I like watching extreme ball busting....where the mistress pushes the slave to point of damage ( of his testicles)...but you always see the guy laying on ground (in pain) (Can be simulate) after the session (fade to black screen) or the guy screams in pain and ( fades to black screen)...It will really kool..If they had and exit scene where they interview the slave and show the damage cause by the session or show the slave been rushed to the exit ( to the hospital)...kinda thing

Just my request!!!
