In an AU in which Team 7 discovered that the Bridge Builder's mission was much harder than a simple C rank mission, and decided to spend some more time rescuing lost cats. Zabuza and Haku lived on, and all is well.

Haku never grew into what Zabuza expected. Zabuza wanted a tag team partner, a number two. Zabuza wanted to bring up a student in his image, to carry on his reign as Demon of the Mist when he inevitably succumbed in battle.

Instead, Haku was… Haku. Zabuza did not want to call him a disappointment, because despite his personal preferences Haku was still competent and formidable. At 13, Haku had already graduated from all of the Mist nin's training, but Zabuza was wary to taking him to battle. Instead of growing to the same stature as the Demon, Haku remained rather short and lithe. He could never adequately gain muscle mass, no matter how much Zabuza insisted he eat or how heavy of stuff he lift. His soft, feminine features never turned grizzled, and lord knows that Haku would never be able to grow the same rugged facial hair that hid under Zabuza's wrappings. Even now at 18, the pupil's large doe-eyes sometimes made Zabuza question if he was, in fact, a boy.

Zabuza realized his student's pretty face was nothing but a hindrance to their goals. Female ninja received special training in the art of seduction, using their looks to their advantage. Zabuza wanted none of that for his student, and even if he did he wouldn't know where to begin teaching Haku.

Zabuza gifted a Kirigakure hunter-nin mask to the boy to hide his soft features from enemies. "Why do you want me to hide my face, Zabuza-sama?"

Zabuza wasn't used to his weapon questioning his motives, but mustered up an answer. "We must cover our faces in battle."

"Oh." Haku looked down to his mask in hand, and back to his Sensei. "Why?"

Zabuza was slightly more prepared this time. "So people don't know our true identities."

"But you only cover half of your face, and everyone knows you because of your bandages."

"Just wear the damn mask, Haku."

Zabuza longed for the embrace of a woman.

(Though he would never admit it.)

It was difficult being in his position. He and Haku had to keep moving to avoid detection. If they stopped, they were too busy collecting food and discussing their next plans that neither of them had time to focus on their personal needs.

As you can imagine, it was quite a surprise to Haku when Zabuza dropped his backpack at a seemingly random location in the woods.

"Zabuza-sama?"

"We're going to stay here a few nights, Haku."

Haku nodded, not in a position to debate his master. They needed to resupply anyhow, and Haku could use the break as an opportunity to find some new herbs. He wasn't sure where they were exactly, but between Zabuza's knowledge as an ex-ANBU ninja and the wealth of information they carried with them it would not be too difficult to find out. Haku sorted through his pack for a map, hungry for information on the area. He was interrupted when Zabuza cleared his throat, a very un-Zabuza-like thing to do. The Demon of the Mist announced what he wanted, he did not need to get anyone's attention.

"I'm going into town for a while. Resupply, rest up, and bathe. Take your time, we'll be here for a few days now."

Haku, weirded out by his master's sudden lenience, chose to focus on resupplying before he put thought into his own needs. Zabuza had been in a hurry to leave their camp, which struck the boy as odd. He was seldom alone. It was nice to be able to quietly hum to himself without Zabuza telling the boy to shut the fuck up.

Haku stripped out of his normal garments. The feeling of the cool evening air as he pulled off the thick, wool fabric was a blessing. This land was much warmer than he anticipated, and he felt stifled under the bulk of his usual attire. He let his bun down, dark hair brushing against milky white shoulders and sticking to the sweat dampening the back of his neck.

He felt much freer as he adorned the pink yukata. No question it was designed for a girl, but Haku was comfortable with his femininity. Truthfully, he only dressed this way when Zabuza was injured and couldn't enforce his dress code of baggy pants and face-coverings. The few times he had warn it around a bedridden Zabuza, the Demon nin had been unable to make eye contact with the boy. Haku lived to make Zabuza happy, but surely he could feel pretty while Zabuza was gone.

Haku would resupply. Then, he would consider that bath.

Zabuza's arm hung lazily around the blonde's shoulders, satisfied with his conquest for the night as he led her back to the camp. She was short and fair, with wide hips and rounded breasts. Her blue eyes sparkled, not dulled by the alcohol. Zabuza was surprised, because he could feel himself losing his inhibitions. She certainly was a catch.

To be truthful, she was Zabuza's second choice. The first was slim, with long dark hair and hardly any curves to speak of. She looked foreign; Eastern. She spoke with so much delicacy that Zabuza found himself getting lost in her language. They were sitting close to each other at the bar, and Zabuza was looking for the right time to invite her back. She poured him one last drink from their shared bottle of sake and smiled up at the Mist nin.

Her soft, brown eyes were framed by thick lashes. They were beautiful, and familiar. Suddenly Zabuza found himself looking down at his student. He quickly excused himself.

