Leon swished the flogger through the air, making Jean jerk against her bonds.  When he gently brushed it along her back, she twitched even more.

“Before we start in earnest,” said Leon in a conversational tone, “You need to change for me.  Robin, I expect you to keep her bound as she shifts.  Be creative.”

“What?” asked Jean, confused.

“Just a little change, at first.  Make your skin slightly purple.”  Leon watched, flogger swinging idly in one hand, making soft swishy noises.  Once the change was done the flogger fell against Jean’s back, making her yelp in surprise.

The yelp was followed by a soft moan, then “Ohhh... more!”

Leon chuckled deeply.  “Oh, there will be more.  But to get more, you need to give me more.  You know what I want, hippo-girl.  We’re going to play a game.  Every blow is an order, and that order is ‘change’.  We’ll measure progress by your girth, by how much of a hippo you become.”

“Seriously?”

The flogger fell against her back again, with a louder thwap.  Jean moaned and squirmed.  “I’m sorry sir.  Yes sir.  Becoming more... hippo-y.”  Jean closed her eyes and her bottom swelled.

“Excellent work, pet.  You’ve earned another.”   The flogger fell once more, harder.  Jean’s moan was louder, and a hint of a tail formed.  The blows came faster, and Jean’s body continued to change.  One blow and moan grew her ass, the next her breasts.  Another saw her add six inches of height, Robin scrambling and shuffling to keep up.  Her moans became louder and deeper as her throat elongated and thickened.

Leon adjusted his posture to deal with his target’s changing size and shape.  He realized his mistake as the flogger fell, too late to correct his aim.  Some of the flails missed Jean’s shoulder, cracking like whips against her neck.  She screeched in true pain, and lost her focus.  All the lovely hipponess went away.

Leon permitted himself one very soft sigh, then leaned down to kiss where the flails had landed.  There was no sign of redness there, or on Jean’s back.  “All better?”

Jean nodded.  “I’m sorry, Master.  It won’t happen again.”

“Indeed it won’t.  We begin again.  You were doing so well, my lovely hippo-girl.”  The flogger smacked down on Jean’s unaltered flesh.

Jean gasped and moaned, her skin darkening and thickening.  Another blow, then, and her bum started to swell.  “Thank you Master.”

Leon paced himself.  He’d studied the idea of flogging after spanking had proved so popular, and had some idea what he was doing... but he’d never held a flogger before and he didn’t want to tire too quickly.  It was difficult, for with each blow, each gasp and moan, Jean became more lovely in his sight.

Leon had lost count of the blows.  There had been enough to work from Jean’s enormous rump all the way to her rounded shoulders and back down to her ropy tail.  She was immense, taking up the entirety of the king-sized bed even spread-eagled, and Robin was struggling to contain her.  Her face had only the slightest hint of humanity to it, mostly around the eyes.  The rest was a rounded muzzle, from which guttural whines and squeaks emerged.

Leon let the flogger rest against Jean’s back, gently stroking up and down, the flails swishing against the hardened, leathery skin.  “Ah... perfection.  We’re done with changes.  Stay like this.”

Jean shuddered under the caress, skin twitching.  “Yes, Master.  Is it... over?”  Her low voice sounded disappointed.

“Beg.”

“Please, Master!  I need more flogging.  I was so close...”

“As you wish.”  The flogger fell against Jean’s backside with a loud thud.  

She shuddered and moaned, “More.  Harder.”

Leon’s eyebrow rose, and he did as he was bid, throwing more strength into the blow.  His reward was a louder moan.  

“Harder!”

Leon chuckled softly.  “To work, then.”  He varied the pace and strength of the blows, and every time he thought he’d pushed too hard, Jean pleaded for more.  Leon kept going until his arm was trembling and his hand was slick with sweat, and still she wanted more.  He took up the flogger in both hands, then, and did his best.  Her words failed her then, and her body writhed under the blows.  Suddenly, between one blow and the next her whole body went tense and stiff.

Leon held the next blow, leaning against the bed and panting as he watched her body vibrate with the tension.  A strange squeaky mewl emerged from her mouth, then suddenly the enormous hippo-girl slumped, looking as if she’d somehow deflated.  Her breathing came in ragged sobs.

