Bathroom Growth

Rainbow Dash lies on top of Joe in the bathtub. Dash rubs her butt against Joe's throbbing member as the two are interlocked in a kiss. The hot water ran over the two, only fueling their passion. Joe massages Dash's extended wings, causing her to moan into his mouth. They break the kiss, looking into each other's eyes with knowing smiles.

"I love you, Dashie," Joe says, wrapping his arms around her body.

"I know," Dash says with a smile and half-lidded eyes. "You also like something else everyone can see," Dash moans as the magic takes hold of her body. The tingling pleaser of the purple magic consumes her body. Dash moans as her plot grows 4 inches bigger. Joe slides his hands down to her plot and starts massaging her growing plot, pushing his fingers into her soft behind. She moans in pleaser as she continues to rub her butt up and down his shaft. He grunts in pleaser as her butt almost engulfs his dick.

"You're getting good at that," Joe says between grunts.

"Tell me I have a bigger plot than everyone else you have ever seen," Dash says before kissing Joe again. Joe closes his eyes as he runs one hand behind her head as the magic returns and causes her to grow again. Her butt slowly plumbed up to an 8-inch diameter. Her body is now the same height as Joe laying down. The two separate with a strand of saliva hanging between them.

"You have the biggest butt than everyone else, and no one can tell you otherwise," Joe says, rubbing himself against her plot. Dash shivers and moans as the magic returns and pumps her plot up again to 10 inches.

"How about we get to the real fun," Dash says, pushing down Joe's dick so it was flat against his stomach. She sits on top of it. She looks down at Joe with a smile. Joe smiles back, knowing what she's about to do. "Everyone will be so jealous of your big, fat, dick," Dash says seductively while rubbing her plot up and down his shaft. They both moan as the magic transfers from her to his dick. His shaft grows to 8 inches long and a thickness of 2 inches in diameter.

"I'm pretty sure everyone will be more jealous of you rutting me with that big ass," Joes says as he tenderly squeezes her big plot. Her eyes roll back as she moans at the ceiling. Her body grows taller as her butt grows bigger. Dash's wings now scrapping the edges of the bathtub stall.

Dash recovers from the surge of pleaser. She looks down at Joe with a smile before leaning in close and raising her plot high into the air. "I hope you are ready for the real fun everyone else gets to only dream about," She whispers. She shutters as her butt grows big enough to touch the wall and the glass door to the bathtub. She moans at the cold touch of the glass. "I will never understand you humans and your obsessions with doors."

Before Joe can respond, Dash kisses him again, almost eating his face, as she lines up her slit with the tip of his throbbing dick. Joe wraps his arms around her now giant neck. Dash drops hard onto his dick, causing him to moan into her mouth. She moans back in response with a cheerful tone. She separates from him, the two looking into each other's eyes.

"I love you," Joes says with a big goofy smile on his face.

"I know," Dash response before thrusting her hips up and down as fast as she could. Joe lets out a loud moan, pleaser shooting through his body. Dash releases her own moan of pleaser as Joe thrusts up every time she comes down.

Joe slightly recovers before taking his hands and starts massaging her plot. He sinks his hands into her big plot. Dash moans loader before Joe says, "Everyone must be jealous."

Dash grunts as the magic grows her plot bigger. Joe's hands are now deep in her pushing plot as it squashes against the side of the bathtub. The rubbing of her plot from Joe's hands and the bathtub, causes her to moan louder, and her voice cracks. The familiar presser starts to build up inside of Joe and Dash. This only makes Joe thrust faster. His hips bury into Dash's thick hips.

Dash notices the speed change and starts to speed up to keep up with him. Joe barely holding on as the pleaser builds up to its climax. Joe digs his fingers into her plush rump and thrusts himself into her. He grunts as he releases his cum into her. Dash moans from his ruff touch and the warm feeling of his cum inside of her. Dash's eyes roll to the top of her head in pleaser as her tongue falls out. The two lay there in the afterglow. Unknown to the two, the cum was triggering Dash's magic.

She starts to grow bigger very slowly. She grows 2 inches per second as her plot gets rounder by the second. Joe recovers first and sees Dash now towering over him. Her head almost hits the ceiling as her plot pushes against the side of the tub. Her wings break the glass door, the pieces falling to the ground outside of the bathtub. Her body finally slows down when her back hits the wall.

Dash blinks and slips her tongue back into her mouth as she finally calms down from the giant climax. "Looks like you lost control," Joe says, resting his head against her thigh. Dash looks down at Joe with a warm smile.

"I guess we need a new door now," Dash says, carefully maneuvering herself out of the bathtub.

"We can deal with that later," Joe says, standing up. His eyes look over her new figure. She basically filled the room from ground to ceiling. Her plot makes up at least half of her body.

"Looks like someone is ready for round two," Dash says, smiling as she bends down and wiggles her plot in the air. Her butt took out the light hanging from the ceiling. The two look at it as Dash's face turns red. "Ops,"

"You're right, I am ready for another round, but about you lay down on the floor?" Joe asks as he steps out of the tub. Dash turns her butt towards him and lays down on the ground. Joe rubs his hand across her giant cutie mark. She shivers in pleaser, sending her wings straight out and breaking the mirror. "looks like someone has a sensitive butt,"

"I guess that's another thing to tell Twilight later other than mutual orgasms," Dash says. Joe rubs his dick up and down her big ferry plot. He moans as he feels her soft, wet fur against his hard dick. He presses his hands into her plot, his hands being eaten by her butt. Dash shivers and moans as the loved Joe was showing to her massive plot.

