Rina was driving back to the same isolated area where she'd had the adventure with the gel pack battery and electromagnet. This time, she expected her self bondage session to be less strenuous, and of shorter duration. But what she had in mind was still exciting, because she'd be doing it outdoors once again.
Her excitement was manifest by the fact that she had the foresight to fold up the towel and place it under herself as she sat in the driver's seat. A silky red set of bra and panties were on the backseat of the car. Rina didn't expect to need them at all. They were merely there as a precaution.
Her 38D breasts, unrestrained inside of her blouse, swayed and jiggled with each bounce of the car on the road. This caused her nipples to rub and rub against the soft material of her blouse. That delightfully maddening friction increased her arousal, and her pussy was lubricating well in response. This might have ruined her skirt, but she'd hiked her skirt up around her waist as she drove, thereby letting her leaking pussy make direct contact with the towel beneath her.
She had her car windows closed, and the aroma of her cunt juices permeated the air around her. As she inhaled her scent, it acted like a positive feedback loop, increasing her arousal, which, of course, made her lubricate even more. By the time she neared her destination, she feared she might've needed to have two towels under her, rather than one. She certainly would need to take a long drink of water to replenish the fluids her body had generated and lost into the towel.
Using her cars off-road capabilities as before, she pulled in to a similar secluded location. She drank a good bit of water, as she'd promised herself. With a hair tie, she pulled her dark brown hair into a neat ponytail, before climbing out of her car.
Should she strip off here at the car? Or wait until she got to the meadow? Walking all the way there naked still seemed so naughty a thing to do. But she'd been naked the last time, and she had to admit, although it felt strange at first, it became quite natural after a very short period of time. She suspected she had a healthy streak of exhibitionism, but was loath to admit that to herself yet. She rationalized it, though. "If I leave my clothes here at the car, that's one less thing to carry," she told herself.
Indeed, she found that stripping 'in public' was much easier this time. Unlike the last time, this time she pulled off her skirt first, yanking it down. A stray breeze washed over her damp sex, evaporating some of her juices, and giving the tissues there a cool 'kiss' sensation. Playfully, she pressed her labia open, and let the air play with her entire vulva. What a glorious feeling!
Her hands went to her blouse, unbuttoning it down her front. She imagined being on some stage, opening her blouse before a group of men whose eyes were riveted to her chest. When the blouse was fully unbuttoned, she playfully flipped one side off her tit, and then flipped it back, as if teasing her onlookers. She blushed as she realized that she enjoyed that image, and wished she had enough courage to really do such a thing. "Yeah, yeah - I'm just a big chicken," she berated herself gently. Sighing, she slipped off the blouse, and placed her clothes in the car's trunk.
As she'd done before, she applied insect repellent to her exposed skin. She was happy how well this stuff worked. Not even a mosquito bite last time. Reaching back into the trunk, she pulled out a medium-sized metal cooler, along with a small cloth bag. Locking up the car, she put the car keys on top of the rear tire on the driver's side, just like last time.
She started her stroll to the meadow, almost bouncing with happiness and anticipation. There was something extra special about performing self bondage outdoors. She didn't know why she'd waited this long to try it. She noticed that there was more of a breeze today, and the sky was overcast, even though it was still nice and warm. The breeze made her skin rise up in goosebumps. Her nipples couldn't be mistaken for goosebumps, but they expanded, poking forward in an amazing fashion. Both her hands were busy carrying things, or she'd have been playing with them.
After a few more steps, though, she thought to herself, "Hey! Am I in a rush or something? My nipples feel like they could pop, they're so swollen!" With that, she set down the cooler and the bag and stood, playing with her nipples for a while. It felt wonderful to pinch them and tug them, and soon her hips were making gentle bucking motions as she squirmed. Once again, rationalization sprang up. "I won't be able to make myself cum for hours, in a few minutes. Why waste this opportunity?"
Still playing with her tits with one hand, she used her other to probe her cunt, pulling out her sticky liquids, and smearing them on her labia edges and clit. Looking around instinctively, she even smeared some juice on her butt hole, and teased that forbidden opening with her wet finger. As her arousal built, she caressed all of her generous tit flesh, as well as her tummy, mound, and thighs, still fingering her cunt. Finally, she jammed three fingers into her hot, greedy tunnel, while polishing her clit rapidly with a finger of her other hand! The resultant orgasm turned her knees to jelly, and she sank down onto the grass, shaking and panting with pleasure waves.
As she got back up onto her shaky legs, she murmured, "Being naked outdoors is making me even more horny than usual. Must be all this fresh air." She took an extra deep breath, and her tits rose as her chest expanded. "Down girls," she giggled.
