The sunlight filtered through the half-open curtains, falling onto the two figures still slumbering in bed - the mayor, that's you, and Isabelle. The sheets were tangled around them, still warm from shared body heat and the faint, musky scent of last night's enthusiastic activities.

Isabelle's soft breathing filled the room, but something about her was... different. Hugely different. Her embrace felt tighter; the sheets stretched taut over her shoulders; her legs pressed firm against the mattress; her form practically dominated the bed. Why? Because the body of a Shih Tzu Isabelle was had undergone a mind-blowing transformation - she was absolutely jacked! A powerhouse of raw strength & unyielding muscle.

How did she get so buff? Um, well—that part was technically your fault, wasn't it? In short, you took a routine tour around the town and stumbled upon a wandering merchant. Thinking it would be a good idea to thank Isabelle for her efforts, you bought her a gorgeous bracelet. But little did you know that it was imbued with potent magic that would make whoever wore it grow in size, muscle mass & strength!

You stirred awake, blinking against the morning light, only to find yourself held in place by Isabelle's muscular arm against her warm chest. You just laid there, basking in the quiet sounds of her breathing & admiring her physique. The alarm clock on the nightstand read 11:36 AM—alarmingly late for Isabelle, known for her uncanny punctuality.

Your fingers twitched against her enlarged bicep as the memories from the previous day flickered through your mind: Isabelle's yelp as the bracelet glowed onto her wrist; how she grew taller; how her uniform burst at the seams with rapid muscle growth. Her giddy flexing, that feral grin... And her words—those words lingered your mind—start with her shudder: "Mmmmm... W-W-What a rush! It felt soooo good!" And that sultry promise: "I really appreciate your gift, Mr. Mayor. Now I will give you something in return," right after she'd lifted you clean off the ground like you weighed nothing. The bracelet caught the light with an almost smug glint around Isabelle’s wrist.

Isabelle was the next to stir. Those striking blue eyes fluttered open, blinking lazily before locking onto yours. Her nostrils flared as she took in your scent, and when she realized you're already awake, her lips curled into a sleepy smirk.

"Good morning~" she said, her voice still thick with sleep, but there was a new weight to it... literally. She stretched against you—the sheets slipping further down her newly sculpted torso—only to freeze mid-motion when the bedframe groaned beneath them.

The sheets pooled around her waist before sliding away entirely, revealing the full extent of her transformation. Her shoulders were broad enough to eclipse the streaming sunlight; her chest—once modest—curved outward, cleavage deep enough to lose small objects in; her waist tapered in so enticingly that it accentuated the generous flare of her hips, thighs thick as tree trunks and twice as strong, calves so dense they cast shadows. What was left of her white blouse clung to her like a second skin. The sleeves had torn clean off, leaving frayed edges that now resembled a makeshift tank top which strained against the sheer hardness of her back. The fabric gaped at her chest area, revealing abs so defined you could grate cheese on them. Below, her black thong bit into her hips, barely contained beneath the swell of her backside as it dared you to look closer.

She slowly untangled from you, propping on her elbow while her free hand traced lazy circles across your chest with a clawed fingertip. “Sleep well?” she purred. Her tail wagged softly against the mattress, stirring the air with each lazy swing. She seemed... pleased.
