"Yes."

"Do you jerk me off?"

There was a delightful (if short) pause, and Lucy shook her head. I had been expecting that, but it was still worth a try.

"Why not?"

"Your arms are working fine. You can do it yourself."

"Since you stopped jerking me off, or talking me through it, have you thought about it much?"

There was another short pause, and then a quiet "Yes."

"Would you tell me how often?"

"Yes."

"How often?"

"When you come and tell me that you've just jerked off. Every time you come and thank me, I remember."

I'd completely forgotten about that. It was part of the "broken legs" story that had caused her to hypothetically jerk me off in the first place--I'd mentioned that I came and thanked her, each time I came.

Since it was part of that story, and I'd convinced Lucy that the events leading up to her jerking me off had actually happened, as far as Lucy was concerned...it was reality. That meant...that meant that I could actually do that in real life. Like, when Lucy wasn't under.

The idea of coming to tell Lucy that I'd just jerked off, actually doing it for real...it got me hard straight away.

But I stayed on task. I had a plan, and I was going to follow it.

Session 35:

"You'll come and tell me when you masturbate, won't you Lucy?"

"Yes."

"Why?"

"Because I want you to know how horny you make me."

"What else will you tell me?"

"I'll tell you exactly what I thought about. I'll tell you what was running through my mind when I came."

"What else?"

"I'll tell you how I touched myself. I'll tell you whether I used my fingers or a toy."

"And?"

"And I'll thank you."

Session 17:

"You've never stayed in a hospital, have you Lucy?"

"No."

"Well I have, and I can tell you--they don't let you have tissues near your bed. And if I jerked off myself, they'd find the wet patch in my hospital clothes, or in my bedsheets...it would be really embarrassing. Do you understand?"

"Yes."

"I explain this to you in the hospital. What do you say?"

"Oh wow," my sister said, her normal tones delighting me, as they always did. I loved her monotone, but having her sit in front of me like that, under my control but using her normal voice...I don't know why, but it gave me such a thrill. "That really sucks, bro."

"I ask if you'll help me out, and jerk me off. What do you say?"

"How will that help?"

If I'd been improvising, that probably would have stumped me. But I'd been thinking about this for a while--most recently a few days ago, looking down and watching Marcie's head bob up and down on my cock--and I had an answer.

"You could swallow my cum. Do you agree?"

There was a long pause, and my sister started twitching. I really didn't want her to wake up--I was already worried about her or Marci mentioning my extended hospital stay in front of Mom, or one of my friends--adding an inexplicable follow-up stay would have made everything that much harder--but fortunately, she calmed down after a minute or two.

"No," she said, and I sat back in disappointment. From cum-swallowing to blow-jobs was, I was fairly sure, a short path, but it didn't seem like I was going to be able to make that first step.

I considered waking her then and there--I had some other methods that I wanted in the middle of trying out on Marcie first, and I had already gotten uncomfortably close to waking my sister up once...but I had an idea.

"Would you help me smuggle out my cum, if I jerked myself off?"

There was a pause--not long enough to be worrisome, just a short pause--and Lucy nodded.

"Would you watch me masturbate, while I did?"

Again, a short pause and then a nod. Interesting. A few months ago, I never would have imagined myself in this position, but it seemed that my sister Lucy was more than happy to watch me jerk off, if the circumstances were right.

"Would you tell me if you'd enjoy it?"

"Yes."

"Would you enjoy it? Watching me masturbate?"

"...yes."

There was something there, but I didn't have a clue what to do with it. So I retraced my steps, hoping that it would provide me with inspiration.

"So if I were in hospital, horny and unable to get release, you'd watch me masturbate and help smuggle my cum out?"

"Yes."

"Will you smuggle it in your mouth?"

Pause.

"No."

"Will you smuggle it in your handbag?"

"Ew. No."

"Will you smuggle it in your hair, under your hat?"

"No."

No pause before that one. It was, I had to admit, a bit of a long shot.

"Will you smuggle it on your skin somewhere?"

The twitching began again, which had me worried that I was playing too fast and loose, but when it subsided and she whispered another "yes", my heart leapt.

"You'll let me cum on your skin?"

"Yes. As long as I can cover it up with clothes until I get home and get to have a shower."

