Yawning from a restless night of working Rarity walked down the stairs of the Carousel Boutique and fixed herself some tea. The first of many working nights for her Rarity was not looking forward to the next week. On top of her regular orders inspectors from Canterlot were coming to make sure her shop was up to code. This meant that sleep was a luxury she could not afford. A crash from the neighboring room heralded an unwitting solution to her problems. Rainbow Dash had just crashed through a window and now laid in dazed in a stack of fabrics. “Uh…hey Rarity, I was just leaving.” Said the pegasus after seeing the anger in unicorn’s eyes. “I think not!” Shouted Rarity “You…you…ruffian! You’re going to stay here and clean this up.” Dash started to get up and Rarity pushed her down. “You will not be leaving this house until I allow it.” Opening a box she kept hidden under her work table Rarity pulled out a bright red bow “And this will make sure of it.” Placing the bow on Dash, Rarity watched as the pegasus squirming slowed. Inside Dash’s brain everything was changing. She could feel her rebellious nature shifting. Slowly she found joy in servitude. That joy quickly became pleasure and Dash felt a need growing in her to serve. Her IQ was being pulled out. She could feel statistics she once knew floating away from her, now replaced only with thoughts of cleaning and loving her superior. Somewhere in her head Dash knew this was wrong, she should be fighting it, but it just felt so good to sink down and obey. Rarity stood up standing over her now grinning friend holding a new dress and a vacuum. “Now that you’ve calmed down darling I think we can come to some…terms.” Said the unicorn with a grin. Now Dash’s days are spent in servitude to the house. Every push of the vacuum making her hornier. Every sweep of the broom making her more and more submissive. Her nights are spent between the thighs of her new god. Mistress Rarity.
