If you mean Fawn, doing it to you.
Then speak to Arlene, in the Torture Rack, then speak to Fawn, in the Torture Rack.
Funny thing is, i tried to endure everything that Fawn did in that quest (end 25+) and my character hallucinated.
My character saw Mystira (tentacle lady).
All I saw was a Pure White Ancestral, Lady.
