"Best way is with you on top," you say. You get Peter to lay on his back on the rug, holding his cock so it points up. "Are you good and wet," you ask.

Carol giggles. "I'll get him to give me a lick to make sure." She kneels astride her brother and shuffles forward until her pussy is over his mouth.

"You gotta let him breathe," you say.

She looks round and grins. "He can't talk when he's got his tongue in my cunt," she says.

Oddly. hearing a young girl using the 'C' word is a surprise, even when she is sitting on her kid brother's face. She lifts up and her red-faced brother gasps for air. "Hold your cock up," you say. His chest is still heaving, but his face seems to have gone back to the normal colour as he reaches for his cock. It's at least three inches long and as thick as your finger. "Go on then Carol, don't keep The boy waiting."

She looked round at you and grins, then she kneels astride his hips and lowers herself down onto his cock. The whole thing slides in without any apparent difficulty and, judging from the expression on the boys face, he certainly seems to be enjoying the feeling. Carol starts to lift up and down and it slips out a couple of times when she misjudges how high she can go, but she soon gets the hang of it and starts bouncing happily up and down.

It doesn't take long before he goes rigid, grabs her hips and thrusts as hard as he can before flopping back. Carol looks disappointed, but when she looks round and sees that you got your cock out, she brightens up. You stretch out on your back and hold your seven-inch cock pointing up. "Not too big for you is it," you say. Peter sits up and watches as his sister stands over you. "Come and hold it for me Peter," you say.

He crawls over in his hands and knees and wraps his hand around the shaft of your cock as his sister lowers herself down until the head is splitting her labia. She stops there and you can see her tongue poking out as she concentrates. Then, with a kind of moaning noise, she lowers herself down and your cock is being gripped in one of the tightest little cunts you have ever experienced.

She can't quite take the whole thing, but a great deal of it is buried inside before you feel it bottom out. Her eyes are closed and she's breathing through her mouth. You watched for a few moments as she lifts herself up and down, then you have an idea. "Turn round," you order. She looks at you with a frown, not understanding. "Reverse cowgirl it's called. Just spin yourself around until you got your back to me." Understanding dawns on her face and she hitches herself around. "Now bend forward and bring your knees back," you say. This position gives you an excellent view of her bum. It also gives her more freedom to bounce up and down.

"I can see her poop hole," Peter says. He's moved round to sit beside you and is obviously enjoying the sight of his sister bouncing up and down on my pole.

"Do you think I can get my cock in there," you ask.

He shakes his head. "Nah, too big," he says. "I spec' I could get mine in." His cock is stiff again.

"Maybe another time." Carol has stopped bouncing and has fallen forward while her cunt does its best to milk the spunk out of your cock. You think of all those millions of little sperm wriggling about inside her and have a horrible thought. "You are on the pill aren't you," you say.

"I've been on the pill since I had my first period," she says. "I had to convince the doctor that I was sexually active though."
