Maxwell couldn't help but stare as he watched the three combatants leap around the simulated play field. Their skill in combat was from more than just their powers, it came from years of training and on top of it they had basic combat skills to begin with, Maxwell realised he had a long way to go as he glanced down at his notebook. Granted his ability to create anything was an advantage against his opponents, but if they didn't beat him while he was writing, his low skills in combat would surely get him killed.

The particular battle Maxwell was watching was a three-way duel between Rosalina; Mega Man; and Fox. Maxwell watched in awe as the three very skilled combatants put their skills to the maximum capability. Then everything started to go downhill as a red mushroom dropped in, Rosalina want for it, completely unaware of the nearby bob-omb that had started to walk in the direction of the mushroom. Just as Rosalina was grabbing the mushroom, the bob-omb bumped into it, causing it to not only explode, but to grow. Resulting in a colossal explosion that blew all the combatants away and left a gaping hole in the stage.

Mega-man and Fox staggered to their feet but Rosalina didn't appear so lucky. She was lying unconscious on the floor and the three boys immediately rushed over, attending to their hurt friend. She woke up and held her hand to her head as the boys sighed in relief, "Wha...what happened?" she asked, "We have no idea." Mega-man said, "We just know there was an explosion." Rosalina nodded as she staggered to her feet, "At least I was the only one...UGH!" She suddenly keeled over at the stomach as the strangest thing began to happen...She was growing.

It was slow at first but began quickening as tears were heard from her dress as she outgrew it and stretched the material, she seemed to be in pain but mostly just looked confused as she reached a height of at least 14', shredding her dress and leaving her in her panties. She blushed as everyone watched her gigantic breasts sway back and forth, "I never saw the point in a bra." She admitted through gritted teeth. She continued growing, reaching 17' when her panties finally snapped, sending the stretched undergarments hurtling towards Mega-man at a speed that knocked him over on contact. The young princess kept growing until she was reaching the ceiling then she finally stopped, Rosalina glanced at her situation then screamed an ear-piercing scream that shadowed the glass in the room. Fox waved at her and she stooped down, holding her hand out so the three boys could climb on. She lifted them up to eye level and Fox spoke, "Are you ok Rosalina?" She nodded hesitantly, "Can you undo this?" She asked fearfully. Mega-man looked at her, "I don't know Rosalina, we might have to call Mario or…" "NO!" she screamed so loudly it knocked Maxwell over. "Sorry," she blushed, "just don't call anyone else, I don't anyone else to see me." Fox groaned, "What are we supposed to do then?" Maxwell spoke up softly, "umm, I think I can do something." Everyone looked at him expectantly, He held up his notebook, "Of course!" Mega-man exclaimed, "He can create anything!" Fox nodded then asked, "What can you make?" Maxwell thought then decided, "A potion, specifically a medium potion, it will most likely return her to normal size." Rosalina nodded quickly, causing her boobs to shake violently, " Make it! Please!"

Maxwell nodded and took a deep breath as he opened his notebook, writing in carefully the word, medium potion. He was just about to make it appear when he had two thoughts, what he had seen when he first arrived and what Fox had told him earlier, he erased the word and wrote in medium horny E-cup potion. As soon as he finished the potion appeared in front of him, he picked it up and carefully holding it out, "Set us down then drink this." Rosalina nodded as she carefully grabbed the potion and set down the boys.

She took a deep breath and drank the potion, rapidly shrinking down to her regular height except for her breasts, which were know three cups bigger than before. Once she was normal she passed out and Fox sped over to catch her. Then they noticed she was absently muttering, "Sex...need, sex." Fox looked confused and maxwell winked, "The potion also made her extremely horny, she'll want to have sex with the first person she sees. Who wants her?" Mega-man scoffed in disgust, "You're sick Maxwell. I thought you were helping her?" Maxwell shrugged, "I did, I just threw in some bonus." Fox smiled, "May I do it? It's all I can take not to fuck her right now." Mega-man growled but nodded, Maxwell waved his hand toward the elevator. Fox nodded in thanks and bridal carried Rosalina into the elevator, going to her floor.

Mega-man turned to Maxwell and glared. Maxwell laughed, "What? Just because i'm a kid doesn't mean i'm good. I can do whatever I want, so I do." Mega-man growled, "I still think that wasn't right. You took advantage of her." Maxwell smiled evily, "Duel me over it then. Come on, you and me, in the arena." Mega-man considered the offer and nodded, signalling to R.O.B. to reset the stage.

Rosalina awoke extremely wet and completely naked in her bed. She looked around and found Fox next to her, also naked. She looked him in the eyes and said, "Fox, I need you to have sex with me. I don't know why. I just do." Fox nodded, "Sure. I'll have sex with you." She smiled in relief and climbed on Fox's dick, using his shoulders to push herself up and down and rubbing her breasts in his face, the sweet relief sex brought was amazing and she moaned in pleasure, "Oh Foxxx." She sighed, speeding up her bouncing as he too softly moaned and began rubbing her E-cups with his furry hands. Massaging them softly, provoking more loud moans from Rosalina as she reached an orgasm. Screaming in pleasure.

The two kept at it until Fox exploded cum into the inside of Rosalina. She was moaning in pleasure when her head suddenly cleared and she realized what was happening.

She leaped off Fox's dick and slapped him hard. "Fox what the hell!" She screamed, Fox looked at her in shock and stammered, "You asked me too." Rosalina's jaw dropped and then she remembered, "I'm going to kill Maxwell. What was in that potion?" Fox shrugged, "All I know is it shrunk you and made you horny." Rosalina turned bright red in anger and gasped as she looked down. "That twerp blew up my tits!"

Rosalina quickly pulled on panties and slid her dress on, then she turned to Fox, "Put your clothes on and get out you perv!" Fox nodded and hurriedly pulled his clothes on, racing for the elevator. Rosalina joined him and headed for the battle room while Fox went to his penthouse.

"Guess you learned your lesson huh Max?" Mega-man teased as Maxwell his now broken arm, "Shutup Mega-man." Rosalina had marched in and beat the shit out of him. He staggered to the elevator and collapsed as soon as he reached his room.
