Mario entered the castle with his giant dick, bigger than him.
"Luigi!" he yelled through the hallways.
A goomba waddled around the corner and saw him. The goomba charged at Mario, and in defense Mario aimed his cock at the goomba like a javelin. They both charged at each other, and Mario cock-slapped the goomba out of existence, but sadly he had attracted more goombas and koopas.
"Let's-a go!" he said.
He grabbed a koopa and shoved it up his ass for more charisma points. He picked up the koopa and put it on the tip of his dick. The koopa desperately tried to hide in his shell, but it just couldn't. Mario raped all of the remaining troops, and wore the goombas on his feet, he loved the feeling of the goomba intestines in between his toes, and he went to see Bowser.
Mario walked down to the prison, looking for the kidnapped Luigi.
"Luigi! Where are yo-" He stopped, the scene in front of him too disgusting to continue.
Dozens of Italians were naked, with their stomachs cut open and entrails leaking out. Each one had a dozen cocks shoved down their throats, and cum coming out of their ears. The floor had an inch of blood and fluids coating them.
"w-wh-wh-w-m-why would Bowser do this to these people?!" Mario spat out weakly.
A massive arm lurched out of the corner, bashing Mario into the stone wall.
"You have no idea, do you?" Bowser said evily, "I have taken their power."
He stepped out of the darkness, his body mutated; he was enormous. Bowser pulled out Luigis's hat and put it on his head.
"You brother is gone," Bowser lunged at Mario, and they had an epic sword fight (with their penises) onto a platform over lava, "You won't get me this time!" Bowser shoved the hammer at the end of the platform in his dickhole and laughed. What will Mario do now?
There was an intense battle of dick-slaps. Each time Bowser would swing his fat, juicy cock around, it would make a large bang while breaking the sound barrier. Due to the power of the Viagra flower, Mario's dick was able to keep up with the sheer size and power of Bowser's throbbing reptilian meat machine.
"Bwahaha!" Bowser laughed as he blasted out cum like an oversized fire hose.
Mario was able to dodge the attack, but the rest of Bowser's subjects were not so lucky. They were instantly dead from the acidic seminal fluids. Mario then had to dodge another enormous dick-slap but this slap destroyed Bowser's castle entirely.
"Fuck!" Bowser cursed, "You Italian son of a sausage!"
Mario thought for sure he was screwed, until a strangely shaped toad emerged from the rubble *wink wink*.
"Mario!" the toad called, "Princess Peach wants to see you!"
But Mario saw his opportunity, and he took it. Mario suddenly sprinted towards the toad, when he laid his hands on it, he jammed it down hard on his cock and ejaculated all the Viagra power into the toad. The toad screamed, and Mario's dick protruded from its mouth. Jumping onto Bowser's dick, Mario jammed the toad down Bowser's urethra and sprinted away. When Bowser went to spray Mario with cum, he felt his cumhole being blocked! The flow of cum building up in pressure caused Bowser to squeal in pain.
"FUCK!" Bowser yelled, his voice like that of Anne Frank being taken away from the attic.
And with that, Bowser exploded with semen. Bits of cum and reptile were raining down from the sky, and Mario looked around desperately for Luigi. Luigi was no-where to be found. After what felt like hours, Mario searched for Luigi and found him in the middle of Bowser's exploded dick. He was wrapped tightly in Bowser's dicktip, shaking out of fear but not cold.
"Luigi!" Mario cried, shaking with happiness.
He had finally gotten his brother back.
