Before the alien who was once known as the 12th Doctor brought Humans from Earth to Galifrey 2 Galifrey 2 was a small Earth like planet that had no life. No birds, no Mammals, no fish, no reptiles, no insects, this is because Galifrey 2 was originally a Moon that was terraformed by an unknown alien race.
The terraforming process took 1,000 years and when it was done these aliens boarded their ship and set a course for their new home. At some point during their voyage their ship was invaded by the Weeping Angel's and the alien crew was killed. These were the same Weeping Angel's that the god of time defeated by tricking them into looking at each other using his cloacking and transportation devices.
Yes the technology 12 uses makes him invincible and his infinite regenerations makes him virtually Immortal but he's still just 1 being. He can't defend Galifrey 2 from invaders and raise the Human children aboard his ship at the same time so he created several robots ( with female voices ). These robots raise the Human children, name them, teach them how to speak English, check their DNA and let them know who they're related to ( to avoid incest and inbreeding).
12 is happy, knowing that the Human race living on Galifrey 2 will exist forever and proving that a species that is not divided by politics, economics and religions is truely free. A species that is not divided by languages, cultures and traditions is truely happy,.
The problem with Immortality is that you're going to spend it alone, Human life is so short and watching the people you love grow old and die is painful. Fortunately for 12 he has met Immortals during his many adventures and he invited one of these Immortals to live on Galifrey 2.
Captain Jack Harkness is a Human from Earths future, he was killed by a Dalek but brought back to life by the entity known as Bad Wolf. This ressurection made Jack a fixed point in time, no matter how many times he dies he'll always come back to life, it was his Immortality that allowed him to kill Abadon ( the Son of Satan ).
Captain Jack is multisexual ( Human males and females and alien males and females ) so unlike 12 who sees the Humans of Galifrey 2 as his children Jack has no problem joining the Humans of Galifrey 2 during their orgies and gang bangs. Equipped with the same technology 12 uses Captain Jack helps 12 defend Galifrey 2 from invaders but when he's not doing that he spends his time with the Humans of Galifrey 2.
Completely naked and eating from a food tree and drinking fron the fresh water pond he notices the sweet smell from the gel the Humans on Galifrey 2 use to remove their body hair. They were given the gel several days ago but their bodies and breath still smell sweet. Choosing a beautiful Women he passionately kisses her, rubbing his hands up and down her back before grabbing her big round ass they get the attention of several males and females.
Jack is a happy Man, he's had orgies before but nothing like this, laying on the ground he's fucking the Woman he chose in missionary position. Another Women is behind him massaging his back with one hand and grabbing his ass with her other hand. Pulling his rock hard cock out of the Woman he was fucking he gets the Woman that was massaging his back into doggy style position and slides his cock into her wet pussy and fucks her hard, fast and deep.
The sweet smells and all those hands touching him as he fucks multiple Women is incredible. He finishes in the mouth of one Woman and then sits on the ground to catch his breath but is immediately pushed on his back by another Woman who then sits on his face. As he eats her pussy he can feel another Women lick his balls and other Women massaging his body and legs.
This massive orgy lasts all night, the sights and sounds of sucking, fucking, grunting, moaning and screaming as they orgasim is amazing and knowing that this is going to happen to him over and over again for all eternity makes Jack so happy. As the Sun rises is starts raining, the rain puts out the large camp fires that light up the night. Now that the massive orgy is finished the Humans use the rain to wash themselves.
While the Humans wait for the rain to stop Jack makes his way back to the ship and after drying off he gets dressed. 12 asks him how he likes the paradise he created for the Humans of Galifrey 2? Jack absolutely loves it, they have a long conversation and this is when Jack learns that it was the death of his companion Clara that made 12 stop calling himself the Doctor.
The next day Jack helps 12 give the gel to the Humans and Jack is told by several Women that they can't wait for the next orgy. After giving the gel to the Humans Jack and 12 easily stop and invasion attempt by the Sontorans, Daleks and Cybermen.
After defeating these invaders Jack strips naked and joins the Humans for another orgy. Sweet smelling, hairless adult bodies touching, rubbing, sucking and fucking each other over and over again. After having his cock sucked by 2 Women Jack gets another Women in missionary position and starts to fuck her hard, fast and deep. Kissing another Woman while another Woman massages his back Jack keeps switching Women and fucking them in different positions until he cums in the ass of a Woman and then eats the pussy of another Woman.
Protected by two invincible Immortals not even gods and devils dare invade Galifrey 2.
