She wasn’t much to luck at but she had a fantastic sense of humour and a great pair of tits. They were at least a D cup. We hadn’t really become that close even though I had been married to her sister, Karen for about 18 months. We exchanged pleasantries; had a little joke with each other every now and again, but never became really close. One day I had finished work early. My wife, Karen was at work till late and Tina’s husband was also at work. I decided to walk up to Tina’s house for a chat and a coffee as I was at a loose end, and anyway I couldn’t stop thinking about those fantastic tits. Her kids would still be at school so there would be no interruptions. I approached her house; her car was parked in the drive so I knew she was in. She never goes anywhere without her car. I knocked on the door and waited for her to answer. I knocked again but still no answer. I peered through the kitchen window and saw her coat hung up and the coat hanger. I went back to the door and tried the handle. The door opened and I walked in. I walked into the kitchen and into the living room but didn’t see her. I heard noises coming from upstairs, like furniture moving. I thought she must have been cleaning so I slowly walked up stairs. As I reached the top of the stairs I heard a soft groaning noise coming from her bedroom. I gently and slowly walked to the bedroom door. The door was slightly open. I looked through the gap in the door and saw Tina’s reflection in the dresser mirror. There she was naked, back arched, head tilted back. I moved back away from the door excited and curious. Her husband was at work so who was the lucky person underneath her. I went back to the door and peered again through the gap. This time she was on all fours being fucked doggy style. I pushed my head in further to see if I could get a glimpse of her new lover. My cock was straining against my pants; I was so turned on watching Tina getting fucked by………her stepson! Tina was 31; her stepson had just turned 18. Gary, her husband had been married before and brought his son to live with Tina and himself when they got married 10 years ago. Now, near enough after his 18th birthday he was fucking his step mom. She was loving it. Her eyes screwed closed and panting like a thirsty dog. Her tits swung back and forth as her stepson fucked her from behind. I went back down stairs through the door and home. Back home I headed straight to the bathroom to jerk off, thinking of Tina’s fantastic tits swinging back and forth. For weeks I jacked off thinking of Tina being unfaithful with her stepson, till I decided I was going to have some fun with her myself. I volunteered one morning to help her grocery shopping. I needed stuff from the shops as well so I suggested I hitched along with her for company. We did the shopping and went back to her house to unpack. I carried all the groceries in from the car into her kitchen. Tina unpacked the bags and put the groceries away. She was wearing a short black skirt; a white blouse and black high-heeled shoes. Her long blonde hair was tied in a bob at the back of her head. She opened the refrigerator door to put the dairy products away. It must have been cold when she opened the refrigerator door because as she closed it and turned round her nipples had started to poke through her bra and blouse. “You cold Tina?” I jokingly asked. “Why would I be?” she sternly replied. “Just asking.” I answered. “I called up her a few weeks ago but couldn’t find you. Your car was parked outside but no answer at the door.” “What day was that?” she asked. “Tuesday morning. I had finished work early and thought I’d have a walk up.” I replied. “Erm, Tuesday. Yes Tuesday I popped out to the post office. You must have missed me. Lots to do, People to see.” She nervously replied. “Don’t you mean PEOPLE to do, Lots to see?” I counted. “When I came up here that Tuesday I tried the door. To my surprise it was open. I heard noises coming from upstairs so I went to investigate. You must be mistaken Tina. You were in and so was Brandon, your stepson.” “YOU BASTARD!” She shouted. “Wait till I tell Karen and Gary about this.” “You won’t tell them Tina will you. You don’t really want your whole family knowing you are fucking your stepson do you?” I answered. Tina went very quiet, dropped to the floor and started crying. I knelt down beside her. “Don’t worry Hun. I wont tell anyone. It will be our little secret ok?” I said trying to comfort her. I moved my face to her neck and softly kissed her. I moved my hand to her to her shoulder and pulled the blouse from her skin. My lips kissing her neck and shoulders. “No Way” she shouted. “Not a chance in hell are you going to do that to Me.” “Tina, the way I see it is you don’t have an option” I smiled. I pushed her to the floor and pulled apart her Blouse. Tina began crying more and more. Her tits bounced in the bra as she juddered. I pulled her up against me and unfastened the bra. Her breasts were so soft and firm. She lay down slowly as my mouth went to her nipples. My mouth slowly kissing and licking one, while my hand gently caressing the other breast. Tina’s sobbing slowly turned into heavy breathing. “Please stop Neil. PLEASE. Anything but this.” She begged. “It’s either this or D.I.V.O.R.C.E. hun” I