Within the private chambers of Bowser's Castle, Mario could barely hold back his grunts each time the tightening, heated and moist fleshed continues to milk his shaft. He looked up at the face of the lecherous woman enthusiastically taking his member into herself. The female in question bares the appearance of the mushroom princess.

Bowser- or in this case, Bowsette, as she dubbed herself, huffed and grunted as she rolled her hips, bouncing on her archrival's cock. A lustful smile revealing her sharp teeth, her tongue licked her lips to gather the drool slipping from her maw as she revels in the pleasure. Her perky large breasts wobble with each movement, her pink tits fully erect and sensitive to the touch as she'll occasionally tease them. The humanized koopa's ruby eyes glanced down at the man with a large grin. The flow of her rhythmical hip movements didn't slow down not even for a second.

"Peach will be so jealous." She huffed with a noticeable strong tone.

Her voice brought the plumber back to reality. He didn't realize his hands were groping her shapely ass, he can practically feel the soft skin through his gloves. The contact was greatly accepted evident from Bowsette's tail wagging joyously. Her wide baby making hips were voluptuous and complimented her firm leg muscles.

"This plan is brilliant! She'll be-beg for us to come back to her!" Bowsette bite her lips after a throaty moan escaped, the heroic plumber's member made direct contact with a sensitive area within her volcanic pussy. "We need to…k-keep training. Get ready f-for re-revenge!"

Her hips switched from bouncing to grinding their bodies together at a rapid pace, firmly pressed to the base. Neither of them is close to hitting their respected orgasms yet, despite going at it for nearly an hour. The large king size bed jittered and creaks to its limit, soon to reach its breaking point and falling apart. It was the least of Bowsette's worries. She was more focus on how full and stretched out her pussy felt around the plumber's engorge member. The feeling of her clit sliding on another's heated flesh sent tingles of electric sparks through her core and shivers up her spine. Her snatched leaked plentiful of juices around her partner which pooled and stained around the bed sheets.

Mario clenched his teeth. He couldn't help but marvel at Bowsette's form, the way she looked so similar to Peach, despite knowing who she really is. The sweat coating her body shone from the candle lights and her breathless filled moaning as she rode him override his concerns of the matter. Her vaginal walls kept massaging him uncontrollably and refusing to let up.

Was this really all for revenge or was it something more? After saving the princess and getting harshly rejected Bowser was quick to come up with a plan as he presented Mario a crown object.

At the day of the tennis tournament their plan was set into motion and the end results was worth seeing Peach's face when Mario appeared on court with his doubles partner. The Super Crown had turned Bowser into the bombshell hottie, Bowsette, two horns, a spiky shell, and blonde flowing hair. She wore a similar sporting outfit to Peach, only in darker colors. The enlargement of her breasts pressed so firmly against the top fabric her nipples were practically seeable, and her cleavage threatens to pop out from her movements. Her tail even hiked up her outfit enough to flash her bubbly ass and panties.

However, humiliation wasn't enough in Bowsette's book. She desire to achieve a higher objective; the perfect cuckold. Mario bared his teeth and grunted from the sudden pull of Bowsette's hips moving upward, her snatch firmly gripping like a vice once again. Her pointy fingernails gripped the plumber's shoulders, keeping him secured in place. Mario's shaft was smeared in her juices and being exposed to the cooling air. The tip of his cock was the only piece of him clenched to the toasty space of Bowsette's inner pussy, making him wish to be put back in. The koopa woman's tail sways side to side in anticipation, her ass hanging a few inches in the air.

"We need to practice more." Bowsette declared with a glint of lust sparked in her eyes, her lips quickly forming into that mischief smile. "We're not yet ready for our assault against Peach. We gotta break. This. Body! In!"

She punctuated her shouts with each downward thrust, her ass bouncing and her tail held high. This drive to finally get back at the princess serves to fuel her further into a wild frenzy of lust. Mario wasn't able to think anymore, all that matter now was the pleasure, his cock getting milked and the hot melting sensation that came with it. He contributed by consciously rotating his hips upward to try and match the pacing with his archrival with benefits.

Bowsette's moans weren't held back at all, she has become vocal and uncaring. Her tight pussy was constantly ravished; the shaft fit like a glove and filling every space sending shockwaves of ecstasy. Her g-spot especially getting the full treatment making her eyes roll and her senses clouding away everything but the sensation of pleasure. The large bed shook even more than before as she and her partner going all out.

"Yes! Yes! So good! Yes!" Bowsette's repeated chants were the loudest and hypnotically enticing to the man's ears. The whole residents within the castle grounds wouldn't need to ask questions from the sheer volume.

Bowsette leaned forward and pulled Mario's face into her bouncing breasts, smothering him between her arms and large assets without losing a beat in her thrust. All of her concentrations were focus on working her hips harder and faster, her movements became erratic as she continued to moan as loud as possible. Bowsette's mouth hung open and her vision blanketed out of focus. She clenched the plumber closer, embracing him onto her bosoms as she hit a fever pitch and couldn't stop even if she wanted to.

A few more hard thrusts until Bowsette finally reached her breaking point. Her head shot up as a thick stream of smoke pour out of her mouth. "FUUUUCK!" She shouted with a mighty whale, her hips till gravitating into a slow grind. She constricted several times around the plumber's shaft as a flood seeped out of her pussy. The molten river of her orgasms was too much for Mario to handle as he blasted a load straight into the depth of her womb, and then another, follow by another blast of hot cum. A dopy smile graces the koopa woman's face; a silent moan escaped her lips as her eyes looped from getting a hot cream filling, her tongue lazily hanged loose and the smoke from her mouth slowly died off.

After what felt like hours on the ride of their afterglow wearing down, Bowsette lazily rolled off her partner, groaning from the combination of aching stiffness, pain sores, and satisfaction. Mario's cock has soften and popped out of her twitching and leaking cunt; goop of his seed poured out like a river and mixed together with her own juices on the bed. Mario took a moment to gulp fresh air until his light headedness has settled down for him to think. He then glanced over at the tall woman, glistering in sweat, her breasts heaved with every deep breath she took, and her lower region covered in the evidence of their scandalous lovemaking. The heroic plumber's eye widen as he came to profound realization…

Mario fucked Bowser. Not a Peach lookalike or this Bowsette persona. He had sex with his archenemy, the guy who tried to end his game more times than he can count, the King of the Koopas himself!

"Hey." The hush voice next to him snapped Mario out of his emotional terminal of his confused sexuality. Bowsette stared back with half lidded eyes and a fang smile. "That was some intense training." She took a moment to observe her form, marveling at her sweaty body and stretched her arms until the muscles popped. "Bwoh, ho, ho, man…this bod can still hold out! This crown power is something else!" She stated as she adjusted the Super Crown on her head. Bowette blushed from a sudden thought, a sultry smile dawn her face. She plop herself on an elbow and reach out as her sharp fingernails gently twirl around the plumbers belly next to her. "Soooo, ready for round 2?"

Mario's voiced hitched in his throat. He wanted to say something, anything. This wasn't the 'petty revenge on Peach 'cuz she hurt my feelings' plan anymore. This is an entirely different thing!

"Heh, heh, what's the matter, not motivated enough?" The koopa woman then crawled in front of the plumber; she turned her back displaying a green spiky shell and tail that's covering her rear. She looked back over her shoulders with taunting ruby eyes lining up with his blues. "Well…how about we train this spot next?" Before Mario's eyes Bowsette lifted her tail giving him a perfect view of her soft puckered anus.

The plumber's 'Small Mario' slowly became 'Super'.
