Introduction:

When my wife learned that my sister aroused me she agreed to help me seduce her.

When I saw my seventeen year old sister after being away for five years I was astonished by her loveliness. I was sixteen years old when she was born. Two years later I left for college. At the university I received an undergraduate degree, a master’s degree, a PhD, and eventually a teaching position. Somehow I had continued to think of my sister as a little girl. She was not little anymore.

The incest taboo is an instinct that usually develops when one grows up with those whom it places beyond the range of sexual desire. I felt enough of that instinct to feel guilty about desiring my teenage sister, but not enough to avoid desiring her.

My seventeen year old sister had the face of a beautiful child, and the shapely body of a young woman. In spite of my best efforts, I could not help but admire her large and firm breasts, her slender waist, and her rounded hips. When my sister noticed my admiration and sensed my desire she looked down, smiling shyly, and blushing a bit. Modesty in one so beautiful arouses me.

My wife and I were visiting my parents and sister for Christmas. For various reasons I had not been back for five years. I would have thought that my sister was one of the most popular girls in school. The second day I was back my mother mentioned in passing that she had not even been on a date yet. The thought that my beautiful sister was not only still a virgin, but had never been kissed aroused in me even more desire, and more guilt, but not enough guilt.

My wife, my parents and I went to a New Year’s Eve party together. After the party and too many drinks my wife and I lay in bed talking. Pliny the Elder wrote, “In vino veritas,” which in English means, “In wine there is truth.” Alcohol can work as a truth serum. My intoxicated state enabled me to discuss my feelings about my sister with my wife.

“After we got married it became clear that my sex drive was stronger than yours,” I began.

“That’s right, and I gave you permission to find a mistress. I even talked about introducing you to a single friend of mine, but you did not seem interested.”

“I have found someone I am interested in.”

“She’s your sister, isn’t she?”

“Is it that obvious?”

“To your loving wife of six years it is. I don’t think your parents suspect anything. Your sister may.”

“Are you disgusted with me?”

“Not unless you use coercion to have your way with her. I know you well enough to know you would never do that.”

“Of course I wouldn’t. Incest can be damaging to a girl. I love my sister. I do not want to do anything that would harm her in any way. Right now this is only a fantasy. I am glad I can talk to you about it. You must never tell anyone about this conversation.”

“I won’t,” my wife said. “I am complicit. I am sort of bisexual myself. You are the only man I have been with. I have never been with a woman. Nevertheless, I find that I desire your sister too. Right now we should only talk about this. We need to proceed cautiously. We must be patient and sensitive to your sister’s desires. I remember how I felt when I was your sister’s age. I had never been kissed. I wanted to be kissed, but only by the right boy. I was not in a hurry to have sex with someone, but I knew how wonderful love making could be.”

My wife continued, “Your sister may be thinking about this too. I have seen her looking at you when you did not know about it. I want to help you seduce your sister, but we must be sure that she enjoys every moment of her seduction. We must not pressure her in any way. We need to be sensitive to her desires. If she does not want it we must stop before she realizes what we are trying to do. If it happens it must seem to happen naturally.

“Our seduction of your sister should be something we position ourselves to allow to happen. If your sister desires you, and I think she does, she should be made to think that she is seducing you.”

“We live six hundred miles away. This will be difficult,” I said.

“Invite her to spend Easter vacation with us,” my wife suggested. “Do not do anything sexually evocative unless she takes the initiative.”

“That is the best we can do,” I admitted, “but I do not want some boy in school to be in first.”

“He won’t be. Your sister wants her first time to be perfect. I will help you achieve that.”

“Yours is a good idea,” I told my wife. “Even if nothing sexual develops I want to create a bond with the sister I neglected while she was growing up. There were probably times while she was growing up that she needed a big brother. I was away at school doing things I wrongly thought were more important.”

“Your sister does not seem angry at you. I can tell that she loves you.”

“I love my sister, and you.”

