Chapter 4: A New Plaything
The silence in the room was a held breath, broken only by the soft, strained creak of the bed’s frame and the wet sound of Bree’s mouth on her own new flesh. The flickering lamp painted everything in strokes of amber and deep shadow.
Ronnie watched, her hand still between her own thighs, her expression a war between arousal and a dawning, competitive edge. “You look ridiculous,” she said, but her voice lacked its usual force. It was husky.
Bree released her nipple with a final, lingering lick. “I feel incredible.” She looked at Ronnie, her eyes sharp behind her glasses. “Your turn. But we need parameters. Control.”
“Control my ass,” Ronnie snorted, pushing herself up. “Just gimme the thing.”
“No.” Bree’s voice was calm, final. She set Mae down on the rumpled silk and slid off the bed. She went to her closet, rummaging, and emerged with two long, soft scarves, the color of deep wine. “We’re testing a hypothesis. If the… effect… is tied to the subject’s own climax, or if it can be directed. Imposed.”
Ronnie’s eyes narrowed. “What are you doing with those?”
“Ensuring you don’t interfere.” Bree’s smile was small, almost clinical. “Lie back.”
A flash of rebellion crossed Ronnie’s face, but it was chased by a hotter, darker curiosity. The sight of Bree’s transformation had lit a fuse in her. She wanted that shocking, impossible change for herself. She lay back, her head near the scarred headboard. “This is weird, Bree.”
“All breakthroughs are,” Bree murmured, taking Ronnie’s wrist.
The tying was not rough, but it was thorough. Bree used a practiced, efficient knot, looping each scarf around a wrist and then securing it to the sturdy bedposts. She pulled them snug, not enough to hurt, but enough to eliminate any doubt. Ronnie was anchored, her arms spread, her powerful body displayed. The lamp light poured over the landscape of her: the impressive swell of her breasts, the dark coins of her nipples, the tight plane of her abdomen.
Mae, lying discarded on the sheet, had a perfect, horrifying view. This was Ronnie, the domineering queen of the house, trussed up and vulnerable. A thrum of conflicting sensations pulsed through Mae’s inert form—a twist of horror, a thread of vengeful satisfaction, and beneath it all, the relentless, shameful pull of her own deepest fixations made flesh.
Bree stepped back, critically examining her handiwork. “Good.” She crawled onto the bed, settling between Ronnie’s spread legs. She stared at Ronnie’s pussy, then up at her face. “Tell me what you want. Exactly.”
Ronnie tensed, pulling slightly at the scarves. “I want you to untie me and stop being a freak.”
“Be specific,” Bree said, her finger tracing a slow, wet line through Ronnie’s folds. Ronnie jumped, a gasp catching in her throat. “About the change. You liked your nipples getting bigger. What else? Do you want them longer? Heavier?”
Ronnie’s defiance cracked. Her hips gave a tiny, involuntary jerk. “Yeah,” she breathed. “Heavier. I want to feel them pull.”
“And here?” Bree pressed two fingers inside, slowly. “You’re already so pretty. Do you want to be… more?”
A shudder racked Ronnie’s body. Her head tipped back, thumping against the headboard. “I don’t know. Just… make it feel good. Make it more.”
“Not specific enough.” Bree withdrew her fingers. She reached for Mae. The familiar grip was a cage. Bree brought Mae’s tip to her own mouth, coating it generously with saliva, her eyes locked on Ronnie’s. “I’ll be specific for you.”
She positioned Mae at Ronnie’s entrance. Without ceremony, she pushed, sliding the entire length in with one smooth, deep stroke.
Ronnie cried out, back arching off the bed, the scarves tightening. “Fuck!”
Bree began to move. Not with frantic passion, but with the steady, measured rhythm of a scientist titrating a solution. Out. Slow. Deep. Each withdrawal was almost complete; each thrust a full, deliberate penetration.
“You’re going to feel a stretch,” Bree whispered, watching Ronnie’s face. “A deep, filling stretch. And then a release. A transformation. Your tits are going to grow, Ronnie. They’re going to get so heavy. They’ll hang past your navel. They’ll sway when you walk. Your nipples will darken. They’ll thicken. You’ll feel their weight every second.”
