Walking through the park, I see a woman sitting on a tree stump and walk over to her.
"Good morning. I just had to stop and tell you how hot you look sitting there, open like that with your leather boots and frilly top. Just too sexy!"
"Well, Thank you. I'm happy to hear you say that."
"Just telling it like I see it as a Yank visiting from the US."
"Well, I appreciate it. I'm Dianne, by the way."
"I have to say, Dianne, you look great! You know, it's a good thing we're not in my hometown. I'm a detective there, and it falls on us cops to enforce an outdated modesty code they have. They're so conservative that they let the code stand, which requires cops like me to check the panties, or I guess you call them knickers, of women who let them be seen by the public. If we were there, I'd have to check your knickers for skimpiness and transparency. Normally we'd take you to the police station, so we'd have privacy, then we'd have you remove your knickers and measure them and get them wet to see if anything shows through them. If they're too skimpy, or if they're too transparent, the code states that we can't let you show them to the world, as you're doing now, and you'd have to wear something that covers better."
"But I like to save women the hassle of going to the station, so with their permission, I just check their knickers where they are and see if they're too small or show anything. Since no one is around, I could show you how I do that, if you like, though without any water here, I'd have to massage your privates to get you, and your knickers wet to check transparency. You could stop me anytime if it bothers you. What do you say?"
"Sure. Why not. I'm just relaxing here."
So, I place the backs of my hands inside your legs and let them drift toward your crotch. You enjoy the feeling on your sensitive inner thighs, so you say nothing. Soon I'm at the edge of your knickers, or where they should be, but I find nothing. I move my fingers to the center where they should cover your privates, but I find only your bare pussy. Again, you say nothing, but you visibly tense for a second and then relax.

The message that you're enjoying my intrusion is clear, so I run a finger up your slit and open you. You let out a sigh, but don't tell me to stop, so I continue to caress your slit, up and down as you spread your legs a bit further. You moan a little as I trace over your tender inner folds, and I find you're getting wet from my finger play. I continue, and now I'm at your clit, which I gently rub before swirling around it. You squirm a little as you sit on the stump and open your legs even further.
Feeling your desire, I add a little more pressure to my swirling while I place a finger at your opening. You lean back a bit and moan again as I press into you. I slide my finger in as far as I can, then add a second finger. You're very wet now, and it's easy to slide in and out of you, so I begin finger-fucking you as I move my hand so that my thumb is now on your clit to continue caressing your sensitive nub. You are squirming on the tree stump now, with your legs spread wide, enjoying what my hands are doing to you. As the moments pass, your entire body is taken over by the feeling emanating from your cunt! You cannot hold back and begin to squirt your feminine juices on my hand, jerking with the spasms of an orgasm. You muffle a scream with your hands as you come, totally consumed by the pleasure I am inflicting on your clit and pussy. You jerk and spasm, and I help you to keep from falling off the stump.
Then, almost as quickly as you became aroused, you're done, spent, exhausted.
As you relax and recover, I give you my handkerchief to clean up, and we straighten your clothes which became disheveled.
You say, "It's too bad I don't live in your hometown... you could check my knickers regularly!"
"Yes, it's too bad!" I answer.