Leon gestured Robin away, and gathered up Jean as best he could while her bindings slithered away.  “Shhh, Shhh.  It’s over.  You did it.”

Robin held up the flogger in two of her straps, canting her body as if to ask a question.  Leon nodded to her, and waved her toward the door.  He returned his attention to his wife, gently tugging at the ring.  “Let it go.”

Jean shook her head, closing her hooflike hand around the ring.  “N... no.  Wanna keep it ‘s long as I can.”

“But you’re in pain.”  Leon kissed the corner of one eye.  “I can see it.”

Jean wrapped her immenseness around Leon, cuddling him to her like a teddybear.  “Want it.”  She laughed, a low deep rumble in her chest.  “Shut the voices up.  Lets me focus.”

“On?”

“You, dummy.”  Jean kissed him with her enormous lips, covering half his face.  “You were incredible.  Thank you.”

Leon kissed her back, caressing her cheek with his open hand, too exhausted to do much more.  “I ran out of steam at the end.  Looked like you found what you needed even so.”

Jean sighed so happily it made Leon smile.  “Yeah.  I don’t know what that was but I soooo want it again.  My whole body was on fire.  Next time we’ll make you stronger, first.”

“Next time?” asked Leon.

Jean nodded emphatically.  “I’ll be your hippo-girl whenever you want if that’s what comes of it.  Though maybe not quite so big, hm?”

Leon grinned. “I might have gotten carried away watching you grow under the flogger.  God, you’re incredible.  If I had anything left at all, I’d make love to you until I couldn’t move.”

“I’ll hold you to that.  Another day.”  Jean sighed and stretched, then winced.  “Oog.  OK, ready to get rid of that now.”  She tugged on the ring, and it slipped out of her hoof.  Dropping the ring into Leon’s hands led to her body shrinking back to normal size, species and colour.  It also erased the striped bruises down her back.  “Do you still love me like this?”

“More than ever.”

Leon put the ring on, and let his body slip into Leona’s familiar form.  “Do you still love me like this?”

“I don’t care what you turn yourself into, I’ll love you just as much.”

Leona grinned.  “Even if I turned myself into a spider?”

“Sure,” said Jean with a laugh.  “I’ve got nothing against spiders.  And it’d keep Carrie-Lee from barging in.”

But as Leon’s limbs split and acquired a layer of black fuzz, Jean started looking less sure.  When an enormous spider towered over her, she eyed it critically.  “I know it’s you in there.  I’m n...not terrified, exactly, but I don’t find this remotely attractive.”

The spider’s head melted and reformed into Leon’s face.  “C’mon, give me a kiss...”

Jean laughed, and leaned in to kiss Leon softly.  “Remember what happens to spiders after sex.”

Leon shuddered, and his body smoothed back into human form.  “Right.  Pass on that.”

Jean pulled Leon in close.  “Mmm, much better,” she purred languidly.

Leon laughed softly, stroking a hand along Jean’s much reduced curves.  “Happy?”

“Better.  At peace.”

“Really?  No little voice spinning inside your head.”

Jean shook her head, grinning.  “Nope.  And all it took was you beating it out of me.”

Leon boggled at her, then started to laugh.  “I’m going to need to get a real flogger.”

Jean purred, and wrapped her arms around Leon.  “But not today.”

They laid content in each other’s arms until Jean fell asleep.  Leon carefully pulled up the covers so as not to wake her, then curled up protectively around her.

* * *

When morning arrived, Jean hopped lightly out of bed and snuck off to shower quietly.  When she was done, she kissed Leon and asked what he wanted for breakfast.

“Mmm.  Surprise me.”

Jean giggled.  “Give me the ring and I’ll give you a real surprise.”

Leon curled his fingers around it, and his body shifted to become a catgirl.  “Mine.”

“Stay like that, then.  Oooh, I have a fun idea.  Shrink to three inches tall, and I’ll make you a stack of pancakes taller than your head.”

Jean giggled as Leona shrunk into the bed covers.  The lump under the duvet got smaller and smaller until it was just a tiny wriggling bump.  She patted it softly.  “See you in the kitchen.”  The lump started making its way toward the edge of the bed, and she grinned.  “I should have the pancakes done by the time you make it.”

