Penny had always been curious by nature, a trait that had gotten her into tight situations on more than on occasion during her 16 years on the planet. But the day she stumbled across the black nylon overnight bag tucked away in the back corner of his closet while getting a pair of shoes for him that he had asked for, she let her curiosity get her into a very tight situation, tighter than anything she could have ever imagined.
“Huh, I wonder what’s in there?” she said to herself as she looked at the bag sitting in the back corner on the floor of her father’s closet. She took a quick look around, then grabbed the bag and pulled it out. She set it down on the floor and opened it up, looking inside to see what was there.
“What the hell is this?” she said to herself, reaching inside the bag and taking out a heavy but supple black leather strap that had been rolled up, secured with a rubber band to keep it from unrolling. It was about two inches wide with a chrome buckle, and if she had to guess as to how long it was she would have guessed it was about 6 feet long at least. She looked into the bag and saw another one just like it, along with four other rolls that were the same width but were smaller when rolled up. And out of those four rolls, two of them were even smaller.
“What the fuck?” she said to herself, picking up one of the smaller rolls with her other hand, looking from one roll to the other for a moment or two while trying to figure out what they were for. She looked into the bag again, and when she saw what else was in there she suddenly knew what the straps were for.
“Oh, you’ve got to be kidding me!” she said, dropping the two rolls back into the bag and reaching in to pull out the other thing that she had seen. She was grinning from ear to ear as she pulled out a pair of black leather cuffs bondage cuffs that were the same width as the straps, with two small chrome buckles on each to fasten them closed. They were joined together by a chrome snap link that clinked when she picked them up.
“My father is into bondage!” she said, grinning as she held the cuffs up in front of her face. They were obviously well-used, as the chrome was chipping off in a few places and the leather was very supple. Her eyes went wide when the obvious thought struck her.
“I wonder if he uses these on Mommy?” she asked herself, already suspecting that she knew the answer.
“Penny! Did you get lost up there or what?” her father, Arlen, called from downstairs.
“I’m coming, Daddy!” she called out, quickly putting the cuffs back into the back and zipping it closed, then putting it back where she found it. Then she got the shoes she was sent there to get in the first place, closed the closet and scampered downstairs, trying hard to suppress a grin when she gave the shoes to her father.
As she lay in bed that night, she couldn’t get the image of her father binding her mother up in the straps she had found in his closet. The last thing in the world she would have expected was for her parents to be into that kind of thing; she knew they had sex, of course, but this was something totally unexpected.
And to her surprise, the more she thought about her father using those straps on her mother, the more she wanted him to use them on her. And the more she thought about that, the wetter her pussy got. She ran a hand up under her nightgown and discovered that her nipples were hard as rocks, and when she slid her other hand down into her panties she found that her pussy was soaking wet. She rubbed her pussy and pulled on her nipple at the same time, sending little shock waves of pleasure through her young body. She rubbed and pulled harder, and in less than a minute she had a shattering orgasm, so strong that it shook her whole body and she had to bite her bottom lip to keep from crying out. When it was over she was left panting for breath, with just one thought running through her head.
“I have got to get my daddy to use those straps on me!” she said to herself, grinning in the darkness of her room. All she had to do was wait for the right time, she knew, and she was pretty sure she could get her father to do it.
Two days later the time was right. It was Saturday afternoon, her mom Shelly and her brother, Curt, were both out of the house and wouldn’t be back for hours, so now was her chance. She went looking for her father and found him in the living room sitting in his chair, watching a movie on one of the streaming services. She sat on the couch next to the chair, crossing her legs and smiling as she looked over at him. She was in her usual attire of a form-fitting white cotton short sleeve blouse and a pair of equally form-fitting gym shorts, pink with white trim. She was wearing a bra only because her mother made her; if not for that she wouldn’t be wearing one at all as she hated them because they were so uncomfortable, preferring to let her ‘C’ cup breasts be free of restraint beneath her top. She was wearing a pair of pink thong panties under her shorts, with a pair of sandals on her feet. Her blonde hair was tied up in a ponytail high on the back of her head, held in place by a pink hair tie.
“Hi, Daddy! Whatcha doin?” she asked, her blue eyes sparkling as she looked over at him with a big smile on her face.
“Oh, just sitting here relaxing, that’s all. You?” he asked, looking over at her and smiling.
“Nothing, just taking it easy,” she replied, falling silent for a few moments, not quite sure of how to bring the subject up. Finally she decided to just be direct and ask, figuring that the worst that could happen was that her father would refuse to talk about it, so she did.
“Daddy, can I ask you about something?” she said, looking over at him as she sat with her legs crossed and her hands in her lap.
“Sure, Penny, what’s up?” he replied, looking over at her.
