In the ever gloomy and dusk-like setting of Twilight Town, Mario and his companions managed to defeat the duplighost that haunted Creepy Steeple and put an end to his 'pranks' of turning people into pigs.
Right now, they were taking a break before making their next move. However, the Mario that was with them is actually the very same monster. He uses his trick to become Mario and switch bodies, now becoming the hero himself.
It was ridiculously easy. Hell, even that nerdy Goomba girl, Goombella, couldn't tell! He was praised and revered as a hero, not even the townspeople realizing it was the same creature literally giving them Hell just a while ago.
But the monster named Doopliss, he was getting rather bored. And these goody-two-shoes were cramping his style. How can he possibly have fun and pull off pranks like this? But then, an idea formed into his head.
'Wait a minute. I'm Mario right now! I can basically do whatever I want and these idiots would fall for it!' He thought to himself as he grins. Oh, he has plans of ruining this guy's reputation. Might as well have some fun before he moves on.
But what should he even do? There was a couple that stood out to him. That Koops guy for starters.
'Hard to believe a subby bitch like him has a girlfriend! Ppht! Puh-lease. He's DEFINITELY a bottom~' Doopliss thought to himself lewdly, and then thought of the Yoshi Kid. What did he call himself again? 'Gonzales Jr.... weird name. But whatever. He's quite cute. I heard Yoshis were quite fuckable.'
Doopliss knew what he had to do. These two pretty much looked up to Mario. From what he can tell from hearing their stories, this guy boosted Koops' confidence slightly, and this Yoshi admired him since he was raised and born in some arena? Well, who cares.
They'll be his from now on~ He just has to get these dumbasses away from the group. And even if he does lose this body and go back to normal. Who cares? The damage will already be done. This will be the best 'prank' he's ever though up!~
"Hehehe... time to put my plan into action. Operation: Cumdump is a go~" Doopliss whispered to himself as the group were ready to rest at the Inn. He sees the shy Koopa male and the Yoshi. Perfect. The rest of them? Don't even matter.
Doopliss chuckles to himself. It was time to put his plan into action, now he just needs an excuse to get these gullible idiots alone with him.
'Let's see…' He thought. 'Nothing too big, but it shouldn't be too easy, either.'
Then, an idea came to him. Doopliss chuckled to himself mischievously. He approached both Koops and Gonzales. "Hey, guys; what's going on?" He asked in Mario's voice. Of course, they were none the wiser.
"Not much." Koops replied.
"Yeah, that battle was pretty intense, wasn't it?" Gonzales added.
Doopliss nodded. "I know the feeling." He said. "Although, I HAVE heard of a fountain that boosted morale."
Koops and Gonzales looked at each other, and then back at 'Mario'. "Seriously?" They asked at the same time.
"Dead serious. I thought we could go there and investigate." Doopliss lied. "I don't really want to bother the others with this. Besides, the path there sounds pretty safe from what I've heard."
Koops looked at Gonzales. "What are you thinking?" He asked him.
"Sounds reasonable." Gonzales shrugged. "Besides, now that Doopliss is no longer a threat, we should be safe from any enemies."
Koops looked back at 'Mario'. "Sure, we'll go." He said. "Where exactly is it?"
God, these guys were so gullible. This was making his job way too easy! Still, he has to play along for now.
"If you guys follow me, it won't be too far. Trust me, once you see this fountain, you'll be energized in no time!" Doopliss says, as the two seemed to agree. "Great! Follow me."
Koops and Gonzales followed 'Mario', not aware of who he actually is. This fountain sounded too good to be true, but hey, they've seen much crazier things and including powering themselves up. This seemed rather tame in comparison.
Doopliss led them out of the village and deep into the dark forest. The moon casting overhead and making the area seem something out of a Halloween story.
Koops decided to speak up as he looked around, a little nervous and scared of the environment. He hoped they wouldn't go back to this part of the land.
"S-so... uhm... Where exactly is this fountain, Mario? I would've thought we'd seen it." The Koopa asked him, but of course, the duplighost had an answer.
"Well, this fountain's well hidden. What, you didn't think a magical fountain would be out in the open, did ya?" 'Mario' said, the lie easily coming to him.
"W-well... I guess." Koops had to admit, that did make some kind of sense.
"Aw, don't worry, Koops! Whatevef's out here, we can take'em! After all, we have the brave Koopa and the Great Gonzales Jr.!" The Yoshi said and boasted. Doopliss simply rolled his eyes. Oh, if they knew...
