Original Description:
 
Spike was walking down to the town, delivering a letter to Rarity. She had recently been accepted into a fashion club, and there was going to be a special runway fashion contest, and this letter was her invitation. Spike walked to Rarity’s house, and walked in, looking around. “Wow, Rarity’s house is always really really fancy. No wonder she and Sweetie Belle have been living in such luxury for a while.” He walked into the living room, looking around. “Hello? Rarity? Sweetie Belle? You here?” “Spike? Is that you? I’m in the basement doing laundry, dear! I’ll be right up! You can come down if you want!” he heard Rarity say from downstairs. He set the rolled up letter down on the table and walked downstairs to the basement. Even the basement was really pretty and luxurious, not a speck of dust anywhere. Even the carpet was really pretty. He saw Rarity by the dryer, sitting on her knees as she was taking clothes out of the dryer and folding them. She wasn’t wearing any shoes or socks, so her white feet were exposed to the warm air. Spike blushed when he saw them, and he blushed even more when he saw her scrunch her toes and he saw her purple nail polish, just like the color of her mane. Spike wanted to always do this, taste and play with his friends’ feet. Well, that had made him immediately want to do it today. “Alright…here goes.” he walked up behind Rarity, and he made sure to be sneaky. He walked up behind her, and lightly pushed her into the drier, her top half stuck inside the machine, her other half outside of it. “What the? Spike, dear what are you doing?” Spike spoke up. “I’m sorry, Rarity, but this is something I’ve wanted to do forever….don’t hate me for this.” “What do you me–ooh!”
 
Spike stuck his nose into her soles, sniffing softly at her feet. They weren’t stinky at all, since Rarity enjoyed good hygiene, even though she wears heels. “Spike, what in the world are you doing?” She tried to move her legs around, but Spike was sitting on them, so she couldn’t do much but wiggle her feet around and wiggle her toes. Spike kept sniffing her feet, taking in the clean and sweet aroma from them. “So good……so sweet.” Rarity kept trying to escape, but then, she suddenly stopped struggling, and she relaxed, sighing when she felt Spike flick his dragon tongue up and down her soles. The tongue was going all over her feet for a while, which made Rarity giggle and blush. “So the little dragon likes feet, eh? Well, my dear, I think you’re in for a surprise.” she said to herself as Spike continued with his worship. He then went up to her toes, sucking them gently. Sweetie Belle had gotten back home from school, and looked around. “Sis, are you here? Whe–” she stopped when she opened the door and saw her sister’s bottom half poking out of the drier and Spike on her ankles, worshiping her feet. She closed the door and walked away. “Nope.” she kept saying as she went upstairs. Eventually, Spike, red in the face, ran upstairs after releasing Rarity and ran out the door before she could say anything. Rarity smiled, blushing a little picking up the letter to be in the contest, and was talking on the phone. “Twilight, it’s Rarity…tell little Spikey Wikey he was a good messenger~”
