Good as I will explain a lesbian relationship
There are two types, 1) when the two are girls and conformation with that, this type rolls mutual masturbation, 69, and let's say the two eat and cum. 2) and what is the "man" in their case is the brunette, the "man" did not like being poked, or being sucked, it behaves the same as a man, rubber penis and 99% probability of not use, for fear that his wife would like to be penetrated by a penis and be replaced by a real man.
If you saw them on the sofa, just noticed that the brunette was over and "made man moves" to the waist and was penetrating her with his finger? It is the man who eats and she is her pleasure is to see your partner squirm and feel pleased with his finger
