At the airport

"Timmy, darling," Beverly says, her voice dripping with sugared sweetness that's all too familiar. She stands outside the taxi, her eyes scanning the bustling airport. "Could you be a dear and grab all the luggage?" She tilts her head to the side, her blonde hair cascading over her bare shoulder. "My nails are just so freshly done, and I'd hate for them to get ruined."

Tim sighs heavily, his eyes darting around the taxi to make sure no one is watching. "Fine," he mutters, trying to keep his voice low. He grabs the luggage, feeling the weight of it in his arms. It's a stark reminder of the weight of the situation. He slams the taxi door shut, the sound echoing through the parking lot.

"Thank you, darling," Beverly says, her voice still Tracy's but with a smugness that is all her own. She sashays away from the taxi, her hips swaying more exaggeratedly than Tim has ever seen Tracy do. She doesn't bother to look back as she heads towards the airport terminal, leaving Tim to struggle with the luggage.

"Bev, wait up!" Tim calls out, his voice tight with annoyance. He's about to say something else when he remembers their agreement. He takes a deep breath and calls out, "Tracy, wait for me!" His heart skips a beat as he says her name, feeling like a lie on his tongue.

"Tim, darling," Beverly says, turning to face him with a smile that's all Tracy, but the glint in her eyes is pure Beverly. She walks back, her heels clicking on the pavement. "Is everything okay?" She asks, her voice dripping with faux concern.

"Yes, everything's fine," Tim says through gritted teeth, trying to keep his voice calm. "Let's just get to the check-in." He tries to steer the conversation away from the awkwardness of calling her by Tracy's name.

Beverly sashays towards the check-in counter, her stride long and confident in a way that's eerily similar to Tracy's. She's clearly enjoying the extra height and the way her new body moves. The flight attendant, a tall, dark-haired man with piercings and a leather jacket slung over his shoulder, looks up and his eyes widen. He's exactly the type of guy Beverly would've flirted with in her own body, and she knows it. She gives him a coy smile as Tim lugs the luggage over. "Good morning," she says in Tracy's sweet voice, but the words hold a bite. "Could you help us check in?" She leans over the counter, giving him a generous view of her cleavage. Tim's eyes widen in horror as he sees the attendant's gaze linger.

Tim's eyes dart around the airport, hoping no one they know will spot them. The way Beverly is acting is making his skin crawl, but he knows he can't blow their cover. He forces a smile and sets the luggage down with a thud. "Yes, please," he says, his voice tight. He can feel his cheeks burning as the attendant's gaze lingers on 'Tracy's' chest. The dress she's wearing is so thin that he can see the outline of her nipples, and the way she's leaning makes it clear she's not wearing a bra. He tugs at his collar, trying to cool down. "We're going to Hawaii," he adds, trying to keep the conversation on track.

"Oh, Hawaii," the attendant says, his eyes still fixed on Beverly's chest. "How romantic." He licks his lips, and Tim can't help but feel a surge of jealousy. This isn't his Tracy, but the body she's wearing is so close to perfection that it's hard not to feel a twinge of something. Beverly giggles, her new body reacting to the attention in ways she's never felt before. She straightens up, and Tim notices her nipples are now clearly visible through the fabric of the dress, standing at attention like two little soldiers. She doesn't bother to hide it, instead leaning in closer, her breath hot on the attendant's neck. "Could you make sure we get the best seats?" she purrs, her voice a siren's call.

The flight attendant, clearly flustered, nods eagerly, his eyes darting down to the slip of fabric that's barely concealing her areola. "Of course, Miss," he stammers, his fingers flying over the keyboard. Beverly leans in even closer, her breasts brushing against the counter. One hand lingers by her chest, as if it might accidentally slip and reveal even more. She whispers something into the attendant's ear, and his cheeks redden. Tim can't help but feel a stab of anger and arousal, his body betraying him despite his mind screaming in protest. "You're such a sweetie," she says, her voice dripping with honey. "Now, let's see if there's an upgrade available." The attendant nods frantically, his eyes never leaving her chest. Tim watches in horror as Beverly lets one breast slip out completely, the nipple peeking through the fabric like a tiny pink jewel. She doesn't acknowledge it, just smiles sweetly at the attendant, who's practically drooling. "Oops," she says, her voice feigned innocence. She giggles and covers herself up, but not before Tim sees the glint of satisfaction in her eyes. She turns to him, her hand still cupping her breast. "What do you think, Timmy?" she asks, her voice a mockery of Tracy's sweetness. "Should we go first class?"

