The Man of the House

Chapter 70

“Brother…” Kristy’s hot breath brushed against my face.

Kristy’s face was bright red, and despite the fact, her hand was holding my cock, she wasn’t letting go of it. Normally, you’d pull back instantly like you were just burned if you found your hand where it wasn’t supposed to be, right? Then again, I could have just let go of her too, but then she would fall and that woman waiting outside of our shower would be bound to hear what was going on in here and grow suspicious.

We remained frozen like that for several moments, neither of us quite able to move from such a position. Then, her hand slowly began to move. I thought her hand was going to leave my cock, so I lifted her back up, but then her hand started to move up and down, stroking it. My eyes started to widen as Kristy started to stroke my cock with gentle movements.

“Wh-what are you doing?” I whispered in surprise.

“It feels good, doesn’t it?” She panted, a flash of guilt on her face, even though her hand continued to move.

“How can that be?” I tried to deny it.

“You’re hard, aren’t you?”

I opened my mouth, but there was nothing I could say. She had caught me there. I was completely erect. She never would have grabbed my cock in the first place if it wasn’t already half-cocked. Just touching it was enough to have it spring into motion. She had accidentally grabbed my cock, but feeling it was hard, she knew I was aroused, and when pushed between the decision of stopping or continuing forward, her horny brain chose to march forward. I respected that. No, wait… we were still in a shower with other girls sitting outside.

“Sister…” I breathed out heavily, not able to bring myself to pull her hand away.

If I rejected her here, would I just be embarrassing her? I know it seemed hypocritical hesitating with her, but Mackenzie, Dawn, and London were my older sisters. If anything, they were responsible for me. That’s why I had acted so recklessly and selfishly with them. No one would treat me like a predator when I was younger. Logic from my old world was hard to drop.

Kristy was only a year younger than me, but she was two years younger than Mackenzie. That was still the youngest woman I had done anything with. I tried to flip things in my mind. What would it be like if an older sister made advances on her younger brother? Probably a lot like what my sisters had done to me, right?

Kristy put her free hand on my shoulder. “It’s okay, Noah. I’ll take responsibility. I’ll show you how to be a man, okay?”

I stared in shock as she grew bolder with her hand movements, pushing herself to me with a slightly lewd grin on her face. As I was debating and arguing in my mind what to do, it looked like indecision to Kristy. My hesitation had only aroused her further. I realized it was like a girl who was just on the cusp of submitting sexually. It inflamed the predator in a guy and made him more likely to want to take advantage. I had inadvertently stimulated my sister’s desire to conquer me!

I had been seeing things as me taking advantage of a younger sibling, but girls in this world were horny little monsters. Boys desired sex from a young age, and they’d even chase an older woman to get it. I was the perfect proof of that! Somehow, the power dynamic between my sister and I flipped, and she was grabbing me like she wanted to eat me up. She grew more aggressive, stroking my cock with long wet strokes as she pulled my head into her chest.

Were all of my sisters secret perverts? Were all women perverts? Would they all take advantage of their poor brother if they had the chance? I was just asking for the sake of my sanity, I was pretty sure I already knew the answer.

“W-we can’t…” I hissed from her tits, realizing she had tried to shove my face there so I couldn’t argue.

I had meant that there were people outside and they’d totally hear, but as soon as I said it, it sounded bad in my ears. Yup. That was the wrong thing to say. That only made her eyes flash more excitedly. She grabbed a chunk of my hair and looked into my eyes.

“It’s okay, you can cum for me.” She purred. “Just relax, big brother.”

Well, you couldn’t be indecisive when the decision was made for you. In her youthful mind, I was her virgin brother who was budding her sexuality. If she knew I had already slept with all of our older sisters and even played with a few adults, I wondered what expression she’d make. She probably thought I didn’t even masturbate. Thinking about it, as I let her push my face back in her breast, a dark grin formed on my face.

“I’m feeling hot, sister… my head is woozy and I feel weird. What are you doing?” I asked such a cringy line.

If any guy acted that way in my world, they’d lose their man card, but for a woman of this world, being pure and innocent was like her kryptonite. I had learned that much with my other sisters. However, I had always allowed my hormones to take over and I had acted aggressively with them. When it came to this situation, I still had enough of my mind that I could hold back and act like an innocent lamb.

“It’s okay… have you ever gotten hard before?” She asked.

I shook my head, trying my hardest not to burst out laughing as her face grew even more perverted. It was a face that if a guy wore while looking at a girl, she’d respond with ‘gross’. However, I didn’t grow up in this world and this was my cute little sister, so while that expression was funny, it was also extremely cute. Now, I was holding back from just taking her right there.