At the meadow, she saw what she'd noticed during her previous excursion. Near its edge was a smooth wooden railing or fence. She had no idea why it was there, but its height appeared to be ideal for her purpose.
She went to the far end, and leaned over the wooden crossbar. Years of yoga practice had made Rina supple. She could easily bend over with her legs straight and press her palms to the floor in her home. Here, bending over the railing, she found that it pressed right across her lower abdomen, and her wrists easily grasped her ankles. Perfect. It might have been specially built for a person of her height.
Opening the cooler, she pulled out a block of ice with a very sturdy string hanging out of it. That string was tightly secured to a handcuff key, which was embedded in the center of the ice block. She tied the string to the railing, with the ice hanging just above the low grass. Again she bent herself over the railing, verifying that the height of the ice was where she'd want it.
Leaving the cooler off to the side, she took the cloth bag back to the other end of the railing. From that bag she pulled out not one, but two sets of handcuffs, and her trusty brad nail. She stooped down and carefully ratcheted the cuffs to a fit that was snug, but not tight, one on each ankle, and double locked them with the brad.
Relishing the moment, she paused and looked at the railing, the ice, the meadow, and the woods surrounding the meadow. The breeze flipped her ponytail around, making it brush sensuously against the nape of her neck. That same current of air even ruffled the short brown pubic hairs that adorned her mound. After several deep breaths, she was ready.
Rina folded herself over the railing again. Leaning down, she attached the cuff at her left ankle to her left wrist. The moment she did that, she was committed to this adventure. A frisson of delight coursed through her body. Getting more excited, she secured her right wrist to the cuff on her right ankle. For safety, she double locked them with the brad as well.
Now she was stuck like this until the ice melted.
Not only that, she'd have to work her way laboriously down the railing, inch by inch, shuffling along, to reach it. This would certainly take hours.
At first, she just rested where she was, enjoying the feeling of being restrained like this. In a mental image, she saw her bare ass, thighs, and shapely calves exposed on one side of the railing. On the other, her tits were pressed against her knees as she stared at her shins. Her ponytail dangled off the back of her head, nearly touching the grass. The railing actually gave her some support, so she doubted that her muscles would fatigue very much.
Turning her head, she looked at the block of ice. From this distance, she couldn't tell if it was even starting to drip yet. Similar blocks of ice, in the past, had taken about 4 hours to melt fully, so she was in no rush to start moving toward it.
After perhaps 10 minutes of her confinement, her mind started the typical 'what if' and 'worst case' scenarios that made self bondage such a thrill for Rina. Of course, there was the thought, "What if someone stumbles upon my car? Will they find the keys? Drive off with it? Or, what is more likely, will they start calling out and searching for the driver?" The last time, none of that had happened, so these thoughts were less intrusive than they'd been. She trusted that the car would be unmolested. She relaxed as much as she could.
Five minutes later, the sun briefly broke through the cloud cover, and shone brightly on her ass cheeks. She'd neglected to put on any sun block, and sincerely hoped she wouldn't end up with a sunburn on her exposed butt and sex region. That might be difficult to explain. The clouds churned and returned, so the perceived heat of the sun was only apparent during brief gaps in the cloud cover. But Rina knew that exposed skin could even receive a burn through cloud cover, anyway. Yet another thing she'd have to take into account during future outdoor sessions.
About fifteen minutes later, she mumbled, "Oh drat! I was going to call Suzie and tell her what I was doing, and where, with the idea to come and look for me if she hadn't heard from me in... let's say eight hours. But I forgot! And my phone is now locked in the car. I hope I don't regret neglecting to do that. Her heart started thumping hard, imagining being stuck like this. She had to breathe faster, lest she get dizzy. She forced herself to calm down. The ice block 'timer' had never failed her before.
To escape these worries, Rina went into a special state of mind. She'd heard of submissives entering something often called 'subspace' when having a session with their Masters, but she didn't know if that was what she did during her self bondage sessions. Perhaps her mind was going into an alpha state - conscious but unfocused - when she lapsed into this mindset. It was better than fretting about something going wrong, and her being trapped like this, and ultimately being discovered.
Being discovered. That triggered a whole new type of reverie. With her very healthy libido, Rina often fantasized that her restraints were due to the actions of captors. They might be pirates, or robbers, or men that kidnapped women and enslaved them - really, any sort of lusty males. And of course these males had sex on their minds. Sex with her, as she was rendered helpless and vulnerable.
Rina seized on this mental scenario now. Maybe the men were outlaw desperadoes, and they'd robbed a train or a stagecoach. Finding a delectable female traveling alone, they'd grabbed her, and taken her away with them. This railing might be a hitching post outside their cabin, and they'd secured her there until they played cards to see who won the right to be the first to use her sexually. She could beg them... plead with them... to let her go, but their lust would have to be satisfied.
