There seem to be two competing meanings for the term 'free use':

1. Some kind of sexual interaction with someone while they are doing mundane things like laundry, gaming, etc. - where the appeal seems to be the disregard for the sub, attention-wise.

2. Blanket permission to engage in arbitrary sexual interaction at any time (possibly within a particular time window) without establishing consent first, though potentially still with the option to reject it - where the appeal seems to be the unexpectedness and the disregard for consent.

Is there some way to distinguish these two, terminology-wise? As they seem to push pretty different buttons for different reasons.