"Could you give me some love for everyone's sake?" Joe says as the purple magic takes over Dash and slowly makes its way towards him. Dash closes her eyes and concentrates on Joe's dick. Joe lets out a moan as his dick grows longer and thicker. Joe smiles at his new size before pushing his dick against her plot. Dash moans as Joe thrust faster, feeling her nice soft ferry plot against his big dick.

"You really love my butt, don't you?" Dash says, looking back at him with a seductive smile. Joe looks over and smiles up at her. He looks into her big, beautiful red eyes.

"Everyone likes the size of your body," Joe says as Dash lets out a high-pitched moan. Dash's body is gripped by pleaser like never before. She melts into the ground as she rubs her hind legs together. Her slit dripping wet as her butt grows bigger. Joe sighs in pleaser from Dash's butt rubbing against his dick. She stops growing as Joe grabs her butt again. He starts thrusting hard and fast against her cutie mark. His thrusts cause her butt to giggle across, causing Dash to moan in pleaser. Joe climaxed quicker, from the sensation of her soft hindquarters to her soft fur. He grunts and lets out his load onto her butt. The white cum landed on top of her plot. Joe sighs and relaxes, rolling onto his back and laying against Dash's plot. He sinks slightly into her as she shivers.

The magic returned to her body, causing her plot to grow even more. The cum disappears as the magic stops. "Looks like it's not just when it's inside," Joe says, rolling to the side to look at Rainbow Dash's giant face. He slowly and lovingly rubs his hands around her giant butt.

"Now that you had your fun," Dash says, looking back at him. "Could you help your mare out?" Dash asks with a pleading look as she rubs her back legs together. Joe smiles and nods as he makes his way behind her and in between her butt cheeks. Her plot takes up most of his view of Dash. He is barely able to see Dash's head from over her enormous plot. He looks down at his dick throbbing against her giant slit.

"Hay Dash, can I have a little help with the size difference?" Joe asks, hugging her plot and hotdogging his dick in between her massive cheeks.

"Sure thing. I just hope everyone else doesn't get jealous," Dash says as the magic takes hold of her body. She directs it towards the little human hugging her butt. The magic takes hold of Joe. His tongue slips out as he sighs in pleaser. His dick and body start to grow. He grows just enough to be able to hug her entire plot. His dick grew up to 3 feet long and a foot thick.

"Thanks, I think you're going to like the outcome," Joe says, grabbing her butt with both hands as best as he can and lining up his dick with her dripping slit. Joe slowly slides his dick into her, he grunts as her tight wall grips him. Dash shivers and moans as the massive dick slides cleanly into her. Joe squeezes her plot as he methodically pulls out his dick to just the head. Dash whimpers at his slow pace.

"You're going to slow, everyone is growing impatient," Dash says, emphasizing the word grow as the magic return to her body. Joe shivers as he slides his dick back in at that moment. His body grows again as her butt does the same. His head almost hits the ceiling as his hip is devoured by Dash's massive rump.

"Calm down, or else this private show will become watchable to everyone," Joe says in a slightly evil manner as he slowly pulls back out. Dash rolls her eyes as she sighs in pleaser. Her plot now bumping both sides of the room. Joe slams into her, causing her rump to giggle and hit the walls. Dash moans with watch slow but powerful impact as her climax starts to build up. Dash whines as Joe pulls out and stops for a few seconds. She wiggles her plot back, trying and failing to slide his dick back into her. "Looks like someone likes my new size," Joe says, gripping her plot as hard as he could and slamming his dick into her. He smiles, and instead of his normal slow pace, he leans his body against her plot and starts thrusting with all his speed and power into her plot. Her butt giggles with every thrust, causing Dash to shake too. Dash shutters from all the pleasers as she turns into a mess on the ground.

She drools on the ground as her climax starts to skyrocket from his giant throbbing dick and his speed.

"Yes, please," Dash whines.

"Tell me exactly what you want Dashie,"

"Rut me so," Dash tries to chock out between Joe's thrusts, but the pleaser is starting to overwhelm her. The feeling of his hands on her massive plot and his giant dick thrusting into her is starting to become too much for her to handle. "Rut me silly with your big cock,"

"Then everyone must see its glory," Joe says as he starts to speed up more as the magic surrounds Dash. She no longer has control as the magic envelops Joe. The two let out loud moans as the two start to grow. Dash's plot grows to the point where it takes up half the room and is being pressed by the walls. Joe now has to bend over on top of Dash to continue to fuck her. His dick growing inside of her causes her to go over the edge and let out an ear-piercing moan. Loads of her mare cum spill out onto the floor as Joe continues to pound his dick into her.

"Just wait until I cum, you will be the biggest bitch in the world," Joe says, but Dash doesn't hear it. She is lost in the world of pleaser of her ass and his giant cock thrusting into her now small slit in comparison.

"Please cum in me," is all that comes out of her mouth.

"As you wish my mare," Joe says, smiling. Enjoying the fact for once she was the one begging for him. He thrusts one last time and lets his load into her. Her eyes shoot open as the warmth fills her up again. Her body grows at an alarming rat. Her plot fils up most of the room, pinning Joe to the wall. The rest of her body fights with her plot for space. Joe relaxes as he relishes in her colossal plot.

"Mabey next time we try and not destroy the room," Dash says in her haze. Her muzzle slightly crunched against the wall.

"That's no fun," Joe says, squeezing her but.

"I think I already have an idea for next time," Dash says, wiggling her plot into him. "Now time to return back to normal so we can get to bed,"