My wife kissed me, slipped out of her nightgown, and said, “Pretend I’m your sister.” She made love to me passionately. Thinking about my sister increased her libido, and mine.

A month before Easter I called my family. My mother answered the phone. My sister was visiting a friend she told me. When I suggested inviting my sister to spend Easter with my wife and me, my mother thought it would be an excellent idea. Several hours later, when I talked to my sister she was delighted with the idea.

When we picked up my sister at the airport for Easter my wife hugged her, saying, “You look gorgeous, Darling.”

I said, “You look even more beautiful than last Christmas.” My sister was not used to compliments, however sincere. She blushed, giggled, hugged me, kissed me on the cheek, and said, “Thanks.”

Then she said, “I’ve been accepted by your university. I wanted to be the first to tell you.”

“We are so happy,” my wife said, “But we knew you would be accepted. You can live with us.”

We spent the four days of my sister’s visit showing her the sights of the nearby city, attending Easter services at a cathedral, and visiting the university where I taught. I told her I could probably get her a paid internship at the university for the summer.

“Gosh, thanks that would be great,” my sister said.

When my sister noticed the hot tub in my home my wife suggested she bring a bathing suit for her summer stay. “But not too much,” I teased.

“Oh, stop that,” my sister said giggling. “You’re my brother.”

On the last night before my sister’s flight home the three of us watched television. My wife and I were sitting on a sofa. My sister was sitting in an easy chair. My wife was snuggling next to me wearing nothing but a bathrobe. After about an hour she surprised me by removing her bathrobe, and sitting next to me completely naked. I was afraid my sister would be offended by such an obvious display of marital lust. She was embarrassed, but looked enviously at my wife.

Our house is built so that the guest room where my sister was staying is across the hall from our marital bedroom. My wife left the door to our bedroom open so that my sister could hear us make love that evening. When I got up during the night I was pleased to see that my sister had left the door to the guest room open too.

The next morning my sister walked naked to the bathroom to take a shower. She did not look at me, only at the ground. When I looked at my wife, the look of caution on her face told me that I should not try to do anything. I put on a bathrobe over my pajamas to hide my erection.

The next day when my sister was about to get on her plane, my wife hugged her, kissed her on the lips, and said, “We’re looking forward to this summer.”

My sister looked flustered before saying, “Me too.” Then she turned around and left, after waving at us.

When my wife and I got home we had several glasses of wine. “Well, what do you think?” I asked my wife.

“I think we might have been able to do it this visit,” my wife said. “I would rather your sister spend the rest of the school year looking forward to this summer, and wishing that we had. These things take time.”

“Why do you think she showed herself to me naked?” I asked.

“She wanted to see if you would disapprove. Girls that age like to explore their sexuality, even if they are not in a hurry to have sex. She might do that with your father now and then.”

That night, my wife and I made love more passionately than usual. When we were looking at each other during the afterglow I said, “The thought of my sister has done wonders for our sex life.”

“I think she might be bi too,” my wife said. “I look forward to watching the two of you together. I look forward to you watching your sister and me together.”

My sister was delighted when I told her that I had gotten a paid internship for her at my university. My parents were glad too.

During the rest of the school year my wife and I wrote letters to my sister and called her on the telephone. She was glad to hear from us, and said she was looking forward to the summer. I still did not know if we could seduce her. I did not know if we should. I only wanted that to happen if she wanted it to happen. I wanted her first time with me to be the most wonderful event in her life.

The night of the senior prom for my sister’s high school graduating class my mother called me on the phone. She told me that my sister was depressed because no one had asked her to the prom, and asked me to call back in an hour and talk to her.

When I talked to my sister I told her that I had not gone to the senior prom either. I said that I was not dating anyone regularly. I had made a list of girls to ask. When the first one turned me down I was too downhearted to ask the second one. I told my sister that she was beautiful, but shy, and that the shy boys who were also home alone on prom night, and who wanted to ask her, had needed some encouragement.

