  • You and your girlfriend struggle to get used to your new bodies.

  • Sunlight pours through the open garage door as you blink up at your girlfriend's face grinning down at you.

    "You good down there?" she asks, her voice slightly deeper now but still carrying that playful lilt you know so well. She stretches your arms above her head, making your muscles flex in ways you've never seen before. The way your broad shoulders move under your old t-shirt is... distracting.

    You swallow hard, rubbing at your neck where your skin fuses with hers. "This is so fucking weird," you mutter, and your voice comes out a little bit higher than usual. It's embarrassing.

    "Weird?" Your girlfriend barks out a laugh. "This is amazing!" She pats your chest with your own hands, then freezes. "Oh my god. I don't have boobs!" Her eyes go wide as she presses both palms flat against your pecs. "It's so firm. I never thought being flat chested would feel so nice!"

    You groan, struggling to sit up in her more petite frame. The sundress clings to curves that aren't yours, the fabric tugging against your delicate skin. "Help me up before I faceplant in this damn dress," you grumble, holding out a hand that looks so small it's unsettling.

    She grabs it easily, hauling you upright with surprising strength. "Whoa," she breathes, looking down at where her small hand disappears in your large one. "You're, like, super light now." She lifts you a few inches off the ground just to test, making you yelp.

    "Put me down, you ass!" You kick out with legs that feel too slim, too weak. The motion makes the sundress ride up, and you scramble to pull it back down with a flush. "Jesus, how do you deal with this? Everything's so... floaty."

    Your girlfriend just grins, setting you back on your feet. "Aw, but you make it look cute." She pinches your cheek with your own calloused fingers. "And hey, at least you helped pick out the dress."

    "Yeah, when it was going on your body!" You swat her hand away. "God, you're enjoying this way too much."

    She flexes your biceps, watching the muscles jump under your skin. "Uh, duh? My head is on your body, babe." She runs your hands down your own torso, pausing at the waistband of your jeans. "Do you have any idea how long I've wanted to try this?" Her fingers dip lower, and you see her face flush. "Ohhh, that's new."

    "Hey! Don't do that here!" You try to grab her wrist, but she easily holds you at arm's length with one hand while the other continues its investigation.

    "Relax, I'm just getting familiar with my new equipment," she purrs, her voice dropping into a sultry register. "Mmm, you're very responsive down here."

    You cover your face with her small hands. "I'm going to die of embarrassment."

    She just laughs, but finally relents. "Okay, okay, I'll stop." She steps back and pats her new stomach, then freezes. "Wait. Oh my god. Your abs."

    You groan as she lifts your shirt to stare at your own abdomen. "You've seen me shirtless a million times."

    "Not from inside!" She runs your fingers over the ridges of muscle, her eyes wide. "Holy shit, I can feel them. Like, really feel them." She flexes experimentally, and you watch your stomach muscles wiggle under her command. "This is insane."

    Meanwhile, you're still struggling with the dress. The straps keep slipping off her narrow shoulders, and every time you move, the fabric clings in ways that make you hyperaware of her body. "I don't know how you wear this shit," you mutter, trying to adjust the neckline. "It's like being wrapped in tissue paper."

    Your girlfriend—still marveling at your body—pauses to give you a once-over. "You know, you're kinda hot as me." She reaches out to tuck a strand of hair behind your ear, her fingers lingering. "The dress suits you."

    You bat her hand away again. "Shut up." But you can't help glancing down at yourself—at her—taking in the curve of her hips under the thin fabric, the way her collarbones catch the light. It's... strange, seeing yourself like this.

    A breeze blows through the garage, making you shiver. "Christ, you get cold easy," you mutter, rubbing her arms.

    Your girlfriend watches, fascinated. "Do I? I never noticed." She steps closer, crowding you against the workbench. "What else don't I know about my own body?"

    You swallow hard, suddenly very aware of how close your face is to your own chest. "Back off, you're looming."

    She grins and does it more, using your height to her advantage. "Oh, this is fun." She runs your hands up your arms, then pauses. "Wait. Can you feel this?" She pinches your pert butt.

    "Ow! Yes, asshole!" You rub the spot, glaring.

    "Hey, it's my butt! I should be able to do whatever I like to it!"

    "Unbelievable," you mutter, crossing her arms over her chest. The motion makes you acutely aware of the weight of her breasts—something you'd never really thought about before. You glance down, then immediately look away, cheeks burning.

    Your girlfriend notices, of course. "Getting acquainted?" she teases.

    "Shut. Up."

    "We are definitely exploring this later."

    "Absolutely not."

    "Absolutely yes." She grins, then suddenly sobers. "I can't wait to use this on you". She pats your old dick. She definitely has an erection now.

    "Don't even think about it."
