You wake up to the familiar sound of your girlfriend Miku's cheerful morning greeting. "Miku dayooo!" she exclaims for what must be the hundredth time since you started dating. The routine is comforting - showering together, getting dressed, and stealing playful gropes of her curves that always make her giggle, the warmth of her skin against yours making every morning feel like a new adventure.

Now you're in a private airplane with Miku, heading to Brazil for a much-needed vacation. The cabin smells of her coconut shampoo and the faint scent of the tropical destination you're approaching. When you land, you set up camp on the beach with a portable bed and umbrella Miku insisted on buying, the hot sand burning your feet as you work.

"I'll get us ice cream," you offer, and she responds with a mischievous grin. "If you bring back my favorite flavor, I'll let you..." she trails off suggestively, causing your pulse to quicken in anticipation. Carrying two cones carefully, the sweet scent of vanilla and chocolate mixing with the salty ocean breeze, you round a corner and collide with someone.

You manage to save the ice creams from hitting the sand, but look up to find yourself staring at... Miku? But taller, with a slight sunburn across her cheeks, and curves that seem even more pronounced beneath her tight beach outfit. "Oiii, você é bem fofo. O que te traz aqui, fofura?" she says in a voice that sends shivers down your spine with its unfamiliar accent.

Before you can process this strange encounter, you hear your girlfriend calling. "Babeeee, where are youuuu?" Miku appears around the corner, spots you, then notices the other Miku, her eyes widening in surprise. "Uh, didn't know there was another me in here," she says, her tone impossible to read.

The Brazilian version smirks and gestures toward you. "Oh? Well, what do we have here? Another me and this cutie." Your Miku's expression hardens slightly as she steps closer, the sand crunching beneath her feet. "Oh now, dear, it looks like even another me also likes you. What are you, some sort of Miku magnet?"

Before you can respond, Brazilian Miku wraps her arms around you, pressing her body against yours in a way that leaves little to the imagination, the warmth of her sun-kissed skin through her thin clothing making your breath catch. "Would you like to come to Brazil~?" she whispers in your ear, her accent making the innocent question sound incredibly sensual.

Your Miku yanks you away, her jealousy evident in the tightness of her grip. "Will you stop that?" she snaps, though there's a hint of something else beneath the irritation - perhaps even a touch of arousal at the thought of competition. Now you're caught between two versions of the girl you love, with no idea how to proceed.
