First time writing erotica, give me tips for what I'm doing wrong here if you have time. Can be tips about making the story sexier or just general writing advice.

Sakura had been an insecure girl, but she was a mostly secure woman.

Having just turned 22 and having been a shinobi for nearly four years now, Sakura would say she was pleased with her life. Therapy sessions had helped her come to grips with Sasuke's defection from the village and Sakura was sure she would bring him back one day. Beyond that, she was shaping up to be an obscenely powerful ninja and the student of the strongest woman alive. Things could be better, but she had no regrets as a shinobi.

Sakura was also happy with her body. Growing up, she hated her flat body. She alternated between panicked dieting to have her body excel in at least one area to desperate soy gouging to trick her boobs into growing. The first made her weak and ill while the second merely failed.

While she was a mess physically then, Sakura was a specimen now. Sakura's intense training as a shinobi and her new high calorie, high protein, plant-based diet had left her trim and bulging in all the right spaces. Almost all of Sakura's training was focused on becoming a stronger shinobi to protect her friends, family, and masters… But some of the training helped her vanity. Her boobs were naturally not large, but her powerful pecs made them stand out more than other flat girls. Her arms were pushed to the point of being visibly defined, but just before the body builder look. Her thighs were massive and ripped with muscle. Her fairly wide hips now supported a huge ass built from exercises that may not have been entirely necessary for assassination. Her only regret was that her abs were not as sexy as she would like. She tried to sustain the ultra low body fat necessary for a six pack, but it quickly became apparent this low body fat made her feel terrible and hurt her performance in the hospital and in battle. Hence, she was stuck with a reasonably sexy, flat stomach as her only regret.

Well… Her only regret beyond her one very forbidden fantasy.

She didn't hate her vagina or anything but… She really wanted to have a cock instead.

She loved her wide hips and other womanly features, but cocks were just so beautiful and majestic, and she wanted one so bad.

She had started dating Choji and had fallen in love with his cock. It wasn't that special. Five and a half inches, pubes unshaved, lasted five to ten minutes; everything you would expect from a typical dick from a normal guy. But even the most ordinary penis could take Sakura's breath away even before she put it in her throat. Their curves, their throbbing, their veins, their powerful and greedy need. She loved cock.

But her relationship with Choji hit a serious snag because she may love cock, but cock in her pussy or anywhere else simply left her wanting. Sakura was a pure top and a greedy lover which she knew didn't appeal to everyone. But beyond that, Sakura simply didn't like topping with her vagina. It was so unsatisfying to her to dom while being penetrated. It could have been gender stereotypes that caused her to feel that way, but she didn't feel like a dom when getting stuck with cock. She knew other girls could and still others could use strap-ons to satisfy that urge, but Sakura personally felt incomplete.

Sakura ended her relationship with Choji amicably but was left lost for several months as she tried to figure out what she wanted sexually. No matter how she thought about sex, her mind came back to dick. She wanted a dick and was sad she did not have one.

It was the only thing that truly disappointed Sakura about her body, and it was one thing that didn't appear fixable.

… Until she came across research by one of Lady Tsunade's students about new chakra manipulation techniques to grow penises in transgender men. Sakura had been reading over research papers about hormone treatments when the title of one work made her jump and scream aloud. After getting over mortifying stares from others in the library, Sakura read over the title three more times to make sure she hadn't misread.

'Chakra applications for genitalia transformation.'

Heart thumping, Sakura quickly read over the abstract.

'The most frequently self-reported cause of gender dysphoria in transgender persons is their genitalia. Prior gender affirming care on genitalia for transgender patients relied purely on non-chakra surgical intervention due to the high probability of chakra rejection near sexual organs. Our work puts forward a new technique of chakra blending to avoid chakra rejection. Blending the patient's chakra with the chakra of a third-party who has the desired genitalia for the patient allowed us to perform gender affirming care for transgender patients using chakra. The treated transgender male clients managed to develop testicles with functional sperm, could quickly gain and maintain erections in their penises, could ejaculate from their new penises, and the penis length developed could reach or exceed the average cis male length of five and a half—"

"I need this, I need you," Sakura muttered, hands shaking. She knew she should marvel at the incredible technique used and maybe focus on her job and certainly feel very pleased at the superior care now available to transgender patients. And she would later, but as now…

"I need you so bad."

