Chapter 3: At the Library
The next day, Donny and Sammi entered the well lit university library. He took a moment to look around, taking in the scene. The towering shelves of books, the hushed students going through their research, and the light from the windows created a soothing atmosphere that calmed his nerves.
They found an empty table near a secluded corner of the library and set up their laptops and textbooks. Samantha opened her math book and began typing notes, while Donny struggled to pay attention to his computer science homework. He'd gotten a pic of his girlfriend before they headed out, and he was eager to see what the app could do.
Before he did, though, Donny wanted to test it on the old librarian at the front desk. He quietly snapped a picture of the lady at the front desk, then a freshman girl, probably 19. He set Swap-a-Trait to change their ages, made sure they were both oblivious to the change, and clicked to swap.
Donny's breath hitched as he saw the librarian, a stern-faced woman in her fifties just moments ago, transform before his eyes. Her hair became a wild mane of curls, her skin smoothed out and glowed with youth, and her clothing changed to a casual hoodie and jeans.
"Donny, are you even listening to me?" Samantha asked, bringing him back to reality.
"Sorry, what did you say?" Donny asked, hastily minimizing the app on his phone.
"I said I need your help with this problem set. You're always so distracted lately," Samantha huffed, but she didn't seem too bothered by it.
Donny nodded and turned his attention to the problem set, but he couldn't shake off the feeling of glee that had come from watching the change.
He glanced over at Samantha, who was now completely focused on her math homework. Her blonde hair cascaded down her shoulders in soft waves, and her cat-like green eyes were narrowed in concentration as she wrote on her notebook.
It was time to see what other changes he could make. He saw a short Asian girl come in, and immediately had an idea. The girl was maybe 4'11", and he was curious what Sammi would be like if she were short instead of the statuesque stunner. Taking a quick shot of the short girl, and loading his pic of Sammi, Donny set his app to swap their heights, checked that neither would be aware anything had changed, and pressed the swap button.
Watching the short girl, he saw her legs suddenly grow, her skirt bunching up as her body stretched upwards. As her legs lengthened, her torso narrowed, making her look taller but also thinner. The transformation of her face was subtle, but noticeable - she lost the youthful plumpness in her cheeks and gained a stronger jawline that made her look more mature.
Sammi, on the other hand, began to shrink downwards.
Her tall stature contracted, every inch seeming to disappear before Donny's very eyes. Her blonde hair cascaded downwards, now framing a face that was much more petite and cute. He couldn't help but let out a low whistle as he saw his new Sammi - adorable, short but still the sexy young woman she had been before.
As reality remolded itself, he saw the outfits of Sammi and the now tall and leggy Asian woman had changed too.
The Asian woman now wore Sammi's tight, ripped blue jeans and crop top with the white lace bra peeking through. She still sported the same pair of dirty sneakers she had walk in with, but they looked more fitting now considering her height difference with everyone else around them.
She wore a pair of black leggings that accentuated her now more petite frame, and a baggy shirt that had a print of binary code on it. The neckline was cut low enough to hint at cleavage though she didn't seem to have much now, but the ensemble kept the geeky charm that turned Donny on.
As Sammi leaned over her books, she still had pinned up her hair in a messy bun, leaving a few loose strands to frame her face. Her thick glasses perched on the bridge of her nose, standing out even more with Sammi's new tiny stature.
Donny bit his lip, trying not to laugh out loud at the sheer absurdity of the situation.
Sammi's new small body bounced with curiosity as she looked around to take in the library from the new perspective of her short height. Noticing this, Donny felt his cock stirring in his pants, already imagining all the kinks and games they could explore as this new Sammi, with her new petite body. It wasn't quite what Donny wanted though...
Then he saw the perfect target. Browsing the magazine section was a black girl with a perfect ghetto booty. She was tall, with a perfect bubble butt. Donny's fingers itched to use his Swap-a-Trait app to give Sammi a similar posterior.
He quickly snapped a picture of the Black girl and loaded it onto his phone. Then, he pulled up a picture of Sammi and set the app to swap their butts. He checked the "oblivious" box, ensuring that neither of them would be aware of the change.
