It was just supposed to be fooling around. It was just supposed to be showing my little brother what a big natural set of tits felt like. So why are we fucking every chance we get? Why can’t I stop?
My big sister and I had this tradition since we were kids that we would go into the bathroom once every month and tell each other secrets. I loved the tradition so much, but it started to get difficult as we got older and there grew to be one secret that
I loved played Guitar Hero with my little brother. I always wore the most revealing tops and pretended not to notice when he would stare at my chest. Maybe it’s bad that I’d go this far for attention, but what harm could it do? It helps my
“Of course I’ll blow you right here, big brother. I did say ‘anywhere’, right? Don’t be so afraid to ask!”
I knew my little brother had been with a lot of girls, so I always made sure to try my best when he asked for favors from me. I didn’t want to be just another one of his sluts. I wanted to stand out.
“I want to give my boyfriend the best blowjob of his life tonight, little brother, so I’m going to practice on you again. You have to be completely honest and tell me how it feels, okay?”
“Here? You know I love your dick, little brother, but can’t you at least wait until we’re back in the car? You shouldn’t take me for granted. I’m not always going to be around to be your little cockslut.”
“Here’s your treat, little brother. Do even better next time I help you study and I might let you touch them. Remember, don’t tell Mom and Dad, okay?”
“Wait, you want me to what?! Big brother, I knew you requested that we share a room to get closer, but I didn’t know you meant like that!”
I knew my little brother was staring at my chest. I don’t know why I insisted we hang out all the time now knowing it was torture for him. I guess it was nice getting the attention without the expectation to do anything. Plus, he’s just a
My big brother still felt weird about seeing my face when he fed me his cock, so we worked something out. At first it made me sad, but now I feel hot knowing I’m his dirty glory hole sister slut.
“Oh shut up! She’s asleep and doesn’t know we’re related. When have you ever turned down a blowjob from your big sister before?”
What a bitch! We were all shopping for my little sister’s birthday and she texted me this from the dressing room! I had to sit down to hide my boner in front of my parents. I ignored it when my phone buzzed three more times.
Ever since my big sister found out about my crush, she would send me pictures like this just before she planned to fuck her boyfriend. I guess she liked knowing she could make two men in two different locations cum at the same time.
I’d suck my little brother’s cock anywhere at any time. He only has to ask.
“Tell me the real reason why you’re mad that I got this job, big brother. I promise to reward you for your honesty.”
“What’s the matter, little brother? Afraid it’ll feel really good? It’s only going to be a blowjob. Just relax and enjoy it.”
“No, big brother. You can only eat it with whipped cream on it. I told you, those are the rules.”
I was starting to get frustrated that every girl I slept with complained about my cock. Maybe it was my little sister, but I finally found a girl who could handle it.
“Please, big brother? I’m all grown up now. I was spying on you and your girlfriend all night last night. I want you to treat me that way. Don’t you think I’m pretty?”
“So take it out. Why are you getting nervous now? You’ve been complaining about your blue balls all week because of the way your girlfriend left you for her vacation, so why not let your big sister take care of you? I’ve seen you staring
I started complimenting my older sister’s tits a few months ago. At first she was creeped out, then she was annoyed, but then she started to expect and then crave it. When I stopped completely, she was desperate for the attention and cornered me
“Hard again already, little brother? Those two blowjobs obviously didn’t work. How about you fuck me this time? Maybe that’ll get you soft for at least a few hours.”
My little brother and I loved travelling together. We would pretend to be a couple and pick up another dick for me to suck for when he fucked me. It took him a while, but he finally believed me when I told him I wanted to be his busty sister slut.
“I’m so glad you let me fuck you now that I’m 18, big brother! Promise we can do it every day?”
“Why so shy, little brother? Got a boner for your bikini babe of a sister? ….oh.”
Text with picture: “u said u had a fantasy 2 fuck me after i spent hours getting ready. well 2nites the nite, big brother.”
