Then I saw his erection, and how big it really was, how veined, how enormous, and I nearly choked. Engorged with blood, viscously red, veined completely around the circumference, it had grown. Easily a foot long, it protruded from the black sheath and swayed with absolute menace. I coughed, stared at it open-mouthed while my heart tattooed beats through my chest

"My God," I whispered. I gulped. The sound was an audible clack. "You were gonna put that up me?"

Koko nodded, tongue lolling out.

"No way."

His erection swayed back and forth, bouncing, dripped a thick clear drop of semen onto the floor. My eyes could not, would not, believe the sight.

I rubbed the sides of my jaw.

"Ha-God." I shook like a California earthquake.

The tip was not pointed like a human penis, but a thick blunt end having a large hole offset from the center, It was bordered one side by a crest. There was no discernible transition from head to the shaft, no glans at all. Just a huge swollen tapering club. I started when a huge dollop of semen splattered obscenely on the floor.

"You were gonna put that in me?" I repeated

Thoroughly rattled, I drew up my legs. I had forgotten the ache. I wanted to touch Koko, feel the thickness for myself, find out if the skin was as hot and as angry as it looked. And despite my revulsion, the desire was strong. I slid off the bed and squatted beside him on the floor, not believing what I intended to do.

"Don't do this, Michael," I said. I pleaded. "Please?"

I placed a hand on his back and reached between Koko's legs and carefully took his penis in my other hand hand. It was as hot and angry and dangerous as it looked. It thud with the beat of his heart.

"Oh my God."

Koko sat unmoving, content to let me hold it. Then he did two things. He arched his pelvis forward and he licked my mouth. I broke out laughing, stunned.

"Jesus, Koko." I wiped slobber from my mouth.

"That tongue has been in unmentionable places." He butted my shoulder, and so, gently squeezing the shaft, I stroked him a few times. He was incredibly taut, much hard than my own penis. (Or that of my friend David, who also I had stroked.) My hand slid up the thick flesh with ease, collecting lubricant between the fingers. Whatever it was, the stuff worked great.

I continued to stroke, becoming used to the act, and my hand slid farther and farther up. Soon I stroked the entire thing. Koko spread his legs and again I laughed.

"You're no dummy."

He licked my face.

My own penis was amazingly hard. Rising tautly like a flagpole, I don't need to tell you how much it ached. The more aroused I became, the more I suffered. I had to work it

"This puts me in the lowest class of human shit," I said. "I hope you appreciate that."

The muscles in his back worked and Koko began to shudder. If possible his penis grew more taut. My strokes ran the entire length, and I don't know who was more excited, Koko or me. Lubricant had worked itself onto the back of my hand and over my wrist and dripped from between my fingers. I too was making a mess of the Mrs.A's floor.

I said: "I guess you--" and got no further.

"Whoa, boy!" I yelled, dodging backward. "What are you doing?"

Koko butted me with his head. Then again harder. Then he arched his back and stood up and put his paws on my chest and shoulders and thrust forward with his pelvis catching me in the sternum. I went over.

"Hey! Take it easy. You already tried to mount me once. I'm not ready for that."

Did that mean I soon might?.

What exactly, did I really want?

His penis was circled by massive knot, blood red and three inches around. It protruded from the base like a huge growth. I stared, amazed. If that ever got inside you, my brain announced, it would tear you apart. Or you'd walk like Charlie Chaplin.

"Don't worry," I muttered. "It won't."

Women (and also some men) enjoy sex with dogs. I've seen as much on the Internet. But the idea of Koko's penis in my ass or my mouth seemed ludicrous. First, it wouldn't fit. My rectum was eight inches deep and I might handle the length of a normal sized dildo (or penis for that matter), but that was all. Koko was nearly twice that long. I might as well fuck a horse. And by mouth? Not even Julia Roberts with her huge kisser could do that. No, the fantasy was terribly strong, but it was just a fantasy. Which hurt because the more I stroked him, the worse the desire became.

