As it would happen, your second favorite fetish just happens to be bimbos with huge dick, or futanari bimbos. You definitely were not fully aware of this, yet it also didn't shock you that much either. While you don't often look for that specifically, when you have stumbled upon it, it usually had gotten you pretty turned on. There was just something about girls with massive dicks in front of their pussies that worked for you.
As the fetish was realized in your mind, thanks to the fairy's magic, you froze, knowing full well what was about to happen to you. Apparently Sarah also got wind of it too, as she started to laugh. Not in a cruel or demeaning way, but just because of the irony that the guy who wanted a harem of girls would now become a girl himself. And a girl with an even larger dick than his current size to boot.
It was actually Sarah who changes first, as her shape slightly adjusts. Her straps specifically become better shaped to fit around a woman's curves. In addition, a portion of them now widened into a shape that now somewhat resembled the cups of a bra as a pat also now crossed over your front, connecting both straps together.
What worried you about this, was how much space there was between your chest and the insides of the cups. It was no small amount, as you imagined you could easily fit two full sized watermelons in the space. If it were not for Sarah resting her chin on top your head to hold her in place, she would have tilted backwards as well because of the newly added additional space had not yet been filled. But that was soon to change.
The fist change to your body is your waist. Feeling everything in that space squish together as your waistline narrowes down significantly, nearly makes you puke. But luckily that feeling only lasts for a moment, and then goes away. You are quite surprised with how just this alone already is making your hips and ass appear much larger by comparison.
Then, as if to only prove that point, they actually begin to swell outwards as you hips flair outwards and you get a perfect, feminine ass which is outlined perfectly by your now too tight pants. Every curve is pressing into the once loose fabric, stretching it out as your pants begin to adjust as well. The material turns black and thins a lot, bordering on being see through even. And it doesn't stop their. All down your legs, your pants begin hugging tightly to every single nook and cranny as they slowly turn the same color and thickness. Finally, they actually blend with your socks, becoming a dark, sheer pair of pantyhose.
Next, most of your legs slim down slightly then lengthen a few inches. But your thighs actually widen and expand just a bit instead. Your feet slim down as well, before your shoes reshape into a pair of black platform stiletto thigh high boots with a 4 inch heel. The boots fit snuggly around your calves and the lower part of your thighs, and made your already great paur of legs even sexier.
With your lower half nearly completely female, you knew what was next. You feel a slit open up behind your balls as a cavity opens up inside your gut, forming your new pussy and womb. And almost instantly you can feel yourself beginning to get wet as this process is turning you on so much.
You watch as your balls start swelling, becoming the size of baseballs. You are shocked to find that your pantyhose actually have not only not torn, but have actually reshaped to fit around them perfectly.
Now it is time for the main event. Your dick slowly starts to expand. As it grows, your pantyhose also reshape to now form a sleeve of sorts around it too. Slowly but surely, your dick grows and widens until it is as thick as your forearm and practically scraping your chin with the tip.
You shift your weight a bit on your heels and watch as your cock wobbles around a bit. You are actually quite intrigued by it and absentmindedly open your mouth and start leaning your head forwards as if to stick the tip of it inside before catching yourself. Your erection finally stops wobbling after this due to becoming fully hardened by your actions. Your pussy is now even leaking a small bit too.
The changes make their way further up your body, finally reaching your chest. You resign yourself as you watch your new breasts fill in the entire empty space and then some, as Sarah now holds them tightly in place, almost like a corset, which gives you some pretty amazing looking cleavage. You can't help but bounce your heels a bit and enjoy both watching as well as feeling them jiggle about as best they can within Sarah's strap cups.
It is actually Sarah who next changes as the new joining strap seperates momentarily and pulls your dick in between your tits before reattaching itself together and then presses down on your shaft, ensuring it not only is held tight to your stomach and chest, but also cannot be move much, except for the last several inches which have just enough freedom of movement to be able to slip into your mouth if you wanted.
The issue here is that you are essentially trapped into giving yourself an endless titty fuck. You take a few cautious steps forwards and sure enough, you can feel your titties rubbing against your shaft as they bounce and jiggle with each step.
The changes quickly reshape your shirt into a slim black mini dress which is just bairly low enough to cover your ass while standing. Your dick of course runs up the front and is visibly pressed into the fabric before the fabric splits apart at the rather deep V neck opening. The straps are loosly hanging on your upper arms too, meaning the dress is both tight enough, and shaped well enough to not fall off with them not holding it up.
Your arms slim down and become soft and feminine as all hair from your body besides your head, eyelashes and eyebrows is removed. Your remaining hair turns a whitish blonde color and falls down your back, becoming slightly wavy in the process until it settles at a length which is just bairly above your ass. A light amount of makeup appears on your face as its features quickly contort and shift until you are left with an unquestionably feminine face.
You wish you had a mirror. But seeing as how you clearly don't, you opt for the next best thing. You look up at Sarah and see her eyes widen and her eyebrows raise up in surprise.
"Wow.... Wow. I-I am speechless. You look... You look hot. Like holy fuck you are hot. I'm actually rather jealous here. But im also so damn happy that your my hot as fuck girlfriend." Sarah's face is flushed too, and she looks as if she is trying her best to keep herself together.
"What's up? Hehe..! Oh shit, is this my voice?! I even have a hot voice!" You say with a gleeful smile that you just can't seem to get rid of. Your body feels so light and bubbly now too. Everything just feels great. Even your balls which are slapping against your thighs as you rock back and fourth in your heels with excitement, are feeling all tingly and good.
"Why are you all smiley now?" Asks Sarah who also starts to grin.
"I don't know. I just feel like, super excited for some reason. Like, now I'm just all hot and sexy. Plus I have like, THE biggest dick ever! Ahh, I kinda am also like, wondering how it like, is gonna feel to suck on such an enormous coc-". You quickly cover your mouth with both of your small, feminine hands as you only just now realize what you are saying in such a happy, bimbo-y tone.
You take a few deep breaths and recollect yourself. "Sorry about that Sarah. I dunno what came over me just then, but I am like, sooooooo much better now. Ah, I mean, I am totes fine. No damn it! Aghhh! What I'm like, trying to say is that I'm like, actually not a bimbo. There, I finally managed to say it. Yay!" You say with a little cheer and a sigh of relief.
Sarah is smirking back at you though. Doing her upmost best to not just break out in laughter. After getting a hold of herself she opens her mouth to reply. "You know, you just used the word "like" twice in that sentence."
"OMG, did I really?!"
Sarah nods, unable to speak because opening her mouth at the point would just lead to her laughing.
"Fuck!!!! Did I really? I like, totes didn't even catch it. Uuuggghhh... What'ev, I'm still like, totally just as smart as before. So like, I guess it fine. But like, OMG this is like, so annoying." You say as you give a bit of a frustrated stomp.
This finally is too much for Sarah and she just breaks out laughing at you. Her laughing is making you grin too. "It's not funny!" You say as you also start laughing.
You begin to walk again, only now no longer carring as much about how your body is forced to act somewhat like a bimbo. You just keep swaying your sexy hips with each and every step you take as your cock is rubbed by your gigantic jiggling boobies. You are happy that at least you only just are forced to act like a bimbo, and are not actually one through and through. You also are quite looking forward to fucking Sarah tonight and are wondering who the next harem member will be.
