Chapter 1
The first thing I became aware of when I woke was the light ocean breeze caressing my skin and the warm afternoon sun flooding in through the open window. The second thing I became aware of was that I felt really good: warm, pleasantly numb, utterly relaxed. I knew this was wrong somehow, that I ought to be feeling something radically different. Gradually, I remembered why, as the events of the patio, or what I could remember of them, came back to me. Still, the emotions I should have been feeling wouldn't come. I knew then that this was a terrible sign, but that too failed to rouse so much as a little worry.
I felt movement to my left, and the soft friction of someone's skin against mine. I wasn't alone. I was lying in a bed, with someone pressed up against me to both my left and right. Soft sighs, groans and moans reached my ears.
I turned. Lying to my right was Sean. He was on his back, and naked, of course, but he was placidly snoring away.
To my left, Logan lay on his back, also naked, but, unfortunately, very much awake. Dad was lying on his side to Logan's left. He had his tongue down Logan's throat, one hand exploring the hard planes of Logan's muscular chest and the pronounced bulge of his heavily distended stomach, as his tentacle cock pistoned slowly in and out of his pussy. A good foot of his cock was visible as it curved up from his groin, arched over and straight down into Logan. Their flawless skin glowed bronze in the soft afternoon light as they fucked.
The most disturbing part was that I didn't feel disgusted, horrified or even mildly unsettled, as some still lucid part of me knew I should have. All I felt instead was that warm, pleasant numbness, and, unfortunately, no small degree of arousal. The longer I watched, the more aroused I became. I was soon rock hard.
Dad's moaning gradually grew more intense, his stroking of Logan's belly more feverish, the pistoning motion of his cock quicker and quicker, until, finally, he gasped and let out a deep, guttural groan, as his cock plunged deep into Logan. The visible portion of it began to ripple as his ejaculate pulsed through it. That pushed Logan over the edge, and, with a series of high-pitched gasps, he came too.
It seemed to take Dad forever to finish pumping his load out into Logan, into his son, into my brother. When he finally did, he pulled his tongue out of Logan's throat and looked up. Noticing me watching, he smiled. "Hey there Timmy. You're awake. Great timing!" His cock abruptly jerked out of Logan's pussy, eliciting a gasp and moan from Logan. Undulating, it stretched in my direction, more than half of its fat shaft slick with Logan's juices, it's thick head still leaking and still connected to Logan's slit by two long, thick strands of milky white semen.
"Clean my cock, Timmy," Dad ordered. Something about his command seized me, compelled me to obey.
"Yes, Dad," I replied automatically, as I propped myself up on one elbow and swallowed as much of that writhing tentacle as I could. Dad gave a low groan of pleasure. The taste and scent of his cum, not to mention the feel of his cock in my mouth, or of the relatively small portion of its considerable length that I managed to swallow, immediately awakened all of my senses, as an erotic jolt shot through my body.
Instead of the panic and horror I knew I should have been feeling, I felt only pleasure and relief. What have they done to me, I wondered dimly as Dad's monster member writhed and wriggled in my mouth. It forced its way part way down my throat, nearly making me gag, before pulling back a little and letting me go at it. As I licked and sucked, Dad groaned again with pleasure and went back to deep throating Logan, who was looking up at him adoringly, and gently rubbing his still growing belly.
When Dad's cock suddenly jerked out of my mouth, I was more than disturbed to find that my only reaction was one of disappointment. "Well done, Timmy. Now clean out your brother's cunt."
"Yes, Dad." I obeyed without so much as a moment's hesitation, getting on my knees between Logan's legs and plunging my face into his still wet and swollen pussy, which elicited a long, appreciative moan.
The scent of Logan's slit, suffuse with the scent and taste of Dad's sperm, was incredible. It seemed to fill my body, to course through me, and made me stiffer than ever. Dad laughed and ruffled my hair as he got up. "Don't you dare cum, boy," he said. "I'll tell you when you can cum."
For some reason, that order alone sent another erotic jolt through my body. My face still buried deep in Logan's groin, "mmmm" was all I could manage by way of a reply.
Out of the corner of my eye, I watched Dad walk around the bed over to Sean, who was lying on his back, still asleep, belly bulging. Dad looked down at him for a moment, smiling fondly, as a father should smile at his son, except of course for the lusty gleam in his eye and that monstrous tentacle cock of his waving in eager anticipation. He got onto the bed, planted his knees to either side of Sean's legs, bent over and plunged his tongue into his cunt. The motion reminded me of a ravenous beast tearing into its prey.
