In Japan I found a video which focused on girls in wheelchairs. The scenarios were mostly school girls in wheelchairs who were late to class, and a perverted businessman who pushed them around. They'd mostly just plead for him to go faster, and he'd look at their helpless legs (this was the money shot).
Other scenarios had the school girls bumping into one another in their wheelchairs and oddly enough, even being bullied for being in a wheelchair.
The cover claimed the girls were REALLY wheelchair bound, but this wasn't so; most, unfortunately could walk and were also featured in some farting videos Sparky purchased.
This girl is being pushed around.
When the other girl spots them she begins laughing at her.
