It was a huge change.

It was a huge change for Kitten, when she turned thirteen and dropped ballet and stopped babysitting for her neighbor, so that she could focus on track at school.

She was very sad to stop babysitting for her neighbor. She told her parents that she didn't want to stop, but her mother scolded her:

"Catriona," her mother said, "the new coach says you have a good chance of being a regional champion..."

Kitten liked winning as much as the next girl... But...

"...So how about we give you some spending money to replace what you earn babysitting? That way you can focus on track."

There wasn't much that Kitten could say after that. Besides, the truth is that her neighbor's babies were bigger now, and his wife was working closer to home, so they hardly ever had any time alone anymore anyway.

Besides, she really liked running and she was really good at it. And the new coach at her school was kind of cute. Kitten kind of had a crush on him.

"Hey Cat!"

"Yeah Coach?"

"I wanna talk to you, after practice."

"OK Coach!"

"My office."

"Got it!"

Kitten--Catriona--was a little nervous, being in Coach's office alone after everyone else left. She leaned against his desk and crossed her arms, trying to act cool.

"So, Cat..." Coach was standing in front of her, looking down at her. He was a big man, a big strong man, and Kitten was small, even for a thirteen year old. He had his arms crossed, like she did, and it seemed to Kitten like maybe he was a little nervous, too. That made her heart flutter a bit.

"So Cat," he said again, "how you likin' track?"

Kitten was pretty sure that Coach didn't have her stay late after practice all alone in his office just to ask if she liked track.

"It's great!" she said, trying not to sound too nervous.

"Yeah? Do you think I'm a good coach?"

"I think you're a great coach." Kitten smiled nervously up at him and he smiled back down at her.

"We could spend some more time, just you and me, working on things," he said.

"I'd like that."

Coach moved a little closer to her.

"I think you're pretty cute, Cat," he said.

Her heart was fluttering like crazy now. "I'm kinda crushing on you, Coach," she said in a nervous little voice.

He was right in front of her now. He was reaching his hands out to her now.

Kitten and her coach kissed and kissed that day, she was leaning up against his desk and he was touching her, all over, his big strong hands on her little girl curves. She even worked up the nerve to put her little hand on the big bulge in his pants.

A few days later, Kitten asked Coach for a ride home after practice. She was anxious to show coach everything she'd learned from her neighbor.

They waited around after practice until everyone was gone, and then they got in his car.

He sat there with his hands behind his head, his eyes wide and sparkling, a big smile on his face, while little Kitten leaned over his lap and took his big cock in her mouth.

Kitten knew just what she was doing. Her neighbor had taught her well. She suckled and stroked and Coach started moaning, "Oh, Cat! Oh, fuck, Cat!"

He put his hands on top of her head, and then he grunted and moaned, and he lifted his hips in the air and pushed down on her head, and the first shot of come barreled out of his cock and into Kitten's little mouth.

She swallowed and swallowed as his come spurted out of him. She was surprised that it didn't taste anything like her neighbor's. But that was OK, she didn't really like the taste at first but she knew she'd get used to it, just like she got used to her neighbor's. All she had to do was give Coach lots of blow jobs, and she'd get used to it.

And that's exactly what she did.

It was after lights out when Kitten heard a quiet knock on the hotel door. Her heart beat hard. She was pretty sure she knew who it was.

They'd just competed in the regional finals and were spending the night in a hotel before heading home the next day. Kids were two to a room but one girl had to drop out and Kitten was the lucky one that somehow got assigned a room to herself.

Her heart was pounding pretty hard when she opened the door. Coach slipped in quickly, carefully shutting the door behind him.

"Hello, Cat," he whispered as he gave her a hug.

"Hey Coach," she said back.

They were on the bed kissing in a heartbeat. A few minutes later Kitten was suckling on his cock again.

"Cat?" he said, "Catriona?" He'd been laying down on the bed while she blew him, but now he was sort of sitting up and looking at her.

"'eah 'oach?" said, keeping his big head in her mouth.

He took a big breath. "Cat, how d'you feel about me?"

She was looking up at him now while she blew him, just like her neighbor taught.

"Huh?" she asked, taking his head out of her mouth for a second, then going right back down on it.

"I was wondering if maybe you wanna take it a little bit further tonight?"

She took his head back out of her mouth again, still looking up at him. She wasn't entirely sure what he meant.

But she knew that she wanted to take it a bit further with him, whatever that meant. There really wasn't any question about that!

As so little thirteen year old Kitten, le petit chatte, an piscin beag, looked up at her big, strong, grown-up coach who she was totally crushing on, and he was looking down at her with his eyes wide, and she said, "Yeah." And she kissed the head of his cock again.

Coach smiled at her.

