Chapter seven: first heat

Naruto smiled as he took his leaf headplate from Iruka. Even though most of the people in the village was against him in passing and becoming a ninja. He proved them wrong. He was now on the way of achieving his goal. Suddenly without warning, Naruto felt incredibly hot. Naruto could hear Kurama let out a sharp curse as both the transformation and clone jutsu dispersed in a puff of smoke. Naruto noticed even Iruka becoming stiff.

*Kit get home........ NOW!* Kurama yelled mentally. Naruto could feel it much clearer now as he instantly knew that he was going through his first heat. Naruto bolted out to the back through the forest before any alpha males could smell his pheromones. He needed to get home and away from the alpha's. He didn't want the other alpha's to rape or claim him. That right only belonged to Sasuke as Naruto had a very special connection with the younger Tengu. Naruto rushed back to the Uchiha home where the brothers had built a small hut that would serve as Naruto's nest for when he goes into his heat. It was built with special filters that would keep his pheromones from escaping. It was sound proof so no one could hear what was happening inside. It was stocked with water and food in a rather small kitchen, and had a single bathroom with a shower.

Meanwhile...... Iruka reentered the classroom as Sasuke didn't see Naruto. But he could feel through their bond that Naruto was first happy and then went into a panic. That is when Sasuke could smell nod from Iruka.

"Return back tomorrow to find out your teams and who was the rookie and konochi of the year." stated Iruka. Sasuke used the window to escape fangirl horde. Not when Naruto was going through his first heat. Sasuke flew as fast as his wings would carry him as he alerted Itachi mentally about Naruto's heat.

*Remember Sasuke........ Only to help Naruto through his heat. It will be up to Naruto and Kurama if they want to be marked yet.* Itachi replied mentally.

*I know Itachi. I will let you know when it is safe for you to return home.*

*All right Sasuke. Take good care of him.* Itachi replied before he cut the telepathic link with his brother.

Sasuke landed in front of the small hut that served as Naruto's nest. Even though he couldn't smell Naruto's pheromones, he could feel the Kitsune's want, desire, and need for Sasuke. Sasuke gently knocked on the door in a special pattern that would alert the Kitsune to his presence. Sasuke waited a bit before he made some handsigns and bit into one of his fingers to draw blood. The door to the hut could only be opened by either Sasuke, Itachi, or Naruto. After quickly entering the nest, Sasuke could smell Naruto's pheromones a lot stronger which caused the Tengu to feel very hot. His cock instantly sprang to life, pulsing within his clothes. Almost instantly Sasuke knew that he was experiencing his first rut. Sasuke could also feel Naruto's lust and desire much clearer now. Sasuke carefully removed his clothing before he entered the main part of the hut. Sasuke found Naruto laying on a pile of soft blankets, sheets, and pillows. Naruto was fully nude exposing his body to the cold air that circled about the room. Naruto was fingering himself and pumping his cock which was hard, erect, and dripping down his thighs from his ass. Naruto's whimpers and mews grew in volume.

"Sasu..... Please......" whined Naruto. Sasuke stepped into the nesting area hovering over Naruto. Sasuke grabbed Naruto's hands stopping the Kitsune from pleasing himself. This caused Naruto to whimper louder.

"I don't think you realize that by watching you, listening to you, and sensing your need is turning me on." Sasuke stated in a husky voice. Chill danced down Naruto's spine at the sound of Sasuke's voice as the Tengu took Naruto's cock into his hand. He smeared the precum all over the mushroom head. This caused Naruto to gasp out in pleasure as Sasuke closed the gap between them kissing Naruto hard and passionately. Naruto moaned in the kiss as their tongues battled for domination which Sasuke won of course. Sasuke pumped Naruto's cock as the two kissed until they had to break for air. Sasuke took the opportunity to lick and kiss down Naruto's body as when he got to Naruto's very erect member, he deep throat the pulsing organ. Naruto screamed out in pleasure when Sasuke did this. Sasuke began to lick, nip, and bob his head up and down on Naruto's cock.

