In BDSM, it is done as a form of humiliation, or as a means of teasing the other. The dipping of the testes into the mouth can be used as a means of giving their submissive a taste, but not enough to satisfy, to heighten further sexual activity.

It is also a form of domination over the submissive. The quick withdrawal, heightening their 'power' over the other.
