The game

-rules of scat: 3 cards per person, draw one card from either the draw pile or discard pile at your turn. points are counted per suit. Who ever has least points at the conclusion of a round loses a life. maximum points obtainable in a turn is 31 which requires an ace of that suit. Each round is completed when a person "knocks" and every other player has drawn one more time. A player may not draw a card if they knock. Face cards are 10 points. Each player has 3 lives.

“Ok ok ok.” Eve said laughing.

Eve started and one by one they took their turns picking up cards until the second time around Celise “knocked” on the bed.

“What? Already?” Eve said with a worried look on her face.

“Look at her Cel, she’s shaking in fear!” Ivy prodded.

“I can’t wait to turn her into a walking goo monster!” Celise grinned maliciously

“Hey! I thought we said no monsters!”

It went around back to Celise where unsurprisingly Celise had the highest score with a respectable 29 and Eve the lowest with 13 on a 6 and 7 of clubs.

“Fucking useless game.” she lamented

“Hey, if you’re a trash player you can’t call the game trash.”

“What are you talking about? You barely beat me with 15 points?”

While the two talked Celise was staring at Eve in heavy concentration.

“Aha! I know!” A wide grin spread across Celise’s face.

Ivy’s normal composure was broken by her eyes bugging out. She watched as two stumps slowly grew out from under Eve's arms. They extended a few inches every second, long protrusions and at their ends hands with fingers and thumbs formed. Eve now had four arms.

“Uhm.. Celise? Don’t you think that’s kind of stepping over the line there?” It was only the first change and Ivy was already questioning the logic of continuing.

“What?” Eve looked down at herself and didn’t notice anything different. A flush came to her skin at the possibility that she had been changed completely without her knowing even as she tried to figure out what it was.

Celise was just cackling madly with laughter rolling all over the bed messing up some of the cards in the process.

“Hey! Calm down you little monster.” Eve tried desperately to clean things up with her four arms which just made Celise laugh all the harder.

It took some time to calm down Celise. Eve had to threaten to use her power on her as punishment on its own.

The next round was played out similarly to the last. They mocked and jabbed at each other as they picked up their cards. This one actually went around a couple of times before Celise knocked again. They all showed their cards and Eve got a chance to get back at Celise. “Hmmm..”

“Hey Eve what she did to you was horrible, you shouldn’t hold back.” Ivy whispered just loud enough for Celise to hear.

“HEY! No helping! And no Eve I uh was very not horrible! You’d actually really like it if you knew!”

Eve continued to tap at her chin with both of her left hands The two right were passing a card back and forth. Then she grinned.

Eve and Ivy watched two holes appear in Celise’s shirt right where her nipples should be. Flesh pushed out of the location and two adequately size dicks swelled out and flopped out.

“OK that’s kind of fucked up.” Said Ivy.

“What?!” Celise whined. “dah! I hate being the one changed! What the fuck did you do?”

Her sister having two dick nipples was bad enough Ivy thought but what made it worse was as they played the next round Celise would idly stroke one then the other always keeping them semi hard and leaking some clear liquid.

The next round Eve started with a great hand and knocked immediately securing her win against Ivy.

“Its probably going to be something disgustingly perverted.” she thought. “Oh well, its just a part of being her sister.”

“Done.” Eve said

“What? I don’t see anything different? Celise said.

“It’s a mental change, you should see it pretty soon.”

Ivy shivered though it wasn’t cold.

The next round went quickly with Celise again knocking. Except when it was Ivy’s turn to draw she dropped her cards and yelled “SCAT!” triumphantly.

"wait, so does that mean she gets to change both of us?" Celise asked.

“Sort of? I wanted to make it a little more special than that since its pretty rare. For scat I made it so it works like winning. You get to change each of us and we won't know what you did to either of us.” Eve was panting slightly at the thought of her changing and nobody knowing the wiser. Both Ivy and Celise were looking at her with worried looks.

