Slim Chance 3 - Chapter 5

Chapter 5

I stumbled back, fear twisting my guts like the blades of a blender. This could not be happening. Why was Amanda here? Why was I small again? This had to be a nightmare. But no, I was not smaller. The basketball clutched in my sweaty palms was proof of that. It was Amanda that had grown, she was colossal! She took a step forward with a heavy thump that vibrated the court beneath my feet and put my nose even with the crotch of her jumpsuit. Her thick thighs and mons pubis created dark crevices where the V of her sex swallowed the grey material. Lines of stress radiated from her mound as though the pants could not contain her overflowing sexuality. A voice gibbered something incomprehensible and Amanda’s mouth quirked in a tight-lipped smile. With a start I realized the babbling voice was mine.

“Aww, so happy to see me you’re speechless,” Amanda mocked, voice booming effortlessly. It finally sank in that this was not a dream. My sister was surreally enormous but she was real. And she was going to take everything away from me. Again. I did the only thing I could

I ran.

My sneakers squeaked shrilly as I dashed across the court with every ounce of speed my spindly body could muster. My sudden flight must have caught Amanda off-guard because her booming steps were slow to pursue. The court creaked beneath her weight, a sound that traveled through the boards like a glacier cracking. I made it to the door to the swimming pool before her third step thundered against the floor and wrenched it open. A panicked breath flooded my sinuses with the smell of chlorine. On the opposite end of the pool were two small entryways- a sauna? Showers? EIther way, salvation. Amanda was too big to fit through those doors.

I ran full tilt towards sanctuary- and slipped.

My sneakers slid over the tile like butter on a hot pan. The edge of the pool rushed towards me and then I was airborne, arms cartwheeling uselessly as I collided with the water. Bubble exploded around my head and I gasped, sucking in water and kicking my feet in a panic. For a terrified moment I had no idea which way up but my hand found the bottom of the pool and I pushed, righting myself then thrusting off the bottom with both legs. I broke the surface coughing and sputtering chlorine laced water from lungs. My vision was blurred with water but not so much that I failed to see Amanda’s huge form slowly stroll to the edge of the pool. 

“Wow bro, you really wanted to go for a swim, huh?” Even through the water dripping over my eyes I could see Amanda’s mocking smile. “Well I don’t want to get my clothes wet, so…” While I tread water and coughed my lungs out Amanda stripped out of her jumpsuit revealing a body that was much as I remembered it. It was like I had not grown at all. No! I could not allow myself to think that way. Amanda was bigger. Her ass was the size of two fully inflated beach balls and each of her tits was as big as my head. Her thighs were so thick that I would need both arms to encircle one. 

I tore my eyes away and paddled desperately towards the opposite side of the pool. Swamped with water my workout clothes dragged me down, making every movement slow and clumsy. Water splashed and a large wave rolled past me and I redoubled my effort, kicking and clawing at the water. I was a foot away from the edge of the pool when something encircled my ankle. “No!” I shouted and lurched forward, making a final desperate grab for the edge. I may as well have tried to touch the moon, I did not budge an inch. “Nooooooooo!” my terrified voice echoed across the pool.

“Ugh, quit being such a cry baby. I was starting to think you might not be less pathetic since you got a little bigger, but I guess I was wrong.”

“Let me go!” I howled. 

In response Amanda tugged backward, and I went skimming across the surface of the water as though I were being hauled behind a boat. My thigh bumped into something wet and flesh and I twisted frantically, rolling over in the water and finding Amanda’s glare. Our eyes locked and the annoyance slowly drained from her expression even as mine undoubtedly filled with horror. She smiled, and it was a horror-fueled parting of her lips, a smile that promised suffering and torment and sadism. My muscles stiffened, I felt faint and… Water splashed against my face. “Snap out of it, runt. You’re not getting out of this that easy.”   

“Wha…?” I snapped out of my stupor and realized I had lost consciousness. I struggled to sit up and could not get my balance, Amanda still held one ankle tightly and it was all I could do to tread water to keep my head from slipping under.

“Is that any way to greet your goddess?” Amanda said. Goddess? I had nearly forgotten how full of herself my sister had become and my expression must have given away my surprise because she went on. “Alan says it’s only a matter of time before millions of people worship me. I already had thousands of pathetic little worshippers, but don’t worry runt, I know you were one of the first.”

“I don’t worship you!” I snapped. “You’re just- just… A bully!” 

Amanda snorted derisively then grabbed my free leg and pulled until that my legs were spread painfully wide around her torso. Her plump breasts bobbed between my legs with the rest of her body submerged beneath their wobbling mass. The water’s rippling surface distorted her form into an otherworldly shadow, a leviathan lurking in the depths. Amanda’s fingers hooked beneath my work out shorts and pulled and I squealed in pain. A wedgie gave way to tearing fabric and Amanda spoke casually, “I was not expecting to see you here, runt, but I’m glad you came.” She finished ripping the shorts off of me and started on my underwear. “Alan says we have to be careful or people will come after me before we’re ready.”

