Rob & Amanda

Back at the house, Amanda and Rob were still in bed when the latest changes hit.

Amanda felt a warm, tingling fullness bloom in her chest. Her already impressive MILF breasts swelled larger, becoming heavy and full. A few moments later, a gentle leak started — sweet, warm milk beading at her nipples. The Milky & Productive change had taken hold perfectly. She cupped one heavy breast, giving it a light squeeze. A thin stream of milk sprayed out, landing on Rob’s skin.

“Mmm… look at that,” Amanda purred, her Flirty Tease personality making her voice low and seductive. “Mommy’s making milk for her good little girl.”

Rob’s eyes widened as her own chest transformed. The Massive Watermelons change turned her small, perky breasts into enormous, heavy, perfectly round orbs that dominated her tiny frame. They were so large on her petite body that they looked almost cartoonish — soft, heavy, and incredibly sensitive. The weight pulled her forward slightly, and every small movement made them sway and bounce dramatically.

“Oh… they’re so big,” Rob whispered in her airheaded, girly voice. She tried to cup them but her small hands couldn’t contain the massive flesh. “Mommy… they feel really heavy…”

Amanda’s eyes darkened with lust and dominance. She shifted so she was straddling Rob’s waist, her own leaking breasts hanging above the smaller girl’s face.

“That’s right, baby. You used to be my dad… the big, strong man of the house. Now look at you.” Amanda leaned down, dragging one leaking nipple across Rob’s lips. “Just a tiny little sister with huge tits. Open up for Mommy.”

Rob obeyed instantly, the Obedient Girl compulsion making resistance impossible — and the act of obeying felt so good. She latched onto Amanda’s nipple and began to suckle. Sweet milk flowed into her mouth as Amanda moaned in pleasure.

“Good girl,” Amanda cooed, stroking Rob’s hair while gently grinding against her. “Drink Mommy’s milk. These big, heavy tits of yours are going to look so cute when you’re bouncing on top of me later.”

Rob whimpered around the nipple, suckling eagerly. Her massive new breasts squished against Amanda’s body, the weight and sensitivity making her squirm with every movement. Milk continued to leak from Amanda’s chest, dripping down onto Rob’s enormous chest and making a mess of both of them.

Amanda pulled back just enough to look down at her. “You love this, don’t you? Being Mommy’s obedient, big-titted little toy.”

“Yes, Mommy,” Rob gasped, milk dribbling down her chin. “I love it… I love being your good girl…”

Amanda smiled, dominant and satisfied, as she leaned down to kiss Rob deeply, their heavy, milk-slick breasts pressing together.

The old father-daughter relationship felt like a distant dream now. This — Mommy feeding and dominating her eager little sister — felt completely natural.
