Sexy Fun Times/Three/Girl/Colin

You sit on the bench, swinging your legs and watching Colin mow the grass. He moved in next door a while ago, with his mummy and daddy and you haven't had much to do with him until Mummy asked him to do some odd jobs for her. It's a hot day and he has taken his shirt off, exposing his skinny body to the sun. It's not a very big lawn so it isn't long before he empties the mower and coils the long wire up, before putting it back in the shed.

"I bought you cake and a drink," Mummy says, putting two glasses and two paper plates with slices of her home made cake on the little table. "Will you be okay out here for a while. I have some phone calls to make?"

"Of course. Thank you very much," Colin says as he sits down beside you. His legs are long enough so his feet are on the ground.

"You're very skinny," you say.

He looks down at his bony knees, sticking out of the legs of his shorts and shrugs. ""I was sick, but I'm better now," he says.

"Do you play with yourself a lot," you ask.

He nearly chokes on a mouthful of cake. "What do you mean?"

"I've seen you through the fence." There are loads of holes you can look through and you've seen him in his garden stroking his stiff willy.

"That's rude - spying on people." He has gone beetroot red and takes a big glug of his drink.

"It's okay. I play with myself all the time."

"How do girls play with themselves?"

You shrug. "I just rub my winkle. There's a bump at the top that gives the best feeling."

We sit for a while, saying nothing. Then; "I never saw a girls winkle," he says.

"I'll show you mine if you want, but only if you show me yours."

He looks around. "If anyone saw, we'd get in trouble."

"Mummy's in the kitchen. She can't see us from there."

He hooks his thumbs in the top of his shorts and pulls them down so you can see his stiff willy. Of course, it's nowhere near as big as the man in the park's but you like it better somehow. He wraps his hand around the shaft and strokes the loose skin up and down a few times, then he lets his shorts back up to hide it. "Your turn," he says with a grin.

You lift your legs up so your feet are flat on the seat and spread your knees apart. You left your pants off this morning, so when he sits on the grass in front of you, he has a clear view of your winkle.

"It's bigger than I expected," he says. You look at him, puzzled. "I mean, cos you are only a little girl," he stutters. "Can I touch it?"

You nod, and he reaches out to stroke a finger down your slit. It feels kind of tingly and makes you shiver. He takes his hand away. "Are you okay?"

"It, err, tickles," you say, not knowing a better description of the feeling.

"Is mine the first cock you've seen," he asks.

Cock. That's a new word, but you guess what it means. "Not really. I saw Harry's, but he's only little like me. Then there was the man in the park. His was big." He asks about the man in the park and you tell him how he poked it through the wall and it nearly went in your mouth. "Why did he do that," you ask.

"It's something grownups do. I've seen pictures."

"Do you want me to suck yours?"

"I guess. Would you?"

You shrug and he gets back up on the bench. There's still no sign of Mummy, so he pulls his willy - no, his cock out again. You stand up in front of him and he holds it while you open your mouth and suck it in. It doesn't taste of much, but it feels strange in your mouth, and you lick the end. Suddenly, he pushes you away and you think you must have done something, but he says sorry. "It was too much. I nearly cummed," he says.

"What's cummed?"

"It's the real great feeling you get when you finish," he says and you can see he's gone red.

"Did you have fun with Colin," Mummy asks later.

"Yes Mummy, he's nice." Somehow you don't think she's asking about the cock-sucking thing.

"His mummy worries about him after he spent such a long time in hospital. She thinks he needs to get out more. Now the holidays have started, would you mind if he spent more time here with us?"

You shrug, but wonder what naughty games you will be able to play.

"I'll take that as a yes then," Mummy says with a laugh, and she picks you up for a cuddle.
