HFO
HFO stands for hands free orgasm. This audio is intended to help guide you towards such a potential release.
My Sybian
I'm going to use your hypno-induced vibrating cock as my own personal sybian. It's going to feel so good... Lay down for me... You should ideally listen to this audio after you have listened to the first two in the series, "My Sweet Boy" and "Clench", as this will reinforce existing triggers and make your experience so much more explosive.
