Lucy's POV

I woke up the next morning and saw Natsu was still a girl.

I really wonder what happened.

"Good morning Luce." Natsu said siting up.

We got out of bed and I got dressed. Since none of Natsu's male clothes fit I had to lend him some of mine, but since his boobs were bigger than mine not everything fit well. The sweater I lent him was stretched out over his breasts. While normally long on me it exposed his midriff. I wasn't letting him break my bra so he was going out without one. The jeans he was able to get into without too much of a problem.

"You look cute." I complimented making him blush.

"Thanks…" he said as we left to go to the forest and visit Porlyusica for some answers.

Before we left we decided that if anyone asked Natsu's girl form was named Natasha.

The entire walk there Natsu was mostly quiet except for a few complaints about how his chest was bouncing with every step. I explained that normally a bra would take care of it but none of mine fit him.

We arrived at the old woman's tree and knocked.

"Hello?"

The door opened and the woman looked at us before slamming the door in our faces "Beat it."

"Wait." I said stopping the door "It's an emergency."

She looked back "Nothing looks wrong with you."

"It's not me it's Natsu." I said pointing to the girl next to me.

The woman scanned him and sighed "Come in…"

We took a seat and she asked what happened. We explained that we were having sex and Natsu suddenly turned into what he was now.

"I'll have to do some tests." She explained "Both of you get undressed."

Natsu and I complied and the old lady began her tests. She started with Natsu, poking and pressing various parts of his female body. She took a blood sample and came to me next. She did the same thing, squeezing and fondling parts of my body. It was a struggle but I kept myself from getting a boner in front of the old woman. She took a blood sample from me as well

"I need a sample of something else Futanari girl." She said handing me a cup.

I got the message and headed into the bathroom to provide the needed fluid. I locked the door and took off my pants. I started rubbing one out but I was having trouble getting a load out.

I peeked my head out into the room and the woman was doing tests at her desk while Natsu sat and waited.

"You done girl?" She said without looking.

"I'm having a little trouble." I said "Can I Uhh…barrow Natsu for a minute?"

"Whatever gets me the sample?" She said.

I waved Natsu over and he walked into the bathroom.

"What's the matter Luce?"

I lifted the sweater up quickly causing his boobs to go up and flop back down with a smack.

"I'm having some performance anxiety. I need you to help me." I explained placing my dick between his large breasts.

"Okay." She said pressing her boobs together.

"Spit, I need something to lube it up." I said placing the collection cup on the counter.

Natsu obliged and got his cleavage all moist.

"There we go." I said as I started thrusting into his breast "Move them up and down."

Natsu started bouncing his large chest up and down sending waves coursing through me.

"That's it Natsu, these things are so big and soft." I said.

"It feels so good." He said "Having a hard thing like you in-between my soft pillows."

I keep calling him he and she…I need to get a hang of that.

"I'm almost there Natsu…" I said.

"Come on Lucy she needs that sample." Natsu cooed.

"HAAA!" I started cumming and shot thick ropes of semen into the air.

They came back down and landed on Natsu's breast covering them in white sticky fluid. I scooped up enough to fill the cup and there was still some left on Natsu.

"Here you go." I said placing the cup down for the woman.

"Sit tight it will be a while." She said.

"Okay."

I walked back into the bathroom to get my pants and found Natsu sucking his own nipples and licking my cum off his breasts.

"You naughty girl." I said closing and locking the door.

"Lucy!" Natsu said "I'm sorry it just looked so good."

"It's fine Natsu." I said making him face the counter "She said it would take some time so let's pass it with some fun."

I pulled the jeans off Natsu and slid the panties I had lent him off and wasted no time penetrating him.

"Lucy!"

Natsu and I were animalistic as we fucked in the bathroom. I slammed into him as he watched himself in the mirror.

"Do you like that?" I asked "Watching yourself getting fucked!"

"I look so hot!" he said "You feel so good Lucy!"

There was a knock at the door "When you two filthy people finish up I'm ready to present my findings."

"Alright!" we both yelled.

"I'm almost there Natsu."

"Lucy I can feel it!"

We both climaxed at the same time and I covered Natsu's back in warm cum. We got ourselves cleaned up and went out into the office and took a seat.

