Question: how to perform femal extended multi orgasmic state? 

Answer: The guy must hold on with his mental and physical powers while working on the c spot - continuing with in-and-out exercise when she's all worked up. Continue even after she gives shrieks and shudders or maybe beating her hands using the filthiest language, twitching her body and facial muscels, eyes kept closed. But remember, to achieve that state she's to be in with him... though 'him' would be the main player to bring her that state. She can't achieve it if 'him' is an average lad.