Tim's face is a mask of embarrassment and frustration as he watches the scene unfold. He clears his throat loudly, trying to break the tension. "T-Tracy," he stammers, his eyes pleading. "Could you maybe..." He gestures at her chest, but she just laughs, her hand sliding away to let the breast fall out completely. The attendant's eyes widen comically, and Tim can feel his own cheeks burning. "It's fine," she says, her voice light. "It's just a little wardrobe malfunction." She winks at Tim, who can't decide if he wants to scream or die. "Is there a problem, darling?" she asks, her voice still a perfect mimicry of Tracy's.

Beverly's eyes twinkle with mischief as she plays the part of the clueless girlfriend. She tilts her head, allowing her blonde hair to fall over her shoulder and partially obscure her naked breast. She pretends to notice the attendant's shocked expression and gasps, placing her hand over her mouth in mock horror. "Oh my," she says, her voice still Tracy's but filled with Beverly's mischief. "How embarrassing!" She giggles, her free hand playing with the fabric of the sundress. She looks over at Tim, her eyes gleaming with satisfaction. "Could you be a dear and help me?" she asks, her voice a sweet purr. She knows he's torn between his own embarrassment and the need to preserve the illusion. She watches with delight as he fumbles to fix her dress, his face a picture of mortification.

Tim's face is a deep shade of red as he quickly adjusts the sundress to cover Tracy's exposed breast. He avoids eye contact with the attendant, who's trying to keep his gaze anywhere but on them. "It's fine," Tim says, his voice strained. He clears his throat and turns to Beverly. "Tracy, maybe you should..." he starts, but she cuts him off with a look that could freeze water.

"Timmy, darling," Beverly says, her voice still Tracy's but with an edge of her own. "There's no need to be so shy. After all, it's just a little flesh." She winks at the attendant, who's trying his best to act professional despite the situation. She leans closer to Tim, her voice a seductive whisper. "You know you like it," she says, her breath hot against his cheek. She giggles and straightens up, smoothing down the dress. "Now, about those upgrade?" she asks the attendant, her voice a perfect blend of innocence and command. Tim can feel his heart racing, torn between his own embarrassment and the thrill of seeing his sister in his girlfriend's body acting so brazenly. The attendant, flustered, nods quickly and prints out their boarding passes. "Thank you, darling," she says to Tim with a smirk, taking the passes from the attendant. "You're so helpful." She takes Tim's arm and leads him away from the counter, her grip firm and possessive.

Tim's mind is racing as Beverly leads him away from the check-in counter. He can't believe what just happened, but he's also acutely aware that people are staring. He tries to shake off the feeling of Beverly's body against his, the way she's acting like she owns him. "Bev,... Sorry... Tracy" he says through gritted teeth, pulling his arm away from her grip. "We need to talk." He glances around the airport, searching for a quiet spot. "This isn't right," he whispers harshly. "Tracy would never do something like that."

Beverly rolls her eyes, but the smile on her face is still Tracy's. "Timmy, darling," she says, her voice a syrupy sweet parody of his girlfriend's. "You're so tense. This is our vacation. We're supposed to be having fun." She giggles, and it's a sound that makes Tim's skin crawl. She tugs at his arm, her grip surprisingly strong in Tracy's body. "Come on, let's go find our gate."

Tim reluctantly follows, his mind racing. He knows Tracy is a brainy, introverted type, not someone who would flirt so openly in public. But the body language, the way she's holding herself, it's all so... different. And yet, so familiar. He sighs, his eyes scanning the airport for a quiet spot. "Look, Bev," he says, his voice low. "You can't just do whatever you want. This isn't you. This isn't Tracy."

Beverly's grip tightens on Tim's arm, her nails digging into his skin, making him bleed. She stops and whips around to face him, her eyes flashing with anger, though they're still Tracy's sparkling blue. "Don't you dare call me Bev in public," she hisses, her voice still Tracy's but her own irritation seeping through. "I'm Tracy now, remember?"

Wincing at the pain, Tim tries to pull away, but Beverly's grasp is surprisingly firm in Tracy's body. "Okay, okay," he says quickly, his voice low. "Tracy." He uses her new name, hoping to placate her. He can't shake the feeling that she's enjoying this twisted game a little too much.

"Much better," Beverly says, her smile returning to its former sweetness as she releases Tim's arm. She starts walking again, her hips swaying more dramatically than Tracy's ever had. "Now, let's go get some breakfast," she says, her voice a perfect imitation of Tracy's. "I'm positively starving." She pulls Tim towards a café, her eyes scanning the menu with an enthusiasm that's all her own. She orders a lavish breakfast, complete with eggs benedict and mimosas, all the while keeping up the facade of a loving girlfriend. When the food arrives, she picks at it delicately with her long, red-painted nails. Tim notices a drop of blood from where she'd gripped him too hard. Without missing a beat, she brings her finger to her mouth and sucks it clean, her eyes never leaving his. The act is so brazen, so deliberate, that Tim feels a shiver run down his spine. She laughs lightly, a sound that's hauntingly similar to Tracy's, and says, "Oh, I guess I got a little carried away there." She winks, her eyes glinting with a mischief that's entirely Beverly's.

