Chapter Text
After two minutes, Gwen opened the changing room's red curtain again. This time, she was wearing a fancy sleeveless black dress. It was classy, but clearly too flimsy for a dinner party. Her cleavage, in particular, was very low-cut; it almost went down to her navel. As for its hem, it was so high that it barely covered her rear.
It's like the college girl purposely chose a dress that was two sizes smaller than her own. Which might well be the case, because it was extremely body-hugging...
"What do you think of my cocktail dress, Daddy? Am I stylish?" Gwen asked, maliciously.

It was racy, shameless, provocative, inappropriate... But Mr. Williams couldn't deny he was blown away by how stunning his step-daughter looked in this. He noticed that she once again refrained from putting on a bra — it was starting to become a bad habit of hers, it seemed. With how slim the strings holding her dress together on her shoulders were, any false movement might unveil one of her nipples. All in all, in was very risqué...
"Maybe it's... too posh, y'know?" Patrick coughed, uneasily.
"Oh, I perfectly get what you mean, Daddy. You wouldn't want your dear step-daughter to look 'posh' now, would you?" Gwen chuckled. "Anyway, I'm a little nervous, I've never worn anything like this before."
"I can understand why," Mr. Williams cringed. "Don't get me wrong, this looks great on you. But perhaps a little... a little too great, I'd say? I mean, don't you think it's a lil'... too revealing?"
"Again with my outfit being too revealing? You're being super old-fashioned, Daddy!" she pouted. "A girl shouldn't be ashamed of her own body. Don't you think I should be proud of who I am, of what I look like?"
"Yes, obviously, and if people judge or stare at you, they're the ones in the wrong!" the older man replied. "But there still are some... social norms to respect. You're a smart girl, I know you know what I'm talking about, Gwendolyn."
"Honestly, I do not. I always found it too bad that people have to live their lives according to some made up code of conduct," the pretty blonde argued. "All the moral norms we believe in are merely social constructs, we learn all about that in college. It's also why doing things that are considered taboo and off-limits can feel so liberating and... thrilling. ❤︎"
To drive her point home, Gwen caressed her rose cheek, slightly bit her lower lip and gave the older man the dirtiest "Fuck Me Eyes" to entice him. Every time she gave guys that look during college parties, they never failed to melt. After that, she had them wrapped around her finger and doing whatever she wanted them to do like good little boys. It was like black magic, a secret spell no one was immune to...
"Don't tell me you've never wanted to take a bite from a forbidden fruit yourself, Daddy?" the 20-year-old girl mused. "I'd have a hard time believing it... "

That was it, that was the thing that would finally make the old man crack! There was no way he'd resist her deadly glamour! At least, that what Gwen believed because, to her disappointment, Mr. Williams once again withstood her attack. He clenched his fists on the armrests of the sofa and turned his gaze away from her.
"I'm not sure what you mean by that, and I don't care to know..." he replied, coldly. "As for that dress, it may be elegant, but let's be honest, it doesn't look very comfy to wear."
Shit, the old jerk really wasn't caving in, huh? His concerned comment also weirdly landed. He was right, this outfit wasn't pleasant to wear at all. Gwen's waist was compressed by the sleek fabric and she'd definitely catch a cold if she ever wore something this flimsy outside.
But that's not something the college girl would ever admit. Comfiness wasn't the point here, and she was ready to endure any discomfort as long as it helped her to break her step-dad's will. If her signature stare wasn't enough to achieve that, she'd simply shift to a new strategy.
"I'm sad you don't like this one, Daddy," the cute blonde girl sighed. "It's a nice dress, I bet it'd look good in pictures. Actually, could you do a photo of me with it?"
"A photo? What for?" Patrick asked, raising an eyebrow.
"For my Instagram page, silly! All girls in Uni have one. Please, take your phone out and snap a pic. I'd really like to know how I look."
The middle-aged man hesitated for a second. He was starting to understand the game his troublesome step-daughter was playing, but there was no harm in granting her request. He retrieved his phone from his pocket with a resigned groan.
"I'm not sure it's your step-dad's place to help you create online content," Patrick mumbled, while launching the photo app on his phone.
"Depends on the content. There's a whole sub-genre online of step-fathers doing a lot of content with their step-daughters, if you know where to look!" Gwen joked.
"H-hold on a sec, are you referring to...?"
Mr. Williams' eyes widened at the implication of her words, but the blonde girl swiftly turned around instead of answering.
"So, what do you think? Business in the front, party in the back!" she said, playfully.
The front was arguably not very businesslike, and the back was even worse. Gwen's back was completely uncovered; the fabric only started around her hips and it barely concealed her round buttcheeks. And it was tight. Very tight! Patrick could fully see the shape of her ass under the black satin.
"See, it's very comfortable..." the naughty college girl teased. "Only thing I'm worried about is the fact it might be... too short. That's why I need a picture."
Gwen's smile grew wider as she caught her mother's husband's eyes lingering on her backside. This time, she definitely had the bastard hooked! She began to sway her hips in a tantalizing manner, and Mr. Williams was unable to tear his gaze away from her. It's like he was hypnotized by her pendulum movement. Every shake of her hips was luring him with the curves of her hourglass figure.
The middle-aged man snapped of his funk when he realized that he was blatantly checking his wife's daughter's butt and he diverted his attention back to his phone like nothing happened. However, at the exact moment he took the picture, Gwen pulled up her black dress and undisclosed her lush posterior. Mr. Williams nearly froze when he saw the picture on his phone.
"Err... I can see your ass, Gwendolyn..." he said, anxiously.
"I know, I love how my butt looks in this dress! Don't you think my ass looks cute like this, Daddy?" the blonde girl asked, looking back at him without lowering her gown.