Ivy had noticed the difference between Eve and Celise’s changes. Eve yes had her four arms but besides behaving like she had always had them there wasn't much difference. Whereas with Celise and her.. Dick nipples. She clearly thought she was supposed to always keep them hard and leaking. So it looked like the changes weren’t actually limited to one thing and you could tailor them to a theme.

“Let's see then.. For you Eve, something a little bit interesting but not too weird.. And maybe it’ll help you a bit.. There!”

Eve began to massage her cock in a very sensual manner. Her posture and mannerisms changed completely. Every movement of her body and face was as if it was meant to excite the libido. Her four arms were everywhere, tempting the imagination of any who looked. Next a thick smell diffused in the air beginning to make it too difficult to think about anything but that beautiful dick. Ivy wondered idly at what it would be like to be fucked by it.

Breathing heavily, her chest rising in great strokes Ivy continued on.

It took her a moment with the haziness in her mind but eventually she knew what she wanted for Celise.

The leaking in her dick nipples suddenly increased substantially and her breasts started to grow out going from their nice size at a large c. They just kept going and going. They reached the size of Jane’s balls and kept going. They finally stopped where they were just large enough that Celise was just barely able to reach the cocks that still protruded from the end. These also were slightly larger now at maybe 9 inches erect but substantially girthier than what you would normally see on a dick of that size.

“Hey Eve could you help me with milking?” she had a strained look on her face.

Eve grinned a flush coming to her face. Changing her from leaking milk all the time to having two dicks expelling cum endlessly that she thought needed to always be hard was driving her libido into the stratosphere. She helped her sister stand up by lifting the insane chest and brought her down the hall to the bathroom where eventually loud moaning could be heard from the bedroom. “Yeah that was a great change.” Ivy thought “subtle and it would bring them closer than ever.” Eve spent her time milking her sister into the bathtub slowly fucking herself with her retractable dick. Not enough for her sister to notice though.

It took a while for her sister to be emptied out, her chest was now only about the size of Jane's nuts. Ivy wondered when the next time Celise would need to be emptied.

When they had returned they got right back into the game. The next two rounds Celise won. The first was a change to Ivy. Deciding to be nice she decided to make it so Ivy could change how she looked at will. To Celise’s surprise Ivy immediately changed into a more sexualized version of herself with a larger butt and boobs that bordered on impossible. Her hips widened and from just above her sphincter 3 slimy tentacles slid out and wriggled around her. Their tips flared out in penis shapes. She lightly petted one of the cocks like it was a dear pet and shivered as it apparently brought her great pleasure. Celise frowned in confusion.

Eve’s mouth was watering at the sexual goddess, her own hands running over both her nipples, her cock and fingering herself around the base of said cock at the same time. She mouthed to Celise “you did that?” Celise shook her head and shrugged. Eve wondered if maybe her last change was somehow coming into play here. She hadn't been able to see any changes made by Ivy yet so she couldn't be sure. She had tried to liven the game up by making it so all of the changes Ivy made would be perverted no matter what and she wouldn't realize that they were so. The thought had her cock ramrod straight.

The next change was to Eve and was her game losing change. Celise thought she should stick with the theme of doubling something.. Ugh, her dicks were getting soft again. She wanked them a couple of times ensuring the fluid kept up its leisurely expeleture. Eve’s sexual fog could be really annoying sometimes. It was so thick and pungent that oftentimes in order to get to bed they had to ease the sexual frustration with some mutual gratifaction. Usually they just accomplished this by having Ivy and Eve riding on Celise’s nipple cocks for a couple of hours. That might change now with Eve having a cock of her own.

So feeling horny and churlish at Eve she went with the most obvious change. Eve’s Vagina suddenly shifted over and right next to it appeared another. The one that had been there from the beginning still had it’s heavily veined cock extended out fully hard. The difference being that it was now much wider than it had been before. The outline of Eve’s other cock could be clearly seen in the bulge it made in her belly. her belly at that spot stuck out a good inch or more. There would be no hiding it. Then the member started to move in and out of her pussy, each time moving just far enough that the head would protrude just past the lips before sliding back in. Eve was moaning and moving about in a way most sexual. Her un-moving dick was standing stiff as she fucked herself with the other.

