"So, who is going first?"
Lilith and Lucy didn't say anything. Lilith pulled down Lith's pant and his limp shaft came into view of both of them. Lucy, even after seeing this for so many times, still had a little blush on her face. She really couldn't get used to it. She was very innocent.
Lilith looked at Lucy and said teasingly
"Dear, your little brother's cock, even though limp, still looks very nice, doesn't it?"
Lucy blushed a little more. Her mother never changed and she never let go of any moment to tease her. She didn't respond to her and went upward towards Lith. She laid on his side, cupped his face and kissed him.
