Michael was looking after Janet.
She came in, wearing jeans and a tshirt.
Michael smiled at her, patting his lap.
Janet smiled and went over, climbing over his lap, her butt was quite plump.
Michael smirked and smacked her left cheek, making it wobble.
Janet giggled and wiggled her bubble butt, playfully kicking happily.
Michael altenated cheeks "Naughty girl!" He playfully scolded.
"I sure am!" She giggled, wiggling her giant butt for him.
He bared her butt, smacking harder.
She giggled louder the harder he spanked.
Michael stopped when her butt was glowing red and hugged her.
She hugged back, smiling at her brother.
He smiled back, rubbing her big butt.