“It’s probably because you like my feminine body.” She whispered in my ear. “It’s perfectly natural. When that happens, I can take care of it just like this.”

I shook pressing my face in her chest as I suppressed a laugh. She’s my younger sister, but she seems to be trying to teach me about the birds and the bees. I was certain she knew nothing about them herself. It was the blind leading the blind. No, it was the blind leading a person with perfect vision. I was a head taller than her, but she was acting like a total dominant, her free hand even reached around and grabbed my butt. She took my shaking as shuddering in pleasure, and only grew more excited.

My laughter continued until suddenly, her fingers started working their way into the crack of my butt. My eyebrows shot up. Her finger pushed against my butthole.

“H-hey…” I cried out, no longer teasing her.

“It’s okay, brother, you’ll really like this.” She said.

“That’s…”

There wasn’t a lot of room, and if I made a commotion trying to resist, we’d be found out. Furthermore, she was still my little sister, and she was using me to explore her sexuality. Although she was acting confidently, I could feel her hand shaking slightly. This was far out of her element, no matter how much she wanted to take advantage of me. I decided to bear with it, and let her play with my ass. I had done similar to the girls before, but so far, a girl had never done it to me. It felt weird, but I didn’t hate it. That was when she slipped her thumb into my ass. She didn’t have nails or anything, so it popped in easily

As my mouth opened to cry out, she kissed me, sticking her tongue down my throat to cut the sound out. As she kissed me, her thumb pushed deeper into my butt. I had stuck bigger things into a girl’s butt, yet I never wanted my ass to have something in it. When she broke her kiss, her thumb was already up there. I glared at her, and for the first time, she blushed.

“Do you hate it?” She asked innocently.

Even though she was asking, her thumb was wiggling around. It didn’t hurt or anything. Then, she brushed my prostate, and I felt my balls tighten slightly.

“Sh-shit…”

She blushed further. “We’re in the shower, so it’s fine…”

“No, rub that again.” I panted.

“Ah? Here?”

Her thumb began to finger my prostate. It felt strange, but also really interesting. It almost seemed to make her grip on my cock more sensitive. As it was, I was so worried about where we were that I hadn’t gotten too worked up over her hand motions. She was new at it and was mostly just pumping it without any tricks. But as her thumb stroked my prostate, it felt considerably better.

I clenched my teeth, and then sucked on her tit. She let out a small cry as I engulfed her tit in my mouth. I did it so I didn’t cry out myself, as the feeling was really exciting.

“B-brother… yes, eat my tit… let me finish you off.” She purred.

She stroked my prostate with her thumb and my cock with her other hand. She even used her fingers from the hand with the thumb in my ass to stroke my balls. I had never experienced something like this before. Leave it to our youth to teach us new and exciting things. Well, we weren’t that different in age. I was teasing her for being a virgin, but it turned out she knew some things I didn’t.

I sucked excitedly on her tits, my tongue licking the nipple as I suck it in and out of my mouth. Her breathing had grown heavier, but the feeling of the double treatment was as much as I could handle.

“Mmm! Mmmm!” I moaned into her chest.

My cock exploded out, and cum shot onto my sister’s stomach. Since the warm shower was still raining down on us, it took a few streams until she looked down and saw me cumming. She laughed softly, her stroking slow as she pulled her thumb out of my butt. I felt both relieved and satisfied. I finally spit her boob out, a bit red from my attacks. She smiled at me happily.

“Did you like it?” She asked, licking her fingers that had been on my cock.

“I…”

“What are you doing in there? Are you schlicking off?” That woman who had been waiting outside suddenly said.

It turned out we had been louder than we had thought. The other two girls had stopped their showers, and although ours still made noise, it wasn’t enough to cover up all the muffled noises and wet splashing sounds. It sounded extremely suspicious.

Kristy’s face turned red as she realized that because of her perverted desire to take advantage of her big brother, she had only made the situation even worse. She switched places with me and immediately poked her head out the curtain, doing it in a way that would cover up everything but her head.

“Don’t be ridiculous! I’m not doing anything like that!”

“Are you blushing? That’s gross! You really were doing something like that!”

“I’m not! Anyone would blush when accused of something they weren’t doing! Besides, the shower is hot! Why don’t you mind your own business? Why is my shower so damn important to you anyway? You’re the one sitting here listening to someone else shower. Who’s the creep here?”

As she argued with the other girl, from my side she was bent over with her ass wagging at me. I could see a vertical smile and a hint of her butthole. She had decided to just shove her finger in my ass. I was looking for a bit of payback, and she was wagging it in my face. Better yet, my cock was still erect. Stroking my prostate had caused me to cum, but I hadn’t lost my erection afterward. I was ready for another round.

I had let her be in charge. Now, it was my turn!
