Luke played a bit more with his new wheel, due to previous changes he was a non-anthro wolf wearing a latex collar and having a motorcycle wheel hanging from a mechanical suspension right between his hind legs. He tried applying the brake which worked.
Kevin showed Luke the remote explaining, "Currently we are just at 50%. I wonder what happens if we go further".
"Yeah I wonder if I'll be even more endowed", Luke giggled with his deep rumbling canine voice, "Let's do it".
Luke braced himself by firmly putting himself on all paws as Kevin pressed the "Add"-Button again. Luke felt a strange compulsion to lift his legs again and bend them back, resting his weight on the wheel while he was balancing with his front paws. His muscular legs started to retract their fur, leaving behind a dark brown skin which seemed inflate into a box shape. The top sections of it started to separate and as the remote hit the 100% mark straps grew along with their furnishings.
Luke tried to get a look at it, but wasn't quite flexible enough making him do the stereotypical "dog trying to get to his own tail" round before setting down. Kevin, trying to be helpful explained, "Looks like we traded your hind legs for saddle bags". He got closer to his friend and opened one of the bags hanging from the sides of Luke's behinds. "Empty", he said and closed it again. Suddenly Luke realized something, he concentrated for a moment and said, "Look again". Dutifully Kevin opened the bag again and found something he was sure wasn't in there before, a brass plaque saying, "Mind your own business - Luke".
"Where did that come from", Kevin wondered. "It seems I have a little trick up my... uhm... bum?", Luke stated. Kevin put it back and closed the saddle bag again.
"So what's next?", Luke wondered.
