The Erotic Mind-Control Story Archive

Later that night, my brother suggested a trip to the cinema, to check out the new Transformers film. To everyone’s surprise, Mom and Dad were able to come as well—they’re normally too busy to hang out with us, but by chance, the whole family had the night off. I sent my boyfriend a text, but he wasn’t able to make it.

Normally I’d just go the movies in whatever I was wearing around the house, but for some reason I was really drawn to a yellow skirt that’s been at the back of my closet forever. It’s a bit short, but since I was wearing some of my new, sexy panties, I figured it made sense to wear something that could potentially show them off.

And of course, if you’re wearing a short skirt, you have to pick a top to go with it. I hadn’t had a chance to wear my new push-up bra yet, so I picked a white button-up shirt that would show off some cleavage to go with it.

Mom raised one eyebrow when I met them at the door, but she didn’t say anything, and I don’t think Dad even noticed. My brother gave me a wink, which made my whole body go warm for a second, but then I realized how weird it was.

My brother was appreciating my body.

Although hell, why shouldn’t he? I was flaunting it. I was flaunting it…for him.

I mean, when I’m helping him out, that’s fine. I need to dress sexy if I’m ever going to help my brother cum, and as a sister, that’s what I’m here for. I mean, that’s what I signed on for.

But when we’re not…y’know, doing that, it felt kind of weird to have him ogle me.

We had to leave straight away, or we were going to be late, else I would have gone back upstairs and changed. As it was, I was tempted to skip the whole thing, but I guess I felt I was overreacting.

Sitting in the back with my brother, when he reached out to tussle my hair, I actually flinched, and I could instantly see the hurt in his eyes. My poor brother—here I was, freaking out without letting on what was happening—he hadn’t done anything wrong.

I felt so guilty, I immediately slid over to the middle seat, and leaned my head against my brother’s chest. He asked Mom and Dad to put some music on, and started slowly stroking my hair.

Stroke, stroke, stroke, stroke.

I looked around, stunned, when we arrived at the cinema. I must have totally zoned out for the whole car trip, I was so relaxed.

“What were you kids talking about back there?” Mom asked, and now it was my turn to raise one eyebrow. We hadn’t been talking about anything—I’d just been lying there, enjoying the feeling of my brother’s hand on my hair.

As Mom and Dad went to get the tickets, I wandered over to check out the movie posters. I noticed my brother was staring at me—with a grin, I made sure that no one else was around, and lifted my skirt up, giving him a cheeky flash of the thong panties I was wearing. After all, that’s why I was wearing them—the more I could turn my brother on, the higher the chances of making him cum.

And I needed to make my brother cum. I was going to do whatever it took.

We grabbed some popcorn and made our way into the cinema—my brother was on the end, then me, and then my parents, Mom next to me (so she could share our popcorn).

I’m not a massive fan of the Transformers films, but this one was pretty good—while we watched, my brother was idly stroking my hair. I love the way he does that—it’s so relaxing, and it always gets me so wet.

About half way through, he leaned over and whispered something in my ear.

“Hannah,” he said, “that girl—she’s so sexy.”

I nodded in agreement.

“She’s so hot…she gets me so hard.”

I blushed, and immediately started taking some mental notes. The way she wore her hair, the way she dressed—the more I could emulate her, the better my chances were of getting my brother off.

“Do you…do you think…”

My brother trailed off, and it took me a few seconds to realize what he was getting at. He’s shy—probably why he has the problem in the first place—but I quickly worked out what he was too nervous to ask.

I answered probably way faster than I should have. I was just so relaxed, so horny, and the idea of helping my brother in such a public place…with my parents right there…

I couldn’t resist.

“Shhh,” was my only reply, and as the giant robots battled before me, I tried to be as subtle as I could, reaching over and unzipping my brother’s pants, guiding his erection out into the cinema where anyone could see.

I was so turned on by the idea of what we were going to do—on one hand, I wanted to constantly check to make sure that Mom wasn’t watching, but I also knew that checking every few seconds was more likely to raise suspicion, and so I continued to stare ahead as I started slowly pumping my brother’s cock, up and down and up and down…

He leaned in close, still stroking my hair as I jerked him off in the cinema, my arm moving slowly, barely able to resist reaching down and touching myself. Every time the hot chick appeared on-screen, I could feel his cock swell slightly.

