Jim sat at his desk and his mind was racing. Changing his sister like that was evil, a part of him knew that, but then she didn't even have the slightest clue that he did change her. Or did she? He couldn't read her mind, but everything she did and how she acted was exactly like she meant it. But then the power of the Yo-Yo could just be so strong, that she couldn't do anything but do it like that. Before he continued he just had to figure out how it felt like to be under someone's control with that Yo-Yo. He decided to give himself some harmless triggers, but when he was about to plan them he realized: as long as he did them he really wasn't being controlled. And as long as he knew he was in control he wouldn't feel like the victim. There was only one way he could truly experience what it was like to be under the control of someone else. Finally he decided to try it, so he recorded a few commands, took the necessary steps to ensure this wouldn't go out of hand, and then he let it happen.
"Everything ok?" Jim heard the voice of his sister waking him up. She must have come into his room while he had himself knocked out and reprogrammed.
"Yeah, I am fine." He mumbled and got himself into a proper state again. He wasn't sure if he should test his commands while she was around or if he should send her away first.
"I found this on your desk... what the hell is it?" Edith continued and when Jim looked towards her he realized in horror that she was holding the Yo-Yo towards him. She must have grabbed it while he was under, which meant she could now... Suddenly his mind felt so blank and fuzzy.
"How are you feeling?" Jim heard the voice of his sister waking him up. For a moment he felt all dizzy, but then he remembered the last thing that happened before he drifted away. In panic she shrieked off his desk and stared at Edith, but she just had this sly grin on her face.
"What... did you do to me?!" Jim asked in panic, and he just prayed she did not uncover how powerful that thing really was. The grin on Edith's face became wider.
"I might have learned one of your secrets." she purred "But don't worry, it won't be too bad."
"What did you do?!" Jim asked again and desperately looked around for the Yo-Yo "I need my Yo-Yo back, it is really important!" He rushed up from his chair, but Edith just stared at him calmly.
"Sit!" Instantly Jim felt his ass drop to the seat again. He looked around confused for a second because he couldn't get himself to stand up again till he realized that she must have gotten control over him.
"Edith, please, I can explain everything!" he tried to get the situation back under control, while he tried to not look too horrified by the fact that his body now obeyed the voice of someone else.
"That's not necessary, I already know everything I have to." Edith responded with a dark undertone that made Jim shiver "Why don't you just undress and throw your clothes on a pile over there?" She continued and suddenly snapped her fingers. Jim was confused for a moment why she did that until he noticed himself getting up and starting to undress himself. She must have made him obey a sentence if she snapped her fingers afterwards!
"This is all a misunderstanding!" Jim was really in panic when he realized that he had no way to stop his body from pulling his shirt over his head, throwing it to the designated spot and then continue on his pants.
"I think I understand just fine." Edith said with a sexy smile when Jim pulled down his boxer shorts and threw them after his pants, then sat down on his chair completely naked. "I also borrowed some of your earlier commands, I am sure you don't mind, do you? Get hard!" And with the snap of her fingers Jim instantly felt the blood rushing towards his cock as he realized which command she had 'borrowed' A moment later his dick was throbbing at an artificial level of hardness and he knew that it wouldn't go down until she used the other trigger on him.
"I like what I see..." Edith purred and reached out for Jim's steel-hard boner and pumped it a few times. Jim figured that her commands to lust after him was causing this. "Mmmh... now masturbate until I tell you to stop. And don't cum! You only cum when I tell you to!" After the snap of her fingers Jim felt his hand reaching for his dick and he started pumping it. He was unable to stop his hand, like someone else was remotely controlling it. And the worst ting was: it actually felt good. Edith watched him working his shaft for a while, then she went down on her knees, pulled her hair back and kissed the tip of his dick. Briefly the idea of taking back control by force at this point came to his mind, but he didn't have control of his hands to actually do it. All he could do at the moment was to sit there and masturbate, while Edith very sensually enjoyed licking and sucking the tip of his cock. Unsure what to do, he just stared at the back of her head, felt her tongue on his dick and continued to pump his dick like there was a price to win. He got rapidly closer and closer to an orgasm, as beside the fact that he wasn't controlling this, it was actually quiet pleasurable. By chance Edith did exactly what he had kept himself from making her do to him, except that she was in control.
"Edith... I am.. cuming..." he eventually moaned.
"No, don't worry, you won't." she returned with extreme certainty. And when Jim was about to burst his load he realized: she was right. Something prevented him from getting over the edge, despite the fact that his dick was already twitching and ready to blow it. "Stay on the edge till I allow you to cum." Edith said followed by a snap of her fingers, then she moved back a step to watch her brother. Unable to stop Jim was forced to continue to masturbate his dick, and as ordered he stayed on the very edge of an orgasm, but just couldn't cum. And Edith just watched him with a mischievous grin. After a minute or so he already had the blue-balls of his life, and he desperately had to blow his load right now, but the power of the Yo-Yo was stronger than his urges.
"Edith... please!" he moaned.
"Now you know how it felt when you kept me cuming..." she laughed at him and got Jim confused how she even knew that since had erased her memories.
"P-please..." he begged her after another minute of staying at the verge of cuming. His balls already hurt, his dick hurt from how frantically he was masturbating, but Edith didn't seem to care. She just stood there and watched him suffer. A few more minutes of pleasure and agony continued till Jim's mind was completely consumed by the need to cum. A this point he would have probably done everything to get off, he would have even handed over the Yo-Yo to her just so that she could hypnotize him to blow his load, or whatever else was necessary. Then somewhere from far away of his sexual hell he heard the voice of his sister talking to him again.
"From now on whenever I order you to cum, your dick will first get hard as steel if it isn't already, and then you'll have a mind-blowing orgasm." All that Jim heard was the chance for relief "And the next time I use that on you, you will make sure that you will cum all over your body." A snap of her fingers sealed his fate. "Cum now!"
Never in life had Jim felt a need to cum so urgently, and never in life an orgasm had overwhelmed him as much as this one. His body went totally out of control when his dick was finally allowed to launch what had been almost boiling in his balls. A loud and obscene moan started the whole thing, and then his body started to spasm uncontrollably, when his dick pumped shot after shot out of his balls. He felt the warm fluids splatter on his chest and belly, but there was no way he could stop himself from doing it. In fact there was nothing he could do right now but to have the greatest orgasm of his life. "Cum now!" he heard the voice of his sister and his orgasm restarted with what felt like twice the intensity. If there was any control left over his body he lost it. He screamed and came, he twitched and slid to the floor where he continued to twitch. It felt like an eternity till his second orgasm finally subsided, and his mind slowly returned to the world.
"You can stop masturbating now." he heard his sister say and he felt the control return to his hands. It took him a moment to realize that he was laying on the floor on his side, his juice dripping from his chest and belly forming a puddle on his carpet. His dick stayed hard as steel, because she hadn't undone that, yet, but his entire groin hurt, and he couldn't do anything but to lay there, desperately trying to regain his breath. He knew he had to get back in control, but he had no idea how.