Eventually, the trio made it to a small clear with a structure in the middle. The structure in question? A good fountain spraying water. Koops and Gonzales were awestruck at the sight. "Whoa…!" Koops breathed. Finding it more outstanding than he imagined.
"I'll say!" Gonzales added. "So, what now, Mario? Do we just drink from it?"
Doopliss nodded. "That's right!" He said. "Allow me."
Koops and Gonzales watched as ‘Mario' pull out a couple of mugs and dip them into the fountain. Filling them into the process. Once that was taken care of, he gave them to his companions. Although, the water looked… Different. It had a pink hue as opposed to being crystal clear.
"Is this safe?" Gonzales asked skeptically.
"I've heard some good things about it." Doopliss replied. "It's perfectly safe from what I've heard."
Hesitantly, Koops and Gonzales put the mugs up the their lips and began drinking the contents. It tasted pretty strange, but it was fairly good nonetheless. Once they were finished, they pulled away and sighed.
"I'm not feeling anything yet…" Koops said.
Gonzales groaned. "I knew this was a scam!" He complained. "What the hell, Mar… Mar…"
Slowly both of them began to feel woozy. Like their minds were being clouded up by whatever they drank. Doopliss smiled naughtily. He knew the Fountain of Lust would do the trick!
"How do you feel, boys~?" He asked. "Do you feel… Good?"
The two felt strangely hot and aroused. Koops could feel himself getting warm, his hoodie felt more restricting and his shorts getting a small bulge. Gonzales Jr. felt some constriction in his shorts as he squirms on the spot, panting.
"I... I feel... h-hot... so hot... M-Mario... wh-what... what the hell's happening???" The Yoshi kid asked him, he felt like he just ran a marathon.
"Nnnhh... I-I feel... warm too... wh-what was in that...? Mario... M-my head feels so dizzy..." Koops said, which 'Mario' grins, seeing the effect on them,
"Good. That's a nice sign, guys. You wanna feel REALLY good?~" Doopliss asked them, which caught the two's attention and nodded. "Then I have a good idea that'll make you feel better. After all, you two do deserve this~"
'Mario' approached the two and cupped their chins, making them shudder. He was going to have some fun with the Koopa and Yoshi.
"Would you like engage in some... fun?~" He says, his voice taking on a more sensual and flirty tone.
"Y-Yeah~" They both said at the same time. It was getting harder to deny it, but that fountain's water was really working its magic~
Doopliss turned to Koops. "Why don't you… 'Make yourself comfortable', if you catch my drift?~"
Koops smiled lewdly before he started slowly undressing. Gonzales just watched. His mind also in a haze. Strangely, he felt so… Turned on~ And seeing that Koops was also into it, well, he was pretty turned on~
Eventually, Koops was fully nude. Honestly, Doopliss was impressed at how well-endowed the Koopa was. With that huge dick and bubbly ass combined, he would make a good slut~! He turned to Gonzales who was ogling at him. "Be honest, how does Koops look, Gonzales?" He asked him.
"Y-You look good, Koops…!" He breathed. Koops blushed. He turned to face 'Mario' who gave him a silent nod of approval. Knowing good and well what he was about to ask. Turning his attention to Koops, Gonzales spoke softly. "Need some help with that?~"
Koops shuddered in excitement and swung his cock back in fort. Taunting the Yoshi. "Do it~" He commanded. Gonzales got onto his knees and grasped Koops' cock. Causing him to moan softly.
"You like that?" Gonzales asked. Koops nodded vigorously. "Good~ But how about this?"
After saying that, Gonzales opened his mouth and began sucking the Koopa off. Both males moaning as he did so. Doopliss was amazed by this. Who knew they could be such sluts when magically provoked?
Doopliss approached Koops and turns his head, then he began kissing him. The Koopa's eyes widened before he relaxes, kissing back as the Yoshi bobbed his head, tasting his friend's cock.
'Mario' broke off the kiss, as Koops lets out a moan, feeling his dick getting pleasured. He didn't even seem to mind that another male was doing this to him or kissed him.
"How does it feel, Koops? How's it feel being kissed and sucked off by a guy?~" Doopliss asked, already knowing the answer from Koops' pleased expression alone.
"Nnhh... s-so... good...~ It feels amazing...!~" The Koopa admitted and felt Gonzales Jr. using his tongue for added pleasure, tasting more of the other male's shaft.
"I think he enjoys it as well~" The duplighost in disguise says, hearing the Yoshi's muffled moans and his cheeks flushed.
As it went on, Koops grabbed the sides of Gonzales' head and began facefucking him. "Take my cock, Gonzales! You really are the greatest~" He groaned.
