Blackedmailed my sister

In high school, I got so tired of my friends telling me how sexy my sister was. It did not matter that it was true. It is not something I wanted to hear about Tasha who was, and is, a year older than me. She has maintained her high school figure since graduating 7 years ago as she is overall slender with C cup breasts and a very large butt in relation to the rest of her body. Ours was a very normal middle-class childhood with both parents and two other siblings. In high school, we both had active social lives and many of the same friends. While we both made the honor roll Tasha did not go to college as she fell in love and got married while I went to college and am now a lawyer handling discrimination claims of all types. I should make it clear that I knew my friends were right about Tasha being hot but it still was embarrassing to hear her talked about like that. If I am being totally honest I must admit I did have fantasies about making out with her but never even flirted with her. There would be no need in writing this unless something changed a few weeks back. Tasha and her husband, Ryan, live a few blocks from me and my wife. We come and go from each other’s places freely. Evidently Tasha had forgotten that I told her I would be by this particular afternoon to help her with some legal paperwork. I pulled up to the house and the door was standing open and I could hear two voices the male voice was not Ryan’s as it was deeper than his. At first, I thought nothing of it. As I got closer I heard my sister cry out, „Fuck, deeper Oscar, harder…yes!” Silently I crept in the door and took off my shoes. I looked around creeping in further and then I saw them. There was Oscar, a local politician and our neighbor, fucking my sister while she was dent over the kitchen table. I stood there daze watching his very large cock pummel Tasha’s pussy. Being bisexual, it did not take long for me to become rigid. It was just too much to take between his hard member and balls and especially her bouncing tits and big ass. They did not notice me as I was only five or so feet away when Oscar panted, „Fuck Tasha, you’ve made Monday afternoons my favorite time of the week!” That was it, I had heard enough; lust overtook me. A plan formed instantly in my mind. The plan was not original and was very simple. Tasha had become very spoiled by the life style her husband provided as they were one of the richest families in town. If he found out about this she would be left with absolutely nothing in the divorce and I knew she would do anything short of murder to keep that from happening. Blackmail was the obvious answer even though I knew I would never really tell Ryan about what was going on in his own home every Monday. My feet shuffled silently the last few feet to the couple and I could see my sister’s pussy honey glistening on Oscar’s cock as he worked it in and out. I didn’t breathe as I made my move. First, I grabbed our neighbor’s ass and plunged a finger into his rectum. He looked over at me startled unable to speak. Almost instantly I grabbed one of my sister’s tits and gave it a squeeze as I planted a kiss on Oscar’s mouth. I plunged my finger deeper into his bowels to hold him in place as Tasha was pinned against the table. „Ryan would be very interested to know what you two have been doing on Monday afternoons. Dare I say it Oscar the voters would love to hear about this as well. I can just see the headlines now!” Tasha screamed as she was made aware of my presence. She tried to pull away but was too well pinned and Oscar was too far gone to stop fucking her. „If you two don’t want real trouble you will do whatever I say whenever I say from this second on,” I said coolly as I continued to finger fuck our adulteress neighbor. His stroking was getting faster and my sister was arching her back but still trying to pull away. „That is…blackmail. You wouldn’t do that…to your own sister,” Tasha panted. I removed my hand from her tit and swiped it across Oscar’s cock on the outstroke then licked off my sister’s honey. Oscar did not say a word as he just grunted. „That is exactly what it is and yes I am blackmailing both of you! Oscar this is the last time you will have sex with my sister and you will not cum inside of her. You will, however, cum in my mouth. Now pull out,” I demanded. He just kept fucking her so I pulled my finger out of his ass hole and squeezed his balls until he finally relented and pulled out. „Tasha stay right there while I make your boyfriend cum!” stopping her in her tracks as she had begun to scramble to get away. She already had pulled her silky panties back on but I stared her down and she quit getting dressed. She sunk to the floor beside us as I joined her there . „You fucking bastard why are you doing this?” she demanded as I grabbed Oscar’s cock in my hand. I licked all around the member tasting my own sister’s honey until it was clean. Then I sucked the stiff cock into my mouth in less than a minute I was rewarded with his salty spunk. It was tempting to do more to him but my sexy sister was there and I just had to have her. Just watching her breasts rise and fall with her breathing was turning me on more than I can ever remember. I pulled Oscar to the floor beside her and quickly snapped a few pictures with my cell phone of the two sweaty lovers Shoving the phone back in my pocket I curtly spoke, „Oscar get the fuck out and don’t come back. I’ll let you know what else you can do for me soon.”