You feel a massive stirring in your gut, and know almost instinctively that it's time. This thing's coming out, and it's coming out now!
You strain, pushing on every end and not knowing where, exactly, it's going to come out. Suddenly, you feel a rush of liquid at your rear as your "water" breaks, and give a silent thanks that it's coming out a hole that you've already got. Soon after, you feel an immense pain building as your asshole expands to let out the thing that's been incubating inside your, screaming in pain as it slowly pushes out. Moment by moment, the pain only gets worse, as the creature only seems to get bigger. As the agony reaches its climax, you could swear that you're giving birth to a full-sized elephant here. It's almost unbearable... and then it slowly sinks down, becoming less and less painful until at last you feel the final bits of the thing make its way out.
Exhausted, you collapse to the ground, barely mustering up the strength to turn and look at your "child". You immediately understand why it was so painful, as what you've just given birth to is the size of a full-grown human. It also seems to be completely female - its body is a mass of feminine curves, with a pair of large, gorgeous breasts atop its chest. Other parts of it, however, are very distinctly not human. Its face and head looks like that of an elephant, it has a ropey tail hanging from its voluptuous rear, and its feet are more round and elephantile than human. And, of course, this elephant woman is made entirely of latex, a fairly muted gray this time.
Looking at the strange woman, you find that she looks almost like your dream woman, except for the elephant parts. Even despite the animal bits and the fact that she came from you, you can't help but feel attracted to her, and find yourself already caught gaping at her beautiful curves and perfect (aside from, again, the elephant stuff) body.
