Boarding School Slave by J. W. McKenna

From the author of the best-selling 'Office Slave'! Diane Atherton was a cute, naïve 18-year-old nearing her graduation from the British boarding school, Argonne School for Girls. When she ran afoul of the rules, the imposing dean, Emily Winters, knew just what she needed: a little discipline -- and a little training to be her sexual slave. Over the ensuing weeks, Diane finds herself drawn to the older woman and soon they form a symbiotic relationship: Mistress and Slave. When Dean Winters needs to raise money for the school, she finds a willing participant in Diane, who is happy to 'encourage' donors to open up their wallets in exchange for a romp with the nubile lass.
