Once again, I woke up with a screeching headache. I was starting to get a little tired of passing out. My body didn’t ache this time. In fact, it started to shiver from the cold surface that was pressed against it. It felt like hard marble. As I slowly rose to my feet, I realised where I was. A large wall of glass surrounded me. I was inside the dome!
The sky had turned black, as the moon looked down on us like a lunar spotlight. How long was I out? I could hear pounding against the glass. The entire family was on the other side, all donning loincloths that barely concealed their raging boners. They were either having sex, jerking off, or both, as they watched me from the other side of the glass. Their wrists and ankles were decorated with lion’s fur. I could see their thick, wet chest hair shine in the moonlight. I felt my cock twitch, as I looked down to see I was also wearing a loincloth, which only covered some of my recently-grown package.
As I tried to find a way to escape, I couldn’t help but admire the dome I was trapped in. The exterior was adorned with incredibly well-crafted statues and rows of metal, which ran along the floor. The same symbol from Joe’s old tattoo were scattered along the marble, as they formed a circle around two men with lion’s manes in the centre.
A large circle of red glass hung above me, angled towards the moon. I noticed Joe lying down on the opposite side of the dome. He groaned as he regained consciousness, leaning on the glass as he lifted his hulking frame. He now stood a few inches taller than me, at around 6’10”. His massive cock tented his loincloth, lifting up the fabric to reveal his balls, which were already on the brink of exploding. I tried to run to him, however a thin sheet of glass separated us into the different halves of the dome. I pounded my fist, hoping to break it, but to no avail. Joe could hear my attempts to get to him, and as he saw he, he ran to meet me at the glass wall. I couldn’t hear him as he spoke, as his voice was too muffled to understand it. He looked at my mostly naked frame, licking his lips as his cock throbbed. Seeing him get so turned on caused my dick to slowly harden. Joe instinctively began jerking off, as his brothers watched on with lustful eyes.
However, before he could finish, one rectangular hole in the glass formed on each of our sides, leading onto the lawn. We could hear the rest of the family. Just above the cacophony of whistles and loud cheers, egging us on, I turned to see Aku stand on a platform above them, holding a megaphone. Whilst his loincloth was made from the same, brown material as ours, the ceremonial lion’s mane around his head was so eye-catching. I couldn’t take my eyes off it. The headdress was huge, and it casted a shadow over some of the boys. Dan was lying on the ground next to him, completely worn out from their intense orgy earlier. He looked on at Joe with regret. Joe, however, was too busy blowing a load on the dome walls, causing his brothers to yell eagerly, as they showed off their brawny frames, which only provoked our sex drives to kick into overtime. Jim bounced his pecs as he smiled at me, my horny mind growing even hornier. I tried to yell towards Joe through the hole.
“Joe! Are you alright?!”
“I….I can’t stop. It feels too good! Ohhh-“
He continued jerking off, using his load from before as lube for his hands. Before I could say anything else to him, Aku places the megaphone in front of his face. When he spoke, the man’s booming voice through the megaphone nearly deafened us. I was surprised the sheer volume didn’t shatter the glass.
“My sons, witness our glorious bloodline flow through your brothers’ veins. At precisely midnight tonight, when Joe turns 18 years of age, he will transform into a man. See how the Spirit of the Lion has already begun to claw its way out of him.”
Most of the boys imitated a lion, roaring with anticipation as they flexed their muscle-bound bodies. Joe grunted deeply as he grew a few inches taller. He was too busy grinding his cock against the glass to notice. I felt my body heat up. It was the Beast. I needed to fight it.
“The nature of their transformations are different tonight, however. May I present to you, our new Patriarchs!”
The boys cheered boisterously as Joe came again. As his load dripped down his shaft, and onto his balls, they swelled slightly. A sudden wave of testosterone flooded the boy’s body, causing another layer of hair to sprout on his face and torso. Despite cumming a second time, the boy was still tirelessly jerking off, much to the rest of the family’s amusement.
“We have served our tribe as Patriarchs long enough. These two boys will be the new heads of the family, and so I expect you all to treat them as such. Of course, this will mean they will become warriors, far greater than Dan or myself. Let us bathe in their glory, as they become the beasts they are destined to be!”
He dropped the megaphone and, picking Dan up from the floor, began gently making out with his partner. I looked up; the moon was almost perfectly in line with the circle of glass. I knew there wasn’t much time left. I could hear Joe’s voice cry out between his moans.
“Ohhh fuck! What’s-AHH! WHAT’S HAPPENING TO ME?!! OHHH!”
