Looking out his bedroom window, Ty was struck by inspiration. In the next yard over, a young, light skinned girl was bouncing a soccer ball against her house and catching it as it came back. Grinning, Ty voiced his wish.
"I wish the girl I am looking at will get a sudden urge to come over to my house. No one will think this odd in any way and will ignore anything that might happen here, including any strange sights and/or sounds that might occur. I also wish that she will follow any and all commands I give her, while still retaining some of her original personality. Finally, I wish that should I have sex with a female, I will only get them pregnant if we both speak the phrase 'I want to have a baby' three times in a row while wanting it with all our being."
As Ty stared at the girl, she dropped the ball she was playing with and ran over to Ty's house. As he walked down the stairs, he heard a cheerful knock on the door. Reaching it, he pulled it open and looked down at the girl standing there.
Shyly, she looked up at Ty through her eye lashes and asked, "Can I come inside and play, please?"
Smiling gently, Ty opened the door more fully. "Of course, honey, come one in."
"Thanks!" she squealed as she skipped inside.
Closing the door, Ty followed her into the living room.
"So what do you want to play?" he asked.
"I don't know!" she said, not sounding disappointed in the least. "What do you want to do Mister?"
"Well, first of all, let's share names. I am Ty and I am 15. And you are?"
"Samantha, my name is Samantha and I'm 9. You can call me Sam."
"OK, Sam," Ty smiled, "How about we play a little game called 'Exploring bodies,' eh?"
"'Exploring bodies?'" she frowned. "I've never heard of that game..."
"Oh it is quite fun," Ty said. "Big kids play it all the time. You are a big girl now, aren't you?"
"Of course!"
"Good, then let's play!" Ty exclaimed, grinning from ear to ear.
"OK! What do I do?" Sam asked.
"Just do what I say, alright? It'll be fun, I promise!"
"OK, Ty. I trust you."
"Good," Ty said, thinking of what to have her do first. "Now, slowly take off your shirt, toss it to the side, and thrust your chest forwards. I'll do the same once you're done."
Still giggling, Sam hooked her tiny hands under her T-shirt and pulled up slowly, before yanking it over her head and tossing off to the side. Putting her hands on her waist, she thrust her chest forward as much as she could. Grinning, Ty walked over and kneeled in front of her, bringing his hands up and tickling her sides, earning a giggle from Sam. Moving his hands upwards, he used his thumbs to rub at her tiny nipples for a moment. Now laughing Sam cried out.
"HEHEHE, that tickles!"
Grinning, Ty leaned in and gave each nipple a quick kiss before standing back up and move back slightly.
"OK, my turn!" he said.
Slowly unbuttoning his shirt, he then flung it off to join Sam's, leaving his in his shorts and bra. Reaching back, he unhooked his bra, and tossed it over with his shirt, leaving his boobs bounce free, nipples hard from the cool air of the house and from sexual excitement. Once again kneeling, he beckoned Sam over.
"Now do I what I did to you, but use your whole hands for my nipples."
Sam reached out and touched Ty's side, gently moving upwards, earning a groan of pleasure. When she reached his breasts, Sam paused before cupping and hefting them. Staring at the mounds of flesh in amazement, she asked.
"Ty, what are these? My mummy has little lumps on her chest, but she never will let me touch or see them." She always says that I will know when the time is right."
Breathing heavily, Ty responded. "These are breasts, Sam. They can also be known as tits, titties, boobs, fun bags, knockers, hooters, and many other names. Women have them in varying sizes, and they are used both for pleasure, like now, and for feeding small babies. They produce milk which comes from those little puffy red nubs on the front of my boobs, called nipples. Many men, and some women enjoy seeing the sight of boobs, as well as playing with them, like you are now. I am odd in that I am male, yet have rather large breasts. You can stop now, if you want."
"Ah. OK," Sam said. "Will I ever get... breasts?"
"Of course you will," Ty said. "Perhaps sooner than you might think, if you are a good girl."
"OK!" Now what do I do?" Sam asked as she moved back to her original spot.
"Next," Ty said, "You need to strip out of your pants and underwear just like you did with your shirt."
Soon, Sam was standing nude in front of Ty, showing off her little hairless pussy. As she had been stripping, TY absently wished that he had a seven inch long human cock, with proportionally sized balls to go with it. He didn't want to scare Sam too soon. He also canceled out the 'Hung like a horse' wish since it apply anymore and instead set it to become erect once a female touches his cock.
Kneeling in front of her, Ty reached down and gently fingered her clit and pussy lips, earning another giggle. Grinning, he moved back and proceeded to strip, letting his cock flop out. Instantly, Sam zeroed in on it.
"Go ahead," Ty encouraged, spreading his legs slightly. "You can touch it, if you want."
"What is this?" Sam asked as she kneeled in front of Ty and reached up to uncertainly cup his roughly gold ball sized balls. Instantly, his cock twitched and slowly started to engorge with blood. Move one of her hands to his cock, Sam gasped as it throbbed and twitched in her grasp.
Moaning, Ty replied. "These are the male version of your pussy. Those hanging round balls that you are touching? Those are called testicles. They produce sperm, which is one half of what make a baby. Generally, the bigger the testicles, the more sperm is produced. They can be called testicles, testes, balls, and many other names. The shaft of flesh you are also touching is called a penis. It is what carries urine (what you would know as 'pee') out of the body, and also serves the function of depositing the sperm inside of a woman. It can be called a penis, cock, dick, shaft, member, schlong, and many more names. And before you ask, no, girls never get them."
"Awww..." Sam said. "They look like so much fun."
"Tell you what," Ty said, "Why don't I show you just how much fun they can be."
"Yay!" Sam exclaimed as she stepped back.
