I’ve been listening (and masturbating to) to these audios by Julie Kohler-Bush. They are simple repetitions of phrases but oh-so arousing. I put on a slideshow of my favorite masturbation muses, and had to confess that yes, I’m ashamed, and I tried (but failed) not to cum. 

• Aren’t You Ashamed of Yourself
• Aren’t You Ashamed of Yourself – you should be
• Don’t You Cum – You Don’t Get to Cum

Note she is on Reddit at Julie Kohler-Bush. She posts mainly on GoneWild Audio. And she personally assures me that all her orgasms on the audios are real.
