Kinktober 23 - Competition
Noelle always believed the sibling rivalry between herself and her sister was all on her sister. Natasha had never shown any interest in babies before she got married but now acted like she was the first woman to ever get pregnant. Her socials were insufferably cliche for the past year, and she even had one of those shirts that said, “I make new people. What’s your superpower?” Despite being completely flat, Natasha was tall and pretty and had a husband and a newborn. All of that wouldn’t matter, except she was constantly criticizing Noelle and her life choices.
Natasha had come to their parent’s house to show off Baby Ava to her mom while her husband was out of town for work. It was bad enough that Noelle had to spend the summer with her parents, but now her big sister was here to offer more of her unsolicited advice, no doubt.
Noelle knew she should go downstairs, but she was stalling. Her dread of being interrogated by her sister was almost stronger than her desperate need to hold her niece, Baby Ava. Sitting cross-legged on the floor, Noelle stared at the idol of Titania and wished she could burn incense without her mom or sister thinking she was smoking pot.
Then, the sound of Ava’s fussing increased into a full wail. Her mom had told her all about Natasha’s struggles with breastfeeding, and it sounded like the infant was also uninterested in the artificial formula she was forced to drink.
As the sound of her crying niece hit her ears, Noelle felt a tingling in her chest. It started at her ribs and spread out to her nipples. Lightly scratching through her black tank top, Noelle felt a little more jiggle than she was used to. She glanced down and saw more pale cleavage than she expected but brushed it off as her cycle coming a little early. She decided it was time to go downstairs. After finding confidence in her body, Noelle was certain that her sister was jealous, even if Natasha refused to admit it.
Halfway down the stairs, Noelle saw her sister on the couch trying to bottle-feed her daughter. “Mom didn’t tell me you were coming over!”
Noelle felt her boobs bouncing as she descended the stairs and wished she’d put on a bra. The tingling grew more intense the closer she got to the wailing infant, but it would be too weird for her to run back up to her room now.
As she walked over to her sister and niece, Noelle felt a hint of satisfaction at the way her sister’s eyes widened. Natasha was always criticizing her wardrobe, saying stupid shit about how she could get any guy she wanted if she dressed nicer. The tight tank top showing off her tits was clearly doing its job—making Natasha’s “advice” backfire.
Noelle spoke sweetly to the baby, “What’sa matter, sweet girl?”
“What happened to you‽” Natasha snapped, making Ava’s wailing increase.
Noelle shushed her sister, “Don’t yell. What do you mean?”
“You’re… you’re huge!”
Natasha pointed to Noelle’s chest, and she looked down. This was way more than her monthly bloating.
“Huh, weird. I thought I felt something when I heard Ava crying…”
Noelle shrugged and held out her hands to the infant. Stunned speechless, Natasha lifted Ava into Noelle’s arms. Noelle drew the baby to her chest, resting her head on her shoulder and rocking side-to-side, making soothing noises. Ava continued to wail, and the tingling in Noelle’s chest grew into a rumble.
“Noelle…”
“What?”
“They’re getting even bigger!”
Noelle craned her neck to look around the baby and saw the round bulges of her breasts. They were nearly twice as big as normal, and as she watched, her tank top slid further down as her flesh slowly rose out of it like rising bread dough. Ava’s tiny hands clutched at her chest, and Noelle sat on the adjacent couch, lowering the baby to her lap.
She felt something warm near her nipples a moment before her sister said, “Are you… leaking‽”
Noelle touched her shirt, and her fingers came away wet.
“Give her to me,” Natasha said.
Ava’s hands were still reaching for Noelle’s chest, and her body seemed to flood with maternal instinct. Wordlessly, she slipped the hem of her tight shirt above one breast. Bloated and full, the lobe had grown bigger than her head. It dwarfed the newborn as she carefully lowered the nipple toward her mouth.
Natasha’s voice was a whisper. “What are you…?”
The baby latched onto Noelle’s nipple almost instantly, and a warm rush of satisfaction rolled over Noelle. Natasha rolled her head back against the couch. “Fuck you, Noelle.”
Noelle’s world was consumed by the small life in her arms. Ava made soft suckling and gulping sounds as she drew nourishment from Noelle’s body. Cradling Ava’s head in the crook of her elbow, she stroked the baby’s hair.

Titania took in a deep breath as her breastplate grew loose enough for her to breathe.
“There, child,” Hera said, patting the blonde goddess on the shoulder, “Doesn’t that feel better?”
“Yes, thank you.”
“It’s better to let the blessing flow back out of you—instead of holding it all for yourself.”
