Seduced By My 20 Y/o Sister In Law

I have been happily married for 6years. I have a great sex and personal life with her. I am close with my wife's family, and agreed when my sister in law was going to move in while going to school. I have known my sister in law, let's scale her "Amy", for 7 years. She was like the kid sister I never had. Amy was what you would think a good girl is. She is very quiet and shy, doesn't have many friends. She is very pretty, tall, and has been blessed with all the female attributes that drive boys crazy. I never pay attention to how attractive was, l saw my kid sis. I work in the medical field, and my wife has her own business, so we are rarely home during the day. And we knew her well, she wasn't the type to have boys over, or even have a boyfriend. My wife, wanted her to get laid, maybe that would open her up.

I saw and heard something, I wished I never did. And now, has made my happy life, extremely stressed, both good and bad. I have to go back 2 weeks before what happen, to give you a full understanding. My wife and I, have been working so much, we haven't been able to be romantic as we were so use to. So we left the kids with Amy, and went out to dinner and dancing. My wife was a latin dancer when we met. When we danced, I would be fully aroused. We danced and drank heavily. We had to go home because if we didn't I would have fucked my wife at the club. I forgot how much of a turn on it was dancing with her. We got home and the kids were asleep, Amy was on the couch in a pair of boxers and tight tank top. That was the first time I noticed her tits, and how perfectly perky they were. My wife and I were so drunk, but not too wasted, that we didn't realize her areola and nipple were showing. We were making out in the taxi. Amy pointed it out to her, and my wife staggered to our room saying, "give me 5 mins and come take me." Amy was looking at me in a way that she never did before. We have been drunk in front of her before, so that wasn't it.' I asked what was wrong, she shook her head, as if she was just day dreaming, and said, "nothing a looked away. I heard my wife called and I was egger to please her. I realize as I started walking, my pants were undone and my dick was sticking out of the slit of my boxer.

When I enter in our room and being in the shape I was, I left the door wide open. My wife had her back to me as I reached up her dress and slide her panties off. She was wet already, rubbing herself. She always does before sex, I have a lot of girth and it hurts if she is not wet and relax. I bent her over, and licked her dripping labia from behind. I thru her on the bed and finished preforming oral on her as she cried out my name. She love to talk dirty, and demand that I make her cum in my mouth. When she did, I traded places with her. While my wife, who give the best fellatio, started licking the rim of my head. I am amazed and love the way she is able to fit me deep into her mouth. I came into her and cuddle. My wife woke me up about an hour later riding my, cock which was already hard. She was so loud and if Amy was a wake she definitely heard. We finished went back to bed. In the morning we apologized for the loud noise, but Amy said she was asleep and didn't hear. Good, the things her sister says, shouldn't be heard.

Now back to the present, I came home around 11:00 am to grab my phone that I forgot that morning. I had to hurry and started rush out. I heard and moaning and yelling, the kind you do when having sex. I thought Amy had met someone and took her sisters advice. I was curious and aroused, so I walked down the hall. I notice it was from my room, I thought man why didn't she take him to her room. The door wasn't shut and from the crack by the hinges I could see my bed. I saw Amy rubbing herself with one hand and using a sex toy with the other. I admire her body and perfect skin. I found myself wondering how nice it would be to taste her, or suck on her perfectly firm breast. I caught myself and decide I should go. I heard her talking dirty as I walked away. I quickly went back when she said my name. She was playing that night we came home drunk over and saying what she wished she said. "Is there something wrong? How about you come over here and take that thick cock, and treat me like I was Marcy". Marcy is my wires name. I had to leave, if I didn't it would end up bad.

Since then, I haven't been able to stop think about her. I fantasize about her, while fucking my wife. She even commented on how the sex has been amazing. I have never been attracted to younger girls, this was a first. The problem I have now, is I am off Monday and my wife wants me to take Amy out. She wants me to show her a good time, because she doesn't get out. I just kept think if I did show her a good time, my life would be ruined. That Monday, I wanted to get up late and go to only public places. I was hoping to come home and Marcy was already there. I woke up later then I wanted. Amy was shaking me, saying "come on are you going to show me a good time?" She said it in such a seductive way. I thought maybe it's just in my head. I jumped in the shower, thinking she had gone to the kitchen for breakfast. I quickly showered and wrapped the towel around my waist. I went to the closet to get my close, and I notice Amy sitting on my bed. That was not the problem, she was wearing Marcy's sexy skirt. It is an old skirt she had, that was too short and we used it while role playing. It stopped right below her labia. I froze, and try to talk, but I just mumbled. She said that, she has been fantasize about since that night we came home and my dick was hanging out. I finally was able to speak and said, Amy what's got into you?" She was really close to me, I felt her finger tips at my waist where the towel was. I could feel my dick rise as she made a little s pattern there. "You are my wires sister.", was all that came out. She whispered into my ear, "then treat me like her." I wished I could sit here and tell you I came to my senses. I got dressed, left and nothing happened.

The truth is, I became the aggressor, I thru her on the bed, wrapped her long legs around my head and swallowed her cum. I was the one who took her virginity. I didn't stop when I push my dick into her. It hurt me as much as it did her. I just kept pumping her as she yelled in my ear, in pain, saying don't stop. I didn't even when I could feel the sperm rushing for my testicles. I fill her with it, saying I am glad you initiated it. I didn't even think about my wife and kids, laying there in bed after sex. All that was going thru my mind was, I can't wait until my dick gets hard again. We had sex another time and the result was the same. My wife came home to find Amy int the kitchen, happy eating cereal. She asked her if she had a good time, and Amy said the best, it is exactly what I needed. We already had a story made up, with great detail. My wife came to me in the back yard and gave me a kiss. She was so happy to see her sister pin such a good mood. As she walked back in, she said " Tonight I will wear my mini for you." It 's been 2 weeks since that day, and instead of stopping, we meet up in the study room of her college, or the library and once in an adult theater. She is like a drug that I can't quit. I need to end it, but how?
