Traveling back had been a much easier ordeal with his new quirk. Binding the girl's arms and legs, he had thrown her over his shoulder and begun leaping through the sky. What he knew about the quirk beforehand, she had required a solid surface to leap from, but could still land safely without injury. His version of the quirk had no such limitations; once he began leaping, he didn't need to land. Instead, he was able to push off the air, continuously propelling himself forward. It was another crude form of being able to fly, and he welcomed its addition to his arsenal.
Arriving back at his hideout without further incident, he secured his prisoner in a cell he prepared in advance. She had squirmed feebly for most of the journey, but deep down she knew it was no use. Popstep was entirely at the mercy of this twisted bastard and could see no means of escape. The cell was made of a reinforced glass that would be able to survive most major impacts. He had constructed it in the underground basement of his lair. There was a bed, toilet, and sink occupying the space inside. She was deposited onto the bed, and Kolt stood over her with a hungry look still in his eye. "Congratulations, you are the first of many soon to become my personal playthings. That gives you the privilege of being the test subject for me to figure out how my newly found quirk works." As she looked around, she could see three more of these cells, set up side by side. This man was dangerous.
"Please let me go. I won't tell anyone what happened. I'll go home and pretend this never happened." She sobbed, tears now streaming down her face. She was desperate; she didn't want to be kept around only to satisfy his pleasure. She wanted to be home, free and give up this life of messing around with heroes and villains. Kolt simply smiled down at her. A malicious grin spread wide across his face. "As if I'd buy that story," he said. "Regardless, I just told you, you'll help me figure out this quirk of mine." A beeping then began on his wrist. The timer he had set to indicate when her quirk should wear off. "Speaking of which, I think it's time for another round." He reached out for her and she let out a scream, one that no one else would ever hear.
A couple weeks had passed now, and Popstep was still his captive. Scanning through police reports, it appeared that she hadn't even been reported as missing. She really had been the perfect target for him. She had been extremely useful in finding out most of the conditions surrounding his quirk.
-First: He was able to take her quirk any time he fucked her. This had been a concern for his as his power would be far less useful if it was a one and done situation.
-Second: If he had already had obtained her qurik raping her a second time had no benefit, well other than sheer pleasure.
-Third: Each time he took her quirk it stayed with him for longer. It seemed to work in increments of 30 minutes. The second time allowing him to hold it for an hour, the third time 90 minutes and so on.
By now he was up to holding her power for over a day which if you do the maths meant she had been abused a lot. By now popstep barely resisted, he had undone her bindings a long time back but as previously stated, she wasn't much of a fighter. He had taken some pity on her and had placed a tv on the wall outside of her cell to pass the time. She still hated every minute of it, regardless of her body starting to respond positively to the sexual assaults. He had done multiple tests to see what kind of penetration triggers the stealing of her quirk. Anal, oral and of course her pussy all seem to meet the criteria and she could be subject to any of them on a whim. It was a living hell.
There was still a couple of questions Kolt had about jos power. Could he steal more than one at the same time? If not would it replace his current stolen qurik? And if could have more than one could he combine them further? To answer these though he would need another victim. He was also in dire need of cash, building those cells had spent a lot and they were no way near perfect. Even with her quirk there was no way popstep would be able to break out but if he was housing someone stronger they could prove ineffective. He needed to get hold of some quirk dampeners and that would cost him a small fortune on the black market or he would need to steal them. As he looked over potential companies that made them he came across a familiar name. Yaoyorozu. He knew he had seen that name before and began scanning through more notes. He found it in his list of potential targets, more surprisingly in the list of U.A students. Momo Yaoyorozu, quirk creation. This was the perfect next step, her quirk would solve the majority of his issues and on top of that she was an absolute knock out. Her body all round was perfect and he had considered her as a high potential target for both reasons. His goal was set, now he just needed to figure out how he would lure her out of that school.