Suddenly, a luminous ray of moonlight shone onto Joe. We both shared one last fearful look, until he suddenly convulsed, falling to the floor. As he writhed about, I notice his back widen immensely, broadening his shoulders. His bare ass that stuck into the air ballooned in size, as it snapped the waistband of his loincloth off of him. His thighs thickened to the size of tree trunks, as they quickly darkened with multiple layers of hair. His grunts and yelps dropped an entire octave, until it sounded like the noises of a large animal. I noticed he wasn’t in pain anymore, and had moved onto aggressively grinding his cock against the marble floor. I could see his manhood extend to 2ft. Then 3ft. Then 4ft. All in the space of less than a minute. Once it reached his head, he quickly shot up to his feet, and shoved his face into his cock, licking as much of the obscene amounts of precum that leaked from it as he could. I found myself staring at his balls which had grown way past the size of bowling balls. He could barely fit one in his hand and, when his body grew taller, even more muscle was packed onto him. All he could care about at that time was jerking off. Everything else left his mind. It was as if he had forgotten who he was. As he was about to cum a third time in the dome, he stared at me. Only this time, his eyes were blinded by his insatiable lust, and uncontrollable, bestial desires. He needed to fuck someone. He wanted to fuck me.
He was now a 12ft hulk of muscle, hair, and sweat. His cock still throbbing, with large veins bulging from his length. His low grunts didn’t sound like him. They sounded like the grunts of a beast. His thick beard was covered in his seed, as it dropped slowly down his neck. His ripped chest moved with his breaths, and his biceps flexed when he gripped his giant member. Aku laughed in the megaphone, as Joe’s brothers stood and stared in amazement at their grown sibling.
“Bask in the glory my son. For it is that glory you will share. Now!”
Jim grabbed a large lever sticking out from the side of the dome and, with all his strength, pulled it down. As the lever fell, the dome rumbled, and the sheet of glass between me and Joe opened like one giant sliding door. When it opened, the potent stench of Joe’s new form forced its way into my nose. I could feel the boy’s body heat even from where I was standing. However, before I could take it all in, Joe was already lunging towards me, his giant pecs bouncing with each step. Once again, I froze, both from fear and arousal. I could feel my stiff cock smack the boy’s thigh as he picked me up with his manly hands. His eyes shined under the moonlight. Neither of us moved. All we could do was gaze upon our naked bodies with anticipation. As we shared our intense exchange, Aku began to grow impatient.
“It would seem our new Fathers are in need of support. Jim, Open it all the way.”
“Yes Father!”
Jim eagerly pushed the lever down even further, as the glass walls of the dome collapsed into the floor. The brothers, without any hesitation or nervousness, sprinted into the dome, surrounding me and Joe. They worshipped their brother’s fully-grown frame, rapidly massaging it with their hands. One boy grabbed Joe’s ass and squeezed, causing the giant to moan loudly. That must’ve snapped him out of his trance, as he forcefully hoisted me onto his cock. It was way too big to fit, as I could feel his precum flow like a river between my cheeks. The rest of the family quickly stepped back, before turning to each other with their rock-hard manhoods. It wasn’t long until another orgy has formed beside us. Aku and Dan stayed on the platform, jerking each other off. I don’t think Joe realised his cock was too big. I don’t think he cared, and as I felt him turn me around, and shove his member deep into my ass, I yelped. The feeling of his shaft stretch me was both incredibly painful and pleasurable. I could feel his thick fingers wrap around my waist, as he thrusted. I cried out, lost in the sensation of his cock slowly filling me. The pain in my chest returned as I tried to suppress the Beast once more. Jim stood just in front of me, jacking off as he watched Joe slide another foot of his meat deeper into my ass. He playfully bounced his pecs at me again, before reaching for my shoulders. He rubbed them gently, and as I looked up at him I could see a huge smile on his face.
“Like it or not, you’re a Patriarch now. There’s no point in fighting it Jamie. Just relax!”
At this point, his advice was the only thing I could follow. Joe loomed above me, his bulging stomach rubbed against my back. The pain in my stomach, it was just too much to bear. Jim could see I was still resisting, as he drew his face closer.
“Let me help…”
Suddenly, I felt his lips on mine, as we made out. I finally caved to the beast, embracing Jim’s kiss. My body began to grow incredibly hot. I started sweating profusely. Jim, seeing my body drenched in sweat, laughed as he continued pumping his cock.
“Welcome to the tribe Father.”
Just as he said that, I felt Joe push more of his cock into me, catalysing an overwhelming wave of pleasure. I felt a shockwave travel across my entire body, starting at my ass, which suddenly expanded outwards, becoming more plump and round. My back stretched out, as I felt my shoulder blades shift even further apart. Looking down, I could barely see the floor, as my two huge pecs had swelled considerably. They were quickly bathing in a layer of thick, sweaty chest hair that was growing from my chest. As my neck grew bigger, my voice became even deeper. I continued to grow, until I was much taller than Jim, who watched me grow as he jerked off. Joe’s cock thrusting into me gradually felt less painful, as I soon realised I had grown as big as him. My balls were touching the floor, as they dangled from the base of my now 5ft cock. I couldn’t believe what had happened to me. I was now one of the giants. The wave of pleasure then traveled into my brain, as I felt my mind begin to calm down. My thoughts of who I was, and my family back home, they were all slowly fading away. All I could think about was where I was in that very moment, and what I needed to do.