. Silently my sister and I watched as Oscar got dressed and walked out the front door. At that time, I had no intention of any further sexual trysts with him in the future as that could complicate my relationship as a lawyer with the politician but I could absolutely use my blackmail power to get favors from him. I looked over at Tasha and saw her fidgeting nervously. „What a fucking bastard you are making him do that! And, if you think I’m doing anything with you than you can fucking forget it! I am not having sex with my little brother!” She protested but made no move to get dressed. I wasn’t sure why she just sat there nearly nude. I put my hand on her knee and sat there for a couple of minutes to make sure Oscar was gone so he would not know for sure what I was up to. „What do you mean? I believe he enjoyed it; did you hear the way he was moaning and holding on to my shoulder? He certainly filled my mouth with his delicious load? But, the best part was licking your pussy juice from his cock it was fantastic and I want more of it.” I knew that Oscar was in shock when I sucked him so there was no way really of knowing if he got the slightest emotional enjoyment out of my blow job. I smiled over at Tasha trying to gage her reaction. „I think it is time for you to leave and me to get dressed,” Tasha stammered. She pushed my hand from her knee and struggled to her feet which resulted in my vision being filled by her large sexy ass. I stood up beside her and grabbed both of her hands in mine. „Dear Sister think it is time to go back to your bedroom and have wild passionate sex with your horny little brother. Or, I can send Ryan these pictures of you and Oscar. It is up to you. And, it is also up to you what kind of experience we have. So, what is it going to be?” I ran my hand from the top of her tits down to the junction of her thighs looking her in the eyes. It seemed like hours that we stood there while I wondered if my bluff would work. My sister purred and seductively ran her hand over the large bulge in my pants. I was about to praise her for her wisdom when she used her free hand to reach in my hip pocket and pulled out the cell phone. Stunned I watched her sexy ass run down the hall. She paused and tapped the screen several times. We slowly walked toward each other, „There Ass Hole I deleted the fucking pictures now you cannot blackmail me or Oscar!” I took back the phone and smiled broadly at her. Then I tapped the phone’s screen a few times myself. I turned the phone toward her showing her a picture of her in nothing but her bikini panties and Oscar with his erection showing prominently, „You see Sis I have a app that downloads every picture I take to my computer. So, what have you got to say now?” She was gorgeous standing there with her nipples erect and a wet spot clearly visible on her panties. I was not conceited enough to think that I had made her wet knowing it was likely leftover leakage from her recent activity. Tears began to flow down her cheeks and she, seeing me staring at her chest, crossed her arms over her breasts. Whimpering she pleaded, „I won’t do it! It is so fucking wrong. You are my very sick brother to even try such a thing; there are laws against incest.” Deliberately I closed the gap between us and pushed her arms away from her chest and grabbed a boob in each hand. This caused her to back away until she was pinned against the wall. I ran my thumbs across her nipples and whispered in her ear, „There are two ways this can happen. First, I can take you cruelly right here or secondly you can try to make the best of it and escort me to your bedroom. Either way, Monday afternoons are now mine!” The waterworks began flowing in Ernest as I ran my tongue down her neck. Then I sucked one of her nipples into my mouth causing her entire body to go rigid. After a couple of minutes of this her body suddenly relaxed so I looked her in the eyes as if asking her a question. She sighed, „You bastard I guess if you want nothing more than a body to do things with then I guess I’ll let you but don’t expect anything from me other than the barest minimum. The bedroom is over there.” She had pointed to the guest bedroom but I wasn’t going to argue with her selection as at least she was allowing for things to proceed. I hoped that she would come around and enjoy our tryst. I followed her into the bedroom and watched as she sat on the edge of the bed. Knowing that we only had a couple of hours I quickly undressed. Standing in front of her with my erection in her face I gently stroked her hair and breasts, „You know in high school all the guys kept telling me how smart and utterly sexy you