Lisanna's POV

"HMPH!" I waddled through town, my blubbery 600 pound body shaking as I looked around for my sister.

As I ran about I felt myself jiggling around a bit, I couldn't wait to see Mira and hear what she thought of how I looked, I was hopeful my fattiness wouldn't freak her out. The others had told me I could probably find her at my grave about now so I was headed there.

"Um excuse me." I walked up to a large Amazonian woman "I'm looking for my sister, do you know if she's here?"

"Hmm, Lisanna?!" she gasped.

"Mira!" I gasped at her face "It really is you!"

"Hmm." She held a disgusted sneer on her face "What the fuck happened to you…disgusting."

"What?!"

Later

Mira's POV

"Come on you fatty run like you mean it!" I scolded Lisanna "No sister of mine is going to live as an out of shape obese slob, I don't know what you were thinking letting yourself get like this but you better start shedding those pounds and bulking up like a real woman!"

"Mira~" Lisanna groaned slowly trudging on the treadmill "I need a break, I'm hungry and sweaty and tired."

"Too bad!" I said lifting some barbells and watching the fat ass run.

"UGH!" Lisanna waddled and ran "So tiring."

"This is why you need to shed those pounds." I told her slapping her belly "They're slowing you down and making you sluggish, once you lose some weight and start looking more like me you'll be perfect and feel great too!"

"You're so mean Mira, I like this body." Lisanna stopped running and pouted, her big cheeks puffing out.

"Trust you're big sis." I laughed pinching her cheeks "This will be healthier for you and you'll feel good, I know it."

"Hmph." She huffed and got back on the treadmill, her big ass shaking and her belly flopping.

"Good." I smiled.

A Few Weeks Later

"Wow I haven't been this skinny in ages!" Lisanna said looking at her once again thin body, a cute sweater hugging her body.

"You lost like 500 pounds in just a few months." Erza noted "Is that even possible."

"Magic food made me grow fast so I guess I magically lose it fast too." She laughed.

"Okay." I said getting the needle out "Are you ready to get buff Lisanna?"

"I've worked hard to look like this." She laughed "So let's hit that finish line!"

"Here we go." I said injecting her.

"HAAA!" Lisanna moaned as the power of the steroids pumped through her body "UGH I FEEL THE POWER!"

Lisanna started to get toned, her deltoids thickening up, her arms slowly getting bigger and buffer as bundles of muscle packed onto her. Her breasts got larger and rounder, her pecs also getting larger and wider, her sweater ripping a bit as she became a goddess of muscular power.

"Wow!" Lisanna flexed her right arm "I feel amazing! Mira this is incredible!"

"You look amazing too." I said rubbing her washboard abs "I hope you don't get lax again, you better try and keep up and get as strong and big as your big sis."

"Oh I will." She laughed as our powerful chests pumped together.
