Sexy Fun Times/Laid/Park/Frame
You walk over and sit next to the young woman with the kids; she briefly looks up from her phone and then goes back to whatever game it is she's playing. You pull your own phone out and make out you are checking emails, while you are really watching the kids.
After a few minutes, there's a loud yell, and when you look up you see that one of the children has fallen out of the climbing frame. The woman sighs, puts her phone away, goes over to the little girl who is sitting on the ground bawling and picks her up. "Where does it hurt," she asks as she sits back down and wipes the snot and tears off the child's face.
The girl points at her belly and the woman stands her up and pulls her shorts down to have a look. She's got her back to you you can't help thinking what a cute little butt she has; barely covered by skimpy pair of panties. It seems that the girl meant a bit lower down, so, ignoring you, the woman turns her around and pulls her panties down to check her pussy. By this time the girl has stopped crying and started giggling and the little boy has come over to see what's happening.
When the woman puts the girl back on the ground and pulls her shorts up, the little boy gives her a sympathetic hug. "Cute aren't they," the woman says, looking across at you and then down the bulge in your pants.
You shrug. "Very; are they yours?"
She laughs. "Nah; I just look after them during the day."
Over the next few minutes, you discover that her name is Susan, she's nineteen and she is a student; the kids are brother and sister, Alice aged five and George a year younger. They live in a big house overlooking the park and Susan is a kind of live-in nanny. "They're good kids, but it gets pretty boring with just them for company; it's nice to talk to a grown-up for a change," she says.
"I need a wee," George says.
"Me too," says Alice.
"I'm hungry," Alice says.
Susan starts to pack up their stuff; they have a twin buggy where they sit facing each other and she takes their sandals off before sitting them in. There is some giggling and a squeal; when you look, you see that George has got his foot right up between his sister's legs, pressing against her pussy. Susan looks down at the kids and then smiles at you.