replied. My mouth and tongue swapped from nipple to nipple. My hand slipped down her side and unfastened her skirt. I slid down her body and pulled off her skirt, leaving her lying there in only her panties. She moved her hands to cover her breasts. “Now now, you can make this easy or hard. It’s up to you.” I told her and my hand slipped into her panties. “Not on the floor then. Let's go to the bedroom. Please not here.” She sobbed. We both stood up and headed upstairs. Tina slowly walked into her bedroom and sat on the bed crying. “Take the rest of your clothes off and lay back” I ordered. Tina slowly removed the rest of her clothing. She slipped out of her skirt and threw that to the floor. “I said ALL of your clothes,” Very slowly, Tina removed her panties and bra and gently dropped them to the floor. She looked so sexy. Her breasts rose and fell as she started to breath deeply with nervous anticipation. I removed the rest of my clothes and climbed onto the bed. I run my tongue along her legs, up her thighs, across her pussy and around her stomach, finally resting onto her nipples. I began slowly sucking those large nipples of hers, occasionally biting them to provoke a response from Tina. My fingers ran up and down her thighs and around her shaved pussy, gently rubbing up and down her pussy lips. Within minutes of my fingers probing her pussy I could feel her getting wet and her nipples getting hard. I looked up to her face. Her head was slightly tilted back and her eyes were closed. The expression on her face wasn’t that of worry now but of pleasure. I slid down the bed and buried my face between her thighs. She gave some resistance but not much. I replaced my fingers with my mouth and tongue, licking and sucking her pussy lips and her slowly hardening clit. Her legs began to part on their own free will as I ate her pussy. My tongue, gliding up and down her pussy lips, over her clit produced gasps of air from Tina. I looked up from her pussy to see her tweaking her nipples. I quickly slid two fingers deep and hard into her pussy. Tina let out a small cry, and carried on playing with her nipples. I slid my fingers in and out faster and faster, fucking her with them. Her hips moved in time to my fingers as she quickly started gasping for breath. “Faster, faster” She whispered as I furiously fucked her with my fingers. “Yes, yes, yes, yes!!!!” she replied as I honored her wishes, my fingers covered in her juices, feeling nice and safe and warm deep inside her. She let out a loud gasp as she came over my fingers. I removed my fingers and licked the juice from them. I took hold of her and turned her onto all four. Bringing her hips towards me I drove my cock deep into her pussy. She gasped for air as I brought her hips fully onto my cock. Tina arched her back as my cock slid in and out of her wet pussy. I looked again into the bedroom mirror to see her eyes tightly closed and her tits swinging back and forth. “Fuck me harder you Bastard” She cried. I increased my tempo in reply. “Yes, Yes, YES” I thrust my hips to meet hers as I felt myself tingle and about to cum inside her pussy. I slowed myself to make sure every drop was entered into her. She slouched onto the bed as I released my cock from her wet pussy. Her hands slid down the bed and she started to finger herself to her second climax. I turned her over onto her back and brought her head up, forcing my cock into her mouth. She gagged a little but began to suck me hard again. My ass felt a little jolt as she sneakily forced her finger into my ass. “Neil likes it when I do that” She laughed. “Well what’s good for the goose?” I replied as I turned her back onto all 4s and slowly pushed my cock into her ass. “NO, No not there” She begged. It was too late. My cock was in her ass fully, slowly sliding in and out of her. Her protests suddenly turned to submission as my cock pleasured her ass. Slowly I pushed my cock in and out of her ass. Little gasps for air from Tina encouraged me as I sensed she was enjoying it. I could feel myself about to cum a 2nd time but I didn’t want to cum in her ass. I pulled out of her ass, crawled up the bed and lay on my back. Taking hold of the back of her head I brought her down onto my cock. She opened her mouth and took in my cock. Her head bobbed up and down, faster and faster as I started to gasp for air. I took hold of her head again as I came hard into her mouth. She gagged and coughed a little but swallowed and licked the cum away from her mouth. I closed my eyes and let go of her head. She collapsed beside me licking her lips. I looked over to her and gave a cheeky wink. I stood up and got dressed. “I hope I don’t catch you again young lady,” I warned. “I do,” She said with a smile. Blackmailing Sister in Law Ch. 02 3 months had passed since the punishment (if you could call it punishment) of my sister. I caught her one-day having wild, mad, passionate sex with her stepson while her hubby was at work. With me being an upstanding gentleman I had to show her the error of her ways, so punished her with all my strength. I’m pretty sure she enjoyed it too. Well, as I had mentioned it had been 3 months since the punishment of sissy and life was going pretty well. We hadn’t spoken to each other much but there didn’t seem to