Chapter 9: The First Taste

The thick, sweet liquid from the fridge bottle coated his tongue and slid down his throat, leaving a film that tasted of vanilla and chalk. It settled in his stomach, warm and heavy. For a moment, nothing happened. Then the cramps began.

They were deep, internal sutures being pulled taut. He stumbled to the bathroom, the fluorescent light buzzing to life with a sickly flicker. He gripped the stained sink, knuckles white, and watched himself in the mirror as the second wave of the program truly took hold.

His stomach, still flat from a lifetime of negligible appetite, began to swell. It wasn’t bloating. It was a gentle, firm rounding, soft fat layering itself over his abdomen, pushing outward against the thin fabric of his tank top. The cramps migrated, becoming a deep, persistent ache in his hips and ass, a feeling of marrow heating and expanding. He could hear his joints pop, faint wet sounds as the architecture of his pelvis reluctantly adjusted. The reflection showed the gym shorts, already torn, now straining to contain the violent curve of his backside as it plumped and rounded, the cheeks becoming heavy, jutting shelves of flesh.

But it was his chest that commanded attention. The ache there intensified from a throb to a burning pins-and-needles sensation, as if a thousand ants were tunneling beneath his skin, building something. He watched, breath caught in a high, thin whine, as the soft mounds on his chest visibly distended. They grew heavier, lower, their weight a tangible pull on his shoulders. The areolas darkened further, spreading like stains, the nipples swelling into fat, tender nubs that strained against the cotton. He was developing proper breasts—full, pendant, unmistakable.

A voicemail alert chimed. He didn’t move. It played on speaker, Eve’s voice bright and cruel. “Growth spurt uncomfortable, sweetie? That’s the Catalyst syncing with your fat cells. Think of it as targeted nutrition. Now, about Engagement Two. Check your messages. He’s an old friend. Be… receptive.”

A text appeared. A name. Charlie. A number. And a time: Now.

Charlie. From the office. The lanky, affable guy from accounting who’d sometimes tried to include him in useless chatter about sports. Dread, cold and solid, formed in his gut below the new softness of his belly. This was a different violation. This tore into the shreds of his old life.

The doorbell rang, too soon. He wasn’t ready. His body was a foreign landscape of pain and sensitivity. He shuffled to the door, each movement causing the new weight on his chest to sway, the sensation at once grotesque and oddly mesmerizing. He opened it.

Charlie stood there, holding a six-pack of beer. His easy smile faltered, then collapsed entirely. His eyes dragged slowly down Mark’s body—the swollen tits barely contained in the stretched tank, the dramatically widened hips, the torn shorts showcasing the colossal ass. Charlie’s mouth opened, then shut. He wasn’t bored or businesslike. He was stunned.

“Mark? Jesus… fuck. What… what happened to you?”

Mark couldn’t speak. He hugged his arms across his chest, a futile gesture that only pushed his breasts together, accentuating their cleavage.

Charlie stepped inside, closing the door behind him. He kept staring, a flush creeping up his neck. “They said you needed… company. They didn’t say you’d look like… this.” There was no disgust in his voice. Just a thick, mounting fascination. He put the beer on the table, his eyes never leaving Mark’s body. “Are you… are you okay?”

The feigned concern was a thinner veneer than Charlie thought. Mark saw the way his eyes kept snagging on the tight fabric over his nipples. The chemical cocktail in Mark’s blood, the nutrient drink, hummed in response to the attention. A treacherous warmth bloomed in his lower stomach, distinct from the cramps.

“I’m… in the program,” Mark whispered, his voice soft, yielding.

“Yeah. No shit.” Charlie took a step closer. He reached out, not roughly, but with a hesitant curiosity. His fingertips brushed the side of Mark’s breast where it swelled out from the arm of the tank top. Mark flinched, but didn’t pull away. A sharp jolt of sensation—shame and a raw, physical thrill—raced through him. “Christ, they’re real,” Charlie breathed.

His touch grew bolder. He palmed the full weight of one breast through the fabric, his thumb circling the hardened nipple. Mark’s breath hitched. A pathetic, needy sound. His own body was betraying him, responding to the touch, the nipple pebbling tightly under Charlie’s thumb.

“You like that?” Charlie murmured, his earlier pretense of concern evaporating. “You look like you do.” He used his other hand to grab Mark’s hip, his fingers sinking into the new, pillowy fat. “Look at this. Fucking unreal.”

