Starts during the summer after the Marauders, Lily, Bellatrix, Alice, and Frank are in their 6th year and Narcissa is in her 5th.  Andromeda has graduated and married Ted, and both her and Sirius have been disowned.  Voldemort is still amassing his influence and followers and has yet to prove himself a threat in the eyes of the Ministry. 

It's been years since the last goblin rebellion, and most wizards and witches only see the goblins as a group of greedy bankers.  The intelligent ones remember that even though it's been years since the last war, the goblins are just as militant as always.  But only the goblins know of their third most defining trait: their insatiable lust.  The reason no one sees any female goblins is because they are almost always doing one thing: calming the raging lust of their male counterparts.  The only exceptions are those that are too young, too, old, or are pregnant.  However, in the last few decades, the number of male goblins has been increasing faster than the number of ready females, resulting in goblins spending longer and longer without sex.

One day, a lobby guard, lets call him Bob, who was well past his due for a trip to the breeding chambers keeps finding his eyes resting on various witches that came into Gringotts.  Eventually Bellatrix Black (Or another sexy racist pureblood witch) enters and demands an escort to her account manager.  Bob is assigned this job, and spends the trip trying to tune out the woman's snide comments and unspoken insults to his people even as his eyes keep being drawn to her body. It's after one particularly nasty comment that the frustrated goblin wonders just what the consequences would be if he knocked the witches wand out of her hand, bent her over, and ravaged her ass.  Fortunately or unfortunately, they arrive at the account managers office and Bob excuses himself.  However, his desire to fuck the witch senseless stays in his head, and Bob has an idea.  An somewhat crazy idea that would help sooth the raging lust of his brethren while gaining double agents for a new rebellion in the most delicious and insulting way.  The guard consults with his commander, and soon finds himself before the Goblin King to present his idea: spiriting away young, influential witches, train them into obedient sluts, and then sending them back out as their secret agents.  While the King is initially hesitant, his own frustration is quick to supply images of some of the hot racist pureblood women he had met with on their knees and sucking his cock like an eager slut.  The King agreed, and assigned a group of goblins under the Bob's command to this task, under the condition that they work alone until they prove they can pull it off, so if they are caught the King can claim they had gone rogue.  And thus begins the goblins rise to power.

That was the premise of the story, an I also have a skeleton of a plot as well.

Part 1

The Beginning

These Arcs cover the enthrallment of members of the generation of witches before canon proper.

Arc 1

The Black Sisters

1 or 2 Chapters

Soon after the team was formed, Bob was on guard duty again, though this time he was also scouting for good targets.  And he hit the jackpot.  Bellatrix Black, the one who caused him to come up with the plan, and her younger sister Narcissa walked in, and with a runic array near his helmet's head, he was able to hear their conversation.  Apparently the Black family home needed their wards updated which would take a couple of weeks, and the Black head and his brother, the sisters father, were needed to supervise. The Head's wife and heir had gone to visit her family, but the two sisters decided to stay in Diagon Alley and shop, among other things.  Bob signaled his team and the teller the sisters were approaching, and when the girls were directed to a hall that the teller claimed would lead to the cart that would take them to their vault.  Bob escorted them into the seemingly deserted hall and shut the door behind them.  Immediately, anti-magic wards flared to life and the two sisters were quickly knocked unconscious.  The Black sisters would wake up deep within Gringotts completely naked save for a magic suppressing collar around each of their necks and surround by a group of leering naked goblins.  While Narcissa is to stunned to put up much resistance, Bellatrix fights the goblins until Bob finally throws her down and makes good on his fantasy.  By the time the Black house ward updates are complete two weeks later, the girls have submitted, and serve as eager sluts for the goblins, Bellatrix with the same passion as when she served Voldemort in another life.  After the girls return home to keep up the appearance that nothing happened, Bob remembers that the Blacks used to have another, elder sister. Digging through the files, he finds that she was disowned for marrying a muggleborn.  While Ted Tonks wasn't a pureblood, he had a high (for a muggleborn) position in the Ministry and Andromeda was becoming a very successful lawyer.  So when Ted left on a business trip, Gringotts called upon Andromeda for business.  Upon arrival, she was lead to a room that upon entering caused her to freeze.  In front of her was a group of goblins, naked and surrounding a pair of witches who were eagerly sucking and jerking their cocks.  She grabbed her wand only to hesitate when she recognized the women as her sisters.  The goblin that escorted her there knocked it away and dragged her over to the orgy, where Bellatrix and Narcissa helped welcome their sister into the fold.

His own cock growing hard, the King asks Alice about her plans and she tells him about her plan to meet Lily.  Alice also informs them that while Lily is a muggleborn, the heir of the Potters had been after her for years, making her a perfect target.  The King orders her to lure Lily there, where he decides to break this witch himself.  A week later when James arrives at Hogwarts, he is pleasantly surprised to find that Lily seems to have finally given in to his advances, never suspecting she was ordered to get close to him by her new masters.
