Ye Nuan was sucking Ye Kai's cock, moving her head up and down at a faster speed, sucking him as she also felt his tongue on her pussy. They were in the sixty-nine position.
She could feel his hard cock, and as she sucked him, she wanted to do much more, taking his cock all the way to his base. She stayed there for a moment, raising her head just to take all of his cock again.
While she was doing this, she was also feeling his tongue inside her pussy. He was moving his tongue inside her pussy, sometimes, he was just moving his tongue, and sometimes he sucked her clit or gently bit that. He was also fingering her asshole. Her tight hole stretched by his finger. He moves his fingers inside and then outside, fucking her by fingers.
