Lungs of Green Sawdust

I’m too old for this, Steve thought, staring at his reflection in the polished chrome of the toaster. His skin looked like a topographical map of a life spent mostly in the sun, and the new tiny home was supposed to be the final chapter—the clean, minimalist edit of a messy existence. Then came Jared. Jared with the high-fade haircut and the smile that felt like an investment opportunity. At fifty-five, Steve knew better than to fall for a thirty-year-old bio-engineer who talked in acronyms, yet here he was, flushed and waiting. The air in the woods was thick with the scent of pine and something heavier, something sweet and rotting that signaled the true arrival of spring. It was the kind of day where the pollen sat on the surface of the pond like yellow grease.

Jared arrived at the gravel driveway carrying a ceramic pot. He didn't walk; he bounced. Every movement was optimized. He set the pot on the cedar deck, the plant inside a frantic tangle of translucent leaves and thick, purple-veined stems. "It’s a prototype," Jared said, his voice dropping into that low, confidential register that always made Steve’s stomach do a slow roll. "From the Boreal Springboard lab. I wanted you to have the first one. It’s a carbon-sequestering beast, Steve. It literally cleans the air. But better than that? It responds to the environment. It feeds on carbon dioxide and, honestly, positive vibes. If the room is happy, it thrives."

Steve looked at the plant. It didn't look like any fern or ivy he’d ever seen. It looked like a cluster of lungs held together by wire. "Positive vibes?" Steve asked, trying to sound like he wasn't skeptical. He wanted to be the kind of man who believed in things again. He wanted to be the man Jared saw when Jared looked at him with those bright, predatory eyes. "That’s totally fire, Jared. Really. It’s... beautiful."

"It’s more than beautiful," Jared said, stepping close enough that Steve could smell his expensive, metallic cologne. "It’s a closed-loop system. It learns the occupant. It’ll grow into the space. Think of it as a living roommate that never complains about the dishes."

They spent the afternoon moving the plant to the corner of the loft bed. By evening, the tiny home felt warmer. Not just the temperature, which had spiked to a humid eighty degrees, but the energy. Steve felt a buzzing in his teeth. When Jared left, he promised to check the 'telemetry' from the lab. Steve lay in bed that night, the plant just inches from his pillow. The leaves didn't rustle; they sighed. A soft, rhythmic thrumming vibrated through the mattress, a heartbeat that wasn't his own. He fell asleep thinking about Jared’s hands and woke up feeling like he was drowning in honey.

The next morning, the sunlight through the clerestory windows was filtered through a haze of fine, green dust. Steve stumbled to the kitchenette, his joints stiff. He poured a cup of coffee, the steam rising in the cramped space. As he lifted the mug, he stopped. Floating on the surface of the black liquid was a cluster of glowing, amber spores. They weren't just sitting there; they were spinning, moving in a tight, coordinated circle like a miniature galaxy. He set the cup down, his hand shaking. A movement caught his eye. Through the narrow window that faced the dense treeline, he saw a flash of white. Jared was standing fifty yards away near a thicket of flowering dogwood. He wasn't waving. He was holding a tablet, his face illuminated by the screen's blue glow, staring directly at the house. Steve waved, a hesitant gesture, but Jared didn't react. He just kept typing, his thumb sliding across the glass in a rhythmic, mechanical motion.

Steve turned back to the room and realized the plant had moved. A single, thorny vine had unspooled from the pot and was now threaded through the slats of his bedframe. It looked less like wood and more like muscle. He reached out to touch it, and the vine flinched. It pulled back an inch, the tiny thorns scraping against the wood with a sound like a dry throat trying to swallow. The air was getting thicker. He went to open the front door, but the handle wouldn't budge. He pulled, bracing his feet against the floorboards. The wood had swollen. The frame was tight, the door fused to the jamb as if the entire house had expanded overnight. A bead of sweat rolled down Steve's neck. He smelled damp earth and something metallic—the scent of Jared’s cologne, but amplified, turned sour and organic.