“What’s with the black bag in your closet? The one with all those straps in it, I mean,” she said. The look on her father’s face told her two things: first, that he was surprised as hell that she knew about the bag, and second, that he wasn’t mad. That was good if she was going to get her father to use the straps on her, which she desperately wanted to happen.
“You’ve been snooping in my closet, I see,” he said, a little irked but not much.
“No, Daddy, not really. I found it when I was looking for your shoes like you asked me to a few days ago, and when I saw it I got curious – you know how curious about things I am – so I opened it up and looked inside,” she explained. “I wasn’t snooping; not really, anyway,” she said.
“Okay, I believe you,” he said, nodding.
“Soooo ... what’s with the straps and the cuffs, Daddy?” she asked, trying not to smile. “Are they what I think they are?” she asked.
“I don’t know; what do you think they are?” Arlen asked, trying to find a way out of the conversation without revealing anything to her.
“Well, I think ... I think they’re bondage stuff. Is that right, Daddy? Is that what they are? Bondage stuff?” she asked, her heart pounding in her chest.
‘Moment of truth!’ she thought to herself as her father hesitated for a moment before answering.
‘Shit! Might as well tell her the truth, she’s got it all figure out anyway,’ Arlen thought to himself as he looked over at her.
“Yes, Penny, that’s what they are,” he replied. “Bondage straps and a pair of bondage cuffs,” he said.
“And you use them on Mommy?” she asked. Arlen almost didn’t answer, but he did for the same reason as before – she obviously already had it all figured out in that curious little head of hers.
“Yes, I use them on your mother,” he said.
“And she likes it?” Penny asked, her eyebrows going up.
“I wouldn’t do it if she didn’t,” her father replied.
“And do you like it, Daddy? I mean, using them on Mommy, that is,” she asked. Before he answered Arlen picked up the remote to the TV and turned it off, then put the remote on the table next to his chair. He clasped his hands in his lap and looked at Penny, a serious look on his face as he spoke.
“Before I answer that, I have to know that you’re not going to mention this conversation to anyone, ever. Not to your mom, not to your brother, not to your best girlfriend, not to anyone. What your mother and I do in the privacy of our bedroom is nobody’s business. Bondage is widely misunderstood by the uninformed, and it carries a stigma with it that portrays it and the people who practice it in an undeserved bad light. I don’t want that bad light shining on your mother and I, so before this conversation goes any further I want your solemn promise that what I tell you will go to your grave with you. Can you promise me that?” he asked, looking her in the eyes.
“Yes, Daddy, I promise,” she said, nodding her head and looking him in the eyes. He knew right away that she was telling the truth, because Penny couldn’t look anyone in the eyes whenever she was lying to them. She’d always look away, and this time she didn’t. She looked him square in the eyes when she replied, so he knew she was telling the truth.
“I believe you,” he said, nodding. He paused and took a deep breath before he continued.
“Yes, I like it. I like it very much, as does your mother. And I’m always very careful to make sure I don’t hurt your mom. Before we started practicing it I did a lot of research on it, learning all about the different types and forms of bondage, about where you could apply the straps and where you couldn’t, how to ensure I didn’t restrict blood flow to anything vital, things like that. We also have a ‘safe word’ that we use if things get too uncomfortable for your mom,” he explained.
“What’s a ‘safe word,’ Daddy?” she asked.
“It’s a word that means to stop what I’m doing immediately if your mom says it even once,” he replied.
“Wow, that’s smart!” Penny said, impressed.
“I wish I could take credit for it, but I can’t. That’s part of what I learned when I studied it,” he said. “But I’ve been very careful, and so far you mom hasn’t had to use the safe word at all,” he said, a little bit of pride showing through.
“What’s your safe word?” she asked, more curious now than ever.
“Tabasco,” Arlen replied.
“Cute,” Penny said, smiling. “I suppose now that I know your safe word you’re going to have to use the straps and cuffs on me, huh, Daddy?” she said, half kidding and half serious.
“I don’t think you could handle it, sweetheart,” he said, giving her a little bit of a smile.
“And why not?” she said, sitting up on the edge of the couch and putting her hands on her knees as she put her legs together.
“I just don’t think you could, that’s all,” Arlen replied, even as the mental images of the lithe young body of his little girl bound up tightly in the straps crossed his mind, making his cock stir ever so slightly.
“Is that a challenge, Daddy?” she said, standing up and putting her fists on her hips, her feet spread apart as she looked down at him.
“No, sweetheart, it’s not,” he replied, looking up at her.
“What if I wanted you to do it to me?” she asked, taking the plunge. After all, the worst that could happen was that he’d refuse, right?
“Then I’d say you were biting off more than you could chew,” he replied, unable to get the images of Penny bound up tight and lying on his bed out of his mind.
