REVERSAL
by the Crimson Kid
Heinrich Beltran felt relief as Emma strode towards their newly-rejuved daughters' bedroom, lexanite bath brush in hand—for once he wasn't the target of his wife's annoyance.
Punishment was already occurring as Sophia, the dark-haired nude Voluntaras, had her taller blonde sister Marta lying across her chubby thighs and undergoing a solid handspanking. Marta's nightgown was above waist level, leaving her firmly-rounded posterior exposed to her sister's steadily –slapping palm.
"Stop that right now!" Emma's voice reflected exasperation as she stormed into the room.
Sophia delivered two more crisp spanks. "Marta's a tattletale, she deserves this punishment."
"That's my decision," her mother said curtly, pulling Marta awkwardly to her feet. "Only I administer discipline in this household." She addressed her sniffling, pink-bottomed Voluntaras daughter. "Sophia went to bed butt–naked, right?"
The larger twelve-year-old nodded. "Yes, Mom."
Emma frowned. "So you threatened to tell and she spanked you for tattling...?"
"Planning to anyway," Sophia interjected.
"You'll each be chastised for the spanking, since Marta clearly cooperated. Nudity's a separate offense, Sophia... But that doesn't justify your tattletale intentions, Marta." Emma sighed. "Don't think I missed seeing you both grinding your groins together either."
"What's the point of having these young bodies if we can't play a little?" Marta demanded petulantly.
"I should be naked in bed if I want," Sophia pouted.
It was difficult for the girls to adjust to the limitations of being adolescents under parental authority after being a Lesbian married couple for thirty-five years, their mother knew. She'd considered allowing Sophia to practice her clothing-free Naturalism while sleeping, but that could be an invitation to sisterly sexual activity.
"There's only one bare part of you that I'm concerned with," Emma countered, sitting down on Sophia's bed, "Bend it over my knee immediately!"
Once the nude rejuve was in position, she was thoroughly walloped by the polyplast brush's flat back. The girl quickly was blubbering while squirming across Emma's thighs, but the paddling continued until the preteen's plump rump was shining scarlet.
"Into the corner, nose touching," her mother instructed. "Marta, take your sister's place here." She patted her lap.
"Yes, ma'am." The blonde reluctantly complied, then her nightie was rucked forward and she was spanked as soundly as Sophia had been, leaving her trim southern hemispheres glowing a deep magenta. Bawling shamelessly, she went to another corner to display her exposed posterior, nightgown held up.
Emma addressed both of her new daughters before exiting. "No sex, no gratuitous nudity and no spanking except by me—those household rules will be followed!"
Heinrich entered the bedroom of the females who had been his parents during his Penitatas and Completatas days. Although they had loved him dearly then, they'd both frequently blistered his naked hindquarters —so he was ironically appreciating their red-bottomed display.
"Enjoying yourself, Heinie?" Emma's question startled him. "Looking at the girls' derrieres, that's another household rule broken... Your turn over my knee."
Two minutes later, the spanking brush was plastering Heinrich's thong-separated bare buttcheeks as his daughters watched.
Sophia giggled. "Welcome to the club, Daddy..."
