Every time this vampiric bimbo drains her Jock GF, said Jock only gets bigger and more muscular, meaning more blood for the bimbo to drink. And somehow, she never notices even as the additional blood causes her to pile on weight and become a nearly helpless fatty.
It's like the stimulation from being drained, or perhaps side effects of the bite and suction, make it so that instead of turning into another vampire, or something along those lines, the Jock GF gains even more muscle mass, taking another step towards becoming the absolutely perfect bride that the vampiric bimbo desires.
Her canine teeth are sharp and big, like proper vampire fangs, but they're still not compared to the pillowy, plump, shiny, black colored lips that give even more allure to the already beautiful vampire's face. They really pair the bimbo look together, without even bringing her body into consideration.
She was always a beacon of sexual attraction, even if sometimes her mind lacked perception of her own body. Something that would prove to be crucial to her not understanding just how much hotter she was becoming in the Jock GF's eyes. The towering, growing, muscular woman, only becoming stronger every night, with every bite, isn't the only one looking sexier to their partner. With all the excessive blood consumption that this bimbo vampire is allowed to have thanks to the Jock GF's unusually high amount of blood, her body had gone from curvy to properly fat, and eventually started becoming more and more pronouncedly MASSIVE, with rolls for days and nights, flabby arms, an enormous amount of cleavage that one could get lost in, thick, tubby legs, a couch like ass, and of course, a titanic gut that just couldn't help but always be hungry (or thirsty, in this case, maybe?). Thankfully, her Jock GF's transformation, with her impossibly powerful, large arms, with boulder like biceps, along with immense core strength and an overall insane muscle capacity and stamina alike, thanks to her blood amount increasing, made it so that she could still lift and carry the vampire if she wanted, and help her move around if she became too fat to waddle, let alone fly. She might become completely immobile soon.
With one becoming more insatiable than ever, and their attractions to each other growing alongside their bodies, it was hard to see a future where that wouldn't happen~ <3
