Mr.Tomcat,this may well be a classic case of transference.This sub is resentful and angry at the no intercourse penalty imposed by her dominant,but knows good and well that she had best not show this resentment based set of emotions to him in reaction to this penalty.Well the sub's resentment grows to the point that it has to come out somehow and this situation at this house is the perfect setting for her to do this emotional release,what with her dominant being absent from this host's home.

On the conscious level the sub knows full well this bratty behavior of hers will be reported to her dominant,The host and other guests are to her merely the
means to transmit this resentment and anger of hers.

One larger example of this transference setting I have seen is that of a chain of
restaurants,the management of which had a culture that encouraged these managers to treat the wait staff and cooks like crap.When an unfairly treated employee objected to anything they were suspended without pay for a few days or fired on the spot.These poorly treated employees having no other means of release,transferred their resentment to the customers by means of displaying a really bad attitude and poor service towards the customers.
Just as a side note on the restaurant story,4 out of 5 of this chain's locations closed at the same time due to lack of business.
