Setting the Limit

Last June was a great Month for me. My name is Leeann. I graduated from High School and had my eighteenth birthday in the same week. Lots of family came to celebrate both events.

Most of the Uncles and Aunts stayed at local hotels, because we didn't have room for all of them. My Uncle Fred did stay with us, in our guestroom.

Fred has always been my favorite Uncle. He treats me as if I am older than I am, not like a kid. On this visit, he went a lot further. When no one else was around, he would kid me about being "legal" and he would say we should "keep it in the family."

We would both laugh about it, but I thought he was at least a little serious. He would brush up against my butt whenever he got the chance. When no one could see it, he even goosed me, pushing his middle finger up against my asshole, though my pants of course.

He would say things like "You really look good in those pants. I bet you would look even better without them!"

I would giggle and say, "Stop it! You are acting silly!"

After the week of parties, everyone but Fred left for home. He had another week off, and was invited to stay and enjoy our pool. Fred is my Father's younger brother, I guess he is about forty.

Mom and Dad went back to work on the next Monday, and Fred and I were going to hang out by the pool. I was in my two-piece, which was pretty revealing on my eighteen-year old body. Fred was in his surfer jams, which were pretty young for his age.

He went in to use the restroom, and I went in a few minutes after him to do the same thing. We came face to face in the hallway, and he gave me a hug, which turned out to be way different than a hug from your Uncle.

He was fondling and feeling my butt, and I didn't know what to say. I did notice the bulge in his bathing suit, and I couldn't help myself, I felt it. I said, "My God, is that the Loch Ness Monster in there?"

He gave me a kiss, and said, "Don't worry. It won't bite you."

He went on, "We are alone for the day. I have been dreaming about having sex with you for a long time."

"Uncle Fred! We can't do that! That is incest! And what about if I got pregnant? We would both be done for!"

He said he had other things on his mind.

I said, "You mean you want me to blow you?"

"That would be nice. But there are other things we can do which are even better. I could pretend I am the UPS guy, and make my delivery in the rear."

I was shocked. I said, "I have never done anything like that! I don't think I could!" I felt his cock again, and said, "I don't think you could ever get this thing up my ass!"

I have to admit that I was intrigued. I began to imagine what it would be like. I had never even considered anal sex, but the idea of Fred's cock up my ass was turning me on.

We went back to the pool, and sat and talked about it for a while. I finally said, "OK, I am willing to try. But I have to be in control. I don't know if it will even work."

We went upstairs to my bedroom, and on the way Fred stopped in his room. It turned out that he just "happened" to have some sexual lubrication in his suitcase.

We took our swimsuits off, and I put the lube on his stiff cock. While I did that, he pushed his middle finger all the way up my asshole. I said, "Ouch! That is big enough for me! How in the world am I ever going to be able to take your nine inch cock in me?"

He just said, "Please let me try."

I suddenly had an idea. I took a tube of my lipstick, and I drew a line encircling the shaft of his cock, about half way down. I said, "OK, but do not put it in any farther than this lipstick line!"

He looked a little disappointed, but I guess it was better than nothing. He said OK, but I insisted, "Do you promise?"

He looked unhappy, but he said, "I promise."

I got on the bed face down, and I put a pillow under my hips to lift my butt up for him. I spread my legs so far it was uncomfortable. He put the tip up against my asshole, and pushed it in.

I let out a yelp, but it didn't stop him. I felt the tight muscle at the entrance to my ass stretch to the max, and then it just relaxed. He eased it in farther, and the discomfort went away.

He stopped pushing it in, and just held still. I couldn't see the lipstick circle I drew as the limit, but it felt about right. I guess he is a man of his word.

He began to gently fuck me, just pulling out an inch or so, and pushing it back in. I knew what was going to happen soon.

I have refused to have sex with my boyfriends, because I want to remain a virgin until I get married. I know that is unusual today, but I think it will help to make the marriage last. I don't want to wind up divorced like so many others.

Some of my boyfriends almost exploded, but I steadfastly refused to have any kind of sex with them.

Don't get me wrong, I know as much about sex as any eighteen year old girl. The Sex Ed classes in High School were very informative. I knew all about the semen being ejaculated into the woman. I knew it was full of sperm, which attempted to impregnate her.