Naruto threw his head back screaming Sasuke's name as his fingers weaved their way into Sasuke's hair. Naruto tried not to thrust his hips wildly but he thrusted his hips enough to encourage his mate to go harder. Sasuke hummed sending wonderful vibrations on Naruto's cock causing the Kitsune to begin to chant Sasuke's name as the Tengu's fingers entered the warm slick that was pouring out of Naruto's ass. Naruto began to thrust wildly when he felt Sasuke's talons touch a special nerve in his ass. Sasuke smirked to himself when he found Naruto's prostate as he continued to rub the sweet spot picking up the pace on the cock deep throating the erection harder down his throat.

"Ah...... Sasuke....... Ha......." Naruto chanted over and over again. Naruto could feel that he was close to cumming. "Sasu...... Ah....... ~Ngh!....... I'm gonna...... Ha ha...... cum!" Naruto yelled out wildly.

*Cum for me my Kitsune.* Sasuke commanded mentally not letting up his assault. Naruto growled out in pleasure screaming out Sasuke's name loudly of Naruto's warm and salty seed as he let the erection go with a loud pop. Even though Naruto had just came, he was still very erect and hard. Soft purrs rumbled through Naruto as he panted coming down from his high.

Sasuke used some of Naruto's natural luberation and cum to lather up his erection. Sasuke wedged himself between Naruto's legs as he lined himself to enter the Kitsune. Naruto looked at Sasuke with lust in his eyes as he nodded his head giving the Tengu permission to enter. Sasuke thrusted his hard rod deep into Naruto's warm hot ass. Both moaned out loud throwing their heads back. Sasuke because of how warm and tight Naruto's ass felt. Naruto because of how hard and thick Sasuke was. Neither moved as Sasuke waited for Naruto to adjust to his large size.

"Sasuke...... Move....... Please......." Naruto stated. Sasuke did as asked as he moved his hips allowing his member to slide in and out of Naruto. Naruto wrapped his legs around Sasuke's waist to allow the Tengu deeper penetration. Moans, growls, whimpers, snarls, the sound of skin hitting skin echoed through the nest.

"Fuck Naruto......" growled Sasuke.

"Sasu...... harder...... ah...... ~Ngh!...... faster......." moaned out Naruto as he exposed his neck to his mate. Sasuke did as the Kitsune desired as he licked and nipped at Naruto's exposed neck.

"Damn Naru....... you smell so good. Your so hot and warm...... your ass is gripping me so hard." Sasuke moaned as he moved faster and harder. Naruto screamed in pleasure exposing his neck more. Neither one of them noticed a second tail emerged from out of Naruto's tail bone.

"Sasuke..... more....... ah...... please...... faster....... harder....... ~ngh!......." Sasuke picked up the pace as he began to pump Naruto's cock in time with their wild thrusts. Naruto arched his back mewling in pleasure. "Yes...... there....... please...... don't stop...... ah......."

"Shit...... Naru....... Fuck....... ah........"

Both could feel that they were close to hitting their orgasm as they moaned loudly. Sasuke going as hard and fast as he could, Naruto meeting his thrusts as both licked and nipped at each others neck. They could feel the desire and need to mark each other.

"Sasu...... mark me......." Naruto yelled out as he knew that he was going to cum. Sasuke stopped moving looking deep into Naruto's eyes.

"Are you sure?" Sasuke asked. Naruto's eyes flashed to a brilliant blood red. Sasuke knew that it wasn't Naruto but rather Kurama. Kurama nodded Naruto's head before his eyes returned back to their normal blue color. Sasuke moved once again. Much harder and faster than before causing Naruto to cry out in pleasure. "Mark me when you cum my Kitsune." growled Sasuke as he licked and nipped at the hollow of Naruto's neck. Naruto wrapped his legs, arms, and twin tails around the Tengu.

"Sasu....... ah..... ~Ngh!....... please......."

"Cum for me Naru......." whispered Sasuke. Naruto's fangs pierced into the hollow of Sasuke's neck as he came hard in the Tengu's hand. Feeling Naruto tighten as he came and sinking his fangs into Sasuke caused the Tengu to cum as well as he sank his fangs into Naruto's neck. When the two withdrew their fangs coming down from their orgasm, a mark began to spread on their necks where they sunk their fangs.

It was a nine pointed star with a shuriken in the middle and three comma circling the shuriken. The mate mark was red and black. Sasuke pulled out of Naruto's as the Kitsune's soft purrs and pants echoed through the hut. The Tengu laid down next to his newly marked mate by his side as he allowed his wings to cover their nude bodies as they both fell asleep in each others arms.
