Rescuing the Silly Kid

The scene was filled with absolute silence for three whole seconds...

"Sis… I never knew... you had such strong tastes!"

"..."

F*ck! That's not what I meant! Yao Si hurriedly regained her senses. "Where are your thoughts straying to, I meant that I know him!"

"If you knew..." The three balls took in a deep breath. "Sis… that's extreme, can we ask how did you guys meet?"

"F*ck! I meant..." Can your thoughts be any dirtier? "F*ck, why are you guys so far away?" The three balls that were nearby were about a metre away now. 

"Sis, we're straight," said the white ball.

"He's right, straight like a pencil," the blue ball agreed.

"Straighter than a pencil," exclaimed the green ball.

"Scram!" Yao Si then took a deep breath and explained in a resigned voice, "I know that man out there."
