My sister would always follow me around, and I considered her a pest. Even though she was fourteen at the time, while I was sixteen. What I am about to tell you really started at the beginning of our summer vacation.
My father had rented a cottage on the shores of a lake in a resort area not very far from the city in which we lived. While my mother remained with us at the cottage, he would commute to work every morning and return at six in the afternoon. One day, my sister begged my mother to let her have five dollars so that she could go to PineHill and buy a ticket for a rock concert organized by a group of the local rockers. PineHill was barely half a mile from our cottage, and we often went there on foot or on our bikes. But she hadn’t done any of her chores during the week, and my mother, so as to punish her, refused to let her have her allowance money.
Then Peggy, in desperation, came to see me and asked me to lend her the money.
“Please Jack, lend it to me, and I will give you back ten dollars.”
“No, Peggy, you will never own ten dollars long enough to give it to me, and besides, you never do anything for me when I ask you. So why should I lend you the money?”
I could tell that she was very disappointed, and she wasn’t going to give up that easily.
“I will do anything you ask if you lend me the money, please,” she went on.
“Like what? You know perfectly well that the only things we do around here are to clean our own rooms and mow the lawn, and you don’t even do any of these. As for having you clean my room, well, no, thank you very much. I don’t want you to touch anything in my room.”
She was now desperate, and I think that she was on the verge of crying. I was about to give in to her and let her have the five dollars when she suddenly added.
“I will do anything at all for you if you let me have the money; all you have to do is name it.”
Since I was going to lend her the money anyway, and wanting to know exactly how far she was really going to go, I then added more as a joke than anything else.
“Well, if you kiss my butt and lick it all over, I will lend you the money.”
She looked at me for a few seconds. I could tell that there was shock written all over her face, but I was in for a greater shock when she replied, “OK, I will do it.”
What had been said as a joke, she had taken seriously, and she was now ready to do what I had dared her to do.
I was about to tell her that I was only joking and not to worry since I was going to lend her the five dollars anyway when I began to feel my cock growing inside my pants.
I will always remember that moment. It was in early morning, and we were sitting on a log near the water of the lake. At the time, she was wearing a yellow short and a white tank top that did much to reveal the fact that she had large breasts underneath, even though she was only fourteen. I must add here that Peggy, although not fat, was on the plump side, but since she had lost her baby-fat and had long legs, it made her look sexier, with a woman’s body.
Of course, she had never gone out with a boy yet, and I was aware that she knew nothing about sex.
I looked at her as she sat next to me. She had agreed to kiss and lick my butt, and this made me look at her in a brand-new perspective. I was now looking at the girl in her and not the sister.
Until then, I had never seen her naked, and even though I sometimes wondered how her breasts would look, I had never felt any urge to try to see her tits.
I wanted to know if she was making fun of me, and I asked her when she was going to do this.
“I can do it right away,” she said. “Or if you prefer, give me the five now, and anytime you are ready, I will do it.”
She was serious, I could tell. Hearing her talk like that was all that my cock needed. I felt it twitch in approval while it became as hard as the log we were sitting on.
“I don’t trust you. Once you have your money, you won’t keep your promise.”
“OK, then I will do it before you give me the five.”
It then occurs to me that this was a form of prostitution. She was willing to do sexual favors in return for money. I was now very excited, and since I was not really sure if she was joking, and if she was not, I wanted to know just how far she was willing to go. I added,
“Five dollars is a large amount just for a few licks on the butt.”
“You are the one that set the deal. I can do anything else you want if you think it is not enough.”
“What do you have in mind?”
She didn’t answer right away, and I could tell that she was trying to think of something.
This was getting out of hand, but there was no way that I was going to stop it. My cock was now twitching continuously in my short pants, and I knew that I was on the verge of exploding. This was fantastic; just talking dirty with my sister was having such an effect on me.
She then went on, “Well, I can lick you all over if you want?”
Wow, was I hearing right? Did she really mean this? Was she offering me a blowjob for five bucks? But how could she know of such things? Then it occurred to me that two of her friends were older than her, and one of them, Vicky, was even going out with older boys, and she had a bad reputation around school. She must have learned these things from her, I told myself.
“Where will you lick me exactly?” I said.
“You know. I will put my mouth on your thing and suck on it until it explodes.”
Was this my little innocent sister talking to me? I was stunned, but at the same time, my cock was jerking in approval. I didn’t know what to say to her.
For half a second, I felt a little guilty about the whole thing, but only for a very short time.
My face must have been very red, and I could feel my heart beating exceedingly fast. Then, before I could think of anything else I was saying, I said, “Where will we do this?”
“Let’s go under the cottage. No one will bother us there, and we will have all the time we need.”
The cottage was a wooden structure built on cement posts. The first floor was about four feet from the ground, and all around the foundation there were crossed sections of green panels of wood with holes in them. One could enter underneath by means of a small door at the back of the cottage.
Yes, it was a good place indeed since we would be able to hear Mother walking overhead, and we thus could tell where she was and even what she was doing.
But there was one problem. There was no way that I could walk there with a tent pole in my shorts. Even if Mother didn’t see me, I wasn’t ready to show Peggy that her idea was exciting me that much.
“We will meet there in fifteen minutes,” I told her.
“Yes, but don’t forget about the five dollars.”
With this, my sister stood up and walked toward the cottage. Ten minutes later, with my cock as hard as ever, I slowly walked toward the back of the cottage. After looking around to make sure that Mother was not watching me, I opened the door that led under the cottage, and once inside, I closed it back so that from the outside it would look normal.
Peggy was already there, waiting for me. She was sitting on a cement block, and as soon as I was close to her, she whispered to me to remove my pants.
“No, I don’t think it’s a good idea. If we should have to leave in a hurry, I won’t be able to do so with my pants off.”
“As you wish. But you will have to at least lower them.”
Now that she was about to do this, I was not so sure that it was a good idea. Besides, I still had scruples about exposing myself in front of my sister.
But before I had time to think more about it, Peggy reached for my short pants, and she began to unbuckle my belt. I was seated next to her on another cement block, and once she was done with my belt, she had trouble with the hook just above the zipper of my pants. The pressure of her hands over the front of my short pants as she finally unhooked them and then when she pulled down the zipper was quite enough to convince me, and with my help, we slipped them down around my ankle.
A few seconds later, she reached for the front of my underwear, and she began to fondle my very hard cock. I could tell that she was very excited as she did this. Soon, she had her hand inside my underpants, and I had to restrain myself so as not to climax right there.
Her hand went on to explore the length of my cock, then she reached for my balls, which she squeezed - a little too hard for my taste. Next, she pulled my underwear below my knees. I was now sitting bare butt on a pile of blocks, but I was also one block higher than she was so that my cock was exactly level with her mouth. The instant that I felt her lips around the tip of my penis as she held it tightly with her hand, I exploded into her mouth.
At least the first gush went in her mouth. She pulled my cock out of her mouth as soon as she felt my semen erupting. Then four or five gushes jetted all over her face while she just remained still as though frozen.
But much to my surprise, she once again opened her mouth around the head of my erection and she began to suck.
Even though I had just had a climax, I could feel my juice boiling in my balls while the most wonderful sensation took possession of my body.
Most erotic of all was the sight of my young sister with my cum dripping all over her face while her mouth was wide open around my erection. Her eyes were examining my face, trying to detect signs of the crisis that she was expecting.
