Lucy's POV
"HMPH!" I pouted.
"What's the matter Lucy?" Erza asked.
"It's not fair, why's Natsu all over Lisanna now that she's back." I huffed "I mean I've got bigger boobies, a better ass and give awesome BJs, so why's he looking at that whale of a girl!"
"Natsu and Lisanna are old friends, she just got back from Edolas a few hours ago, cut them some slack." Erza giggled.
"So, I bet he's gonna fuck her later too." I stomped my foot "First Virgo and Layla, then Wendy and now this, plus you got sexier too! There's not enough cock to go around!"
"Poor Lucy." Erza teased hugging me "Although I do know your pain, hey why don't we head back to the house and you and I will have a little fun?"
"HMM!" I moaned a bit as our boobs pressed together "Okay."
Natsu's POV
"I can barely believe that's what the guild is into." Lisanna said "Even my siblings are almost unrecognizable."
"Yeah." I laughed "You certainly don't look related to them."
"I guess it's because I'm so big right." She patted her belly "Over in Edolas is was all about being big and soft but over here it's about sexy, it's certainly a different look that I don't match."
"Why are you sounding so depressed?" I asked "I don't mind I think you look cute like this."
"You might but I really don't." she sighed "Seeing all the other girls I just feel jealousy of how sexy they look. Even with you I feel different, you're a big muscly hunk and I'm just a fat loser.'
"Stop saying that." I told her "But...if you're so upset about how you look you might as well try the potion, you'd take it to join the guild anyway."
"Okay..." she smiled at me "Thanks for saying those nice things anyway."
Lisanna drank the potion and slowly stared to moan.
"Oh...oh I can feel it...HMMM!"
Lisanna started to change, the fat melting off her body as she slimmed down in size before gaining some major curves, large breasts, plump lips, wide flared out hips and some very meaty thighs, she was very pear shaped.
"Ohh I didn't know it would feel so good." Lisanna moaned hugging her body "Well Natsu, am I sexy now?"
"Yeah, very." I held her thighs as we started making out.
I felt Lisanna's hands exploring my muscles as I laid her on the bed and spread her legs.
"Natsu what are you-HAAA!" she screamed as I buried my head between her legs and started eating her out.
I rapidly flicked my tongue against her clit as my hands held her tender thighs, Lisanna was moaning loudly and rubbing her soft breasts, squirming on the bed as I held her down and munched on her lips.
"You taste good Lisanna." I said dragging my tongue up her dripping folds.
"You sure now how to treat a lady Natsu." She moaned a bit "When did you become such a stud?"
"I'd say around the time Erza started making everyone drink her potion." I stood up showed her my raging boner "Then I grew this thing."
"You're huge!" she gasped "Just looking at it is making me wet, I can't wait any more, fuck me Natsu!"
"UGH!" I grunted a bit and slid into her "So tight."
"HMM I'm gonna split in two!" she moaned rolling her hips as I settled inside of her "Please Natsu!"
I started pumping my hips to thrust into her as Lisanna's breasts wobbled on her chest. My hands were on her wide hips, pulling her deeper onto my cock, her face going wild with pleasure.
"Yes Natsu yes! OHH FUCK!" Lisanna threw her head back and shook with her orgasm.
Since I wasn't done yet I flipped her over so she was laying on her stomach and kept up the pounding, Lisanna moaning as my hands squeezed her plump ass and railed her as hard as possible.
"Lisanna...I think I'm gonna...UGH!" I groaned suddenly blowing my load inside her.
"HAA!" she gripped the sheets as she climaxed again.
We went at it for a little bit longer before laying down, Lisanna resting her head on my chest.
"Natsu that was amazing." She giggled "I can't wait to do it again."
"Of course, but you're not the only girl I'm asked to please." I said rubbing her back.
"I don't care." She reached down and started stroking my shaft.
"MMM Lisanna." I moaned "Even with that potion you can still change, you sure you won't overeat and go back to your other look?"
"I doubt that'll be a problem." She licked the tip sensually "So long as I get some of this yummy man meat I'll be more than satisfied."