Despite Sakura's need, it took her another two weeks to gather up the courage to talk to Lady Tsunade about this. She felt embarrassed to ask for something that wasn't helpful to her as a shinobi and was so advanced that it would take a serious amount of time that Tsunade didn't have. It also was very awkward talking about sexual things with Tsunade, given their relationship. It was even more awkward to talk about her deepest and darkest sexual desire with Lady Tsunade. So, Sakura researched and thought and stewed and eventually concluded that she needed to talk to Tsunade about this.

"Come in, Sakura," Tsunade said as their appointment time came up. Sakura had been anxiously waiting outside of Tsunade's office, trying to calm herself for the last 20 minutes. Taking a few more shallow breaths, Sakura entered the Hokage office with trepidation.

"Thank you for your time, Lady Tsunade," Sakura said as she bowed deeply, trying to stop her nervous ticks, and mostly failing.

"Sakura, we've known each other for years, cut the shit and tell me what's wrong," Tsunade asked, looking concerned at her desk.

"Lady Tsunade, I apologize for my recent behavior, I… I recently read this article and I was wondering if… If you could help me with something," Sakura mumbled as she quickly brought over the research paper.

"Sakura, are you trans?" Tsunade asked after reading over the piece. "You don't need to worry if you are, I'll protect you from any hate you may receive, and I'll help you for everything you need."

"No, I'm way fucking dumber than that," Sakura said, head tilted to the ground, face red. "I… I just really want a penis. I have a cock fetish and not having a cock has hurt my sex life and this is so fucking stupid, I'm so sorry."

"Sakura," Tsunade said as she stood up from behind her desk and walked over to her to place her hand on her student's shoulder. "Your master is a woman who has invested a good bit of time into making sure her tits and face don't sag like they should at her age and that her skin looks way nicer than it actually should. Sex and vanity matter a lot, it's not stupid."

"Thank you, Lady Tsunade," Sakura asked, trying to fight off stupid tears.

"And yes, I can give replace your reproductive system with a more traditionally masculine reproductive system."

"You can?!" Sakura exclaimed, raising her face to look at Tsunade's friendly smile before immediately lowering her face back down out of embarrassment at Tsunade seeing her teary eyes.

"Of course I can," Tsunade scoffed. "I worked with Ichika on that paper, I just didn't put my name on it as I wanted her to have work that she could claim on her own. I'll be happy to do this for you."

"Thank you so much, Lady Tsunade!"

"And you just want a penis and testicles, no other hormonal or body changes?" Tsunade asked as she retreated back to her desk.

"I understand that having a penis and testicles that function will require some hormonal changes—"

"In the past, yes, but a lot of interesting research has introduced hormone balancing and compensation seals we should be able to use to give you a functioning penis and testicles without changing much else of your perceived internal chemistry."

"That's fantastic!" Sakura gushed, another weight off her shoulders. "But, uhh, yes, I just want the penis and testicles and other needed parts replacing my current reproduction system."

"Can do," Tsunade said, smiling and reaching over to hold her student's hand. "Do you want to still be considered a woman or non-binary?"

"I still view myself as a woman… Do you think that's weird?" Sakura asked, eyes turning to the ground.

"Everything is weird, especially with gender and sex," Tsunade laughed. "If you think you're a woman, you are a woman."

"Thank you, sensei," Sakura said, choked up with emotion.

"We'll schedule the operation for a month from now. Take the rest of the day to think about the dimensions you want for your new dick and take some time to celebrate having a master badass enough to do this, but I except you back at work tomorrow at 6 AM sharp. Understood?"

"Yes, Ma'am!" Sakura said as she rose from her chair, bowed deeply to her sensei and tried to walk instead of skipping out of the room.

Sakura absolutely adored her penis.

She knew other women loved their vaginas and she felt sympathy for women who didn't have the vagina they wanted, but she just had felt like something was missing. It felt like a socket to be used and Sakura wanted to be the one doing the using.

Her currently hard cock was covered in powerful veins with a healthy purple head peeking out from her foreskin. The neatly trimmed pink pubic hair and hairless balls balanced out the over-the-top masculinity that the dick presented. It was a fusion of the masculine and feminine with a lean towards feminine and Sakura couldn't be happier.

She had to admit that she had gone overboard with the size choice, but the size was just so thrilling. When soft, Sakura had a nice and thick four inches that was cute but also warned of a monster to come. When getting hard, Sakura would reach a healthy six inches that people would be impressed by. But the ideal was for bottom bitches to have their breath taken away as she swelled further to a full, monstrous, eight-inch beast. Her massive balls, twice the size of normal guys, also served no purpose except bigger loads to dump on the faces of boys, but they looked oh so nice.

