Sexy Fun Times/Work/Social Worker/Baby Smith

When you see where the Smith’s live, you know that there is no way you'll risk parking your car anywhere near their house, so you take out your phone and dial up an Uber. While you’re waiting, you read the case notes.

Sally Smith is a 14-year-old with a three-month-old baby called Mandy. Her parents threw her out so social services found her flat in a tower block which already had a number of other young, unmarried mothers living there. The fact that she actually got one of those flats almost certainly means that somebody on the council is fucking her – probably the father of the baby.

The teenagers hanging around in the entrance eye you up and down but decide that discretion is the better part of valour and you walk past them, suffering nothing more than a few snide comments. Sally is on the fifth floor and the lift doesn’t work, so you walk up and knock on her door. Nothing happened so you knock louder until eventually the door opens to reveal a young girl with a naked baby on her hip. “Who the fuck are you,” she says, aggressively. She's about five foot nothing and surprisingly flat-chested considering the age of the baby - clearly not breast feeding then. She's wearing a towelling robe and her feet are bare, but her toenails are painted bright red.

You show your ID and she scowls but lets you in. Surprisingly, the place is fairly clean and tidy, so much so, that when she offers you a cup of tea you decide that it’ll be safe to accept. You sit down on a rather battered armchair and she goes towards the kitchen. Then she turns around and holds the baby out towards you. “Can you hold her while I make the drinks,” she says. The baby seems unconcerned about being dumped on a strange man’s lap and sits, looking up at you with interest. “I think she likes you,” Sally says when she comes back with the drinks. “Mind, she seems to like men.”

It’s difficult to drink your hot tea with a naked baby wriggling about on your lap and making your cock swell, but Sally seems happy to leave her where she is. Your other problem is that she is laying on her back with her head on your knees and apparently try to suck her toes, which of course gives you an excellent view of her little pussy. Actually, it’s not that little and seems surprisingly well developed. You listen to Sally’s complaints about how hard it is to look after Mandy on her own. Apparently the council promised to find a nursery place so she can go back to school, but she’s heard nothing. You tell her you’ll see what you can do.

Much as you are enjoying the view, you’re beginning to think it’s time you left, when Sally suddenly stands up. “I need to do some shopping, but I can’t drag her pushchair all the way up and down those fucking stairs. It won’t take long, so can you just stay and keep an eye on her?”

Your first instinct is to say no, but then you have another look at that little baby cunt and change your mind. “I shouldn’t really, but I guess I could spare an hour,” you say. She goes into the bedroom to change, but leaves the door open, so you get a good view of her shapely bum. Her skimpy underwear does little to cover anything up and it looks pretty uncomfortable. As she steps into a dress and pulls it up without bothering with a bra, you have to adjust your cock.

Minutes later, she’s got her coat on and she’s out of the door leaving you with a naked baby on your lap. “Well Mandy. Do you think your mum knows that she’s left her baby with a paedophile?” Mandy doesn’t reply, but she reaches down to give her pussy a rub. “Would like me to do that,” you ask. Taking her lack of reply as a “yes”, you suck a finger to make it wet and stroke it up and down her slit. She wriggles a bit, but clearly doesn’t mind you taking liberties. You’re about to suck your finger again, but change your mind and reach up to push it into Mandy’s mouth. She immediately starts sucking and licking and you can’t help imagining how it will feel on the end of your cock. You take your wet finger, slide between the lips of her pussy and try an experimental probe into her vagina. There is no hymen to bar access, although not all girls are born with one, and you are able to get your finger in as far as the first knuckle.

You wonder how far you dare go, because you have no real idea how long it’ll be before Sally gets back, and you have no idea what her reaction would be if she caught you diddling her baby.

• It's too risky
• There's surely enough time for you to relieve the pressure before she gets back
• Fuck it. What did she expect?
