"Piper, be a good girl for me and go get the black case out of the bathroom please?" Miles asked, as Bailey licked his cock clean. He had just finished unloading into his teenage step-daughter's warm mouth and was eager to continue to discipline Bailey.
"Yes, Daddy!" Piper said as she scurried into the bathroom. When she brought it back to the bedroom, Miles' cock was clean and Bailey was seated in one of the high-backed armchairs. Miles opened the case, and drew out two scarves and a pair of handcuffs. Miles went to Bailey and cuffed her arms behind the chair, and then used each of the scarves to tie her ankles to the chair on each side, with her legs spread.
"Whore, you're going to watch your sister be a good girl. You need to learn obedience and discipline. I am your Daddy, but now I will also be your master, because whores like you need to be controlled for their own safety. Tell me what you are."
"I am your whore, Daddy," replied Bailey.
"Good whore," said Miles. "Piper, come sit on my lap in this chair."
"Yes, Daddy," replied Piper.
Miles walked to the mirroring chair and sat down. Piper sat on Miles' lap, and Miles immediately lifted the sweater up off of Piper. Underneath, Piper was wearing a white lacy bra, and her dusky pink nipples poked through the thin fabric. Miles kissed her again, devouring her mouth. He kissed down the side of her neck, while sliding his hand inside her leggings. Piper jumped as Miles slid his fingers through her slick pussy lips, feeling how wet she was.
"You're so wet for me, baby girl. Who does this wet pussy belong to?" Miles asked.
"You, Daddy. This is your p-pussy. No man has ever touched my pussy, only you," Piper replied. Piper's sweet innocence as she stuttered on the word pussy sent Miles over the edge. He flexed and used both of his hands to rip open her leggings, tearing them off of her. He pulled Piper's back against his chest, one hand playing with her nipples and the other teasing her sweet pussy. He alternated between tracing her pussy lips, dancing over her clit, and lightly rubbing the circle around the outside of her entrance, forcing her to rub her ass against his quickly hardening member. His rod rubbed against both her pussy and her rosebud, and at that moment, Miles knew that he wasn't stopping until he had used all of his girls' holes. That feeling that this was wrong had evaporated, and somehow, he had decided that the twins would always belong to him.
Miles kissed up her neck, nipping her neck, and then kissed her ear. He lightly blew warm air into her ear, and Piper moaned, her pussy tightening against his fingers. Miles watched as goosebumps spread across Piper's arm.
"I am going to take this sweet pussy. But before I do, I want you to be relaxed. I'm going to show you and your sister how a master treats his good girls. Lay on your back on the rug, and use your hands to hold your knees open. If you let your knees close, I will punish you."
"Yes, Daddy. Thank you, Daddy," said Piper.
Piper laid back, and Miles laid on top of her, supporting himself on his elbows. He kissed her again, spearing her mouth with his tongue and grinding his cock against her wet pussy. He kissed down her body, teasing and pinching her nipples. He licked along her stomach, tracing his tongue along her skin as he reached her mons. He avoided her clit, slowly tracing his tongue along her lips and nipping at the sensitive skin. Miles blew his warm breath on her clit, and Piper audibly gasped.
Miles chuckled, and licked his middle finger, leaving as much saliva on it as possible. Miles slowly and gently slid his finger inside Piper. Her virgin cunt gripped his finger tightly and he could feel the slight barrier that was his step-daughter's hymen. He pulled his finger out and used his fingers to spread Piper's lips wide, before he began lapping at Piper's clit and pussy. Miles teased her, alternating between focused licking and sucking on her clitoris and then spearing his tongue inside her pussy. Piper was gasping and crying and desperately holding onto her knees. Sensing she was getting close, Miles wrapped his lips around her clitoris and sucked, humming against the sensitive skin, and just as he began feeling her cum, Miles slid his finger into her ass and fucked finger fucked her tight asshole with just the mix of saliva and pussy juices as lube.
Piper cried out, "Yes, Daddy!" as her legs shook and her pussy clenched. Her pussy gushed her cum over Miles' mouth and chin. Piper was panting, still holding her legs spread.
"Now that's a good girl." Miles said as he looked over Piper's exposed body. Her skin was flushed. Miles' cock jerked as he realized he was about to take his teenage step-daughter's virginity. Miles walked over to Bailey and bent over the chair.