“And I’d say you don’t know me very well,” she countered. “I’m a lot tougher than I look, you know,” she said, her heart pounding in her chest.
“It’s not just about being tough enough to handle it, sweetheart. There’s much more to it than I think you realize. Bondage is a prelude to...” he was going to say ‘sex,’ but Penny cut him off.
“I want you to do it to me, Daddy,” she said insistently. “I want you to use those straps on me just like you do to Mommy!” she said.
“Sweetheart, you really don’t know what your asking or what you’re about to get into,” he said, trying to warn her.
“There’s only one way to find out, isn’t there?” she said defiantly. Arlen looked up at her for a long moment, trying to decide what he was going to do. A part of him knew that the last person on the planet he should do this with was his daughter, but another part of him – a bigger part – was excited at the idea of putting the straps around her young body and then binding Penny up tight. Then he spoke, just as Penny was about to speak again.
“What’s the safe word?” he asked, his voice soft but stern.
“Tabasco,” she replied. He looked up at her for another moment, then got up out of his chair.
“Okay, let’s go,” he said, walking out of the room. Penny followed him, grinning from ear to ear, her heart pounding in her chest as she followed her father out of the living room, up the stairs, and then down the hallway to his bedroom. Once inside the room he went into his closet and got out the black nylon bag, putting it on the bed.
“What do I need to do, Daddy?” she said excitedly, a big smile on her face.
“Stand right there, and turn around to face the bed,” he said as he pulled three of the rolled-up straps out of the bag.
“Like this?” she said, doing as he said.
“That’s fine,” he replied, unrolling the straps and laying them out on the bed. Then he got two of the bigger straps out and did the same, with Penny watching the entire time. She could already feel her nipples getting hard inside her bra just by looking at the straps. Arlen picked up one of the smaller straps and moved over to stand behind her.
“Put your arms behind your back and grab your forearms,” he said. Penny did as he said, and as soon as she did her father slid one of the straps between her back and her arms, looping it around both of her arms just behind her right wrist, then pulled it tight – very tight.
“Oh!” she gasped as her father pulled the strap tight. She could hear the buckle clinking as he fastened the strap closed, securing the end. He did the same thing to her other arm, binding her arms together and pulling that strap tight as well. Then he slid a third strap between her arms and her back, right in the middle between the two straps already in place, pulling that one tight as well.
“Ungh!” Penny gasped as he pulled the strap tight.
“This is a variation of a Japanese style of bondage called ’Koutou ushiro te shibari,’ “ Arlen explained as he finished with the third buckle, “although the Japanese use natural hemp rope instead of leather straps. I was never any good with knots and it all looked a bit too complicated for me, so I chose to go with leather straps instead,” he said. “Wiggle your fingers for me,” he said, looking down at her hands; she did as she was told, wiggling her fingers with ease.
“No tingling? Your fingers aren’t getting cold?” he asked.
“Nope,” she replied, turning her head and looking over her shoulder. “Is that it?” she asked.
“Not by a long shot,” her father replied, chuckling. “I’m just getting started!”
“Oh,” she said, her voice soft.
‘What did I get myself into?’ she thought to herself as her father picked up one of the longer straps from the bed. She watched with her heart pounding in her chest as he brought the strap down in front of her, passing it in front of her face and then looping it around her body just above her elbows. He cinched this strap tightly around her body, pinning her arms tightly to her sides and restricting her breathing just enough to be a little uncomfortable but not so much as to prevent her from breathing. She gasped loudly as he cinched it tight.
“Oh!” she exclaimed, her eyes wide as her father fastened the strap in place. “Oh my God, that’s tight!” she said breathlessly.
“It’s supposed to be; that’s what bondage is all about,” he explained as he finished securing the strap. “The tightness of the bindings and the feeling of helplessness gets the endorphins flowing which increases the...” he stopped, realizing what he was about to say and stopping before he did.
“Which increases what, Daddy?” she asked, a little breathlessly due to the tightness of the strap around her body.
“Nothing, it’s not important,” he said, reaching for another of the longer straps. He quickly looped this strap around her chest just above her breasts, passing it over her upper arms just below her shoulders.
“UNGH!” she grunted as her father drew the strap tight, her shoulders being compressed inward from the pressure, the buckle clinking as he secured it closed.
“Wow, that’s tight!” she gasped, her eyes a little wide.
“Are you okay, sweetheart?” Arlen asked, pausing in what he was doing.
“Yes, Daddy, I’m fine,” she gasped, still getting used to the tightness of the straps around her body. “I’m just getting used to it, that’s all,” she said, giving him a smile. “So what does all this increase, Daddy? You never said,” she asked, much to his dismay. Arlen paused for a moment before he replied, then decided that she might as well know.