Sakura giggled as she lightly jumped up and down, her pole bouncing in a way that demonstrated its sizeable weight. She desperately wanted a boy to fall to his knees and immediately find his new God in her pants and she almost came thinking of Sasuke coming back for her dick.

Her fantasy began to fade as the reality of her situation set in. Sakura realized that dating now would be more difficult as many guys just weren't into penises and even more guys definitely weren't into blowing dicks. Some would find her penis weird, and some would be very turned off by her penis or turned off by it being so big. She was also doubtful that the men she liked were bottoms. But while dating would be hard, she just liked her body so much now. And that was worth the cost.

Just six weeks after Sakura had gotten her new penis, another void was filled. As she jogged around the exterior of Hokage Tower on a work break, Sakura noticed unmistakable blonde hair nearby. After jumping up into the air with her fist held high, Sakura ran over to Naruto. Naruto took just a moment to realize Sakura had noticed him and responded with a shy but pleased smile.

"It's so good to see you, Naruto!" Sakura yelled, lifting her friend off the ground and above her head with ease while Naruto squawked. Laughing, Sakura set Naruto down.

"Geez, Sakura, you've gotten stronger," Naruto wheezed, trying to mentally recover from what just happened.

"That's what happens when you work with the strongest human alive," Sakura answered back with a smirk, lightly flexing her noticeable biceps with her hands on her hips. "When were you planning to let your teammate know you were back?"

"I had to go see Lady Tsunade first, Sakura," Naruto whined. "You know that I would prefer to see you first."

"Hmmm, I think I believe you," Sakura said, looking him up and down. "But don't leave me waiting again, got it?!"

"Yes, Ma'am" Naruto gulped, his reaction causing blood to inconveniently start flowing faster to Sakura's dick.

If Sakura's smarter head was in control, what happened next likely would not have had happened. But her lower head was powerful and…

"Sakura, will you go on a date with me?" Naruto asked, hand behind his head, looking sheepish and ready for an attack.

"Yes, absolutely, how about tonight?" Sakura answered.

The date had been awkward to say the least.

Both seemed to be thrilled and regretful for the date occurring and the conversation was… frequent to end. They had gone to a wonderful sushi restaurant that they could not enjoy too much due to the circumstances and were currently finishing a walk around one of Sakura's favorite gardens. Neither had spoken in several minutes.

What made the date more awkward was that Sakura was basically dying of thirst.

Sakura loved to masturbate, especially to the thoughts of topping Sasuke or Naruto while Sasuke and Naruto made love to each other. But having the real deal Naruto with his distinct and unbearably cute features right there… Being able to smell and touch and potentially fucking pound into the floor this Naruto… Her boner was desperate to actually penetrate this Naruto instead of retreating to her hand and her fantasies.

This led to the next layer of awkwardness in that Sakura was doubtful Naruto would be willing to bottom for her. She had caught Naruto staring at her ass and muscle definition a few times and Naruto's eyes even had drifted down to her not remarkable tits once or twice. So, she knew Naruto very much liked the parts of her body he could see… But Sakura's excellent work tucking meant that he was in the dark about one important feature.

They continued to walk in silence for a moment, Sakura trapped in her head until her dumber, more aggressive head took command and took a huge risk once again.

"Let's go to a hotel and… let's fuck," Sakura said, her voice trembling with need.

Naruto head whipped towards her comically fast, staring intently at her, looking for any sign of a joke. In response, Sakura just bit her lip, looking at Naruto's beautiful face like a predator approaching an elk.

"Uhh, uhh, yeah, sounds good," Naruto mumbled. "Uhh, which one?"

"Hang on," Sakura said, grabbing his hand and immediately beginning to run to the nearest sex hotel she knew.

Sakura likely would have felt embarrassed at their desperation if she could think of something other than her erection. Whether the receptionist gave mocking glances at her and Naruto as she led them to their rooms is unknown to Sakura. What Sakura did know that she wanted to fuck.

"Shirt off," Sakura commanded as soon as the door closed. Naruto fumbled with his clothing for a moment before Sakura growled in frustration and simply tore his clothes apart.

"Shaved, fuck yes!" Sakura said, as she began sucking on his nipples and led Naruto to the mattress.