Gonzales just took it. In the heat of the moment, he even began jerking himself off as he felt the onslaught of thrusts down his throat. "How naughty of you~" 'Mario' smirked. The Yoshi responded by letting out a muffled chuckle.
When the pleasure was at its peak, Koops began leaking pre as he went even harder. "I-I'm gonna cum~" He moaned.
'That's it, you sissy Koopa~' Doopliss thought naughtily. 'Cum down his throat~!'
With one final harsh thrusts, Koops moaned louder than ever as he came. Gonzales tasted Koops' seed. It was incredible~ Much better than anything he's ever eaten! Once he was finished, Koops pulled away and allowed the Yoshi to breathe. "Hah… Hah… So yummy~!" He panted.
'Mario' leaned in and whispered into the Yoshi's ear. "I bet you wanna fuck his tight ass, don't you?" He asked.
"Hell yeah~" He replied before speaking aloud to Koops. "Can I… Stick it in you?"
Koops blushed hard, but smiled lewdly nonetheless. "Sure thing~" He said before getting on his hands and knees. Shaking his bubblebutt in the Yoshi's direction. "Go on then, Gonzales~ Fuck me hard!"
Doopaliss smirked. Who knew someone like Koops could be so slutty? Buuut he wasn't complaining~ He watched as Gonzales prepped himself and slammed inside Koops' ass. The two of them groaning loudly as it happened.
"Aaaaaahnn~" Koops moaned girlishly. "That's it; fuck my tight Koopa booty!"
"Ask you shall receive~" Gonzales breathed before thrusting hard into Koops' ass. "Mmgh! Such a good ass~"
The sounds of the two's moans and the slapping of flesh could be heard. Koops' cheeks jiggle with every contact as the Yoshi pounded away, filled with excitement as he gripped onto the Koopa tightly.
"Mmhgh!~ G-Gonzales...!~ Oh, your dick feels amazing!~ F-fuck... being... being screwed by a guy is awesome...!~" Koops panted out, and feeling a harsh smack on his rear, making it jiggle some more and eliciting and girly squeal.
"Mmmhh... yeah!~ Such a sissy Koopa...!~ Man, you put girls to shame!~" Gonzales moans out, and giving out a chuckle.
Doopliss watches this, and see's the backside of Gonzales Jr's ass. Jiggling with every thrust into the feminine Koopa.
As Gonzales was focused on pleasing his friend, he didn't notice Doopliss behind him and transforming back to normal. After all, what can these two do? They ingested the water from the Fountain of Lust.
The Yoshi kid gave a yelp as he felt something inserted inside of him, which was the duplighost's cock.
"Such a fuckable ass...~ How's it feel, bitch?~" Doopliss says and chuckles, thrusting inside the Yoshi.
"D… Doopliss? Mmn… Feels good, actually~" Gonzales moaned.
"Good! That's how you're supposed to feel~" Doopliss replied before slapping the Yoshi's ass hard. "Such a good ass you have~!"

Gonzales winked at him  before thrusting harder to Koops' ass. The Koopa moaning loudly as this happened. "A-Aaah! This feels so fucking good~" He groaned. "Your cock is so great, Gonzales~"
"Heh! Glad you think so, Koops~" Gonzales replied. Chuckling a bit on the wordplay. "I bet you want my Yoshi cum, don't you?"
Koops nodded vigorously. "I do! Oh, fuck yes I do!" He moaned. Sounding like he would die without Gonzales' seed inside of him. Truth be told, Doopliss was getting close as well.
And then, all at once, all three males came at the same time. Doopliss filled Gonzales while he, in turn, filled Koops while he stained his face and chest with his cum. They all practically howled as they came; having the greatest time of their entire lives~
Once they were finished, Gonzales and Doopliss pulled out and they all flopped down. Completely exhausted. "Hah… Hah… That was… Incredible~" Koops panted.
"I agree!" Gonzales added. Just then, a voice was heard calling to them. A familiar voice.
"Mario? Koops? Gonzales?" They called. "Is anyone here?"
"Is that Goombella?" Asked Koops. Sitting up.
"Yeah, I think it is." Gonzales answered. However, Doopliss was nowhere to be found. As if he vanished from sight like the ghost he is. Shrugging, the two stood back up and walked off.
In a tree, Doopliss watched them walk away from the Fountain of Lust. The water's effects wearing off as quickly as it began. All he could do was chuckle mischievously as he heard Goombella scold them. He'd have to do this again sometime soon…
