"I heard that your cock is in need of a good slapping session! So, I made this video to tell you exactly how I want you to do it, don't worry, there will also be some stroking... I just wanna make sure that you remain as hard as possible while you hit your dick!  Follow along this CBT JOI video and slap your cock as hard as I do!  If you do a good job, I will allow you to cum after my cum countdown!" TL:DR - femdom JOI with dick slapping instructions and cum countdown.
