Page 9 of Their Dirty Girl

I moved my tongue from her sweet slit to her cherry anus. Without hesitation, I licked her tightest hole before dipping my tongue inside. Fuck, even this part of her tasted good.

“Yes, Brother. More. I need more!” she cried out as she thrust her plump ass back at me. I knew if she was any louder, she’d wake our dad up.

“Look at you, Mary, begging for your brother to tongue-fuck your asshole. If only Mom knew what a whore she raised.”

“What Mom did to Daddy was so wrong. The least I can do is make sure he’s taken care of. I can’t let any other woman have him—or you. I don’t want you or Daddy to go anywhere else for what you need.”

I curled my hands into her ass cheeks and rimmed the tight hole between them.

“Anything you want, I’m here, Landon. I have three perfectly good holes for you to use whenever you want.”

Mary’s words drove me crazy.

As much as I wanted to tease her, I needed my cock buried inside her. Without giving her warning, I rose, stroked myself, and aimed the tip at her anus. With my hands on her waist, I curled my blunt nails into her flesh until she hissed.

But before I shoved in deep, I gathered another mouthful of saliva and spit it on her asshole, getting it all nice and lubed up. I pushed the saliva inside and finger-fucked her a few times before placing my cockhead at her hole.

“Get ready. Big Brother is going to fuck your ass and fill you with his cum.” And with that, I shoved my dick all the way inside, gripping her hair and burying her face into her pillow to muffle her scream of pure agony. I wasn’t even slightly gentle. This was years of pent-up desire for my little sister finally being unleashed.

I leaned over her, my chest to her writhing back, my eyes nearly crossing as she fought against my weight, and I growled in her ear, “After I fuck this ass good and hard, I’m going to split your dirty cunt in two, Mary. And I’m not going to be sweet. Ever. But you’ll never tell me no. You’ll always be so eager for Big Brother to fuck you. You’re your family’s whore now.”

The next day

It was impossible to concentrate at work. All I could think about was Mary and being buried in her sweet pussy again.

I should’ve felt bad about fucking my daughter. Part of me knew it was wrong, but nothing in my entire life had ever felt so right.

She was all I could focus on all fucking day. And so when I got off work and got home, seeing her car in the driveway, I had one goal in mind.

To fuck my baby girl.

I strode down the hallway to Mary’s room. I didn’t even care if she was ready for me. I was going to fuck her and drain my balls.

I was going to fuck her until she was full of me.

I had my hand on her doorknob and was about to push it open, when I heard her loud moans. My cock was harder than ever as I pictured how her legs were probably open wide as she played with her cunt again. I bet her fingers were in her pussy right now as she fucked herself to thoughts of me. I loved that she was so filthy.

“Baby girl,” I said through the closed door, “I’m ready to give you another dose of Daddy’s hot cum.”I pushed the door open then, and what I saw had my every muscle tensing, this sudden rush of heat and adrenaline coursing through me.

Jesus Christ.

My sweet Mary was on all fours as her brother fucked her. They were so into screwing each other they hadn’t heard me come into the room.

“The fuck?”

Hearingthosetwo words barked out, both of them stopped and glanced over at me, but no shame was written on either of their faces. No one spoke for a long moment before Mary moaned and smiled at me over her shoulder.

“Oh. Hi, Daddy.” She glanced at Landon.

My response came out without thought. “You letting your big brother fuck your tight little snatch, sweet girl?” I was a dirty, sick bastard, because my cock grew even harder.

“Landon saw us fucking, Daddy, so he came in last night and fucked me too. I was eager to show Big Brother I love him too.” She looked back at me, her big tits shaking as Landon started thrusting in and out of her again.

“That’s right, Dad. I saw you filling up my little sister’s pussy with your cum, and it made me so fucking jealous that I had to sample her cunt too. I had to fill her up and mark her as well.”