I could have aimed for the legs, or her arms, but I had an idea, and I decided to throw caution to the wind.

"Can I cum on your tits?"

After what felt like the longest pause of my life, she answered.

"Yes," my sister said. "I'll let you cum on my tits."

Session A8:

"What would you do, Mom, if you found Lucy and I in a room together, naked?"

"I'd be shocked."

"What if we told you that we were just huddled together for warmth?"

"It would still be shocking."

"Recent studies have shown that contact between two naked people is one hundred times more effective than a blanket."

"That doesn't mean it's okay to do that with your sister..."

"Why not?"

"Well...because..."

"..."

"I don't know."

I smiled. I'd found a gap in my mother's knowledge, and if there was one thing my mother loved, it was learning...

Session 17:

So my sister was okay with me cumming on her tits. Only in that extremely specific scenario, I should add, else my cock would have already been out.

The image of my sister, sitting in front of me, her tits covered in my cum...it was one of the sexiest things I'd ever imagined. Before I woke her up, I got her to repeat the statement a few more times.

"I will let you cum on my tits."

"Again."

"I will let you cum on my tits."

"Again."

"I will let you cum on my tits."

It's possible I had her repeat the statement a few times while topless as well.

The session hadn't brought me to the blow-job that I'd hoped was coming, but it was the first step down a very specific path. At that moment, almost more than anything, I wanted to blow a load on my sister's chest. I don't know why I found the idea so erotic, but I knew that I had a new focus. And I thought I knew just how to get there...

Session B16:

"What did you dream about last night, Marcie?"

"You. Again."

Those two words, so mundane, normally so inconsequential...in that order, in that situation, they were two of the hottest words I'd ever heard.

As much fun as fooling around with Marcie was, it wasn't what I truly wanted. I wanted my sister, and Marcie's most useful asset was as a test subject--before I risked screwing things up with Lucy, I tested them out on Marcie first.

And last week, I'd had an idea.

Session B14:

"What do you normally dream about, Marcie?"

"Y'know. Normal stuff. School, work...boys."

"Do you ever dream about me?"

"Not really, no."

"But you could, right?"

"Yeah, I guess."

"Okay. Hypothetical for you. You have a dream. It's about me. I'm holding a collar, and it's got your name on it..."

This was another one of the fantasies that Marcie had shared with me. I wished I had the same access to Lucy's fantasies, but she still refused to tell me the specifics of what she thought about when she masturbated.

I continued to tell Marcie her own sexual fantasy, but as a dream, with me as the central character. I reached the end--her breathing was heavy, and a crimson flush was creeping up her neck.

"...and we turn around, to see your entire church staring at us. You're super embarrassed, but I don't stop. Just as you're about to cum...you wake up."

She slumped in disappointment, and I quickly continued, not wanting to lose the momentum.

"You wake up, and I'm there, in real life. I ask you if you want to fuck. You say...yes."

As I'd expected, there was a lot of twitching. I don't know why Marcie had such a specific block when it came to going all the way, but I'd found it extremely useful--it was a handy limit that I could use to wake her up when needed.

Just as I was sure she was finally going to answer "yes", her eyes fluttered, and focussed on me. She looked disoriented for a second, but then her eyes flickered down to the tent in my pants.

"Oh hey you..." she said with a wink, and a few minutes later, those beautiful lips of hers were wrapped around my cock.

Session B16:

The next session had been more of the same, but I'd been careful to describe it as a recurring dream. "Every night," I think I said.

See, I still haven't worked out a way to give anyone direct commands, except for when they're under. If someone would blow me in real life, I can get them to do it when they're hypnotized...but I can't say "Hey, when you're awake, you'll have a desire to wear a bikini 24/7."

I only have power over their subconscious, for whatever reason, and even then it's only to get them to do stuff that they'd already do. Anything that's believable is possible, but only in specific circumstances.

But that had got me thinking...what if I could control their subconscious, even when they were "awake"? And it was that train of thought that had led me to dreams...

Now I don't know how powerful dreams are in other people...especially girls. But I can tell you, there have been a few times when I've woken up from a particularly hot dream with a hard-on for something I'd never be into. I once dreamt that Lucy had a foot fetish, and for the next few days, I found myself getting off to more than a few pictures of girls getting off to men's feet.