As soon as he hit the "swap" button, Donny felt a surge of excitement run through him.
He watched the black girl's body shift and change, her voluptuous curves flattening out until she had a completely flat ass. At the same time, Sammi's body began to transform. The lower half of her petite frame grew rounder, and her small butt suddenly filled out into a perfect, jiggly peach.
Donny couldn't believe what he was seeing. He felt his cock stiffen in his pants as he stared at Sammi's new figure. She looked back at him, confused by his reaction, but Donny couldn't speak. He was too excited by her new figure, and was trying to figure out a way Sammi could sneakily show off her new delicious butt to him.
She tilted her head, giving him a questioning look.
"My eyes are up here, Donny," she said, jokingly crossing her arms over her chest.
Donny snapped out of his stare and realized that he had been caught gaping at her figure. He gave an embarrassed chuckle and looked away.
"I just can't believe how amazing you look," he said, still trying to wrap his head around the sudden change. "Your ass... it's perfect."
Giggling, Sammi stood up from her chair and spun around for him. Giving herself a light spanking, causing her cheeks to jiggle in the most delightful of ways.
Donny was practically drooling at the sight before him. He watched as she gyrated her hips, giving him a little show while she acted like she didn't realize he was enjoying it so much.
"You like it, Donny?" Sammi asked over her shoulder, still twerking with barely contained enthusiasm. "Is this what you wanted to see? Is this what got you so horny for me to begin with?"
Donny couldn't believe his luck.
Here he was, staring at his girlfriend's perfect, voluptuous butt, and she had no idea that he was the one who had given it to her. It was as if the universe had conspired to grant him his deepest desires, and Donny couldn't help but feel a little guilty about it.
But only a little.
Sammi sat back down in her chair, her cheeks flushed with excitement. "So," she said, wiggling her eyebrows at Donny. "Do I pass your little test?"
Donny grinned.
"You passed with flying colors, Sammi."
Sammi smiled back, a playful glint in her eye. "Good. I aim to please."
They went back to their work, but Donny couldn't focus. His mind was still reeling from the transformation he had just witnessed. He couldn't believe how easy it had been to change Sammi's appearance with the Swap-a-Trait app. And the best part was, from her mind, it had always been this way.
Donny couldn't help but feel like a god, creating and shaping Sammi into the perfect girl for him. It was intoxicating.
He continued to browse the library, his eyes wandering to a girl sitting a few tables over. She had an amazing pair of breasts, full and perky with perfect pink nipples that peeked through her thin tank top. Donny felt his pulse quicken as he thought about giving Sammi the same assets.
Without hesitation, he snapped a picture of the girl and loaded it into Swap-a-Trait. He adjusted the settings to swap her chest with Sammi's, then hit the "Go" button.
Instantly, Sammi's body began to change. Her flat chest started to fill out, growing fuller and rounder until they were the same size as the girl's over at the other table.
Sammi's oversized geeky shirt began to stretch as her chest expanded, until a bit of her trim little belly could be seen.
Sammi smirked as Donny stared at her new and impressive cleavage. She looked down at herself to admire it as well, her hands instinctively reaching up to cup her impressive assets. She gave a quick sigh of enjoyment, then looked around to make sure nobody saw her touch herself. Nobody seemed to be paying her any mind, and Sammi turned to Donny with a sly grin. "I don't know what's changed to get you so worked up," she said, her voice dripping with amusement, "But I hope you're having fun."
Donny's eyes widened as he took in Sammi's new appearance. He had always thought she was beautiful, but now she was absolutely stunning. Her body was now the perfect hourglass shape, with full breasts that he couldn't wait to get his hands on.
"Holy shit, Sammi," he stammered, trying to keep his cool. "It's just you look so incredible."
She giggled, clearly enjoying his reaction. "Thanks, Donny. I have to admit, I'm feeling pretty good about myself right now." Sammi's eyes sparkled with amusement as she glanced down at her chest.
Donny couldn't help but chuckle at her enthusiasm. He looked over at the woman in the tank top whose chest had been swapped with Sammi's. She didn't seem to notice the change, and was still engrossed in her book.
