That's the sound of the police, woop woop

As they continued fucking, Joseph was getting tuckered out but kept going, that is when the police broke down the door and said it was illegal for women to randomly fuck a man without supervision. Led by Leona the sergeant and Lawbee the 2-star general, the two of them apprehended the women, treating Joseph like a **** victim despite his protests, taking him straight to a facility for male sperm extraction. They thought they could treat him like a guinea pig while they tested him and tried to find out where he was from and why they didn't know of his existence. He was given the same privileges as other men, allowed to pick women from across the world to fuck, and request anything he wanted, but leaving of his own free will was prohibited. On the bright side, he could request his women, delighted by how they all showed such care for him, especially those from Muscle Dom who seemed to skip all the courtship due to the alien and unique situation of male love being reciprocated and given. He worried about his wives, new and old, but knew that since he was in this situation, he might as well take advantage of it. From then on, Joseph combed through the lists of women to find the absolute best, letting the world know of his sexual prowess and unique strength, only allowing semen extraction via women he liked. Just like that, he got the rest of the roster:

• Leona: The police sergeant who comically wore a tight police uniform due to current custom clothing costs having very expensive prices, having a very long and distinguished career. | +1 strength
• Lawbee: The 2-star general outshined everyone in what she did despite trading some of her strength training for flexibility and more time refining her skills in the blade. Most of what she has is simply what is naturally given to most girls, still putting in that bit of effort to keep herself fit and agile. | +1 flexibility
• Kalara: A woman who has lived a complex career as a veteran, firefighter, martial arts champion, ninja, and microbiology professor. She spends her downtime at biker gangs and commuting from her ancient ninja village that focused on their skills as their form of strength, leading to stronger bodies but ultimately still mostly human forms. But this doesn't stop the men of this world from fearing them, picking up on not simply the physical clues but the aura of the strong and the murderous intent they have honed throughout their lives. | +1 skill
• Aneli: A woman who is believed by her reclusive village to have battled their local land god and eaten its essence, growing a completely real and alive monkey tail. She is great friends with Kalara and is descended from a sister village of samurai, surpassing Kalara in strength from her lifestyle of training and combat, a life she enjoys, just like how Kalara loves hers. | +1 focus
• Striker: Someone who was mocked at and laughed at for having a weak and overgrown body in the erotic areas, such as her tits and ass. But what people didn't know was that her body was very desirable and in exchange for strength, she seemed to have boundless endurance. | +3 endurance
• Eda: A generation before Kalara and has won all karate and heavyweight tournaments she has been a part of | +1 strength
• Elena: A girl from an adventurous mountain tribe who surpasses monkeys with her tree-climbing and distance-covering. | +1 charisma
• Yuki: Working in a secretive exorcist organisation, Yuki has an eccentric personality and a keen 6th sense, having a stellar beauty that even turns the heads of women. | +1 charisma
• Rose: A stock broker and multi-millionaire | +1 smarts
• Grace: A world-famous engineer on the level of Nikola Tesla whose female counterpart is her ancestor | +1 smarts
• Milly: Recently finally got her growth spurt and put her bullies in their place after they had messed with her for so many years because of her glasses. | +1 confidence

All these women were requested, sexually satisfied, and wooed into Joseph's harem, all of whom are willing to die for Joseph due to his caring and lustful qualities. At the same time though, they are all very thankful that Joseph is treating them so well, requesting the most expensive and highest of quality dishes, equipment, subscriptions, clothes, etc. He and his girls were having fun bankrupting this fucked up organisation, messing with them when they could while treating his women to whatever they desired. Then, the moment they stopped catering to his every whim, Joseph broke free with his ladies, causing severe damage and getting the other men to a safe distance so they might finally live free lives if they so chose.