Squatting was difficult and I changed position. I stretched out but this was only marginally better, and my forearm tired rapidly. I tried supporting myself on one elbow, but the carpet ate my skin, and the angle had my shoulder aching something fierce. Finally I moved into a sitting position, and this was the worst position of all.

Frustrated, I said: "You better enjoy this, Koko. Because it's killing me."

He licked my face.

Deciding it was stupid, I reached behind and sought out his testicles. They were enormous, lemon-size, one larger than the other like those of a man. The tubes I felt coming off them were thick as a pencil. This is a lot of plumbing, I thought. His orgasms reach the megaton range.

The lubricant did a marvelous job, but smelled just awful. (Imagine a huge Vienna sausage slicked in slimy gelatin.) Giving off an odor of musk, it made me slightly nauseous. Koko, antsy and starting to move about, began to lick himself, and then me. I didn't complain.

Soon he growled and shifted on his haunches, making it evident he needed more. Trying to decide what next, I hesitated a moment too long--Koko decided for me. Rearing, he caught me by surprise and knocked me onto my back. His forepaws came down on my shoulders.

"Whoa!" I tried to push him away. "What are you doing?" He lost his footing, slipped off, and gouged long grooves into both shoulders. I howled loudly.

"Koko! Get off!"

Then the impossible happened. He lost his footing completely and came down in my lap, crushingly hard on both testicles. They were mashed to the floor. The world exploded and the heavens caved in and the inside of my eyelids burst in a cascade of flames. The air turned to molasses in my lungs.

This time I passed out.

An interval passed--how long I'm not sure, it could have been a week--and then Koko woke me with his nose.

"No. Please."

Koko paid no attention.

I was in a fetal position, anus exposed, and the persistent Koko found it too ready a target. He lapped and I had no choice but to let him. After some minutes, however, I turned onto my stomach and crossed my ankles, momentarily thwarting him. He backed away. Then he sat down. He watched with disapproval.

"Fuck you," I croaked. "Enough."

He maintained watch another ten minutes, penis huge and bouncing, occasionally dripping semen. I turned onto my back, again spread my legs and checked for damage. Not squashed flat as I feared, though still incredibly bruised. It was like touching a deep, open wound.

I asked: "What did I do to deserve this? All I wanted was to beat off on Mrs.A's bed, maybe fuck myself in the ass. Instead I get this." I laughed at the ceiling. "I never asked for sex with a dog. Never! Please stop torturing me."

Koko, nothing if not persistent, circled and sniffed. I shoved him away--or tried to.

"So help me, Koko, leave me alone or I'll bite off your balls."

He continued to circle, looking for my penis, anything good to lick. I let him have nothing.

"Go to hell!"

Again I turned over and crossed my ankles. Tighter this time. His tongue sought out it's target anyway, and straddling me, he worked my compressed cheeks until fighting him was pointless. I uncrossed my ankles.

"You son-of-a-bitch."

With the persistence of a honey bee repairing its nest, Koko worked deeper into my crack. My breathing increased, so too my heart beat. How could anything feel so good? I shifted position on the floor; my legs opened. I moaned.

"Jesus. Mnnahh!" I gasped when he found my balls.

"Easy! Easy! Neuhh!"

To this day I don't remember deciding. I suspect Koko decided for me. My tail rose and both hands spread my cheeks and very shortly, I was squirming uncontrollably and coming higher up. I made noises both humiliating and provocative.

"Oh, no! Oh, no-no-no!"

My threshold of pain was sky high--or I was numb to it--and my testicles bounced like rubber balls on a wooden paddle. My hard-as-an-iron-spike erection slapped my belly and the harder Koko licked, the higher my ass went. Soon it could go no higher. Both shoulders and my chin were burned (Let a boy explain that to his mother) and somehow I had crab-walked into the bed. My head was against the frame. My balls were demolished. I was too aroused to care. I wanted Koko so badly I whispered and pleaded and begged.

