Cynthia has been using hypnosis to lose weight

Cynthia has been using hypnosis to lose weight. Her brother David has implanted a secret phrase that puts Cynthia into a deep hypnotic trance, ready to receive his suggestions.

Author’s note: Every character in or referenced in this story is 16 years old or older. Sometimes in real life people lie about their age. 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.

“Oh God, I’m so embarrassed,” Cynthia said as she quickly put her clothes back on. “I don’t know why I did that in front of you.”

“I thought it was wonderful,” I blurted out. “I loved it.”

“Yeah, you would,” she shot back sarcastically. “Just like a guy to say that.”

By now Cynthia was dressed again and about to walk out of my bedroom. I had to get control of this situation quickly before it all blew up in my face. “Cin sleep,” I calmly said.

“Yes David,” came that monotone voice she had when she was under my hypnotic spell.

“I’m sure you may have a momentary feeling of embarrassment but it will quickly pass. Just know that you gave yourself and me great pleasure and that was the important thing. So everything is fine.”

“OK David,” she said.

“In fact when you think about the pleasure you gave yourself you realize it was the best you have ever felt. Don’t you agree?” I asked her.

“You are right, David,” she said. “It did feel great.”

“Wanting to feel it again you will try once more when you get back to your room,” I instructed her. “But you will not be able to climax. In fact you will not be able to climax at all no matter how hard you try. You will be so frustrated at trying alone that you will come to me and tell me about it, even ask for my help. Even though I will be a little hesitant, you will convince me to help you. OK, Cin?”

“Yes, David. I am always grateful for your help,” she said.

I continued. “Whenever I say the words ‘Cin, cum for me,’ you will immediately climax with an orgasm better than any you have ever had. But you won’t realize that I have said those words. You won’t remember that I said anything at all. You will only know that something I did helped you cum. When you are alone, you will continue to try on your own but will not be successful. You will ask me for help and to do whatever I did the last time that made you cum. If it doesn’t work then you will ask me to do something more daring each time until you reach a climax which I will give you when I speak those words ‘Cin, cum for me.’ Do you understand?”

“Yes David, completely,” she replied.

“After you cum Cin, you will rest a little while, at least a half hour, before trying to masturbate again. I don’t want you to wear yourself out.”

“Thank you for your concern, David. You are always looking out for my welfare.” I really liked the way Cin behaved while under the trance. Though her voice was monotone she wasn’t brain dead. She still evaluated things and responded like she was thinking. I was just able to influence her thoughts, direct them the way I wanted. I had read that you couldn’t make someone do something they didn’t want to do. So my goal was to make her want to do it my bidding as much on her own as possible.

“On three you will wake up feeling refreshed and will not remember that we had this conversion but everything will happen just as I have suggested. One, two, three.” She woke up as if no time at all had passed while she was under my hypnotic spell.

“Sorry David, I’ve got to be alone for awhile,” she said as she left my room.

I just laid there on my bed relaxing, waiting to see how long it would be before she came back in. I only had about an hour before my parents got home from work. But I didn’t have to go to work that night and had all day Saturday with Cin as both Mom and Dad were going away for the weekend on one of their “bonding” weekends. That gave me all Friday night through Sunday afternoon.

Unfortunately I didn’t see Cin until after Mom got home. It was probably a good thing as it gave me more time with her alone after Mom and Dad left. Cin looked flushed and tired and maybe a bit on edge. I wondered if she had been masturbating, trying to climax. My guess was that she wasn’t able to cum.

“Hi honey,” Mom said as I walked in on her packing up for her trip. “Cynthia and you will have to fend for yourselves for dinner. Your dad and I will be leaving as soon as he gets home.”

“Oh that’s fine Mom. We can find something to eat,” I assured her. I wondered if I might be eating my sister’s pussy before the weekend was over. “You two have a great time.”

“Thanks, we will,” she said, continuing to pack her suitcase.

