Warning Lemon in this chapter, you have been warned. It's also yaoi so if you don't like don't read.

Naruto hugged Sasuke tightly not wanting to let go as he purred and growled possessively. Sasuke looked back at his friend his eyes wide and he blinked softly,
"Dobe?" he asked. No answer, just the purring and growling. Something was definitely wrong. "Dobe answer me!" he said, that time there was a small response.

"Go…. Before I hurt you…" it was small, timid, but was Naruto's voice. Sasuke shook his head, "I won't leave you until you tell me what's happening."
"It…" was the only reply before Sasuke was turned and Naruto looked at him. His cheek scars were deepened and his eyes were red but misted in lust. He looked like he did before he got his demon cloak but Sasuke was more worried from what he had said.
"What… the…" he whispered before he was kissed roughly and fell down with Naruto on top of him.

Sasuke moaned when he felt something pressing against his stomach, he guessed what it was too. Naruto was in heat! Of course, he was going to want…. It…. Naruto looked up at him and leaned up pressing his lips to his, Sasuke's lips were so cold! And his own so hot, it made the perfect clash, and he didn't care about Sasuke's gender. All Naruto knew is that he wanted him. And him only! Nobody else could have his Sasuke. With a small moan he arched his back up and he licked the Uchiha's lips. Unknowingly the raven-haired boy opened his mouth and immediately a steaming hot tongue entered his cavern. The pale boy moaned at how hot Naruto was, everywhere it seemed was steamy, and so delish too. He opened his eyes slowly and saw that Naruto was purring as he licked around Sasuke's mouth. He was totally content to take the dobe now, he had liked him since they had started but Naruto had always called him Teme and was angry with him 24/7. With a small grunt the Uchiha turned his little fox friend and then started to open his shirt, he wanted some action too.

The blonde felt that he was becoming the Uke but didn't mind and he arched his back to allow his seme easier access to taking off his jacket and shirt. Panting lightly as he did he looked over at his friend, "Aah…. It feels so good" he moaned for his new partner.

"Good," the raven head said smirking softly. Licking around the new skin of his chest, landing on his erect nipple, he licked the bud tenderly and received a jerk from his partner in return. He was sensitive there, ooh this was going to be fun.

In one hour they had nipped, licked and sucked on almost every part of their body. Sasuke was finally into the mood as he stroked Naruto's erection. It was so big and plump he couldn't help it, stroking and rubbing he sighed at how his little kitsune reacted. He was panting and shaking letting out little gasps and moans here and there. His dobe made the best little purrs and growls that only he could make. Sucking on his neck softly he felt his partner tap him softly with a claw.

"Hn?" he questioned softly.

"Sasuke…. I want to do it." He whispered and looked at him his eyes glazed over with lust.

"Alright, we'll do it dobe." He replied stroking his cheek smiling gently. The smaller of the two sighed softly and leaned into the pale ones touch.

Slowly as to not hurt him or startle him he rolled the little kitsune over and laid him down giving him a small neck massage to relax him. He sighed closing his eyes and purred loving it like the Teme thought he would, suddenly three fingers came in contact with Narutos mouth. He somehow knew what to do and started sucking softly on the three dejects, after licking them all around lubricating them fully he let them go. Sasuke kissed his neck softly as he started pushing the first finger in, a small whimper coming from his small kitsune under him. After Naruto had gotten adjusted to the first finger another was added, and then they slowly started scissoring back and fourth, small moans and squeals coming from Naruto's mouth. A third finger started piercing in and another arch of Naruto's back. He panted hard as he clung to Sasuke's shoulders, the pain was bearable, and he knew that Sasuke was doing this for his own good, without this he would of started bleeding or worse. After a while the fingers suddenly disappeared and he blinked confused. Then suddenly he felt it... something was poking right next to his opening and it was big. He gulped softly wondering if he could handle it, closing his eyes he nodded to Sasuke who slowly and gently went into him. He growled and whimpered at times mewing when Sasuke finished going all the way. Sasuke wasted no time and started softly and slowly to pump in and out. His little dobe gasped and panted clinging to the floor with his long nails, he groaned and shivered. Everything turned white when Sasuke thrust, it sent huge pleasurable shivers into his spine. "AAAH!" he screamed loudly and arched up, "Do it again!" he begged panting. His teme obliged.

After mass thrusts; that included teasing words, groans, and a few concessional screams from the Dobe they both released. Panting leaning next to each other they grinned softly and hugged each other, "I wish you were in heat more often." Sasuke panted softly,

"I will always be in heat for you…." The dobe replied. Sasuke looked at him.

"….Again?" he asked, Naruto grinned

"Yes."
