Sex With Sister In Law
editor's picks, sister

Hi, everyone. This is my first story in ISS. Although I have been reading iss for 10 years I have never had any story to write till recently. I am not a good story writer nor do I want to satisfy the readers with moaning expressions and last of all please forgive me for the poor language and for the pretty long story. I am a married man with an average body and average 7-inch size penis but I do have a very sexy and dick teasing wife. I have been married for 5 years and prior to that for 7 years when she was my GF from college but this long duration of togetherness had taken a toll on our sexual life. Although my wife still enjoys sex and desires to have sex every single day my passion for sex with the same woman had reduced over the years and our sexual activity had reduced from thrice daily to once a month (yes that is how bad our sexual life has become even though I am a very horny guy) Coming back to the story, the heroine of the story is my sister in law (sil – no names here) who is 11 years younger to me and studying in college. She doesn’t have a sexy body like my wife but she was still good and thinner than my wife. I guess her stats must be 32 24 32.I didn’t have any sexual thoughts or feelings towards her and always treated her like a sister but I guess my demons woke up one fine day. I had gone on a vacation to Agra to see the taj mahal with my wife and her entire family of my in-laws and sister in-laws. When we reached Delhi, we had hired an Innova to take us to Agra and as luck would have it, I was made to sit at the rearmost seat in between my sister in laws. It all started when she wore a lovely one piece dress up to her knees (which she rarely wears thanks to my strict father in law). While sitting, her skirt used to move up to her lovely slim thighs. I decided to make my move on the return journey when it becomes dark. It was very difficult to wait for the entire day to get over and was lustily eyeing her on the tour. Finally, the time had come and I was having second thoughts since I knew my wife would never forgive me and divorce me if I tried any stunts with her young sister but eventually, my demons came out in full force thanks to her exposing off her slim long fair legs. Moreover, she was also tired from the long and tiring journey hence she bent and kept her head on my lap to sleep. When the car left the outskirts of Agra and touched the highway it had become quite dark inside the car and I slowly started to caress her back. She didn’t mind since she thought I was caressing her due to brotherly affection. My hands were sweating even though the AC was very cold and was trembling thanks to the fear of getting caught. As luck would have it the driver was driving roughly and kept braking hard which was making my sister in law to slide and wake up. I knew this was the perfect opportunity for me and I gently put my hands around her waist with my palms touching her flat tummy to support her and make her more comfortable. Little did she know what was coming. Her body tensed and became still as she had never expected this action from me. I slowly whispered in her ear that she can sleep soundly as I was holding her. Hearing my words, comforted her and she quickly fell asleep in no time and luckily for me my other sister in law also fell asleep quickly. I started caressing her flat tummy slowly feeling the outlines of the body. I was very patient and careful in not touching her private parts as I knew she will wake up and object and my fun session would be over. After some time, I inserted my forefinger into her naval hole and she twitched. She somehow realized what I was up to and didn’t object with my Actions which gave me the courage to proceed. I slowly moved my hands to her slim, fair, soft and long legs and again her body twitched even more and her breathing became harder. I knew she was liking it and I started to caress her legs from the knees till her thighs (didn’t want to touch her private part immediately as I wanted her to become extremely horny) and back to her knees. After repeating this action for a few more times, I slowly started moving the direction of my palms inside her thighs till the edge of her pussy and back to her thighs. While approaching her pussy, I could hear a very slight audible moan from her then I knew she was slowly becoming mine and was thrilled. With every stroke, I kept inching towards her pussy and every time I approached her pussy she would tighten her thighs to prevent me from touching her pussy(don’t know why females do this). I knew I had to break her final resistance and with my other free hand, I started caressing her tummy and naval. With both my hands working simultaneously I could feel the desired effect as her resistance kept decreasing with every action. Finally, I moved one of my hand slowly towards her pointed and supple breasts and gently squeezed one of her breasts. I guess this was too much for her and she gasped at the same time splitting her thighs. This was what I was waiting for and quickly moved my fingers to her pussy which was followed by another gasp. Once I started massaging her pussy and squeezing her breasts she completely surrendered to me and the road for pleasure was clear as I knew I had her in firmly in my control. After 10 minutes of vigorous rubbing, her pussy started to lubricate like a river. Her moans were getting louder but thankfully the vehicle was making a lot of noise so no one got up and no knew what was happening. I then slowly put one finger inside her pussy which was tight and just enough for one of my finger. I started thrusting my finger inside, moving deeper and deeper. After 10 minutes, I could feel her body getting tensed and understood she is going to get an orgasm and had to cover her mouth with my other hand to prevent her from screaming loudly. After getting her orgasm, she was pushing my hands away but I continued to thrust my finger inside with great speed bringing her to her second and third orgasm within minutes. My mother in law got up and she immediately pushed my hands away and we were reaching Delhi too so she adjusted her dress. Once we reached our hotel I was convincing my wife to make her sleep with us for me to fuck her and she agreed innocently not knowing my intentions. She came to our room very reluctantly and slept next to my wife. I was finding it very difficult to sleep and waited patiently for 2 hours for my wife to fall asleep. This was the longest wait in my history. Once I was sure