The tingling becomes more and more intense as it spreads throughout your body. The afterglow of your orgasm begins to fade and change. Soon, you feel pins and needles everywhere from the neck down, underpinned by an admittedly pleasant, warm sensation. Slowly, you feel a sinking sensation building in your extremities.
You hold your hands up to examine them. Even though you're fairly sure you aren't moving your arms, your hands seem to be moving closer. You feel fear building as your mind scrambles to process what's going on. Under closer scrutiny, you realize that your arms in fact aren't moving. They're shrinking.
The fear turns to panic. You look up at Lascivia, who still wryly smiles down at you as she holds you, watching. “What's happening to me?!” you ask in alarm.
“Don't you already know?” She asks in mock confusion. “I'm taking the essence you're giving me. And boy, you're quite the giver indeed.”
Your arms and hands are losing their definition, slowly melting away into a vague fleshy mass. They now only extend maybe half the length away form your torso that they did moments ago. You feel Lascivia's skin sliding down the sides of your legs. Though you can't get a good look at them from the angle at which she holds you, you can wager a guess that they're undergoing a similar process.
“But-but they aren't changing. I feel like parts of me are just shrinking away. Shouldn't I be turning into latex or an animal or something?” You ask, darting your head back and forth to watch as your appendages keep reducing. They are now just nubs that extend several inches out form your shoulders.
“Ha, didn't I tell you that my gift was interesting? You see, I'm not feeding on you, you are. You're just offering up to me the essence that makes up your body. If I don't feed in the traditional manner, you get nothing in return unless I desire. And seeing what all you're presenting me, well, I'm eager to see the finished product without any interference. Maybe I'll be generous later, but I suppose we'll have to see, wont' we?” She laughs as your eyes widen in response. “Don't worry though. If I don't convert you by feeding, you get to remain one hundred percent human, at least whatever part of a human is left. But you won't die, you'll retain your consciousness and the faculties of whatever parts of you remain, and you won't have to worry about consuming other people. Humans can't absorb essence by themselves.”
You're still confused, but don't really stop to give her explanation much consideration, as you feel the changes in your arms and legs cease. Or rather, you feel your arms and legs cease, as there doesn't seem to be any trace of them left. On each side, your shoulders just stop partway along your collar, leaving your torso more or less rectangular. You want to try to move your arms and legs, but upon considering the attempt, you can't quite remember how. There isn't any phantom limb or sensation of something that ought to occupy the now empty space. It's like trying to imagine moving a tail – you can vaguely envision it, but the actual phenomenology escapes you. However, even though your extremities are finished, the changes aren't stopping.
The tingling in your torso intensifies. You vision begins to move, and you realize that you're moving closer to Lascivia's torso. You gaze down, seeing your stomach and chest starting to distort and lose definition in a similar fashion to arms earlier. Your head is slowly getting closer and closer to the latex conduit connecting your pelvis to that of the goddess that holds you. It continues pulsating as it pumps your essence into her.
“What-- how--” You struggle to even ask the question as you watch in horror, unable to do much more than wiggle at this point. “Is there even going to be anything left?”
Lascivia strokes your hair in a comforting manner. “Don't worry, you'll be okay. You didn't give up everything. Not quite. We're almost finished.”
You keep waiting for the changes to stop as your head is lowered closer and closer to her crotch. Soon, all you can see is red latex in front of you. The tingling begins to abate, and you struggle in an attempt to peer down and take stock of your situation, but you can't get a good look at anything. Suddenly, you feel a suction tugging in your neck, followed by a rubber POP as something comes free from beneath you. You feel air against skin you don't recognize. It feels like it's in your throat. Two red, latex hands take hold of your head on either side, and you're lifted up to meet Lascivia's gaze.
“Well, can you tell what's left?” You try to move your neck to look down, only to realize in terror that, as with your arms, you can't. As best as you can tell, all that's left of you is your head. You try to gulp, but swallowing feels strange. The woman cackles in glee.
“Judging by that expression, you can. I'll have you know, I had mercy and decided you deserved a little reward at the end. I find toys are so much more fun to tease when they can beg, so I gave you just enough to keep your voice. There's some slight side effects that I'm sure you won't mind.” She turned you sideways to support your head with one hand. With her other, she slowly traced a single finger down your chin, under your jaw, down to where your neck used to begin. Instead, you feel it touch the new flesh there, sending chills across your skin and producing a distinctive squeak of latex rubbing against latex. You would shudder if you could. The whole region is far more sensitive than anything you've experienced, and it's an agonizing mixture of teasing and pleasure as she drags the digit slowly across.
“Well, nothing to say?”
“I- I'm just trying to process what's happening. Why would you do this to me?”
She gasps in mock astonishment. “I did nothing of the sort. I just took what was offered, nothing more. But don't worry, you may find this form diverting.” With the last statement, she abruptly tosses you into the air. The world blurred around you and you immediately lost any sense of direction as you spun through the air. You're begrudgingly thankful that you can no longer vomit. Just as suddenly, a hand catches you with a clap, jarring you with the impact. The hand holds you by the back of the head, lowering you further and bringing you closer to Lascivia's flesh. Soon, you're staring at her mound inches from your face, where she holds you for a moment.
“I can certainly think of a few fun uses for you.” She lets the suggestion hangs in the air. “But maybe later. I'm not quite back in the mood just yet, though it rarely takes me long.” She brings up back up to eye level. She just stares, apparently waiting on something. “Well?”
“Well, what?” you ask hesitantly. She just raises an eyebrow in response. “Uh, what do you plan next, then?” She smiles, apparently getting what she wanted.
“Well...”
