"Not so fast!" You says as you hurl a blue packet back towards Mary. It splatters directly across her chest as she grins proudly, even still. There is no concern in her eyes at all. You stop for only a moment to think of the implications of that before a tingling stirs your attention downward to your feet.
You can feel something stirring under your jeans that makes you itch like crazy, so you bend down and lift up the leg of your jeans to find that your modest hairy legs have sprouted even more hair. You watched it as it uncurled on your legs and became straight, as more and more hair continued to grow in.
"Crazy..." you murmur, as you look up from the floor to sneak a glance at Mary, who has removed her tank top entirely even though there are no apparent changes happening to her just yet. She seems relieved to have it off. "You uh, don't like the shirt huh?"
"Not my color." She winks. "You're gonna have a good one! Can't wait to see it!"
It? Did she mean the change or...?
She motions towards your legs laughing. There's definitely more going on than just growing more hair. The muscles in your legs have begun to ripple madly as they inflate. You feel a strong, uncomfortable pressure in your knees as they push and push against your body's configuration. You feel your knee cap disappear as a loud, upsetting "POP!" echoes through the cafeteria and your leg completely rearranges itself to be digitigrade. You realize now might be a good time to get out of your jeans before further changes potentially make it impossible, or painful.
You struggle onto your backside and begin fighting with your belt as you begin to feel your hips begin to stir, and crackle with the same odd tingling. You have to hurry!
Mary is watching you with great interest, as you look up and realize that her changes have definitely started as well. Her form has altered as she has gained some pudge. Not much, and it actually kind of compliments her form, but she also appears to have dwindled in height and stature slightly, judging by the sag that her bra now has. Her jeans are also looking a little...baggy? Even despite the slight weight she put on. If she was around 5'4'' before, she was probably only 5' now...maybe even less!
You feel your cock begin to stiffen as the thought of her change rushes through you. You watch her more actively now, struggling still, to get your jeans off at your hips have begun to expand into more animal like proportion, and you realize as you change that they are actually getting easier to get off. Odd. Then, at last the denim slides over your expanding hips and you struggle to get your jeans over your shoes.
Oh yeah....probably should've taken them off before.
You abandon your jeans around your ankles and remove your shoes only to find that they more or less slide right off with no difficulty!
You remove your socks to investigate why and see that your feet have been changing from human, to some sort of hoofed creature. The nail of your toes have surrounded the ball of your foot and you watch as it fills in black with the rest of your hoof.
"This is so weird!" You say, looking up at Mary, who is now definitely shorter than 5' and looks quite uncomfortable watching the ribs under her breasts push out one by one under her flesh. She's beginning to lose her wonderful figure, and her long legs have shortened and pudged up considerably. Her jeans are now bunched around her ankles and you can see that even her feet are loose in their shoes. She lifts one one foot up out of her shoe easily and you get a look at her perfectly manicured toes, painted black.
"I love it!" she breaths. Her arms begin to shorten as well, as some pudge flows into her face, somehow making her even cuter.
Her runs her hands down across her body to feel her changes, and you feel yourself now become painfully erect under your boxers (again something you should have taken off with your jeans). She reaches down and pops the button off her jeans and unzips herself. Despite her dwindling size, you can see that the pudge she had gained made it harder than she thought it would be. Strangely, her hips looked to be about the same size as before. Actually, you think, her whole torso aside from the changes to her rib cage is largely still the same in size.
Your mind clicks as you figure out what she's becoming!
"Mary you're a -"
"Satyr."
"What? No!" You say.
She laughs and moves closer, sliding her jeans down and exposing her red lace thong. "No. *You're* becoming a satyr."
You look down and realize that yes, she's right. Your hips are now fully animal and the hair you have been sprouting is now thick and light auburn. You realize now that it's fur. Your hooves have formed fully and your heel has extended back to punctuate your digitigrade stance. The only thing you can't see is your cock, which is concealed by your boxers.
Mary leans in close to your face, as your vision fills up with her beautiful features. You watch her hands move up past your face as she softly says "You have horns." She grabs them and gives them a light tug and become aware of the protrusions sticking out of your head. You reach up and brush her soft hand as she feels one, and to your surprise they're about 3 inches long!
They jut out from the top of your forehead and arch back into your hair, before twisting back and pointing straight up, like a wave! You give her a grin and say "How did I not notice that?"
Mary is very close to you. You can almost hear her changes finishing up, as her legs and arms grow smaller and stubbier. The smooth skin of her fingers retreated back into her hands, leaving her with cute, chubby and quite little fingers. It seems her change was to contract dwarfism. You must admit though, she pulls it off stunningly well, despite it not being what you tend to be into.
With Mary so close to your face, you can feel her hot breath on your lips as she inspects your face. You are just now realizing how erect you actually are. Most of her clothes have fallen off, save for her bra which only sags slightly in front of her still magnificent breasts. You can see her pert little nipples now, which stick out under her excitement. You look her straight up and down, and see her panties have also joined her jeans on the floor.
Her pussy is soft and shaven clean. It looks a little fuller than you'd expected it, but you suspected that was due to the packet and not her genes. She stands at only about 3'9'' now and you realize that while you've been sitting on the floor fighting with your pants and playing with your horns she has stretched her legs on the outside of your own.
She looks down at your boxers as your groin finally starts to get the tingle that you've become familiar with. It's changes are going to start now. Mary bends slightly, and even that little bit is enough for her pussy to brush up against the bulge under your boxers. You bite your lip as the combined sensations make your mind explode with pleasure. She leans more weight into you and you can feel the juices from her pussy soak in. She begins to run her pussy up and down along your bulge as you hold her into you.
Your mind flashes to Michelle as you begin to undo her bra, and finally as if a great weight is off her conscience, she pulls her face close to yours and kisses you passionately. Her lips pressed hot into yours, and you can feel the stickiness of her still fresh lipstick against yours, as she pushes her tongue into your mouth.