Sean started stirring under Dad's vigorous ministrations and soon began to moan. Lifting his face from Sean's pussy, Dad took a long whiff, as he caressed Sean's rapidly swelling stomach with one hand. "Mmm, good boy," he said. " You're ready for Daddy."
With that, he stood upright on his knees, straddling Sean, hands on his hips. His cock hovered in front of him for a moment, undulating, as if appraising the muscular, young body lying on the bed before it. It also seemed to grow a little longer. Then, without warning, and without Dad moving at all from his upright position, it plunged straight down into Sean. Sean gasped with a mix of surprise and pleasure as Dad penetrated him and began to piston.
The sight of Dad jackhammering Sean with his tentacle cock disappeared from view as Logan put a hand on the back of my head and pushed my face deeper into him. His moaning intensified, and, with it, so did the scent and wetness of his folds. Somehow, I knew this meant that he was close to cumming again and my body responded automatically. I stretched my tongue as far into him as I could. He cried out and his whole vagina contracted as if to push me out, but, at the same time, he kept applying pressure on the back of my head with his hand, forcing me down into him.
I stretched out my tongue again and, this time, it made contact with something, something soft yet firm. Logan cried out again and I felt his groin muscles flex as he pushed the object out of him and forced it up into my mouth. He relaxed his grip on me, and I lifted my head out of his groin with the object still in my mouth. Opening wider, I let it drop down between his muscular thighs. It was, of course, a gleaming white, round, golf-ball sized egg.
Barely giving me a moment to catch my breath, he pushed me back down into him only to push another egg up into my mouth with another cry of ecstasy. He released my head, I dropped the egg between his thighs, and he pushed me back into his cunt to repeat the process. Logan climaxed again with every egg he pushed out, his belly slowly deflating as he spawned.
I wanted to be disgusted, to beg him to let me go, but the greater part of me, the one that was now in full control of my body, wanted anything but. Waves of near-orgasmic pleasure washed over me every time he pushed me back down into his cunt and forced another egg into my mouth. I desperately wanted to cum, but I couldn't climax, and I was sure I knew why: Dad had ordered me not to.
"Ah yeah, that's a good boy, Logan!" Dad exclaimed. "A very good boy! Master will be so pleased!" He was still straddling Sean, hands on his hips, pistoning in and out of Sean's pussy, but the slight strain in his voice told me that his own orgasm was building.
"Thanks Dad," Logan said, smiling proudly as I finally added the last of his eggs to the pile between his thighs. Without giving me a second look, Logan then got up, collected them and dumped them into a large bowl on the dresser. The bowl already contained quite a few eggs, doubtless those I had watched them lay in the bathroom.
"Ahhh yeah! Here it comes boy! Here it comes!" Dad roared, throwing his head back in ecstasy and plunging his tentacle cock deep into Sean. The still visible portion of it immediately began to ripple and pulse, as he started pumping out another monster load.
As Dad filled him with his sperm, Sean came with a gasp and cry of his own -- "Ah Dad! Ah god yeah! Fill me up! Fucking fill me up!" With every load Dad pumped out into his son, he seemed to be doing just that. Sean's belly grew larger and larger beneath my very eyes, until he looked several months pregnant. I watched, transfixed, as their orgasms reached their zenith and then slowly died down.
Again, it took Dad well over two minutes to finish ejaculating. When he finally finished, his cock jerked out of Sean as abruptly as it had out of Logan, and, slick from being inside Sean, sperm still leaking from its engorged head, it undulated over to me. Dad looked at me and smiled. This time, he didn't have to say a word. I swallowed it immediately, pleasure and relief washing over me in equal measure. Its taste and scent made my own cock start leaking pre-cum like a faucet.
"Lucky Timmy," Sean mumbled. Somewhere behind me, Logan chuckled.
I felt the same disappointment as I had earlier when Dad's cock abruptly pulled out of my mouth. The disappointment was forgotten in the next moment when Dad ordered me to clean Sean's slit, and the scent and taste of Sean's juices and Dad's sperm filled my nose and mouth. Dad and Logan left us going at it as they headed out.
I soon had Sean moaning and groaning, and it wasn't long before my tongue felt the first of his eggs begin to push out and up into my waiting mouth. As Sean climaxed again and again, he spawned a good half dozen eggs, which I plucked out of his folds one by one and deposited between his thighs. When he was finally done, I helped him gather them up and add them to the ones that I had watched him spawn in the bathroom.
"Wooh! Nicely done little bro!" Sean said, hooking one arm around my neck in a kind of bro-ish frat-boy hug, and steering me out of the room. His stomach was almost back to normal. "I'm so glad you're going to be our cow and sex slave. Insemination and spawning is going to be a lot more fun with you around!"
