“I want your dick inside me so bad.” Mackenzie begged.
Although this wasn’t the first Mackenzie and I had sex, the atmosphere was completely different now. She had previously been holding herself back, perhaps thinking that as long as she kept herself emotionally distant and we only had sex for physical satisfaction, that she wouldn’t end up feeling things that she did for her brother. It seemed like after giving in to her desires and finally admitting that she was just a giant pervert who lusted over her younger brother, her restraints had disappeared completely.
She started speaking a lot more vulgarly to me, her eyes filled with a thirsty longingness. It was like she wanted to have every part of me, and nothing was enough. After I nearly choked her with my cock, she cleaned up and came out ready for more. This time, she decided to let me take control. Well, I always took control, but this time she surrendered to me. That was to say she lay back on the bed and then spread open her pussy with her fingers while saying such dirty words. If my cock wasn’t already hard, just the sight of my sister like that was enough.
I wanted to take pictures so that they would last longer, but I didn’t want the possibility of them leaking out and becoming a problem. I didn’t mind if my body was seen, but I would be furious if anyone else saw my sister in that position. Maybe that was a bit petty of me, but just like Mackenzie, I had come to terms with my nature when it came to my sexy sister.
I got onto the bed and moved between her legs. She looked up at me excitedly, ready to get pierced by her brother’s cock. I lined the head of my cock up against her wet, waiting lips. I was too excited though, and when I pushed, it slid up, sliding up along her slit.
“Ahhh… b-brother… teasing me.”
Seeing her gasping and looking at me with frustration, my darker and more teasing side was stoked. I started to playfully rub my head against her clit, teasing her without penetration. I watched as my sister moaned, biting her lips in aggravation over unsatisfied lust.
I had already gotten off on her throat, so I was much more in control at the moment. However, my cute little sister had been teased and teased again, and still, she hadn’t gotten off. Now, her horniness had reached a limit, yet rather than fulfilling her desires, I only teased her a bit more. She was going crazy, but the looks and whimpers coming from her were far too interesting. After she acted so domineering, wasn’t she just a helpless slut? Well, I wouldn’t think such disparaging things about my sister for real, but for this moment and time, my sister was just my little sex toy.
“Please, stick it in… I need it so bad.” She moaned in a voice that sounded pained.
She was rocking her hips, trying to force my dick into her. She wanted to be filled so badly it hurt. I realized that if I waited too much longer, she might start getting angry at me, so I decided it was finally time to give her the release she wanted. Reaching out and grabbing her hips, I shoved myself inside my sister’s pussy. Her back instantly arched, and I could feel her pussy grabbing my cock and sucking it in. Was my sister already cumming just with that?
“Ahhhn…. Ahhhh… fuuuuuck!” She moaned, her face scrunched up in a cute expression as her body orgasmed wildly.
Feeling quite happy about bringing her to orgasm so easily, I threw myself on top of my sister and started to thrust my hips. Before she could finish one orgasm, I was jackhammering her into another. Her eyes rolled back and her body twisted under me as she was driven to sexual heights again. Her hands reached out and grabbed my arms firmly, but soon her nails started to dig in as she reached yet another climax. My sister was horny since she came twice in only a few minutes with barely any action.
“Oh… shit… fuck…” she moaned out, speaking lewdly and feely as I gave her the full length of my dick.
Her pussy was so wet and wanting that it gobbled my dick down to the balls without any resistance. I could feel a wet sucking sound whenever I pulled out, and a lewd squishing sound whenever I plunged myself back in. She was extremely juicy, and her horny scent quickly filled the room as she went crazy having orgasm after orgasm.
Her nails were scratching my back, and she was moaning with her legs bent and trying to bring me deeper and deeper inside her.
“Noah… fuck… your big dick is filling me up. I fucking love it.” She spoke dirty words in a barely coherent manner. “Give it to me, give it to me. Crush my womb. I fucking love it.”
With her words as encouragement, I picked up the pace, slamming down into her pussy like my dick was trying to reach some treasure buried within and the next thrust was all I had to obtain wealth. Mackenzie was moaning so loudly that there was absolutely no way that she couldn’t be heard.
“Fuck! Fuck! Fuck! Yeah, right there! Fuck!” She cried out as she came once again on my cock.
She was humping my cock about as much as I was thrusting into her. Even if I sat there and did nothing, she’d be getting off on my dick all the same. As she wildly banged me, I expected to lose my load in an instant, but I found since coming to this world I was starting to build up my stamina. All of these horny girls who wanted to fuck over and over again, I had to keep going, right? Of course, the main reason is that I had already finished once, so I had a bit more stamina for the second go.
