Ronnie is cute. You haven't really noticed her before, but it's hard to believe that she is her mother's daughter. Her hair is a cloud of golden curls which, according to Emily, are a real pain, being prone to tangles. She has big brown eyes like a puppy and the same sort of energy. When you arrive, Emily has just got her out of the bath and she is wrapped in a big fluffy towel.

"You're early," she says, laying Ronnie out on the couch and going to work on the wriggling, giggling girl to get her dry.

"Sorry, would you like me to come back later," you say, although according to your watch you are right on time.

She laughs and blows a raspberry on the naked toddler's belly. "Nah, it won't take a minute to get her into bed. There is Coke in the fridge if you want some."

You sit on the armchair, sipping Coke out of the can, while she gets Ronnie ready for bed. Watch her a minute will you," she says, and without waiting for a reply she goes out of the room into what you assume is Ronnie's bedroom. Ronnie is laying naked on the towel, doing her best to suck her toe and you have a clear view of her little baby pussy.

You can't help looking at it; it's the first one you've ever seen in real life and it doesn't look all that much like the ones in the pictures. It hasn't got any hair for a start. She loses interest in her big toe and then reaches down to rub between her legs and you wonder if it feels good for her like rubbing your cock does for you.

"Sorry about that," Emily says as she comes back in carrying some pyjamas. She doesn't seem at all concerned that Ronnie is rubbing herself and sits her up to get her arms into the sleeves of the pyjama top. Ronnie wriggles about trying to get away and Emily nearly drops her. She finally gets the top on but then she lifts the half-naked toddler up, carries her across the room and drops her on your lap. "Just hold her for a minute will you while I get these pyjamas on," she says.

Having a half-naked baby wriggling about on your lap gives you an erection and when she lifts Ronnie back up again your relieved she doesn't seem to have noticed. "Right young lady, let's get you into bed," she says and carries Ronnie into the bedroom. You're still sitting in the armchair, wondering where the TV remote is when you hear her voice through the door asking if you can read her a story while she gets changed.

"You need to sit beside her so she can see the pictures," Emily says and you sit down on the side of the bed with the book she gives you. It's one you're familiar with although you haven't looked at it for a long time. She snuggles up beside you and you have to put your arm around her to hold the book across both your laps. The Hungry Caterpillar eats its way through various fruits and vegetables before it gets the ice cream and chocolate cake and by the time it turns into a butterfly, Emily comes back.

Instead of her usual black outfit, she's wearing blue jeans and a white T-shirt with "Girl Power" on the front. "What do you think, I haven't worn these jeans for ages and I think they're a bit tight.

"They look fine to me," you mumble. They really quite stretched across her bum and the way her cheeks move underneath is making your cock swell up again for some reason. You stand up while she tucks Ronnie into her bed, gives her a kiss and tells her to be good for "Uncle" Jason.

You go back into the sitting room and she turns TV on. "Give her half an hour and she will be fast asleep," she says. The news is full of death and disaster as usual, so she clicks around trying to find something different, ending up with an old rerun of The Simpsons. When it's finished she goes over to the bedroom door, put her finger to her lips to tell you to be quiet and opens it just a crack to peek in. Satisfied that Ronnie's asleep, you make sure you've got her phone number and leaves you to fend for yourself.

• Left in charge, you have a pretty uneventful evening
