I kick where it hurts

When Lexi and Ethan Lu entered the villa, Louis Lu was busy skimming through a document on the couch in the living area. There were a few documents neatly arranged on the small table in the middle of the set of sofas, a glassful of water on the other side, and a laptop. 

Surprisingly enough, he had prepared his set up in a fraction of minutes as Lexi and Ethan Lu flirted for a while before they decided to go inside. Well, Ethan Lu tried to salvage the broken atmosphere caused by his cousin which worked. 

"Don't mind me." Louis Lu muttered sensing the gaze of the two who just entered the residence. 

"Hah! Lou, stay like that and don't disturb us once again!" Pointing his finger at him, Ethan Lu warned. 

"Shh," Lexi shot Ethan Lu a shushing eye as she lightly tugged the hem of his blazer suit. Is he indirectly telling him: 'Lou, we were about to make love so don't disturb our sexy time.'