be any friction between us when were in the same room. One night while I was screwing my wife’s brains out she mentioned something that shocked and excited me. “Neil hun, would you like to see me with another woman. Would you like to watch me licking and sucking another woman’s pussy?” Karen asked. I gagged and gasped for air. “If you want, and iv thought a lot about this. Set me up with a friend of yours, or mine and I am sure we can add a little spice to our relationship” she whispered. “You meant it,” I asked. “You want me to arrange for a threesome with another woman so I can watch you play and lick her pussy.” “Sure. I’m willing if you are” she grinned. ****** I let what Karen had said to me ride for a few days incase she was just trying to keep me going in bed, but she still seemed keen for what she had proposed, to happen. It didn’t take me long to conjure a perverted and highly sexual scenario in my mind. I went along to Tina’s house when I knew her husband wasn’t home. Tina, for those who didn’t read the 1st story is my cheating sister. I told her if she didn’t do as I asked that I would spill the beans on her little affair with her stepson. With little persuasion she agreed to my little plan. I was to bring along a female friend of mine to help punish Tina for being such a slut. Tina was to be gagged and tied to the bed so my guest and myself could pleasure her and ourselves. The night had arrived, Tina had been prepared for my pleasure and was lying on her bed tied, blindfold, gagged and naked. Karen and myself had got into the car ready to drive off to Karen’s surprise. “Put this blindfold on hun. I want the experience to start from here. Ill let you take it off only when the night is over.” I smiled. She agreed to be blindfold, so we set off to meet her naughty sister. As we pulled up outside of Tina’s house, I opened the car door and guided Karen up through the house and into Tina’s bedroom. Tina lay there naked as the day she was born. Her breasts heaving up and down with sexual anticipation. I took hold of Karen’s hand and guided her to the bed where her sister lay. “There is only 1 rule. Blindfolds stay on,” I commanded as Karen slowly dropped to her knees and searched out her sister’s naked body. I sat in the corner on the dresser stool and watched as Karen’s hands slid up her unsuspecting sister’s legs. Both sisters not knowing whom the other woman was. As Karen climbed onto the bed her hands slid up Tina’s thigh. Tina let out a quiet groan as Karen’s hand stopped around her thigh. Karen’s lips replaced her fingers. She kissed and licked Tina’s soft skin. She knelt up and unbuttoned her blouse and threw it to the bedroom floor. Her hands reached around her back and unfastened her bra. Her tits, not as big as Tina’s fell out of her bra. Karen’s hands probed Tina’s thighs and found her pussy. She lent forward and put her lips onto Tina’s shaved pussy. She gently licked her sister’s pussy till soft groans came from Tina’s mouth. I dropped a hand to my side and raised a small camcorder, putting it to my face I pointed at the 2 unknowing sister and pressed the record button. Karen slowly licked and sucked her sister’s pussy, both letting out groans of pleasure. Tina played with her stiffening nipples and she was being eaten out by her sister. I unfastened my jeans to ease the pressure of my hardening cock. Karen climbed up the bed licking Tina’s tingling body as she searched out her face. The lips met and both frantically kissed and licked each other’s face. Tina’s hand slid down the side of her body and to Karen’s thighs. Karen parted her thighs allowing Tina access to her wet pussy. I stroked my hard cock as I recorded the sisters. Tina slowly finger fucked Karen as Karen sucked on Tina’s nipples. Biting them a little harder each time the excitement built in her pussy. Karen slid further up the bed and gently sat on Tina’s chest. Her hands searched out her sister’s head and brought it forward to meet her pussy. Karen inched a little forward as her sister licked and sucked her pussy. Karen arched back and excited her own nipples as Tina ate her out. I got up from my seat, placed the camcorder on the dressed pointing at them and walked over to the bed. Beside the bed was a large thick vibrator. I picked it up and placed it into Tina’s hand. I sat back in my seat and picked up the camera again. Tina smiled and Karen gasped as she slowly rubbed the vibrator along Karen’s pussy. Her body moving forward, trying to get more of the vibrator. My cock was about to explode as I watched the sisters fucking each other. I put down the camera again and walked over to the bed. While Tina was fucking her sister with the vibrator I guided my cock into Tina’s mouth. She refused at first but a little coaxing she let it in. I pushed her head further onto it and she quickly sucked my cock. It didn’t take long for me to cum in her mouth and like the slut she was, drank every drop without struggle. I took hold of the vibrator and pushed it further into Karen’s begging pussy. She let out a loud gasp as the vibrator slide along her hard clit. Tina sucked the last of the cum from my cock and I handed her back the dildo. Karen began to bounce and pant as she was approaching orgasm. Tina fucked her harder and harder