PART 4
Chapter 1
On waking, I had sort of expected to find Dad hard at work with that tentacle of his deep inside Sean or Logan. Instead, I found myself alone, in Dad's bed but blessedly alone. I was pretty sure I was still naked, but I was mostly covered by a thin bed sheet. For a brief moment, I wondered whether I might have dreamt it all, whether it had all just been a terrible nightmare. That vain hope was dashed when Sean walked into the bedroom naked, a pussy between his muscular thighs slightly swollen with the beginnings of arousal, and his belly distended. He went straight to the closet, took what remained of the clothes inside from their hangers and stuffed them into an open suitcase on the floor.
"Hey bro! Finally awake!" he exclaimed when he noticed that my eyes were open. "Good timing. Dad says you need your sleep until your done changing, but we're almost ready to go. We were about to come wake you up." He was smiling stupidly again in that way that made him look as retarded as he had probably become.
"Go? Go where?" I asked, or tried to. My speech was heavily slurred, my tongue oddly large and heavy in my mouth. I put it down to being groggy and still kind of exhausted from the events of the last few days.
"Home of course," Sean said, as if the question had been completely redundant. "It's morning, and our plane leaves in a few hours." That distant part of me, the one that remained clear-headed, was now more distant than ever, but it was still there, and, on hearing Sean's words, it seemed to revive a bit, abruptly filling with a cautious measure of optimism. Home seemed synonymous with a possibility, however remote, of escape.
Sean turned back to the suitcase and bent over to zip it up, giving me a perfect view of his muscular backside and puckered asshole. He groaned as he straightened, clutching his growing belly, obviously pregnant with eggs, and gave an incongruous belch before dragging the suitcase out into the hall. Why was his belly so large and his pussy swollen like that, I wondered dimly. Surely he had spawned this morning. It seemed like they were doing that every chance they got.
The question fled my mind a moment later when Dad swaggered in, completely naked, of course. His tentacle cock hung limp between his thighs, and its fat head smacked his knees as he walked. It seemed to be leaking pre-cum, and from the milky streaks and smears on his knees, lower legs and feet, it appeared to have been doing so for a while. The sight of it, not to mention the smell of it -- because I could clearly smell it, and even recognize the odor as not just that of pre-cum, but of Dad's pre-cum -- instantly turned me on. Suddenly, I realized that, unlike yesterday, the feeling brought almost no backlash. I could sense a measure of disgust welling up in that still lucid part of me, but only a measure, and it was so distant that I hardly felt it.
"Rise and shine, Timmy," Dad ordered. "We're out of here in a few." He seemed to be doing a final look-through to make sure we hadn't forgotten anything. That seemed so much like the old Dad that it made me wonder for a moment whether there might after all be something of the man he had been left somewhere inside. Was there a still lucid part of him buried deep beneath the sadistic creature into which he had been transformed, its impulses occasionally breaking through to the surface?
"Yeff, Daad," I answered reflexively, my tongue still feeling way too large for my mouth. Dad turned to me and smiled, another one of those cruel, lascivious smiles. The look he gave me drove away any thought of part of the old Dad somehow remaining inside.
"Tongue feeling a bit heavy this morning, son?" he asked, as one might ask 'sleep well last night?' I nodded. "Excellent, you're coming along nicely. I knew you would. It's definitely time to head home."
I immediately got a sinking feeling and wanted to ask what he meant by that, but I didn't think I could get the words out. In any event, he didn't give me the chance. Turning, he swaggered out of the room. "Looks good in here," he called out. "Nothing left behind, except for Timmy, who'll be up in a minute."
Dad's order had left me with no choice. I could feel my muscles beginning to flex to move my limbs in response to Dad's command to get up. The feeling was incredibly strange and left me in no doubt that resistance would have been futile. Slowly, I threw off the thin sheet, and I got to my feet. Standing felt more awkward than ever. My muscles and joints were strangely soar, not painfully so, but it felt as if I had had a rigorous work out. Suddenly recalling some additional detail of yesterday's events, I cringed. I supposed, in a way, I had. The soreness, though, was especially acute in my arms, chest and groin. Looking down, I found that my arms and shoulders bulged with new muscle, and that my arms appeared to have grown longer. I didn't have time to wonder how. If the question had time to take form, it was immediately driven from my mind when my eyes made sense of what was partially obscuring my view of my feet: two humps the size of half-melons bulging from my chest, and capped by fleshy protrusions so long and thick they almost looked more like teats than nipples. What the....!? How the...!?
When I had recovered sufficiently to look passed them down to my groin, I found a monstrously long bat of a thing dangling in front of testicles larger than Dad's. it was still very much phallic in shape, but it looked oddly smooth, its head having almost merged seamlessly with the shaft. Stranger and more horrifying still, my cock no longer seemed to be growing from the middle of my groin. Its base seemed to have moved over to one side a little. Beside it, an engorged helmet-like shape that looked very much like a second cockhead seemed to be growing out. I stared in shock at my new body.
