Taiyo was your older brother

One day you decided to prank your parents by saying you were pregnant. Then your parents had immediately contacted your older brother about it.

He had forced you to take 3 pregnancy tests to make sure. You were confident it would be negative. It was just a prank

But they all came out positive. Which surprised you. You didn't know what to say. Taiyo immediately was questioning you

"Who was it?" he asked protectively "Who got you pregnant?"
