"There are going to be new rules in this house." Frank sat on the edge of his bed and stared at his two beautiful daughters. Molly had long brown hair and beautiful green eyes. She had a flat stomach and nice size 32C boobs. Her ass wasn't that big but it was nice and round and perky. Mary's on the contrary, was nice and big, perfect for spanking. She had short dark brown hair and brown eyes. They were twins, but certainly not identical.

 

"Take off your clothes," Frank ordered.

 

"But daddy -" Mary protested.

 

His hand went up as he smacked her across her face. Tears rolled down her cheeks.

 

"I said take off your clothes you little cunts!" They stripped quickly and silently. He stood up and inspected their perfect teenage bodies. They were completely hairless. "Rule number one, you must always be naked while in this house, unless given permission otherwise."

 

"But-" Molly started to speak but Frank smacked her face.

 

"Rule number two, never speak unless spoken to. And now I have something I'd like to show you girls." He led the girls to his office where they were never allowed before. There was a huge plasma TV on the wall, and various labeled boxes piled around the room, with a couch in the back. Frank turned on the TV. On the screen was the girls' room. The camera looked as if it was placed up high because it looked down on their two twin beds. "I will always be watching you." He grabbed the girls roughly by their wrists and practically dragged them to their bedroom. "Stay here," he said, closing the door behind him.

 

He came back with one of the boxes labeled “Leather”. He grabbed Molly and threw her on her bed grabbing her left wrist and using leather handcuffs from the box her cuffed her to the bedpost. He did the same with her other wrist and spread her legs as wide as he could and used leather straps from the box to fasten her ankles to the foot of the bed. Mary stood there terrified as her father ran his hands all over her sister’s body.

 

“Mmm. You’re my little slut now, Princess.” He traced his fingers over her nipples, pinching them softly. She squirmed in her bonds. He turned to Mary, “Doesn’t she look delicious all tied up?” Mary immediately looked away. He grabbed her by the hair and pulled her close to his chest. “I asked you a question, cunt.” Mary squirmed trying to loosen her father’s grip on her hair. “Doesn’t she look yummy?” Frank asked louder. Mary nodded. “Doesn’t she?” he asked even louder.

 

“Yes,” she mumbled.

 

“Yes, who?” he yelled.

 

“Yes, daddy,” she said quietly.

“That’s right you little bitch. You better answer me right next time or you will be severely punished.” He pushed her towards her sister who looked scared out of her mind. He stood behind Mary smiling down at Molly. “Touch her,” he said with an over-powering tone. The way he said it sort of aroused Mary, which caused her nipples to harden. Frank reached over her shoulders and rubbed her pink nipples between his fingers. “You like the sight of seeing your sister naked, don’t you, slut?”

 

“Yes daddy.” There was something about the way Frank talked to Mary that could make her do anything that he wanted.

 

“I want you to feel her pussy.”

 

She reached out and slid one finger in between Molly’s lips. Molly gasped.

 

“How does she feel, princess?” Frank asked, now pinching Mary’s nipples hard.

 

“She’s wet, daddy.” Mary pulled her finger to show her father her sister’s juices.

 

“How does she taste, baby?”

 

Mary slipped her finger in her mouth. “Good, daddy.”

 

“Mary, princess,” Frank said with an evil smirk on his face.

 

“Yes daddy?”

 

“I want you to lick your sister’s pussy for me baby.”

 

Mary hesitated and Frank grabbed her by the hair and shoved her face into her sister’s soaking cunt. He took Mary’s wrists and cuffed them underneath Molly’s back so she was stuck with her face between Molly’s legs. “I said lick her, slut!” Frank yelled as he gave Mary a hard slap on the ass. Molly let out a soft moan. “That’s right, Princess. You know you like your sister to eat you out.” He walked up behind Mary, pulled down his pants, and slowly parted her ass cheeks. He shoved his dick hard into her tight pink ass. She screamed. “Shut up, cunt!” he yelled and gave her ass another slap. He pounded his dick into her ass hard causing her face to be shoved straight into Molly’s snatch. He let out a soft grunt and slapped Mary hard on the ass again. Molly tensed up as she was about to cum. Mary kept licking, sucking, tongue fucking that little bitch’s cunt. Molly screamed as she came, loving ever inch of her sister’s tongue. As Molly screamed, Frank came into Mary’s now stretched out ass hole. He pulled out, un-cuffed Mary and picked her up, careful not to let any of his cum drip onto the carpet. He placed her ass on Molly’s face. “Lick her clean, slut.” Molly obediently licked at her sister’s ass hole, while Frank prepared Mary’s bed for her. Once all his cum was cleaned up, Frank walked Mary over to her bed and cuffed her face down, with her legs spread wide. “Get a good night sleep my princesses. We have a big day ahead of us.” He smirked, and then put his pants on, taking the box and locking the door behind him. Leaving the girls alone in darkness.
