Once the vat is full!

Bryce grunted as his cum was pulled from his balls, which triggered whoever was face-fucking him to also cum, Bryce had **** but to swallow this person's load due to the ring gag in his mouth. Whoever was getting sucked off kept their cock in Bryce's mouth until they went soft and then pulled out, meanwhile, Bryce's prostate continued to be pounded by this mystery fucker which made Bryce cum again involuntarily.

Unbeknownst to Bryce, Coach Andrews (who had been the one getting sucked off) had told Nishki that one more load would fill up the vat that he was prepping for her, she smiled and started to speed up her thrusts, making Bryce whimper and moan around his gag, then it happened again, Bryce moaned as he came again, this one filling the vat full.

Bryce groaned as the vacuum was switched off, so that Coach Andrews could seal off and replace the vat that Nishki would take with her. Once Coach Andrews gave Nishki the news that her vat was being transported to her base of operations, she smiled as she started really ramping her pace up, what Nishki didn't know was that Coach Andrews had secretly been in contact with Dr Bluder who had then paid him double what he had paid Nishki to double cross the Futa Assassin.

The vat that had just been filled was actually heading straight to Dr Bluder, which coincidentally was where Nishki would be taken once Coach Andrews had taken away her cock and balls, leaving her as just another female **** of the evil Doctor. Coach Andrews had been told that Nishki was weakest after her orgasm and thus would be easy pickings.

Nishki started shaking as her balls tightened up before she buried her cock as deep as it would go, she moaned as her balls unloaded their precious cargo deep into Bryce's bowels, Nishki whimpered as she unleashed every last drop of her transformation-inducing seed, she'd never cum that hard before in her life and slumped over Bryce's back as the after-effects set in.

Coach Andrews smiled as he quickly grabbed some odorless KO **** that he'd prepped a cloth with and smothered an exhausted Nishki, his last words that she heard was: "Nothing personal, just business..." Coach Andrews then swallowed another Viagra before grabbing a condom from his desk drawer and rolling it down his cock, one of Dr Bluder's requests was that he not inseminate Nishki, the evil Doctor wanted to use Nishki's womb with some, alternate, spunk as an experiment.

Coach Andrews lined himself up before ramming his cock into Nishki's (now formerly) virgin pussy, not caring if he'd caused Nishki any pain as she was **** anyway. Nishki sleepily whimpered as her cock and balls slowly faded away forever, Coach Andrews fucked her hard for a good twenty minutes before pulling out and moving his cock to her gaping mouth, removing the rubber before jerking off into her wide open maw. Once he was recovered, he sent Dr Bluder a text saying her 'package' was ready for pick up.