Sure, it was risky, but that just made it even more hot. Also, if this was what finally worked…if my brother could cum here, in a crowded cinema full of people, then I was sure he could cum anywhere.

I was helping my brother. Good sisters help their brothers. I was helping my brother cum—I was serving my purpose. I was helping my brother.

Stroke, stroke, stroke, stroke.

“Shhhh,” a man in the row behind us hissed, which surprised me. I was being so careful with my stroking, I knew I wasn’t making a noise. Occasionally I’d lick my hand, make sure it was as well-lubricated as possible, making sure that my brother got as much pleasure as he could from my administrations.

My purpose was to give him pleasure. I was dressed to give my brother pleasure. I loved helping my brother—it was so relaxing. I loved it when my brother saw my sexy lingerie. I loved dressing sexy for my brother.

As I stroked him, I was getting more and more turned on. My exhibitionistic streak was coming to the fore, as well as how relaxing it was, being SO comfortable with my brother. I mean, if you’re comfortable enough to jerk someone off in a crowded cinema…well, that’s pretty fucking sexy.

Up and down and up and down. Stroke, stroke, stroke, stroke.

I’m sexy. I love being sexy. I love helping my brother. Being sexy helps my brother. I love being sexy for my brother.

I blinked twice as a particularly loud explosion startled me out of my own thoughts. I mean, obviously I don’t like being sexy for my brother—it’s just a means to an end.

As the fight scene started to wind down, my attention was drawn back to the cock in my hand. It was such a lovely cock—I could practically see it in front of me.

Stroke, stroke, stroke, stroke.

To my delight, I could feel my brother’s hips start to jerk slightly, just like my boyfriend’s do when he’s about to get off. He grabbed the popcorn from me, and I held my breath for the next minute as his hips rose out of the chair, sporadically thrusting.

Had I done it? Had I finally managed to make him cum? Was…was my brother finally fixed?

And why did the thought make me so inexplicably sad?

When I couldn’t hold my breath any longer, I leaned over, trying to be as casual as I could.

“Did you cum?” I whispered, making sure that even in my excitement, I didn’t draw any attention to us.

“Of course not,” my brother said sadly.

“What?” I replied, in my surprise speaking far too loudly.

“Shhh,” the man behind us said again, and even Mom turned to us. Fortunately, the popcorn was blocking her view of my hand (which was still wrapped around my brother’s rapidly-deflating penis) and she quickly turned back to the movie.

“What?” I said, much more quietly this time, but when I turned to face my brother, he had such a look of sadness on his face that I could hardly bring myself to ask any more questions.

He quietly zipped his pants back up—just in time, too, because Mom almost immediately reached out and grabbed the popcorn.

“Hannah,” she said a few seconds later. “Does this taste weird to you?”

I tried some of the popcorn—there was a strangely familiar tang to it, but to my mind it improved the flavor.

“No,” I said, and she nodded, her eyes never leaving the screen.

The ride home was uneventful—I sat in the front with Dad listening to music, my brother and Mom sat in the back—but when we got home, I feigned tiredness and went straight to sleep.

As soon as my parents went to bed, I went straight across the hall into my brother’s room.

“Oh hey Hannah,” he said. “What’s up?”

I couldn’t help but look at him like he was an idiot.

“I want to…you know,” I said as I undid the buttons of my shirt. “Help. I felt like you got really close at the cinema—maybe tonight we can finally crack it.”

“Oh, thanks,” he said awkwardly, unable to stop himself from admiring how well my new bra emphasized my tits. “That’s really nice, but I’m not sure…”

“Please?” I asked, pouting as my skirt dropped to the floor. “I’d really appreciate it…”

“I dunno…” he replied with a heavy sigh, as I angled myself to show off as much of my body as possible. I was wearing nothing but lingerie now, my pert ass split by the strap of the thong. “I just…”

“What? What is it?”

“I can’t help but feel like I’m being so selfish.”

“Not at all!” I said, looking at him earnestly, tempted to punctuate my remark by giving my ass a hard spank. “You’ll be doing me a favor, I swear…”

I wasn’t lying. The car trip there, jerking him off during the movie—it had all been so relaxing, it had gotten me really worked up. I wanted nothing more than to watch my brother’s beautiful cock cum…

Not that my brother’s cock was…it was just because it was relaxing…

I stepped backwards, confused, but my head cleared as my brother started talking again.

“Honestly, it feels so one-sided. You come in here all the time and help me out—what do I do for you?”

