During a training session, Rainbow Dash and Spitfire decided to have fun with Fleetfoot by issuing her a challenge.  
“Hey Flootfoot, I bet you can’t do 50 pull-ups” said Rainbow Dash.  
“I can do 50 in my sleep!” responded Fleetfoot with confidence.  
“Well I bet you can’t do 50 pull-ups while in a hanging wedgie!” added Spitfire.  
“I bet you 50 bits you can’t do 50 wedgie pull-ups” challenged Dash.  
Fleetfoot blushed as she thought about it for a few moments before responding.  
“Ok, bet accepted….”
 
–– SEVERAL MINUTES LATER ––
 
“25…26…27……28…….29…….30..” counted Spitfire, “20 more to go, girl!”  
“Come on, Fleetfoot! You can do better than that!” yelled Dash as she cheered on Fleetfoot.  
Fleetfoot continued with her pull-ups. For her, pull ups weren’t that hard for an athlete of her caliber but her panties wedging up her flank each cycle made them quite painful for her but she kept her mind focused as she tried to do more so she could win the bet.
