I giggled as Inga jumped and whimpered. I'd taken a look at the remote and figured out that the dial controlled intensity, and the button could be pushed or rocked. I was pushing it in, but now, as I pulled the shock fork away, I dialled the dial back on the remote to minimum then began moving my thumb from side to side.<br/><br/>I figured my guess was correct as to the function, mostly from my sweetpea's reaction. While flipping between what I assumed were paired vibes, one in each hole, I walked softly into the narrow space between the cross and the wall, then jabbed the cold hard spikes hard into the underside of her right breast, lifting it up on them. They weren't sharp, wouldn't break the skin, but bet that hurt. I hoped it did.<br/><br/>All the while watching for the rapid shake of the head that would tell me it was too much. After a few seconds to let her get accustomed to this discomfort, I thumbed the button on the shocker again. held it there for a second or two then released the button and pulled the prongs away.<br/><br/>Now I set the remote to what I assumed was both vibrators together, still at the lowest setting, set it aside, and I touched the prongs gently to her other breast, to see if she would react, then pulled them away without shocking her. Then touched them either side of her belly button. I ran them down from there until they were both in the crease between her mound and her thigh, and pressed the button again.<br/><br/>After a few more minutes of giving random shocks and no-shock touches to different bits of my dear Inga's naked flesh, ai decided to change the game. I had noticed she was wearing a dildo gag, which extended out from her face as well as going into her mouth. Time for a ride. I unhooked her from the cross, keeping her hands behind her back until she was on the bed where I secured her on her back, spread-eagled.<br/><br/>I didn't hear the noises from outside the bedroom. The door was closed and I was baking clinking noised with chains and buckles. I quickly stripped off my tracksuit - fitness worker's business suit! - and knelt over her head, facing her feet with my knees on her armpits, "Right, my darling, you may cum as soon as I have. I turned the dial on her vibrators up to max and lowered myself onto the dildo in her mouth, grabbed a nipple clamp in one hand and reached forward with the other to caress and pinch her clit through the rubber strap that was pulled tight across it.<br/><br/>I was getting close and so was my pet, when the bedroom door opened...
