Now Greg was not sure but he looked at the vials and saw one that is would make him smaller.
Before Mark could do anything Greg downed it and he started to get smaller, shorter. Ending up at about 5'2"
This was not a good thing for Greg but Mark was enjoying it.
You see Greg got shorter but didn't lose any of the weight. He became rounder and rounder. Fortunately he had some muscle on that tiny form but he was so fat now that he waddled.
He threw his shoulders back and sprinted toward Mark. Well sprint in a bit of a mistake. His belly lead the way and bumped into Mark a full two minutes before the rest of him got near.
If Mark had measured Greg's waist at this point it would have shown that he was almost twice as big round as he was tall now.
FIX IT Greg shouted.
Mark shoved a vial at Greg and he downed it quickly without reading the label.
Greg's mind became cloudy and soon he was unaware of any changes that had happened to him and now easily controlled by Mark.