are. It made me sad because I thought I would never find out how sexy you really are. Well, now I’m about to find out. The bare minimum big sister includes giving me a blow job right now.” „You son of a bitch! I hope this pecker falls off!” she snarled as she took it in her hand yanking it in anger as she wrapped her hand around it. At first, she was very tentative barely licking it. But soon she was sucking my cock deep into her mouth bobbing up and down my length. I believe that she was giving such a great blow job not because she enjoyed it but because she wished to get it over with. It did not take long for me to begin moaning and groaning. I was trying to make the ecstasy last but her technique was just too good. „Oh…yes…holy mother…yes…fuck,” I cried out as I filled her mouth with my seed. Load after load seemed to shoot into her mouth like cannon fire. To Tasha’s credit she swallowed every bit of the gooey stuff. She did not stop sucking until I pulled away gasping for air and having a hard time catching my breath. Silently I motioned for her to lay back on the bed but she shook her head negatively. I gave her boob a hard squeeze and looked her in the eyes and reluctantly she gave in. Her hair was tossled around her face, her breasts fell to each side of her chest and the wet spot in her panties seemed to have grown. I bent down and kissed her mouth stabbing my tongue between her lips. She returned the kiss but left her arms limp at her side showing me that she had no intention of letting me think that she liked what was going on. I moved down her body and kissed and licked her feet, „You are so beautiful Tasha, even your feet are sexy! From now on Monday afternoons will not be complete without me helping you cum several times. Now hand over your panties Sis. „Let’s get this over with,” she sighed apparently pissed off but something told me that not all of her was mad at me. She yanked her panties off and tossed them in my face. To my surprise I caught them. The scent was every bit as sexy as I had imagined when I fantasized all those years ago. I tossed them into the pile of my clothes intent on taking them home with me. I resumed kissing her feet while I decided what to do next. I looked up at her wet and matted hairy pussy and the answer was suddenly clear. „Let’s see if little brother can change your opinion,” I cooed as I sucked her big toe one last time. Then slowly I kissed up her leg sucking on her thighs as I travelled up to the junction of her womanhood. A couple of times she started to push her legs together but it didn’t take much effort to get her to part her legs wide. Now her pussy was only a couple of inches from my face so I reached out and caressed her hairy mound teasing her outer lips. „So, fucking beautiful,” I whispered as I let my finger briefly touch her clitoris. Edging forward I finally licked her outer lips slowly and deliberately. Then cupping my hands over her ass cheeks, I ran the tip of my tongue up and down the length of her pussy all the way from her clit to her ass hole several times. The result was my sister’s body shivered involuntarily and a gasp escaped her mouth. I wasn’t sure if I was driving her crazy but I was already crazy with lust myself so I moved in and scooped up cream from her leaking snatch. After capturing a lot of her sweet nectar, I slid my tongue over her nub, making teasing circles around it. Throwing all thoughts of being slow and deliberate to the wind I began wildly flicking my tongue against her clit. My hands moved from her butt so I could wrap them around her thighs pulling her entire pussy flush against my face. My licking consumed her entire pussy still paying attention to her clit which I also took the time to suck between my lips. Soon my sister was thrashing her pussy in my face and her hands were entwined in my hair with growls and moans escaping from her mouth. „You mother fucking son of a bitch,” she growled as she squirted in my mouth. She was gyrating her pelvis wildly as it was clear she was having multiple orgasms. I had never experienced a woman Cumming this wildly before so I continued hoping it would be an experience she would never forget either but then rationalized to myself that this could be normal for her. After what seemed like several more minutes she let go of my hair and her body went limp in exhaustion. I continued for a minute to lick up the honey that was still flowing from her sexy pussy. Reluctantly I broke away from her crotch and slid up her body and gave Tasha a passionate kiss which she eagerly returned before I moved to her breasts and licked, sucked, and kissed them, „You can’t tell me that you didn’t enjoy that can you?” „Shit, it was fantastic but we really can’t be doing this. You really should leave now,” she did not sound convincing especially since she was running her hand through my hair as I nursed on her boobs. I simply smiled up at her knowing she was merely saying what she knew she should say. My erection was back to throbbing and I could not wait any longer so I moved up and kissed her hard with