Destroy her Cunt

Dana's pussy is slick as your cockhead presses against her pink lips. She looks back, breaking away from Clair's lap, her blue eyes wide with fear. In one violent motion you thrust into her tight virgin body, only able to fit a few inches deep. Dana cries out, wincing in pain. You dig your fingers into her hips and thrust hard into her forcing half of your cock into her tight hole. Your sister tries desperately to squirm out of your grip, pushing against your thigh with one hand.

"No! Please! Use Clair! Use Clair!"

You grab the hand that's pushing you away and yank it up to her back pinning it against the small of her back and thrust again, getting a few inches deeper. "Shut up." You growl as Dana collapses, her face hitting the floor with a dull thud. "Be glad I'm not keeping you chained up like your little friend." You pull out of her entirely then slam your full length into her. She screams. "Thank me." You growl, relishing the feeling her untouched pussy sucking you in.

Dana sobs wordlessly as tears run down her cheeks.

Leaning forward you grab both of her pigtails and yank back, forcing her neck back as she fall completely prone. Your cock pops free for a moment but you quickly slam back into your sister's tight little cunt. "I said thank me!"

"Th-thank you." She squeaks.

You begin your full **** on her pussy, thrusting in and out of her with a wet slapping sound. "You're welcome little sister. Now thank me for **** you."

"Thank you for **** me big brother." She cries.

When you feel like you're reaching your limit you pull out, panting and flip Dana onto her back. Your helpless little sister stares up at you her lips trembling. You pull her shirt up revealing her tiny tits, two tiny pale mounds topped with little pink nipples. Grabbing her knees you **** them against her chest and lean forward, slipping back into her pussy. You moan in pleasure. "I'm gonna fill you up with my cum Dana."

"Please no." She begs, wiggling and slapping at you with balled fists with renewed desperation.

You look up at Clair and bark, "Help me hold her down." Clair looks conflicted for a second but crawls forward to grab Dana by the shoulders, holding her down.

"No no no no no." Dana cries out as you ravage her. With your balls slapping against her taint you let out a primal growl and release your load inside her. You pant, laying on her legs still pinned against her chest as your shoot spurt after spurt still buried in her cunt.

"Fuck you're tight." You say as you pull out, a white trickle of cum leaking out of your sister's freshly fucked hole.

"I can't believe you did that." Dana whispers.

"Of course. I own you. The only reason I'm not making you a dedicated cum dumpster like Clair is because you're my sister, but when I want to use you I'm going to." You pull your pants up and head towards the stairs. "Now make sure you get Clair cleaned up properly and chain her up. You don't want to disappoint me."