my wife was in deep sleep by gently nudging her, I got up and went to sil side and started touching her thighs and slowly moved my hands over the dress to her hips. I could make out she was not wearing any panty. I moved my hands slowly to her breasts and found out she was not wearing a bra too and her nipples were erect and hard like a stone. Maybe she was expecting this. I started squeezing her breasts softly and massaged her clits over the dress slowly with my other hand to get her into heat. This time she responded quickly without any resistance and split her legs completely and started twitching her body from side to side. She was fully awake and kept looking at my wife fearfully. The thought of fucking her in front of my sleeping wife also added to my pleasure. I was determined to Have sex with her and put my hands on her pants and quickly went to her pussy and started massaging her clitoris and started moaning loudly again. I then removed her pants and shirt and admired her slim model like body. Undressing her slowly was also very erotic for me. She became shy and tried to cover her pussy but I pushed them away and saw there was not much hair and was trimmed nicely. I wasted no time and removed my dress quickly and slowly licked her toe and my tongue started its journey from toe to her pussy. I stopped licking just when my tongue was about to reach her pussy and repeated the same process with the other leg. I wanted her to beg me to fuck her and I could see she was getting frustrated and wanted me to suck her pussy. From her thighs, I moved my tongue to her naval without touching her pussy and put my tongue inside her small naval hole. Then my tongue continued its journey to the outer curves of her pointed breast and on to her tits but I purposely didn’t lick or suck her nipple and could see her frustration building up. I wanted her to beg and plead with me for my tongue. Then my tongue continued to her neck and then to her ear and I gently sucked her ear lobe and the back of her ear. It is very erotic for me to hear females moan. Just hearing any female moan makes my penis rock hard. My SIL was moaning loudly continuously and I was so horny that at that point of time I didn’t care if my wife woke up. From the ear, my tongue went to her outer lips and started kissing her and sucking her lips. I then parted her lips and put my tongue inside her mouth and immediately started sucking her tongue and drinking all her saliva. We kissed passionately for 10 minutes and then she finally whispered in my ear to suck her nipples and bite them and also suck her pussy. I obliged and went to her erect and hard nipples and sucked her nipples hard and at the same time squeezed both the breasts very hard like squeezing out the water from a sponge. I sucked and squeezed her breasts for 10 minutes and then my tongue slowly went to her pussy. My tongue played with her pubic hair and then went to the top of the pussy cut (don’t know the word for this)and dipped my tongue into the cut and split her pussy with my tongue and started moving slowly down the cut to her pussy hole and back to the top. Her pussy was emanating a strange odour which was neither disgusting nor pleasant but it was making me wild and horny. I could see my wife moving and kept my hand in her mouth to shut her up. I gently sucked her clitoris and started biting and pulling the clitoris gently with my teeth. After playing with her clitoris with my tongue for 10 minutes I started sucking her left labium and then her right labium alternatively. Then my tongue moved to her pussy hole but it was too small for my tongue so was just lapping up all her juices secreted for another 10 minutes. Then my tongue slowly moved downwards to her ass hole and this was too much for her I guess as she jumped and insisted forcefully that I do not waste any more time and to insert my rock hard penis in her pussy and asshole. I was telling her to wait for the ass licking but she wouldn’t listen and was pulling my body over hers. I decided to oblige and positioned the head of my penis at the entrance of her pussy and gently pushed inside. It was struggling to go inside as it was tight and started using force. I could see that it was paining for her but she was urging me to go on. Finally I lost patience and decided to give one big push and finally my entire penis went completely inside. She started to cry because of the pain and I gently kissed her and waited for 5 minutes for her pussy to get used to my penis and for the pain to subside. Once I got the green signal to continue I started pumping her and then increased my speed and started ramming her pussy. Within no time she got her first orgasm followed by her second and third. I continued pumping for hard for 10 minutes And started to feel the ecstasy building up inside me and within no time I pumped a tremendous amount of sperms inside her pussy. I continued to lie on top of her for 10 minutes and could feel my sperms flowing out of her vagina. The smell of her juice and my sperms was very erotic and I was savouring the fragrance. After 10 minutes, I wanted more and made her suck my penis. She was disgusted but I threatened her I will wake her sis and she put my limp penis inside her mouth slowly. The feeling of my limp penis becoming hard inside her mouth cannot be expressed. I guess she started to enjoy sucking my penis. After 5 minutes of sucking got her into the doggy position and positioned my penis on her asshole. I put a lot of her pussy juice on my penis and pushed my penis inside her asshole with great force and it went completely in. I waited for 5 minutes for the pain to subside and started to pump. She started to enjoy the pumping the was urging me to pump harder and harder till I ejaculated inside her asshole with ecstasy. We cleaned up and had a great sleep. The next day I called her alone and apologized for my behaviour but was shocked to hear that she wanted us to continue having sex. I gently declined and reminded her that she is my little sil and this must be forgotten. I also gave her a pill and luckily for me she didn’t become pregnant. Luckily she has understood but now and then she gives me hint for sex whenever she is horny or whenever we are alone in the house. My next sex session was with my other sil which I will publish in my second story. I don’t know if she has found out as both my sils are very close to each other and share everything. In the meanwhile, feedbacks are always welcome from any ladies and I can be reached at [email protected]
