Just as you feel like you can't hold it in anymore and are about to release, Kate's whole body tenses, and she grabs and squeezes you with both arms and legs. She shudders and lets out a final scream while her vagina tightens up and squeezes your cock. Your thrusting is briefly impeded by her ecstatic lurching, a blessing that just barely keeps you from cumming simultaneously with her. You immediately feel extremely clear headed as the intoxicating lust that just had you in its clutches seems to leave your body. Lascivia's various arms retract back towards her body, all but two sinking into and merging with her flesh, and she smiles as she watches you two in anticipation. You're still incredibly horny and on the brink of orgasm, but with your rational mind back in the driver's seat, it's much easier to resist. You collapse on top of Kate in exhaustion as you try to calm down and let your libidinous urges wane. Likewise, she sprawls out on her back, draping a single hoof in front of her eyes while you both lay there and breathe heavily.
You feel a strange tingling in your crotch, and you lift yourself to sit back up on your knees. As you pull back, though, there's an odd stretching and tingling sensation around your penis, and you never feel it lose contact with your partner. You look down only to find that where the latex copy of your genitals just was, there's now instead a deformed mass of flesh-colored latex connecting you and Kate at the pelvis. With a start, you try to pull further, but find that the connection resists the motion the more it's stretched. Meanwhile, the tingling is only intensifying.
As it gets stronger, you feel the tingle echoed in your face and ears, where it begins turning into a strange pressure in your sinuses. It keeps worsening, causing your eyes to water and you to close them in pain. You soon realize that the pressure seems to be coming from your trunk and ears pressing inwards on your head. You force yourself to crack an eye open and see Kate holding her head with both hooves now, eyes also closed as she scowls and lets out a pained moan. The pressure seems to be building to a point, and you're not sure whether you're going to pass out or your head is going to implode.
Something gives. Abruptly, the pressure is gone. All that's left is the pleasant tingle in your trunk and ears and a lingering, faint pulling sensation inwards. You feel the tip of your trunk moving up your torso, which confuses you as you didn't think you were moving it, but you did still doubt your control over it. However, when you feel the bottoms of your earlobes lift off your shoulders, you realize what's going on.
"H-Human, what's happening?" Kate asks, voice filled with panic. She's moved her hooves back away from her face, and you see her nose swelling and expanding slowly, while her ears begin to balloon outwards. You'd normally be a bit miffed at the reminder that she so readily accepted the nickname, but the thought barely crosses your mind as you try to find the words to answer her.
"I-I..." Nothing comes out. You know exactly what's going on. You slowly reach up to your head, running a hand up and down your trunk as you feel it retracting into your face. You move your other hand around to your ears, feeling and grabbing each one alternatively. You're amazed at how small they already are. Well, relatively, at least. You keep feeling in amazement as they shrink more and more. You can't help but feel a rush of excitement as you feel your human features returning, which is quickly overwhelmed by guilt as you can't help but remember that it's only because your curse was passed on to your new friend.
"No... Please no," you hear Kate beg as she begins to choke up. Her nose no longer looks remotely human as it expands outward into a cylindrical shape, wrinkling slightly as it grows inch by inch. Similarly, yours is finally beginning to seem less and less snout-like, gaining hints of humanity as it shrinks back to your face. Kate's ears continue stretching, losing some of their detail and changing shape as she gains the elephantine features that yours possessed moments ago. She idly paws at one with her left hoof, unable to get a solid feel of it, while her other hoof reaches up to cradle the bottom of her trunk, at which she gazes down in horror.
Soon, you look almost like a regular person, except with a grotesquely large schnoz and earlobes. You continue to feel at them in fascination as they finish shrinking back to fit your face. You run a finger down the outside of your left ear in relief and strain to cross your eyes to examine your nose for any hints of latex. Just in front of you, Kate sobs quietly as she tries with difficulty to probe of her new features. You feel your crotch suddenly release and pull back to you. You look down to find the latex cock and balls back to normal as if nothing had happened.
Upon seeing that you're freed, you stand up and continue obsessively rubbing your face. You could swear your nose feels a bit different than you remembered, but you aren't sure if that's just because you haven't felt it in so long. You decide to ponder it later and instead attempt to offer Kate some sort of comfort or assurance, but you don't get the chance as Lascivia clears her throat and approaches again.
"My, I was hoping for a show, and I was treated with a spectacle," she cooed approvingly. She strides between you and Kate and bends down over her. "Here you go, a treat for doing such a good job," she said with a slight hint of tease as she presses a hand between Kate's legs. When she pulled it back, you could briefly catch a glimpse of Kate's human vagina back in place of the latex one. Lascivia turns around towards you, and you anticipate her repeating the process. But instead, she reaches both arms out towards you and grabs you by the shoulders, lifting you a foot off the ground.
