Bill had been living with just his daughter and step-daughter ever since his wife had left him for a younger man. He didn't have a lot of money so Candy (his daughter) and Staci (his step-daughter) had to share a bedroom. They were both eighteen and seniors in high school.
Candy was tall with long blonde hair that went all the way down to her firm ass. Her tits were a full C cup and she had perky nipples that were often peeking through her tight tops.
Staci was medium height with dark black hair shoulder-length hair. She had rather large D cup boobs as well as a tight little ass- probably from being a cheerleader.
He often wondered if they shaved their pussies and would imagine their wet hairless cunts when he masturbated at night.
Staci and Candy were rather playful and liked to tease him. At first he thought it was just a coincidence but then he realized that they did it on purpose.
They always seemed to want to do their aerobic excercises when he was in the living room. He would watch them in their tight sports bras and short shorts bouncing up and down while they ran in place. Occasionally he would get an upclose view of an ass crack if they did toe touches in his face and when he would see their pussies pushing against their gym shorts he couldn't help but get excited.
This day started out like any other:
Bill was downstairs making breakfast when he heard the girls coming down the stairs.
"Hi Daddy" they both called. Staci had gotten into the habit of calling him Daddy and he couldn't help but enjoy it.
He turned around and saw Staci standing there in a towel that barely covered her ass, with her hair dripping wet. Candy had on a very short black skirt and he could see her thong sticking up in the back. She had on a tight white t-shirt with no bra and her nipples were at attention. She was also wearing thigh high boots.
"What's for breakfast?" Candy asked as she leaned over and kissed her father on the cheek. She also rubbed her breasts against his arm in the process.
Bill felt his dick already started to stiffen as he answered "eggs and bacon and toast- your favorite."
"Mmmmm...yummy." Candy sat down at the table and her father brought her over a plate.
Staci braced herself against the counter and jumped up to sit on it. "Dad I can't eat all of that fattening stuff! I have to stay in shape for cheerleading"
Bill turned to look at her and saw that she was sitting with her legs spread wide open. Well, now he knew at least one of his daughters had a clean-shaven pussy! He tried to casually glimpse another peek between her legs but he saw Staci meet his eye and he knew that she had seen what he was doing. Instead of yelling at him she leaned back and spread her legs further and licked her lips. Bill's dick jumped in his pants.
How could they keep doing this to him?
Candy looked up from breakfast and half shouted at Staci, "Staci, you slut, close your legs! Daddy shouldn't be looking at his dirty little daughters like that."
Staci pouted and jumped off the counter. "I'm going upstairs to get dressed." She stomped up the stairs while Candy rolled her eyes. "She's such a drama queen! I'm going upstairs too to finish doing my hair and makeup."
Once the girls were gone, Bill started thinking about seeing Staci's sweet pussy. He wondered if she'd ever been fucked. "Of course she has", he thought to himself, "look at her!" He slowly started to stroke his dick through his pants, while imagining his step-daughter riding the dick of some faceless guy, bouncing up and down on his hard shaft while she squeezed her own nipples and moaned. Bill closed his eyes while he kept this fantasy going. He unzipped his pants and started to stroke his dick faster as he imagined her moans getting louder and louder...
Suddenly, Bill opened his eyes wide. Either his fantasy was getting really intense or he was hearing moaning coming from upstairs!
He zipped his still hard dick back in his pants and went quietly up the stairs. When he got to his daughters' room he couldn't believe what he was seeing. The door to their room was half-open and Staci was laying naked on her bed with her legs spread wide open. That would have been hot enough on its own, but there was more. Candy was on her knees at the foot of the bed with her face buried in Staci's pussy! Staci was moaning and writhing as Candy ate her after breakfast dessert. She was pinching her own nipples.
"Oh Candy, I love the way your tongue feels in my pussy. Eat my pussy Candy, eat me!"
