Lyonal moaned as Obsidian stroked his dick with her hands, they moved slowly at first, but then faster. Then she looked at him and removed one hand from dick. He knew what she was doing but pretended not to notice as she would be in for a shock, literally, although the shock would be a milder one. It would cause quite a bit of pain, but not incapacitate her. It was the three strike anti tampering system. After anyone except him touched the collar for more than a second the shock would be administered and the light would change colour.<br/>After a second had passed since she started touching it, it delivered it's electric shock causing pain to run through Obsidian's body and the light changed colour to amber. Then Lyonal gloated, "You think it would be that easy to slip the collar off and to flee. It is not as simple as that. The lock is electrical and inside the collar so you couldn't open it even if you tried all night. It will release itself tomorrow mourning when I take you back. I can not release you now even if I wanted to. That shock was level one, the next time you mess with it level two will be administered which will hurt then daze you. Then for the third time onwards level three which will be extremely painful and incapacitate you for five minutes just like if you left the room or I spoke the code. So you better concentrate on pleasuring me or I will have to stop being a nice guy."
