The Punishment

Ichiru sat on his king-sized bed, one hand was resting on the white sheet and the other was holding a remote. His legs spread out revealing a glorious crotch hidden underneath tight blue jeans. Lavender eyes were filled with passion as they were admiring the erotic view in front of him.

His beloved pet brother was sitting on the floor facing him, wearing only strict leather locking anal plug harness, his restricted cock stood on all its glory for his sight's content. Zero's hand skillfully stroke his erection, pre-cum was leaking from its tip, wetting his experienced fingers. His eyelids were closed, hiding his lustful eyes. Gorgeous face was filled with a mix of desire and pain as pressuring blood flow from his testicles to the penis was restricted by the cock ring. Zero's pain was Ichiru's pleasure, Ichiru's heartbeat was increasing from excitement.

"Look at me and spread your legs wider! Show me what I have taught you!"

Zero's eyelids opened, his lustful lavender orbs gazed intently at his master's eyes. Knowing the effect of his licentious body on his brother, he slowly and seductively spread his legs until the outside of his thighs met the floor while his wet fingers were intently stroking along his length, repeatedly touching the sensitive spots around its head. His lips parted, breathy voice spoke seductive words the way he knew his brother liked it.

"Aaahhh… Master…. I feel so good… Please… take me …"

"Not yet, Pet. You have been very naughty."

Ichiru pressed the 'high' button on the controller, turning the butt plug vibrator inside Zero to a full speed.

Rrrrrrrrrrrrrrrr

"Aaaaahhhh..!"

Intense vibration suddenly surged inside Zero's anal cavity, vigorous tingling sensation was poking his prostate, sending the silverette to topple to his side in a fetal position. One of his hands instinctively reached out to his covered entrance, his buttocks tightened in an attempt to reduce the surge but it gave the opposite effect, the tighter his muscles were the deeper the vibrator penetrated, sending shivers down Zero's spine. He needed release, he felt like the pressure in his prostate was exploding yet the cock ring blocked its flow to his penis. Zero slowly and painfully looked up, his face was covered with sweat, plead was clear in his eyes.

"M-master… I… need… to… come…"

"You can't come yet, do you think I will let you come that easily after your rendezvous with Kaname?" Ichiru faked a cold tone, his face was expressionless but inside his heart was beating fast. Punishing Zero always excited him, especially when his brother was begging to come. Zero's shameless expression was a delight to see because he knew that kind of expression was only for him, he was the only one who could give Zero the pleasure that he needed.

Ichiru pressed another button, causing the cock ring at the base of Zero's penis to vibrate fast. Zero pulled both his legs closer to his chest, his whole body was burning, he started to hyperventilate because the restricted pleasure was too much for him to handle. Tears started to wet his pale cheeks.

"I'm sorry…. I… won't… do it… again…"

Ichiru studied Zero's face and saw regret in those beautiful eyes. He knew Zero was truthful but he didn't want to let him go yet, he needed Zero to prove full submission to him, after all Zero was his pet. Besides, his own arousal was in great need of his brother's attention.

"Do you want me to make you come?"

"Yes, Master…"

"Come here and suck me."

Zero slowly pushed himself up off the ground on all fours and tried to hold his body weight with his knees but failed, the vibration on and inside of him were too great his legs were shaking, he went down even before attempting to crawl.

"What's wrong?"

Two sets of lavender orbs met, one was amused the other was lustful and in pain.

"Please… stop … I can't… hold it… any longer…"

"You are this needy just from vibrators? You are so lewd, Nii-san. I can't let you go just yet, but I will relieve you a bit."

Zero's discomfort became more bearable when the cock ring stopped vibrating and the butt plug rubbed his passage in a slow steady rhythm.

"Thank you, Master."

He slowly crawled forward until his face was between Ichiru's thighs. His skillful fingers eagerly unzipped the tight jeans and slid both the jeans and boxers down to the ground, earning a sigh of relief from his brother. Zero took Ichiru's length in his mouth and sucked it vigorously the way his brother liked it, one hand was gently rubbing Ichiru's balls and the other was caressing his inner thigh.

Ichiru felt in ecstasy as Zero's skillful tongue was teasing the sensitive spot under the head of his penis. Head thrown back and eyes closed, both his hands gripped the bed sheet tightly as if his life was dependent on it.

"Haahh… Nii-san… your tongue… so good…"

Pleased with his master's reaction Zero took the hard shaft deeper and sucked faster, Ichiru's buttocks tightened as he felt his release at the tip of his penis.

"Nii-san..!"

Ichiru screamed at the top of his lung as his white juice filled Zero's mouth. The older twin swallowed everything and removed his mouth from Ichiru's now semi-hard cock. He looked up expectantly, finding his brother's eyes still closed.

"Master…. Was it good? Do you like it?" he asked carefully.

Ichiru was taken back to reality, his eyelids opened reflecting satisfied lavender orbs. One of his hands reached out to touch Zero's cheek, his eyes were looking at his lover with so much love.

"Yes, you are fantastic."

