*Authors note*
As the original ending of this story was far darker than many of you wished for, I decided to create an alternate version. There may be more stories exploring this timeline in the future.
Less than 10 minutes after Hanna and Grace had arrived at Master's house, the girls were sitting side by side on the bed, VR headsets wrapped around their heads and dildos plunging into each of their pussies. As a reward for their ultimate submission, Master allowed them to watch the spirals for as long as they liked. Hanna was so grateful that Master was as kind and generous as he was.
She was in her own little world of bliss, the comfortable familiarity of the spinning objects and pulsating colours filling her vision and melting away all of her thoughts. The uncertainty and conflict at her parent's house had been deeply unpleasant. Hanna didn't want to think about that, she only wanted to submit to the spirals. It was so easy to submit, she thought as another orgasm cascaded over her.

"We are going on a trip." Master declared the next morning, explaining that a helicopter would be coming to pick them up in the evening. "I need you both to trust me, no matter what happens. We are going to a very dangerous place. I need you to keep the men we will meet there happy and focused on you two. You will be the stars of the show, and I know you won't let me down. Obey your Master, and all will be fine. Am I understood?" he asked sternly to a chorus of "Yes Master." from Hanna and Grace.
For the rest of the day, Master allowed the girls to lounge by the pool. Between swimming and sunbathing, Hanna and Grace found themselves returning to the spirals regularly. This was the relaxing life their submission guaranteed, Hanna thought to herself as she stretched out on the couch, staring intently at her phone. This life was so simple.
Hanna and Grace were only to bring the items Master had prepared on their beds. The girls went off to the rooms that Master had assigned them the evening before, each finding the same skin-tight fishnet bodysuit and a short black skirt that barely covered their asses. Hanna got dressed quickly, remembering to also ensure her "Mindless Slave" collar was securely affixed around her neck. She looked at herself in the mirror, her modest cleavage partially shrouded but on full display. She marvelled at how fit she was, and at how much better she felt now that she was under Master's control.
Returning to Master, Hanna couldn't help but appreciate how good Grace looked, her tits barely concealed by the mesh. Master had already packed their headsets and other gear, and led both girls out onto the lawn. They clearly would not be staying long or wearing any clothes the entire time - none of which bothered Hanna. It wasn't her place to ask questions or worry.
The helicopter came swooping in over the trees, landing in the clearing in front of the house. The three boarded quickly, the pilots paying no mind to the two half-naked girls as they took off and headed out over the water. Hanna couldn't help but stare out the window as they flew for the next 30 minutes. When she did glance at Master, she noticed that he looked nervous, and that he couldn't stop fidgeting. He was wearing a tuxedo and bowtie. well tailored and expensive looking, she thought he looked good. She had no idea where they were going, but was excited to be on a new adventure.
As the sun began to dip below the horizon, the helicopter began to descend. Only a few moments before landing did Hanna notice the massive yacht they were approaching. She had never seen a yacht this big - another reminder of the mundane life she had led before submitting to Master. Every single day was more exciting than the year of her life before she met Master, all because she was a good slave and obeyed.
A young man in a tuxedo greeted them as they disembarked. He shook Master's hand and gestured for Master to follow him. The boy paid no attention to either girl, and Hanna soon understood why. As they followed him to the front of the ship, they walked onto the main deck, which was crowded with at least a hundred people talking over the background music. Most were dressed for a black tie event, the men all in expensive, well-tailored formal wear and some of the women in elaborate gowns.
However, Hanna quickly noticed that roughly half of the women present were in various states of lingerie or bondage gear. One girl was on all fours, a gag in her mouth and wearing a collar with a leash being held by the man standing next to her. Another was wearing a skimpy plaid skirt and mostly open blouse. A girl serving drinks wore nothing at all, save for a ball gag and collar. Any notion of looking out of place would have been immediately quelled, had Hanna been capable of such thoughts anymore.
The man led Master and his two sluts through the main deck and up the stairs. They entered a large room with four men sitting in leather lounge chairs on one end. Master walked up to the men, gesturing for the girls to follow. When he reached the middle of the room, he turned to them and said: "Empty, and on your knees." Hanna and Grace obeyed immediately, falling to their knees on either side of Master.
"Dr. Simmons," said one of the men in the chairs. "We have been looking forward to your presentation. The summary you sent us looks extremely promising." Hanna stared blankly ahead, her mind wonderfully calm. Master had started speaking, explaining some complicated science that Hanna would not have understood even if she wasn't a mindless, empty slave.
"The findings you have been sharing have us intrigued, but I'm sure as you are aware, a practical demonstration will be required." one of the men said, looking hungrily at Hanna.
"Of course, I would not have come all this way if I did not intend to show you the results of your investments first hand." Master responded. "Repeat". He said to no one in particular.
"It feels good to obey. I am an empty, mindless slave."
"It feels good to obey. I am an empty, mindless fucktoy." each girl said in unison.
He looked at each girl, before motioning for them both to stand. "They are perfectly obedient and perfectly trained." Master said, a smile on his face. He walked behind Hanna, wrapping a hand around her throat. "They will do anything I ask, or act completely normal until they hear the right word from me." he said. "This one enslaved her friend over there, completely unaware. Now she is proud of it, aren't you Slave?" he asked Hanna.
"Yes Master! It was so amazing to bring Fucktoy under your control." Hanna said, practically shuddering with the knowledge that she had served her Master so well. "Thank you Master, thank you for letting me submit to you!" Hanna said with a huge smile on her face.
"Cum, Slave." he said, drawing a single finger between her pussy lips. Hanna struggled to maintain her composure, letting out a long, soft moan as an orgasm washed over her. Her body was so well trained it only took a little bit of contact and a command for her to cum. "You see, gentlemen, they have been perfectly conditioned. Not only that, they are aware of this fact and couldn't be happier. Slave, explain how you were corrupted and enslaved."
"Oh yes Master!" Hanna said excitedly, launching into an explanation of how she found the spirals, of becoming addicted to them slowly over the past weeks and months. She had known they were changing her, but by the time she realized what they were doing, she desperately wanted it to happen. She spoke whimsically about meeting Master, about cumming her brains out to the spirals, and about showing Grace it all.
"I invite you to test out these two girls. They will serve you in any way you see fit. All I have to say is 'Empty', and they will be mindless and obedient for you." Master said once Hanna was done with her tale. He slapped Hanna's ass and let go as her mind went blank again, the wonderful calm descending over her.
"Thank you Dr. Simmons. You may leave us now, we will sample these two delightful slaves you have brought to us." another one of the men said. Master turned to Hanna, giving her a smile as he walked out.
One of the men stood up, walking over to Hanna. He cupped her breasts and ass, walking around her, lifting her skirt and sliding a hand over her pussy. "What is your name?" he asked Hanna.
"Hanna Liu" she responded, still feeling nice and vacant from Master's command.
