Chapter 1: The Arrival

It was early summer when I received the panic phone call from my husband's older sister. Clair was quite upset, she went on at length about how Nancy, her daughter and our favorite niece, had started "behaving very strangely" lately and was "running around with a worrisome crowd", at least in Clair's eyes. Nancy had been dressing very "provocatively" and Clair had caught her openly masturbating on several occasions. As I listened to her go on at length, it seemed to me that Clair was a little hysterical, making a mountain out of a mole hill. I thought it seemed perfectly normal for a 15 year old young woman to enjoy masturbation, even on a regular basis. I was a year younger than that when I started masturbating on a regular basis, plus doing a hell of a lot more. But I kept my silence and just listened as she expressed her "serious concern". Inside I was pleased that our skinny little sweetheart of a niece had started to mature.

Then the reason for her call came out, Clair was wondering if Nancy could come spend a few weeks with us, since "we had always had a way with Nancy". Maybe a change of scenery would help, she opined. I thought to myself, at least no one here would give her a rough time about doing something so natural.

Jim, my randy husband, Clair's younger brother, was sitting at the kitchen table watching me, wondering what Claire was saying. I told Claire to hold on a moment and related all she had said quickly to Jim. He agreed with me that it would be great to have Nancy spend some time with us and Nancy was soon on her way.

If Clair had only known what was to transpire that summer she would have been glad for Nancy to just play with herself. But who knew?

We hadn't seen Nancy in over a year and we were in for a delightful surprise. When she got off the bus we realized she had turned from a cute skinny little girl into this voluptuous young, sex pot. I was stunned by the changes. The cute little girl was now an incredible looking, head turner. Even in sloppy jeans and a t-shirt (it was clearly evident she wore no bra) her young extraordinary figure was obvious and very appealing to both Jim and I. (I had discovered the advantages of being bi-sexual years earlier while still in college). Only her face appeared so beautifully innocent.

I got a kick out of the way Jim stared at her. If Clair had seen how her brother enjoyed looking at his niece's big tits, bouncing and swaying so nicely, she would have had a fit. If she could have read my mind she would have panicked for sure.

As we rode back to the ranch I had a good idea what was going on in my Jim's head. He was a sucker for teen age girls. Jim and I, from the beginning of our relationship, had shared all of our sexual fantasies with each other. He had told me about his favorite fantasy, which was for this really beautiful, well built, sexy, and emotionally advanced teenager to seduce him. He resists in the fantasy but ultimately gives in and fucks the sexy teenager. While they are going at it hot and heavy, I walk in on them but instead of being upset I join them in a really torrid threesome.

Now here in the flesh was Jim's fantasy girl. Jim and I had realized a lot of our fantasies over the years. I have to say, Jim's fantasy was one we both wanted to make happen someday. Maybe our sweet Nancy's visit was a golden opportunity.

It was late when we got back to the ranch. I helped Nancy unpack her things and get settled a bit. Then, without comment, she stripped out of her jeans and t-shirt, all that she had on, with no qualms and said,

"Aunt Liz, I hope you guys don't mind nudity. I really hate to wear clothes when I don't have to. That was one of the things that drove my folks up the wall."

She continued walking around the room completely nude for a few moments. I enjoyed the views I had of this incredibly lush teenage body, then she flopped on the bed. At that point I stood up and leaned over to kiss her goodnight saying,

"Nancy my sweet love, when you are with Jim and I, you can just relax and do what ever comes naturally for you. Don't get us arrested but feel free to be yourself. Jim and I don't mind a little flesh. You may catch us running around nude too. Although Jim's eyes will drop out when he sees you nude. You have really developed into a sexy young filly."

She giggled softly and said,

"Thanks Liz... I knew I could count on you and Jim to be cool. Do you really think Jim will be pleased at how I have changed? How my body has developed?"

"Oh yes Nancy... he will be more than pleased... much much more. You have to remember that tho he is your uncle he is also a very virile man. And all the men I know will react to this hot body of yours in a very predictable way. Goodnight sweetheart tomorrow we will talk a lot about you and your Mom and us."

As I walked toward my bedroom to wait for Jim I was surprised at how turned on I was. Nancy's young body was even more impressive nude than I had previously thought. Her large melon-like breasts stood out firmly. Her tiny waist nipped in and then flared out in full hips, add incredibly rounded tight buttocks and a lovely fully haired pubic area. Her long trim legs were just as perfect. I wondered, when Jim sees his niece, like this, so delightfully nude, what might run through his head. I knew what was running through mine. I left her door wide open, Jim would be coming upstairs soon and he would drop in to say goodnight to Nancy. I grinned to myself as I anticipated his reaction when he saw his sexy niece so exposed.

She and Jim and I had always been very close. We were her favorites and she ours. We had always treated her as an equal and she loved it. Now I anticipated how the relationship might further develop.

I stripped and crawled into our bed waiting for Jim. I was already so wet I was dripping. I knew we would be "busy" shortly after Jim came from Nancy's room. Hell she turned me on. Jim would be hard and ready I knew. It wasn't long until Jim joined me with this shit-eating grin on his face. He looked at me and said,

"Liz you won't believe this. Nancy was completely fucking bare ass when I went in to say goodnight. What a body that kid has... she is one sexy young lady. When I walked in and stood there dumb struck for a moment she just smiled and looked up at me and seemed to enjoy the way I was staring at her big tits. I stammered a goodnight and leaned over to kiss her cheek. Only Nancy raised up and met my lips with hers in a soft but not so innocent kiss that lasted a little bit too long. Then I hastily said goodnight and left the room. I was afraid my hard on would show, I'm sure it did in fact."