After that conversation, I had another conversation with my wife when we were lying in bed together. I told my wife that my sister’s loneliness made her easier to seduce, but increased my guilt for taking advantage of it.

My wife reminded me that we were not going to pressure my sister into doing anything that she did not want to do. When my wife removed her nightgown to make love to me she said, “Do not pretend I am your sister. Know that I am the wife who loves you.”

When summer finally came my sister drove her car to our house with the belongings she would need for the summer, and the fall semester. We helped set her up in our guest room, and drove to a restaurant to celebrate her visit. Those at the restaurant envied me to have the company of two such beautiful females.

“I’m looking forward to using your hot tub,” my sister said.

“Your brother and I are naked when we use that,” my wife said, “but we will wear bathing suits for your visit.”

My sister looked down with a shy smile.

When my wife and my sister helped my sister unpack I noticed that she had a bikini razor. “You told me to bring a skimpy bikini,” she told me. “So I decided to shave my bikini area.”

She was not kidding about the skimpy bikini. That evening when we got into our hot tub her bikini consisted of a small triangle of thin cloth to cover her vulva, and two smaller pieces of the same thin cloth to cover her nipples. These were held in place by strings. The imprint of my sister’s slit and her protruding nipples were clearly visible.

“You are hardly wearing anything at all,” I told her trying to sound mildly disapproving.

“You have already seen me naked,” my sister said, “You are my brother anyway, so it doesn't really matter.”

“I'm glad there is no beach around here for us to take you to,” I said. “I would have to fight off the men with an assault rifle.”

My sister laughed teasingly. “I would not walk off with one of them.” When she saw the erection pushing against the constraints of my swim trunks she looked pleased.

I wanted to lift my sister out of the hot tub and carry her into our bed room. My wife held my fingers and squeezed them in a way that said, “Not yet.”

After this session in the hot tub, my wife closed the door to our bedroom, so that we could have some privacy while discussing the progress of our seduction of my sister. “How do you think we’re doing?” I asked.

“The fact that your sister wore such a skimpy bikini was a good sign,” my wife responded. “It was obvious that her nipples became erect with arousal under that diaphanous cloth. Her body was wet all over because of the hot tub, but I am sure she lubricated. We probably could have taken her, but I would rather draw out the tension. Let’s see how she behaves tomorrow, and see if she projects guilt or pleasant anticipation.

“You've known your sister longer than I have, but I think I have more insight into the psychology of a teenage virgin girl. I am confident that right now she is masturbating thinking about you. As we make love, pretend that I am her.”

The next morning my sister walked naked to the bathroom and back for her shower, as if showing herself naked to me was the most natural thing for a teenage girl to do with her brother. My wife looked knowingly at me, and smiled faintly.

A week later we celebrated my sister’s eighteenth birthday at an elegant restaurant I took my wife to for wedding anniversaries. In the evening my sister suggested another session in the hot tub. This time she suggested that we all be naked, “Because that is what you’re used to, isn’t it? A girl should be able to show herself naked to her brother.”

When my sister stepped naked into our hot tub I was speechless with awe about her beauty, and the possibilities it gave me. She, in turn was unable to say anything about my erect penis, and what I obviously wanted to do with it.

After a long and awkward silence my wife said to my sister, “You are lovely my dear. Your breasts are large, but firm. Your areola’s are perfectly round, and the same delicious shade of pink as your lips. Your nipples are erect with arousal. Your lips and nipples beg to be kissed.

“Your stomach is taut, your waist is narrow, and your rounded hips beautifully frame your shaven vulva. You have a slight mound, a well defined slit, and no clit hood. It does not get better than that.”

My sister responded to my wife’s accurate description of her body by breathing deeply with her mouth slightly open. Finally, my wife said, “I want so much to lick your vagina. May I?”

My sister softly whispered, “Yes.”

