Hi!
Here is the third part. A typical scene.
I hope it's not boring. I hope you'll like it.

PLEASE, tell me what do you think of it.

Third Part : Demons, that's what they were

They looked at each other, panting. They took heavy breaths, eyes locked, unconsciously baring their teeth. They could feel their hearts pounding hard in their chests... They could smell each other's scents, which were now become familiar to them, becoming intoxicating to them. They could also feel… their still hard cocks. So hard. Bathed in cum. Rin swallowed hard, hands still laid on his heated groin, still gasping for air. His brother slipped his hands under his, and stroked their lengths with his thumbs through the totally soaked material.

"Fuck me.." Rin said weakly. "Please fuck me now…!"

Amaimon smirked. Letting his hands slide under Rin's, he pulled himself out of the pants, releasing his dripping hard cock, which was bulged with pleasure.

With an amused grin, he slowly bends toward the half-demon and put his arms on his sides to stroke them gently, while his shaft was brushing against the younger's crotch.

The latter shivered. He couldn't take it anymore. This endless teasing was unbearable. His body was looking for more contact on his own: his hips were lifting, begging for more, his tail was desperately pulling on the elder's waist. How desperate…

Amaimon was having fun. He liked this play. He liked his role.

He brushed his lips against Rin's chest. Kissed his stomach, kissed his ribs, going up to his nipples, and kissed them, sucked on one of them, gently first, then harder. Rin moaned, definitely in pain. He stopped, glanced at him, and finally moved to face him. The boy was gasping, swallowing hard. He slipped his arm under his shoulders, nuzzled his nose on Rin's nose.

"Shhh.."

He lifted his little brother up, held him against his chest, then took him in his arms. He carried him, rocking him.

"Shh… I'm here. It will be soon over … Isn't it funny?"

Rin groaned in response. It made him chuckle.

He put him down on the chair, half-sitting, half-laying, legs spread. The boy directly grabbed his arms hard. The demon leaned toward his face, nuzzling against his nose again.

" There, there… What's wrong, my baby brother?"

Rin captured his mouth.

"..hn.. Fuck me..." He answered while kissing and nipping at his lips.

Amaimon was letting him playing with his mouth as he wanted to, allowing him to suck at his lips and press them between his teeth... Until Rin nipped too hard and really bit his lower lip, making him bleedi. He couldn't stop nipping. The blood that was flowing… This scent… was driving him mad.

The elder pushed him back brutally. He really had to master his younger brother. This one was totally overwhelmed with his instincts… although… that was kind of cute, for a young demon.

He held him strongly to the back of the chair with his forearms, cupped firmly his cheeks, and slowly approached his bleeding mouth of Rin's one, offering it to him. This one tasted the red lips, warily. He looked at Amaimon while kissing them. It seemed this one was okay. So, he began to suck at the lower lip, enjoying the warm liquid that was dripping from the cut. He drank it with delight. After a while, the demon pulled away, making the younger groaned.

"Hush… my baby brother" he said in his ear, cautiously moving his hands from his face to slide them on his neck, his chest, up to his hips. "Hush…"

He slowly grabbed Rin's pants, and started to remove it. The half-demon, who was now feverish, lifted his pelvis to help, and shivered when he felt Amaimon stroking his tights in the process. He was free of his clothes, at last.

The elder stood up and removed the rest of his clothes to, looking down to Rin with a smirk. He came closer and put a hand on the younger's lower abdomen to secure him. Then, carefully, he took the boy's drenched length in his free hand and started to pump at it, slowly. He had to hold his belly tight to keep a total control. He then slide his cock in his hand too, against Rin's one, and pumped at them together, slowly, repeatidly.

"ah..! ..ni-san.."

Their shafts were slippery, wet with the warm whitish liquid, and were producing more and more precum.

"ahh !"

Amaimon slowed down.

"What is it.. my baby brother ?"

"Help me…. stop it !..."

He didn't stop.

"What do you need, otouto..?"