Her new flat chest was visible under her tank top, a stark contrast to the ample curves she had just a few moments ago. Donny couldn't help but feel a twinge of arousal at the sight of her now slim frame and practically non-existent breasts, knowing they'd all gone to his now busty short-stack of a girlfriend.
As they continued to study, Donny found himself stealing glances at Sammi's new chest, admiring the way her nipples poked through the thin fabric of her shirt. He couldn't wait to touch them, to feel their weight in his hands.
Sammi and Donny continued to chat and laugh as they studied, their flirtation escalating with each passing moment. Though from Sammi's perspective she'd always had an impressive chest and ass on her short little frame, she seemed delighted by the attention.
They finished up their work and started heading to the cafeteria for dinner. As they both stood, Sammi was noticeably shorter than Donny, and he noticed she was wearing a pair of platform heels to try and seem taller.
Donny couldn't help but chuckle as he watched her striding along in her heels, as he slowed his pace so she wouldn't have work so hard to match his strides. "I may be little, but I can keep up," Sammi announced and gave Donny a playful smirk as she slid one of her hands into her boyfriend's back pocket, leaning against him. Donny glanced down, feeling a thrill of desire as his view looked right down her shirt. They continued with Donny enjoying the movements of Sammi's new curves.
"Oh, Donny," she said, as she adjusted her thick pair of glasses. "Hey! Instead of the cafeteria, you want to order a pizza and fool around a little?"
Before Donny could answer, he saw a goth girl walk past. She had short spiky black hair, a pale face with dark eyeliner, and was dressed in all black with heavy chains and buckles. Donny couldn't help but wonder what Sammi would look like with that style.
Sammi caught Donny staring at the goth girl, and gave a dismissive snort. "What are you looking at?" she asked.
Donny hesitated for a moment, then decided to tell her the truth. "I was just thinking, you'd look really hot as a goth."
Sammi gave a load guffaw at the statement. "Really?!" She asked incredulously, "Me as a goth? Those girls all have issues and besides, that'd be way too much work!"
But Donny wasn't joking. He had always found goth girls to be incredibly attractive, and now that he had the power to change Sammi's look with just a few taps on his phone, he couldn't resist the temptation.
Without saying a word, he opened his Swap-a-Trait app and took a picture of the goth girl. He then quickly snapped a picture of Sammi, and within seconds, the transformation was complete.
Sammi looked almost unrecognizable from the blonde bombshell that she was just a short time ago. She now was clothed in a smooth corset and black mini combo that revealed her ample cleavage, a pair of thigh-high lace stockings, and shiny patent leather boots with stiletto heels.
Gone were Sammi's blonde locks, replaced with a jet-black bob framing her heart-shaped face. Her fair complexion was now a pale, almost translucent hue, setting off her piercing green eyes, which now had a thick line of black eyeliner around them. Her thick glasses were still there, but now the frames were catseye shaped, giving her the look of a kinky librarian. Her lips, painted a deep shade of purple, curved into a smirk as she looked at the girl whose style Sammi traded with.
The girl was now dressed in a pink sweater with cartoon dinosaur on it, faded jeans, and some uggs boots, matching Sammi's old geek chic style. She glance at Sammi's new gothic outfit and walked away with her own smirk etched on her face, like she was silently judging the shorter woman.
"Did you see that, beloved? Getting judged by some basic normal!" Sammi asked with a scoff, oblivious to her own similar behavior.
Sammi glanced down at her own outfit to confirm she was dressed exactly how she intended.
"Mmmm, dearest, I look fucking delectable!" Sammi stated with satisfaction, adjusting her bosom as she admired her reflection in a window they passed by. She moved closer to Danni, with a smoldering grin, "Aren't you glad you have a dark and mysterious soul as your one and only?" Sammi asked Donny, though she already knew the answer.
Donny gave a smile back to her. He was a little surprised by how her new style changed Sammi's behavior too, but it just made him all the more eager to get her back to their dorm.
As they saw their dorm, Donny hurried ahead to get the door for his girlfriend.