"So." Porlyusica started "This happened due to and interaction between Natsu's Blood and Lucy's Futanari Semen. The two reacted and caused that."

"What about turning him back?" I asked "Can it be done."

"Yes." She said "It's quite simple actually. Get up Natsu."

The girl complied.

"I want you to think hard about your male body. Remember what it looked like and think about having it back."

Natsu scrunched his forehead as her thought and suddenly started glowing like he had last night. His hair shortened and he got taller. His breasts disappeared and his muscles returned. Natsu had turned back to a man.

I'm kinda sad.

"I'm back!" He cheered.

"We're not done yet." The old woman said "No think about the female form and want that body."

"Huh?"

"Just do it!"

Natsu thought and started glowing again. His body went through the same changes as last night and Natasha was back.

"What the!"

"Just as I thought." The old woman said "You've gained a magic that lets you freely change between male and female."

"That's...useful." I said as Natsu shifted to a man.

"Good problem solved now get out. Oh and another thing." She said "He has working female parts so use protection. Lucy I need to speak with you for a moment."

I went over to the coner with the woman.

"Listen because you are a Futanari I wager your semen is also what mad Levy's breast grow. I don't know if the same thing will happen if another person gets your semen on them so be careful."

"I will."

"Thank you Ma'am." We said leaving the tree.

"It's good to be back." Natsu said.

"Hey Natsu?" I asked "Did you like being a girl?"

He thought about it "I'd be lying if I said I didn't like it. It was interesting and I kinda liked that body."

"Well since you can change back and forth it's no problem. Also you're still wearing my clothes so…"

"Oh!" Natsu said changing to Natasha.

I'll never get sick of watching that change.

"We need to get you some outfits for your female body since you male clothes won't fit." I explained "Let's go shopping!"


Natsu and I walked the streets of Magnolia. We decided if we saw anyone from the guild Natasha was just a friend I had made. We were keeping Natsu's new powers a secret.

"First things first." I said pulling the man-girl towards a store "You'll need bras and panties."

Natsu was visibly embarrassed to be in the store. We got a booth and a consultant came in.

"Someone needs to be measured?" She asked and I pointed to Natasha

I need to remember to call him Natasha to others. I can call him Natsu myself but others need to think he's someone else.

Natsu took off his sweater and his breast jiggled around. The woman took various measurements and said she'd be back.

"Don't worry I'll show you how to put a bra on." I said reassuringly.

The worker brought in a bra she said would fit Natsu and I told her I'd help the girl put it on.

"Whoa!" I yelled

"What?" Natsu asked.

"You're a G-cup. That's bigger than me."

Natsu covered his breasts in embarrassment "Oh."

"No It's okay embrace it don't be embarrassed you have a smoking hot body. Now let me show you how to get a bra on."

I took my shirt and bra off to demonstrate. Natsu held up her bra to follow along.

"First put your arms through the holes."

Natsu did that.

"Next reach back and connect the clasps."

Natsu struggled with this part but managed to get his arms back.

"Umm…got it."

"Alright now adjust the straps to make them comfortable."

Natsu straightened out the straps and his breasts jiggled around as he did.

"That feels right."

"There we go you're getting it." I complimented.

"Okay now reach in and make sure everything is where it belongs." I said adjusting myself.

Natsu fiddled around with his large breasts until I told him everything looked good.

"If you have to bend over to make sure they're in right. Alright smooth out where you need it and you're done."

"That's it?" He asked.

"Yep it's just a few steps. Okay you stay here and practice I'll go get you some more to try on."

"More can't I just have one?"

"No there are a few bras every girl needs."

"But I won't be a girl all the time."

"Yeah but it will be good to have spares. You'll need a few normal bras. You're active so you should own a sports bra and it won't hurt to have that one sexy number." I said walking out of the booth.

"Please don't get anything too embarrassing." He pleaded.

"Don't worry. You just stay in there and practice while I pick some out."

I wandered around the store looking at bras for Natsu.

She'll need about three normal ones. A sport and a lacey.

I picked out the normal ones first. The one the worker had brought was a plain white one so I picked up and blue and a red one. I found a pink sports bra to match her hair and ended with a baby blue lacy number. I picked out matching panties for each one.

