Chapter 1: Protein Shake Surprise
The fridge hummed, a low and steady vibration against my bare shoulder. The cool metal was the only thing keeping me upright. My eyes were squeezed shut, one hand braced against the appliance door, the other working in a fast, familiar rhythm underneath the loose waistband of my boxers.
It was Tuesday. The kitchen was a monument to our shared entropy. Stu’s empty protein shakers stood in a sad battalion by the sink, next to my cereal bowl from three days ago, the milk now a solidified science experiment. The counter was a graveyard of crumpled energy bar wrappers and, for some reason, a single dirty sock of mine.
My breath hitched. Almost there.
The front door slammed open. A gym bag hit the floorboards with a thud heavy enough to rattle the cutlery in the drawer.
“Mikey?”
Stu’s voice, clipped and already annoyed. Panic shot through me, sharp and electric. I scrambled, my mind blanking. My gaze darted around the clutter-fogged kitchen, landing on the nearest clean-ish vessel: Stu’s stainless steel protein shaker, lid off, waiting on the counter next to a tub of vanilla-flavored powder.
It was a terrible, brilliant, instinctive solution.
I grabbed it just as the climax ripped through me. I stifled a groan into my bicep, pressed against the fridge. Thick, hot pulses spurted into the chilled metal cup, a stark white against the shiny silver interior. The sound was impossibly loud in my head.
Footsteps approached.
I dropped the shaker back on the counter, yanked my boxers up, and spun around, leaning against the fridge as if I’d been contemplating the condiment shelf for meaning. My heart hammered against my ribs.
Stu walked in, a wall of concentrated irritation. He was already in his gym gear, tight across his chest and shoulders, a towel draped around his neck. His dark hair was damp from a pre-workout shower. He looked like a brochure for discipline, and he smelled like lemongrass soap and simmering frustration.
“What are you doing?” he asked, his eyes scanning the mess, skimming right over me and the shaker.
“Strategizing my next meal,” I said, my voice miraculously steady. I gestured vaguely at the fridge. “The options are bleak, my friend. It’s a culinary wasteland in there.”
He grunted, not listening. He moved past me, a man on a mission. His focus was absolute. He snatched the tub of protein powder, peeled back the foil, and dug the scoop in.
“You’re going now?” I asked, watching his hands. My own felt clammy. “Isn’t it, like, preacher curl o’clock or something?”
“My schedule’s shifted,” he said, voice tight. He dumped two heaped scoops of the vanilla powder into the shaker. The white dust settled over my contribution. “Need to shock the system. Plateaus are a mental failure.”
He said things like that. Mental failure. I usually laughed. Right now, I just watched, mesmerized and horrified, as he reached for the carton of almond milk.
“You want a spot?” The question was automatic, a flatmate reflex.
“No.” He poured the milk into the shaker, the liquid swirling, mixing everything into a homogeneous, off-white slurry. He clapped the lid on—a harsh, final sound—and began shaking it with a violent, practiced intensity. Swish-swish-thwack. Swish-swish-thwack.
The sound was obscene. I felt a hysterical laugh bubble in my throat and swallowed it down.
He stopped shaking, unscrewed the lid, and without a second’s pause, brought it to his lips. He took a long, deep pull. His Adam’s apple bobbed. He drank like it was medicine, his eyes fixed on some point beyond the kitchen wall, probably visualizing increased protein synthesis.
He lowered the shaker, licked his lips. A tiny droplet clung to his stubble. He frowned, slightly.
“Taste okay?” I asked. The words came out too high.
“Fine.” He took another swallow, then another, draining about half of it. “A bit… richer than usual. Must be a new batch of powder.”
“Probably.”
He set the half-empty shaker down with a clank. The metal was already beading with condensation. My DNA was in there, swirling with his almond milk and his vanilla dreams. He wiped his mouth with the back of his hand, a grim determination settling over his features. The frustration from a moment ago was gone, replaced by a focused drive.
“Right,” he said, picking up his gym bag. “Back in two hours. Don’t order pizza. I’ve pre-weighed my chicken.”
“The nation weeps for your chicken,” I muttered.
He didn’t hear me. He was already gone, the front door closing with a solid, respectable click.
I stood alone in the silent kitchen. The only sound was the fridge’s persistent hum. I looked at the shaker. I looked at my sock on the counter. A slow, disbelieving grin spread across my face. It was the most absurd thing I had ever done. And he had no idea. None.
The laugh finally escaped, a short, sharp burst that echoed in the empty room.
I spent the next two hours in a state of low-grade, surreal anxiety. I half-expected Stu to come storming back in, having somehow sensed the violation, ready to murder me with a dumbbell. I cleaned the kitchen, for once. I even washed my sock. It felt like a bizarre form of penance.
When the door opened again, he didn’t storm. He walked in slowly. His posture was different. Not slumped, but… unlocked. The grim set of his jaw was gone. He looked… vibrant.
He dropped his bag gently. He looked at his hands, turning them over as if seeing them for the first time.
“You okay?” I asked from the couch, trying to sound casual. “You look… flushed.”
“I had the best workout of my life,” he said, his voice quiet with awe. He wasn’t talking to me, not really. He was stating a fact to the universe. “It was… incredible. The pump. The endurance. I shattered every plateau. I added ten pounds to my bench. For reps.”
He finally looked at me. His eyes, usually so focused and serious, were lit with something unfamiliar. A pure, unadulterated triumph.
“That’s awesome, man,” I said. “Must’ve been the new powder.”
“It wasn’t the powder.” He walked into the kitchen, his movements fluid, powerful. He went straight to the sink, where the empty shaker sat, rinsed and waiting. He picked it up. He stared at it.
His gaze, thoughtful and intense, lifted from the steel cup and settled on me.
