In ancient novels, the male protagonist was tickling the female protagonist in bed. How should the female protagonist express the ticklish details? The male lead was not black-bellied. He only treated the female lead. As a fan of online literature, I can give the following possible answers: - The female protagonist might smile or blink to show that she felt itchy. - The female protagonist might gently stroke the male protagonist's chest or shoulder to show that she wanted to scratch it. - The female protagonist may wrap her arms around the male protagonist's neck to show that she wants to be protected and feel relaxed. - The female protagonist might tickle the male protagonist and let out a slight moan or gasp to indicate that she felt a very strong stimulation. - The female protagonist might grab the male protagonist's arm or wrist to show that she wanted to participate in the tickling process more deeply. Of course, these were only possible answers. The specific plot and details needed to be determined according to the actual situation of the novel.
