No matter how badly she wanted to join forever with this incredible woman, Joanna simply couldn't bring herself to do it. No matter how much of Katrina's bright soul became part of her own, the luster would always be diminished. The girl she was wrapped around so tightly, now enveloping from head to toe, simply had to remain her own person, her own separate being. But there was no reason that she couldn't still partake in this bliss.
With the whole of Katrina's body now subsumed within Joanna's slimy shell, a small part of her detatched, splitting off from the rest of the black mass. It felt like a part of her being cut away, and brought with it the first sensation of pain she'd felt since her conversion. She forced herself through the agony, however, knowing it was for a good cause. Indeed, she could already sense the excitement from Katrina as the detatched bit of slime, now disconnected from Joanna's mind, embedded itself within Katrina's chest.
The young woman moaned into her as the substance did its work, heat flushing through her like never before. She had begun in an excessively sensitive area, Katrina's small but supple breasts; their shape was already offering less resistance to the constriction of Joanna's form as the slime diffused into them. A vibration farther down Katrina's body stimulated an even more private area, causing further cries and flashes of heat that only drove the material within her to spread even faster.
Every degree by which Katrina's temperature raised only seemed to heighten the excitement in Joanna's own body. The arousal wasn't merely limited to a few spots as it had been when she was human - it now rippled out, carried along every cell of her amorphous form. The entirety of her existence was an egregious zone, pulsing ever faster as she felt the girl within her give way to a blissful creature of the same design as her. Neither Katrina's mind nor body offered resistance, welcoming the pleasure and happiness of the slime to consume her.
When the last little bit of her flesh had finally been converted, the newly-created slime-girl vibrated wildly, her whole body exploding and pulsating with the pleasure of a orgasm shared by every tiny speck of her existence. The burst of joy caused Joanna to experience her own intense reaction, as the effort she'd put into keeping a form shaped like Katrina's old body could no longer be maintained. Such trivial things as a humanoid form fell by the wayside as they quite literally melted into each other, the pools of their respective forms swirling in a puddle of pure bliss.
She laid there for hours, not caring about a thing in the world save for the woman she was so helplessly entwined with. Movement only came as she felt Katrina stirring, part of her pulling away to regain a human-like shape; her own body quickly followed, eager to have eyes with which to view the other woman once more. Torsos quickly formed, with arms and heads, leaning in opposite directions away from where the rest of them still lay puddled as their upper bodys assumed shapes identical to how they'd looked as human beings.
Katrina's nude form as as wonderful as she would've expected. So pretty, so delicate, like an angel with an expression of pure happiness plastered on her face. Looking down, she found that their lower bodies seemed to simply vanish into the pile of sludge that was their entwined forms. She stared with fascination at the way they interacted; Katrina's melted form appeared to be silver, rather than the shiny black of Joanna's body, metallic in texture instead of being smooth and rubbery. The liquid of their lower bodies was combined in alluring swirls, like two different paints mixed together yet never quite able to combine.
There was one connection that was made: every feeling each of them had was flowing between them freely. A cascade of emotions - shock, surprise, joy, excitement, arousal, and quite a few dirty thoughts that managed to slip through. Thanks, especially. Their gazes met, and Joanna didn't need to hear a single word from Katrina to know how thankful she was for this gift, how much she adored what her body had become, all the bliss that had been denied to her for so long now something her whole body was immersed in. Still, she was driven to vocalize something, even as tears of joy ran down her cheeks.
"We have to share this." Her voice was shaky, quivering with excitement. "The whole world, everybody... they need to experience this."
