As the doe lies in the grass she begins to feel a very warm throbbing sensation throughout her body. It pulls and aches all over her ungulate form, making her distinctly uncomfortable. Deep inside of her body, changes begin to occur. Her bone and tissue growth begins to accelerate dramatically. Her very living organs that sustain her life begin to alter and move within her. Most remarkable is her brain, which increases subtly in capacity and begins to grow smarter and self-aware.
The sensations tugging at her internally become a yawning tingling sensation that pulls at her flesh. She is somewhat confused over what she is feeling, having never felt it before and having nothing to compare it to. She gets to her feet, shaking violently. Her stomachs churn and her heart starts to beat alarmingly fast as she breaks out into a warm sweat.
Thump-thump-thump-thump. Her blood boils and her heart pumps it faster through her veins. She has built up sufficiently inside and her processes and living flesh are in readiness. Her body is primed for the full transformation.
A blinding painful snap at the base of her spine makes her bleat in pain. She rears up on her hind legs in fear and thumps to the grass again, still managing to stand despite her wobbly legs which are too weak to support her own weight.
The sickeningly strong tingling becomes horrible burning pain. There is nothing she can do to escape it. She helplessly falls onto her side, writhing in agony and crying out in distress. Another terrible crackle from her hindquarters and her back legs begin to thicken up with meat and grow longer. At the same time, her thighs pull themselves toward her rear, pushing her tail and anus up.
The doe is now frothing at the mouth and near unconsciousness from the trauma racking her body. She can concentrate on nothing but the searing pain. Her torso grows larger and her rib cage expands greatly, pushing her guts around inside. She manages to open her eyes long enough to find herself lying on her back, and feebly raises her front legs up to her vision to find the hooves pulling apart and contorting into five-fingered hands. Now abject fear overrides the incredible pain of her transformation. She’s terrified of what’s happening to her and cannot look away.
Now her front legs grow and her joints snap and reconfigure. Her reshaping torso yanks her vagina up from her rump and sets it between her legs. All but two of her teats shrink away to nothingness. The remaining pair climbs higher to her chest and her breasts begin to inflate until she has a B bust. Her neck pulls her head back onto her body and her spine permanently uprights her stance. She is now in her final anthro configuration. The pain subsides immensely, leaving her pulse quick and her lungs sharply gasping for breath.
She is numb all over and still in terrible pain, but the process is nearly complete. She feels it starting to slow down and instinctively knows that it is almost through. Only minor things need to complete now. Her thick deer hair becomes fluffier and less coarse, retaining all the beautiful markings of a whitetail. Her insides and biological makeup alter subtly. She now has all the internal organs and functions of a female human being. Her thought processes begin to pick up and her brain suddenly floods with the things that she now inexplicably knows. Her heart finally slows down to beat normally, her breathing becomes less desperate, and the pain at last fades away entirely.
The last changes to her person are the most important. As her mind finishes its expansion to fully sentient intelligence, she finds that her vision becomes more highly defined. The fear of what’s happened becomes amazement as a shock of rainbow saturates her worldview.
She is a fully anthropomorphic six-foot tall female deer.
