Chapter 3: Dick Nipples
The door to Brianna’s room clicked shut, sealing them in a private, perfumed universe. The air was close and warm, saturated with the scent of vanilla candle wax, old sweat, and something subtly chemical—rubbing alcohol, maybe, or the ghost of a vape pen. A single candle guttered on a crammed nightstand, its flame throwing jumpy shadows across a landscape of rumpled silk sheets and discarded clothes.
Bree’s bed was a testament to her dual nature. Textbooks on organic chemistry were stacked neatly on the floor beside it, while the headboard itself was a diary of passion: deep, frantic scratches marred the dark wood.
“Control,” Ronnie snorted, tossing Mae onto the bed. She landed in a valley between two pillows, the silk cool against her underside. “Your idea of ‘controlled’ is a mess, Bree.”
“Variables can be messy.” Bree was already shedding her tank top, her movements deliberate. The candlelight lapped at the new, staggering weight of her breasts. They hung lower now, the undersweep a heavy, full curve that brushed the top of her shorts. Her nipples, the transformed grapes, were darker and more pronounced than ever. She climbed onto the bed, the mattress groaning in protest, and loomed over Mae. Her eyes, magnified behind her glasses, were pools of reflected flame. “We need to isolate the mechanism. Topical application versus… internal.”
Ronnie kicked off her sweats and joined her, the bed dipping violently. “You’re thinking too hard. It just works.” She picked Mae up, her grip familiar and proprietary. “What do you want to try?”
Bree lay back against the pillows, her massive breasts spilling to either side of her ribcage. She took one heavy mound in each hand, lifting them, presenting the stiff, dark nipples. “Here. Direct contact. During arousal. We need to see if the effect is localized by the cum, or if it’s catalyzed by the, uh, the user’s… peak.”
Ronnie’s laugh was a warm puff of air. “You want me to make you come using this thing on your tits.”
“For science,” Bree said, her voice already losing its clinical edge, turning breathy.
Mae wanted to dissolve. To shatter. This was a new circle of hell: being used as a tool on the very body parts that had been the secret focus of her own deepest, most forbidden longings. The irony was a barbed wire knot in her silent core.
Ronnie didn’t need further instruction. She knelt beside Bree, her own impressive chest hovering. She guided Mae’s slick, pliable tip to Bree’s right nipple. She didn’t just rub. She encircled it, applying pressure, mimicking a motion that was utterly foreign and devastatingly effective.
Bree gasped, her back arching off the sheets. “Oh, God. Yes. Like that.”
The sensation for Mae was indirect but electrifying. The texture of Bree’s nipple—hard, pebbled, yet velvet-soft—pressed against her most sensitive surface. And she could feel Bree’s arousal radiating like a furnace. The chemistry PhD’s breath hitched, her hips making small, involuntary circles on the bed. The secret hedonist was fully in charge now, the scientist a distant observer.
Ronnie worked with a focused intensity, switching between nipples, using Mae’s foreskin to tease and pull. “Gonna come just from this, Bree?” she taunted, her own excitement palpable. “That’s kinda hot.”
Bree couldn’t answer. Her hands fisted in the sheets, knuckles white. Her mouth was open in a silent ‘O’. The low, wet sounds in the room weren’t just from Mae’s surface; Bree was soaking through her shorts. The smell of her, musky and sweet, mixed with the vanilla and the faint, strange odor of Mae’s own secretion.
Mae felt the impossible pressure building again. This time, it was tied to Bree’s climbing frenzy, to Ronnie’s voyeuristic thrill. She was a reactor, and their pleasure was the fuel.
“Now,” Bree choked out, her body seizing. “Now, Ronnie, now!”
As Bree’s climax ripped through her, a shuddering, back-breaking wave, Ronnie pressed Mae’s tip hard against the left nipple, holding it there.
The release was instantaneous.
A hot, thick jet erupted from Mae directly onto the taut, dark nub. Then another, coating the right one. It wasn’t a spill or a trickle. It was a targeted eruption.
Bree cried out, a raw, ragged sound. The transformation wasn’t a slow swelling. It was a reconfiguration.
The grape-sized nipples didn’t just grow. They changed. They elongated, thickening into solid, cylindrical shafts of flesh, pushing out from the areolae. They gained definition: a distinct glans formed at each tip, crowned, and a ring of softer, movable flesh—a tiny foreskin—gathered at the base. In the flickering light, they were unmistakable. Two small, perfect, erect penises, each about two inches long, jutting from the mounds of her breasts.
The shuddering of Bree’s orgasm subsided into a profound, trembling stillness. Ronnie stared, her mouth slightly agape, the joke gone from her eyes, replaced by pure awe.
Breathing hard, Bree slowly pushed herself up on her elbows. She looked down at her chest. Her hands, trembling, came up. She didn’t touch the new structures at first. She just stared.
Then, with the reverence of a explorer discovering a new continent, she wrapped her fingers around the left one. She gave an experimental stroke. The miniature shaft hardened further in her grip.
A soft, wondering sigh escaped her. “Oh,” she whispered.
She looked at Ronnie, then back at her chest. A slow, dazed smile spread across her face, erasing any last trace of the academic. This was beyond her wildest, most secret fantasies.
“They’re perfect,” she breathed.
Holding Ronnie’s gaze, Bree guided the newly-formed nipple to her own mouth. Her lips parted. She took the tip, the glans, inside. She closed her eyes and suckled, a deep, hungry pull. Her other hand stayed on the opposite breast, stroking the other shaft in a steady, rhythmic pace.
Ronnie watched, her own hand drifting between her legs, her expression one of stunned hunger. “Fuck, Bree.”
Bree moaned around her own flesh, the vibration traveling through the sensitive structure. The obscene, intimate sound filled the room, drowning out the spit of the candle.
After a moment, she released it with a soft pop. She was panting, her glasses fogged. She looked down again, then at Mae, still clutched in Ronnie’s forgotten hand.
“The variable isn’t the cum,” Bree said, her voice husky with revelation and desire. “Or not just the cum. It’s the intent. The… the want. I wanted them bigger. Different.” She licked her lips, tasting herself. “It gave me exactly what I wanted.”
She reached out and took Mae from Ronnie’s limp grip. She held the dildo up, turning it in the shaky light, studying its contours as if for the first time.
“We’ve been thinking too small,” Bree murmured, her thumb rubbing over Mae’s tip. A dark, thrilling calculation shone in her eyes. “If it responds to desire… then we just need to be more specific.”
She looked at Ronnie, then at the scratches on the headboard, a plan solidifying in the heat of her new, unimaginable body. The study session was over. The experiment had entered a new, uncharted phase. Bree wants to fuck Ronnie with her nipple dicks. Bree wants Ronnie to have the longest, saggiest tits and a huge pussy.
