Rays of sun came in through the window between the curtains, showing the dust that danced silently as it fell through the air.
I stretched my arms straight out as I yawned and woke up from the best sleep I’ve had in ages. I delighted in the feeling of my huge muscles as they bulged and flexed through my stretching. Erik was already up and about, as he was the earlier bird in the relationship.
I struggled to prop myself up into a sitting position, my mobility limited by the massive mounds that were now packed onto my frame. My oversized schlong draped over my yoga ball sized balls and onto the floor. It was still hard to believe what had happened yesterday.
I stood up and walked to the door and was presented with the first problem of my new dimensions. Being as wide as a king-sized bed came with mobility issues. I turned sideways and started to shuffle through the door, but it still took some wiggling and maneuvering to fit my expanded pecs through the width of the frame. I was worried I may have gotten stuck halfway when the door jamb got wedged between huge mounds of muscle, but eventually I made it through.
Erik was gone, most likely running errands. Making coffee at this size was chore. My biceps and pecs fought for space as I tried pick this up, forcing me to resort to twisting my upper body to grab on to the tools and ingredients necessary. Even drinking the beverage now required a straw because my hand couldn’t quite reach my face.
As I sat on the creaking, groaning couch and watched TV, I could feel some stiffness start to be released around my neck. A couple minutes later, I instinctually brought the coffee mug to my lips and took a sip without the straw. That’s odd, I couldn’t do that earlier. Perhaps I was getting used to the enlarged size.
But when I looked back to the TV screen, I saw the head of my cock was being pulled towards me, as though it were a fishing line being reeled in. I got up and went to the bathroom, without getting stuck. I looked into the mirror and saw that my once gargantuan muscles were now smaller. Still huge, but smaller. And they continued to lose size as I watched, unable to understand what was happening. I had mixed feelings as I watched the slow shrinking of my muscles. On the one hand, it was a pain to maneuver the world at such a hulking size. On the other, I really like being a huge muscle beast.
Erik entered the apartment, and I called for.
“What’s happening! Why are you shrinking!?”
“I don’t know! It started a few minutes ago and I don’t know how to stop it.” The reflection now showed a man the size of a 300-pound bodybuilder, with a 2-foot dick the circumference of a soda bottle.
In my head I was going over everything I could remember from yesterday. “Where did you go just now?” I asked Erik.
“I was just at the laundromat across the street. We desperately needed clean clothes, and everything smelled after what happened last night.”
Then it clicked. I picked up the product tag that I left on the dining table, showed it to Erik, and pointed to one of the bullet points.
“Washing may cause shrinking!” he said as he looked up to me. I could tell he wasn’t thrilled about my changing body composition.
“I guess you put that jockstrap in the washing machine, huh?”
“Yeah, it’s being washed as we speak.”
I was now the size of an Olympic gymnast, with a 14 incher between my legs.
“Don’t be sad, we’ll probably be able to do this all over again! Besides, how was I going to go about daily life when I was bigger than the hulk and more hung than a blue whale?”
“I guess so…” Erik was so dejected. He looked like a kid who was just told why couldn’t have ice cream for dinner.
My body finally stopped shrinking. “I guess the laundry is being washed.”
Looking myself over, I wasn’t completely back to the way I was. There was still some muscle on me, and my dick was definitely a couple inches bigger than usual, closer to Erik’s impressive natural size. I had a swimmer’s build, muscled but not big.
“I guess the machine didn’t do a very good job,” I said to Erik then winked. I could see the gears in his head turning. He was planning something.
A devious smile split his face. “Pack your things, we’re going to spend the weekend at my parent’s cottage.
The cottage was a classic log cabin that sat on the edge of a small lake shared with no one else. It was a remote location with the next closest neighbour being miles away. It was Erik’s family’s remote getaway surrounded by forest and pristine nature. After following the long, winding dirt road from the highway to the cottage, we unpacked our supplies.
Being outside the air-conditioned car and hauling our supplies into the cottage guaranteed some more muscle growth. Erik stood back and watched, ensuring that all the sweaty labour was done by me. Although with every trip between the car and the cottage, our supplies started to feel lighter and lighter. My medium t-shirt was now starting to look like a second skin. My broad shoulders pulled the sleeves higher up my arms. The sleeves bunched up over my larger biceps and triceps, causing the sleeves to only cover my shoulder muscles. My chest had thickened and caused the fabric to stretch and pull under my arms. My pecs now took up more space than the t-shirt was designed for, and the lowest two rows of my abs were now exposed, causing my once loose t-shirt to look more like a crop top. My shorts were fairing no better, with my muscle butt taking up space and causing the hem of the shorts to climb higher. The bulge stuck out in front of me as far as my shelf-like pecs, creases appearing around my pelvis as my shorts tried desperately to maintain their shape.
