"Grrr.... Fine!! I'll prove my ass can take that little dick of yours, but just this one time so don't get used to it dweeb!" Bowser snarls.
"Hmm... Youa really think so?" Mario taunts.
"Shut up! I know what you're doing, but I've made up my mind already so enough of this teasing bullshit! I won't even feel anything so it doesn't even matter to me" He obstinately lies. Mario's erect cock's well-above-average despite his rather short physique, and not even the likes of a large reptilian beast could look at it without feeling a shiver down his spine. But Bowser isn't about to admit defeat; he lays back on the bed and, after a brief pause of reluctance, spreads his legs to reveal his juicy red hole. The sensation of his exposed ass snaps him back to reality and forces him to realize he's letting himself get fucked by his own mortal enemy; the thought of it gives him a visibly red face.
But before Bowser could reassess the situation, he receives Mario's face straight into his ass, getting slightly pricked by his mustache. Mario immediately begins to pressing his starving tongue against Bowser's hole, enchanted by its manly smell. Bowser quickly holds his massive hands against his mouth fearing that if he was to open it he'd undeniably moan from delight. He's unsure why Mario chose to lick his ass before fucking it, but although he could never admit it, it relieves Bowser knowing he'll be loosened up.
Perhaps my magnum opus. Might finish might not; C'est la vie
