A sequel to “Mouse Trap”.  
I know what it looks like and it’s not that.

Things have been going much smoother since Brainstorm volunteered to go after Topaz. Being behind her, Brainstorm could keep a better eye on her in case she tried to do any funny business. But one day, Brainstorm was in trouble. He was getting himself ready to model Silk’s summer line when he ran out of tape.
“Oh no. Why me, why now?” he said.
It was twenty minutes to show time. There was not enough time to go to the store and purchase some more tape. He wasn’t sure how long the tape would last without the extra support. He was going to have to deal with it until he could get to the store. Meanwhile, Topaz was hiding backstage.
“Ms. Shine.” Asked Topaz
“What is it Topaz?” Said Silk, sounding a bit irritated.
“May I wear the dress with the long skirt that touches the floor?” Asked Topaz.
“Okay, but why.” Asked Silk, looking rather suspicious.
“I am the only pony who can make it look good.” Said Topaz, sounding very confident.
Silk was going to reconsider, but there was trouble with one of the models and she had to hurry. She had no time to waist.
“Okay, fine” she said, and hurried away.
Topaz then left to go get dressed. Once she was dressed, she pulled out a back containing a bottle of cooking grease. The show was just beginning. All the models wear ready to go onto the stage. It didn’t take Brainstorm long to notice that Topaz’s horn was glowing?
He wanted to figure out what she was up to.
“Topaz, why is your horn glowing?” Asked Brainstorm.
Topaz answered, “What, this? Are you jealous that you don’t have a beautiful glowing horn like mine?” Sounding very over confident.
It was time for her to go on.
“Break a leg.” Said Brainstorm.
“I’ll break yours.” Said Topaz, to herself holding the bottle in a cyan aura under her dress.
Topaz marched onto the runway, flaunting her figure, showing off the dress, and pleasing the crowd. When it was her time to get off, that was the signal to begin her plan. As she left, opened the cap of the bottle that she kept hidden under her dress. She poured the liquid onto the runway and walked off. Meanwhile, Brainstorm was having his own set of troubles.
He was focused on the tape coming loose. The tape became more and more loose with each step. Suddenly, he felt his tape came off, freeing his part. He clamped both his hind-legs together and started to slow down his walk. Then he came to the grease. He felt his hooves slip on the slippery substance.
It was not going to be easy. He made his poses, but his legs kept slipping on the grease. Then he noticed that his part was about to be exposed. He got up on his hind-legs and try to cove himself, but he was too fast. He slipped on the grease and fell backwards.
There he was sitting on his butt, legs apart, and his panties exposed. He looked out at the audience, and then he looked down and saw his panties. He quickly pulled down the skirt, got up off the floor, and headed for backstage. Backstage, Silk scolded Brainstorm.
“What were you thinking!?” Scolded Silk.
“Making THOSE poses and almost exposing yourself!?” She continued, sounding angry.
“But Silk, it wasn’t my fault. The end of the runway was covered in cooking grease.” Explained Brainstorm.
“Really? How could cooking grease get on the runway?” Asked Silk, in disbelief.
“I’m not 100% sure, but I think it was Topaz. Anyway, go ask any of the other models. I’m sure they must have felt the grease on the runway.” Said Brainstorm.
“Okay, but what makes you think it was Topaz?” Asked Silk.
“Before the show, I saw her horn glowing.” Explained Brainstorm.
“Well then, I will go investigate, but I don’t want any more funny business.” Said Silk sternly, and left.
Brainstorm left to. He had to get more tape.