It didn't last long, but all I needed to do was plant a seed. And Marcie had just proven to me that the seed was able to be planted.

"What did you dream about?" I asked, and sat back for the next few minutes as Marcie told me a lewd series of fantasies that involved me fucking her in the front of a classroom, on a golf course, and in some rare owl sanctuary, of all places.

None of these, I should point out, were dreams that I'd planted. I just told her that she had sexual dreams about me all the time, and her kinky brain had done the rest. But the ultimate question was still ahead of me:

Would it work on my sister?

Session 18:

"Would you tell me what you dream about?"

"Yes."

"What do you dream about?"

"When?"

Damn it, Lucy. Marcie was so much more obedient, in so many ways. If Lucy was half as pliable as Marcie, I'd have been fucking her a long time ago.

Though I had to admit--the challenge was half the fun.

"What did you dream about last night?"

"I don't really remember many of the details. I think I bought a dog, or found a dog, or something like that. And I was taking it past a bakery, or maybe just a windmill, when we found something and I had to end up leaving it there for some reason."

Wow. You know how listening to people's dreams is boring? Add a monotone. I was half-tempted to get her to take her top off, just to give me something interesting to look at, but I didn't know how she was going to react to my next move, and having her wake up topless would be pretty tricky to explain.

"Do you ever dream about me?"

"Yeah, sometimes."

"Would you tell me the dreams?"

"Yes."

I asked for details. Of course I asked for details. And even as I did, I regretted it. The next few minutes consisted of a series of half-stories, some of which I only appeared in once. None of them, of course, were sexual. When she was done, I tried to shake off the boredom and kept going with my plan.

"Would you talk to me about sexual dreams?"

There was a long pause, but she eventually answered.

"Yes."

I think our sessions had actually been good for my sister, in a way--she'd really loosened up a lot.

"Would you talk to me about any sexual dreams you have involving me?"

"No."

"What was the last sex dream you had?"

I won't share the details, but it was equally vague and incomprehensible--apparently Lucy doesn't dream in vivid detail, or focus on the physical sensations very much.

That was about to change.

"Hypothetical: you're dreaming about me."

Nod.

"You're having an extremely sexy, erotic dream about me."

The immediacy of her nod gave me a lot of hope.

"You're jerking me off, and you're topless."

Nod.

"We're not in the hospital though--we're in the living room. You're stroking my cock, just like you have 34 to 37 times before. You're stroking my cock, and staring at it. You can see the veins, you can feel it throb in your hand. You know that I'm about to cum, and you're looking forward to it. You can't wait to feel me cum, feel my cock pulse in your hand, and watch me spurt."

Nod. Her breathing was slightly heavier, and she showed no sign of resistance. This dreams angle really seemed to be the way to go.

"You're topless, and you can feel the air conditioning on your nipples. Your nipples are hard, and your breasts are cold. Your hand can feel my warm, hard cock--it's so thick and excited. It's going to blow soon, you can feel it...and you want it to blow on your chest. You want me to cum on your chest so bad--you want to feel the contrast of my warm, salty semen on your cold, smooth chest.

"You want me to coat your breasts with my seed. You want to feel me cum on your tits, paint them, mark you as my property. You're so turned on by the idea--it's the sexiest, most erotic idea that you've ever had.

"You start talking dirty to me, telling me how much you want me to blow my load on your breasts, how wrong and sexy it would be. You lean forward, you're about to put your mouth on my cock when you feel my orgasm approaching.

"Leaning back, you feel me spurt onto your huge tits, and you love it. It's so hot that it makes you cum as well, without even touching yourself. We're just sitting there, cumming together, two siblings sharing an orgasm, two siblings getting each other off..."

She hasn't said anything, but the familiar flush was creeping up her neck.

"You wake up, and you realize that this is a dream you've had before. It's a dream you've been having every night, and you'll probably keep on having it. It's a sexy, erotic dream, and you wake up super turned on."

Nod. I take a deep breath--Marcie went for this next bit, but I've got no idea if Lucy will buy it.

"You lay back in bed, and play with yourself, thinking about the sexy dream you've just had..."

