I had thought we were close to victory against the Persians. I had already killed more than I could count.  But they kept coming. 

All around me, swords clanked and shields warbled against spear thrusts or hard sword blows.  Screams of the wounded and dying filled the air.  

The sun baked our naked skin and the smell of blood filled out nostrils.  I looked around of the next foot soldier to slaughter.  I saw one charge at me with his spear lowered.

I grabbed his spear as he got within range, and I broke it with my sword.  Holding the forward end of the weapon, I drove the spear into his stomach and my sword into his chest.

That's when it happened.  As I pulled my sword from the dead man's chest, I felt the cold steel tip of a spear enter my back and force it's way through my stomach.  

I arched back as the spear burrowed through my.body and saw it's bloody tip emerge from my navel.  I screamed in pain and grabbed the exposed shaft. 

Being a true Spartan warrior, I spun around to face the man who had started my death.  He looked young, maybe in his twenties like me.  His face was frozen in fear because I'm sure he hadn't expected me to turn.  He was close, and I swung at him.

His exposed belly split open like a fish, and his entrails fell the ground.  He shrieked in pain until I stabbed him in the neck.  Blood poured from his mouth and he gagged as he fell to the grass.

I hacked his head off as he thrashed about.  Suddenly, I felt the sting of an arrow bite my nipple and lodge in my rib.  I looked down at my pecks and snapped the arrow off near the skin.

I felt myself weakening as I fought, the full spear still inside me.  I saw an older Persian soldier run for safety as I charged at him.  I was surprised by three more arrows entering my stomach.  

I stopped my charge and sank to my knees, looking at my body.  I was in perfect shape, a fine specimen of what a Spartan ought to look like.  I couldn't help but admire the thick spear shaft and tip sticking out of my navel.  

In my leather pants, my penis ached.  I was hard, and my erection hurt inside my pants. I pulled down my pants and let my opponents see my manhood. 

I grabbed the shaft of my penis and the shaft of the spear and began to furiouslly beat off until another, heavier arrow slammed into my chest.  I fell backward, snapping the spear and driving more of the shaft through my belly.

Blood invaded my mouth and poured over my lips. My penis shot its full load onto my stomach as I clutched to the last moments of my young life. Here I was, barely twenty years old, and I was dying.  I would await my wife and children on the other side.  As I coughed blood into my nose and eyes, I stared into the beautiful blue sky. My final, conscious act was to hack at the back of a Persian soldier's ankle and cripple him.  I heard his cries as he fell and my world turned to blackness.

From The Belle Starr Story 1968

I had nothing to live for anymore. No family, no real relationship, shitty job... The only thing that made me happy anymore was pushing knives and other sharp weapons deep into my belly button. I could always count on that to make me cum.

My apartment was filled with broadswords, katanas and rapiers.  I had longbow arrows hanging on my wall. I just wanted to leave this fucked up world I was in. The question was, how would I do it? 

My mind flashed to a video I'd watched some weeks before of a Japanese man committing hara kiri for bringing dishonor to his family.  I didn't know if I had ever gone so far as to dishonor my family name, but the way he did it looked cool. 

But the poor bastard had cut his stomach open below his navel.  Whatever I was gonna do, I'd want that to be my first point of entry.  I considered setting up my longbow with a remote control to fire the arrow. What if it malfunctioned? Didn't want that.

I looked around the living room, and my eyes settled on an orange dragon headed Japanese tonto, the smallest of the three swords carried by Japanese warriors.  

I walked to the TV cabinet and picked up the weapon, a twelve inch knife with gold inlay around the handle.  I walked to the center of the room and quickly undressed. Now entirely naked, I placed my hands on my hard stomach, the tonto clutched in my right hand.

I sank to my knees and held the sheathed blade up.  I pulled off the scabbard and looked at my reflection in the perfectly polished blade.  Using my left index finger, I began playing with my belly button, arousing myself.  

With my cock thoroughly hardend, I touched the blade tip to my belly button. The prick of the sharp steel made me harder.  I turned the blade so the sharper end was facing my chest.

"Fuck this life," I said aloud, and jammed the blade all the way into my stomach.

I cried out in pain and suddenly felt like my dick would spurt before I was ready.  The pain was nearly intolerable.  But I was so hard now, my dick ached to be released.  I quickly jacked off, spraying jizz all over my belly, and returned my attention to the blade in my body.

I steadied myself, breathing hard.  I began sawing the blade up towards my chest.  Each slice was excruciating. But I kept going.  I felt the sudden release of my bowels as they escaped my body and piled up at my feet.

I thought I might vomit, but my stomach was suddenly cut open by the knife.  Blood raced into my mouth, and I found myself coughing and spitting blood everywhere.  With my insides spread across the floor.

My mind raced, my heart beat like mad, and I felt myself on the verge of blacking out. I looked at the steaming pile of organs at my knees, and forced the knife one last time upwards.  I angled the blade so it would enter my heart.

