Rainbow Dash had promised to help Twilight with some princess duties but had conveniently ‘forgotten’ about it when the time came around. Twilight went looking for the tardy pegasus and found her napping in a tree.  
“Dash, you promised you would help me with my duties today” said Twilight but Dash only responded with a mumble and a wave of the hoof. Getting irritated at the sleeping pegasus, she came up with a plan to get the mare to come with her. She powered up her horn and pulled the pegasus out of the tree by her panties. Landing with a thud, Dash woke up with a loud groan, “What the hay, Twilight!” as she fixed her panties.  
“You promised you would help me today, Dash. This was the only way I could get you to come along” replied Twilight.
 
Dash muttered under her breath and rolled over onto her back and brushed her mane over her eyes as she tried to go back to sleep.  
“Well if you aint going to come with me on your own accord, I will have to make your come on my accord” said Twilight as she grabbed hold of the mare’s panties again with her magic and began to drag her through town via a wedgie. Dash grunted as her blue panties were wedged up her flank, pouting at the purple alicorn while crossing her hooves. The blue pegasus continued to mutter under her breath as Twilight dragged her through the town by her panties.  
“Remember to be on time, Dash, and this won’t happen again” said Twilight in a cheeky voice as she walked happily through the town dragging Dash behind her.
