Try on the sexiest, most revealing outfit first to see David's reaction

You sort through the pile of clothing Natalie handed you, your fingers lingering on something that makes your eyes widen—a tiny, glittering silver dress that seems more suited for a nightclub than daytime wear. The fabric sparkles under the changing room lights, and you instinctively know it would cling to every curve of your new body.

"Omigod, this one first!" you whisper to yourself, the decision feeling natural despite being so far from Matt's usual careful deliberation.

You strip off your crop top and mini skirt, catching glimpses of your transformed body in the three-way mirror. The pierced nipples, the impossibly narrow waist, the perfect curves—it still startles you to see them. You slip the silver dress over your head, wiggling your hips to get it past your curves. The material stretches like a second skin, stopping just barely below your ass. The neckline plunges daringly low, pushing your enhanced breasts together to create deep cleavage, while the back dips nearly to your tailbone.

"Um, Natalie?" you call out, your voice high and uncertain. "I think I need some, like, help?"

The changing room door opens without warning as Natalie steps in, not at all concerned about your state of undress. "Oh honey, that's stunning on you!"

She adjusts the dress, tugging it lower at the hem and higher at the neckline, her hands casually brushing against your skin. "Try these with it," she says, handing you a pair of silver strappy heels with impossibly high stiletto heels.

You wobble as you put them on, adding another four inches to your height. When you look in the mirror, you barely recognize yourself—the woman staring back looks like she belongs on a VIP list at an exclusive club, not in a Putney boutique on a Saturday afternoon.

"Let's show your friend," Natalie suggests with a knowing smile, leading you by the hand before you can protest.

She guides you out of the changing room, one hand at the small of your back. "What do you think?" she calls to David, presenting you like a prize.

David's mouth actually drops open. He sits up straighter in his chair, eyes darkening as they travel slowly up from your heels, lingering on your thighs where the dress barely covers you, then to your cleavage, and finally to your face.

"Wow," is all he manages at first. Then, clearing his throat, "That's... that's something else, Mia."

"Do you, like, think it's too much?" you ask, twirling in place. The movement causes the dress to rise dangerously high, and you quickly grab the hem, giggling nervously.

"Not at all," David says, his voice dropping lower. "You should definitely get that one."

Natalie claps her hands together. "Perfect! I'll set it aside. Now, let's try some daytime options."

As you turn to head back to the changing room, you catch sight of David adjusting himself in his seat, clearly affected by your appearance. A strange thrill runs through you—part satisfaction, part fear. The bimbo part of your brain preens under his attention, while the last remnants of Matt's consciousness registers alarm at your flatmate's obvious arousal.

"Maybe I should get something more, like, casual too?" you suggest, your voice rising at the end to form a question.

"Oh, definitely," Natalie agrees, already pulling more items from nearby racks. "But let's keep that one. Your boyfriend clearly approves."

"Oh, he's not my—" you start to correct her, but your train of thought derails as she hands you a baby blue crop top with the word "JUICY" emblazoned across the chest in rhinestones.

"This would look adorable on you," she insists. "Try it with these white shorts."