Sammi curtsied past her boyfriend with a grin as she entered their dorm, pulling out her phone to order the pizza. They waited for the elevator in their dorm's lobby, a few folks waving at them as they walked past. Donny was still amazed how nobody reacted to Sammi living in the guys dorm. Somehow, the app had made things normal for everyone else.
The elevator opened, and Donny and Sammi hurried on. Another student was about to grab it, but saw the couple and thought better, though Donny thought he heard the guy mutter "lucky prick" as the doors closed with just him and Sammi in the elevator.
Sammi gave her boyfriend a look and immediately pressed the "Stop Elevator" button between the floors, giving Donny a devilish grin as she playfully stuck out her tongue, showing off a black stud in it.
His heart raced as she approached him, pressing her newly augmented cleavage against him. "Oh no, looks like we're trapped," she said, grinning mischievously.
Before Donny could respond, she wrapped her arms around his neck and pulled him down for a deep kiss. Donny was taken aback at first but quickly succumbed to the passion, his hands wandering down her new gothic outfit, feeling the curve of her waist and the firmness of her backside.
When they finally broke apart for air, Sammi looked up at Donny with a hungry gaze. "I want you, Donny. Right here, right now," she said, her voice husky with desire.
"I want to feel you, all of you, on me, in me."
Donny's breath hitched as Sammi undid his belt buckle, her slender fingers deftly unbuttoning his jeans. Her movements were deliberate and intentional, her gaze never leaving his as she lowered herself to her knees. With a wicked smile, she pulled down his jeans and underwear in one swift motion, revealing his hardening cock.
She wasted no time taking him into her mouth, her hot lips enveloping him as she sucked and stroked him.
Donny let out a low moan as he felt her tongue swirl around his shaft, teasing every inch of him. He reached down to tangle his hands in her short black hair, pulling it back to watch her as she pleasure him.
Sammi looked up at him, her eyes heavy-lidded and lust-filled. She knew exactly what she was doing to him, and it was written all over her face. Donny had never seen her so confident, so seductive, and it only made him want her more.
He could feel himself nearing his climax, his breathing quickened as his grip tightened in her hair.
But before he could cum, Sammi pulled back, a wicked grin on her face.
"Not yet," she whispered, standing up to face him. She reached behind her, undoing her corset and letting it fall to the floor. Her full tits bounced free, a pair of pierced nipples hard and pointing straight at Donny.
He moaned at the sight of her, so fucking hot and confident. She sauntered up to him, pressing her body against him once more, rubbing her tits against his chest.
She reached down and started to stroke his cock again, causing him to moan and shudder.
"Don't worry, love," she purred. "I'll make you cum harder than you could ever have dreamed of."
And with that, she pushed him against the wall of the elevator and climbed him like a tree.
Her legs wrapped around his waist as he lifted her up, her hot pussy grinding against his cock.
He could feel her wetness seeping through his boxers and onto his skin, making him even harder than he already was.
Without a moment's hesitation, Donny slid himself into her tight, wet pussy.
Sammi let out a loud moan as he filled her up, her nails digging into his shoulders as he started to thrust in and out of her.
He could feel every inch of her pussy gripping him, milking him for all he was worth.
He couldn't believe this was happening, that he was in an elevator with his goth girlfriend, fucking her like this. It was so dirty, so wrong, but it felt so fucking right.
Sammi's head fell back as she moaned, her short black hair shaking wildly. Her full tits bounced with each thrust of Donny's hips, her nipples peaked from the attention.
Donny reached up to grab them, tugging on the piercings as he fucked her harder. "Fuck, Sammi," he groaned. "You feel so goddamn good."
Sammi let out a laugh and leaned in to whisper in Donny's ear, her voice husky and raw with lust. "I know, beloved. Your soul is the only one that can sate my passion."
Her odd sex talk aside, everything about Sammi right now sent a shiver down Donny's spine. He thrust into her even harder, making the elevator shake with the force of their lovemaking.
Sammi wrapped her legs tighter around him, pulling him deeper inside her.
