Rei was mulling over a missing part in his fuinjutsu when he heard the door to the room open. He raised his head and froze, his throat going dry, making him gulp. He just realized... today, both him and Konan are fifteen!

Konan walked inside, swaying her hips as her privates were covered in underwear made of paper. Her steps were purposeful, slow, focused to give him show and emphasize her curves. Konan wore her typical make-up as she stopped three meters in front of Rei and leaned forward, giving him a look at her cleavage, her hands behind her back. ​​

Rei could see her eyes sparkling, expecting his reaction as both stared at each other.

"..." Rei stared at her with his mouth open.

"..." Konan stared at him, her lips curling up.

"Paper...seriously." Rei deadpanned, making her face-fault.

She sprang up to her feet.

"What! It appeared the most natural!" Konan shouted while pouting sullenly.

"I am sure." Rei snorted, averting his gaze, trying to hide his snickers.

Konan sat on the edge of the bed with a huff, crossing her arms.

Rei chuckled and approached her, he put his knee between her legs and cupped her chin, dragging her face to meet his as he embraced her.

Rei looked at the small woman in his arms. She was barely 5 feet 3 inches tall and while he was not that tall either, her head was barely reaching his chin.

He smiled and put his chin on the crown of her head, his hands on her hips.

"How are you feeling?" He asked tenderly.

"I love you." She blurted out, somewhat helplessly but then her body relaxed as she somehow found amusement in the situation and released a small giggle.

"And here we are. I wanted to seduce you yet it is you who are doing the seducing."

"Well, at least you are cute." Rei told her, making her widen her eyes and before she could give some cheeky reply, he claimed her crimson lips.

Their lips separated as Rei pulled his head away from her.

"Ne?" He gave her an eye smile, only to feel his long braid be grabbed by Konan and pull him towards her as she started trailing pecks on his lips while her hands snaked around his neck, pulling him closer to her.

Konan jerked her body backward, making her back fall onto the bed while pulling Rei with her.

Rei smiled at her as he stored his clothes into a storage seal on the bracelet around his wrist.

"Are you sure you want this now?" He quietly asked Konan. He knew she was prone to be hasty when it came to these things.

"Be gentle, okay?" She timidly nodded and spoke in a mouse-like voice.

"I wanted nothing else for years." Konan whispered with a longing, desire-filled voice.

She started kissing the crook of Rei's neck, and her hands started slowly scratching his bare back.

Rei was momentarily distracted until he felt her teeth nibble on his collarbone. He was now assured that Konan really wanted this and wasn't about to let her be in the lead.

Rei pulled his body backward, into a sitting position while Konan's hands instantly tightened her hold around his neck, pulling her body upwards, trying to get into his lap.

Rei held her around her waist with one hand, helping her body rise as his second hand made the girl yelp when it took a handful of her ass to help her up. Konan didn't hesitate and her legs ended locked behind his back.

They made out until Konan decided she had enough as she felt Rei's stiff member pressing on her butt. She raised her body and lowered herself, stopping only when she felt the tip of his penis slightly spreading her slit.

"Ko-"

Before Rei could continue, Konan pushed his entire length into herself, her embrace tightening as she felt the pain of losing her virginity. She took a deep breath and started moving up and down. She was kunoichi. Small sting like that won't stop her! Not when she waited years for this!

Rei was bewildered. Konan just took his virginity so fast he didn't even manage to blink! He bit back a laugh and decided. If she wanted to play it this way, then sure. He will oblige!

His left hand touched her lower back, pushing raiton chakra into it, sending a jolt of pleasure through her spine, making Konan straighten up with a squeal.

She glared at Rei for that and her hands grabbed Rei's hips, sending her suiton chakra, making his body instantly relax. He didn't lose control but with his body loosened like this, it was hard to move and Konan was in the charge.

Konan pushed his upper body back, making it fall onto the bed as she straddled him, rocking her body back and forth while panting. Rei felt her wet and warm walls as her body begged for release. Releasing his own suiton chakra into his system, he regained the control and quickened the pace, putting his hands on Konan's thighs sending his lightning chakra to her nerve endings, up her thighs, making them all tingle with pleasure. He could see Konan's body stiffening, coiling, as instead of continuous panting she was now releasing sharp breaths. She was almost there. Rei continued. His chakra was climbing up her thigh through her nervous system, flaring every nerve ending it encountered, and when it finally reached her nether regions... the nerve endings in her pussy, Konan squealed in a high-pitched girlish tone as her slit started gushing out juices while Konan's body was continuously shuddering in delight.

Rei felt himself being gripped in crushing fleshy walls, feeling Konan's warmth, he couldn't resist and released a hot moan as he climaxed inside of Konan.

He felt Konan's body fall onto his, still shivering in ecstasy. They laid there for five minutes like that when Konan started moving again and Rei pulled her head up, kissing her.

Their night only started. They had much, much more chakra and energy to spare for this much awaited night!

...

They were at it for six hours straight, until all lust was filtered out of their system by sheer tiredness and the wetness around them. The sheets were drenched in their mutual juices, mixing together.

Konan looked at Rei's head that rested on her chest. She was... proud. She made her man exhaust himself so much, he was unable to move! It made her giggle as her fingers coursed through his hair. She loved his long hair as her fingers could swim in them, feeling the silkiness. At times, it made her jealous but Rei always made sure to compliment how he absolutely loved her neck-long hair.

Konan was looking at Rei's drooping eyes and sighed in absolute satisfaction as she could still feel his seeds deep inside of herself. It made her so glad that Rei made that anti-pregnancy seal. She wouldn't want to lose this feeling due to caution!

Rei felt... proud. No, really! How many men could say they went blow fo-, ahem, orgasm for orgasm with the girl of their dreams!

His cheek was sinking in Konan's modest but very comfortable chest as he felt Konan's fingers massage his scalp. Konan hummed as she cared for him. He could feel how much of a warm goo her body became and was actually impressed she could move her hand through his hair. He could still feel on his belly how wet her crotch was and how her muscles were relaxed. He wondered if either of them would be able to move tomorrow as their muscles reached their limit in the third hour of their lovemaking due to the excessive use of fine-controlled elemental chakra they pushed through themselves.

But... as with explosives, if it ain't working, you ain't using enough.

Konan just pushed more suiton chakra into Rei's muscles, relaxing them to keep going in her desire-driven pursuit for his body while Rei pumped her nerves with his raiton chakra as he didn't want her to stop looking at him with such a loving devotion in her eyes.

They knew well this was not the smartest approach. When your muscles are about to give up... you probably should not force them to continue for hours. Rei was sure their bodies gave out somewhere between the fifth and sixth hour and neither could move anymore. Konan's nervous system was screaming in pleasure at her to NOT put more raiton chakra through it and Rei's muscles stopped working no matter how much he wanted them to continue. Their minds… were far too gone long ago.

Somehow, neither wanted to lose this connection. They could feel their souls embracing each other as they had sex and it brought them to new heights of mental high. Konan just used her paper to move while Rei used his fabled chakra strings! In the end, they stopped at the end of the sixth hour as even their chakra gave out. Their bodies completely numb as a slight pleasurable ache ran through their entire beings.

Neither regretted taking this step as both knew they desired it greatly for years. Now... they were finally one.
