In the same manner, these story characters may lie about their age, stating that they are younger than 16. But I am stating here and now, as the author of this story, that every single character is at least 16 years old. Any reference to an age younger than 16 is a lie, stated by the character or narrator of the story in an attempt to shock the reader. But do not believe them. It is not true. They are really 16 years old or older. Believe me. I know. I wrote the story.

Things were progressing fairly well. I had just given Cin her best orgasm ever, with the help of my hand on her pussy. I was letting Cin tell me what she wanted me to do each time, to help make her cum, and I wondered what would be next.

Cin came bouncing back into the living room. “So what do you want to do now?”

“Well you can’t hardly beat what we just did,” I said.

“Yeah, well I’ve had about enough of that for a while. Let’s just rest and watch your movie,” she suggested.

“That’s fine with me,” I told her as I stretched out on the couch. The next thing I knew Cin was stretched out in front of me with her back pressed up against my front. I had to use a pillow to get my head up high enough to see the TV. I would have been fine except that every once in a while Cin would wiggle her butt up against me. It wasn’t too long before I was sporting an erection that I couldn’t help but press up against her butt.

After about a half hour of this fooling around she took my left hand and pulled it over her hips, pressing it up against her stomach, with her hand on top of mine. Slowly she worked our two hands together, downward on her body. I felt her pussy hair first, then her folds. Soon she was slowly moving my hand back and forth across her pussy. She gradually increased the speed such that within a few minutes she was masturbating full force using my hand to do it.

“Oh come on,” she complained. “Why won’t this work? It did before when you touched it.” She suddenly stopped and just held my hand there. She wasn’t climaxing, just thinking. Then without warning she took my middle finger and plunged it deep into her pussy. Pulling it partway out she plunged it in again. She kept repeating the process.

“Cin, we shouldn’t be doing this,” I warned.

“Don’t stop David, we’re almost there,” she begged. I decided I wanted more this time so I wasn’t going to let her cum so quickly. I was finger fucking her on my own now, making her howl with pleasure but not cumming.

I rolled her over onto her back, never stopping my motions to her pussy. I began sucking her breasts again, playing with her nipples. After a while I started kissing and sucking her skin below her breasts, slowly working my way down her stomach. When I reached the top of her pussy hair I announced, “I don’t dare go any further.”

“You can’t stop now, David, please. Eat me David, eat my pussy. I need you to, I want you to,” she kept begging me. So I obliged her. I let my tongue glide across her pussy hair. I skirted around her clit and dove my tongue into the folds of her pussy, never stopping my continual finger fucking. I licked and sucked all around. Her pussy juices were all over my face. I added a second finger and still having plenty of room added yet a third finger.

Cin was beside herself, hovering on the edge of a climax but never reaching it. I decided to try something bold. I lifted my head and said, “Cin sleep.”

Still breathing heavy Cin said, “Yes…David.”

Never stopping my hand assault on her pussy, I said, “Cin, for this one time only, when I touch your clit with my tongue you will have a massive orgasm.”

“Oh thank you David, I need that now,” she said.

“You will continue climaxing until I lift my mouth off of your clit. And the longer you climax the more powerful it will feel. Do you understand?”

“Yes, completely,” she assured me.

“On three you will wake up feeling wonderful, on the verge of a magnificent orgasm. You will not remember this conversation but you will do everything I have suggested. One, two, three.” I immediately went back to licking her pussy, still keeping away from her clit.

“Almost there David, ” she warned me.

“You’re right Cin and this one’s for you because I love you.” With that I moved my mouth up a bit, wrapping my lips around her clit. Rubbing with my tongue I began to suck it.

Cin screamed and grabbed my head with both of her hands. Holding me firm against her she pushed her hips upward and yelled, “Oh hell yes.”

Though I had no intention of stopping my work on her clit, I doubt I could even if I wanted to, she had me in such a grip. Cin was rambling saying, “Oh God, oh God, oh God,” over and over. This went on for several minutes and I decided she had had enough. Pulling her hands away from my head I pulled my mouth back off of her and removed my fingers from her pussy.

Cin collapsed back onto the couch crying. “I can’t believe what just happened. That was the most magnificent orgasm I have ever dreamed of. It just wouldn’t end. And it’s because of you, because you weren’t afraid to help me. I love you David, more than anything. You are just so good to me.”

“I love you too Cin,” and then I kissed her long and hard on the mouth.

“David, don’t get mad, but I want you to come to bed with me tonight. I want you to do this to me again, in my bed.”

“Well I don’t know about you but I need a shower first,” I told her.

“Let’s shower together,” she suggested.

“Are you sure,” I questioned.

“Yes, absolutely.” She took my hand, and grabbing her pajamas, led me to the bathroom. “Now take off those shorts and let’s get in the shower.”