“Don’t mention it,” I said sincerely. “Honestly—it’s no trouble. I really love helping you. It’s what I’m here for.”

Again, that didn’t sound quite right, but I was so turned on—so relaxed—that I was having trouble thinking.

“Thanks Hannah, but no…I don’t think I can accept your help. Not as long as…”

“As what?”

“…as it’s just you doing stuff for me.”

When I worked out what my brother was saying, my cheeks flushed.

“Oh!” I said, startled. “You mean…you want to…”

“No!” he said quickly, seeing the look of shock on my face. “No, Hannah, god no.”

Thank Christ. I love my brother, but the idea of him touching me like that…honestly, it made me sick. I was helping him with a condition, but if he were to touch me, that would be…that would be…

I hugged my brother in relief. I was so glad that no matter what else happened, we were first of all brother and sister. Even though he was fully-clothed, and I’d stripped down to my lingerie just to turn him on, there was nothing erotic about the hug. Not even when one of his hands ran up my back, and started softly stroking my hair.

Stroke. Stroke. Stroke. Stroke.

“Hannah, I could never do that to you…that would be wrong. But I can’t just let you be the one doing all the work, so I’m going to have to work this out by myself from now on.”

“No!” I exclaimed, my heart suddenly pounding. “No, you…you can’t!”

I couldn’t let my brother give up—not when we’d gotten so close! He couldn’t live the rest of his life sexually unfulfilled…that simply wasn’t fair. He needed my help—I was his sister, and it was my job to help him. It was why I existed…

“We can’t stop now,” I said, my brother’s hand on my hair calming me down, soothing me. Relaxing me…turning me on. “Surely there’s some way we can work this out…”

“I can’t just let you keep helping me, Hannah,” he said. “It wouldn’t be fair…”

Fair. Fair. Stroke, stroke. Up and down. Fair.

Without even thinking about it, I’d unzipped my brother’s pants and started stroking his cock. It was such a habit now—I just wanted to be a good sister. I just wanted to help my brother. It was all I wanted. He couldn’t make me stop now, when we were so close.

It wouldn’t be fair…

Fair. Up and down and up and down. Stroke, stroke, stroke.

I was staring at that beautiful cock of his, my hand barely able to wrap around it. I loved helping my brother—but it wasn’t fair.

Fair.

I was so horny…it felt like forever since I’d last been fucked, even though it had only been the previous day. I was so turned on, and there was a cock right there…but of course that was unthinkable. It was my brother’s cock.

Fair.

Without even thinking about it, I dropped down to my knees and took his cock in my mouth. I loved helping my brother. I loved my brother so much. I loved helping my brother. It wasn’t fair that he didn’t get to experience pleasure like the rest of us…it wasn’t fair.

Up and down and up and down. If I shut my eyes, I could imagine exactly what I looked like, my mouth wrapped around my brother’s cock, my head bobbing up and down. I considered reaching behind myself to let my boobs free, but I knew that he liked the sight of me in sexy lingerie, and that was all that mattered. His pleasure was all that mattered.

Up and down and up and down. Fair, fair, fair, fair.

I needed to help my brother—that much I was certain of. I needed to help my brother. It wasn’t fair that I could fuck my boyfriend and my boyfriend could fuck me and no one could fuck my brother.

Fuck my brother…

A twitch ran through my whole body at the idea. My brother had a girlfriend, about a year ago. Kelly, her name was—gorgeous, but boring as hell. The whole family had assumed my brother was dating her for her body—of course, if he couldn’t cum, there must have been more than that.

Up and down and up and down.

She must have been aware of his problem. And she’d stayed with him anyway…I couldn’t help but feel that we’d underestimated Kelly. All this time, we’d thought she was just a good fuck…

Fuck…

…when in fact, she must have really loved him, staying with him even though she couldn’t fuck my brother.

Fuck my brother. Fuck…

Up and down and up and down. Stroke, stroke. Fair…

Of course…

If we could find a way that I could help my brother and get off…

Obviously my brother could never touch me. That wouldn’t be appropriate, I told myself as I felt his pubes against my lips. Without even thinking about it, I’d started to deep-throat him, flexing my throat muscles as my tongue worked overtime, giving his shaft as much pleasure as I possibly could.

But what if I could get off while helping him? That would be…that would be…

That would be fair.

