"S-Su Yang… Are you sure that's safe?" Qiuyue asked him in a nervous voice as Su Yang's tongue licked every nook and cranny of her cave— or as far as his tongue could reach.
"Yes. As long as I don't penetrate you, it'll be fine." Su Yang said to her with her Yin Qi all over his mouth, looking like a child after eating a meal in a sloppy manner.
After reassuring Qiuyue that using his tongue was safe, Su Yang continued to lick her pink slit for many minutes.
"Aaaah~!"
Qiuyue moaned in a blissful voice as her little sister drooled with Yin Qi.
And although Su Yang cannot absorb her Yin Qi due to having an insufficient cultivation base, that did not mean he could not consume them normally. Therefore, Su Yang licked every drop of Qiuyue's Yin Qi as though they were a priceless treasure that cannot be wasted.
"Mmm!"
"Aaaahn~!"
