The pressure - the need - was getting too strong for Rina. Long addicted to self bondage, she felt it'd been too long since she'd really challenged herself. At that moment, her wrists were handcuffed in front of her, and she was looking at her nude body in her bedroom's full length mirror. She saw a woman with dark brown hair, which fell straight to just above her shoulders, framing a face with dark brown eyes, a cute, slightly freckled nose, and slightly pouty lips. Her 38D breasts, with their vertically oval dusky brown areolae peaked by nipples that resembled pink pencil erasers, were framed by her arms. Her mound displayed the discrete triangular trimmed brown carpet that she favored, which left her labia clean and visible.
The handcuffs, which used to be thrilling years ago, when she'd started doing self bondage, were like old friends now - comfortable, but familiar. She needed to do something new with them. She'd been using Google to search for ideas, often stories from other people into self bondage, and images of devices they'd devised.
Reading about things a person could do with a gel cell battery started giving her ideas. She began to plan. Planning the self bondage experience was almost as engaging as actually doing it, because she felt each planning step viscerally, from the shopping to the reconnoitering, scouting for the perfect place.
Weeks later, she felt she was ready, and the weekend weather was going to be perfect.
Early Saturday morning, she drove out to the isolated area she'd selected. She parked her car in a secluded location. "Thank goodness this car has off-road capabilities," she murmured to herself as she climbed out.
First things first. The simple, primitive lean-to shelter that she'd set up the week before was undisturbed. She covered its roof with some fresh leafy branches. It would provide shelter, if the weather changed unexpectedly. She next distributed her food supplies - some in a bowl on the ground, and more dangling on strings from tree branches. She had a bowl of water on the ground, as well, but she expected to drink from water bottles with straws that she wedged in bushes and tree branches. There was no large or dangerous wildlife to speak of in this region, so she had no fear that the food would attract anything.
As a safety measure, she taped a fully charged cell phone at a reasonable height against a tree trunk. She checked its reception, which was fine. She'd practiced, and knew she could power it on with her nose and hit the speed dial button for 911 if an emergency arose. She taped her watch next to it.
Popping open her car trunk, she pulled out the 'backpack' she'd created. It was small. It was more like a modified fanny pack with shoulder straps. When worn on her back, its lower edge didn't quite reach the bottom of her shoulder blades. Inside it was the gel cell battery. Rina'd tested it, and it could deliver its power for about 20 hours total, but its force weakened near the end of its charge. It was connected to a large electromagnet, which was nestled in the bottom of the pack. The only other noticeable thing was a toggle switch that protruded from the bottom of the pack, near its right side.
This toggle looked strange, because Rina had attached a metal tab of steel to the switch, using a 'cold weld' epoxy. She'd also used that same welding epoxy to attach a slightly larger steel disc to the chain links of the pair of steel handcuffs she now pulled out of her car trunk. She placed the keys to the handcuffs on the flat rear floor behind the passenger seat, after moving it forward, to make room in the back. From that same floor, she picked up a small nail, a brad, whose diameter was similar to the double lock tip found on the handcuff keys, and held it between her teeth, before thinking better of it, and placing it carefully on the ground on a bare patch of earth near the trunk.
Leaving the trunk open, she locked her car doors and placed her car keys carefully atop its rear tire on the driver's side. She took a last minute mental inventory. "Is everything in place? Cuff keys - check. Car keys - check. Shelter - check. Food and water - check. Cell phone - check."
It was now about ten am. It was time to begin.
She pulled off her T-shirt, folding it, and placing it on the clean sheet with which she'd lined her trunk. She paused. She'd never stood around, displaying her upper torso dressed with a bra in a quasi-public place like this. She looked around, scanning if anyone was in sight. If she did see someone, which was highly unlikely, she could pretend that she was just changing her clothes. At that point, she wished she'd thought of having a change of clothes stowed in the trunk, to give credence to such a story.
