This is a clear demonstration of roles within a cuckold marriage.

The hotwife:  the center of attention and activity.

The bull: having been invited into the marriage for this purpose, is welcomed inside her.

The cuckold: participates in his wife’s pleasure in a manner that reassures and empowers her without interfering in her coupling.

Her cuckold may get dismissed from the room after this moment, but if so, he'll leave quite happy.
