Kei's Discovery

Kei walks through the corridor near the bar. "Why don't the grown-ups let me do anything,
I'm old enough." He says to himself. "It's probably because I'm not as big as them.
They don't ever trust people my size. Maybe Mikan has some medicine that'll make me bigger." He mutters as he takes the stairwell to the infirmary.
He opens the door and to his surprise, Mikan is not there. "Oh well, maybe I can find something myself." He says as he starts to rummage through the boxes and desks. He finds a bottle of pills called Enlarger. The description reads: "Makes men bigger." "Oh yeah! This HAS to work." he yells in excitement. "Hmm, the instructions say to take one a day, but that can't possibly be enough, I know, what if I take the whole bottle?"
He starts to uncap the bottle and finds a water bottle to help down all these pills.
It's not soon after that he starts to feel woozy. "I better lie down," he says as he makes his way to one of the beds, "I don't wanna fall."
He lies down and promptly passes out.

He awakes to find Mikan staring down at him.
"Did you take all of these pills?" She questions as she holds the now empty bottle over his face.
"Yeah..." Kei replies.
"Do you know what those even do?"
"They make people bigger. I wanted to get bigger so the adults would listen to me more."
"Oh.. I see. You don't need to be bigger for the adults to listen to you, it's just that they sometimes get caught up in their own worlds and forget that there are other people who have ideas too."
"It's not f---...." Kei starts to say until he's caught off-guard by an unfamiliar stirring in his loins.
"Oh, it looks like the pills are starting to work, Kei. I think you're in for a treat." Mikan says.
She moves over to his pants and starts to unbuckle them. "Take off your shirt." She tells him.
"Oh...aah, Alright." He does so, revealing his mocha skin and the body of a boy who likes to run jump and play.
Mikan removes his pants, leaving only his boxers. They watch on in rapt attention as the monster in his underwear begins to stir. It rises upward, quickly tenting his boxers. The show isn't over, however, as his privates continue to grow and push against the fabric. A mere 15 seconds later, it becomes more than the fabric can handle and it shreds, releasing a long thick cock into the air. It keeps growing and rising, and soon the rest of his boxers tear as his balls burst out from between his legs. Kei pants with pleasure as his junk grows and the smell of musk makes Mikan's legs run with desire.
Eventually the whole thing comes to a halt with Kei's enormous cock hovering 18" long and at least 5" thick, with balls easily the size of softballs. Mikan says "Are you ready for your big boy present?" as she stradles the table under his legs.
She grabs the head of his dick and pulls it toward her. Once it's close enough to her head, she puts out a tentative lick to his glans. The whole cock jumps as she does so and almost wrenches from her hands. Kei emits a loud moan as Mikan starts to pleasure his cock as best as she can.
She starts by licking upward from the base of his balls all the way to his tip. She does this a few more times until she attempts to engulf the head with her mouth. It's a tight fit, but she can squeeze a few inches in.
Kei is shaking in pleasure. He's never felt anything like this before. "M-mmore!" he cries out.
She works her tongue around the tip eliciting a squirt of pre-cum from his shaft. "Mmm, it's so tasty." She mumbles with her mouth around his mocha cock.
She pulls off and stands on the table over Kei, rubbing herself through her clothes. His shaft jumps and bobs with her scent and actions. She starts to strip herself, revealing a beautifully crafted body with C-breasts and a glistening cunt. She stands right over Kei's steel erection and drops herself on it.
Kei screams in pleasure as Mikan screams in a combination of pain and pleasure, his huge shaft penetrating her like none of these other men can do.
Just at that moment, a yellow glow overcomes Mikan and she slides easily down Kei's shaft. "Wh-what was that?" He says shakily. "I learned a trick or two up on the surface. Now I can take you without being cast in two and I'll stay perfectly tight around your enormous manhood." She replies.
She starts to work herself up and down his cock, moaning and screaming his name. She leans over and makes out with Kei. He grabs her tits and rubs the nubs playfully. She screams in his mouth and releases. He then proceeds to place his mouth around her left nipple and suck hard. More moaning and now pleading runs from Mikan's mouth as she rides his steel dick.
Kei changes nipples and Mikan continues to moan. "Hold on, I just thought of something. Stand up and lean over this table." He tells her. She obeys and he gets behind her and starts sliding his dick into her. He accidently lines it up with her asshole and he plows in. She screams again and moans his name, telling him not to stop and also that he has the wrong hole. He asks if he should change and she tells him not to.
He plows her ass with his massive tool over and over. He leans over her back and grips her tight as he sucks on her neck. "Oh, yes. Oh, yes. OH YES!" She cries again and again. "Fuck me hard, Kei. Fill me with your mocha shaft. Breed me with your studly seed." All he can do is pant heavily and moan as her ass grabs his shaft tightly. She comes to a stunning orgasm and nearly passes out, her sex juices leaking down her legs and on Kei's monster balls as they smash repeatedly into the table. "Oh fuck, fuck fuck, something is happening." He yells as his balls pull up as close as they can to his body. His shaft starts throbbing and he cums. HARD. His ejaculate squirts deep inside Mikan filling her to the brim in no time. Spray after spray of ball juice shoots out of her cunt as he orgasms inside of her. Not willing to let this all go to waste, she pulls away from him and gets on her knees in front of the stream. She puts her mouth around his cock and starts drinking his cum directly from the head. She can't keep up with the stream so much of it squirts out from the seal around her mouth and over his legs, balls, chest, and even face, while it also drips out onto her tits and the rest of her body.

"Oh my god, it tastes so good!" She cries in a mumble as she attempts to drink as much of his jizz as she can. The flow eventually comes to a halt after a couple minutes and Kei passes out. Mikan lies lazily in the puddle and muses about how this is going to change his life, and hers, for the better, she's sure.
