“Yes, I’m serious! Now get it out while I’m still drunk enough to suck on it! Mom and Dad are out and you just told me that you’re in a huge dry spell. Please, little brother? I think it would be fun to mess around, don’t
“That’s right, baby brother, keep looking at my huge tits and you’ll stop crying soon. This always helps, doesn’t it? Here, I know we said we’d stop, but I think a break-up like this deserves an exception. Why don’t
I didn’t care if he was my big brother, because he was the only one who understood me. He didn’t mock me for the way I dressed or the music I listened to. He didn’t care that I was new at a lot of stuff that he was really experienced
“This isn’t a prank, little brother, I’m sick of doing nothing but tease you just because I can. I’ve grown up getting everything I want and now I’m going to get your cock. Don’t worry about your girlfriend, I won&rsquo
I was so excited to send a picture of my new look to my boyfriend, but in my excitement, I had sent it to my little brother instead. “wow sis” is all his response said. Everything changed after that.
“I’m just going to put that back in there, okay, little brother? Pretend you didn’t see that, okay?”But I saw the way his face changed. I noticed the way he started looking at me. I knew I should have put a stop to it, but I liked
“So….um, what do you think, little brother? That was way less awkward than I was expecting and I sorta, well, I sorta want to do it again. Do you think you could do what you did to start us off last time? I’ve never had that feel quite
“Let me put it this way, little brother. If you don’t stop pretending to be conflicted about this and get your cock between my tits in the next 20 seconds, then this is the last chance you’re ever going to get. I know you want to fuck
I should have known better. My little brother always had a thing for emo girls, but I didn’t think it would apply to his own sister, especially because I started doing it so much later than everybody else. It’s like he only just started notici
It was an automatic response now. My little brother walked in the door and I dropped to my knees. It had been out of my control for months now. I was starting to crave it.
“So. Um. That happened. Again?”My little brother’s cock twitched and I had my answer.
Text with picture:“I’d apologize for the mess, but u already knew ur little sister was a dirty girl ;)”
My little brother was doing so well. In just a few weeks I had trained him to go from a slobbering mess to an expert pussy licker. I was doing it as a favor to him at first, but now I was going to keep him around. His creepy lust for me was finally starti
I send my big brother one picture a day for him to jerk off to. That’s the deal. These days, after he’s done, he calls me from upstairs and tells me what he was picturing and how fast he came. I decided to give him mixed messages this time
“Are they good enough for you, little brother? You’re always bringing home such busty girls that I worry that I won’t be enough for you. You were always smarter than me in school and better at making friends, so won’t you please
“Look, I’m sorry, little brother, I know I basically used to blow you on command back in the day, but I think you need to move past this now. It was fun for what it was and I have no regrets, but I think we both knew it wasn’t going
“Seriously? Again? Didn’t I just jerk you off an hour ago? I know I said ‘anytime’ little brother, but I really didn’t expect you to be so, um, virile. Fine, get in here, but I really have to get some work done after this,
Regarding yesterday's post
“Yes, big brother, of course I’ll make your favorite cookies after I finish you off!”
“I’m sorry, little brother! I was just really horny and out with my friends. I only let him finger me in the bathroom, I promise! Please forgive me, you know I’m your big sister slut forever. You just make me so horny all the time, what&
I couldn’t believe the size of my little brother’s cock as he stripped for me. This really was going to be a good idea. I couldn’t tell where I wanted it first. By this point the guilt and confusion was somewhere far, far away.
Long text with picture:“I lied, big brother, you were right. I do want it again. I was just confused and embarrassed, but nobody has ever fucked me like you fucked me last week. I love the names you called me and the way you treated my body. I felt
“You’re breaking up with me, little brother? But why? I thought things were going so well. We were going to try anal tonight, remember? You were so excited. Something must have happened, what happened? Are you just freaking out with guilt?
It was so adorable to see my little brother get so worked up over just the sight of my body. It was weird, I had never thought of him sexually and I still kinda didn’t, but it was just too cute to see how horny he was. I think I’ve known for
“Are you ready, little brother? You said you were finally going to take charge today, so… I’m waiting…”
Text with picture:“I somehow got all wet, lil bro. bring me down some dry clothes? ;)”
Mmm, Li'l Brother Army...
