Naked, with her hands handcuffed behind her back and unable to fully stand (since her cuffs were attached to her leg shackles by a short chain), Penny was scared. The room was pitch black, and the house was silent. The light in this room had failed, and nothing else in the house was running, or she'd have been able to hear the hum of their motors. "The power must've gone out! I'd better get to my front porch and retrieve the key to these locks," she told herself. As her main challenge for this bout of self-bondage, she'd placed the key out on her front porch, even though there was snow on the ground. Currently, she was in an upstairs room and on the floor on her side, to keep her wrists near her ankles.
Her fear turned to cursing as she struggled to move through her cluttered room. "Why did the power have to go out now?" she asked rhetorically. "Why did I get myself into this position?" she muttered, trying to slither over some obstacle, which felt like clothing. "OW!" she exclaimed as something - one of her discarded high heels? - dug into the tender flesh of her exposed breast. Rolling sideways to lift her aching flesh off the offending object, she felt even more vulnerable about being bound naked in this darkness. As she continued her arduous journey through this unseen landscape, she reflected how different she felt from about two hours ago.
"I was so bored when this started," she thought. Being cooped up in her house, 'sheltering in place' as they called it, for almost a year was driving her crazy. So she'd turned to self bondage to pass the time in a more exciting manner. Most of the time it worked well. Tying herself up in interesting ways - making herself vulnerable - was exciting. She could struggle, and use her imagination to create scenarios. In these scenarios she could be a helpless hostage, trussed up by her captors. This allowed her to imagine the many things (usually sexual) that they were planning to do with her. The scenes could become real enough in her mind that her pussy would be drooling her pungent juices in a puddle.
Hence, she didn't mind being confined for hours on end, since those hours could be filled with these lewd times of arousal, sometimes even to a climax or two, if she rubbed her body against things. She'd turned to the internet to get ideas about ways to confine herself. "I thought that advice about always having a spare key at hand for emergencies was a good one. Of course, they also advised me not to make it too easy to obtain so I wouldn't be tempted to get it on a whim. But why did I stick my spare key into a glass jar, filled with motor oil, and place it on a shelf in the garage? Sure, I can nudge it off the shelf, or bump the shelf itself to make it fall and break, creating a mess of broken glass and oil. I'd have to carefully search through the resulting mess for the key," she muttered, still inching her way toward what she hoped was the door. The emergency key idea didn't seem so wonderful now that she was in a true emergency.
Her voice became tinged with anger, at what, she wasn't exactly certain. "But getting to the garage from this upstairs room in total darkness is virtually impossible, if I'm having such problems merely leaving this room. And then finding the shelf, breaking the bottle and trying to find that key without having a clue of where to look, with my hands cuffed behind me? Madness!"
Still, the evening had started off as planned. Before it had gotten too dark, she'd gone out onto her front porch and carefully positioned the handcuff key in its usual, accessible spot on the porch floor near the railing uprights. Proceeding to her upstairs room, she placed the key to the small padlock on the floor, against the wall near the door. She'd already eaten, and drank enough water to quench her thirst. Taking care of her bathroom needs, she felt she was ready. Going back into the upstairs room, she carefully shut the door and stripped. Her heart rate sped as she secured the shackles around her ankles. Opened by the same key that unlocked her handcuffs, that single key on the porch could free her completely, once she reached it. The short chain between the shackles meant she'd be hobbled as she walked, and would make going down the steps a slow challenge.
Next, she threaded the small chain through the connector on her handcuffs. This chain would tether her wrists closer to her ankles, held to the shackle chain by a padlock, which she now added and locked closed. All that remained was for her to close the handcuffs on her wrists while they were behind her back. She done this many times before, and had even devised a mirror and a small stud that she could press the handcuffs against to double lock them against tightening too much. With slight rasping sounds and tiny metallic 'snick' sounds, the cuffs were closed and double locked. She had to crouch down to do this, and awkwardly walked over to the far end of the room, to get onto her side on the sofa there.
Then her fantasies kicked in. These were the reasons that her self bondage sessions were so satisfying. In her vivid imagination, things became real enough that her body reacted viscerally. Bound and helpless, one day she might imagine she'd been abducted off the streets, to be held for ransom. She could imagine her kidnapper calling her widowed mother, demanding money. She in turn would demand to speak with her daughter, to see if she was okay. But as the kidnapper held the phone to her ear, he'd grab and toy with her generous 38D tits, making her moan into the phone. As her mother demanded to know what was going on, the kidnapper would start finger-fucking her, and she'd gasp, "He's fucking my pussy with his fingers, and... and... oh my god... Mom... he's also rubbing my clit hard and fast! Aahh! I'm cumming! Oh fuck! I'm cumming!" And she'd blush to think of her mother hearing that, but the scene was really hot!
Another day she might imagine being grabbed by a pervert, and dragged into his van, there to be stripped and trussed up like a turkey. He'd drive her to his remote house, and carry her naked body down into his cellar. There the walls were gleaming white and clinical, because it was his makeshift laboratory. He needed a subject to test the machines he was devising - machines destined to make the female subject orgasm. Not just once... but over and over. Forcing her to cum again and again and again until she slumped unconscious from the intensity of the sensations. And when she regained consciousness, she'd find herself on a different machine, and he'd start testing again, perhaps this time on a machine that could make her climax while only manipulating her generous breasts. She'd never actually experienced electricity applied to her tits, but she could imagine a tingling sensation that increases maddeningly until she's forced to cum. She lost track of how many times just the mental image of this experimentation ordeal had actually made her cum while bound, since she was very skilled at imagining weird, soulless machinery acting on her helpless body.
