Riku lept out of the darkness portal, landing with a thud onto the floor of Master Yen Sid's tower. Twilight was falling over the mysterious world, and it was then that Riku realized that he was injured, badly. "Dammit!" He muttered under his breath, holding the wound in his arm with one hand. Suddenly, out of the sharp, darkly lined shadows that were cast around Master Yen Sid's tower, out came a small figure. Immediately, Riku knew who it was, and he was relieved. "Do you need some help, Riku?" King Mickey walked towards the boy, smiling, his big round ears casting large round shadows on the floor as he walked, like a giant pair of suspended breasts. Riku felt his pants grow a bit tighter as this realization came to him. He was a teenage boy, after all, and all of his company with the incredibly feminine Sora was not helping his lust at all. Of course, he could never fuck his best friend, that would just be wrong. Too many fanfics, too much fanart, too little pro to the bountiful con. So he resisted, but now, as the King knelt beside Riku, he felt his mind go fuzzy, like Mickey's round little mouse rump. "Riku, are you alright, ha-ho?" The King looked at Riku, his big eyes glowing in the fading light that was dimly cast into the room through the windows. "King Mickey..." Riku's lips hardly moved, and the next thing he knew, his lips were on Mickey's, tasting the mouse's tender flesh. The King recoiled at first in surprise, and then accepted the young teenage boy, his pink tongue reaching out and tenderly stroking Riku's. Riku pulled the King onto his lap, his small erection now a full-blown, grown-up sized boner. "Ho-ho! Riku, you're getting bigger..." The King looked down at Riku, batting his eyelashes, if mice even have eyelashes. Look, he was being seductive, okay. Anyways, Riku groaned, feeling his cock rip through the zipper in his jeans, increasingly massively in size and altogether girth. "Oh!" Mickey fell back as the now monstrous dick grew upwards, and began to mutate into the shape of a keyblade. "Ansem didn't just make my abilities with the darkness grow, King Mickey..." Riku plunged his Keyblade-Dick into King Mickey's tight mouse rump, tearing apart his sphincter muscles. The blood and fecal matter inside of Mickey's ass made Riku's cock feel slick and smooth, and so Riku began pounding the King. Mickey attempted to scream in pain, tears streaming from his great big cartoon eyes, falling on the floor like the small bits of muscle falling from Mickey's ass. Consumed with the pain and horror of his situation, Mickey began to vomit profusely, slipping onto his elbows in the slimy goo, his round little nose covered in puke. All the while, Riku's dick continued to grow, doubling, no, tripling in size. Soon, Riku tore apart Mickey's internal organs the stomach lining and small intestine caressing his key-cock and slithering around the empty hole he was fucking, like snakes in a hamster ball. Riku pushed farther and farther into Mickey's not-so-tight little rump, tearing apart his legs, ramming his gigantic dick forward until he felt the mouse's small, fragile heart burst on the head of his penis. Riku came, his white nectar streaming out of the rodent's mouth. With one final thrust, Mickey's body was torn apart, and Riku, now satisfied, laid back, his throbbing cock covered in blood and fecal matter smeared onto it. The deed was done. Riku had completed his mission.