I piddled around in the kitchen but ended up just making myself a bowl of cereal. Before I was done my dad, who had just gotten home, and mom were saying their good byes and took off.

After they drove off Cin came to the table and said, “God I thought they would never leave. David, you have to help me.”

“Help you do what?” I feigned ignorance.

“This is so hard, to be talking with my brother about this,” she said. “Heck, here goes. I can’t cum David. As hard as I try I just can’t cum. After I climaxed for you earlier today I tried over and over but I just can’t cum. I masturbated for nearly an hour straight and just couldn’t climax. I would get close but no orgasm. You have got to help me.”

“Well what can I do?” I asked.

“I don’t know, maybe just watch me,” she said. “I have to try something. I am at my wit’s end. See if I’m doing something wrong, anything.”

“OK, but this is for you, because you asked me,” I explained. “I’m not some kind of pervert that gets off watching girls masturbate. I love you and can’t stand seeing you tied up in such knots like you are.”

“Thank you, thank you,” she said. “Let’s go to my room. I have to know that I can cum in my own room.”

“Fine,” I agreed. I left my cereal half eaten and followed Cin to her bedroom.

“I hope I’m not making a habit of this,” she chuckled lightly as she removed her pants and panties.

“Maybe you just need to be more relaxed,” I suggested. “Why don’t you get rid of your top as well? Then you won’t be hindered by any clothes.”

“Well, OK, but can you turn around?” she asked.

“Cin, I can already see your pussy. Do you think it’s going to matter if you show me your boobs too?” I asked her.

“Kind of stupid huh? OK, fine,” she conceded as she removed the rest of her clothes, bra and all.

This was the first time I had ever seen my sister’s breasts. They were full, even on the large size. I’m sure this was some of the area she wanted to lose weight in. Her skin was light all over, her areolas a darker pink and very large. In the middle of each she had a large nipple that seemed a little puffy right then, maybe swollen but not hard looking. Maybe it was from all the near misses she had at masturbating.

“OK, now show me what you have been doing,” I suggested.

She began rubbing her pussy and I could see that she was already wet. After a few minutes she said, “It goes like this and I get close like now but just can’t quite make it happen.”

“Do you mind if I try something?” I asked.

“Please do,” she agreed.

“Keep doing what you are doing and I am going to try a few things. Please don’t try to stop me, just let things happen,” I told her. “Trust me.”

“I’ll get mad at you later,” she laughed. “Just help me.”

I leaned in and kissed her on the mouth. She didn’t resist, but of course no climax. I kissed her again, a little longer this time, like we had done in my room earlier.

When I pulled back she suggested, “Try squeezing my breast with your hand.”

“Are you sure?” I asked. “That’s going a bit too far don’t you think? You’re still my sister, not some street whore.”

“Just try it, please,” she begged, continuing to stroke her pussy.

I took both hands and squeezed her breasts for about half a minute. “That feels good,” she said. “Yes, that’s nice. I like that.”

Then I softly said, “Cin, cum for me.”

“David, I’m cumming, I’m finally cu…oh my God, ohhhhhh shit,” she exclaimed. She was clearly in the thralls of a massive orgasm. My post-hypnotic suggestions had clearly worked. After half a minute her hand stopped rubbing her pussy and she just kept her eyes closed, not saying anything. Her breathing was labored but was slowly getting back to normal.

Cynthia opened her eyes and said, “That was fantastic, thank you so much.”

“Your welcome. But don’t think I’m going to be doing that for you all the time,” I cautioned.

“Of course not,” she replied. “I just needed to get past some blockage I had. Now that I know I can climax again, I’ll be fine. Hey, throw that cereal out and I’ll fix you a real dinner.” She did too. Afterwards she said she was tired and wanted to just shower and relax.

After she took her shower I too mine, put on some pajama shorts and a t-shirt and went out to the living room to watch some TV. I found my sister masturbating on the couch, frustrated as all get-out again, and unable to climax.

