Borealis' Gender Problem

You were officially part of Borealis' Family; The Nakashima Family, Where you live in the Nakashima Mansion where the Family Members are: Aurora Nakashima, Irenee Nakashima, Bliss Nakashima, and Borealis Nakashima himself, Which later will become Borealina Nakashima after his gender will be switched from the 3rd paragraph, Including you as their special member.

At the mansion of Nakashimas, Aurora was sitting in the living room, where her Lavender-colored Fox tail sways while she plays on the TV with PS4 Controller while she was waiting for Borealis to come out, While Irenee is Fixing Bliss' systems from maintaining errors, However, Borealis, who was sleeping in his room despite last night of his Overnight Working duty that he drank the Apple juice without him knowing there was a magic made of Genderswap, and finally, You, awake and playing games on your phone.

The first rays of morning sunlight pierced the gauzy curtains of Borealis Nakashima’s bedroom, casting golden streaks across the cluttered floor—strewn with old books, half-finished enchantment diagrams, and crumpled pajama pants. The alarm clock buzzed faintly beside her bed, but it wasn’t the noise that stirred her—it was a strange, unfamiliar weight upon her chest, Not knowing that her male form before, has turned into her female form just yet.

With a groggy sigh, Borealis groaned and stretched under her blanket. She rubbed her eyes, sat up slowly, and scratched her head, her tousled long hair falling into his eyes.

“Ugh… another weird dream…” she mumbled, voice still gravelly from sleep.

Swinging her legs over the edge of the bed, she stood up—only to pause. There it was. That odd sensation. Something was off. Her center of balance had shifted, subtly, but unmistakably. She took a step.

Jiggle, Another, Jiggle—sway—bounce.

She blinked. Her hips moved differently. Her thighs brushed together in a way they never had before. Her pajama shirt hung tighter around the chest than he remembered. She frowned. Confused, she shuffled toward the bathroom, scratching absently at the hem of her shirt where it clung unusually close to her body.

Entering the bathroom, she reached for her toothbrush. As she leaned over the sink, she lifted her head toward the mirror—And froze.

There, staring back at her, was not the boy who had gone to sleep the night before—but a stunning young woman with shimmering silver-blue hair tousled by sleep, wide violet eyes full of confusion.

“W-what the—?!” She stumbled back.

“WHAT IN THE SEVEN STARS OF NAKASHIMA!?” she screamed.

Her hands flew to her chest. Soft. Full. Too full. He looked down—massive breasts strained against her shirt, and beneath that, a cinched waist leading into wide, curvaceous hips that swayed with every panicked move. She turned, caught a glimpse of her reflection from behind—and gawked at the firm, round shape of a feminine backside she had most certainly not possessed the night before.

“Oh no no no—what is THIS?! I—I’m a girl!?”

The toothbrush clattered to the floor. The sound echoed as she slumped against the wall, face flushed, chest heaving—not from fear of monsters or curses, but from the sheer, mind-bending realization that Borealis Nakashima had awoken not as a boy—but as a voluptuous young woman, Which made him find out that he turned into a girl.

Meanwhile, You heard the scream, You turned your phone off and decided to rush to Borealis' Master bedroom, panicked and worried to check what happened to Borealis, When you go inside, You enter into her bathroom, And suddenly, You met her, Borealis, who was once a man, suddenly turned into a girl, Who had a Large, Perky Breasts, Permanently hard nipples, Big hips, with Plump plush rear, Along with Wolf ears, wolf tail, As well as her clothes changed too, Which her name, Borealis, finally switched into Borealina.
