Candy and Bill finished up in the bathroom and when they went back to the girls' bedroom (dressed only in towels) they saw that Staci was still sleeping in her bed.
Bill laid down on Candy's bed, leaning his head against the pillows. Candy approached Staci who was still face down under the covers. She kneeled down next to Staci's head and gently dipped her tongue in Staci's ear. Staci let out a little moan in her sleep. Candy started kissing down Staci's neck as Staci woke up and realized what was happening.
"Hi Sis," Staci said sleepily, "aren't you ever satisfied?"
"Hasn't happened yet," Candy said with a sly smile on her face.
Staci turned over so she was laying on her back. She noticed that Candy was wrapped in a towel and that her hair was wet.
"Did you and Daddy take a shower without me?" Staci asked pouting.
"Yes and guess what? Daddy fucked me in the ass!"
Staci quickly sat up in bed and turned towards her father.
"Is that true Daddy?"
"Yes, it's true. Your sister's ass was so firm and tight..." Bill trailed off, remembering what has just happened a few minutes ago. His dick was already starting to stiffen under his towel again.
"Does that mean you like her better Daddy?" Staci asked.
"Of course not baby girl! Don't worry, I'll give you the ass-fucking of a lifetime as soon as I have the energy."
Staci continued to pout, not fully satisfied with her daddy's answer. Candy sat down on the bed next to her and stroked her face.
"Don't act like a spoiled brat Staci. There's enough of Daddy for both of us."
Candy leaned over and kissed Staci on the lips. At first Staci didn't respond but then she got into it, sliding her tongue into her sister's mouth and caressing Candy's back with her hands. Candy was running her fingers through Staci's dark hair, gently pulling at times, which she knew Staci liked.
Their father was propped up on his side taking in everything that was going on. Staci undid the towel that Candy was still wearing so they were both naked.
"Your breasts are so beautiful," Staci whispered and started to caress Candy's left tit.
Candy took a sharp breath as Staci pinched her nipple between her fingers.