“Ready for what?” I was amazed to hear the sound of my own voice.

Amanda barked a dismissive laugh. “Wouldn’t you like to know. Anyway, it’s good that you’re here because you’ll keep your mouth shut. It’ll be just like before.”

No! No! No! I could not go back, not after everything I had been through. “Let go of me!” I shouted, thrashing my legs against her to little effect. Her hands swallowed my ankles like a pair of popsicle sticks and her strength! I might as well have been shackled to a wall for all the difference my struggling made to Amanda, not only did her arms not budge- judging by the contemplative look on her face she did not even notice I was fighting her! Chlorine stung the corners of my eyes and water ran down my cheeks. It was the pool, I definitely was not crying.

“Let’s get this over with,” Amanda said disinterestedly, and plunged her mouth over my cock.

A convulsion of pure shock pulsed through me and I jerked in her hands, unpinned arms splashing water all around us. Amanda hauled up on my legs, pulling my crotch closer to her mouth and tilting my head under the water. My panicked thrashing quickly turned to desperate paddling to keep my head above water. Meanwhile huge Amanda’s tongue wrapped around my shaft like she was trying to suck the head off a sucker. My dick began to harden and fresh panic rose into my throat. Her mouth sucked and stroked, saliva swishing around my shaft when her cheeks hollowed to suck tempestuously. 

If this continued Amanda was going to take everything away again. My size, my dignity, my freedom. No! A part of me screamed in defiance. The same part I had been nurturing for months, the nugget of discipline I had grown from a tiny seed into a mighty oak of resolve. I would not let her do this to me, not again. I hooked my ankles around her back, using the strength of my legs to leverage my core upward and simultaneously relaxing the struggle my arms had to endure to keep my head above water. I would not be able to maintain the position for long, but it would have to be enough. Anchored, I turned my focus inward and steadied my breathing. In. Out. In. Out. I am in control. I want for nothing. My seed is life. Life must be preserved. 

Amanda’s tongue continued its devilish work, but the wet serpent felt hazy- distant. My erection begin to soften. It was working! Amanda redoubled her efforts but my focus was complete, I was… I was winning! She grunted, frustration making her technique sloppy and brutish, the suction of her mouth grew suddenly violent. Pain blossomed at the root of my dick and I gasped, my concentration broken. It did not matter, with my penis aching in a way that was anything but pleasurable there was little risk that she could coax me back to life. A thrill of pure elation built inside until I felt I would burst from it. I relaxed my legs and, sucking in a deep breath, plunged back under the water and let out a triumphant shout that rose from my mouth in a cloud of bubbles.          

Amanda yanked me out of the water before I was done and cut off with a gurgle. Her hands wrapped around my arms and she hauled me up to meet her furious eyes. They blazed with shock and outrage, her lips twisted with spite that went well beyond her typical disdain. “What did you do, runt?” she snarled. I shrugged and looked away, a lump forming in my throat. She was really pissed, I don’t know if I had ever seen her this angry. “Did you find some new drug to keep you flaccid? Some anti-viagra or something? Is that it?”

Did such a thing exist? A bolt of inspiration hit me, it didn’t matter if it did or not. If Amanda thought I was physically incapable of maintaining an erection she would have to give up. “Yes,” I gasped, spitting out water. “It’s a special drug, there is nothing you or I can do about it.” Somehow I managed to maintain eye contact with her and after a long moment Amanda made a disgusted sound and dropped me. I splashed back into the pool and swallowed another mouthful of acidic water before bobbing back to the surface. Amanda glared down at me as though I were a bug she was deciding how to kill. Her eyes widened slightly as something occurred to her and a slow, chilling smile revealed her teeth. “I got you hard with my mouth so you can still feel something,” Amanda said with a cold clinicism that made my skin crawl. “How long do you think that stuff can hold out against my best ASSet.” 

All I could do was stare at her in stupefied horror as her hand once more encircled my ankle and she began to haul me across the pool. I repeatedly dipped under the surface and had to struggle desperately just to keep air in my lungs. The next thing I knew I was being flopped onto a narrow platform. Coughing and sputtering I coughed and wretched the pool water out of my sinuses while Amanda extracted herself from the pool. By the time I rolled onto my back she was stepping up onto the platform with me. Her first step tilted the entire platform down and I felt water splash against my scalp, the entire thing creaked alarmingly. I’m on the diving board, I realized with a start. It was the low-slung kind and was only raised a couple feet out of the water at most. Amanda tested it again with her foot, nearly plunging my head under water with a shove. The board catapulted back into place and would have flung me at Amanda if I had not clung to it with a death grip. Amanda turned away from me and took hold of the chrome rails on either side of the board. 