I headed back to the changing room and peaked in the door to see how Natsu was doing. I saw him put the bra on without too much trouble. After he had it on Natsu looked at himself in the mirror. He ran his hand through his hair, spun around and smiled.

He looks happy.

"I'm back." I said letting him know I was here "Checking yourself out?"

"Oh…" Natsu blushed "Well if I have the ability to use this body I might as well get used to it."

"That's good. I like Natasha she's cute." I told him "Here try these on."

Natsu tried on the blue one and then the red one, they both fit great.

"Okay here try this." I said giving him the sports bra.

"This one's different." He said "How do I put it on?"

"It just goes over your head." I explained "Like a shirt."

Natsu put the bra on like a shirt and adjusted it.

"It fits you perfectly. Last one." I said handing him the lacy one.

"Lucy I said nothing embarrassing."

"Come on every girl needs that one special bra."

"Fine." Natsu grumbled taking the light blue bra.

He but it on and he looked gorgeous.

"Perfect."

I went and paid for the bras and brought the white one back to Natsu so he would have some support while we did the rest of our shopping. Next we went to a clothing store to get new shirts and pants. Natsu picked out most of his own clothes and went into the changing room.

The first outfit as just a tight shirt and a pair of jeans.

"I've always wanted to say this." Natsu said tuning around and looking over his shoulder "Do these make my butt look fat?"

"Yes but in a good way." I said.

Natsu tried on a few more outfits and I made him get at least one skirt. I tried to get him to try a dress.

"I'm not ready for that yet." he said "Just the skirt for now."

We went to a few more stores and Natsu bought a few different outfits. When we were in the last store I saw something Natsu just had to try on.

"Please Natsu." I pleaded holding the bikini up to him "You don't have to buy it just try it on."

I was holding a blood red two piece with a flame on the right cup. The top was big and would cover most of his breasts but still leave plenty to the imagination.

"Fine. But you're gonna have to show me how to put it on."

Natsu and I went into the dressing room. He got the bottoms on now problem and got his large chest into the cups.

"Lucy can you tie this for me?"

I knotted the strings behind his back and Natsu looked at himself.

"Hmmm."

"What do you think?" I asked.

"I like it…It's cute. Let's buy it."

We completed our purchases and had to carry multiple bags.

"Umm Lucy?" Natsu asked "Where am I gonna keep all this stuff. I can't have it at my house Happy will see."

"I hadn't thought about that." I said "Oh wait! The apartment next to mine just opened up. You can rent it out and use it as Natasha's house."

"That'll cost me a lot of money." He said.

"You built your own house and save most of the money from jobs you can afford it."

"I guess."


We rented out the apartment in Natasha's name and got all the clothes sorted. Natsu had changed back to his male body while we got the things put away.

"Any time you want to be Natasha just come here and get changed. Oh and here." I said handing him a bottle of pills.

"What are these?"

"Listen this is important. These are Birth Control pills. If you going to be Natasha you have to make sure you take them. I don't know what will happen if you get pregnant so you need to use protection."

"Alright."

"I'm going back to my apartment I'll see you later okay, and remember Natasha is a secret no one can know."

"I know." He said and kissed my "I'll see you later."

I headed back to my apartment and locked the door.

Shopping was fun. I hope Natsu likes all those things we bought.

I walked over to the back wall and looked at a crack.

"Virgo!"

"Yes Princess?"

"Can you make a pin sized hole in the wall here?" I asked.

"Of course." Virgo poked the wall and a small hole formed "All done."

"It's perfect Virgo."

I gave her a kiss and sent her back to the spirit world. I looked through the hole and I could see into Natsu's room. He was walking around and sat on the bed that came with the apartment.

Natsu glowed and changed into Natasha. He took his clothes off and laid on the bed. He ran his hands over his body and when he hit his lower regions he put his fingers inside himself.

He's masturbating as Natasha!

I lowered my own hand down my pants and fingered myself as I watched.

"Ha….ha…ha…" Natsu was panting as he put his fingers in deeper.

"Keep rubbing yourself." I mumbled as I watched.

Natsu groped his large breasts as he rubbed his pussy.

"HAA!" Natsu hips went up as he orgasmed "HAAA!"

I felt myself cum with him and I bit my lip to stifle my moan.

He loves this new form. I wonder if it will happen if I cum on other guys?
