"...the person who would be the one you're most attracted towards. Be they a real person, or someone who if they were real, would be the one. The person each of you will become will ultimately be human, but may have a varied amount of variety in exactly what form they take. Some will be taller, some shorter, some of you may change race, while some of you may change into someone you know," explains the Professor.
You begin to panic in your seat, as you reluctantly are forced to breathe in the gas. As you do you begin to feel yourself changing. And the more gas you breathe in, the further and faster your transformation gets.
It starts with your hair, which grows out long, reaching just past your ass, and turns an off white color. This is followed by your fingers slimming down, with your hands following suit until they are dainty and feminine. You watch as small bits of hair begin falling down before your eyes as your eyebrows thin, becoming neatly trimmed. Then your eye lashes lengthen and fill out a bit more. Your nose and mouth shrink, while your eyes get a little larger and turn a bright green color, which is a stark contrast to your former brown colored eyes.
As the rest of your facial features work themselves out, you feel the process reach your neck, giving you a bit more length, while removing your adam's apple and thinning your neck. This leads to your shoulders being pulled closer together, while turning more feminine in appearance. Your arms become slender and hairless, as they the progress connects up to your new shoulders and continues downwards.
As you expect, next is the removal of all of your chest hair, then the development and growth of your new breasts. You find yourself in a bit of an predicament as your new boobs swell larger than you had anticipated, and begin pushing against your tshirt. Besides straining the fabric against their shape and size, your boobs also have lifted the bottom of your shirt up enough to show off your waist and midriff just in time for the changes to start affecting them.
Your body slims down, following a curvy hourglass figure, with a sexy narrow waist and a much wider set of hips. You seem to have also gained a lightly tone yet sexy set of abs, which are just barely are visible. You give your new waist a feel with your newly feminized hands and feel just how awesome it is. Everything is just so perfectly suited for your exact interests!
You reach behind you and squish your fingers into your new cute bubble butt, and feel a little bit of arousal stir up in doing so. 'Am I getting turned on just by touching my ass?' You question to yourself. You continue to grope your wonderful ass and confirm that you indeed are getting horny from doing so.
This only draws your focus to your erection, as it begins receding back inside of you. Just your dick though as for some reason, your balls actually grow just a tad larger instead. This confuses you for a moment, until they begin doing the same as your dick and pull back inside your now almost fully formed pussy, making 2 small plop sounds as each one enters your still widening slit.
With your pussy fully formed, you can't call yourself a man anymore. No, you are undoubtedly a woman now. And are an unquestionably beautiful one at that. While your legs become hairless, then transform to become long and slender, you begin to wonder what will you do now that you are a woman. You feel your feet undergo their change and then nothing.
'It appears that my transformation is over with' you think to yourself. Just as you think that, you feel your head and lower back suddenly become overwhelmed with discomfort. You actually let out a feminine groan because of it. However then your eyes start hurting, and finally you lose your sight altogether.
You cry out in pain as you feel your body continue changing, though not like before where everything was painless. Your eyes feel as if they are burning and the side and top of your head hurts a lot too. Even your ass is in pain as you blindly fall out of your chair and onto the floor where you begin groaning louder as the discomfort grows even more.
The Professor makes his way over and begins taking notes as he observes you, but you don't even know he is there. By now, your new, sexy body is covered in sweat and a few other students begin to take notice of your apparent unusual reaction and slowly start to crowd around you out of interest.
After about a minute passes with you in total darkness, the pain in your eyes leaves and is seemingly transfered directly to your ears, as they begin to ache and you immediately go deaf after hearing a loud "pop".
This forces you to open your eyes, and you notice that everything is far brighter than it had been a moment ago. It is as if someone turned all the lights back on, which did not seem to be the case. As you look around you, a few of the students cover their mouths in disbelief, while the Professor actually leans in to get a closer look. You can see their mouths moving, but of course have no idea what is actually being said by any of them now that you are deaf.