"Come on up here, Cat," he said, reaching out to her and beaconing her up onto the bed.

As Kitten climbed up to join him, he pulled her nightgown off. She didn't even need to wait for him to start taking off her panties. Before he could even get her nightgown off, she was already pulling them down.

Then Kitten and Coach lay next to each other and kissed. While their tongues flirted inside her mouth, she could feel his big cock rubbing against her. Against the inside of her thigh.

And Kitten finally realized what Coach had really meant when he said "take it a little bit further tonight."

He reached down and took ahold of his cock and she felt it pushing against her.

"What about babies?" Kitten asked him in a quiet whisper. "Won't I get..."

"Hush, it'll be alright. Just relax. Focus on how it feels."

Kitten was incredibly sensitive. All sorts of feelings were overwhelming her, so that she almost couldn't even breathe. But she tried to relax and be brave for him.

Even though she was trying to be brave, she started crying when he took her cherry, because it hurt. But he stopped there, and just sat up on his knees and gently petted his little Kitten--stroked her hair, touched her face, fondled her breasts--with his cockhead just inside her broken hymen.

The sheer size of him stretched little Kitten open, and after a little while it hurt a little less, it just felt like she was incredibly full. And incredibly grown up.

Kitten kind of liked the feeling of being full like that, even if it hurt a little, and she gave Coach a sweet little smile. He gave her a sweet little smile back, and then he started moving inside her.

He was kneeling between her legs at first, but when he started moving inside her, he leaned over her while she lay beneath him and then he started moving his cock more, pulling back and pushing in.

Kitten didn't think about pregnancy and making babies anymore after that. She just focused on how it felt, just like Coach had asked her to. But she was really nervous, worrying that she was doing it wrong, or that she was too small for him, or that he wouldn't like it.

She could still feel the pain, it was still there, but she could feel something good growing behind it, something exciting and new and grown up.

But before she could really figure out what all these new feelings were, there was this weird thick rushing feeling inside of her, and Coach's face went all tense and red, and she knew he was coming in her.

After he finished he just lay on top of her for a bit. Kitten was so small, and Coach was so big, it was a bit too heavy for her and she felt kind of crushed underneath him, but at the same time she loved the feeling of it.

She was just getting to the point where she knew she'd have to say something to him, so he'd get off of her, when he moved and smiled at her and called her his little woman.

"You're my little woman, aren't you, Cat?"

She smiled and nodded.

"I'm really proud of you," Coach said.

And Kitten--Catriona--felt a glow inside of her.

After they lay there together hugging and kissing for a while, Coach got up and went to the bathroom and came back with a warm, wet washcloth and very gently cleaned little Catriona's bottom and vagina, wiping the blood and the come off of her. Catriona felt very happy that he was so kind and sweet to her.

Then he snuggled up next to her and put his arms around her and held her tight.

A few hours later, Coach woke Catriona up and told her that he needed to get back to his room soon. Otherwise people would notice. Catriona felt sad about him leaving, but she understood. Then he asked if maybe she'd want to do it again before he left.

Catriona definitely wanted to do it again.

"Let's make sure you enjoy it more this time, Cat," Coach said. "Here, lay like this--" He crossed her legs so that she was sort of on her side, half on her side and half on her back. "This way I won't go so deep and I don't think it will hurt so much."

He mounted her then, holding himself above her and thrusting in her and it didn't hurt! Well, it almost didn't hurt. But it felt amazing! And then he reached his hand down into her crotch and started rubbing her little clitty and--

Catriona started gasping and squirming and pushing back against him, and his huge cock felt so wonderful, thrusting so powerfully into her, and she felt her face go flush and her body tingle, and the tingles turned to waves and the waves to cascades and she came. Catriona came while Coach thrust his huge cock into her, over and over, thrusting and thrusting and she was his little woman as he came in her the second time that night, the same weird warm rushing feeling and him gasping and going tense and red in the face.

Coach helped Catriona change the sheets before he left. And then he gave her a sweet kiss and said goodnight to her and left quietly to return to his own room.

And as Catriona lay in bed afterwards, trying to get to sleep, she knew she was crazy about him. And she knew she loved to fuck.

The next morning Kitten was worried about babies again. But coach took her to the pharmacy and bought her the morning after pill, telling the pharmacist that he had caught her with a boy, which was terribly embarrassing for little Kitten but he apologized afterwards and she knew he was taking care of her and that made her feel loved and cared for and wonderful.

It had been a scary, crazy, sweet, beautiful night for Kitten. It hadn't really been that much of a pleasure experience, it was more of...

...a huge change...

It was a huge change for the little Kitten, an piscin beag. She had been changed overnight by the man she loved from a child into his little woman.

It was a huge change.