But there was no one about. So, gritting her teeth a little, she stepped out of her shoes, and slid her slacks down her legs. Stepping out of those slacks, and placing them in the trunk, she now stood wearing just a bra and panties. She knew her silky pink set of underwear looked fabulous on her, but still it seemed strange to be standing outdoors wearing only that. "Bra next? Or panties?" she asked herself. Instinctively delaying the exposure of her most intimate area, her hands reached behind her back.
Undoing the bra's hooks, she slipped its straps off her shoulders, coyly holding its front panels in place over her tits. Taking a deep breath, she pulled the material away, and warm air and sunshine kissed her bare breasts. After lowering the bra into the car's trunk, she raised her hands up to her tits, perhaps intending to cover them modestly for a moment. But once her palms covered her areolae and nipples, she began kneading and caressing her sensitive flesh. Her nipples hardened, and her areolae crinkled up with delight, a pleasurable warmth radiating from those locations. As she played with her breasts, Rina knew that if what she'd been planning worked, it would be quite some time before her hands could touch them again.
A spot of moisture appeared at the bottom of her panties, and a familiar scent wafted into her nostrils. Her pussy was reacting, opening and lubricating. She didn't want her panties to get sopping wet, so the appearance of those fluids gave her the impetus to quickly strip them off her body, regardless of being outdoors at the moment. The panties were laid out separately on the trunk's sheet, to let them dry easily.
As the realization hit that she was now completely naked, Rina drew one arm across her chest to cover her breasts, while the hand on her other arm covered her sex, with her thighs pressed together. She might be thrilled about self bondage, but she wasn't an exhibitionist. She had a healthy libido, though, and before long, the hand at her pussy started caressing her delicate folds, and smearing her wetness on them, and eventually her fingers got busy.
She'd never pleasured herself outdoors before, and it felt quite naughty to be doing so. The naughtiness enhanced her arousal in a way that caught her by surprise. Aware that she'd be denying herself orgasmic release very soon, she gave her excitement free rein, and was quickly using both her hands as she fingered her cunt, and stroked and pressed her labia and clit. Her generous breasts bobbed up and down as her torso took on a humping, thrusting action against her hands and fingers.
Her arousal built and built, and normally she'd be howling aloud with excitement. But, not knowing how far her sounds might carry in the open air, she kept her grunts and whimpers at a quiet level. Perversely, having to stifle herself in this manner seemed to build her level of stimulation to a peak she'd seldom experienced. Finally, she had to lean on the car's fender with one hand to support herself, since her legs went weak as her climax crashed through her body.
She was almost out of breath, leaning there, savoring the feel and aroma of her glowing body. Recovering some normalcy after a good five minutes, she wiped the sweat off her body with a towel from the trunk. Once her skin was dry again, she applied a long lasting insect repellent to all her exposed surfaces. "Don't want to be worried about needing to swat bugs," she whispered to herself.
With that accomplished, she slammed the car's trunk shut. Naked, she put on the small backpack, threading her arms through its shoulder straps. The fronts of the shoulder straps had short horizontal straps attached - these ended in the two parts of a plastic side release buckle. She snapped the buckle closed over the center of her sternum, which dragged the shoulder straps close to it, those straps now separating her tits from each other. Somehow, having each breast now thrusting forward through what was actually the armhole of each shoulder strap felt extra lewd to her. She blushed.
Taking the brad from where she'd left it, she held it carefully in her fingers. With her wrists behind her, with practiced ease, she snapped the cuffs onto her left wrist, and then her right. By touch, using the brad, she poked the double locking studs on the cuffs, which would prevent them from closing any more tightly on her wrists, should she happen to roll her weight onto the cuffs.
This was the moment of truth, and Rina's heart was pounding fast in her chest. Adrenaline was pumping through her system, and she was almost panting with a mixture of apprehension and excitement. She felt the hairs on her arms rippling erect in the ingrained 'fight or flight' response of a trapped animal. Because with her wrists secured behind her, she was exposed and helpless. And she was about to make herself even more helpless.
Savoring the sensations, feeling the rush of anticipation, she paused with her finger tip on the toggle switch. She was almost dizzy from hyperventilating, knowing what was going to happen.