"Holy, holy shit," Naruto moaned as Sakura shoved Naruto to the bed and started licking down his lightly defined but delicious abs. Sakura licked like a madwoman, tearing Naruto's pants apart as well at the same time. Naruto's cute fox boxers did distract Sakura and make her coo for a moment, but the boxers came off quickly too.

Naruto's dick was desperate, leaking, and much smaller than hers. It looked roughly around the normal size of five and a half inches, so Naruto had nothing to be ashamed about, but Sakura couldn't help feeling deliriously proud of her big dick as she looked at Naruto's tool.

"How do y—" Naruto started before Sakura absolutely inhaled his dick into her throat. Her control of her body made deepthroating easy. Sakura knew most preferred a luxurious blowjob where the cocksucker made out with the cockhead for a good length of time before deeper penetration if the receiver could handle it. But Sakura wanted to show Naruto who had the power here.

In the end, Naruto's poor dick didn't have a chance. Sakura's hands tightly grasped Naruto's fabulously firm and bubbly ass and she went to town. Her head moved at rapid speed, briefly stimulating the cockhead before shoving his penis right back to her tight throat. Naruto's penis held out… for thirty seconds… As Sakura felt Naruto's dick twitch rapidly to signal an upcoming orgasm, she quickly pulled his dick from her mouth and began rapidly jerking him with her hands. Just seconds later, Naruto's dick erupted over her hands. Sakura donned a cocky grin as she watched Naruto's face ahegao.

"I'm not bad, right?" Sakura asked the drooling, cross-eyed, flushed, gasping for air boy on the bed. Standing, she walked over the nightstand and used the tissues there to clean her hands of Naruto's cum, tossing them to the bin after. Sakura knew now was her shot and went for it.

"So, Naruto, I had… some body modifications done while you were gone," Sakura said, playing with her tuck, her big girl throbbing with frustration. "I… I hope you like her."

"What do you mean?" Naruto asked, breathing heavily, but finally processing something other than his orgasm.

"I'm still a girl, but I decided that instead of a vagina… I wanted a big fucking cock," Sakura answered, undoing her pants and underwear, and letting her dick swing free. Her words were confident, but her heart was pounding in anxiety. Naruto was even hotter than she thought, and she really loved him. She wanted to fuck this cute guy so badly, but would he—

Sakura's fears went away as she saw the drool start up again from Naruto. She began to sway her hips as she walked towards Naruto, his eyes locked onto her tool as she exaggerated her movement to make it move. Every step and every glance lowered her anxiety and raised her hunger.

"So, you like?" Sakura asked, lifting the dick to Naruto's face. "Pretty boys like you often do."

"…Pretty?" Naruto asked with a blush. Sakura couldn't help but break her dom persona to squeal.

"Oh, fuck yes, you are so fucking pretty. God, your hair is so beautiful, I love how fucking cute your whiskers are, your eyes are just *gorgeous*, those cute pouty lips, that look of determination you have that still shows the shyness you have to overcome. And that's not even getting below your neck, fuck, I want to fuck you so bad, you're so pretty."

Naruto's deep blush somehow became even redder as his cock rose to attention once more. Naruto tried to turn his head away in seeming shyness… But this failed as he couldn't keep her eyes off Sakura's simply huge dick.

"… How big?" Naruto asked in a quiet voice.

"Eight inches long, seven inches thick," Sakura said, hands on her hips as she rocked her hips back and forth to give Naruto a show. "She's a big, big girl."

"Geez, it's like you're out of one of Pervy Sage's books… Except it's… beautiful too."

"Aww, thanks," Sakura replied. "Now, she really wants to play with you. She knows she's too big for your cute little mouth right now, but she would really like it if she could rub against your beautiful face. Is that okay?"

"Yeah," Naruto said, gulping but keeping his focus on her dick. "Yeah, I would like that too."

"I've jerked off so many times thinking about this," Sakura said, grinning hugely as she flopped her dick onto Naruto's head.

"It's so warm and… hard," Naruto answered. "I know that's what dicks are like but… Yours is the first on my face."

"Honored," Sakura answered. "You're doing great, cutey, but if you want lick or kiss anywhere… That would be highly appreciated.

"Am I really that cute or do you say this to everyone you cockslap?" Naruto responded.

"My cock really does make everything look better, but yes, you're extremely cute even without my cock all over you. We just went over it this, not going to repeat myself when there's cock you could be appreciating. "

"How about you tell more reasons why I'm cute and I'll start liking up and down the shaft?"

