I blackmailed my sister
My name is Tony and I live with my parents and sister Kerry. I arrived home early, about 1pm and as I entered I heard noises coming from Kerry's bedroom, at first I thought she must have left her radio on and went to switch it off. The door was open a little and as I got closer I realized the noises I heard were Kerry's, I looked around the door and saw Kerry on her bed getting truly fucked good and proper by a boy who was about the same age as her. They didn't notice me, the amount of noise Kerry was making I guess stopped them from hearing me come in. I watched them for a while, until now I can honestly say that I have never had any sexual feelings for Kerry, she was my sister after all, but seeing her naked, seeing her getting fucked made my prick rock hard. An idea came to me, I would take a couple of pics of them, they would be nice to keep, to remind me of today. Quietly and quickly I took a dozen pics. Boy were they good. I had a great one of Kerry with his cock down her throat and others showing her getting fucked. I left the house like I had not come home yet. Mum and dad were going out tonight, Kerry was supposed to be finishing her homework, I said I would stay in and also be doing some work on my computer. Mum and dad left. After 10 minutes Kerry came out of her room and turned on the television, I sat opposite her and looked at her. After this afternoon I was seeing her in a different way, she was very pretty, she had shoulder length blonde hair, and now that I had seen her naked I know that she has a nice pair of tits, she is slim and the little bit of blonde hair she has at her pussy was hardly noticeable. She was now wearing a pair of jogging shorts and a baggy top; she had her feet curled up underneath her as she sat on the sofa. "Tony, will you quit staring at me" she said, I was deep in thought and she caught me staring, in my mind I pictured her as I saw her this afternoon only this time it was me who was fucking her. "Sorry" I said, I was thinking out loud when I asked, "what did you do at school today", she told me to mind my own business. It was then that I came up with my plan. I said "I've got something you might want to see", I got out my phone and started swiping through the pics for her to see. "What do you think? They are good aren't they?" Kerry silently looked at them, her face reddened, "You bastard Tony, is this how you get your kicks, by spying on your sister?" She was going to delete them until, "don't worry" I said, "I've got these downloaded on my computer too. I was thinking what dad might do if he was to see them, probably send you to aunt Jessie's". "Just think Kerry, a farm in the middle of nowhere, no friends, no cable TV, no nothing". "Please Tony" Kerry was now pleading, "don't show them to dad, you know he will freak out, I don't want to go to aunt Jessie's". "OK, but there is something you will have to do for me in return" I said. Kerry had now calmed down, she thought for a second and said " tell me what you want me to do then, what is it, your chores?, clean your room?, I'll do anything but please, promise me you won't show any of those to dad" "There is only one thing I want from you Kerry", "Just name it and I will do it" she replied.
"Ok, I want to have sex with you, I want to fuck you like when I saw you this afternoon!" "NO WAY!" she shouted, "you are my fucking brother for Christ's sake, no fucking way!, I'll tell dad what you said, what you wanted me to do". I went over to her and sat next to her, she shuffled herself to the far end of the sofa. "Kerry, in two months time I start university, I'll be gone from here, if I left tomorrow it would be no big deal for me, I've got plenty of people I could stay with till then, you on the other hand would end up at aunt Jessie's for sure, you do what you want to do, all I am saying is dad does not need to know if you play ball". She went quiet as if she was thinking about what I just said, and then she started to cry. "You shouldn't be asking me to do this Tony, it isn't right for a brother and sister to have sex, it's just not right. "Look Kerry, it's no different to what you did this afternoon, what difference does it make to you if it is me fucking you or the boy you had then? I'll tell you what, mum and dad are out again on Saturday night, I'll give you till then to make up your mind what you want to do, if you don't do what I want dad will see these Sunday morning". She pleaded with me again asking me not to make her do it, I said I wouldn't change my mind and I told her that I wanted an answer at 8 o'clock on Saturday night. She got up to leave the room, as she was going out the door I told her to wait, she turned to me, "I want to see you wearing something sexy on Saturday, I want you to wear something hot, and I want you to shave your pussy smooth", she turned and ran to her room. For the next two days we both stayed out of each other's way. I didn't see much of Kerry on Saturday, mum said she had gone into town, mum asked me if I had any plans for the evening, I told her I didn't and that I would probably stay home, she said that Kerry was also staying in tonight, Kerry had told her she was going to have a hot bath and an early night. Mum and dad left about 7 o'clock, they said they would be back about midnight. I went to my room and played about on my computer. 8 o'clock came and there was no sign of Kerry, I would not have given the pics to dad anyway, I didn't want to make trouble for her, I really cared for her as a sister but after the other day I had become infatuated with the thought of having sex with her.
There was a knock on my door, I opened it, she had on a very thin long white top, no bra. her tits seemed bigger and through the material you could make out the darkness and shape of her nipples, she didn't seem to have on any panties. Her blonde hair was tied back in a ponytail and she wore bright red lipstick. I took her hand and led her to my bed, I sat her down on the edge of my bed and sat next to her, my arm going around her shoulder, my other hand resting on her leg, "Look Kerry, if you think of me as being someone else and not your brother maybe you will feel different, you never know, you might even enjoy it!" I used the hand that was around her shoulder, I turned her head so she was facing me and kissed her, at first she kept her lips shut tight together, then after a little while she gradually opened her lips, my tongue darted into her mouth, I moved my hand that was on her leg up over her top and cupped her tit, I began to play with it and rub her now hardening nipple. I didn't think she would but she slowly started to respond, her tongue now explored my mouth and she put one arm around my neck, she pulled me closer, kissing me deeper, I slid my hand under her top, over her stomach and up to her tits, they felt firm and so smooth, I cupped them, squeezed them, I used my thumb and forefinger and tweaked her hard nipples. She was either a good actress or she was actually starting to enjoy what I was doing to her. I stood up, removed my shirt, and took off my jeans and shirt, my prick stood out hard, she had her eyes fixed on it, I asked her to take off her top and she quickly pulled it up over her head. She was naked now. She had done what I asked her to do her pussy was shaved smooth. "I want you to fuck me Tony, I want you to fuck me hard and deep", I looked into her eyes that were filled with lust. I know that we shouldn't do this but I don't care any more, I want you Tony, make love to me, fuck me, fuck me like I have never been fucked before!" My prick was hard, "I really do love you Kerry, I am sorry that I forced you into this, I wouldn't have given dad the pics, please believe me." "I'm glad it happened" she replied, "now, don't waste time, mum and dad will be home soon, just fuck me good." She lay back on the bed, legs open. I positioned myself between her legs and slowly slid in my prick until I was deep inside her, I began to fuck her, slowly at first then deeper, harder, faster. She was crying out "fuck me, fuck me hard", she couldn't get enough, I wanted to last longer but I couldn't, then with one deep lunge I came inside her, I felt my spunk shoot out, filling her tiny pussy with my spunk, I collapsed on top of her and kissed her, my prick twitching and throbbing inside her. We rolled onto our sides, kissing each other, I looked at the clock, it was gone 11, time for each of us to have a quick shower before mum and dad got home. We showered together, Kerry sucked me off in the shower and she kept my prick in her mouth when I came, boy did that feel good! We were both in our own rooms when they got home, I know what I was thinking about lying there on my bed, I wondered if Kerry was thinking the same thoughts.
For the next eight weeks before I went to university Kerry and I had sex as often as we could, we talked about what we were doing and both of us agreed it was what we both wanted. I have been at university for three months now, we text each other regularly and we are looking forward to seeing each other and more importantly fucking each other as soon as I get the chance to visit home. Kerry has promised me her pussy will be smooth, as she knows I like it that way, I can't wait.