"I.. need.. you.. inside of me…" He said, blushing, out of breath.

Amaimon smiled. Awesome little demon brother.

"Shh.. It's okay.. I'm here…" he answered.

He let go of Rin's belly, and massaged their cocks with his two hands to put all their fluids on his own member, then progressively let go of his brother's length.

He put his hands on his hips. He took a look at the half-demon. This one was still totally aroused, but now he was terrified at the same time.

"Don't be afraid" he said, positioning himself between his spread legs.

He leaned toward Rin's face and started to lick his cheeks, gently. In a kindly way, to comfort him. The latter nuzzled at his face in response and instinctively licked him back.

"Relax, my baby brother.. Just relax." he murmured at his ear.

Their tongues met and melted together. Amaimon's warm tongue plunged deep in the young demon's mouth, making him choke. At the same time, he was slowly pushing the wet tip of his length at his tight entrance. Rin put his hands on his brother's chest and tried to push him back roughly, but this one was strong and put an arm behind his back to keep him close, while his other hand was holding firmly his hips. He felt the hot and wet tip smoothly sliding inside of him just as his brother's tongue was sliding into his mouth and throat. He was totally trapped. The older demon was slowly coming inside of him, holding him firmly, a hand on his hips, an arm on his back, his tail around his waist. As he was deeply kissed, Rin relaxed a little. Actually it was fine. It was good to be hold so closely. He felt protective in his arms. For now, just for now, he was really considering Amaimon as his brother.

The elder was slowly pushing himself in Rin's warmth, cautiously. He was careful not to hurt him (he was taking his big brother's role seriously). They didn't say any word. The room was only filled with wet sounds, choking sounds, and heavy breaths.

He was now fully inside of him. Rin moaned in his mouth. He pulled out his tongue and kissed his lips, before leaning his forehead against his.

"I'm inside of you, my baby brother…" he murmured, panting.

The younger gasped. He had tied his arms around Amaimon's neck, and was pulling him closer, needing to feel him, to smell him. This one kissed his cheekbones where some tears were flowing.

"Go on… Ni-san" Rin said weakly.

Still resting his forehead on Rin's, Amaimon began to move, slowly, containing his wild urges.

"Shh… It's okay, it's okay…"

After a moment he pulled out and suddenly thrust back in. Rin screamed of pain and pleasure. An unknown pleasure. He made it several times, and then started to thrust in a regular pace. It was hurting him but it felt good at the same time, better and better, and this mix of pain and pleasure was delighting him. His tail wounded itself around the small of Amaimon's back.

"Hn..! h.. harder…" he said.

Amaimon obeyed, he couldn't keep his self control. He thrust wildly in the warmth, in the tight, so tight, passage, sliding in and out roughly, gliding with ease in the cum of their previous orgasms, while moaning on Rin's lips. This one was grabbing his hair, looking him in the eyes. Tears were running down his face, but he was baring his teeth in a hungry way.

"Ha..! more..! ni-san !"

Without pulling himself out, Amaimon carried him in his arms and pinned him strongly against the wall, and thrust, thrust again inside of him, in the tunnel that was constricting his cock.

"Ni-san…! Ni-san…!"

Rin couldn't think anymore. He was looking Amaimon in the eyes, his lustful eyes that were just like his, smelling his familiar odor, he was feeling his painfully hard cock rubbing on his chest, and this intense systematic pleasure deep inside of him. It was fierce, and that was what he needed. It felt good. It felt so damn good. He liked to see Amaimon making imperious moves into him, fucking him roughly.

"Ni-san…! I… Ah!"

Amaimon felt his brother constricting hardly around his cock, and with that he instantly came, realizing hot spurts of semen deep inside of him.

A moment later, still inside of Rin, he carried him carefully on the chair. He kept on thrusting lightly, communing with his baby brother. This one was completely dazed, dizzy, but he was still stroking Amaimon's hair. They were nuzzling instinctively at each other face.

Animals. They were just like animals.

HE was just like an animal.

But never mind… That's what he was.