“The flow of endorphins created during the bondage ritual increases the arousal of both parties and makes the sexual experience much more intense and satisfying,” he said, nearly quoting what he’d read about bondage word for word, realizing that he was getting an erection from binding his daughter up.
“Oh,” Penny said, her voice soft, her eyes going wide. At that moment she realized that her nipples were hard as rocks, and that her pussy was getting wet inside her gym shorts.
‘And it’s working, too!’ she thought to herself, then she had a thought that made her eyes go wide and her mouth fall open.
‘Is it working on Daddy, too? Is he getting a boner ... for me?’ she thought to herself, unaware of just how right she was. Then she gasped as her father looped a wide leather collar around her neck, pulling it snug and fastening it in place.
“Not too tight, it is?” he asked; Penny just shook her head in response, too surprised to speak. “Good. This one isn’t meant to be as tight as the others because it’s for something else entirely,” he said.
“What ... what’s it for, Daddy?” Penny asked, a little hesitantly.
“You’ll see,” he replied. Then he pulled the straps around her body a little tighter, starting with the one around her chest.
“OOF!” she grunted as he pulled the straps tight, restricting her breathing a little more, her arms bulging slightly at the edges of the straps.
“Too tight?” he asked, himself a little breathless. His cock was rock-hard and throbbing by now, and he realized that he wanted to fuck his daughter in the worst way. He only wondered if that was what she wanted as well, and if she’d wanted that all along and this was just her way of getting him to do it. In any event, if that was the case she was closer to getting what she wanted than she realized – much, much closer.
“No ... no, I’m good,” she gasped, feeling her pussy getting wetter by the second.
“Turn around,” Arlen said, and Penny did as he asked. As he looked at his daughter bound up tightly in the straps he felt his cock throbbing in his pants, and he could feel his precum already flowing. He looked at her chest and saw that her nipples were hard, poking out against her shirt that was drawn tight around her chest by the straps.
Penny saw the look in her father’s eyes as he looked her up and down, and it was at this moment that she realized she was completely immobilized and was totally helpless, at the mercy of her father who could now do whatever he wanted to her with her being powerless to stop him.
And instead of being afraid she was sexually excited to a level she’d never experienced before. Her nipples were so hard they hurt, and her pussy was absolutely soaked with her juices. The scent of her extreme arousal filled the room, the front of her gym shorts showing the first dark patch of wetness as her juices seeped out of her pussy. She looked down and saw the big lump in her father’s pants, gasping slightly.
‘Oh my God, he’s hard!’ she thought to herself, forcing herself to take her eyes off of the lump in his pants and look at his face instead.
“What ... what happens next, Daddy?” she asked timidly, her voice soft and her eyes wide as she looked up at him.
“This is usually where the subject – the one being bound, which in this case is you – is made to perform fellatio on the one doing the binding,” her father said, his breathing a little faster now than it was before she turned around.
“Fellatio?” she asked, her eyebrows going up as she spoke. “You mean a ... a blow ... a blowjob, right?” she said, stammering with both excitement and fear. The straps were working much better than she could have ever thought they would, and she now wanted to give her father a blowjob more than anything else in the world.
“Right,” Arlen replied, looking her in the eyes. He could see both fear and excitement in her eyes, both of which were to be expected of a newcomer to the bondage ritual.
“But ... but how?” she asked, genuinely not knowing. “I can’t move my arms or use my hands, so how is that supposed to happen?” she asked.
“The man takes care of ... revealing himself ... since the subject can’t do it on her own,” he said, pausing for just a moment before continuing. “After the woman kneels in front of him first, that is,” he said.
“Oh,” Penny said softly, still looking up at him. There was silence for a few moments, and then Penny slowly dropped to her knees in front of him, her face mere inches away from the huge lump of his hard cock inside his pants. She stared at it for a moment, then looked up at him with wide eyes.
“I’m ready, Daddy,” she said, her voice a whisper.
Arlen looked down at her for a few moments, his mind a jumbled confusion of thoughts, desires, needs, and common sense mixing all together. He knew what he wanted to do, what he wanted her to do, and he knew that it was wrong – but at that moment in time, he didn’t care. His sexual desires were taking over, and he knew that he was powerless to stop himself. He just wanted to make sure she knew what she was getting into and that she was ready.
“Penny, are you sure? Are you absolutely sure? Because if we do this it will change things between us forever, and we can never go back,” he said.
“Yes, Daddy, I’m sure,” she said without hesitation, nodding as she spoke, never taking her eyes from his. “I want this, I really do,” she said, looking down at the lump in his pants as she spoke, then looking back up at him, her eyes pleading with him to give her what she wanted.