The blonde was probably a nice lady, Zabuza mused, even if she was letting herself be led into the middle of the woods by some guy she just met. When they made it back to camp, Zabuza quickly started a fire and sat next to the blonde. Cupping her soft cheek in his bandaged hand, he kissed her fiercely.

Haku pouted as he walked back to the camp. He had been looking forward to that bath, but found himself too uncomfortable to enter into the gendered bath houses. He anticipated a co-ed facility, but when faced with entering into the "men's" or "women's" dressing rooms, Haku opted to find a pond somewhere and bathe there.

As he neared camp, Haku was instantly aware of the moaning and whimpering noises. A wounded ninja? Haku questioned as he hid his supplies with a simple genjutsu. Haku stalked his way to the basecamp, back flush against a tree as he peered into the fire-lit opening. He sighed with relief when he saw it was just Zabuza and… who is that?

The blonde woman pulled herself onto his sensei's lap, shrugging off the shoulders of her yukata without breaking their passionate kiss. Her breasts were taught against the night sky, and Haku watched as his master's hands caressed them, pinching the woman's soft nipples. She threw her head back in a moan. Zabuza pulled off her sash, allowing the rest of her yukata slip to the ground.

Haku faced a momentary crisis of conscious. He knew his master would be furious if he knew his pupil was spying on what he was doing, but Haku didn't know what his master was doing. He did know that a heat was growing in his lower belly as he watched the pair. It was new and uncomfortable. Haku slid down the rough bark of the trees to sit on his knees, hips writhing uncomfortable.

The woman kissed her way down Zabuza's bare chest, down to the large bulge in his pants. Haku's breath quickened as the blonde freed his master's manhood. It stood tall and thick. The heat in Haku's stomach burned so fiercely now that he could no longer sit still. Eyes wide, he watched the woman licked up his master's cock. Zabuza let his head fall back, exhaling as he enjoyed the woman's ministrations.

Zabuza was impatient. After a few minutes, he gruffly whispered into the blonde's ear. She smiled and giggled, crawling back onto his lap. Haku watched as though in slow motion as his master gripped her hips tightly, guiding her low. She moaned hotly as he entered her. They paused for a moment, and Haku panicked that his master may have heard him, but after a second she started moving up and down. She threw her head back as Zabuza did most of the work, ramming her up and down on his thick cock.

Without warning, he flipped her onto all fours. Haku could now see the ecstasy on the woman's face as Zabuza thrust into her from behind, holding her hips tightly with one hand while the other fondled her breast.

Haku's drifted from the woman's form to his master's. Zabuza bandages that normally obscured his face now lay loosely around his neck. His face looked so… Haku was struggling to find words. His brain had seemingly gone to mush. Something about seeing his master like this ignited a feeling he didn't know existed. He saw his battle-scarred body every day, but in this context it was so much different. The muscles in his torso rippled and flexed with each thrust.

Haku's gaze trailed over his body and back to his face, where he met the hard stare of the Demon of the Hidden Mist.

Zabuza's look felt less like a "I'm going to murder you for eavesdropping" and more like a "if you walk away right now we can never talk about this again."

Haku spun on his heal and headed to the nearest body of water for a much needed bath.

Haku dunked his head under the cool water, desperate to clear his mind. No matter what he did, the heat between his legs wouldn't subside.

He didn't know what he had witnessed. It seemed sinful. Zabuza had never talked to him about anything like that, but subtle references his master had made suddenly flooded into his mind. When working for Gato, they worked with a team of thugs to ransack a brothel that was under a competitor's control. During the briefing, Haku was curious as to what this "brothel" business was. The men all hooted and hollered when the mission was announced, and it peaked the young Ice nin's curiosity.

"It's a place for adults," Zabuza had explained over lunch. "They do… Things only adults do in there."

"Oh, I see," Haku was satisfied with the answer. He assumed it was like gambling or drinking. After capturing the brothel and killing all of the men inside, Gato's other thugs had talked about what would become of the women inside.

This memory was suddenly so vivid to Haku. Zabuza had grabbed the younger boy's arm and yanked him out of the building, speaking to him loudly about the next mission. Haku wasn't used to his master's touch, and he remembered being flustered by how direct he was.

It made sense now. What he saw his master doing was what those men had discussed.

Haku, still confused, melted into the water and closed his eyes. He couldn't erase the image behind his eyelids. The rippling abdominal muscles, the rough moans of passion, his master's manhood…

The Ice nin blushed, feeling his own manhood twinge with the thought. He may have not known much about sex, but Haku was a teenaged boy. With a breath, he touched his manhood with a delicate motion.

His back arched into his own touch, desperate for release. His breathing grew unsteady and rapid. His right hand continued their ministrations while his left explored his chest.

"Z-zabuza-sama," Haku choked out as he released his seed into the lake. He collapsed, lounging deeper into the water, gasping for air.