As she spoke, she fucked Ronnie with that relentless pace. And with every push, the pressure built in Mae’s core. It was different now. It wasn’t tied to her own pleasure, but to Bree’s intent, to the vivid, commanding words painting a picture in the humid air.
Ronnie was losing herself. Her protests had melted into a stream of ragged moans. Her eyes were glazed, fixed on Bree’s face, drinking in the promises. “Yes,” she slurred. “Yeah, make ’em heavy.”
The first hot jet hit deep inside Ronnie just as Bree reached down and pinched a nipple, hard.
Ronnie screamed. It was a sound of shock and overwhelming sensation. Her body convulsed against its restraints.
Mae felt the change through their connection. A loosening, a profound softening and then a rapid, cellular expansion. Ronnie’s breasts, already full, began to swell. They didn't just grow rounder; they elongated, the tissue becoming denser, heavier. They spilled over the sides of her ribcage, the downward pull visible. The areolae widened, darkening to a deep burgundy. The nipples themselves bulged, thickening into blunt, thumb-sized pillars.
Bree didn’t stop. She kept pumping, the wet, rhythmic sound filling the room. Another surge, another internal eruption.
Ronnie’s body jolted. The growth continued. Her breasts slid further, their weight now a tangible force, dragging them toward her sides. They passed the halfway point of her torso. The new, heavy undersides brushed the sheets. Her nipples, now the size of small plums, looked painfully hard.
“More,” Bree chanted, her own breath coming in sharp pants. She was no longer a detached observer; she was a sculptor, consumed by her work. “Your pussy. Your lips are getting fat. Puffy. Like a perfect, swollen heart. Your clit… it’s pushing out. Growing. A thick little cock, just for me.”
Each word was a command that Mae’s power obeyed. As the next pulse flooded into Ronnie, the changes manifested. Ronnie’s outer lips plumped, becoming lush and pronounced. And higher up, her clit engorged, straining outward, lengthening and thickening into a distinct, fleshy protrusion that stood proud from its hood.
Ronnie was sobbing now, tears cutting tracks through her sweat. But they weren’t tears of pain. Her hips were churning, meeting every thrust, her body embracing the violation of its very form. “Bree… God… it’s too much…”
“It’s exactly enough,” Bree corrected, her rhythm finally beginning to falter, her own control fraying. She was close, watching her creation unfold. Ronnie’s breasts were monumental, swaying heavily with each movement, their nipples now dark, textured nubs. The transformation was a done thing. Ronnie was someone else. Something else.
With a final, guttural cry, Bree drove Mae in to the hilt and held it there as her own climax took her. The corresponding release from Mae was volcanic, a scalding flood that seemed to seal the changes in place.
For a long moment, the only sounds were their ragged breathing and the faint, dripping wetness.
Bree collapsed forward, her face landing between Ronnie’s colossal new breasts. She nuzzled the heavy, warm flesh, then turned her head and took one of the grotesquely enlarged nipples into her mouth, suckling softly.
Ronnie whimpered, a broken, submissive sound.
After a moment, Bree lifted her head. She looked at Ronnie’s glazed, tear-streaked face, then down the length of her utterly transformed body—the vast, sagging breasts, the swollen sex, the thick, new clit. She smiled, a thing of pure, possessive delight.
She leaned close, her lips brushing Ronnie’s ear. Her whisper was a vow that curled like smoke in the lamplight.
“You’re going to be my perfect, saggy fucktoy.”
She pulled Mae free with a slick, obscene pop and rolled onto her back, holding the dildo up again, studying its glistening surface. Her other hand drifted to her own chest, stroking one of her small, erectile nipples.
Ronnie lay bound, her new weight a profound, settling reality on the bed. She tested the scarves once, weakly, then let her head fall back. A slow, overwhelmed tear rolled from the corner of her eye, tracing a path into her hairline. She wasn’t looking at Bree anymore. She was staring at the cracks in the headboard, her expression one of shattered, awestruck surrender.
Bree ignored her. Her gaze was fixed on Mae. The tool. The catalyst.
“So much left to test,” she murmured to herself, a world of terrifying possibility glowing in her eyes.
