I climbed onto the bed and sat beside my sister. I was now naked from the waist down, and trembling with need. I wanted to cum so bad. My fathers hand was still in my hair, and suddenly I found myself thrown forward into Karen's chest. "Suck your sisters titties," Daddy ordered. I reached out and drew up her nightgown which was now bunched around her waist. Her large breasts hung there - right in front of my face. Suddenly I wanted so bad to suck my sisters titties. I bent down and sucked a nipple into my mouth. I heard Karen moan, and felt her push her chest toward me even more. "That's a good girl," Daddy whispered in my ear. "Make your sister happy, and it will make Daddy happy."
I could feel Karen's hand still pumping in and out of her pussy, and without being told I reached down and replaces her hand with my own. She was so wet, and it felt so strange to be touching another pussy. She cried out and humped against my fingers, as I slid two into her over and over. My mouth was still on her nipple - now biting and pulling. It was hard as a rock in my mouth and I moved to the other one. I felt Daddy's hand on my head again, and he pulled me into a kneeling position. My naked ass was again in the air, and I felt my Daddy's big fingers run over my little gash. I moan with Karen, and pushed my bottom back to my Daddy at the same time I added a third finger to her wet cunt.
"You are such a slut Becca," Daddy said. He used my hair to pull me back from Karen's titties. My head is back in the air now, and I'm trying so hard to get the fingers rubbing my pussy lips into my cunt. "What so you want Daddy to do to you Becca?" I heard Karen ask. Her own hand had move back to her pussy and rubbed her clit as I continued to thrust in and out of her.