"Come, I'm sure she needs a bit of time to herself to adjust to what just happened. Besides," she says with a breathy sigh, "I'm properly worked up now. And you didn't even get to cum, now did you?" The last part took on a sickeningly saccharine tone, as if she was talking to a child or pet. She pulls you against her chest in an embrace, nuzzling your face between her breasts, as she continues carrying you several yards further down the path. "Mmmm. Yes, you won my little challenge, and winners deserve a prize. I'm sure you'll enjoy it."
Any attempts you make to answer are muffled by her obscenely large bosom, and after a few tries, you resign yourself to just hang there limply.
"I think that's about as much waiting as I can take," she declares as she comes to a stop. She pulls you back away from her torso, and you wait for her to put you back down, but instead, two new arms extend from her sides, just beneath the two she already had. One reaches out towards your crotch, beginning to caress and tease your penis as the other reaches down towards her own sex. She bites her lips as she just gazes at you for a few seconds before closing her eyes and pulling you in for a kiss. Her luscious lips completely envelop yours. Your heart races and you pant heavily through your nose, drawing in the smell of her. Her scent is musky and raw, but impossibly alluring, as if her body excreted pure pheromones. You hungrily drink it in, and the intoxicating lust you felt earlier returns in force to take an even stronger hold on your thoughts and senses. Your member is completely solid and throbbing. Lascivia's hand seems to begin secreting some kind of lubrication as it clutches your shaft tighter, moving from a faint brush to a proper stroking motion.
Her tongue presses against your lips and you open to allow it to ease its way just into your mouth. You move yours to meet it, the tips just lightly flicking against each other at first. The two of you ease in deeper and playfully twiddle your tongues around one another for awhile before she pulls hers back and breaks off the kiss. Her strokes are becoming less frequent, even though her hand only seems to accelerate. With each pass your cock feels more and more sensitive to her touch. She presses your brows together, her head faintly turning side to side as she nuzzles her nose against yours, and looks deeply into your eyes. "I think we're about ready," she whispers.
She extends you away from herself slightly and begins lowering you. You glance down as her hand leaves your cock and are astonished to see that it now extends almost two feet, covered in the liquid latex that you mistook for lube moments ago. You suppose this is what she was waiting on. She positions it against her wet slit as her two extra arms reach down to your legs for support. Still standing but with her legs now parted around you, she suddenly pulls you up, thrusting you inside her with surprising force, and you gasp at the stimulation. She moans and squeezes your face against her chest as she begins moving your hips up and down, thrusting you in and out of her.
You'll admit you aren't the most experienced guy out there, but you've never felt anything remotely close to this. You feel like a toy as she has her way with you, doing all you can to move your hands up and down her torso from her curvy hips to her impressive breasts. She shifts you to the right, proffering a stiff nipple to you. You acquiesce and begin teasing it with your lips and tongue, occasionally rubbing your cheeks, your nose, your whole face against it before returning to your oral ministrations. She takes in a sharp breath and lets out a long, throaty moan in approval. You reach your left hand up to stimulate her right breast as well. One of her hands moves up from your back to grab a fist full of your hair, the tips of her fingers lightly scratching your scalp as she presses your face more firmly against her chest.
You feel a fifth arm begin to expand from her torso and creep its way down between you to begin fondling her clit. You jump as you feel something tickle the back of your thigh. Soon, her tail is brushing against the bottom of your balls as it makes its way between the base of your buttocks and presses its tip lightly against your asshole. Rather than entering, it begins to tease and massage you, and your eyes roll back into your head as you're overwhelmed by all that's going on.
Amazed that you lasted even this long, you feel your pleasure rising to a head. The pressure builds in your crotch and your member tenses and flexes. Lascivia's chest rises and falls more and more rapidly against your face as her coos and moans intensify. You feel yourself approach the edge.
"That's it. That's it! Give it to me. You know you want to. Release your essence inside me!" the goddess yells as you give in to the pleasure. Your body explodes with pure bliss as you release load after load. "Yes! Ooooohhhohoho yeeessssssss." Lascivia utters in ecstasy, giggling as she cums in unison. As your spurts slow, her thrusts do likewise, and soon she's holding you tightly against her as you both gasp heavily.
"Mmmmhmmhmmm. Don't you feel better now?" She says with a smile as she slowly eases your face back from her chest to look down at you. All you can manage is to meet her gaze as you recover your breath. Her eyes take on a wicked shine "Now, we get to determine the rest of your prize. I can't wait to see what you gave me."
The implication snaps you out of your daze. You feel a familiar tingling begin in your crotch again, and you look down in horror.
"Did you forget? Right now, I'm absorbing all the delicious essence you've offered me. I'm sure we'll find out what your body decided it didn't need any moment now. Perhaps, if it tickles my fancy, I'll give you a little something in return. But who knows? I might find you sexier as is. I guess you'll just have to wait and see!" She giggled again as she teased you. She continued purring and stroking your hair, obviously getting off on your fear and squirming. Then, you felt the tingling begin to spread.
