As soon as Sara heard her mother leave the house, she jumped back out of bed, took off her clothes, and went down the hall and into Richard's room.
"Wow Richard! I watched the whole thing! You made mom swallow your cum!"
"Not really Sis. She was startled at first when I held her head, but she didn't try to get away. I think she really liked it! She was really using her tongue, lapping on my ball sack. Want me to eat your pussy now?"
"That would be great but I'm going to go see if I can do the same thing mom did to you to daddy!"
"Okay, sis! Good luck, and see you in the morning!"
Sara went back into the hall and down to her parent's door. As usual, the door was slightly open. She pushed it open farther and entered. It was dark, but she could make out her dad's sleeping form on the right side of the bed.
She got close to the bed and found the covers were barely covering her dad. She pushed them away gently to reveal his cock. It was not hard, but looked inviting.
She bent down and kissed the tip, then lifted her daddy's cock and slowly swallowed it to his balls!
Suddenly the bedside light came on and Sara looked up to see her dad looking at her, smiling.
