Learning the Joys of Bisexuality

I always had my suspicions that my sister-in-law might be bisexual and about two months ago I found out my suspicion was correct and I have been having an affair with her ever since.

Jenny is a beautiful brunette with a very sexy body, she's always got some good looking guy trying to go out with her but she is always turning them down and I couldn't figure out why.

I have been married to her brother Michael for almost ten years and during that time I could probably count on one hand how many guys she's been out with during that time. I don't think she has been out with any of them more than maybe two times and she'll go months without a date, or so I thought.

A few months ago Michael went on a weekend fishing trip with some of his friends and I called Jenny to see if she'd like to come over and keep me company. I told her we could hang out by the pool and order takeout all weekend. She said that sounded like a lot of fun and she would love to.

But I had an alternative motive, I was going to find out if my suspicions were true but if they were what did I plan on doing with the information?

I have secretly fantasized about having sex with another female for several years now so did I plan on using that information to maybe fulfill my longtime fantasy?

When she got to the house Friday afternoon she looked hotter than ever, she had on a pair of the tightest white shorts she could have possibly fit into and a tank top that showed plenty of her big beautiful breast. I could feel myself getting excited just looking at her.

We had a couple of beers out by the pool before we ordered a pizza and during that time I caught her several times looking at me in a way like she was checking me out.

After we ate I asked her if she wanted something stronger than beer to drink and she asked what I had. I told her I probably had just about anything she could want and she asked if I had everything to make margaritas.

I told her I didn't but said I had some tequila and we could do shots and drink some more beer. Jenny said she hadn't done shots of tequila in a long time and she wanted to apologize in advance for anything she said or did.

After I got out the bottle of tequila I cut up a couple of lemons and grabbed the salt, I then suggested we go back out by the pool since it was such a nice evening.

After a couple of shots of tequila I finally worked up the nerve to tell Jenny I wanted to ask her something and she said "ask away."

I did another shot and then said "are you bisexual?" A sexy grin appeared on her beautiful face before she asked "why? are you trying to come on to me Lisa?"

I told her I had never been with another woman before and I had suspected for some time that she might be bisexual.

She asked me what made me suspect that and I explained that she hardly ever brought any guys around and I had also noticed the way she would look at me.

Jenny poured us both another shot and after she did hers she said "yes Lisa I have been bisexual since I was in college and lately I have been more interested in other women more so than guys, I hope that isn't a problem."

I told her it wasn't a problem at all in fact I had often wondered what it would be like to be with another woman myself.

I was starting to feel really hot and thought getting in the pool would cool me off. I told her I felt like getting in the pool and I was going to go put on my bathing suit.

Jenny said "I have a better idea, since it's just the two of us why don't we go skinny dipping?" Before I could say anything she had pulled off her shirt exposing the most beautiful breast I had ever seen and her pale nipples were extremely hard already.

She pushed her shorts down and she wasn't wearing any panties and I noticed that she also kept her mound completely shaven.

By then I could feel my own nipples getting hard and I could also feel myself starting to get wet between my legs.

She then asked me if I was going to take my clothes off and as if she had me under a spell I stood up and pulled my shirt up over my head exposing my naked breast to her for the first time.

I then unbuttoned my shorts and pushed them down along with my wet panties so we were both completely naked.

After we got in the pool she started to move towards me and said "if you want I would be more than happy to show you how much fun two women can have together Lisa."

She was now so close our breast were touching and I don't know if it was the alcohol or that I was just that horny, I wrapped my arms around her, pulling her tight and we kissed for the first time. I don't think I had ever experienced a more passionate kiss from any guy I'd ever kissed. I knew what we were doing was wrong but I didn't want it to stop.

As we continued to kiss I felt her move a hand up to fondle my breast and when she pinched my hard nipple I moaned into her mouth letting her know I was enjoying what she was doing to me.

I moved a hand up to fondle another woman's breast for the first time and I couldn't believe how soft and firm it felt at the same time and when I pinched her nipple she moaned into my mouth.

After several minutes she pulled her mouth from mine and said "I think we should go inside because I want this to be a night you will always remember."

I told her I didn't care where we were as long as she made love to me.

We climbed out of the pool and after we dried off we went inside to the bedroom I shared with my husband, her brother.

Jenny had my lay on the bed and as she looked down at me she said "Lisa you look absolutely beautiful laying there without anything on, I have wanted to make love to you ever since you started dating my brother, I just never thought I'd ever get the chance."

She then joined me on the bed, kissing me again as she gently squeezed my breast, I don't think I have ever wanted someone to make love to me more than I did her at that very moment.