with the dildo as she felt her sister about to erupt. Karen screamed out as a shattering orgasm shot through her body. Tina pulled out the vibrator and was met by a wave of juice as Karen came on her sister’s face. Tina licked the juices from her face as Karen slid down her body and kissed and licked her lips. Karen slid further down to Tina’s pussy, took hold of the vibrator and ran it up and down her sister’s pussy lips. Karen began to tease Tina with the dildo. With each touch of it her lips sucked my cock harder. I pulled my cock slowly from Tina’s mouth and stood next to the bed. I reached over and pulled away Tina’s blindfold. She had her eyes closed at first but opened them and looked up at me. She gasped as her sister, slid the dildo in and out of her wet pussy. She looked down at the strange woman that was fucking her pussy so professionally and let out another gasp as she saw it was her own sister, blindfold sliding the dildo in and out of her pussy. Tina looked up and me and scowled. Her head shook from side to side saying no, NO. Tina was shocked to see her own sister fucking her. She mouthed the words… “Please no, no” as the thought of her own sister fucking her pussy repulsed her. I knelt down by the side of Tina. “You WILL enjoy yourself sweetheart. It would break Karen’s heart to know what you two have been up to. Not to forget all the family disgrace if the video got out in public,” I whispered. “What video?” She asked quietly. I pointed over to the camcorder placed on the side recording every erotic moment. Tina froze then screwed up her eyes, let out a gasp as an orgasm run through her body. Karen slid the dildo out from Tina’s pussy and licked the juice from it. “I have another little surprise for you lovely ladies” I announced. I dashed downstairs and out to the car. Picked my bag from out of the boot and ran back upstairs to find Karen loving licking her sister’s pussy. “Now sweetheart, let me put this on you”. I took hold of Tina’s hand and helped her off the bed. I pulled out a large black strap on from the bag and started to put it onto Tina. Tina pulled away; I took hold of her arm and pointed to the camera. She stopped pulling away and let me put the strap on here. “Now Hun, something special” I whispered into Karen’s ear. I helped Karen onto all 4s and brought Tina behind her. I guided the strap on into Karen’s pussy. She gasped and cried out as the long, black dildo slid into her. I took hold of Karen’s hips from behind Tina and pushed my hips into her, which in turn pushed the strap on, Tina was wearing deep, into her sister. Tina’s eyes began to fill with tears as she slowly fucked her sister. Taking hold of her hips and rocking back and forth. I gently pushed them both onto the bed. Tina still fucking Karen, I took hold of Tina’s hips and slid my own hard cock into her pussy. Weather she wanted to or not Tina was going to fuck her sister hard. I took hold of Tina’s hips and slid my cock in and out of her beautiful pussy. Tina in turn, fucking her sister. I quickened my pace as I felt my balls about to erupt into Tina. Karen had taken hold of Tina’s hips and was pulling her deep into her pussy. Karen cried out as she had another orgasm. I pulled out my cock, cum shot onto Tina’s ass and back. Both girls gasped for breath. Karen took hold of her sister’s head and kissed her passionately. Tina didn’t react at first but slowly responded to her sister’s kiss. Tina’s tongue slid into Karen’s mouth then kissed her face. I unfastened the strap on and took it from Tina. Tina got off the bed as I took hold of Karen, her blindfold still in place and fastened the strap onto her. I took hold Of Karen’s hand and helped her off the bed. I motioned for Tina to get back onto the bad, on her back. I helped Karen back onto the bad and guided the dildo into Tina’s waiting pussy. Karen didn’t need any prompting; she slowly began to rock back and forth, fucking Tina’s wet pussy. As a few strokes went on, Tina took hold of her sister’s hips and helped her by pulling her hips deep into her. Karen leant over and kissed her sister’s mouth. As she bent over I stepped up and gently guided my cock into Karen’s ass. She screamed as my cock slid into her tight hole. I fucked Karen’s ass as she fucked her sister’s pussy. Tina’s tits looked fantastic as they rocked back and forth along with Karen’s motion. I felt Karen tense up an orgasm shot through her body. Her head instinctively dropped to meet Tina’s and kissed her passionately. I pulled out of Karen and watched as she fucked Tina faster and faster. The look on Tina’s face had turned from horror to pleasure as she felt herself about to climax. She was pulling Karen harder and faster into her. She gasped as the orgasm ran through her body and in return, kissed Karen passionately on the lips. I took the strap on from around Karen’s waist and guided her off the bed. “I hope my dear you have enjoyed yourself today. I know I have. I whispered. Tina lay on the bed looking at both her sister and me. Not in disgust but in pleasure. It did shock her at first but she came round to the idea. I had also taped the performance of the 2 sisters just incase I had need for it. Karen never knew about her sister. I may tell her. I may not. We shall have to wait and see…
