At a park, with an invitation

You cruise, looking for a likely spot, but conscious that you don't want to take too long finding one. You spot what appears to be an open space as you cross a side street, and making a quick turn discover a public park. You park your vehicle and douse the lights, rolling a window down so you can listen and watch. You can see a few covered picnic tables a short distance away, and dimly make out some odd shapes in the darkness a little further. As your eyes get used to the darkness, the shapes resolve into a children's playground.

Thinking, you pull Amber's phone out of your pocket. She has no password protection, and it opens with a single swipe across the face. You click on her contacts and scroll down, not entirely sure what you're looking for, an idea starting to form in your mind. You finger stops on a contact listed as 'Creeper Eric' and when you press on the message history you find a series of texts between them. Eric has sent Amber several messages full of sexual innuendo to which she has responded with teasing disgust. It doesn't seem to have discouraged him, however, and he's sent her several dick pics, none of which show much in the way of length or girth, and to each of which she has responded with mockery.

You smile to yourself as you get out of the vehicle and lift Amber's wrapped body out of the back seat. She squirms, and there is a muffled moan from her, but you sling her over your shoulder and grab her backpack and the garbage bag.

Moving carefully, your ears pricked for any sound, you carry her to one of the picnic tables and unwrap the blanket. You cut the tape away from her mouth, and she gives a gasp, then mumbles incoherently. The vodka you poured down her has done it's work, but just to make sure you feed her a little more. You cut the ties on her ankles, spreading her legs and retying them to the table supports, leaving her splayed open, her pussy displayed.

"You're going to have a great night, slut," you chuckle as you free her wrists then rebind them in front of her. She murmurs drunkenly, squirming purposelessly on the table. You open her phone and send a message to 'Creeper Eric' as you smile cruelly down at the helpless girl.

"Hey! I'm DTF! Into some kinky shit. Come find me @ the park! Bring friends if u want! More cocks the better! I got vodka and I'm wet and waiting!" You press send, then start to scatter her backpack and torn clothes around the table.

Her phone chimes with a response and you open it to read Eric's reply. "WTF? You playin with me? Serious?"

Grinning, you pull Amber's bound hands down to her pussy and take a close up, carefully keeping your own hands out of frame. Adding "Serious AF! Get here!" you send the picture back as a reply before continuing to set the scene.

"Holy Fuck! OMW!" Eric responds, as you survey your handiwork, leaving the nearly empty vodka bottle and her cellphone beside her before heading back to your vehicle.
