My Sister Disguised Herself as a Man and Lied to Me for Twenty Years

Ye Cheng, the adopted son of the Wu family, received the sign-in system at the age of seven and has been signing in silently for twenty years! Just when Ye Cheng complained about the ** of the sign-in system, the system was greatly upgraded. Not only could selections be triggered at all times, but the rewards were even more luxurious! Best of all, it can also trigger bonus enhancements to get double rewards! Ye Cheng's first choice triggered an unexpected reward: a shocking secret about the Wu family! After reading this secret, Ye Cheng was completely dumbfounded! Ye Cheng couldn't believe that his brother Wujuro, who had been with him day and night for twenty years, was actually a woman? ! If my younger brother Takejuro is a girl, then... Ye Cheng's face turned completely green when he thought of the two of them practicing together since childhood, sleeping together, and not long ago when they visited a brothel together, drank wine, and picked up women!