“Ahhh! Ahhh! Yes! Yes!” Mackenzie came again while using my dick to her fullest.
She finally let her hips fall back down. Since I had been letting her do the work, she was panting now. A thin layer of sweat covered her face and chest, giving her skin a shine that made her appear just a bit prettier. She smiled up at me, but then her smile faltered slightly.
“You didn’t cum.”
“Geh… uh… I did…”
“Tsk… don’t be one of those guys who fake it.” She glared at me.
I stiffened slightly and then laughed. “Ah… sorry. I guess I didn’t cum, but I already came earlier, so…”
“No, that’s not good enough!” She pouted. “I want brother to cum inside me. I recently got on the pill, so it’s not a problem.”
“When did you do that?”
She looked away and scratched her cheek. “Ah… after our first time.”
“I-is my pussy not tight enough?” She asked nervously.
“What? How can that be?”
Mackenzie had gotten lost in sex, and even orgasmed several times until she exhausted herself. However, because I didn’t lose my nut, something I was a bit proud of, she took a hit to her mental health. In this world, women made men cum, and if they couldn’t, there was something wrong with them. If my sister didn’t cum, she’d be blaming herself, and if I didn’t cum, she also blamed herself! It was a weird way to think but in a kind of cute way. It made her seem even more adorable.
I could explain I just needed to go longer, especially after already cumming a mind-blowing orgasm earlier, but how could she accept that? While I was thinking about how I could tease her more, Mackenzie mumbled something that I completely missed.
“I’m sorry, what was that?”
Her cheeks turned red. “I said, do you want to stick it… in my ass. You put it in one time, but…”
“You want me to stick it in your ass.”
“I-I said I had three holes,” She responded. “You’ve never cum in my ass before. Can we try that?”
Her voice had a slightly perverted sound to it like she wanted it but didn’t want to seem like she wanted it. Usually, it was a guy begging to put it in, but in this world, it seemed like girls wanted their asses violated.
I had tasted anal more fully now, but I still didn’t have that much experience. The girls usually didn’t ask, and I didn’t feel comfortable asking on my side. As much sex as I had, it had only been a few weeks since my sex life had picked up. I was usually more interested in pussy anyway. Girls were typically a bit less clean in this world, so I didn’t want to put myself into situations that may be gross. Mackenzie kept herself clean though, so I didn’t worry about it. I still made her go to the bathroom and clean herself again just in case.
When she came back, she had a small vial which she handed me. I looked down at it in surprise. It was lubricant! I didn’t know where she had gotten it, but she had certainly come prepared. She got on the pill, and now she’s lugging around lubricant too. My sister had seriously been planning this for a while. She got on the bed on all fours, hiking her butt in the air. She then reached behind herself and spread her cheeks.
“Stick it in,” She instructed encouragingly.
I hastily opened the bottle and then put some lube on my hand. I didn’t quite know what to do with the lubricant. Most girls were so horny that they didn’t need anything like this. As for the main anal experience I did have, it was in the shower and I was intentionally being rough. I took the lubricant in my hand and then wiped it up her crack and across her asshole. She let out a cute noise, but nothing else. She still waited expectantly, showing me her backside like this.
Licking my lips, I squirted some more lube onto my palm, and this time I spread it over my cock, stroking it several times until it was covered in clear stuff. Her tight ass, slightly darker than the skin of her smooth ass, reflected light and appeared slightly shiny. My dick looked shiny too, thanks to the lubricant.
I moved up and pushed the head of my cock against her asshole. Her butthole pressed in slightly as my dick pushed against the surface. She let out a long breath like she was preparing herself. I pushed my hips forward, and the head of my cock popped inside. The outer rim of her ass seemed to slide around and then cling to the head of my cock, like it was some kind of thin mouth. Inside, I couldn’t feel any pressure, but just a thick warmth. I started to push deeper inside her.
Compared to my time with Jasmine or even my first time with Mackenzie, I was savoring the feeling. I pushed my cock in about halfway. I could hear Mackenzie breathing hard.
“Are you in?” She asked with a strained voice.
“About halfway…” I admitted honestly.
“Shit, I feel like you’re breaking my ass in half,” She said.
“Should I pull out?”
“N-no… I can take it.” She responded with a cry. “Please, take my ass all you want.”
Since my sister asked nicely, I decided I would do just that. I reached out and grabbed her ass, squeezing that round, soft tissue in my hands. Mackenzie’s ass was the best. Now, I was getting to ride it from behind. I shoved my dick in the rest of the way, allowing my dick to explore the deep recesses of her buttocks. Her hands tightened on the sheet as she let out a muffled sound into the bed. I guessed it was time for round three.