“Ever since I sucked you off last week, I haven’t been able to get it out of my mind. I know I said I’m your big sister and we shouldn’t, so I’m sorry for the mixed messages, but get out that big dick now. I need my breakfast
My little brother must have been breaking the rules and fucking other girls. How else could he get so good so fast?
“I sucked your dick on the drive over here and you still want me? You’re so sweet, big brother. Go wait in the car, I’ll come take good care of you.”
No matter how much was my own saliva, I couldn’t miss a delicious drop of my big brother’s precum.
“That’s right, little brother, just like that. Good. Now I’m going to stick that big beautiful cock between these tits that you’re always staring at. I want to make you understand why you can’t stop looking. You’re
“I’m so glad I invited you!” My little sister said before throwing her arms around me and kissing me on the lips. It wasn’t until that moment when I realized why she wanted to pretend I wasn’t her brother around her new frien
“Come soap me up like you did when we were kids, little brother. But be gentle, I’m a lot more sensitive now.”
After months of snooping on my kid sister’s camera, I finally found what I was looking for. The guilt had stopped weeks ago and I didn’t hesitate to start jerking it right there in her room.
I did as he said and moved my hand down to rub my pussy. I thought I was in control of trying to make my little brother feel better, but I have no idea how it got this far. Maybe he’s not as innocent as I thought. Or maybe I secretly wanted this.
“It’s okay, little brother, she was no good for you anyway. I’ll take care of you. Big sister will make sure you stay happy.”
“Shut up and fuck me. I don’t care if you need to pick up your girlfriend. Your big sister is more important.”
“You gonna join us, big brother? It’s not quite too late yet!”
“Why don’t you take a seat over here and I’ll show you what was making the sounds coming from my room last night. My boyfriend likes it a lot, so I’m sure you will too, little brother.”
“That’s right, little brother, get that workout between my huge tits. You like using your own sister as your personal fucktoy, don’t you?”
“Yes, big brother, I told you it’s okay. It’s only a big deal if you make it a big deal. I told you that I understand. Your girlfriend dumped you, so you’ve been lonely and horny, and I can’t stand to see you like that. You
I sometimes made my kid sister take a new profile picture right before we fucked. It made it even easier to masturbate to later.
I didn’t mind driving my big sister wherever she wanted because she was always appropriately grateful.
“What d'you think, big brother? Am I good enough to be a model in one of your photoshoots?”
“Well if you really want to fuck me that badly, big brother, you’re going to have to do everything I say, okay? No promises that you’ll even get to touch me, but if you’re a good slave I’ll at least flash you. Deal?”
“I know you just wanted a massage, big brother, but now that it’s in my hand, I just wanna put it in my mouth. Is that weird?”
“Well that’s a good point, it would be convenient. You promise you won’t get weird and attached, little brother? Because I have been pretty hungry for cock these days, so if we can just keep this physical, then maybe you’re on
“You mean these, little brother? You always get distracted by my oversized tits? In your defense, I maybe started dressing differently when I noticed you staring all the time. It’s just too fun to tease you. But you’ve been a good sport
Fooling around had always been a chore to me before. Not that I didn’t enjoy it, but actually getting around to it took lots of effort. But not with my big brother. I was eager to please him all the time. I wanted to be his little sex toy.
“Shut up and stop trying to convince me it’s wrong. My boyfriend has been away for two weeks and he’s not coming back for another month and I desperately need a cock to suck. You’re the perfect choice, little brother. You’re
I could see my adorable little brother trying to cover his boner and pretend like he wasn’t checking me out. I asked him to do this photoshoot for me because I thought it would finally push him over the edge, but I suppose I’d still end up
Text with picture: “sry if this is weird, big brother, but im 18 now, so thought id get a guys opinion. think this looks hot?”
“Okay, you’re really starting to weird me out, little brother. I think you’re using the word ‘crush’ wrong.”
I love that this is usually all my big sister ever wore when we got the house all to ourselves. She didn’t hide the fact that just because we had done it that morning didn’t mean we weren’t going to continue to do it throughout the day.