This time I would not stop.

I spread my cheeks, making my anus a bullseye. Koko took it all. For minutes this went on, until coherent thought was lost and I was ready, willing and able to fuck. Koko had other intentions. Suddenly he was at my face, licking furiously and I was so startled I yelped.

"What?"

He butted me.

"What are you doing?" I could not believe it. The way he worked my tail I couldn't imagine him wanting anything else. Yet he was soaking my face with slobber and I got on all fours and pushed him away. I sat back.

"I thought you wanted to fuck me."

His penis bounced, thumping the floor. He licked it.

"No way," I said. "You can forget that! Right now!"

He continued to lick my face.

"Either you fuck me," I said, feeling completely ridiculous. "Or it's nothing. I'm not giving you head."

He turned and sidled against me, raising his hind leg and jutting his penis against my side.

"No!" I broke out laughing. "Forget it!"

He reared and landed both paws on my shoulders and over I went again.

"God dammit! Koko! No!"

He stood on my chest, looking up and back, then moved forward. His penis came right over my face, dangerously close. It thumped with blood.

"Koko--" I squirmed, dodging the tip. "You're not putting that in my--"

Then he slammed downward and I screamed.

"Get off of me!"

I had opened my mouth at the wrong instant. Suddenly it was there, pushing past my lips and I convulsed in panic, smacking my head on the floor. Sparks flew. I tried to push away, but his penis pushed in deeper, and then my mouth was jammed and the crested tip pressed into my throat.

I stopped struggling.

Every movement, his or mine, threatened to choke me.

"Mmmnnmmmnnnnffffffff! Mnnnnhhmmmnnnffff."

I was sucking a dog's cock.

I gripped his hind legs but was afraid to move while he jack-stepped on my shoulders. He tried to get footing. What he accomplished was to tear up my skin. I held him tighter and pushed back but he was like a bronze statue. The slimy lubricant was violently bitter and made me retch. It ran down my cheeks. It coated my lips and my chin. The baseball-sized knot was eight inches from my nose, and I looked at it in cross-eyed horror. Warm, salty fluid filled my mouth. It was semen.

"Mmmnnmmmnnnnffffffff!"

Seconds passed and semen filled my mouth. It had nowhere left to go: I refused to swallow. It erupted out my lips, blew into my nose, and I gagged. Then I swallowed. And swallowed again. Then a whole lot more.

"Mmmnnmmmnnnnffffffff!"

The flow increase until it was a river of flowing gook, a veritable cascade. If something didn't change, and change soon, I'd have a stomach full of sperm.

Something did change.

Koko lunged forward and down my throat and I was deep-sucking three inches of dog. He began to fuck me.

"Mmmnnmmmnnnnffffffff!"

My jaw stretched until muscle's creaked and joints popped, and I could breathe only when he pulled out. A rhythm set up, a horrible cadence, where his penis came down and my mouth went up, my throat distending to let him in. Mindless, I began to suck.

"Umnniiinniiimmmm."

His penis went deeper.

"Mmmnnnniinmmdddfff."

My mouth could open no wider, but I used what muscles remained to coax movement out of my tongue. I extended as he came in, sucked as he went out.

"Gllluuummmfffffvvvv."

Swallowing as practical, I closed my eyes and concentrated on making this work. It did.

"Mmmnnnniinm."

Soon the rhythm became a tango and Koko and I danced. I sucked and he panted. He blocked my throat and I chose not to breath. Every ten strokes or I did breath. I did not care. This was nirvana. This was joy. My five and a half inches of erection wobbled and swung and cut the air like a conductor's baton, its movement arousing me more. I clenched my scrotum, relished the testicular pain.

Every sense was a cacophony of sound, of pleasure. I watched the cardinal knot come closer, five inches from my lips--then four, then three. I began to masturbate. How much could I take? Eight inches? Ten? A foot?

