College teacher loses a bet

Lucy's face burned red with embarrassment. She knew this next week would be rough. She thought she could motivate her students by promising a treat if they all passed the finals with an "A". She MEANT like buying them pizzas, or going to a movie... She didn't anticipate they would ALL request this! She kept thinking it over as her tits jiggled in front of them. "You have to clean our sorority house wearing only the clothes we give you, for a whole week!" If this was what she had to wear on day one, she could only imagine what the next 6 days would be.