You wipe your eyes clear of tears and struggle through your pounding headache to face the teacher and try and get some kind of explanation out of him. He does nothing though, and you are left to fend for yourself. But, like with your eyes, your hearing returns in about a minute while the pain and discomfort relocate. Now that you can hear again, you try asking what is happening. You also hear your new voice for the first time, and if it were not for what is happening to your body right now, you likely would be gushing over your new sexy sounding voice.
Finally the pain leaves your body and you are able to focus long enough to ask again about what is going on with your body. The Professor simply points to something behind you, so you frustratingly check over your shoulder. To your complete shock, you find a long, white cat tail swishing behind you. Then one of the guys takes out a hand mirror from the purse he is holding for some reason and hands it to you.
You look into the mirror at the reflection of an unquestionably feminine and beautiful woman's face. However, instead of normal eyes, your eyes have turned into green eyes only with long vertical slits instead of the normal round shape for pupils. In other words, you now have a human hybrid form of cat eyes. Though if you didn't still have the white parts of your eyes, then you would say they are fully formed cat eyes and not hybrid ones.
Following that, you look higher on your reflection and confirm that while the sides of your head are now absent of ears, the top of it now has a pair of white fur covered triangles sticking up through your identically colored white hair. In other words, you now have cat ears.
You look up and hand the mirror back to the guy and finally notice the obvious. That he is for some reason wearing a tight fitting crop top and a skirt. You feel like an idiot for only now realizing that every one of the guys surrounding you are more than likely the girls in your class that were affected by the gas and became their ideal man.
However none of the other students are owners of non-human body parts like you, which is very concerning. One of the girls offers you a hand, which you take. However, she begins struggling to pull you up to your feet, which greatly surprises her. 'She probably was a strong guy before tramsforming into such a small and frail girl' you guess in your head. Then one of the new guys takes over for her and easily pulls you up to your feet with an equal amount of surprise in their eyes as the girl had. "Woah, your like, super light" he says in a surprised tone, but then the Professor corrects him. "It's more like you are now much stronger than before. Just like how she is not as strong as she use to be" he says with a nod in the direction of the small girl.
He then returns his focus back to you. "I must admit, this is a first for me. In all of the tests so far, we've never had a student develop animalistic traits. Not even once. So I am admittedly at a bit of a loss for what to do about this. Nor do I know why it happened in the first place. So for now, I would like to place you under observation, just in case something else happens. But for now, I don't see a need to inconvenience you with a visit to the lab right away. Just please stop by my office sometime in the near future for an examination. And you may leave class early if you wish today. I am sure you do not wish to be anywhere but someplace comfortable right about now."
You nod and go to collect your things when one of the new guys approaches you. "Hey, can we talk for a minute in private?" You agree and exit the lecture hall, while he volunteers to help you with your things as an excuse for him to leave the lecture. You both end up going into a bathroom together at his insistence, and once inside, he finally begins explaining himself.
"Can we swap clothes please? My stuff should be close to your sizes, and your clothes seem to be more my new size now. But I worry that if this goes on too much longer, my clothes will either be ruined or break as they are too tight for me now" he says.
You look at him and nod, as you are already tired of holding up your extremely loose shorts too. Plus, if you are wearing his clothing, then not only will you have a bra to keep your boobs from bouncing around so much, but his sweater dress will not feel nearly as weird with your tail as your shorts do.
You both enter adjacent stalls and begin handing each other clothing. He seems to get dressed pretty fast, and is already changed in a matter of seconds, but you are struggling. He then opens your stall and walks inside, joining you. You, being not even half clothed, are feeling incredibly awkward now. But he tells you to turn around and hold your hair out of the way. You do as instructed and he helps you into the bra, while explaining a few different ways of putting one on.
You thank him, and then exit the stall once you are fully dressed. Amazingly, you and him were perfect sizes for each other's new body. Though even if that is the case, learning to walk in 4 inch thigh high boots will be quite a challenge. However, he offers to help you out until you get use to it as thanks for not only getting him out of class, but also for agreeing to swap clothes. It takes you a few minutes of practice before you get the general hang of walking in heels. But now that you are able to not fall or stumble ever other step, the two of you begin heading back to your dorm room.
