught up in it all that she just keeps riding him, to 
bring herself to climax after climax. Pikachu is always brought right 
along with her, shocking them both each time that she makes him come.

By the time she is satisfied with him, he slumps forward, passed out 
with a blissful expression on his face. She says, "Thanks for such a fun 
time!" But when she realizes that he has passed out, she giggles and 
says, "Oops, it looks like I overdid it again!"