Long fingers caressed the soft skin along Zero's jaw line until they rested on his chin, pushing his face up. Ichiru held out his free hand, the older twin embraced it and slowly lifted himself up and crawled to the bed, sitting on the edge of the bed with his bare back against Ichiru's chest.

Ichiru glanced at Zero's lower body and gently rubbed the restricted hard length.

"You are still hard, Nii-san. You like it when I touch you like this, don't you?"

His thumb rubbed the sensitive nerve around its head.

"Ngggh…"

Zero instinctively spread his legs, his testicles came to view.

"Or you like it better when I touch this part of you?"

Ichiru traced the nerve under the shaft until his fingers reached the balls and rubbed them gently.

"Aaahhhh…."

Zero wiggled his hips and rested the back of his head on the crook of Ichiru's neck.

"Please…. Master… do it to me…"

"Very well, Pet."

Ichiru released Zero's balls and grabbed the remote, switching off the vibrator inside Zero, earning a sigh of disappointment from his pet for the lost of sensation. Zero looked up, confusion was in his eyes.

"M-master…?"

Ichiru chuckled, his hand was suddenly in front of Zero's face, dangling a familiar-looking key.

"Don't you want me inside you?" He teased his lover.

"Yes." Zero's eyes sparkled.

"Then you know what to do."

Zero positioned himself on the bed on all fours, his legs spread wide apart revealing tight blossoms. A surge of joy filled his heart as he awaited his reward.

"I am ready, Master." His voice was seductive.

Ichiru could no longer hold his passion, Zero's full submission ignited the burning desire to connect their bodies. He impatiently unlocked the lock and unbuckled the harness, sliding it non to gently down Zero's legs and throwing it to the ground. His eyes met with a plugged hole, the sight was so erotic that his shaft hardened for the second time.

"Aaaaahhhh…." A moan escaped Zero's lips when the butt plug was slowly leaving his hole, its grids were rubbing along his wall in the process. His legs suddenly felt weak like jelly, a deep sense of loss hit him as the plug left his fully-stretched hole. He was getting anxious, he needed Ichiru to fill him now or he wouldn't survive another minute.

"Beautiful…" Ichiru said as he was admiring the pink wall inside Zero's entrance.

He inserted all his fingers inside and slowly rubbed along the wall.

"Your pink hole is so lewd…"

"Nnghh…."

Ichiru's fingers went deeper to massage Zero's prostate.

"Aaahhhh…."

Zero arched his back, an electric-like current filled his whole body.

"Your hole is so ready for me."

"Yes, Master. Take me now…pleaaaasseee…" Zero's voice was desperate, tears filled his eyes.

Ichiru took out his hand and positioned his erection on the entrance.

"I am taking you now, my love."

He penetrated deeply in one thrust, Zero's anal cavity fit his shaft perfectly. He was in paradise when the warm cavern squeezed his manhood.

"Haaahh... Nii-san... I love your hole. It is taking me in deeply."

Thrust. Thrust.

"I love your cock, Master. It feels so good inside me."

Zero pushed back, lifting his buttocks higher so he could receive his brother deeper. He wanted to receive all of Ichiru's, he wanted their bodies to connect deeper, because they were originally one, and when their bodies connected their hearts also connected.

"Aaahhh... Master... harder..."

Ichiru gladly complied, for a moment forgetting their master-pet relationship, he gripped Zero's slim waist and slammed his length harder, causing Zero to see stars.

"Oh, Nii-san…"

Ichiru was at a loss for words, his lover was receiving him so deep, the tight cavern was massaging his most sensitive spots. Zero was a great lover, he just knew how to make him feel at his best. Ichiru felt so happy to have his brother as his lover, who willingly desired to be his pet, proving how much Zero loved him. Zero was his, and he lived for Zero.

"Nii-san… I'm coming…."

One of Ichiru's hands reached down to the base of Zero's penis and removed the cock ring.

"Can I come too, Master?"

"Yes, Nii-san. Let's come together."

The twins rocked in sync with each other, their hearts were beating as one.

"Master... I am coming..."

"Call my name, Nii-san."

"Ichiru... Ichiru..."

"Yes... Like that… Aaahh..."

Ichiru gave one last thrust, sending Zero and himself over the edge.

"Ichirruuuu...!"

Zero arched his back as he climaxed, spurting his juice on the white sheet.

"Nii-saann..!"

Ichiru embraced Zero as he released all his passion inside. He lied on top of Zero and held him for a long time, savoring their closeness. When his manhood went entirely limp Ichiru regretfully pulled out and lied next to Zero, turning his brother's body to face him.

Happiness filled them just as in their childhood times, the two of them lying in bed facing each other, looking at each other with deep love and caressing each others' cheeks. Who would have thought that their brotherly relationship would turn to this?

"Who do you belong too?"

"I belong to you, Master."

Ichiru smiled. No one and nothing could separate them.

"Good boy."

Ichiru affectionately stroke Zero's hair and pressed their foreheads together.

"I love you, Zero."

"I love you, Ichiru."

Their lips met for a long deep kiss.

The End
