Any hypnofetishist will understand this; you're done gooning for the night, you're tired and it's time to switch off. As you go to close your browser you miss and accidentally press play on some audio or a video. Your headphones are still on your head as it starts to play. you start to fumble around to stop it. "I have to go to bed", you think. The audio starts, you get confused for a second even a little aroused. You fumble around trying to stop the track, you can't seem to focus on what you are doing.
You start to wonder why you wanted to turn the track off. You start to feel sleepy but this is different, your cock goes hard and your hand is drawn to it. "fuck what was I doing"?.
You can hear the words of the track but they are in the background now. So soft, so relaxing. You find yourself settling back in your seat, arms dropping, it feels so nice. Your hand is now round your cock again and you are breathing heavily. For a moment you can focus on the screen and see the track is 90 minutes long. Your face is expressionless and your lids are fluttering as your eyes roll back in your head, even though you are panicking inside. You don't even know what track you turned on....
That is your last independent thought before you follow the words completely and blissfully. She has you, I wonder what will happen to you.