Jean was careful to watch where she put her feet while she worked.  Halfway through the second griddlefull of pancakes, a tiny catgirl form lept onto the kitchen island.  Leona waited until Jean was looking her way, and waved.

“Perfect timing, sweetie.”  Jean started piling pancakes onto a plate.  After the first five, she gestured to Leona.  “Hop up, so I can get the height right.”

Leona giggled almost imperceptibly, then stood on the plate beside the pancakes.  Five came up to her breasts, so Jean added the last three.  “There we go.  A stack of pancakes as tall as you are.”  She turned to flip the second batch of pancakes into a warming pan, then returned to see what Leona was up to.  She’d pulled a handful of pancake off the top one and was nibbling on it.

Jean leaned in close.  “How is it?”

“A bit dry,” squeaked Leona.  “Could use some syrup.”

“Of course!  I warmed some in the microwave, be right back.”  Jean gave the pitcher of syrup a swish around to make sure the syrup was evenly heated, and dripped a little on her wrist to make sure it wasn’t too hot.  Then she dumped it over the pancakes... and over Leona as well, drenching the kittygirl in syrup.

Leona giggled as the cascade of warm syrup pooled around her feet.  “That felt incredible.”  She dipped her handful of pancake in the syrup, ate it, and repeated the process.  Then she declared she was full.

“Now I’m all messy,” said Leona with a big grin.  “What are you going to do about it?”

“I could get a washcloth...” mused Jean, and saw Leona’s grin fade.  “Or I could clean you off the way mama cats do.”

Leona held her hands up in a ‘pick me up gesture’, and Jean grinned.  “Mama cat, it is.”  She scooped Leona up, and started licking her all over.  Leona giggled and sputtered and squirmed.  

When Jean pulled back, Leona grinned up at her devilishly.  “I still feel sticky.  You’re going to have to suck it off.”

“As my mistress wishes,” said Jean with a huge smile.  She leaned in close, tickled Leona’s feet with her tongue, then wrapped her lips around those tiny legs and started to suck.  

Leona squealed happily as she disappeared into that giant mouth up to her waist.  The huge lips bumped up against the cats-eye ring that she was wearing as a belt.  They parted, and an enormous tongue scooped the tiny catgirl into a cavernous mouth.  

When the darkness closed around her Leona started to wonder whether or not this had been a good idea.  Then the tongue started pressing and teasing, tossing her about and wrestling with her.  Leona hugged it tight with her arms and legs, riding it like a bucking bronco and laughing.

Leona felt her feet bump against the back of the massive throat, and squirmed to pull them away.  It didn’t help.  The cavern tilted, sliding her back toward her doom.  Leona grabbed on as tight as she could, squealing, “Don’t swallow!”  The giant tongue wriggled and pressed, tugging her backward, downward.  Leona could think of only one way to stop it.  She pressed her body more tightly against the tongue and melted into it.

Jean flung her mouth open when she felt her husband vanish.  “I was only teasing!  What did you do?”  She felt around inside her mouth, and her fingers brushed against the ring.  From the way it was embedded in her tongue, she realized what had just happened.  “Clever, honey.  Maybe I should keep you like this.”

She found a hand mirror, and peered into her mouth.  As far as she could tell, her tongue looked perfectly normal, other than the ring buried in it halfway back.  Still, she could feel Leona’s presence within it as a squirming warmth.  She picked up a ribbon and grinned.  “If you don’t change back right now, I’m going to keep you like this.”

When Leona didn’t emerge, Jean shrugged.  “Okay, then.”  She tied the ribbon around her neck, and stuck her tongue out at the mirror.  “You’re stuck as my tongue.  And I’m hungry...”

Jean sat at the table, and pulled Leon’s pancake stack to her.  She figured there was no point in wasting all that syrup.  Chewing and swallowing with the ring in the way required some practice, and a little delicacy.  She washed the ring off with a mouthful of warm water when she was done, swirling and twisting her tongue around as she did so.