Standing by the front of the cottage, Erik stood there and drank in my form and admired the musculature as I finished the last load of supplies. Erik then walked up to me and cupped my substantial bulge with his hands and whispered “Let’s get you out of those clothes” with a sultry look.
I instinctively reached down to start pulling my shirt over my head, but Erik grabbed my hands and said “ah ah ahh” and wagged his finger at me. I gave him a confused look.
“You won’t be taking off your clothes that way.”
He then pointed to the woodpile next to the cabin. There was no way we would need a fire to warm up the cabin in this heatwave, but my brain made the connection and I understood what he wanted.
I proceeded to swagger over to the stump with the axe stuck in it. I pulled the axe out and set up a log to swing at. I set to work splitting wood, bending low to show Erik my round, muscled ass every time I needed pick up another log. Swing after swing in the beating sun of the early afternoon works up quite the sweat. Before long, the clothes I’m wearing start to pop and strain around my growing muscles. The sleeves bunched around my biceps began to split. Soon after, the seams along my torso split, leaving the shirt hanging around my neck like a bib, only covering the deep valley between my thick pecs.
My shorts were uncomfortably tight, but I know this discomfort won’t last long. My thighs and ass were taking up more and more space in the legs of my shorts, leaving less room for my bits up front. But I keow how to relieve some pressure. For the next log, I squatted down as deep as I can, nearly touching the ground with my ass. With a loud rip, the pants split right down the middle, from back to front. The pouch of my jockstrap tumbled out and made contact with the ground between my feet, sending shivers up my spine. As I lifted myself out of the squat, my quads flare and rip the inseams, releasing the pressure my clothes put on my lower half.
I walked back over to Erik with a smile on my face. He was biting his lower lip as he watched me move towards him in nothing but the tattered remains of my clothing. When I was a few feet away from him, his smile turned mischievous. His hands were crossed over his chest.
“I have a surprise for you.”
“Oh? And what’s that?”
He took a step forward to close the gap between us. His hands moved down to the pouch of my jockstrap and he proceeded to rub his hands over my protruding bulge. His arms had been crossed because he wanted his hands in his armpits, collecting sweat. I gave a mock gasp of incredulity as my muscles were hit with an intense wave of growth. The clothes that remained around my neck and hips started to groan as my muscles start to stretch them beyond their limits. Erik groped at my chest as it expanded before his eyes.
“So this was your plan all along,” I said with one eyebrow raised.
“Maybeee,” he said as he wrapped himself around my growing form. I thought he was hugging me to feel all my muscles swell, which may have been partially true. But just like the previous night, I could feel his hands guiding the sweat from my wide back into the waistband of the jockstrap, all while he grinds his hard dick into my bulge.
The stimulation from the growth mixed with Erik’s grinding caused me to get hard too. Erik pulled his pants down, revealing his stiff member before continuing. My own stiffening member reached down to my knees. Erik was going absolutely wild, trying as hard as he could to force me to grow. He could no longer touch his hands together behind my back, my chest and lats too thick to allow it. When he realized this, he opted to bury his face into the deepening crevice between my pecs.
Erik, who hadn’t orgasmed since last night, was first to release load. He of course aimed it at my crotch to ensure our growth saga continued to his liking. Once again, my dick started to swell. Erik held it down by straddling it between his legs. Meanwhile, I was on cloud nine, letting the pleasure of my growing cock wash over me. It grew thicker and longer, sticking out behind Erik’s back by at least a foot.
When the growth subsided and everything settled, my cock was pulled back by the stretchy material and Erik took a step away to get a good look at me. I was now more muscled than any bodybuilder, looking more like a bodybuilder who had been morphed to inhuman proportions. My arms were now 25 inches around, dwarfing my head. My thighs were now 30 inches around, nearly as thick as my old waist size.
But the biggest change was between my legs. With my cock finally soft, and the jockstrap doing its best to hold everything, the pouch had to be at least the size of a yoga ball.
Erik stood looking at me with wonder in his eyes. I was becoming his dream come true, and I loved being the one to make that dream come true for him. Becoming masculinity incarnate was also very exciting.
“Look at you. You’re the hottest man I’ve ever seen,” he said, his smile wide.
“And I’ve only just started.”