Her black nails dug into his shoulders as she matched him thrust for thrust, their bodies slapping together in the confined space of the elevator. It was a rough and dirty, and exactly what Donny needed.
Their moans filled the elevator, echoing off the walls as they lost themselves in their pleasure. Donny could feel Sammi's walls tightening around him, telling him that she was close. He gritted his teeth, determined to make her cum hard before he did.
"Fuck, Donny!" Sammi cried out, her pussy clenching around him like a vice.
She threw her head back and let out a long, low moan as she came hard on his cock, her juices flowing down his shaft and coating his balls.
Donny couldn't hold back any longer. With a final, powerful thrust, he came hard inside of her, filling her up with his hot, sticky cum. He groaned as he emptied himself inside of her, his legs shaking from the force of his orgasm.
They stayed like that for a moment, their bodies still connected as they caught their breath.
Donny's cock was still buried deep inside of Sammi, both of them still trembling from the force of their orgasms.
Finally, Donny pulled out of her, and they both stumbled back to the other side of the elevator, panting and trying to catch their breath.
Sammi looked up at him, a warm smile on her pale face. "It seems unfair that our dormmates can't use this elevator. Shall we continue in our room?" she asked, her voice dripping with eager desire.
Donny couldn't help but laugh at her boldness. They threw their clothes back on so they were presentable, and started the elevator back up, Sammi doing her best to keep Donny's seed from spilling down her leg.
When they reached their floor, they practically ran to their dorm room to tear each other's clothes off again. Donny's hands were already on Sammi's ass, groping and squeezing it as she giggled and tried to playfully get away from him.
Once they got inside, Donny quickly shut and locked the door behind them, then came up behind Sammi and pulled her close to him again. He ran his hands over her curves, enjoying the feel of her shapely hips and full breasts.
She flipped herself around to reveal her ass to him, and Donny couldn't resist the urge to spank it, running his hand up and down her plump, round cheeks. Sammi let out a squeal of delight as he cupped each cheek in his hands, kneading them with tenderness.
"Oh my god, Donny," she moaned as he slipped a finger between her plump lips.
Donny Pressed against her body, grinding his erection against her ass.
Sammi reached back and guided him to her wet entrance, impaling herself on him without hesitation.
He moaned as her tight heat enveloped him. Her walls were slick and hot, writhing around his dick in a wave of pleasure that pulsed through his entire being.
Donny grabbed her hips hard, pumping into her with pent-up passion that built up over hours of craving.
Sammi arched her back, emitting a low moan of satisfaction.
"Fuck, Donny, that feels so good."
Donny knew exactly what she meant. He could feel her muscles clench and unclench around his shaft, and it was the most amazing thing he had ever felt. The pleasure was beyond anything he had ever experienced, and he couldn't help but let out a primal growl.
He wrapped his arm around her waist, pulling her tight against him, as he began to thrust harder into her pussy. Sammi met his every thrust with one of her own, grinding back against him.
He could feel her body beginning to quiver, her moans growing louder and more desperate. Donny knew she was close, and he began pumping into her harder, faster.
"Donny, yes!" she screamed, her body shuddering as she came hard on his cock. Her pussy clamped down on him like a vice, milking him for every last drop as he filled her with his cum.
"Oh fuck, Sammi!" he shouted, grabbing onto her hips as he plunged into her one final time before collapsing onto her back.
Their bodies lay there, tangled and sweaty, as they caught their breath and reveled in the afterglow.
Sammi looked up at Donny and smiled, a satisfied grin stretching across her darkened face. "Fuck, that was amazing," she said, running her fingers through the sweat that had collected on Donny's forehead.
Donny smiled back, a look of pure pleasure blanketing his face. "I've never felt anything like that before," he admitted, his voice still hoarse from his orgasm.
Sammi giggled, lying back down on the bed next to him. "You sure are a late bloomer when it comes to the pleasures of the flesh."
Donny chuckled, rolling over to face her. "Well, I never had anyone who made me feel as comfortable with myself as you do."
He leaned in and kissed her deeply, his hand wandering down to caress her breast.
Sammi let out a satisfied sigh, running her fingers through Donny's hair.
