The 'scene' I liked the best..

I picked another lady, and lifted her aboard. After fastening her hands to the yoke overhead, I impaled her on the dildo through the crotch hole in her slacks and allowed her feet to rest on the footrest. It spread her quite a bit. The chains from the pipe were fastened to two strong clips, fastened to the back of her areolae through small holes in her shirt. Pushing down with her feet allowed her a little more freedom for her hands, but pulled badly on her breasts. Her wrist keys were laying on the top of the yoke, but she would need to get a few inches more play in her wrist chains by pushing down on the footrest. The wrists would then be loose enough to, just barely, reach the ice cubes containing the keys. A butterfly vibe would keep her interested.
The walk through the wilderness was nice, it had been a while since BabySub had been out and about like that. She appreciated the semi-freedom, and the scenery as well as the brisk walk. Always curious, her mind was trying to figure out where they were going, and why.

It became obvious when they reached the first clearing, and she pondered the situation her friends were in. Interesting, what was next? Her eyes widened as they reached their next destination, and she saw the 'aparatus' waiting to be used. Her heart hammered, and her cunt twitched as she was grabbed and placed on the dildo, mewing quietly as it slid inside. Legs wide spread, BabySub gasped as the clips were attached, and pinched at her nipples; her breathing hard and laboured. The vibe was put in place, and she saw the keys ontop of the yoke. Blinking, she watched the others as they left, moving onto the next clearing.

Twisting occasionally, BabySub clenched her cunt around the dildo, letting out small cries of anticipation and by then need. She jumped as she heard the voice over the walkie talkie, and listened. The ice by then was starting to melt a little, and BabySub reached out with her tongue and caught a drip. How long would it take to melt completely..? "OOooohhhhh......" as the butterfly started, humming away at her clit. She pressed down slightly on her feet, "Oooouch..!" as her nipples were pulled painfully by the chains, but she realised she got closer to the keys... hmmmm....