Patrick felt his throat turn dry. Shit, he couldn't believe he currently had a picture of his step-daughter flashing her ass saved up on his phone! He put it away as if it had turned into a venomous snake, but the reality in front of him was even worse. The black laced panties that Gwen adorned under her dress were so slim that they were nothing more than a string between her exposed asscheeks. It was even more daring than those weird pajamas she wore at night!
"Lower your skirt, please. And I'm certainly not answering your rather... *cough*... dubious question, Gwendolyn," Patrick replied, trying to calm his heart rate. "Also, you mentioned it was for your Instagram account, but I really think you should refrain from publishing this type of picture online."
"Why? Don't tell me you think it makes me look slutty?" the 20-year-old girl teased.
"Well, I don't like putting things that way, but... kinda, yes. I know there's this whole sub-economy of so-called 'thirst traps' on social media, but you want no part in this, believe me."
"You think I'm posting thirst traps on my Instagram? It hurts, coming from you," Gwen frowned. "But maybe that's the way to go. Sometimes, guys like girls who act a bit slutty. Do you like slutty girls, Daddy?"
She started swaying her hips again, but this time it had the opposite effect. Mr. Williams' face turned red from anger. The way his step-daughter's kept on taunting him was really starting to get on his nerves, he wasn't going to let that brat make a fool of him!
"Enough is enough!" he scolded her. "Lower that dress and get back in that changing room this instant, young lady! I'll send you your stupid picture since you want it so much, but I'm deleting it from my phone. You're a grown up, you can do whatever you want to with it, but I don't want to hear a single word of it! About this, about 'thirst traps', or anything of the sort, is that clear!?"
"Alright, alright... I was just making small talk, you're such a buzzkill!" Gwen muttered, before getting back into the fitting room.
The 20-year-old girl closed the curtain behind her and her phone buzzed in the pocket of her handbag, indicating her step-dad sent her the picture. Crap, she really hoped this sexy dress would fluster him more than that. She needed to rethink her approach here.
After pondering on her next step, she seized another outfit from one of the hangers. Since it was a bit complicated to put on, she started making conversation while changing.
"By the way, what do you think the store clerk thought of us when we walked in?" she said, as she removed her dress and put a white shirt on.
"I don't know. Just a guy and his daughter buying stuff on a Saturday afternoon, I guess?" Patrick shrugged. "What do you care?"
"Do you think he might have thought... y'know, that you and I are, like, an item?" she asked, slyly.

