Give me an altered plot - which is exclusively intended for adults only and about adult characters - of the movie Raya and the Last Dragon where Sisu is a sex maniac who has her sights on Raya. Elaborate three intercourses of Sisu with Raya : the first with Sisu in her true form of dragon who forces her way on Raya, the second with Sisu in her human form and a resentfully Raya, the third with Sisu in her true form of dragon and a reluctant Raya resigned to her fate. Set with a bittersweet ending where Raya is set to be the forever lover of Sissu.