She then moved her mouth down to suck my hard nipples as I felt her hand moving down my stomach and I automatically spread my legs for her.

As she started to run her fingers over my pussy she looked up at me and said "you're already so wet Lisa and I'm about to make you even wetter."

She pushed a finger inside me and pumped it in and out for a few seconds before moving it up to rub my throbbing clit and I could already feel myself getting ready to cum.

When I moaned that she was going to make me cum she started rubbing my clit faster and harder until I couldn't take it any longer and cried out I was cumming as a strong orgasm shook my entire body.

As I was coming down from my first orgasm I pulled her mouth back up to mine and kissed her before saying I had never had an orgasm that quickly and I loved it.

She said "oh baby I'm just getting started and before I get finished you're going to cum even harder."

Jenny began kissing her way down my body, stopping to suck each of my hard nipples before continuing her way down my stomach as she moved between my spread legs.

I could soon feel her hot breath on my pussy and I couldn't believe that I could already feel another orgasm building inside me.

She started out by lightly running her tongue over my wet lips moaning she loved my sweet juices and couldn't wait to feel me cumming in her mouth.

She moved her tongue faster before she pushed it inside me and fucked me with her tongue for several seconds. She moved her tongue up and started to flick my clit as my second orgasm got closer.

I was moaning how much I loved what she was doing to me and she was going to make me cum again. She then started to suck my clit as she continued to flick it with her tongue until I cried out "I'm cumming again Jenny, oh baby you're making me cum again."

My second orgasm was stronger and it seemed to last forever and when it finally began to subside I pulled her up, kissing her and I could taste myself on her lips and tongue, making me want to taste her even more.

I told her I wanted to make love to her now and she rolled over on her back, pulling me on top of her and said "you don't know how much I have wanted to hear you say that."

I kissed her before I moved my mouth down to suck each of her hard nipples and she was soon pushing my head down saying "I need you to make love to me with your mouth."

My mouth was now inches away from her pussy and I couldn't believe how beautiful it looked. I looked up at her and said "remember I have never done this before and I hope I don't disappoint you Jenny."

She said "that's not possible" and she then pulled my mouth down on her pussy and I started licking her and I immediately knew this was not going to be a one time thing.

I couldn't get over how natural it felt for me to make love to her with my mouth and tongue and I could soon feel her pussy getting wetter as her body was beginning to shake.

Jenny had both her hands on my head holding my mouth tightly against her pussy as she started to grind her pussy on my mouth. A second later she cried out she was going to cum just before I felt her sweet juices squirting into my mouth.

I continued to lightly run my tongue over her quivering pussy until she tried to pull me back up. I told her I wanted to make her cum again and she said "I would love that baby."

This time I took my time licking and sucking her pussy and when I could feel her getting ready to have another orgasm I would pull my mouth from her pussy, kind of teasing her.

Jenny was soon begging me to make her cum again and I finally did and she came so hard I almost couldn't drink all of her sweet juices.

When her second orgasm subsided she pulled me up and we kissed again before she said "you're an amazing lover Lisa I really hope we can do this again real soon."

I kissed her and then said "we have the next two days to make love to each other and after that we will find a way to get together again."

We kissed again before she moved us into a sexy sixty-nine so we could eat each other's pussy at the same time.

As she ran her tongue over my pussy I did the same to her's and when she started to suck my clit I sucked her clit. I mimicked everything she was doing to me and we were both moaning into each other's pussy until we were both cumming together.

As we laid in each other's arms afterwards she said "if you've never been with another woman before Lisa you are definitely a fast learner, I haven't cum that many times in a long time."

I assured her she was definitely my first and I just didn't want to disappoint her and she said "you definitely accomplished that" and we both laughed.

Over the next two days we made love so much I couldn't tell you how many times either of us came, I just know it was a lot and I don't think I have ever been so satisfied sexually in my life. In fact we had just finished making love in the living room when I heard the garage door open and I knew Michael was home. We managed to hurry up and get dressed before he walked in and asked if we had a good time.

We both said we had a great time and he said he was glad because he was going on another fishing trip in a couple of weeks and he was worried I might not want him to. I told him he could go fishing any time he wanted as long as Jenny would come over and keep me company and she said that wouldn't be a problem.

We managed to get together a couple of times before his next fishing trip and it seems like every time we make love to each other it just keeps getting better.

That first weekend was over six months ago and Jenny and I have been secretly getting together at least one time a week to make love to each other and I don't see us stopping anytime soon.
