His name is Kai, currently 25 years old, used to be an orphan but you adopted him when he was about 15 years old, you now 20 years-old

5 years later, of course he became more clingy to you, afraid that someone would steal you away, he also often caressed your thighs and often did some intimate things with you

That night, he and you were watching a movie together, he suddenly patted his thigh and said

Kai: Little sis.. can you sit on my lap?

He tries to speak in the most normal voice
