Page 6 of Brother's Little Birthday Girl

“I’ve been waiting a long time for this, baby sister,” I tell her as I push the front of my pants down and my cock juts out between us. The tip is already wet, and I smear it against her thigh.

“Don’t,” Dad says sharply, and I look over at him. “I’ll give you whatever you want. You want money? I’ll give you anything. Just don’t do it.”

“Knox,” Layla says softly, and I turn to look down at her. She kisses me softly before looking into my eyes. “I want it to be you.” She reaches between us and guides my cock to her opening. “I’ve always dreamed of you being my first.”

“Your first and last,” I tell her as I sink inside her pretty pink pussy.

She’s so goddamn tight it makes my eyes roll to the back of my head. I thrust forward in one hard rush and grunt when I’m all the way inside. She cries out, and I try to go slowly, but I’ve never, ever felt anything so fucking good.

“Holy shit,” I breathe as I thrust in and out of her wet little slit. “Fuck. So good. Tight. Wet.” I can hardly get out words, but I want him to know what he’s missing. “Fresh little cherry.”

Somewhere in the back of my mind, I can hear our father struggling to get out of his chair, but it’s no use. The more he fights it, the tighter the zip ties will get.

“Knox, you feel so good.” Layla moans and wraps her legs around me. “I needed you inside me for so long.”

My cock swells at her dirty words, and I tell her to keep going.

“I was so empty I ached. I needed you right here.” Her fingers move between us, and I feel them on my cock as it enters her.

“Now you’ll need it all the time. Once you get a cock in you, you’ll be begging to be filled all the time. As soon as I cum in you, you’ll be searching for more.”

I look over at Dad and wink. That sends him into another round of rage, and he shouts in anger.

“Daddy, he feels so good.” Layla is taunting him as she rocks her hips to take me deeper. “He’s so big and hard.”

“Pull that dress down. I want to suck on your nipples,” I tell her, and she does it. As soon as the pretty little buds are out, I hungrily lick and suck them. It makes her moan louder, and I don’t know how much longer I can last.

Layla and I have always been in tune, and like she can sense I’m close, she goes right to the edge. Her back arches and her thighs tense as she clenches around me hard. I thrust deep one last time as I watch her cum on my cock. Her blush starts just above her tits and then spreads up her neck and cheeks. Her orgasm goes on for so long, and I feel every pulse of her pussy on my shaft.

The way she milks me is obscene, and I have no choice but to cum inside her. My cock throbs as I fill her little pussy up, and she keeps begging for more. I cum and cum until it’s running out between us and I have to use my fingers to scoop it up and smear it across her belly.

She’s a mess by the time I’m finished, and when I pull out, there’s a rush of it that comes out too. I push it back in her as well as I can, and then I get up off the futon. My cock is still hard as fuck and jutting out in front of me, but I ignore it as I walk over to where our dad is seated. I hold my hand out in front of his face, and he looks up at me.

“I know you want to taste her,” I say to him, and he looks down at my fingers that are coated in the both of us.

He opens his mouth, but before he can either get a taste or tell me to fuck off, I open my palm and smack him across the face with it. It’s so hard his eye is immediately bloodshot, and it takes him a second before he can focus on me again.

I bend down so we’re face to face as I look at my father for the last time. “That’s the only taste of her you’ll ever get.”

When I turn back around, I button up my pants and then reach for Layla. She’s wobbly on her legs as I help her put her dress back in place and then pick her up in my arms. Neither of us says another word to our father as we leave. I’m sure someone will cut him free. Eventually.

“What’s going to happen now?” she asks when I carry her from the treehouse.

“I’ve already got your bags packed. We’re leaving, and I’m taking you home.” I kiss her forehead, and she snuggles close.

“Home.” She sighs contentedly, and I squeeze her in my arms. “I like the sound of that.”

THE END!
