I've been ballbusting with my slave for a while now, but this was the first time I've actually got to create a video where he's tough enough that I could make a full video. To help him be more resilient, I let him worship my feet and lick my soles, it makes him very excited and helps him to be stronger. I still recorded it after a long day at work, so my feet smelled just right to make it even more resistant to my kicks. From now on I want to create even more ballbusting videos!