“You’ve been doing that a lot lately,” I told her.

“I don’t know what the problem is,” she said. “I couldn’t cum in the shower. I can’t cum here now. I may need your help again.”

“OK, but this is the last time,” I warned her, knowing it wouldn’t be. I sat down next to her on the couch and while she rubbed her wet pussy she had me slowly kiss her on the mouth. I savored the taste of her luscious lips. This time I continued to kiss her as I let one hand massage a breast. I pinched a nipple as my tongue slipped into her mouth. She moaned in response as I gave her other breast equal time. Breaking the kiss I massaged both breasts as I had done earlier today but I didn’t let her cum.

“I don’t know what the problem is,” she wondered out loud. “This worked before. I mean it feels so good but I just can’t cum. Maybe if you sucked on them, sucked on my breasts. Yes, try that David, please.”

“Are you sure Cin?” I asked hesitantly. “This is well, pretty extreme.”

“Please David, just do it,” she insisted.

I obeyed. I leaned in and lifting one of her large breasts I put as much of it into my mouth as I could and sucked hard, letting my tongue dance around her nipple as I did. While doing this I continued to massage her other breast. I was in heaven. Here I was sucking on my sister’s breasts, at her request. I changed to the other breast and gave it equal time. A couple of minutes had gone by and I decided to finish this.

Pulling off her breast I said, “Cin, cum for me.” And did she ever. She instantly gasped and thrust her hips upwards. Her hand increased its speed on her pussy and she was clearly having another massive orgasm. I decided to continue to suck on her breasts while she climaxed and was surprised at how hard her nipples had become. I twisted, pinched, and sucked on them until she collapsed back down to the couch exhausted.

“I guess that worked,” I told her as I released her breast.

She laughed. “Yes, I guess it did. Thank you again.”

“Just relax. I’ll get you some water.” I needed some myself. When I got back I handed her the water and said “Cin, sleep.”

“Yes David,” Cin said in her hypnotic voice.

“You have had some nice orgasms haven’t you Cin,” I asked her.

“Oh yes, better than ever before, thanks to you David.”

“After you rest a while you will want to masturbate again, to get that wonderful feeling again. You won’t feel inhibited about masturbating in front of me ever again because you have done it several times already.”

“That makes sense, especially since you have helped me so much,” she agreed.

“You will always get to that point where you are so frustrated that you ask for my help, and I will be here to help you,” I promised her.

“Thank you David. I know I can always count on you to help me,” she droned.

“It’s because I love you and I always want the best for you,” I told her.

“I know that David, and I always want the best for you too.”

“But in helping you masturbate Cin, I don’t feel as relaxed about it all as much as you do and I may resist helping you. You will ask me to do things that a brother shouldn’t normally do with his sister. So you may have to use a little forceful persuasion to get me to help you. That’s OK, as long as you don’t hurt me.”

“I would never hurt you David. But I understand your reluctance and will act accordingly.”

“Cin, one more thing. Before you start masturbating again tonight I want you to call your friend Yvette and tell her all about your masturbating, the problems and how you have convinced me to help you, and especially how wonderful I have made you feel.”

“That’s a good idea David. I’ll call her right away.”

“On three you will wake up and as usual not remember our conversation but will do all that I have suggested. One, two, three.”

“Oh thanks for the water David,” Cin said. “Hey if you don’t mind I’d like to go call my friend Yvette and just chit chat. I’ll see you after a while.”

“Sure, I’ll just watch some TV,” I told her. “Tell Yvette hello for me.”

About a half hour later Cynthia came back into the living room and sat down next to me. She had on her pajamas but without even asking she slipped them off and began to gently massage her pussy. “What are you watching?” she asked, as if she wasn’t doing anything out of the ordinary.

“Oh some dumb movie,” I replied. “But I’d much rather watch you.”

“I see that you would,” she said nodding to my new erection pushing up against my pajama shorts. Though I have had plenty of hard ons recently while helping my sister masturbate, this was the first time she made any comment about it.

