Ty having just left his foster parents house for a walk decided to take a look inside the old abandoned house that was the only one left standing on deer lane despite being told not to enter it by everyone else. Ty then opens the front door and walks inside, it was very nice looking and clean as though the house itself kept it's own upkeep. He closed the front door, and afterward he saw the door to the basement open itself, as if the house wanted to show him something, he entered the basement door and it closed and bolted itself. He now has no choice but to continue forward, entering the enormous basement there is a cocoon in the far right corner.
Going over to the cocoon Ty had begun inspecting it when an umbilical cord shot from the bottom rear of the cocoon, it was two inches thick and ten feet long, Ty was helpless to stop the lightning quick cord from piercing his navel, it attached it's own blood vessels to Ty's and fused to his belly, then volcanically hot blood rushed into his system causing him to feel sleepy immediately, he started to fall over but tentacles came out of the back of the cocoon and lifted him into itself, afterward it closed and sealed itself instantly and filled with amniotic fluid completely in three seconds.
Afterward a different kind of cord came out behind Ty's head toward the base of his skull, and extending a sharp three inch needle shoved it into Ty's brain forming a neurological connection, Ty's consciousness awoke in a type of dream plane, and a different consciousness asked, What kind of anthro do you want to be?, a circular set of dream holograms appeared in front of him, but they all were hermaphrodites with huge breasts, deep cavernous pussies, that has ovaries the size of an apple, and with wombs capable of unbirthing even pregnant humans , having very long two inch thick cocks, with huge slightly hanging watermelon sized testicles, but he was particularly attracted to the deer, I want the deer herm please Ty said, The other consciousness said selection accepted, this process will take nine months, the house above will be locked down and vegetation will grow up around it to protect your gestation.
That's fine Ty said, my foster parents won't miss me but they'll be surprised when I show up again. Affirmative, your consciousness will now return to your own body though the brain cord will remain attached to acclimate your body to walking on hooves, your new clothing will be tailored to accommodate your horns, and you will retain your omnivorous diet, as much as my creator did but he died before he could use this cocoon, he died of a disease that ate him alive from the inside just after he completed his work. Your new body will inherit all of his wishes as he would have had if he hadn't died beforehand. Alright then, I think I'll call you Tracy and my new name shall be Tyra, new designations accepted, from now on instead of A.I. 01, I shall be called Tracy, and you will be called Tyra.
I'll see you in nine months Tracy, Tyra said, with that she fell asleep to not wake again until her cocoons water breaks.
9 Months Later
It has been nine months since Tyra went missing, and a whole forest had grown around the house, Tyra's cocoon had swelled greatly with her new form, and two tentacles caressing her massive three inch thick placenta unfurled from it and pierced the placenta and cocoon, and ripped both open instantly causing Tyra's amniotic fluid to drain rapidly, as Tyra awoke from gestational slumber, she stood and felt the umbilical cord that gave her her new form and name and caressed it with love, Tyra then said thank you my friend, the umbilical cord shivered in appreciation, and separating itself from her navel, and blood vessels, it allowed Tyra to pull it and it's needle out where she dropped it to the floor.
Tyra walked out of her cocoon and, exited the house the vegetation vanishing rapidly upon the turning of the doorknob, and Tyra having dressed in the clothing provided by Tracy.
She walked back to her parents house and saw that her foster mother was eight months pregnant, Tyra was six feet four inches tall and she greeted her foster parents who yelled TY! they both hugged and kissed her, though Tyra was rather gentle with her pregnant foster mother, my name is Tyra now she said, as she began french kissing Jane, and rubbing her breasts butt and belly, as this happened Jane's breasts grew to match Tyra's and Tyra had slipped off her lower garments revealing her huge deer cock, Mark blushed seeing that his foster daughter now had a bigger cock than him, Tyra picked Jane up and carried her to the master bedroom and put her on the bed on her belly and told her to stay, she went into the master bathroom and pointing her cock over the tub pissed in it claiming it as her territory, she went out to Jane and found her being obedient, and grabbing her butt pushed her full length into Jane's vagina slapping her giant balls to Jane's quadruplet belly, causing her to moan loudly at the volcanic heat of her new mates heavy nutsack.
Tyra plowed Jane's pussy again and again, making her moan and cum with every slap of that heaving baby making sludge sack to her baby filled bump on her gut, Jane could do nothing but moan drool and leak breast milk as her new mate took her utterly, Tyra came crying out, I'M CUMMING MY LOVE!, Jane suddenly felt that volcanic heat surge into her fat occupied baby maker, Tyra's cock then swelled at the base and she used the new knot to tie with Jane. Tyra came in her new mates womb for three hours and changed the babies father and species, she pulled out of Jane and put her tip in Jane's mouth having her swallow the rest. She became a pregnant anthro doe in seconds. Jane fell asleep while Tyra went and unbirthed and umbilical corded Mark and Dustin before going to sleep beside Jane in the master bedroom.