I began to masturbate furiously.

The knot came closer; jagged veins standing out across the flesh, literally thumping with blood. It could not fit in my mouth. Nothing that size could fit in my mouth. But on one especially brutal plunge, Koko brought it against my lips and I could no longer see it.

Guiness will never record it, but a record had just been set. He was fully within my mouth.

I could not breath at all.

For a moment no one moved, then Koko lunged again and the knot wedged in my teeth and my eyes popped right out of my face.

I tried to scream. No sound came out.

Finding himself immobilized, Koko stopped lunging and began to whine and danced around. He skittered on my chest and shoulders, claws digging the skin. His penis thudded deeply in my throat.

I saw double. My lungs convulsed. Strangulation threatened to send me down a black hole.

If he came now, sperm would explode right into my stomach.

Reaching up, I planted both hands against his underside and with the last of my strength, pushed mightily upward. Koko's hindquarter's lifted from the floor and though he yelped and made noises like a maddened dog, his cock would not budge.

The knot had swollen larger.

With desperation borne of terror, I forced open my jaw and shoved again. Koko planted a hind paw in the center of my chest and pushed off, and the knot popped free. Pain exploded as my head smacked down on the floor and my throat spasmed. Free of its obstruction, it sucked down air and I began to gag and retch and do whooping coughs.

Someone had rammed a flamethrower down my throat and pulled the trigger.

"Stop it!"

Koko licked my face, butted me with his snout. I could not escape his tongue.

"Leave me alone."

I was nauseous and dizzy and covered with slime. My throat ached. Everything ached.

I pushed away his snout.

"Go away."

I sat up, and I swear my stomach swooshed. I grimaced.

How much had I swallowed? A quart? A gallon?

Koko licked my hand. Koko licked my penis. Koko licked my swollen balls.

I lay back down, raised and opened my legs, stared at the ceiling.

"I am not in control of my senses."

But Koko was in control of me.

I turned on my stomach and went up my knees, spread my cheeks. He attacked with feverish intensity. His tongue was remorseless, his snout a live dildo. My anus quaked and I quaked inside. I prayed to be fucked, to be fucked right now, to be fucked long and hard and deep.

Very long and hard and deep.

I wanted a gallon of sperm in my rectum. I wanted his twelve inches and four inches in my ass. I wanted my anus stretched like a rubber band. I wanted pain!

"Please, Koko," I whimpered. "Mount me!" Koko mounted.

Something wet and sticky and hot smacked my anus. I whimpered again.

"Please!"

Claws raked my calves and gouged my back and I didn't care. Koko wrapped his front legs around my middle, clambered onto my back, and the same hot, wet and sticky thing planted on my anus. I reached back and found him ready at my door and held the tip in place and thrust my anus back up against it.

"Come on! Come on! Kokooo!"

Nothing happened again. Just as I thought nothing would ever happen, he penetrated and I grit my teeth, sucked down breath. I shuddered everywhere at once.

"Ohmygod-ohmygod-ohmygod!"

My chest pounded the floor. His erection pounded my ass. Fever like poison pounded my brain.

My anus stretched like a widening mouth, and then the tip was in and I began to moan.

"Owwww! Ohh-noo!

He was three inches thick at least, and as the thickest part entered, my ass began to spasm. I grabbed his legs, hung on.

"Oh God!" Jesus! "Oh God!"

I felt pain. I felt REAL PAIN! I felt the rim where I gripped his shaft and felt no anus at all, just a sucked-in depression. I guessed he was halfway there.

"Koko! Oh God, Koko! This hurts!"

A telephone pole was inside, not a penis, a monster from a nightmare. I shook my tail. I wagged it. I started to cry.

"Oh-no! Oh-no! Ohhhhh-Goooooddd!" I wailed. "It hurrrrtttssss!"

The pain stopped my breath and almost my heart.

I was fucking deep-fucking a dog.