"Jared?" Steve shouted, his voice muffled by the heavy, humid air. "The door's stuck!" He hammered on the glass, but the window felt different now. It wasn't cold silica; it felt warm, slightly yielding, like skin. He looked down at his feet. The floorboards were wet. A clear, viscous fluid was seeping from the gaps between the planks. It pooled around his toes, warm and slightly sticky. The house wasn't just a house anymore. It was becoming soft. The sharp angles of the tiny home were rounding out, the corners filling with a mossy, pulsing growth that looked like internal organs. The plant in the loft had doubled in size, its purple veins glowing with a steady, low-frequency light that matched the thumping in the floor.

There was a sharp rap on the window. It wasn't Jared. It was Officer Westings, the local constable who usually spent his days ticketing tourists. He looked distorted through the humid glass, his face a pale, blurred oval. "Everything alright in there, Steve?" Westings yelled. "Your neighbor called about the smell. Said it smells like a butcher shop in the sun."

Steve tried to scream, but a sudden fit of coughing seized him. He hacked into his palm and found it covered in the same glowing spores he’d seen in his coffee. They were sticky. They clung to his skin, sinking into his pores. "Help!" he managed to wheeze, but the sound was thin. Westings frowned, leaning closer to the glass. Before the officer could react, a vine—thick as a man's wrist—shot out from the ceiling and slammed against the interior of the window, obscuring the view with a fan of broad, wet leaves. Westings stepped back, his hand going to his holster, but he was already losing interest. Steve watched through a tiny gap as Jared stepped out from the trees and placed a hand on the officer's shoulder. They talked for a moment. Jared pointed at the tablet. Westings nodded, laughed, and walked back to his cruiser. He didn't look back.

By nightfall, the loft was gone. The ceiling had sagged until it touched the kitchen counter, creating a fleshy, ribbed tunnel. Steve was pinned against the back wall, his legs entangled in a web of vines that felt like warm veins. The house was breathing now—a long, slow intake of air that made the walls bulge outward, followed by a wet, shivering exhale. He wasn't a homeowner; he was a nutrient. The door finally creaked open, but it didn't swing on hinges. It peeled back like a scab. Jared stepped inside, wearing a plastic apron over his linen shirt. He smelled like a laboratory. He looked at Steve not with love, but with the quiet pride of an engineer watching a bridge hold its first load.

"The humidity is perfect," Jared said, kneeling in the slime that covered the floor. He reached out and stroked a vine that was currently burrowing into Steve's thigh. "The Boreal Springboard is all about integration, Steve. Why build houses when we can grow them? Why have a partner when you can have a symbiont? The carbon-positive lifestyle is finally here. You’re the heart of the home now. Literally. Your pulse is regulating the internal temperature. Your breath is feeding the walls."

"Let me... out," Steve rasped. His tongue felt thick, coated in the green dust. He looked at his arm and saw a tiny, translucent leaf sprouting from a mole on his forearm. It was beautiful in a way that made him want to vomit. The fear was still there, but it was being dampened by a strange, chemical euphoria that the house was pumping into his bloodstream.

"You aren't going anywhere," Jared whispered, leaning in to kiss Steve's forehead. His lips were cold. "The house needs you. It’s a startup, Steve. We all have to make sacrifices for the vision. You're not just living in the future. You are the future. We're going to scale this. Imagine a whole city that breathes with the people inside it. No waste. No separation. Just one big, happy organism."

Jared stood up and checked his tablet one last time. "I’ll be back in the morning to check your vitals. Try to stay positive, okay? The house likes it when you're happy." He stepped out of the fleshy opening, and the door sealed itself shut with a wet, final squelch. Steve lay in the dark, the only light coming from the rhythmic glow of the walls. He felt a sharp tug in his chest. A vine was moving under his ribs, searching for his heart, and for the first time in his life, he didn't feel lonely at all.

The house shifted, the floor tilting as it settled deeper into the damp spring earth, and Steve felt the first digestive enzymes begin to sting his skin.
