'don't scream and don't bite. If you do, i'm going to fucking kill you' he whispered in my ear. I felt a sharp pain as he pulled off the tape from my mouth. I felt him turn my head and his dick was next to my face. I instinctively opened my mouth. I would do anything he said. I wanted to do anything he said. I put the entire dick as far as I could in my mouth and kept sucking it. I would take it out and lick the shaft and the tip and put it back in and suck. I now wanted to make him feel good. I wanted to make him feel the way he made me feel. I heard the vibrator turn on again and it was against my clit. He was using the vibrator on me while I was sucking him off.
I loved watching my sister lick me off. I could tell that she loved it. She kept pushing my dick in as far as she could and she even almost gagged a few times. I felt her small soft tongue swirling around the tip of my dick. The vibrator encouraged her to make me feel even better. As I was rubbing the vibrator around her clit, I slowly slipped the pen shaped vibrator into her cunt. Her mouth gasped. I slowly moved the vibrator in and out of her pussy and I could tell that she was having a hard time handling it all. I moved down and began to lick her clit again while I fucked her cunt with the vibrator. Her body was shaking and her titties were moving. 'Im going to cum, oh my gosh, i'm going to cum. Fuck fuck I'm going to cum.'
I took the vibrator out before she could do anything. I heard her cry after losing the vibrator. 'Do everything I make you do and remember if you try anything, I will fucking kill you' I whispered again in her ear as I removed the ropes from her arms and legs. She nodded. I guided her to the bathroom and made her stand in the shower. Her legs were wide apart, ready to take whatever I gave her. I could see her pussy glistening from her juices. Her thighs were covered from her dripping pussy. Her pussy was so swollen and pink. Her breasts were shaking. I turned on the shower head and directed it toward her pussy and moved it around the way she did when she masturbated herself in the shower.
'You like that? Is that how you do this to yourself?'
She nodded, biting her lip to keep her moans in. As I directed the shower head at her, I put my finger into her drenched pussy. Her pussy was tight but my fingers just slipped right in. Her pussy tightened around my finger as I tried to pull it out.
I heard him step into the shower. I went from feeling extreme pleasure to being struck with fear again. I was afraid of his dick. I knew that it was huge from the blow job I had given him. I had never had a dick inside me and I was afraid of what was going to happen. He tenderly kissed the back of my neck and shoulder. He then propped on of my legs on top of the shower side, widening my legs. I knew what was going to happen. He told me to be quiet again. He continued to use the shower head against my clit and I felt his dick slipping between my legs. First he rubbed back and forth between my legs. I felt my pussy moisten up more against his cock. I began to rub myself with him. I was afraid but I was turned on. I felt him put the tip of his cock in the opening. I gently pushed down and let him come inside my pussy and I felt completely filled. He did slow and long strokes and my pussy felt on fire.
Her pussy was so tight and soft inside. It was so easy to get inside her because she was so wet. Her body was so tiny. I held her waist and kept slowly pushing and pulling my dick from inside her. My dick was throbbing from hearing her moans. Her hands were against the wall in front of her, helping her stand up from the pleasure. I turned the shower head off. I needed to enjoy her pussy more. I moved her back to the bed, and turned her on all fours. I loved seeing her pussy and her ass. I moved my dick to her beautiful pussy and kept pushing and pulling. I felt her pushing herself against me, burying my dick with her hairy pussy. I went harder and harder, pounding her cunt. She felt around the bed for something and found her vibrator. She put it against her clit and she began to scream from pleasure. I put my hand over her mouth and pounded her harder. I didn't want my parents to walk in on me fucking my sister on all fours. I felt her body start to shudder as she came on my dick. On her brother's dick. I felt her get weak as she laid face down, but this just turned me on more. Seeing her weak helpless body just taking my dick. I pounded my dick into her throbbing pussy and I felt it all burst. My body shook. I let every drop get into her throbbing pussy and then pulled my dick out, stuck my finger into her pussy. She sucked the mixture of pussy juice and my cum off my finger. I turned her around and let her pass out and went back to my room. I will be doing this again.
********
I woke up the next morning feeling my pussy sore. I remembered the fear and immense pleasure I felt yesterday. I went downstairs and saw my brother cooking pancakes. He gave me plate 'Just for my sister' and smiled at me. Suddenly I realized and instead of disgust, I felt my pussy get wet and start to throb. I wanted him inside me again.