"Fine," Sakura puffed before laughing. "I love your cute, firm ass, I want to grab it and spank it and squeeze it and fuck it. I love how you're willing to transform into a cute girl and play around with your gender, that's a huge turn-on for me-OH GOOD BOY, keep licking! I love how hard you work and how much you care about not only me but others. And I love how much of a cocksucker you seem to be, you are such a good boy!"

Naruto was blushing deeply as Sakura played with his hair. Sakura bit her lip and started playing with tits as her crush took his first cautious licks of cock. Naruto licked all the way down her penis, stopping for several moments to appreciate her comically large balls. Sakura became worried that Naruto would be grossed out by how large her testicles were, but then Naruto began licking all the way around her balls.

"Oh, thank fuck you like my balls, I was really worried," Sakura admitted, causing Naruto to stop for a second.

"They're beautiful, how could anyone not love them?" Naruto asked, holding her testicles and marveling at the weight, drool starting to appear on the side of his mouth that made Sakura quiver.

"And they're going to make you the prettiest boy in the world very soon… Who am I kidding, you're already that, but I want you covered in my cum," Sakura moaned as a dark red Naruto began licking his way back up her penis, approaching the drooling head.

"Hmmmm, should I give this leaky penis a big kiss?" Naruto asked, putting his pointing finger to his chin, but ruining the effect slightly by grinning.

"Oh, no, you don't get to tease me right now, subby," Sakura growled. "You don't get that right until you're my beautiful boywife wearing your anniversary lingerie… Or until our third date."

"Wife?" Naruto asked suddenly, causing Sakura to panic.

"It's just a dumb sex fantasy and joke, I'm really sorry about bringing it up. Not that you aren't great, but we've had one date and—"

"Wow, you get a dick and suddenly I'm the one with brain," Naruto laughed before puckering up and giving an exaggerated kiss to Sakura's other head.

"I will let that go as you are way too fucking cute and good at this," Sakura squealed. "Please use your tongue on my head and taste my precum."

"Yes, Ma'am," Naruto answered, taking his first licks of precum as Sakura moaned in satisfaction above him. "Not a bad taste… This is so much though."

"It's just an appetizer," Sakura chuckled as she regained some sense of control in the pleasure. "My massive balls fucking love you and have been desperate waiting for you."

"It's too bad you couldn't tell me before I got here or I would have trained my ass for you," Naruto said before trying carefully to put Sakura's cockhead into his mouth, gagging instantly. "And my mouth too…"

"You don't need to rush at all, Naruto," Sakura said, ruffling Naruto's hair. "Our sex life for a while can just me being blowing you while you play with my dick. I don't know if we'll ever get my dick inside you."

"We will get that dick in my ass," Naruto said in his classically determined voice, making Sakura smile and her cock pulse.

"Could you jerk me off, baby? I want to cum so bad on your beautiful face."

"Yes, Ma'am," Naruto answered as he began to pump her dick.

"Fuck, you're so much better at this than me," Sakura gasped. "Baby, close your eyes, I'm going to fucking douse you in cum."

Sakura fucking unloaded on Naruto, cum covering the Naruto's face, chest, hair, and neck. She felt nothing but ecstasy as she came all of Naruto's sexy body. Her joy was only enhanced at Naruto let out surprised squeals over Sakura's third, fourth, fifth, and sixth shots of cum.

Panting, Sakura more closely looked at her handiwork and swooned. Naruto's eyes were thankfully closed, but he had left his mouth open and tongue extended. A decent amount of cum had landed on his tongue and fuck, that was so hot. Sakura had had many huge cumshots before with her dick, but this was easily the biggest. She wished she had a Sharingan right now to sear this moment into her brain forever, but settled for soaking in it for several moments, lazily tugging at her softening dick.

"Umm, Sakura, can you help?" Naruto mumbled awkwardly through his tongue placement.

"Oh, sorry, baby, I'm sorry, you were just too hot," Sakura stammered, rushing over to grab some tissues before cleaning off Naruto's face.

"Am I boyfriend material at least?" Naruto asked with an awkward smile around his tongue.

"You are fucking wifey—I'll stop saying that, I'm really sorry—Yes, I really want to be your girlfriend," Sakura said, pausing her cleanup of Naruto to embrace him in a hug and deep kiss.
