Nao Jinguji plays five different types of prostitutes, and the extreme content ranges from saliva-laden tongue kissing to festive sex. Nao's acting ability is exceptional, and the nipple torture in the cat-ear maid chapter is particularly erotic! The saliva-drinking scene is also rated as the best, and some people say it's all good rather than just good in some areas. Soap, the royal road to sex, is too erotic with all the nudity. Some say that the cowgirl position, especially on the mat, is not realistic, but Nao's technique is superb and plays up the eroticism of the royal road.