The middle-aged man frowned. For real, was there no end to that girl's weird questions?
"What the hell are you on about?" he asked, almost sounding offended.
"Yeah, perhaps some people think you're my boyfriend when we go out together," Gwen continued, while buttoning up her shirt above her bare breasts. "It's kind of funny to think about it."
"That is preposterous!" Patrick cut her off. "I'm a chubby guy nearing on his fifties, and you're a student girl barely out of high school. Of course, people don't think you and I are dating, it makes no sense! They probably believe we're related."
"Honestly, I wouldn't mind," Gwen purred from behind the curtain. "Guys never try to hit on me when you're by my side, Daddy. They must feel intimidated by a man who's more mature, more poised and manly than they are. I think I like it when people see us here together and think we're a couple..."
Patrick massaged his eyelids, feeling profoundly tired by his step-daughter shenanigans. Alright, that little prankster wanted to play this stupid game? So be it, he'd play it too then, and now was the time for a hard reality check.
"Really? It doesn't bother you that people would think you're dating a guy like me?" he scoffed. "I'm not exactly 'college girl's boyfriend' material, if you hadn't noticed. Girls your age tend to date guys a lot younger than I am. What would your friends and classmates think? Probably that you're a gold digger, or a girl who has severe daddy issues. That would make you the target of all types of gossip. Is that what you want, Gwendolyn? For people to think you're a circus freak?"
"I told you, I wouldn't mind," the 20-year-old girl replied, unmoved. "A lot of people still treat me like I'm a teen or something, but I'm a big girl now, and I want people to understand it! Going around with you makes me appear older and more grown-up than I am, which I really like. It seems it's you who's bothered by the idea. I just got dumped, so this is making me feel very insecure. Would you feel so bad if people thought you were dating me, Daddy? Are you ashamed of me?"
Crap, she really had a knack for twisting words in her favor. Now, Patrick was feeling bad.
"No, that's not it," he said, trying to sound sympathetic. "Anyone would be proud to have a girlfriend like you, Gwendolyn. You're beautiful and smart, having you by my side would make all men envy me."
"Really? You're not just saying that to please me?"
"No, darling. It's just... it simply wouldn't be appropriate. You're way too young for a man my age, and I'm married to your mother."
"Of course, of course, we're just making silly scenarios in our heads here, Daddy. Still, thanks for being honest with me!"
Mr. Williams was relieved the young blonde accepted his answer and didn't try to push things further. However, it still felt a little weird to say he'd feel "proud" to date his step-daughter out loud. That wasn't a sentence he never expected to speak one day...
"So, new outfit, what do you think about this one?" Gwen asked, when coming out of the changing room. "College won't last forever and I'll have to start doing some internships soon, so I need to look like a professional. Do you think that works?"

Mr. Williams was a bit thrown off by her new garb. It was significantly less problematic than the two previous ones: Gwen tied up her short hair into a bun and was wearing a fancy white shirt, as well as a black belt and a black pencil skirt. On paper, it didn't look particularly dubious but, as always, the devil is in the details.
The young blonde left several buttons of her shirt opened, giving a plunging view of her cleavage and revealing — once again — that she had no bra on. Her pencil skirt was also extremely short, and the fishnet stockings and garter belt she wore underneath made her look like a secretary straight out of a porn rather than a young, promising trainee. It was more tasteful than before, but she was still looking... lewd. For lack of a better word, his step-daughter was looking very, very lewd...
"Okay, no, that's... that's really not an appropriate work outfit," Patrick said, shaking his head.
"Really? I genuinely thought I hit the mark with that one."
"I mean... The shirt is alright, but you need to button it up. That pencil skirt also has to go. This isn't the 80s, women don't necessary wear skirts in the workplace anymore. As for those stockings and garter belt... It's not banned or anything, but I'd really advise against wearing them in an office."
"Why?" Gwen smirked. "Don't tell me you'd be inappropriate with me if I was your intern, Daddy?"
"Wh... What kind of question is that? Of course not! I'd never harass a colleague, especially my own step-daughter!"
"Of course, you wouldn't, Daddy. You're not like that. I meant in theory," the 20-year-old girl mused. "I'm just saying, imagine the scene: after a long hard day at work, your cute intern walks into your office dressed like this. You two are all alone, and she gets near your seat to pour you a warm cup of coffee. At that moment, her skirt raises slightly, just enough for you to catch a glimpse of something you definitely shouldn't see. Wouldn't you be... tempted?"
Gwen turned around and arched her back forward. Her pencil microskirt moved up her butt, revealing her black panties and the upper part of her garter belt. Her voluptuous, curvy ass was only an arm's length away from where her step-dad was sitting. It was offered on a silver platter...
"Be honest, Daddy. Wouldn't you want to cop a feel? Not even a little bit?" she whispered sweetly, while looking back at him.

