The chair

Heather was sat in a strange chair.

She was small, as short as an 18 year old girl could be, and quite skinny, except she had 2 massive, perfectly firm and round buttocks.

This was her birthday and she had not been looking forward to it, except that she was anxious to find out her eternal sentence. Unlike everyone else in this universe, she was naughty and going to be punished.

Superiors discussed in front of her if they should make her wear a spanking diaper, which would always levitate and essentially **** her around by shoving her from her hips and crotch, and sometimes will spank, burn or shock her ass, also affect her internally in many ways, including conjured dildos made of **** fields and digestive processes.

...

The chair she sat in rocked forward, holding her ass up to be paddled. It paddles her as it sprouts wheels and drives forth through town, in forwards then in reverse, so that after she goes face first towards those the chair brings her to, it then brings her ass first to them for her to look at them get larger in field of view right besides her quivering butt as it gets spanked.

...

It went back upright and continued to drive around, showing off the brat who was sat on an electric seat, stomping in place and unable to stand away from her sitting position, crying about the spanking she received. The seat begins heating up, consistently burning her, and at random intervals shocking her with pulses of lightning.

...

Finally, it leans back, and raises her ass high in the air again, but this time, ass down with her genitals angled up, for another machine to diaper her with an advanced diaper made of sophisticated materials.
