Keep experimenting--maybe a taur shape?

"I think I don't want to go downstairs like this juuuust yet..." you said with a nervous chuckle, brushing blonde hair from your face. You could feel the imaginary eyes staring at your backside all afternoon and that wasn't the kind of attention you were ready for. It's hard to blend in when a part of you suddenly stood out...

You started to gather up all the clothes, realizing that the ways you bent over or knelt down felt so different with these legs. Your natural muscle memory to lean down and scoop up clothes from the floor had you grasping at air an inch above the fabric... but you quickly compensated, and gathered a pile of clothes before stepping out of the lab.

You desperately hoped no one else was on this floor, because you realized you were just hugging two sets of discarded clothes to you, having been so used to wearing nothing in that office, and even feeling like you were wearing a pair of pants, in a sense, that you realized your pants were in fact another layer of skin, with a very strange sight of a face between your legs. Chloe burst out into giggles as she felt your panic, when the adrenaline hit that made you nearly bolt back into the conference room.

"It's fine, it's fine!" Chloe urged. "Head to lab 2, that's my space."

You began to walk, a little shaky as your gait was too short for what your legs were capable of, so instead of confident strides with swaying hips, you were taking baby steps along the hallway. "If we do this, can you make it so Zoe can talk again? So she's not just left out of these decisions?"

"Fine, fine... she'll just agree with whatever, anyway. Zoe, as I said, is in love with you. I'm... well, I'm coming around to the idea, let's say I have a healthy interest in you as of right now, I mostly just want to get in on some fun. But she really would do anything to gain your affection, and so you'll find there's not a lot she'd say no to, as long as it allowed her to stay close to, or on, you."

You blushed again, wondering why Zoe is so enamored with you, even after things you'd heard or facts you'd gathered. It still just seemed so strange, this beautiful bodysuit being so willing to give up any semblance of independence so you might move her around all day... not just because it was her nature, but because she cared about you.

Eventually you entered the lab with one of the keycards dangling from your clothes pile, setting the clothes down on the nearby couch, admiring the space briefly with the mix of lab to one side and living space to the other. An enviable arrangement for a work-life balance...

You stopped when you felt a tingling in your legs, as Chloe glanced upward. "Now it's my lab, my rules, so you better brace yourself because you're going to experience something very new!"

You grabbed the back of the couch, just in time as your eyes went wide. You could feel your body growing... well, not your body, technically, Zoe's form was expanding out from you! But you could strangely sense it all... you looked behind you, as your legs grew... more legs! Very quickly, your spine had extended backwards, into a second waist, set of hips, and identical legs to what you currently had.

You let go of the couch, taking a cautious step back. You didn't really understand how to move four legs, but Chloe seemed to step in and fill in the blanks, moving your rear pair while you still guided your front pair. You stepped in sync, until you were in front of a nearby mirror on one of the pillars in the lab space, gasping as you saw your new human-taur reflection.

"Why stop there?" Chloe grinned between your legs. Clearly she wasn't done with just making you an average humantaur. You watched as your rear legs grew in size, gaining extra muscle tone and width at the hips, creating legs that looked more fit for an Amazonian goddess than anything! The waist connected to your back also seemed to gain the Amazon treatment, extending further until you seemed to have a whole warrior goddess body bent over behind you, including a sizable pair of breasts dangling down! Instead of being connected at the waist, it was more like your front legs were at this taur-form's shoulders...

Your front legs saw the most change. Curiously, you still retained shapely hips and generally your legs looked like legs, not nearly as stocky or powerful as your hind legs but still toned. The knees seemed to invert, though... bending backwards instead of forward. And the feet... those changed drastically, toes elongating while the foot itself shrank somewhat--you were looking down at a pair of hands, almost! These new fingers and thumbs rested on the ground somewhat like you were wearing heels.

Shocked was an understatement for what you were looking at. The shape of the body was so bizarre from the norm, even though from the front you still looked quite a bit like a normal human if you discount the inverted knees and hand-feet, but the powerful other half of your taur body seemed entirely out of place!

That was, until Chloe took over movements of the lower body, and stood you up. You were technically already standing, on four legs. But when she lifted you up further onto just the two back legs, you realize what she had done. You gained considerable height, essentially having massive, muscular legs that still retained that Amazonian femininity supporting what looked like a matching upper body up to the shoulders of that form--and from those shoulders, your far more diminutive waist, upper body, and head sat atop it, looking down. It was sort of like you were giving yourself a piggyback ride, and your head nearly grazed the ceiling with your new stance. What felt like legs in your taur-form seemed more like arms now, although the movement still sort of felt strange in general--when you had been quadrupedal, it was like those middle limbs had been able to push their shoulders together to create your front hips, but now that you were standing upright, they seemed to stretch outward so those arms rested at your side.

"Neat, huh? The body's all yours, by the way--it'll move how you want. I call this the 'modulataur'! Since you can alternate between bipedal and quadrupedal without any effort." Chloe beamed, her face still at your waist even after all those changes. From her perspective, her face was about where a normal head might be for the Amazonian part of your form.

Cautiously, slowly, you began to move those middle-limbs, the arm-legs that seemed so strange to you at first. It was kind of felt like you were moving your legs still, but with so much more range of motion than you'd expect... when you tried to wiggle your toes, those fingers on the new, somewhat elongated hands wiggled instead. These new hands came up to rest on the truly massive breasts that hung off this body below your normal waist, feeling their incredible firmness and roundness, like two massive watermelons dangling from your body and yet it seemed somewhat well-proportioned to the larger frame you possessed from the waist down.

"This is... I mean, it's stunning!" You had to admit it, there was something incredibly enticing about your strange but powerful new shape. The strength of the warrior-like body tapered into your more average form at the top, creating this potential for both strength and sturdiness while still maintaining a normal-ish silhouette when you lowered back down, at least from the very front. You did just that, bringing your body back to it's 'quadrupedal mode' as Chloe might think of it, your mid-limb's shoulders collapsing toward themselves to create the shape of hips and legs. You tested some walking, unsure at first, but Chloe again helped, letting you guide the body around but ensuring your steps with your new leg configuration never tripped you up. It was amazing how easily you could move this bulky body affixed to your back...

"Okay, Chloe, this one is just weird!" A voice suddenly piped up, causing you to glance backward. You didn't say that, nor did Chloe... you leaned your upper body down, glancing between the gap of your front arm-legs, and back to the Amazonian hind-legs, where a new face had emerged at Chloe's design. You spread the rear legs a little to get a better look at Zoe's face that was staring up at you. She didn't seem angry, but the suddenness of appearing at the back end of a taur was probably a little jarring...