To her surprise, Patrick stood up abruptly from his seat. His face was enraged, she had never seen in him before. His reaction startled the college girl a little. It was the least sexy outfit she tried so far, what was happening to him?
"Alright, let's make one thing clear here: never, ever accept any form of harassment in the workplace, Gwendolyn!" he said, sternly. "If anyone causes you trouble, you run to HR or to your manager. You don't let any of that shit slide, understood?"
"I... Uh... Of course, Daddy... I mean, this was just a quip..." Gwen replied, baffled by his outburst.
"This is no laughing matter!" the older man cut her off. "Sexual harassment has crippled the careers of too many women in my time, and there's still a lot of work to do to bring men and women on equal grounds in the workplace. You're going to start a career of your own soon, and I'll be dead in the cold ground until I let some asshole prevent you from exploring your full potential! You deserve more than this!"
"I... Alright, I... I understand, sir. Th-thanks..."
Gwen quickly retreated back into the changing room, feeling completely disoriented. What the hell was that all about? The reason she teased Mr. Williams was to push him to make a mistake and cause her mom divorce him. Doing that, she thought he'd yield to temptation and reveal the fact he was secretly a pervert like the rest of men, not that he'd act like... well, like an actual, decent dad!
It was the first time someone talked to her like this since her father's passing, come to think of it. This was making her feel weird... She was so thrown off that she even called him "sir", for God knows what reason.
The 20-year-old girl slapped her cheeks and tried to shake off this strange feeling, she couldn't let this affect her plan for today. You know what, fuck this! If Patrick resisted her and tried to act all virtuous and protective, she'd simply double down on her provocation. No more clever plotting, no more cunning stratagem. She was going to go balls to the wall with her final dress!
"Daddy, could I ask for a favor?" Gwen said, while undressing.
"Depends on the favor..." Patrick grunted, suspiciously.
"This is embarrassing. See, the changing room has no hooks left to hang my clothes from, and this thing I'm trying is, like... really small. I can't wear my underwear underneath it, and I don't want to put them on the floor. They might get dirty."
"Yeah, I guess can see the hygiene issue," the older man replied, while stroking his chin.
"Perfect. Since you see the problem, would you be so kind as to keep this for me, Daddy?"
Gwen didn't leave the older man time to understand what she meant. She slightly opened the red curtain and handed him over two pieces of fabric. Patrick took it as a reflex, until he understood what he had in his hand.
Her panties and bra. He currently had his... his step-daughter's underwear in his hand, freshly worn!
"W-What the... I... I wasn't expecting that!" he nearly shouted.
"Thanks, Daddy, you're the best! A real life savior!" Gwen replied, winking at him cheekily.

She closed the curtain back and the middle-aged man just stood there, straight as an arrow, looking at the female lingerie he had between his fingers. It was still warm. The black panties in his palm were still warm from being in contact with her... with his step-daughter's...
Something tensed in his pants.
"Hooooooly shit... Keep it together, Patrick... Just... Fucking keep it together..." he mumbled to himself.
Gwen heard him from inside the changing room and hid a little chuckle. Great, her ploy was working. Now was time for the killing blow!
"Hey, can you come over inside the fitting room?" she asked, very innocently. "This one is a little weird, I'm not sure it's something I should wear outside."
"Then perhaps it means you shouldn't show it to your step-dad either?" Patrick winced.
"Alright, fine. Then I suppose I'll have to fight my self-consciousness and come out... You're a big meanie, Daddy. ❤︎"
Gwen opened the curtain and smiled as she came out into the hallway of the fitting area. Earlier, she gathered a selection of bikinis. Each swimsuit she tried accentuated her curves in all the right places, but, of course, she found the skimpiest one in the whole store. the scanty bikini she was wearing was all pink and glittery, and it only covered her tits and half of her crotch. Parts of the areola of her nipples were even visible.
Wearing so little fabric on her skin basically amounted to walk around naked in the store's changing area. Some people surely already ended up in jail for public exposure for less than that!
"Would you mind taking a long, hard look and telling me what you think of my bikini, Daddy? I'm not sure if it looks good or not," she asked, feigning not to realize how outrageous her swimwear was.

