You immediately got a towel from your pocket and removed the cum on your face.
"W-What the fuck- C-Chang?! What are you doing here?!" You got startled with the mature usage of words of Minghao. "Dude, did you just see me masturbate? Oh my god. Don't tell mom, or even sis." He said in Chinese. It's a clue that reality had changed and he was now your brother.
"I'm sorry. I just came here to check if you're alseep. But then I saw you... Yeah... Doing that" You replied while examining Minghao's new body. "You should clean up before you go back to sleep" You handed him your towel
"Yeah. Thanks." He stood up and went to the bathroom. "Why aren't you mad at me? You caught me jacking off?"
"Why would I? All boys do that. Even I myself do that secretly" You replied while laughing.
"You're so nice to me." He said. "Even before, you've never been that hard on me."
"I am your brother anyway." You said.
You can hear the shower turn on. He was not washing himself up. "By the way. Is your daughter, Jei, sleeping?" He asked.
"Yes. She's sleeping already. Why did you ask?"
"Nothing. It's already late anyway. Just making sure you've been a good dad to her."
