Anna couldn't help but shiver, even though it was warm outside. The streetlights illuminated her path, her bare feet slapping against the sidewalk. She'd taken her brother's jacket, glad he was out of town for the weekend so she didn't have to come up with an excuse for needing it in the middle of June.
The borrowed jacket wasn't too thick, but the inside was lined with some sort of fake fur. Perfect for keeping warm in the winter, and in this case, for keeping her bare body hidden from any passerby.
She grinned again, stunned at what she was doing. She'd left all her clothes sitting on her bed, the only thing covering her the jacket, which fortunately went down to her knees since she was a good bit shorter than her brother.
With every step, her thighs rubbed together, and she had to force herself not to slip a hand inside the coat to run a finger along her soaked slit. A car passed by occasionally, but she hadn't seen anyone on the sidewalk since she left the house.
Anna stopped at the entrance to the park, turning right. A large metal gate had been swung shut and locked, to keep out unruly teens who had kept getting caught in the middle of the night vandalizing. The gate was held on either side by two concrete pillars, and each pillar had hedges bordering them. The hedges continued down the sidewalk a ways, and a tall metal fence could be seen sticking out of the top.
Ducking down to the left side of the fence before any cars could pass by and see her, she pushed some of the hedge aside to reveal a small hole in the fence. She had heard rumors about the hole from a friend, and had been glad to find out it was true on her last night trip here.
Taking a deep breath, Anna got on her hands and knees and crawled into the hole. Her jacket was buttoned shut, but the warm night air still slipped through it and blowing against her naked skin. She stopped and covered her mouth to avoid her moan floating through the vacant park.
After a moment, she continued crawling, pulling herself through on the other side of the fence. She stood up and brushed some dirt off her knees, and wiped her hands on the jacker. She'd have plenty of time to wash it before her brother noticed.
Standing there in the dark, the park lights off, she mentally prepared herself for the next part of her plan. She'd spent several days studying the park, making sure there were no cameras around that could catch sight of her.
Taking a deep breath, she unbuttoned the jacket, letting it fall to the ground. She stood there, instinctively covering her tits and crotch with her arms, before letting them fall to her sides. She kicked the jacket back to the hole, leaving it hidden. Facing the park, she started her walk.
She walked slowly along the paved path, letting the night air blow against her body. She knew she was leaving a small trail of her own juices behind her, which lad long ago run down her leg while she was walking.
The park wasn't very big, so she reached the little pavilion at the center quickly. There was a roof covering a few picnic tables, and a small building which held public restrooms. She forced herself to keep her arms from covering herself, and went for the bathrooms.
The walk to the park had been exciting. The shorter walk through the park without the jacket had been even more heart racing. But this part was the only one she was actually afraid to go through with. Grabbing the doorknob of the women's bathroom, she went inside.
The room was pitch black, and the faint moonlight from outside disappeared as the door shut behind her. From here, she had to rely on memory. She went to her right and put her hands out until she felt the wall of a stall. She followed it to the second door, which she pushed open. Inside the stall, she tentatively lifted her foot up until she found the toilet.
Cautiously, she stepped up onto the toilet and steadied herself. Reaching up, she was able to put a hand up above the beams that ran along the roof in place of a solid ceiling. Her heart raced, afraid it had been stolen, but she let out a sigh of relief as her fingers brushed the small silk bag.
The friend who had dared her to go through with this whole thing had promised she'd left the bag there, but refused to say what was inside it. Pulling the bag down, she sat down on the toilet, grimacing at the sudden cold of the porcelain against her ass. She fumbled with the tied strings of the bag in the dark, but managed to open it and felt around.
The first thing she felt she could clearly tell what it was. She grasped the smooth ball and pulled it out, the straps dangling off the side. Anna couldn't believe her friend had actually left her a gag, but that disbelief didn't stop her from setting the bag in her lap and opening her jaw enough to fit the ball in.
She reached around her head to click the latch of the gag in place, tightening it. Reaching back into the bag, she found the second item and she would have grinned if she could. She removed a pair of nipple clamps, held together by a thing chain.
She set the bag back down, knowing what the weight inside was, and clamped the little metal toys on. She yelped as the first clamp bit lightly into her hardened nipple, the noise muffled by the gag, and the second clamp made her yelp again.
She sat there, gagged and clamped, her heavy breathing loud to her ears in the darkness. She sat there for a few minutes, letting her right hand play with her slit while her left hand occasionally tugged on the chain of the clamps, making herself jump every time she yanked.
Finally, she picked the bag back up and pulled out the final toy. She recognized the shape of the vibrator against her palms, knowing it was the one she'd lost to her friend in a game of strip poker. Leaning back against the toilet, she spread her legs and pressed the tip of her familiar friend to her soaked opening.
She couldn't wait, slamming the toy in up to it's base. The 8 inches made her scream into her gag, the rubber balls slapping against her skin. She spasmed in her seat, cumming instantly. All the buildup from the walk and the other toys had brought her to the edge, and the toy suddenly filling her had pushed her over the edge.
Her gag kept her from screaming, and she sat there twitching as her orgasm rolled through her. Slowly, she came down from her high, and gripped the base of the dildo. Her fingers quickly found the switch on the flat base of the balls, and she flipped it to the low setting.
She groaned as it started buzzing inside her, and she slowly pumped it in and out, quickly bringing herself to a second orgasm, this time the gag barely keeping her screams at a safe volume. As she came, she felt herself tilt to the side.
She threw her arms out as she fell sideways off the toilet, not realizing her cumming and thrashing had distracted her from the fact that she had slowly slipped off the seat. She didn't hit the ground too hard, but it was enough of a shock snap her out of her trance realize she had been here longer than she should have.