He pushed Mark backward toward the couch. Mark went, his legs weak. This wasn’t the brutal efficiency of the first man. This was slower, more inquisitive, more intimately degrading. Charlie didn’t shove him down. He guided him, his hands all over Mark’s new topography, mapping the changes with a greedy focus.

“Take this off,” Charlie said, tugging at the tank top.

Mark obeyed, raising his arms. The cool air hit his bare skin, his breasts swinging free, heavy and full with prominent, dark nipples. Charlie stared, his breath quickening. He didn’t speak. He just leaned in and put his mouth on one.

The shock was electric. Wet, hot suction. A flick of the tongue over the hypersensitive nub. Mark cried out, his back arching of its own volition, pushing his breast deeper into Charlie’s mouth. It wasn’t pleasure as he’d ever known it. It was a deep, cellular unlocking, a direct line to the confused core of him. His hands came up, not to push Charlie away, but to tremble in the air beside his head.

Charlie suckled like a man tasting something addictive, one hand mauling the other breast, pinching and pulling at the nipple. He switched sides, his mouth voracious. Mark was making sounds now, little gasping whimpers. The soreness was still there, but it was being transmuted, melted into this overwhelming sensory overload.

“On your hands and knees,” Charlie ordered, his voice thick. “Want to see the rest of the work.”

Mark moved clumsily, his large breasts hanging heavily, swaying as he got into position on the floor. He heard Charlie’s zipper, the rustle of jeans. A cold droplet landed on the small of his back.

Charlie didn’t enter him right away. He knelt behind him, his hands spreading Mark’s ass cheeks apart, thumbs digging into the soft, abundant flesh. “Fucking incredible,” he muttered. He rubbed the head of his cock against the tight, unused hole from the night before, still tender. Mark tensed, a spike of fear cutting through the chemical haze.

“Relax,” Charlie said, but it wasn’t gentle. It was a command. He spat, a wet glob that landed precisely on Mark’s entrance. He used his cock to smear it around, the friction dry and painful. “They said you’re built for this now. So take it.”

He pushed in. The stretch was agony, a tearing, burning breach. Mark screamed into the carpet, the fibers scratching his cheek. Charlie groaned, a sound of pure conquest, and sank in to the hilt in one relentless drive. He didn’t pause. He set a brutal, jackhammering pace, each thrust slamming Mark’s body forward, making his breasts swing violently and his new gut jiggle.

“That’s it, you fucking freak,” Charlie grunted, his hands anchoring on Mark’s widened hips, fingers leaving bruises in the soft fat. “Look at you. Look what they made you. A fucking bitch. A set of holes and tits.”

The words were like acid, but they fused with the physical violation, becoming part of the degrading stimulus. The pain began to blur again, edged with a dark, shameful glimmer of something else. His own cock, trapped beneath him, was hard, leaking onto the carpet. Each punishing drive forward rubbed it against the rough fabric, sending confusing sparks through his nerves. He was being torn apart from behind and stimulated from the front, his body a contested territory of pain and perverse reward.

Charlie leaned over him, his chest pressed against Mark’s sweaty back, his mouth near Mark’s ear. “You’re gonna cum,” he panted, his rhythm becoming erratic, brutal. “Aren’t you? You’re gonna cum like a girl while I fuck this fat ass. Do it.”

The command, the overwhelming bombardment of sensation, the drugs in his system—it created a perfect, horrifying storm. A convulsive shudder ripped through Mark. He came, untouched, a weak, dripping orgasm that felt less like pleasure and more like a systemic failure, a short-circuit of his old self. A thin, broken wail tore from his throat.

Feeling him spasm, Charlie let out a choked cry and drove in deep, pulsing inside him. He stayed there for a long moment, his weight crushing, before pulling out.

Silence, broken only by their ragged breathing. Charlie stood, tucking himself away. He looked down at Mark, collapsed on the floor, a mess of shaking limbs and exaggerated curves, cum and spit and sweat gleaming on his skin.

“Thanks for the beer, man,” Charlie said, his voice oddly normal now, edged with a faint, disgusted awe. He left without another look.

Mark lay there for an hour. The cramps returned, deeper. He crawled to the fridge and drank another bottle of the white liquid. The changes continued as he lay on the cool linoleum. His breasts felt fuller, heavier. His hips ached with a fresh, settling weight.

His phone buzzed. A single photo message, sent from an anonymous number. It was a picture of him, taken from behind during the act with Charlie, his monstrously enlarged ass in the air, his face contorted.