Koko got going then, up and down, in and out, and though clumsy and frenzied, he had me pleading for more.

Every inch was paid in pain.

Convinced I'd snap like a rubber band, I released his legs and clasped my buttocks again, parted them like the Red Sea. I stared at the wall, at the cool white paint, at the smudge two feet off the floor. At the nail pop six inches from the door. I asked what a penis the size of a beer bottle was doing in my ass. I asked what a boy my age would do if caught with a penis the size of a beer bottle in his ass. I stared at the box of Mrs.A's pictures on the corner of the dresser and wished I never found them. I stared at the wall and heard Christmas carols.

Koko halted and shifted his weight, climbed higher. His claws dug my skin before he gained purchase and God, I thought, how am I going to explain this? Then he started humping, and six inches, eight inches went in and out with each plunge.

I was being deep-fucked by a dog.

I gasped.

I mewed.

I whined.

I was the churn and Koko churned my butter.

I lifted my tail higher, high as I could get, and Koko knotted out against my anus. The ridge of bone which normally stopped my dildo's didn't stop Koko because he was flexible and pliant and just didn't know bounds. He went in my colon.

The pain exceeded enormous. It passed cataclysmic and became catastrophic. Every thrust made my rectum scream, and threatened to tear it loose from my anus. I wanted the knot. Jesus Christ and God Almighty I wanted the knot!

"More, Koko! More!" I begged. "Please more!"

I wanted the knot.

I wanted the knot!

I WANTED THE KNOT!

Koko stayed on me, riding, my ass bucking him up and down. The knot worked further and further inside, and on one especially deep plunge, it went in.

Whoooosssshhhhh!

Air went into my lungs, then out.

"Ohhhhh-gooooooddddd!"

The knot was trapped and Koko couldn't move. Rather he couldn't withdraw. He moved plenty.

I screamed and then screamed again, dragged covers off the King size bed and chomp them like a shark. I bit my tongue.

If you can imagine giving birth to a watermelon, that is how it felt.

I screamed a third time and a huge pressure wave blew into my bowels and Koko was coming. He howled in triumph, wrapped his legs around my waist and locked to me like a straight-jacket. I felt every inch and it seemed like a mile and it was all exploding at once. Then the whole room exploded.

"Nooooooo!"

I started to come.

He rode me through the first wave and into the second, then was mad-fucking me again, making me howl. Convulsion's wracked my spine and sperm flooded my bowels and a tremendous orgasm powered us both. Liquid the temperature of molten lead spurt into my ass, out of my ass, spattering on the floor and Koko. And all over me. And still he came.

"KOKOOOOO!"

Spurt after spurt after spurt blew in!

"KOKOOOOO!"

But nothing goes on forever.

Eventually Koko slowed, then slowed more, then stopped entirely. He let go of my middle and with him inside, I collapsed.

Time passed.

"No. Please God, tell me I didn't." My anus belched and a quake jolted my rectum. Nothing but red carpet in my eyes. Then that faded away too and then I was gone.

I awoke on my stomach, empty. Koko lay beside me, licking his penis, softly panting. Every muscle ached and a throb in my bowels told me I would ache for a week. It lasted two.

I drifted off again.

This time it was six o'clock.

The parents were home, no doubt wondering where I was; I struggled to move, stopped that foolishness when every muscle screamed in protest. My rectum exploded a loud belch. Poison gas wafted and Koko rose up, moved to the doorway.

I began to laugh.

His tongue lolled, and for a time he stood there, undecided, looking down the hall. Then he came back.

He licked me.

I let him.

Two minutes later his erection was huge and so was mine, and when he butted me on the rump, the good bitch I am, I obediently raised my ass and was mounted.

I found this hilarious and began to laugh.

I was still laughing five minutes later when the front door opened and mother called and I didn't hear. Two minutes later when the bedroom door opened and I did hear it this time, and didn't care, I laughed even more.
