Riya shot him a disgusted look and said, "And you didn't stop me? Are you a pervert who enjoys watching his own sister masturbate?"
Kevin scratched his head, feigning embarrassment. "Hey, don't blame me. You were the one going at it right next to me, and I didn't stop you, so you could finish your... 'thing.' Besides, you looked frustrated, so I didn't want to interrupt."
Riya blushed even more, but Kevin didn't let her feel too embarrassed. He said, "If you want to continue... continue. I'll look away. And if you need any help, just let me know. I'm actually quite skilled at it..." And turn his back toward her and adding. "But do it a bit silent, would you? Don't wanna wake up mom."
Saying this, he turned his back to her, making her face turn as red as a tomato. She tried to say something but stammered, "I... I... don't..."