A long, silent moment stretched between us. The hum of the fridge filled the space. He didn’t look angry. He didn’t look disgusted. He looked like a scientist who had just stumbled upon a radical, inexplicable, and undeniably effective new formula.
He took a slow, deep breath, his broad chest expanding under his tight shirt.
“Mikey,” he said. His tone was deadly serious, stripped of all its usual bluntness. It was the voice he used when discussing macro-nutrient ratios. “We need to talk about what happened.”
The way he said it—calm, analytical—made my skin prickle. My grin froze, then melted away. He wasn’t holding the shaker like evidence. He was holding it like a relic.
“What do you mean?” I tried for casual, leaning back into the couch cushions. “You crushed your workout. That’s what happened. End of story.”
“No.” He took a step closer, his eyes never leaving mine. The focused look was back, but it was laser-directed now, pinning me in place. “It’s not. My body doesn’t lie. That wasn’t a normal pump. That wasn’t a placebo. Something was different.” He glanced at the shaker, then back at me. “The only variable that was different today was this.”
“It was new powder, you said it yourself!” I heard the defensiveness in my voice and winced.
“The powder is from a bulk container I opened three weeks ago.” His voice was flat. “The almond milk is the same brand. The only thing that changed was the time of day I drank it, and you being in here when I made it.”
He placed the shaker on the coffee table between us with a soft, definitive click. The sound was absurdly loud.
“So I’ll ask you plainly, Mikey.” He crossed his arms, his biceps straining the sleeves of his shirt. The casual posture was a contrast to the intensity in his eyes. “What did you put in my shake?”
The air in the room got thick. I could smell the faint, sour tang of old milk from my abandoned cereal bowl. I could hear the drip of the kitchen tap I never fixed. My mind raced through a dozen lies—a dash of creatine, a hit of pre-workout, a secret ingredient from a blog. But they all crumbled under the sheer weight of his scrutiny. He would know. He knew the contents of our cupboards like a chemist.
I let out a long, shaky breath. The laugh I’d stifled earlier was gone, replaced by a cold lump in my stomach.
“Look, man,” I started, rubbing the back of my neck. “It was a stupid, split-second thing. A panic move. It wasn’t malicious.”
His brow furrowed. “What are you talking about?”
“When you came in… I wasn’t strategizing my next meal.” I gestured weakly toward the fridge. “I was, you know. Taking care of business. Against the fridge. And you barged in, and I panicked, and the shaker was right there…”
I watched the words land. For a second, nothing. Just blank processing. His serious face parsed the sentence, piecing together the fragments: against the fridge… taking care of business… the shaker was right there…
His expression shifted.
The color drained from his face, then rushed back in a dark, furious flush. His eyes widened, then narrowed into slits. The focused curiosity evaporated, replaced by pure, unadulterated horror.
“You did what?”
The question wasn’t loud. It was a low, gravelly scrape of sound. He uncrossed his arms, his hands curling into fists at his sides.
“It was an accident! A reaction!” I was babbling now, sitting forward on the couch. “I didn’t plan it. You were about to walk in on me, and I just… I grabbed the first thing I saw to… contain the situation.”
“Contain the situation,” he repeated, his voice dripping with a disgust so profound it felt physical. He looked at the shaker, then at his own hands. He brought a hand up slowly, staring at his palm as if it were contaminated. “You… you ejaculated into my protein shaker. And then I… I drank it.”
He said it aloud, making it real. The clinical words in his mouth made the whole thing ten times worse.
“Oh, god.” He turned away from me, stumbling a step toward the kitchen. He braced his hands on the counter, head hanging down between his shoulders. His back muscles were rigid, coiled tight. “I drank it. I drank your… and I felt… I felt amazing.”
The last word was a snarl of self-loathing. He whirled back around. The anger now was hot and bright, burning away the initial shock. His eyes were wild.
“Are you insane? Are you actually a fucking animal? What is wrong with you?”
“Nothing is wrong with me! Something is clearly right with you!” The retort shot out of me before I could stop it. “You said it was the best workout of your life! You added ten pounds!”
“Don’t you dare!” He took a threatening step forward. “Don’t you dare try to spin this into some kind of… of biohack! That’s disgusting! That’s a violation! I consumed a… a bodily fluid without my knowledge or consent! Do you have any idea how fucked up that is?”
I shrunk back. I did know. Of course I knew. The absurdity of the moment had shielded me from the gravity of it. Now, seeing the raw betrayal and revulsion on his face, it hit me like a punch.
“I’m sorry,” I said, and it sounded pathetic. “Stu, I am so, so sorry. I wasn’t thinking.”
“You never think!” he roared, finally raising his voice. It bounced off the dirty plates in the sink. “You just float through this place leaving a trail of mess and… and biological waste everywhere! My shaker, Mikey! My post-workout ritual!”
He grabbed the shaker from the table, holding it aloft like it was a crime scene exhibit. “This is unforgivable.”
Then he stopped. He stared at the metal cylinder in his hand. His breathing was ragged, his chest heaving. The furious energy seemed to drain from him all at once, replaced by something colder, more calculating. The horror in his eyes flickered, mixed with something else—a terrible, dawning curiosity.
He looked from the shaker to me, his gaze travelling over me with a new, awful intensity. Not as his messy flatmate. But as a source.
The silence that followed was heavier than his shouting. It was filled with the grotesque truth hanging between us, and the undeniable, world-altering result now coursing through his veins.
He lowered the shaker. His voice, when it came, was quiet again, but strained tight with a conflict I could barely comprehend.
“It can’t be that,” he muttered, almost to himself. “It makes no physiological sense. But the correlation…”
He looked at me, really looked at me, and I saw the war behind his eyes: utter disgust wrestling with insatiable, results-driven need.
The chapter ends here.