The sexual stench had grown in the air to the point that none of them could stop themselves anymore. Celise reached around her insane boob-age to finger herself. Her dicks were at full attention leaking a profuse quantity of her pre. Ivy had all three of her tentacles at work on her own holes. One penetrated her mouth, another in her anus and the last in her pussy. All three were shoved down so far that they were all taught outside. Clear lines could be traced where the one in her pussy was bunched up in her own womb. The two going to her butt hole and mouth clearly shown the anatomy of her inner tunnels in large swirls and twists of their great bulging masses. A feat normally impossible that her new body now had no problem accommodating.

They all came explosively. The quantity was staggering and soon the queen bed was soaking with a layer of fluids (mostly cum). Sticky and white they all fell into the puddle. “How did we ever let you talk us into playing your stupid game. Of course it would end with us all cumming our brains out. I have no idea how but obviously this was going to happen you little perv.” Ivy said into the puddle of cum. Her speech made little bubbles in the cum around her face.

Eve giggled carelessly into her own sperm puddle, her own cock still pumping in and out of her left pussy.

The last round was played out on the small table in the kitchen (that they rarely used). It didn’t even have chairs so they just stood around in their cum drenched nudity.

“Let’s get this over with I want to see what people say to us!” Celise said.

“They shouldn’t say anything, to them we will all look completely normal.”

Ivy noted how Eve’s posture was at odds with how she spoke. She spoke the same way as she always had and yet every time she moved was suggestive in the ****. She seemed to have a natural high heel stance which only accented her nice derriere. Her arms never stopped their sensual paths up and down and around her sensitive parts. “What a great change.” She thought.

The last round Celise had her head down in concentration as if it was some deeply strategic game. Her enormous boobs were pushed down onto the table. The cocks leaking their pungent fluid. Ivy was poised with a light of confidence in her eyes. Her tentacles wrapped about her in imitation of a throne.

Celise knocked a few rounds in. Ivy raised a brow as if to say. “You dare challenge me mortal?”

She drew her card and a moment later discarded. She waited holding the tension high. She slowly lowered her cards down at the same time that Celise tossed down her own cards and yelled out “30!”

Ivy just calmly waited out Celise’s self celebration. She almost in a bored tone said“scat.”

Celise stopped her joviality and swung about and looked down at the table. “Fuck.”

“Let’s see what should I do.. It is the last hand so it should be special.. Yes?”

“Definitely! Turn her into a puddle of goo or something!”

“Shut it Eve! Um.. Ivy, I’ll do your chores! I’ll do anything! See I’m a good person and you wouldn’t do something bad to a good person right?”

“No.. I guess you’re right. If you’re willing to do all of my chores for a while then you must be a good person.”

Celise sighed with relief.

“Hey, that’s cheating! You can’t use bribery to save yourself!”

Celise turned her head and stuck her tongue out at her sexually charged sister.

“Very well, one month of my chores for a reduced change.”

“Uh.. two weeks should be..” Ivy quirked her brow at the intrusion. “Fine.. one month..” she finally mumbled out.

The change was immediate. Celise’s posture changed to one of lithe grace and long flowing movements so even as she stood she seemed to wave about. From her pantied behind a long tail sprouted and waved in the air. Atop her head two cat ears appeared and wiggled about like they were independently sensing the world around them. A loud, constant and rumbling purr could be heard from her. She grabbed one of her cock nipples and began to lap at it ensuring its hardness.

“It’s almost time now to go, should I go see if Jane and Alice want to join us?” Eve said.

“Yeah I bet they’ll love to come along, besides I need to catch up with them. Somehow I've barely seen them lately.” Ivy said.

“What fun!” Celise jumped in the air, her hands bent in that way cat girls like to do. Her vast breasts jostled everywhere in her wake flinging great drops of cum all over the kitchen.
