The Sister the Fake Princess Recognized Was Actually the Real Prince

#Help! I slept with Prince True as my sister Jiang Wuyou flirted with a beautiful sister, who was beautiful and aloof, as beautiful as a fairy. She pestered people with "sister" and "sister" every day, and finally deceived them. On the night of the traditional Chinese medicine, Jiang Wuyou was nestled in her sister's arms when she suddenly felt something hard hit her body. She looked down - Sister, is the dagger hidden in your crotch a little too big? ? ? What's even more shocking is that she is a fake princess! And the "sister" whom she slept with again and again, defrauding money and sex, is the real heir to the throne! Help, what has she done? Is it too late to run now? [The female protagonist grows up and will become a queen later (the author asked). The male protagonist is not named Liu Ruyan, family members, please rest assured]