So now, as Fred was about to come in me, I knew that it would squirt out in thick spurts, creamy and warm. It was not easy for him to stop at the lipstick limit, but he did. And then he grunted as he came in me.

It felt better than I expected. It was his living sperm, and it was a thrill to feel it shoot into me.

Fred's mature cock and heavy balls aroused me much more than any of the teenage boys ever would have. I was glad I had refused them.

He pulled it out as carefully as he had pushed it in, and we stood up. I knew my asshole would never be the same.

We both felt a little uneasy about what we had done, so we quietly put our swimsuits back on and went back to the poolside.

Just in time, too, as Mom came home. She stopped to pour herself a glass of wine, and joined us at the pool. Fred and I glanced at each other with a look that said. "That was close!"

Mom asked us if we had a good day loafing by the pool. We both said yes.

On Tuesday morning, as soon as Mom and Dad left, Fred came to my bedroom. He didn't want to waste any time at the pool; he wanted to get started.

I was in my pajamas, and he just had on his brief underwear. In a flash we were naked. He had already lubed up his cock, and it was getting harder by the second. I said, "Wait a minute!" and I got my tube of bright pink lipstick. He was not happy, but as before, it would be better than nothing.

I gave him a nice surprise, though, and I put the limiting line an inch or so farther up his cock. I was ready for more too. That made him smile.

I got into the same position as yesterday, but this time I reached back with both hands and spread my butt cheeks. He had stretched my asshole out yesterday. So today his cock slid in very easy.

Still a man of his word, he didn't exceed the limit I had drawn on his cock with my lipstick. It seemed to be enough for him, and he fucked me nicely. When he came, it was another series of spurts and squirts.

We spent all day in my room, and we repeated the act three times, as often as he could recover.

While waiting for him to recover we talked about many things. I asked him if he had ever fucked anyone else in the ass. He was reluctant to say, but eventually he admitted that he had with his wife.

He said he had talked her into it when they first got married, and she agreed to do it as a favor to him. The funny thing was, she became a fanatic about it. She rarely wanted it any other way after that first time.

I thought about Aunt Carolyn in a completely new light. She was a prim, proper, almost sanctimonious born-again type. She had a holier-than-thou attitude towards the rest of the family. I visualized her smug look being replaced by glassy eyed, drooling lust as Fred slid his cock in and out of her asshole.

The next time I see her, it will be difficult to control myself. I will want to say "The next time you are talking to God, would you find out how he feels about people who like to be fucked in the ass?"

We put on swimsuits and went down to the pool in plenty of time to avoid being caught upstairs by Mom. When she joined us with her glass of wine, I noticed that my bikini bottom had a wet spot right in the crack of my ass, and it was growing larger by the minute.

I doubt she would have recognized it as cum, but I didn't want her to ask me what it was. I quickly got out of my chair, and jumped into the deep end of the pool. She was surprised, so I said; "I just needed to cool off." There was a lot of truth to that.

On Wednesday, we started off the same way. I got out my lipstick, and he said, "Do you really have to do that?" I said, "Just let me take care of this."

This time, I drew my line of pink lipstick right around the base of his cock, next to his balls. I said, sternly, "Do not shove it in any further than this! Do you understand?"

We both had a good laugh, and I got into bed. This time I put two pillows under my hips, hoping it would go in even further. It did.

I was apprehensive when it went beyond the familiar territory of the last two days, and entered the unexplored regions of my insides. There was no reason to worry. I was in an erotic dream-state as the last inches went up me.

I did not have an orgasm with Fred during the previous two days, but suddenly I was coming like crazy.

All day Wednesday, Thursday, and Friday we spent in my room. I lost count of how many times he fucked me up my ass. It was heaven.

Sadly, on Saturday he had to leave. We hugged and kissed as we said our goodbye. I was not faking it as I did with other relatives, I really was sad to see him go!

I learned a lot about myself during those days. I began to understand that my previous refusal to have sex was more than a commitment to remain a virgin. It was clear that I was not interested in vaginal sex because I really wanted it in my ass.

Fred came along with a persuasive offer to do it, and my repressed desire came to the surface. Somewhere there is a lucky man who is my future husband. We will have vaginal sex whenever we try to have a child, but for recreational sex I will insist it is in my ass.

As for my immediate future, I am trying to get into a College in the town where Fred lives. I don't care about the quality of the school; I just want to feel his big cock up my ass again.