She was tempted. I know she was tempted, because she didn't say anything for a record time. Well, I wasn't timing, but it definitely felt like a record time--we just sat there in silence for ages, her breathing heavy, her skin flushed, her eyes staring wide and glassy at me.

Finally, she broke the tension, with a confused look, and a question.

"Wh...what time is it?"

Session 19:

I gave it a full week before checking in with Lucy again. In that time, I can tell you...I made good use of Marcie. I think she came over every day, and it was always the same--we'd get naked, I'd go down on her for a bit, she'd go down on me for a bit, and then I'd cum on her tits.

I honestly don't know why I was so obsessed with the idea...maybe because it was the closest to a genuinely dirty act that I'd actually managed to get. Sure, my sister thought she'd jerked me off a few dozen times, but she did that purely out of kindness. Her tits?

If she just wanted to hide my cum, there were plenty of other options. A pocket, her back, even a tissue. Suggesting that I cum on her tits...that's a sure sign of sexual interest if there ever was one.

Lucy waking up when she did hadn't been part of my plan, but it worked just fine. We'd been in the middle of a hypothetical about a recurring dream, and that was exactly what I wanted. I made sure to stay away from her room in the morning--I wanted to make sure she had total privacy, just in case a week full of dreams pushed her over the edge, and she wanted to relive them and play with herself.

I didn't even hypnotize her again--there was always the risk that she'd link me putting her under to the strange dreams she'd been having, and that would really put a crimp in my plans.

There was just one thing that I changed about my behaviour--I started approaching her every time I masturbated. Well, with Marcie around, I didn't really need to jerk off that often, so I just picked a couple of random times each day, and thanked her.

She was casual (if a little curt) in response, but more than once I saw a slight blush hit her ears when I thanked her.

I was getting close to something good. I knew it.

A week later, when I finally put her under again, I didn't dance around.

"Will you tell me what you've been dreaming about lately?"

"...no."

Jackpot.

Session A10:

"Hypothetical: you have a dream about me and Lucy having sex."

Shake.

"You have an erotic dream about me..."

Shake. Before I could even finish the sentence.

"You have an erotic dream about Lucy?"

Shake.

Stupid incorruptible mother.

Session 19:

"Okay," I started. I had a plan--there were some loose threads from previous sessions, and I was hoping that I could weave them into a perfect net. "So, hypothetical: ever since you jerked me off at the hospital, you've been having erotic dreams about me."

Nod. Thank goodness--the whole plan hinged on that.

"About six months after I leave the hospital, after you've talked me through jerking off a bunch of times...--"

"Five."

"Right, five. About six months after that, we go for a family vacation in a trailer park."

Nod. She'd mentioned a trailer park vacation a few times--in relation to discussing masturbation habits with me, if I recalled correctly, and so I figured that was as good a starting place as any.

"We're there for a super long time though--2 weeks, maybe more."

Nod.

"The whole time we're there, you keep having sex dreams about me--super erotic dreams, about jerking me off, or about me masturbating while you watch. In the dreams, you want me to cum on your tits. So, so much."

Nod. Access to her real-life subconscious was making this so, so much easier.

"But because we're in a trailer, you can't masturbate to release the tension. Mom's planned the activities in such a way that either we're all together, or it's just you and her."

Nod.

"Oh, and the public toilets there are really rank, so you can't use them or anything like that."

Nod. If the last trailer park was any indication, that was an utterly believable situation.

"After a few days, you notice that I'm really antsy. Now, you know that I normally jerk off a lot, and so you quickly work out what's bothering me."

Nod. Appeal to the ego--that's the key to my sister's mind.

"What do you say?"

"Hey," Lucy said, a soft smile in her voice. "I know that this must be hard for you--if you like, I can leave you alone for a bit, so you can...y'know. Take care of yourself."

"I tell you that I'd really appreciate it, and thank you."

Nod.

"Okay, Mom leaves, and it's just you and me in the trailer."

Nod.

"You go to leave, but the weather is woeful--if you were to go outside, you'd be soaking wet, cold, and miserable. What do you do?"

"I apologize, and tell you that I'm going to have to stay after all."

"I tell you that I really, really need this--that it's been so long that I feel like I'm going to burst."

Nod. I'm starting to suspect that my sister doesn't really know much how male masturbation works.
