The large and buff shark was trying to break free of his bonds. His thick tail attempting to trash about and his rock hard cock flopping around, smacking to his rock hard abs and thighs. All this, was just a part of a much bigger picture as everyone's eyes were watching how a lean and lithe alien boy, was pounding his gargantuan fuckmeat right down the shark's throat. Those lips were stretched into a wide O around the boy's dick, his cheeks and throat bulging outwards each time the alien boy crams his fat dick balls deep into the larger male's gullet.
Foamy and slimy mixture of spit and precum was constantly bubbling out from over the shark's lips, running down his chin, from where it dribbles down to the middle of the stage into a slowly growing puddle. Not to mention completely coating the hung alien boy's crotch as it smacks into the shark's face, beating the big, buff fag's chin with those bloated alien balls and getting ready to unload all that thick and sloppy ball snot right down the squirming shark's throat.
As if the amount of precum Duke was already forced to guzzle down, the climax was enough to make Duke gag and retch from how much cum there was. The potent alien cock slop was soon enough squirting out of the shark's nostrils, pouring over his lips like a waterfall and pouring into the shark's stomach, which was starting to swell and distend. Bit by bit, those abs nearly disappear from sight as the large shark keeps swallowing, feeling his growing stomach nudging his dick downwards, just before he spurts his own load across the stage below.
By the time the alien boy finally withdraws his dick from Duke's throat, the shark is just a sweaty, panting mess and as he looks around, he could already see the audience around them, beating their own oversized cocks as they await for their turn to fuck the shark fag's throat raw.
Duke Nauticus by me.