“Hold on, little brother, jeez. I told you I’d be exactly 20 minutes and it hasn’t even been five. You’re lucky I agreed to this as it is! Do you know how fucked up this whole night has been? Now get the fuck back outside before
“That’s right, little brother, I found those stories you wrote about me. Can you tell the one with the tiny impractical bikini is my favorite? Why didn’t you tell me about your crush sooner? We could have been having a lot of fun. I
“I know I’m a lot older than you little brother and we never really got to connect as a result, but I want to be a good big sister and teach you things about the world. I notice the way you look at me when I come over and I want to make you
“Freeze!” My little brother yelled out, taking in a long, pointed look at my chest. He slowly walked up to me and lowered his hand just below my crotch so that I could sense his hand although it wasn’t touching me. “Don’t
It was the first time I faked it with my boyfriend. I had been secretly teaching my little brother how to fuck, but in doing so, I had made him my perfect lover. It dawned on me then, right as my boyfriend came, that my brother’s cock was the only
“God, big brother, why are you so nervous? Where’s all your big talk from yesterday? Remember all those things you said you were going to do to me? I hope you weren’t lying. We’ve talked about this for so long. I’m ready
One time. I had flashed my brother just one time. I was still paying for it. He had been emotionally blackmailing me for years, threatening to tell Mom and Dad all the dirt he had on me now that he had become obsessed with my body. I had info too, but
Sure, a lot of people wouldn’t understand. They wouldn’t think it was worth it. Why would I grant all of my pervy little brother’s requests just for some free rent? I guess I just don’t see the problem. I like sex, he never disresp
“And you promise you didn’t jerk off all week? Because if you held up your end of the deal, I’ll definitely hold up mine, little brother. This is going to be a fun weekend. Your first time is definitely going to be the fastest, so choose
“You’re doing a pretty bad job of hiding that boner, little brother. Why don’t you calm down and just have fun? Who cares if I get you hard? I can tell you’re a boob guy, and it doesn’t really matter that my body turns you
I had actually done it, I had actually convinced my little brother to jerk off for me. My suspicion was right. He was huge. I knew I should feel guilty for screwing him up just because of my lust, but at the moment, I didn’t care. I was too busy
“Yes, little brother, you heard me right. It’s your turn. You’ve been happy to cum down my throat, what, 100 times now? I think it’s time you learned how much fun it is to give head, not just receive it. Don’t worry, I’
I should have felt more guilty than I did. My little brother and I just had a talk a few weeks ago about how we had to stop messing around. About how I only went along with it because I loved him and felt sorry for him. I didn’t tell him that I&rsqu
“Well? Do you like them, little brother? You can’t just stare like that, I can’t tell if you hate them or not. Please say something, it took a lot of guts for me to show you like this.”
“Shhh, little brother, Mom and Dad might be asleep, but they’re just next door. I’m glad you like my big tits so much, but you have to keep quiet about it. You insisted you wanted a blowjob tonight, but it seems like you have other ideas
“Stop resisting, little brother. All those acting classes didn’t pay off, I know you want to touch me. What are you so scared of? I promise I know how to make you feel good. You just have to reach out- and touch. You don’t have to be
I practiced all night for my big plan.Everything was set up for my little brother, it was just a matter of whether or not I could actually seduce him. I hoped my instincts were right.
“Look! I got it just for you, big brother. Now will you let me practice blowjobs on you?”
“And you’re absolutely sure you can get me that much weed? It’s bad enough that I’m about to suck my little brother’s cock, but if you’re tricking me into it, I don’t know what I’ll do. Either way, you can&r
I was suspicious. My little brother had never cum so little before. Was he seeing somebody else?
I gave my little brother the look. He had been hanging out with me and my friends and he and I had been eye-fucking the whole night. We had agreed to wait until we got back home to mess around, but I was too horny. It was worth risking it. It was going
My little brother finally had the guts to start grabbing my hair, but he still wasn’t being nearly forceful enough. He was a lot of lessons away from me being done with him. Now that he had a girlfriend, it was my responsibility to teach him how
He was twenty minutes late again, but this time I could see the reason. He was making out with some girl right where I could see him. I couldn’t go out and yell at him because it would blow our cover. What would it look like if his little sister