“C’mon, Leona.  Enough’s enough.  Unless you want me to go kiss someone like this...  Staying as you are is a yes.”  Jean waited, then shrugged.  “I suppose it’s time to go put the others back to normal anyway.”

Jean found Robin with all her straps curled up tight around the sleek black flogger that had done such a number on her.  She petted the strap-girl softly.  “Hey.  You OK in there?”

Robin waggled a strap at her, but didn’t otherwise answer.  Jean pouted.  Nobody to kiss.  “C’mon, Leona.  Not funny any more.  I want my husband back.”

Robin wriggled free of the flogger and peered up at Jean curiously.  Jean stuck her tongue out and wiggled it before explaining.  Robin shook like she was laughing, then slithered straps up Jean’s body and started wrapping herself around Jean’s chest.

“Are you trying to embed yourself in me?” squeaked Jean as the pressure increased.  “Oh!”  As soon as she untied the ribbon from around her neck her chest absorbed the straps.  Her breasts swelled, then Robin’s face emerged from the right one.

“This is a familiar view,” Robin said with a laugh.  “Thanks, now we can talk.”

“Actually, what I wanted to do was kiss.”

Robin giggled.  “Might require a bit of flexibility to... woah!”  The breast she was occupying expanded and lengthened into a stubby tentacle, and her face was suddenly in front of Jean’s.

“I figure if kissing her sister doesn’t get Leona out of there, nothing will.”

Robin puckered her lips, then sighed when Jean didn’t follow through.  “Actually, it’s likely she can’t get out on her own.  You’re the one with the ring, now.  She’s just part of you, like I am.  I can’t get out either.”

Jean blinked.  “Oops.”  Then she giggled.  “I hope she had fun.  Maybe I should keep her...  Ah, but it’s her turn to run the show, and I want to see what she comes up with next.”

“Make your tongue longer,” said Robin.  “Then have Leona emerge.”

A tiny catgirl tumbled from Jean’s mouth, without the ring.  She started expanding even before she hit the bed, and soon Leon was back to normal.  “Well.  That was different.”

“Different good or different bad?” asked Jean, mumbling around the ring in her mouth.

“Different give me the ring and find out.”

Jean tugged the ring out of her mouth, and dropped it into Leon’s outstretched hand.  Her breasts shrunk back to normal and the mass of Robin-straps reappeared, swarming their way down her body to floor beside the bed.

Leon looked down at the straps where they were wriggling at his feet and sighed.  “It would be convenient if you could communicate.”  He set the ring on one of Robin’s straps, and said, “Grow your core to a human torso and head, but keep the straps as your limbs.”

Robin wriggled herself up to the bed once she’d finished changing.  “Oh, that’s so much better.  Thanks.”

Leon twisted a ribbon around one of Robin’s straps before reclaiming the ring.  “You’re welcome.  Thought you might like it, and going all the way back to normal wasn’t on the menu.”

Robin laughed, and held up the flogger in a pair of straps.  “So what are you going to do with her?”

Leon smiled broadly then, showing many teeth, and slipped the ring over one of the flails so Carrie-Lee could hear. He stroked the handle of the flogger reverently, and spoke directly to the ring.  “I’m not going to change you back.”

“Ever?” asked Robin weakly.

Leon’s grin managed to grow a little wider.  “Why should I?”

“But she’s a person!” protested Robin.  “You can’t just leave her like that.”

“Of course I can.  All I have to do is take off the ring and then the ribbon.  She’ll be an object, permanently.  Don’t worry, she’ll be well used.”

As Robin watched mutely, Leon plucked the ring and then ribbon off the flogger.  Leon handed it to his wife.  “Be a dear and put our new best toy on the bedside table.  We’ll be wanting it later.”

“You’re actually serious,” whispered Robin.  “How can you do this?”

“It’s easy,” said Leon.  “She sold off everything, broke all social connections to move to a new town.  Nobody will miss her.”

“I’ll miss her!” exclaimed Robin.  “Doesn’t that matter to you?”

Leon shrugged.  “Nobody’s going to miss you, either.”

Robin gasped in shock, straps thrashing.  “You...  Oh My God.  I’m in the same boat.  After the big fight with Mom, they’d believe I don’t want to see them.”

