How I Became Big Sister's Sex Slave

... slid off of me and stood up. "Stay right here, don't move, I'll be back in a second." Watching my sister's perfectly tight, round little ass bounce as she walked out of the room, I felt my cock stir and come to life again, stiffening in appreciation of the sight. I lay there in a daze, unable to believe what had just happened. After a few minutes, Karen came back holding a couple of lengths of kitchen twine in her hand and smiling wickedly. "Woah, wait a minute, what are gonna do with that?" I asked. Karen just laughed. "Don't worry Brian, I promise, you'll love this game." Before I could quite register what was going on, my sister had grasped both my hands and tied them securely to either side of the headboard bedposts. I lay there on my back, hands lashed tightly above my head, helpless and under my sister's complete control. my cock throbbed with eager anticipation even as in another, more rational part of my mind I was a bit scared. Karen reached down and squeezed my erection lightly. "Hmmm, it looks like you missed me while I was gone." Then she glanced up at me. "You look good this way Brian, bondage agrees with you."

God yes, I wanna suck your tits so bad, Karen, please!" I panted. Again that soft, throaty chuckle. "Good boy, you learn fast. Go ahead Brian, suck your big sister's titties, make me feel good." She leaned forward and pressed her tits against my face and slid them back and forth as I sucked first one then the other hard nipple into my mouth, swirling my tongue around it, tasting the musky sweet flavor of her pussy. After a few minutes of this Karen pulled back slightly, positioning herself so that she was straddling my waist, holding her pussy just above my hard and throbbing dick. "What else do you want, little brother? Do you want to fuck me? do you want to feel your sister's hot, wet pussy sliding up and down your shaft, squeezing it, making you cum? Is that what you want?" Karen whispered. "GOD!! YES, YES!!" Tugging uselessly at my restraints, I bucked with my hips trying desperately to plunge my cock into her hole. Smiling, Karen slapped me gently across the face. "Who's in control here?" she demanded. "You are, Karen." "That's right. You'll do whatever I want, ...