A minute later I found myself showering with my sister. We soaped each other up and washed each other off. It was the first time my sister had touched my shaft. It was full and hard for her so was easy to clean.

“How come you never ask me to help you?” she asked as she slowly slid her hand up and down my erection.

“Maybe someday, but I have a feeling this night is all about you,” I explained. She smiled and let go of my member. We finished rinsing off and then got out of the shower. We dried off and went to her bedroom, leaving our clothes on the bathroom floor.

“I think I need to rest a little while after that last one so do you mind if we just snuggle in bed together for a while?” she asked me, almost apologetically. Now why would I mind snuggling up with my grown sister, nude in her bed, knowing that soon she would be begging me to help her climax?

I must have fallen asleep as the next thing I knew I woke up to Cin masturbating, and she was not happy. When she realized I was watching her she said, “Oh good David, you’re awake. Get down there and start eating me out and finger fucking me. I obeyed and gave her everything I had. I literally tried to make her cum. I even worked her clit a while, only to hear Cin cry in desperation over not being able to climax.

She had me throw off the covers and spreading her legs wide apart told me, “Use three fingers and fuck me to hell and back.” I rammed those fingers in and out of her so fast they were a blur but still I didn’t let her cum. I was so hard myself I thought I was going to burst. Cin saw it too.

“David, wait, stop for a minute,” she said. “This isn’t working. We have to do something drastic. Just this one time and I promise you I’ll never ask you again.”

Anticipating what she wanted I played the game. “No Cin, not that. We can’t. You’re my sister. I can’t do that, please don’t ask me to do that.”

“If there was any other way, but there isn’t. I know this will finally break the spell that has lingered over me,” she begged me. No, she insisted. “You have to do this.”

“I can’t Cin,” I told her.

Continuing her arguments she sat up next to me. Her hand rubbed my arm while she continued to make her case. Then she pressed me back to the bed with a kiss. Before I realized it I was on my back and she was continuing to kiss me as she straddled my hips. Without even saying another word I felt her hips slide down towards the head of my shaft. I began a weak struggle, which only made her more forceful. Without breaking the kiss she slid her body down onto my erection.

Her pussy felt so slick and warm wrapped around my penis. She began rocking her hips forward and back, sliding her self up and down my shaft. I stopped struggling and she broke off the kiss, sitting up on me. I reached up and took her breasts in my hands, squeezing and kneading them, even pinching the nipples.

Cin moaned with pleasure and she kept fucking me. It felt so wonderful, the walls of her vagina grabbing at me as I slid in and out. I soon found myself on the verge of my own climax. Just as I was about to go over the edge I said, “Cin, cum for me.” And she did. She leaned back as I pumped my sperm into her body, one squirt after another. She was gasping. I knew this was a colosal orgasm for her. Her pussy walls were squeezing and letting go, squeezing and letting go, again and again. She kept me hard for the full length of her orgasm which seemed to last several minutes. I then realized that my instructions were that each orgasm would be better than the last.

“Cin sleep,” I said.

“Yes David,” she said.

“Did you know Cin that I was a virgin until now?” I asked her.

“Me too David. I lost my hymen years ago but I had never had sex until now,” she confessed.

“We gave our virginity to each other and no one can ever take that away,” I told her.

“You are right. This will always be something very special between us,” she said.

“And Yvette of course,” I laughed.

“Yes of course,” she confirmed, that she would be sharing the story with Yvette.

“From now on you will be able to climax without my special words. You have earned it. You can now climax normally and your orgasms will be whatever they will be, not necessarily better or worse than any other. The orgasm you just had will be over when you wake up.”

“Thank you David, but I did enjoy your help.”

“I enjoyed giving it,” I honestly told her. “It’s not too late Cin. Why don’t you invite Yvette over for the night? Then you can give her a crash course in self-hypnosis. Work on it tonight until she is able to do it on her own. Then come get me and show me. OK?”

“OK, David. That’s a great idea. I’ll call her right away,” she said.

“When you wake up you will not remember this conversation, just the suggestions that were made. You will think inviting Yvette over was your idea. Now on three you will wake up refreshed. One, two, three.”

“Oh God, that was fantastic,” she said. “I’m sorry if I forced you but I just had to do it.”

“You didn’t force me to do anything I didn’t already want to do,” I told her. It will be our secret.

“Well you know I have to tell Yvette,” she reminded me, as Cin tells Yvette everything. “In fact I think I’ll call her now. I wonder if she would like to come over. I could show her about self-hypnosis.”

As I was leaving her room I heard her on the phone with Yvette telling her the whole thing of how she fucked me and had this incredible orgasm for three minutes straight. There was no question in my mind that before this weekend was over I would be fucking Cin again. Maybe I would get lucky enough to fuck Yvette too.

The End (until Yvette arrives)