“Just ignore me and keep doing what you’re doing,” I said.

“I think you like watching me and are afraid to admit it,” she argued. “Yvette said you would. All guys would. It’s OK. I don’t mind. It’s not like we are fuc…I mean having sex or anything. You are just helping me when I get in a rut. So just sit back and enjoy. I’m going to show you how it’s done.”

I did too. For the next 15 minutes I watched as my sister got more and more frustrated at not being able to cum.

“Damn it,” Cin exclaimed. “I thought I could do this on my own. It looks like I may need your help again David. I’m sorry. I know you don’t like having to do this all the time. But I really need your help, please. I am so close.”

“Don’t be sorry. You know I love you and would do anything for you. I don’t like seeing you so tied up in knots. So what do you want me to do?” I asked.

“Just do what you did last time,” she instructed. “It’s OK. I don’t mind.”

“Lay down on the couch this time and I’ll kneel down next to you,” I told her. “Yes, that’s it.” I leaned in and kissed her again on the lips. She took her free hand, the other was rubbing her pussy, and put it behind my neck. Pulling me hard into her she quickly sent her tongue into my mouth. She wasn’t wasting any time. I put one of my hands on a breast and began massaging it.

Breaking the kiss, she said, “Suck on them, please.”

While still massaging her one breast I took her other one into my mouth. This time I stayed with her as I felt her nipple grow hard in my mouth. I knew she was ready to cum if I would let her. Her other nipple was hard to my touch and I moved my mouth to it, licking and sucking, but not letting her cum.
“It’s not working. I don’t understand,” she complained.

“Well there’s nothing else I can do Cin,” I told her.

“It’s not you. What you are doing is fine. It feels really good, honest. I’m just not cumming.” After a short pause she suggested, “I want you to rub me, down there.”

“No, I can’t do that,” I objected. “You’re my sister for God’s sake. I’ve already done way too much already.”

“You have to, please David, just this once,” she insisted. “I’m so close. Please.”

“No way. Absolutely not Cin. I won’t do it.”

“God damn it David, give me your hand,” she said as she grabbed the wrist of my right hand. Just as quick she yanked my hand down to her pussy and began rubbing herself with it.

The moment my hand touched her dripping wet pussy I said, “Cin, cum for me.”

“Oh God in heaven, I’m cumming,” she yelled as she thrust her pelvis up into the air. She held my hand to her pussy, not rubbing anymore but just holding it hard against her soft folds and wet curly hair. After about a minute she collapsed back to the couch and released my wrist. “That was the most magnificent orgasm I have ever had. Thank you, thank you, thank you David. Wait until Yvette hears about this. David, give me the phone.”

“Now? You’re not telling her what I did are you?” I asked.

“Yes, give me the phone,” she insisted. “I tell Yvette everything. It will be fine. Don’t worry.” All I heard was Cin’s side of the conversation. After the initial explanation of what just happened it went something like this. “Don’t be ridiculous. Of course he’s not a pervert.” Cin smiled at me. “He didn’t want to…That’s just it. I had to literally force him…Of course I love him…Well not like that. He’s my brother for goodness sake…I wouldn’t mind…Yeah, it would be kind of cute, you and him…yeah…The weight thing is going really good…Sure, it works for anything. If you want to gain weight or lose it…Yeah, I could show you…OK, later then, bye.”

“Thanks again, David,” Cin said. “It looks like I need to clean up again. I’ll see you in a little bit.” She grabbed her pajamas and took off for the bathroom.

I just laid on the couch thinking about what was coming next. I didn’t want to move too fast. But I did want to taste her pussy. I had thoughts about going all the way but then dismissed them as being too extreme, or could I? What should I do? Should I get her to start working on me? Go for broke and just fuck her? Maybe I should get her to call Yvette over for some self-hypnosis training. I would love to implant a command in her to put her into a hypnotic state at will.

I had so many possibilities.