Tim tries to ignore the blood and the way his heart is racing. He takes a deep breath and reminds himself that this is his sister, not his girlfriend. But the way she's acting, it's like she's relishing every moment of this twisted game. He watches as she eats, her movements so unlike Tracy's. She's always been the picky one, but now she's devouring her food like she's never tasted anything so divine. He can't help but feel like he's lost both his sister and his girlfriend in one fell swoop. "Bev, I mean, Tracy," he says, stumbling over the name. "You're not eating like Tracy would."

Beverly takes another sip of her mimosa, the bubbles tickling her nose, and glances at Tim with a smug smile. "Well, Timmy," she says, her voice a perfect blend of Tracy's sweetness and her own snark. "I guess that's the perk of being in charge of this little meat suit. I can do whatever I want, and you can't say a word without looking like a crazy person." She takes a bite of her eggs benedict, closing her eyes in exaggerated pleasure. "Mmm, this is heavenly," she moans, her tongue darting out to catch a stray piece of hollandaise sauce. She opens her eyes to find Tim staring at her, his expression a mix of annoyance and arousal. She knows she's pushing his buttons, but she can't resist the thrill of it. "What's the matter, darling?" she asks, her voice dropping to a purr. "You don't like watching me enjoy life?"

Tim's jaw tightens as he watches Beverly, his thoughts racing. She's enjoying this way too much, and he can't help but feel like a puppet on her twisted stage. He opens his mouth to protest, but she interrupts him with a wave of her hand. "Don't worry, darling," she says, popping a strawberry into her mouth. "I'll make sure to keep the surprises coming." She pulls out her phone, her thumbs flying across the screen. She's about to put her earbuds in, her eyes lighting up with a mischievous glint, when she notices Tim's irritation. She pouts, her lower lip sticking out in a way that would normally make him want to kiss it. "What's wrong, Timmy?" she asks, her voice a perfect Tracy pout.

Tim's eyes follow Beverly's hand as she pulls out her earbuds. The way she's acting is grating on his nerves, but he can't bring himself to be too harsh with her. After all, she's still his sister, and he's afraid of what she might do if he pushes her too far. "It's just... Tracy wouldn't act like this," he says, trying to keep his voice level. "You're being so... bossy." He watches as she makes a face, her nose wrinkling up like it used to when she was a kid and didn't get her way. She takes a dramatic sip of her mimosa, the liquid sliding down her throat, and sets the glass down with a clink. "Well, Timmy," she says, her voice a mockery of his own. "Maybe Tracy needed a little bit of Beverly in her life." She winks at him, her makeup-free eye flashing with mischief. "And now she's got it. In spades."

Beverly rolls her eyes and pulls the earbuds out with a huff. She's had enough of Tim's complaining. "What, you don't like my taste in music?" she asks, her voice dripping with sarcasm. She unlocks Tracy's phone and opens the Spotify app, the bubbly pop tunes assaulting her ears. She makes a face like she's just bitten into something sour. "Oh my god," she says, her voice filled with revulsion. "What is this shit?" She scrolls through the playlists, her nose scrunching up with each new song that plays. "This is all so... peppy." She says the word like it's a curse. "It's like listening to a unicorn barf rainbows." She finds the settings and deletes everything with a flick of her thumb. "There," she says, satisfaction in her voice. "Now we can listen to something that doesn't make me want to gouge my eyes out." She starts playing a heavy metal song, the bass vibrating through the phone's tiny speakers. The look on Tim's face is priceless.

Tim's eyes widen in horror as the heavy metal blares through the phone. He's used to Beverly's taste in music, but this is not what he was expecting from Tracy's Spotify. "What are you doing?" he yells over the noise, his voice a mix of shock and anger. "Tracy doesn't like this kind of music!"

Beverly laughs, a wild, unbridled sound that's definitely not Tracy's. She holds up her middle finger, the gesture obscene and out of place on Tracy's delicate hand. "Oh, but I do," she says, her voice still Tracy's but filled with Beverly's spite. She places the earbuds back in her ears and leans back in her chair, closing her eyes. The music's volume is turned up so high that Tim can feel the bass in his chest. He's torn between snatching the phone away and just walking out of the café.