The sudden and sharp pain of the blade knicking my heart was fleeting.  With blood now pouring from my mouth, my eyes rolled back in my head and the last conscious thing I remember was my head hitting the floor with a resounding THUD. That was it. I was dead.

They had decided together that Valentine's Day would be the end for Anthony.  He was dying of cancer, and wanted to go out on his own terms.  His partner, Danny, and their best friend, Logan, met in a run-down cabin in the woods.

The place was lit with candles, and Anthony appeared from the back room in nothing but a thong.  His cock strained against the tiny bit of cloth holding it in.  Danny looked at the beautiful man before him.  

"Since it's Valentine's Day, I want this to be special for you," Anthony said, stroking Danny's chiseled abs.  He slid his hand down Danny's shorts and grasped his hard dick.

"Just remember, I want it bloody.  Messy.  Painful, no matter what I say."

Tears ran down Danny's cheeks.  

"Don't cry, my love.  I'm going to a better place."

They embraced, their lips locked in a fierce kiss.  Logan appeared over Danny's shoulder, and Anthony backed up.

"I'm ready when you two are.  My cock is super ready too."

Danny knelt before Anthony and started kissing his rock hard stomach.  His outie belly button became Danny's target and he sucked on it.  Anthony's dick was harder than before.  With his face covered in his own saliva and sweat, Danny pulled down the thong and took as much of Anthony's cock as he could into his mouth.  Anthony's little head was covered in precum, which Danny graciously sucked up. 

Anthony could feel himself about to blow.  That's when Logan pulled out a long Bowie knife and jammed it deep into Anthony's belly button.  The young man lost all control of himself and as pain enveloped his belly, he shot his entire load into Danny's mouth.

The hot, salty cum filled Danny's mouth and he swallowed it all.  As the last spurts of jizz escaped Anthony's cock, he fell backwards, landing on the sofa.  His cock slid out of Danny's mouth and Danny jumped on him.  He grabbed the knife and began to saw Anthony's slender body open.  

Anthony screamed in agony as his body was split open.  Logan put his hands inside Anthony's belly and pulled it open.  Danny began wrenching handfuls of intestines and organs out of Anthony's body.  Suddenly, a fountain of blood erupted from the dying man's mouth and landed on his face and chest.  

It was dark red and smelled of copper.

His tormented screams turned to hacking and gagging as he continued to vomit blood.  

Suddenly, it was over.  Anthony quieted down and his breathing became ragged.  Danny and Logan stood over him, grabbed their hard dicks, and furiously beat off until their cum shot onto Anthony's bloody body.  His eyes watched with sight as their hot cum landed in his open belly. 

They watched his eyes roll back into his head and they heard his death rattle. Danny looked at Logan, and their eyes met.

Suddenly, Logan pulled out a gun and shot Danny in the chest.  The stunned man gasped and collapsed on top of the gutted corpse.

"Rest in peace, boys," he said as he walked outside Into the night.

We were resigned to our fates. Knowing we were both supposed to die, Erik and I made a deal. We would help each other commit suicide.

We left our bunks for the last time, our hearts racing. We stepped out onto the arena floor, and turned to face the Emperor.  We saluted him, then each other.

We gave the audience a good show for several minutes, lightly wounding each other's legs and arms.  That's when we put our plan into motion.  As we came together, we lowered our swords and plunged them into each other's navels. 

The pain that registered on his face was what I felt inside.  His sword passed through my body and out my back.  A white-hot blinding pain shot through me, and I felt my penis harden.  Everyone could see it.  As we stared at each other, I felt the tip of his penis touch mine.

"Pull it out, Mike," he said.  "I'm ready to cum one more time."

I yanked my sword free and he screamed.  He stumbled behind me and forced me to stay upright.  I felt his massive cock slide between my cheeks and into my asshole.  The pressure from his dick forced me to shoot my load before I was ready.

I grunted as he slid into me, and my cum spurted out of my dick.  I heard his groans as he forced his body onto the blade protruding from my back.  

Suddenly, he came inside my rectum and we collapsed.  My sword fell at my side.  The hot sun burned our skin, as did the scalding sand.

"Finish it," he whispered in my ear, licking it.  Everything hurts, but I grabbed my sword and turned the tip to my massive chest.

"Until we meet again," I said, pushing the tip against my skin. 

"Until we meet again," he repeated.

I pulled the blade hard and fast into my chest.  I cried out in agony as it sliced into my heart and I heard him scream as it pierced his hairless chest.  I felt blood surge into my mouth and spill down my chin and chest.

I looked at the Emperor, and he nodded with approval.  I looked at the spectators watching us. They were cheering.  I felt Erik's cum trickle out of my ass as we fell over, dying for the entertainment of others.  

I heard a loud roar and the sound of a gate opening.  I lifted my head in time to see a massive lion enter the arena and race towards us.  

I couldn't help but smile as his massive teeth sank into my belly and tear out a huge piece of flesh.  The lion feasted on my insides as I faded into death.  It was a good day to die.

This isnt a gut stab but its such a horny kill due to the guy's moans and groans i had to post it.
