The platform was long and Lith didn't fall down in the water below as Lucy pushed him.
Lucy then placed her hands above Lith's chest and started riding him.
Lith was amazed to see this new side of his sister and he held her hips and supported her.
Lucy then bent down bringing her lips close to Lith's, she said, "you want a kiss?"
"Of course." Lith wouldn't deny it.
Lucy pulled back and continuing to ride him, she said, "Too bad. You're not getting it."
Lith chuckled. Lucy was still a rookie in all of this and he knew what she would do next to him.
As Lith had expected, Lucy brought Lith to an edge but didn't let him cum inside her. She was trying this trick of edging to show her dominance and it was seen through by the talented and shameless Lith easily.
Lith played along with Lucy for a while and in the end, Lucy was defeated and she ended up breaking her character and burying her face on Lith's shoulder.