My body twitched at the thought. I was so horny, I was afraid I wasn’t thinking straight. I couldn’t seriously…I couldn’t suggest it to my brother. He’d think I was a pervert. He’d throw me out. He’d hate me forever for the idea.

But…

If he wore a condom…he wouldn’t really be touching me. I’d just be stimulating him like I was now. Except…with my pussy, instead of my mouth.

My mouth was stuffed full of my brother’s glorious cock as I bobbed up and down on it. I just wanted to help him…I just wanted to help my brother. But it wouldn’t be fair if it was a one-way street.

If he fucked me…we’d be helping each other. I’d be helping him with his problem, and he’d be helping me cum…

Up and down and up and down.

It wouldn’t even be fucking, not really. Like now, his cock in my mouth—it wasn’t really sex, it was just me helping him out. I was just stimulating him with my mouth. It would be the same thing…there wouldn’t be anything wrong with it, I’d just be stimulating him.

With my…

I’d be helping my brother. That’s all it would be.

I must have mentally debated it with myself for almost an hour—when I finally made up my mind, my jaw was completely exhausted, and I barely had any saliva left.

“Hear me out,” I slurred, “What if…what if we help each other?”

“Hannah…” my brother replied calmly, his eyes burning into mine. As soon as he said my name, I knew he was right: of course we couldn’t. That would be wrong. That would be…

Before I could finish my thought, his hand took over where my mouth had left off, and he started rhythmically stroking his cock. I couldn’t tear my eyes away from the sight. Stroke, stroke, stroke, stroke. Up and down and up and down.

Without even thinking about it, one of my hands went to my hair, and I began stroking it to the same pattern.

Stroke, stroke, stroke, stroke.

“Not…” I started, easily distracted by the beautifully relaxing rhythm. He really did have such a handsome cock.

I couldn’t help but wonder what it would feel like inside me.

“Not…touching,” I finally said. “You wouldn’t need to touch me…”

“Good,” he replied. “Because that’s out of the question.”

“But we could…do you have a condom?”

“Of course,” he said, and to his credit, didn’t even ask why I needed it. He crossed the room without ever stopping his hand from stroking his cock—stroke, stroke, stroke, stroke—and tossed me a condom from his bedside table.

Still on my knees, I crawled over to him, and slipped the condom around his cock.

“Please…” I said softly, lowering my panties, mesmerized by that beautiful cock of his. I was so horny—so turned on—I needed to get off, and if this was the only way I could help my brother, I was going to do it.

My brother looked shocked, but he seemed to see how serious I was, so without hesitation, he lifted me up, lay me back on the bed, and positioned himself at my entrance.

“Yesss…” I hissed, as my brother’s latex-clad cock split my pussy in two and slowly started sliding in. It felt so good—I’ve always enjoyed being fucked, but for some reason, my brother’s cock felt so much better than my boyfriend’s ever had. “Please…”

Shutting my eyes, I tried not to think too hard about the fact that I was fucking my brother.

Fucking my brother…

Instead, I just focused on individual sensations, sounds and smells. The slight grunt my brother made each time he filled me up the hilt, the feeling of fullness as his pubic hairs pressed against mine. How good it felt as his long strokes went in and out and in and out and in and out and in and out…

How I was helping him. I was just stimulating him with my pussy. I was just a wet hole for him to fuck, nothing more. I was helping my brother cum. There was nothing wrong with that.

And it felt so good…

Before long, I could feel my orgasm approaching. As he roughly thrust into me, my brother had started stroking my hair and muttering—I have no idea what he was saying, I figured it was just something to help him cum.

To help him cum…

The idea of this being what finally helped my brother cum was enough to tip me over the edge. The idea of my soaking wet pussy being what finally milked the cum out of his cock, got him past his mental block. The idea of fucking his little sister being what finally fixed him, what finally let him cum…

Everything went white as I came, thrusting my hips upward against my brother’s firm body, my cunt clenching and my toes tingling as I had a long, glorious orgasm, the best I’d ever had…

When it (eventually) finished, I was suddenly overcome with revulsion. What was I thinking? I’d just cheated on my boyfriend—I’d just slept with my brother.

“Oh god,” I said as I felt the bile begin to rise in my throat. I didn’t even stop to collect my panties—I just ran out of the room, praying that I wouldn’t encounter my parents in the hallway, needing to get back to my own room, needing to get away…

I’d just committed incest, and the worst of it?

My brother hadn’t even cum.
