After carelessly becoming the guarantor for her friend's loan, she is told to settle his debt of tens of thousands of dollars... "I'll wait for payment. That is, if you let me have sex with you." And just like that, she's pulled into it. "But, I'm a virgin... Am I gonna be okay?" Just as she thinks she's going to be made to suffer, she gets treated kindly and gently, making her first sensual experience all the more confusing...