When we got out of the hot tub my sister and my wife dried each other off with towels. Then they both dried me. We walked into our marital bedroom. My sister lay on our bed, spreading her legs. My wife’s tongue licked against my sister’s clitoris. My sister responded by tightly grasping the blanket on our bed.

My wife separated my sister’s labia and said to me, “Look, your sister is still a virgin.”

“Of course I am,” my sister said.

When my wife began to blow gently on my sister’s hymen my sister’s face wore an expression of ecstasy. Finally, she looked at my erect penis and said, “Get inside of me.”

My wife got a towel, and said, “You will bleed a little. This will catch your virginal blood.”

I said, “I will put a condom on.”

My sister said, “You don’t need to. Before I came here Mom got me a prescription for birth control pills. She told me she did not want me to have sex, but that if I did she did not want me to get pregnant. She saw how we looked at each other last Christmas. She knew that when I came here for the summer we would probably be doing this.”

“Does Dad suspect anything?” I asked.

“There are things he does not want to know about. I think Mom and Dad understand that because we did not grow up together we do not feel the way about each other most brothers and sisters feel.”

“Before you guys begin, may I take some photos?” my wife asked.

“Yes,” my sister answered.

My wife produced a camera. “First I want a full frontal of you.” My sister stood facing my wife, and smiling. “That’s excellent,” my wife said as she took a photograph. “Now turn around.” When my sister did, my wife said, “You look good from behind too.”

“Thank you.”

“Put your hands on your waist, turn your head around, and smile at me.” My sister did. “Beautiful. Not it’s time to begin.”

My sister lay flatly on the bed, with her legs straight. “That makes his entry more difficult,” my wife said. “Wrap your legs around his body.”

When she did, I began my assault on the fortress of my sister’s virginity. Although my sister was thoroughly aroused, her hymen was a formidable sentry. I was hurting my sister, and asked, “Are you sure you want me to do this?”

“I have wanted this since Easter. Keep pushing.”

I did. When I broke my sisters’ hymen she gave a soft expression of pain that my wife captured with the camera. I pushed my stout explorer deeply into virgin territory where no man or boy had gone before. My wife put aside the camera, and lay next to us. She kissed both of us on the lips, held my sister’s hand gently, kissing it, and offering us words of encouragement. “You are doing beautifully,” she told my sister. Your brother is an expert instructor.”

When my wife could tell that my sister was about to have her first vaginal orgasm, she took a photograph of my sister’s rapturous face.

My sister’s vagina was even tighter than my wife’s was on our wedding night, so my coital movements were slow and gentle. Finally, my wife captured a photograph of my face’s triumphant expression as I filled my sister’s vagina with my life’s fluid.

My sister held me tightly with her arms and legs saying, “Please don’t leave yet. This moment is precious to me. Thank you. Thank you so much. I always wanted my first time to be perfect. This is. This is the best birthday I have ever had.”

When I finally withdrew from my sister my wife told her, “Keep your thighs spread. Sit up on the bed, bracing your back with your arms.” When my sister did, my wife took a photo of her vagina leaking her blood and my semen. My sister’s face wore an expression of pride and sexual fulfillment.

My wife left the room, quickly returning with a bottle of champagne and three champagne glasses. She opened the bottle, filled the glasses, and gave them to us.

“What is this for?” my sister asked.

“We are celebrating your seduction. We planned this last Christmas lying in bed together.”

“My seduction?” my sister asked. “I thought I was the seductress. I wanted to have sex with each of you, but I was afraid it would damage your marriage.”

“Since you have come into our lives our marriage has become more exciting,” my wife said. “Your brother can make love to one of us. Then we can pleasure each other. When he becomes hard again he can enjoy the other of us. The most he has done with me is four times in a single night. Let’s see if we can inspire him to do more.”

“My sister laughed pleasantly, and said, “Other girls can fumble in the back seats of cars with boys who don’t love them. I am having an affair with my married brother and his wife. I feel loved, desired, terribly sophisticated, and delightfully naughty.”
