My understanding is that iStripper XXX cards feature multiple clips in which there are extensive periods of XXX action whereas iStripper cards rarely have any but occassionaly the girls briefly go a little to far for "Full Nudity" so the card has to be rated XXX.
In practice, within the rest of the Adult industry these days the notion of XXX applies more to any use of penetrative toys. Places like MFC go even further explicitly defining XXX acceptability as 'recognised sex-toys' (not fruit etc.) It is a shame Totem XXX definitions were 'set in stone' so many years ago.
Protracted clips of mere hand/s work for G-spot stimulation, is considered fairly 'middle of the road' now, which is something Totem Formula doesn't seem to appreciate in its delineations of what is 'non xxx' or 'regular iStripper' per se. Time to review the definitions they use, as well as how they apply them perhaps.
IMHO, presenting a list of acts a model must complete in order to earn a loading is not
a good way to go especially when you mix these acts up within single clips.
