It began one day when I was feeling really horny in class. I had only General Studies in the afternoon so I decided to skip the afternoon and go home, knowing I could masturbate. Dad and Steve, my elder brother, were out at work, Lucy, my younger sister was still in class. Our Mother had left us years before and had not been seen since, though I suspected Dad had some idea. I didn't often do that, skip school to bring myself off. I had once before, but it wasn't a regular thing.
After I reached home I decided that I would sneak one of Dad's dirty videos and watch it. I felt bad about skipping school and taking the video but the forbidden was fuelling to my arousal. Upstairs I undressed quickly and put on my new grown up satin wrap and padded downstairs. I could feel my lips thickening and my nipples hardening as I found the videos and choose one. Bobby our Alsatian wanted to play so I shut him in the kitchen and sat on the sofa in front of the TV. I'd seen it once before but that didn't matter, it really turned me on. Soon I had opened the robe and was squeezing my tits and rubbing my clit. I was laying back wantonly and my legs had spread out wide. It was all too much, my original sexual frustration, the naughtiness, the feeling of giving in to my lusts and the sights in front of me. My fingers felt so good on my tits and sliding around my wet cunt. I came once fairly quickly but knew I could get a better one. As I concentrated hard on the thread of the next it just grew and grew, it was going to be a big one, I could tell.
Then it began to overtake me, I was falling, falling into the abyss, over the edge. Oh God! I felt Bobby between my legs. I saw his hairy back between my legs, I could feel his cool wet nose on my thigh and his muzzle at my cunt, but it was too late. I tried to push him away but it was difficult in the position I was in and I started coming. Fireworks were exploding behind my eyelids and it ripped through me. Bobby must have thought I was playing and he had lifted his paws up onto the sofa. As I was coming round I tried to push him down again but more lights were in my eyes. It took me a few moments to realise that these weren't coming from my orgasm!
I looked up to see Steve standing taking photos of me! Frantically, almost crying, I pushed Bobby away and Steve dashed out of the room. Without thinking to cover myself with my wrap I chased after him with Bobby bouncing up the stairs with me. His room door was locked. I banged frantically on it with no result before realising that I was naked and dashed down for my wrap. Still he wouldn't come out or answer. Finally I slid down the door and cried, the realisation of what he must have seen dawning on me. He wouldn't answer me so I went downstairs and put away the video and then put on some clothes.
Steve finally appeared at the door of my room. I had decided that I was going to give him hell but knew I wasn't exactly on safe ground. When he stood there leaning on the door jam all I actually did was blush as I looked up at him. Eventually Steve broke the silence and told me to look on my email. There was something in his voice. With that he went and I could hear him going downstairs.
Numbly I opened my computer and watched as the list of emails appeared. The last one was from Steve. The message simply read - 'open the attachments and come and see me'. I did and couldn't believe what I saw!
They were all photos from downstairs. The first showed me sprawled on the sofa, legs splayed, with my fingers obviously at my cunt, my eyes closed, my gratification obvious. The next were even worse! Bobby was now in the frame. His muzzle was between my legs and although I knew I was trying to push him away it actually looked as though I was holding his head to me! The next one looked as though he was either about to mount me or already had and my mouth was open as I orgasmed. The final one showed my face looking directly at the camera in a state of shock with Bobby still over me. As I looked at them I could feel cold sweat covering my face. I couldn't believe it. It looked really bad. He must think I was twisted or something. It was so awful that he had seen me like this. If anyone else saw these I would die! I'd never be able to face anyone ever again! I didn't even know if I could face Steve. I just didn't know what to do. I sat there in a state of shock and just didn't know what to do. In a daze I turned off the computer and went downstairs.
Steve was in the kitchen sitting drinking coffee at the table.
"Steve that's disgusting I can't believe you did that!" He just sat looking at me and drinking his coffee. "Look it wasn't what it looks like." I was blushing scarlet.
"What does it look like Sis'?"
"Steve!"
"I take it you didn't expect me to take the afternoon off as well."
"Steve! You let Bobby out didn't you?"
"Yes, yes I did. You do realise that I could send these to all sorts of people? My friends, your friends, even put them on the web."
"You couldn't! You wouldn't! Steve! You wouldn't do that would you! I wouldn't be able to look at anyone ever again! Steve! Don't, I'll do anything."
"I know you will."
"What do you mean?" I felt a sudden tightening in my stomach. I felt strange.
"It means, Sis', that you are going to be real nice to me from now on. You are going to do all I tell you or you will be seen by lots of people who are shocked."
"I'll be nice to you Steve."
"Yes I know. You can begin now. Suck my cock."
"What! You're my brother! I can't do that!"
"Start believing. My prim little Sis is going to be really bad for me!"
I couldn't believe it! It took me a long time to take it in. We sat there in silence as what he was really demanding sink in. What was all too apparent to me was the strange feelings that what he had said had ignited in me. Steve eventually got up and made us both of us a coffee before speaking again. He told me to begin. Tears could be felt in the corner of my eyes. Eventually I realised I had no choice. I got up and stood, then knelt before him. I couldn't believe I was doing this. I'd only done it once before with a boy. Slowly, as if hoping that it would all stop and I'd wake, I began unzipping his trousers. I opened them up and fumbled to get his erect cock out. He was certainly turned on by me, by what he'd seen. The smell of his masculinity hit my nose. This was my brother! I held it in my hand tentatively, then moved my hand up and down it. It was certainly not a small one.
"Come on Sis, in your mouth."
I moved forward and kissed the knob. It twitched and I pulled back. He scowled at me and I continued. I licked it once, and then resigning myself to it I carried on, finally taking the end into my mouth. He shuffled a bit in his chair to get comfortable and it went in deeper. His fingers curled into my hair and moved my head up and down. I couldn't take much, only about half of it at the most with my fist around the base but he was obviously enjoying it. It felt so big filling my mouth.
Suddenly he told me to stand and let him see my body. At first I was going to argue but I knew he had seen it before. After a while I struggled out of my jeans ridiculously ensuring that my knickers didn't come down at the same time, before shrugging my T-shirt over my head. Then I had to remove my bra and knickers too. It was really humiliating. He also made me take a swill of my coffee and hold it in my mouth before continuing. The coffee must have heated up my mouth, when I took him inside again he let out a groan. I thought he was going to come then but he didn't. He carried on moving my head up and down on him. It began to be a kind of routine and my mind wandered to the cocks in the video and that I must look like some porn actress kneeling on the floor naked. I was so ashamed but kind of hot too. He passed my coffee to me a couple of times more as I sucked him, so my mouth was hot around him, and though I am ashamed to say so, I got into it as well. I could feel him holding back but then he started coming in my mouth. I couldn't move away, he held me down on him as I felt his spunk spurting out into my mouth. At first I gagged a little and thought he would let me off but he held me there until he was through. I just had to adjust to it and swallow. He tasted kind of salty but it wasn't much like anything other than spunk.
