You begin to walk away, grateful that your waddle isn't as pronounced as it once was, although your udder, now squished up against your stomach by your jeans, has an effect on your gait and sloshes with every step.
After a few steps, you wince. A couple of the nipples on the udder have become pinched against your jeans, rubbing up painfully against the denim as you move. You stop and reach down, squishing up against the latex sac, which squeaks audibly as you draw out the two teats, letting them hang out in the air with their, uh... companions? Sisters? Either way, it looks pretty embarrassing.
A small rustle is heard behind you and you turn around. The cow-patterned egg sits on the ground where it has always been, but peering closely, you could have sworn it quivered. You stare at it for a few more seconds, then notice it shake a bit more intensely. It *is* moving!
You step back, but a sudden twinge against your udder causes you to stop again. You look down, expecting one of your nipples to have fallen into trouble again, but all four of them hang out over your jeans freely. You feel another twinge followed by a faint gurgle, and gasp as you realize your jeans are slowly being pushed out and down as more pink, latex flesh spills over their top. Your udder is expanding!
You fumble to free your udder from the constrictive pain of your jeans, finally managing to pull them down. Now unsupported, the swelling pink sac weighs heavily between your legs. You reach down and try to pick it up, but it squeaks and sloshes clumsily against your hands; you can feel the flow of liquid within it as it continues to swell.
Realizing that you better move while you still can, you try to turn, but the udder and your nervousness concealed the fact that your pants are currently around your ankles. You fall backward and land on your butt, your udder wobbling and rippling in front of you like a pink waterbed. You strain against your growth, trying to stand, but your udder has grown massive and heavy and you can't find your center of gravity as it swells against your legs, pushing them apart.
Supporting yourself with one hand, you can only press into the now-shiny, swollen sac as its growth begins to slow. You push in hard, hearing a squeak as you feel a wave of liquid pass from one side to the other. You feel four heavy slaps against the other side of your udder as the wave hits it, realizing your nipples must've grown, too.
You weren't able to make it far from the egg. You turn your head to look at it, but it's currently sitting still, almost watching you as if to say, "What? You think I did something?"
