Saturn stood ready, trying to ignore how ridiculous Sailor Venus looked in that stupid kangaroo costume.
"Hiya Satsy!" Venus said, giggling and waving. "You look all grumpyguts!"
"Venus – sorry about this," Saturn began. "I know you're in there-"
"Of course I am!" Venus giggled. "Why wouldn't I be in here? Where would I be?"
Saturn blinked.
"Anyway!" Venus continued, and hopped forwards. "Don'tcha wanna bippety-boppety-boo?"
Saturn frowned. "What did you just-"
Venus jumped forwards again, volleying a few light punches into Saturn's arm. "Hee! Bippety, boppety, boo! Just like that!"
Saturn retaliated, and Venus hopped easily out of the way of her clumsy blows. "You're not gonna win like that! You've really got to bip it your all!"
The Senshi of the sixth planet tried to work out what that meant, and then shook her head. "Okay, Venus – stop it!"
She raised her Silence Glaive. "Silence Wall!"
Venus continued talking, but the shield effect meant that at least Saturn couldn't hear what her motor-mouth was saying.
Saturn glanced back towards the bench. "Girls? Any advice here?"
Pluto shrugged. "Sorry, no idea."
Uranus likewise drew a blank, shrugging. "Maybe you should try a really powerful attack?"
"Good idea." Saturn turned back to the fight, where Venus was still jabbering away behind the silence wall, and raised her weapon. "This is my ultimate attack," she said solemnly.
Energy grew around her glaive.
"Silence Glaive-"
Venus bounded forwards, through the Silence Wall, and snatched the weapon away. "Surprise!" she giggled, as the shield collapsed, and tucked the glaive away in her pouch before Saturn could react.
Then she regarded Saturn. "Someone's been naughty!" she said cheerfully. "It's a boxing match! Sharp pointy things not allowed!"
"What?" Saturn asked, flabbergasted. "Did you – but – just-"
Venus picked up Saturn, laid her on her lap, and flipped her over so she was facing downwards. "Naughty girls need to be taught a lesson!"
She wound up for a moment, just long enough for Saturn to start to work out what was going on, and brought her gloved palm down on Saturn's padded rear.
Saturn yelped with sudden pain, but mainly from sheer startlement.
"Naughty girls get spankings!" Venus explained, spanking away at Saturn's diapered rump. "And you were naughty, so you get a spanking!"
Saturn blushed, trying to wriggle out of Venus' grip.
She felt... really embarrassed. Like she'd been caught doing something she shouldn't, as well as the additional embarrassment from being spanked by her costumed friend while wearing a diaper.
She also felt almost lost in the big lap of the poofy-suited Venus, making her feel little in a whole different way.
Her struggles availed her nothing, and she endured twenty or thirty stinging swats and several more comments on how naughty she was before the spanking stopped.
"Now, have we learned our lesson?" Venus asked, and giggled.
"Give me back the Glaive!" Saturn demanded. Unbidden, one of her hands reached back to rub her spanked rump.
