She births Mythical creatures.

While Tom looks on in amazement, Sarah bears down with another orgasmic moan. With her huge, centaur ass squatted down, her bulging mare pussy is only a couple of feet off the ground. With a blissful cry, a spray of sexual fluids, and another clench of her inner muscles, she pushes, and their offspring is half out of her. A few seconds later, Sarah lets out another cry as an orgasm rips through her, and then the child wriggles out of her.

Only moments after their offspring lands on the soft grass, it's already climbing unsteadily onto its hooves. Somewhat disbelieving, Tom looks at it, and quietly asks, "Is that... Is that a unicorn?"

Still squatting in place, squeezing more milk from her full breasts, and shivering from her recent orgasm, Sarah looks over her shoulder. With a foggy look in her eyes, she glances around before locating the fruit of her loins. She says, "Ahh, another one?" She shivers as another aftershock passes through her body. "Yes, I thought I could feel hooves kicking around inside me," she continues, before giggling, "I'm getting quite good at guessing what I'm carrying now, actually."

As Tom watches, the horned creature manages to get its hooves under it, and then gives itself a shake. He watches in amazement as the birthing fluids and pieces of grass stuck to the marvelous creature simply slough right off its gleaming white coat. Much more sure on its hooves now, the unicorn trots towards its mother, intent on the set of mare-like breasts between her rear legs, which are steadily leaking milk from their dark nipples.

Before the mythical beast can latch on, however, Sarah lets out another wail of sexual bliss, as her huge centaur pussy bulges out again. She whinnies in orgasm, shudders running through her body, as her horse ass bobs up and down. Each jiggle of her massive, round, centauress booty sends another thrill of arousal through Tom's body, before he shakes his head, and focuses on what his wife is about birth now.

Again, Sarah orgasms, shudders, pushes, and births. Her husband is amazed at how quickly it occurs, with her birthing in only minutes, before focusing on their newest child. It is... a deer? Or, perhaps an elk?

As he watches, the deer-like creature also scrambles up, giving Tom a better look at it. The first thing he notices that suggest it isn't some ordinary deer is the fact that it seems to have ivy growing around, and out of, its body. That it already has horns starting to grow out of its head, with flowers blooming on them, is also a dead giveaway that this is no mundane creature. Some sort of Forest Spirit? he wonders. As the two Mythical creatures move towards their mother, Sarah lets out a deeply content sigh, before standing straight on her hooves. She ponderously turns the vast bulk of her centaur body, gives Tom a loving look, and then turns her attention towards her children. With a slight frown on her face, she looks at them, and says, "Hmm, more animals. Oh well."

Still recovering from the shock of what he just observed, Tom goes over and stands by his wife, who takes a moment to lie down on a soft patch of grass. Once she settles down properly, the two creatures she just spawned quickly trot around to her rear and latch onto the swollen, mare-like teats between her rear legs.

Sarah lets out a pleased sigh as the two beasts begin nursing from her, but otherwise seems to ignore them. Turning her attention to her husband, she smiles at him contently and pulls him into a hug, squishing her huge milky tits against his chest. With peaceful look on her face, she tells him, "I really do enjoy birthing the larger creatures. It's nice when there are more, smaller ones, but it doesn't quite match up to the feeling of something really stretching me out."

Grinning at her in amazement, Tom says, "Yes. That... that really was amazing." He considers how to bring up the issue of what they should actually do with the two creatures straight out of legend, before his wife speaks again.

"Still, I wish that..." Sarah says, and sighs, a slight hint of disappointment on her face, before continuing, "I just wish I could give you real children. People, real babies, instead of creatures."

As she looks slightly forlorn, Tom pulls her human torso into an embrace, and gently kisses her. Lovingly, he says to her, "I really don't mind, dear. Besides, I'm sure we'll eventually figure out some way for you to have human, or maybe centaur babies."

Reassured by his words, Sarah leans in and begins passionately kissing her husband. Distracted by her hot lips against his own, Tom sets aside the issue of what to do with their fantastic offspring.

After several minutes of this, she lets out a grunt, and pulls away from her husband. Glancing over her shoulder towards the rear of her mare-like lower body, Sarah says, "Ahh, looks like they're done," before clambering to her hooves. Tom steps aside so he can see what she's talking about, before slightly goggling in surprise.

In the few minutes that the two mythical beasts had been nursing, they had rapidly grown! The Unicorn was now full grown, a beautifully graceful creature. Its shimmering white coat and opalescent horn seemed to emanate purity, in some indescribable way. The deer-like Forest Spirit had grown even more prodigiously, taller than its mother by several feet even before you counted its massive antlers. It was also shrouded over with vibrantly green vines and leaves, and flowers bloomed on its antlers in riotous colors. The two creatures look at the couple who had given them life, before simultaneously wheeling about and leaping off into the woods in different directions.

Tom watches in awe as the two magical creatures he sired disappear into the forest. What a day, he thinks.

While he's watching the two marvelous creatures disappear from sight, Sarah gives another contented sigh. After a few minutes of the Saunders standing in companionable silence, she begins to shuffle back and forth on her hooves. She speaks up, "Tom, dear? Do you feel like breeding me again?" As she says this, her tail begins waving back and forth, fanning more centauress musk around the clearing.

In response, Tom can't help but laugh, and pull her human half down for another kiss.