The curves of her beautiful, young body left the older man speechless. She even twirled around to give him a full view.
"Like what you see, huh? I knew this one would catch your eye," she giggled.
Patrick looked around them and felt a cold sweat run down his spine. Thankfully, they were alone, but it would be a very difficult situation to explain if anyone found them. Because no one was going to buy the fact they were simply having a fun daddy-daughter shopping spree if they found him alone in the back of a store with a nearly naked girl less than half his age. This setting was wrong. Wrong on so many levels!
"What the hell is this, Gwendolyn!?" Mr. Williams said, trying to keep his voice low. "I know you're, huh... comfortable showing a lot of skin, but that's... that's just too much!"
"Really? It makes me feel quite sexy, actually. The strings hug my curves perfectly, and it makes my boobs look bigger. Cool, huh?" the cute blonde answered. "It's way more revealing than anything I own, but that's what's fun about it, don't you think? I was planning on going to the pool on campus with it. You think it's too spicy?"
"'Spicy'? This is beyond 'spicy', this is molten frigging lava!" Patrick seethed. "Jesus, Gwendolyn, we're in public! People could walk in at any moment! And this thing is all... all glittery. Are you sure this is even an actual swimsuit? It looks like something straight out of a strip-club!"
"Nonsense, Daddy! Don't tell me you're imagining how I'd look like if I were a stripper!?"
"I... What? No, of course not! That's not what I'm saying."
"You were talking about me having a big career but, in truth, you'd actually like for your step- daughter to become a stripper?" Gwen laughed, pushing her advantage. "♪Naughtyyyy daddyyyy♫! Does it mean you'd come watch me dance on stage? Throw a dollarbill or two at my feet? Maybe even ask for a private lap dance?"
"Okay, stop! I didn't say that! I repeat: as God is my witness, I did not say that!"
"Y'know what, I'll think about it," the cute blonde nodded. "There are some pole dance classes on campus. Apparently, it's really tough, a real fuuuuu~~~ll body workout! I was getting tired of yoga, so thanks for the nice recommendation!"
"Stop that! I didn't recommend anything!" Patrick replied, completely panicked.
"Yes, you did. I was feeling super insecure about my figure ever since my last break-up. But knowing my Daddy thinks I have the right body to become a stripper is a really nice compliment. It's all the approval I needed!"
Gwen stepped closer to him. Dangerously closer. Then, with a slow and calculated movement, she grabbed onto one of her breasts and moved it upward, as if to invite him in.
"Here, do you want to catch a feel as a thank you? Just to be sure I'd look pretty on stage?" the sexy blonde asked, in a low, seductive voice.

Patrick's lips were trembling, beads of sweat were running from his forehead and his jugular was pulsating like a drum on his neck. He was close to breaking. She could feel it, he was so, so close!
But then, the fat older man dropped the underwear he was holding and took his wallet out. He fumbled inside it and handed her his credit card, his hand trembling as if he'd just seen a ghost.
"I... I have to go," he stuttered. "H-here, take my credit card. The code's 1917, just... buy yourself something nice."
Once Gwen took the card, he ran like hell. Not looking back twice, as if the Devil himself was on his tail.
"But... Wait, you're my ride home!" she screamed.
"Just... catch a cab, I'll pay for it. I really have this... this emergency, I'm sorry."
In a matter of seconds, Patrick vanished and Gwen was left alone in her stupid pink bikini in the fitting area. Wow... That's was... not the reaction she was aiming for!
This was undoubtedly a setback. She really thought she hooked him, this time around. The old bastard was playing hard to get, she expected him to break sooner. This game of cat and mouse was starting to really piss her off!
"Alright, you win this round, old man," she conceded. "But you made a mistake, leaving me access to your bank account. Now that I have unlimited resources, I have the means to build an arsenal of slutty clothes and lewd accessories, the likes of which the world has never seen. You better believe it, Daddy, your step-daughter is going to bring home some heavy weaponry!"