Her ass floated above me, twin boulders that were every bit as enormous as I remembered. I had grown so much, they shouldn’t be so big compared to me but there they were. Fat, heavy, and undeniable. The cheeks exploded from her upper thighs in a dramatic curve that emphasized how round they were. The enormous glutes completely filled the space provided by her hips and Amanda hips were many feet wide. Naked, the fleshy zeppelins dimpled with Amanda’s movement, shedding drops of pool water as they wobbled into position over me. “You are gonna make me bigger, runt.” Amanda said, emphasizing ‘are’ in a way that made it clear my earlier hope was fruitless. Amanda was not viewing the fictional drug as a dead end, but as a challenge.   

The gargantuan globes of her ass began to descend my body fell into shadow. The teal diving board seemed to rise up to meet her colossal backside and I had the uncanny impression of a thong sliding between her cheeks. Amanda’s ass was so enormous the diving board was not going to stop it, it was going to split it! With a grunt of effort Amanda slammed her ass down. A sharp pain radiated out from my groin as her cheeks parted, the diving board and my lower body disappearing into the crack of her ass. A wall of flesh swelled over me, the weight of her ass crushing first my pelvis, then my abdomen, and finally coming to rest against my ribs. The size of it was mind boggling- covering my entire midsection and hanging over the edges of the diving board. The board made dangerous popping and creaking sounds and air exploded from my lungs in a gasp.

Amanda weight settled and I wheezed. “Stop!” I pleaded, “You’re crushing me.” 

“Shutup, twerp. You love this. You live to worship my ass.” No, I wanted to shout. I’m a different person, I’m in control! But my air was gone and I could only gurgle in pain. The edges of my vision began to darken when the immense pressure on my stomach suddenly lifted. Thick fingers probed my groin, taking hold of my limp member. It felt like it was being rolled back and forth the way one would roll a cigarette. “Look at it, runt. Look at my ass.” Even without Amanda telling me to look there was not anything else I could see. Her rear hung over me like a meteor waiting to fall, filling my sight. Water dripped from the bloated orbs onto my chest and I could  even make out the fine hairs that furred the interior of her crack.

Her cheeks wobbled as she began to jerk and stroke my dick. I squeezed my eyes shut, seeking my center, my focus. I am in- “Don’t you want to see it get bigger, runt?” Amanda growled. I clung desperately to my mantra, I want for- “You want to get so small you fit in my ass again?” My seed is- “You want to live in my ass don’t you? Like a little parasite.” Life must be preserv- “There we go!” Amanda crowed happily. “Nice and hard.” I whimpered, while she spoke my cock had grown rigid and now strained in her grip. Her hand swallowed my length easily and she stroked a couple more times before standing suddenly. My back arched, my hips thrusting pathetically upward to pursue her retreating hand. A noise slipped from my throat, high pitched and animalistic.

“Quit whining,” Amanda barked as she gripped the chrome rails in either hand and squared her feet on either side of the diving board. Her ass wobbled down the length of my body as she repositioned. “You don’t deserve this,” she said coldly. Then, in a sudden surge of motion, Amanda dropped her pussy straight down onto my shaft. My member plunged into her depths, the walls of her sex accepting my length without any resistance. The diving board bounced downward, the tip slapping the top of the water. My cock pulled almost completely free then abruptly rebounded with enough force to hurt my hips as I slammed back into Amanda. The impact forced my upper body against the immovable boulders of her ass and only the fact that they were plump with fat spared me from serious injury. 

Amanda slammed her ass down again, forcing my body and the diving board to absorb the impact. Then she simply held position as the diving board rocketed back into place, once more ramming my dick home into her sex. I clung helplessly to the board as Amanda fell into a rhythm, using the diving board’s recoil to fuck herself. I had thought I was too big, too independent, too focused to ever be used Amanda’s sex toy again. But here we were, her ass crashing down on me- barely rippling with the impact while my stomach and hips were battered and bruised by her overgrown glutes. And the worst part- it was working.

Amanda’s incredible ass, so big I could not see anything else bounced and jiggled. The diving board creaked and groaned and popped. White hot plasma stirred to life in my loins, like water long simmering finally coming to a boil. A part of my mind screamed in defiance, then terror. The rest of me felt strangely calm. Months of the constantly fighting myself, the rigid discipline, the endless vigilance- it had been exhausting. Now all I had to do was let go and-

My vision fuzzed as the most powerful orgasm of my life ripped through my body like a hurricane. Spunk so hot it might as well have been magma erupted from my dick in long, draining spurts. Amanda’s fat ass continued to bounce, swallowing half my body into her crack every time the board catapulted my body upward. The room spun sickeningly and that old familiar feeling of nausea descended on me. It grew worse, I felt like every muscle in my body was hot and cold, pins and needles. 

Horror finally overcame pleasure and I cried out as my body started to shrink, faster than ever before.