Leon chuckled wickedly.  “Exactly.  You make lovely bondage straps.  I’d hate to lose the use of them.”

Robin’s eyes narrowed in thought, then she smiled.  “You’re just winding me up.  You’re not actually into bondage.  May I borrow the ring?  I promise I won’t touch the flogger.”

“Under that condition, you may.”  Leon handed the ring over, and his sister turned toward her bedside table.

Robin’s digging turned up a large lump of clay.  She pressed the ring into it.

“What the heck is that?” asked Leon.

“I had some clay left over from my sculpting project,” said Robin over her shoulder.  Then she murmured to the clay, “Become a human.”

As it swelled and pinkened before Leon’s widening eyes, Robin grinned.  “She could feel it when I squished it, so I figured...  Hey sweetie.  How are you?”

Carrie-Lee laughed and hugged Robin, straps and all.  “Much better.  And... still a flogger?  Are you really going to keep it?”

Leon laughed heartily and honestly.  “Of course I am.  Especially now.  That version of Carrie-Lee really won’t be missed.”

Jean rushed into the room.  “CL?  But I put the flogger away!”

Carrie-Lee danced over to hug her friend.  “And I can still feel it.  This is awesome!  I wonder what it would feel like to be flogged by myself.”

“Probably a little confusing,” said Jean.  “Better have someone else do it.”

“Are you volunteering?”

“Ahem.”  Leon suddenly had three pairs of eyes on him.  “I believe it’s still my turn?”

“Something especially wicked, I hope?” asked Jean excitedly.  At Leon’s nod, she added, “I’ll go get the collars.”

With Jean out of the room, Leon turned to the others.  “Last chance to say no, Robin.”

“Don’t I get a say?” asked Carrie-Lee.  Leon shook his head, his grin growing.

Robin and Carrie-Lee conferred briefly, then Robin nodded.   “You’re sure about this?”

“Yep.”

She turned to her brother.  “We’re in.  Do your worst.”

“My worst, you say?”  Leon chuckled evilly.  “As the lady wishes.”

Jean returned with the collars, and Leon handed the black one to Carrie-Lee.  “Might want to sit on the bed before you put it on.”

Carrie-Lee did so, and Robin helped lay her out as the collar blanked her mind.  While she was distracted, Leon slipped the purple collar around her neck.  Robin turned to grin at him.  “Figured as much.  What’s the plan?”

Leon handed her the ring.  “You’re a catgirl with fluffy fur.”  He watched the change, then shook his head.  “No, no, not far enough.  Much more feline, especially around the muzzle.  Smaller breasts, but six of them.”

Robin giggled.  “Oohrrr.  I’m liking this.”  Her long green tail swished with excitement.

“Now for the fun part.  You can’t leave this room.  You can’t say anything at all, except ‘Stop’... and you know what that means.  No more playtime.”

Robin nodded, purring her acceptance.

“One last thing.  Change your body so that when you get aroused, you end up with boy cat parts... no spines, though.”

“Mowr!”

“Hey, you accepted this deal.”  Leon tied a ribbon around Robin’s wrist, then took the ring and the ribbon back.  “Now go stand in the corner with those big ears pointing away from me.”

While Robin grumpily did so, her swishing tail showing her displeasure, Leon turned to the inert form on the bed.  He slipped the cats-eye ring on her finger, and murmured instructions into her ear.  Carrie-Lee’s body became the twin of Robin’s, except her fur was jet black, offset by brilliant green eyes.  “You can’t leave the room.  You can’t speak, you can only vocalize like a cat.  Oh, and you see and feel Robin’s shaft as if it had proper feline spines on it.  You have no conscious access to anything that has been said since the collar went on.  Now wake up.”  Louder, he added, “Robin, cancel the stand in the corner order.”

Carrie-Lee sat up in the bed, mewing in confusion.  She looked around, saw Robin, and started to purr as her kittygirlfriend approached.

Leon tugged Jean toward the door, and nudged her out of the room.  “Two more things.  You’re both in heat.  And Carrie-Lee... pain is pleasure.”

The door closed on the two catgirls moaning in lust.  From outside, Leon heard Carrie-Lee’s yowl of surprise and alarm, and grinned.