my cock grazing her mound. I adjusted my position so my cock was at her entrance. My sister’s pussy enveloped my cock like a tight fitting silky glove. The walls pulsated against my member as I bottomed out and ground my pelvis against her. Soon we established a rhythm as I slowly pushed in as her hips came up to meet my thrusting. As our bodies came together we would grind together. We had a wonderful rhythm as I struggled to breathe and her fingers clawed my back. The physical tension began to build causing my strokes to get faster and faster. My balls were slapping her crotch I panted, „Oh fuck I’m going to explode…YES!” „Shut the fuck up and give it to me already!” Tasha roared as she grabbed my head and kissed me violently. That was all I needed as my seed shot from my member. I did not stop as I wanted to be very sure Tasha had gotten the maximum orgasms that I could give her. We kept fucking until my cock finally went limp and popped out of her. I rolled off laying on my side beside my sister. I then reached down to her pussy and dipped out our juices and fed them first to her and then to myself. „That was so fucking forbidden and wrong but this felt so great inside of me!” my sister purred as she reached for my limp member and played gently with it. I looked in her eyes once again smiling as my cock tried to get rigid again but to no avail as it wasn’t quite ready for another round. „I didn’t ask you to play with my pecker; I think that Is a lot more than the minimum!” we both laughed as I sucked one of her nipples into my mouth. She rolled on to her side facing me and began to grind her boobs in my face. I took the hint and motor-boated from one to the other. She was still teasing my half-limp member. I glanced over her shoulder and saw the time on the bedside clock meant that her hubby would be home soon but I had to do one more thing. „Sis, your old man will be home in a half an hour but I cannot leave until I’ve explored that terrific ass of yours!” Reluctantly I pulled her hand from my cock and my mouth from those luscious breasts. She did not move so I took matters into my own hands and rolled her on to her stomach. My hands were drawn to her pillowy flesh like a magnet was pulling them there. „I’ve generally don’t find ass stuff that exciting,” she sighed. I started by gently massaging her plump ass. Soon I was kneading her cheeks splitting them apart so I could see her puckering hole. As I did this I crawled between her legs. I ran a single finger up and down her deep crevice and around her rosebud as I bent down and planted butterfly kisses all over the twin pillows. „Shit Sis, your ass is so sexy and your ass hole so beautiful!” I pulled the cheeks far apart and began kissing up and down her crack until I stabbed my tongue inside her tight little hole. At first my tongue met resistance but soon it was wriggling around inside of her bowels. I slid a hand underneath her pussy so that my thumb was rubbing her clit. The sight, aroma, and taste were overwhelming. It quickly became obvious that she was enjoying the action as she was bucking her ass in my face. Her honey was leaking from her vagina as I could feel a shudder run through her sexy body. Knowing that our time for the day had to be almost done I pushed away grabbing her panties as a souvenir and stood beside the bed caressing her ass, „Tasha I guess we had better rinse off in the shower. I’ll take the guest bath and meet you in the living room. I can’t remember ever having such an erotic experience. I think our Monday afternoons are going to be fantastic.” I kept looking back at my sister’s lovely body as I left wishing we would shower together but knew that would only lead to more sexual activity and the likelihood we would be caught by my brother in law. When I got to the door Tasha called out, „We’d better hurry we only have about 10 minutes. Put your towel in the hamper by the tub.” Ten minutes later I greeted my sister with a hug, groping her ass, as we exchanged one last kiss. Then we sat down at the table and started going through the legal papers I brought over. A couple of minutes later Ryan walked in the door. We greeted him like nothing had happened. It took about an hour to go through all the legalese. Tasha walked me to my car which was out of view of their windows. I opened the car door and pulled her to me and cupped her pussy and began massaging it through her clothes, „What time next Monday? Perhaps, we will need to meet more than once a week.” „You’re serious, I thought this one time might be enough to satisfy your curiosity. Any time after12:30,” she sighed with a slight hitch in her breathing. I did not hear the car pull up behind us. We turned to see Brenda our younger Sister walking toward the house. „Now I’ve seen everything, my brother bringing off my sister on the street corner,” She said as she kept walking on by. Tasha and I looked back at each other wondering what Brenda would do about what she saw. My sister reached down and gave my erection a quick squeeze before breaking away and hurrying back to the house.
