Nice ladyfriend you have

Suggestion.

Maybe once you could have more time to do it a bit more sophisticate, that mean a little acting.
You can wear masks during session. The cam can be set in 3 different positions.
One when she goes in, one for dialog and final one for ball busting.
Also you can admit 1-2 kicks that will bring you down.
Regarding ball bondage this could be from no bondage, the bondage you used (balls together) and the more vulnerable one with balls tied separately.
Dialog are OK in your language but you can add subtitles. This is a simple text file with hour, min, sec, milisec and English text.
You can do it manually or using a software like subtitle workshop that you can download from internet.
I think will be more fun for both and maybe you can use later clipforsale in order to have some income.
There are a lot of commercial Russian ballbusting clips that are excellent in my opinion, maybe is time for Romanian clips to move into competition .