My best friend was fucking me with all his might. I knew our thoughts were the same. He needed to fuck me, just like I needed to fuck something too. I needed to breed. The only person that was in my field of vision was Jim, who gazed upon my body in awe. As I picked him up I could barely speak, my mind was filled with my bestial urges. I put my mouth by his ear, and whispered in my new low, growling voice.
“I’m gonna tear you apart.”
“Do it, Father.”
He didn’t resist. Instead, he spread his ass wide for my cock, as I violently thrusted it deep into him. He moaned loudly, almost unable to contain the overwhelming pleasure. The sudden realisation of being sandwiched between these two beautiful men only turned me on more. I could feel my ass fill with Joe’s seed. His thrusts quickened, as I felt his hot breath spread across my back. I knew he was close, and so was I. Therefore, as I pulled Jim closer to me until I was almost balls-deep in the boy, I stepped backwards, pushing my ass further down Joe’s shaft. Our three collective moans filled the entire lawn, the ground rumbling from our deep, thunderous voices. That was enough for all of us to cum.
All of his brothers, even his Fathers, were hypnotised by the beast that stood before them. They all stared in awe as the boy’s bulbous asscheeks clenched. Joe closed his eyes, and tilted his thick neck back, before letting out an animalistic roar. His masculine body, his ceaseless libido, it all culminated into this one sound that sent a seismic wave across the lawn. As the boys heard it, they all let out a deep moan as they came, simultaneously emptying their balls onto each other. Aku and Dan also came, their raging hardons shooting a thick stream of their seed high into the air. It was as if his roar made the family cum.
As he finally emptied his balls into me, all I could feel was his loads spread across my entire body. As I came, I gripped Jim’s manhood and pumped it, causing him to blow his load too. Like a giant, meaty water pump, I filled Jim with my seed. Our loads were seemingly endless, and as Jim stopped, Joe and I couldn’t. Our balls were so full, we had no idea how long they would take to empty. Our sex-crazed minds only caused them to fill with even more of our hot, fresh semen. Jim began to panic. My cum was filling him up, with no sign of slowing down. He tried to jump off my cock. However, noticing his escape, I grabbed him and held him close to my chest, pressing his face between my pecs. Jim moaned as an intense orgasm pierced his body with every load I shot into him. His stomach actually began to grow outwards, as the sheer volumes of my seed was almost overflowing from the boy. He was too lost in the pleasure to care, as he came again, a thick white stream splashing all over the dome floor.
I wasn’t sure how long we were like that. When I eventually shot my last load into Jim, he collapsed onto the floor. I fell onto Joe as he slid his now-flaccid meat out of my ass. He caught me in his arms, as we both shared another look. Our eyes were the same, but everything was so different. I felt my mind grow back to normal, as my memories and thoughts returned. Joe looked worried.
“Are you Okay?”
“I’m fine. I’m more than fine, I feel amazing.”
“I wasn’t too hard on you?”
“No. You….you were great.”
“I love you.”
“I love you too.”
We both smiled.
“Wanna hug?”
“Fuck off.”
We both roared with laughter as we wrapped our arms around each other tightly. Our embrace filled me with happiness. I knew from then on I wanted to spend the rest of my life with him. He thought the same, as neither one of us wanted to break from that hug. However, Aku’s rigorous clapping broke it. He walked over the pile of horny boys and cum, until he was standing right in front of us. It felt so strange to be taller than him.
“Well done my boys, I am so proud of how far both of you have come. Please, take this, you are in charge now.”
He took off his headdress, and handed it to me. The smile never left his face. Dan tried to approach us, only to slip and fall onto Pat and Steve, who were too busy making out to notice their Father pressed between them. Aku laughed.
“Now, if you excuse me, I believe my partner and I are ready to enjoy a well-deserved retirement.”
He pulled Dan out from underneath his two sons and, carrying him like a groom carries a bride, they made their way back into the mansion. The rest of the boys gathered round, their bodies dripping with sweat and cum. Their cocks were already starting to grow erect again, as I saw one playfully slap another boy’s ass. They all looked at us, waiting. Jim stood behind them, feeling incredibly bloated.
“Well, what do we do now Fathers?”
Joe looked at me, unsure of what to say. All I did was smile. I wanted to embrace this new life with open arms. I stood there, gazing at the large tree in the distance, until I thought;
“I would kill for some breakfast right now.”
