Here is the second half of the two-parter as promised. Along with the other half of the story.

Massive. Bitchbreaker. Fuck no that won’t fit. All these words and more had been used to describe York’s incredibly endowment. Almost all orca bulls were large down there, but York was uniquely gifted. His cock when erect looked more like it belonged on a horse, or perhaps a centaur of myth. Unlike most equines though, this killer whale could go for hours.

Both were in the buff now, and whilst smiling for the camera Chrysanthos was doing their best to service the streamer. Up above there was a match being played, they thought it was a team FPS. Their brain struggled to think of which one whilst their hands and beak were nuzzling into the humongous throbbing organ in front of them. They lavished it with broad licks, caressing strokes and more, so much more. Was already far too thick to get both hands around, and they struggled to pull it down below the desk. This only made their heart race faster as the situation rapidly grew out of control.

With both arms more than hooked around the midsection, just below that “ring” the hourglass dolphin instead leaned in to where the orca’s loins were looming over the edge of his chair. Each was so big as to be near the size of a football, combined they were certainly larger. They could hear the rumbling, roiling contents inside as they nuzzled up against them. Fuck, the heat was something else too, or was it the taste as juices began to be poured forth, running along their back, drenched from blowhole to fluke.

“Getting a little close here chat. But the donations don’t lie. Looks like we’re going to have to change things up soon.” The deep voice from above was like a warning from a deity above.

A quick glance at the camera and Chrys tried to smile back, nervous as those swollen cum tanks churned besides their head. More donations could be heard from above. So they leaned back, letting their smooth arms slip over and squeeze around the whale’s pride. It was glorious and ever so wet as pre-juices came as freely as a running faucet. They leaned back to the point of nearly falling onto their back but their thick tail helped keep them steady.

“Oh shit, a super doner. Thanks, BigKittyWolf9X!”

Fuck. From this position, beneath the desk and prostrating belly up underneath the gamer above, the dolphin could get a good estimation of the size of things. They balked at the long, thick, black rod as it arced clearly over and even past their head. It seemed to be almost longer than the smaller cetacean’s torso. Another look back at the camera and a smile fuelled by as much nervous fear as excitement and impossible lust.
“And looks like we’ve reached out quota… time to change things up.” York grinned at the camera and then selected something on the stream deck whilst he pushed away from the desk with the dolphin in tow.

Chrysanthos was picked up like they weighed nothing. The little phin flailing a little as they were hoisted up to being on near chest level with the orca. They were facing the desk, the main cameras whilst they were pushed back against that leviathan that throbbed between both aquatics. A quick tying and hoisting of the dolphin’s hand to a fixture above and finally donning an RGB-lit collar were the finishing touches. York read out donors or something, it all blurred as all Chrysanthos could hear was that heartbeat, the inevitability of it all.
Timed seemed to skip a beat, or several, and before the dolphin knew it they were being pushed down on the colossal head. All the air left their lungs as York slowly but confidently pushed them until entry was made. In no time at all the orca had insert the first foot of his all-natural talent inside his co-host for tonight. Chrys did not know what expression they made, but it must have been something else judging by chat’s comments they spied from the corner of their watering eyes.

“ouch that’ll never feel normal again”

“Another one for the wall :D”

“FUCK YEAH! NOW FEED ‘EM THE REST BIG GUY!!!”

Despite the difference in size and strength York tried his best to make it comfortable. There had been plenty of lubricant, natural and otherwise, before the insertion. But whilst the mic was muted he kept asking how Chrys felt. It was difficult to describe even for the few words they could manage under ragged breath, but one thing was certain, they wanted all of it! And all of it they got.
“Like fucking hot silk!” York bellowed, grinning at the cam.

They could only take maybe half, though they would forever claim it was two thirds. Still, it was more than enough to rearrange their insides as York slowly picked up the pace, worked them out. Like an oncoming freight train steamed on ahead. Those strong hands kept perfect positioning for the viewers. He even made sure they got a good look at the phin’s own prehensile genitals a paltry size compared to the monster carving them out.

“Ten gifted subs? That’s another ten minutes. I’m sure you don’t want to disappoint.” York teased.
But all Chrys could hear for the longest time was their own heartbeat, or maybe that was York’s own with him so deep inside of them. Then an exultation from the orca and the feeling of him yet more stretching and filling out deep within. Chrys came with York, both climaxes cascading and washing over each other’s pleasures as dolphin jizz splattered over the desk whilst their yellow eyes rolled back with their stomach bulging out under load.

The sound of the squealing, clicking dolphin matched by the gushing, gurgling sounds coming from deep within were picked up by the mic. It covered up the sound of more and more donations that came flooding in. It looked like they could even beat the record if they kept the show up.
“HOLY SHIT I CAN’T BELIEVE THEY CAN TAKE THAT!”

“This is CGI right? AI?”

“please don’t stop”

York chuckled at the comments and gave the dolphin a quick kiss on the back of their bold head as they shivered and squirmed involuntarily on him. There was still more whale cum being packed deep inside. But this stream was far from over and seeing the viewer count the killer whale knew what he had to do next.

“Thanks for the hydrate reminder, chat. Going to need it. We’ll be going for another hour with this one.”
