Goddess Tangent's slave was slacking a bit and was not quite ready for service when required. He needed to be taught a lesson. It was a painful lesson as one can tell from his screams.

After slave took his punishment, he was rewarded with some funishment, which including drinking Goddess' spit and licking the sweat off Her feet and legs. He does get one more reminder at the end though, that he must always be ready to serve.
