I even knocked beforehand, but this is still what I saw when I walked into my  big sister’s room. Our older sister had come home to visit, but I didn’t expect this. They didn’t even stop when I came in.
“Ohmygod! Little brother! What was in that drink? You’ve made my boobs grow so..um..so super big so fast! And why can’t I think of the word for super big?”
I was happy when my older sister and I would just make out, but she weaseled out my bimbo fantasy and I can’t believe how she responded! She even made the change so gradually. She always had big tits, but she started exposing them more and more.
My big sister came over to me and showed me this picture. “Why are you showing me this?” “I was hoping it would make you horny! Do, like, my tits look big enough?” “Er, sure, but why me?” “I dunno, I just want

Rough week
Busy
Little Brothers, Bad Timing
Here’s my confession, big brother. Ever since that day when I sucked you off at the beach, I can’t get it out of my mind. You’ve been avoiding me and I’ve been acting like I want to forget about it, but I loved feeling like your
“So what do you have planned for my slut training today, big brother?”
“Are you sure? Because I’ll do it. I’m your little sister slut, so if you want me to offer you my ass, I will.”
“Okay, if I come back in this room and you haven’t covered our little sister here in your jizz, there will be hell to pay. She’s 18 now, it’s time to turn her into a slut for her brother.”
“It’s fun undressing for you and everything, big brother, but when do I get to suck your dick?”
“This is so fucking boring. Mom and Dad told you to show your little sister a good time while they went into the city today. Why don’t we do something actually fun and go back to the hotel room and fuck?”
“Help me down, big brother. I really need your dick in my mouth.”

“I gotta say, little brother. I love that we’ve been hanging out again. You’d been so distant recently and I really missed you.”
As I lowered myself onto my little brother’s perfect cock, all of my fears and reservations went out the window. I was his sister whore now and it’s all I wanted to be.
It was obvious that my older sister had photoshopped the picture, but I thought it was cute that she tried so hard to impress me these days. As if receiving a daily morning blowjob wasn’t enough.
“That’s right, little brother! Just like that! I’ve taught you - oh! - I’ve taught you so fucking well. Eat your big sisters shaved pussy!”
E-mail with picture: “do u think my date 2nite will like this outfit?” My little sister is a bit stupid, so she’s probably actually just asking my opinion. Little does she know how crazy her pictures drive me. Especially when it’s
I kept telling my big sis that she would look awful with a fake tan, but she went in anyway. But to make me feel better, she sent me this picture.
My sister looked away casually after she took off her bikini top. Was she teasing me or coming on to me? Either way, I couldn’t stop admiring how great my big sister’s tits looked naked.
“Yes master,” my big sister said as she took off her panties, pretending to be under hypnosis. It had been a year and it was still the only way she would fuck me, but I’m not complaining. Who wouldn’t want a hot sister slut to
“Just this once, okay?” I can’t believe my kid brother grew up to be such a pervert.
With good looks and huge tits, my big sister always got her way. It used to really bug me, but then she turned her sights to me. Now I’m fine with her getting her way with me whenever Mom and Dad aren’t home.
It made no sense. I had never looked at my little sister sexually before. And I had seen the stupid Facebook pictures she posted hundreds of times. What was it about today that made me focus on her busty chest and uncontrollably spray my jizz all over
I love starting contests with my big sister. She wears low cut tops and I take out my hard dick. Whoever looks first goes down on the other.
I knew it was mean, but I started wearing tighter shirts and showing way more cleavage around my kid brother after discovering the smut stories he wrote about me. Â It was half out of anger for fucking with my mind and half because I loved seeing him
I had a little stage fright before entering her without a condom for the first time, but she was so sweet. She just massaged my balls and smiled at me. Nobody knows me better than my big sister.
“So what do you think now that they’re out of my tight t-shirt, little brother? Still don’t think they’re too big? What if I smother you in them?”
The moment she gave me this look, I knew things with my older sister would never be the same. It was the first time she actually considered my endless requests to see her topless as more than just a stupid joke. It’s when she knew I was serious.
She told me the plan a thousand times already, but I still felt nervous following through. She was in the position that was supposed to cue me. Why was it so hard to finally fuck my big sister when I had been fantasizing about it forever?
I felt bad that my big sister got so bored in between fuck sessions when our parents were away, but she was just so slutty and sexy that it sometimes took hours to be able to go again.
“Are you sure you lost your ring around here, little brother? I can’t find it anywhere.” “Keep looking, sis.”
“That was fun! And it tasted really good! But how about we have real fun next time? How do you feel about fucking your big sis in the ass?”
I adjusted myself on the couch beside my big sister and got lost in those huge boobs again. She seemed grossed out, but she agreed to cuddle with me. Hopefully she’ll feel differently when she feels just how big her little brother is.
My dumb kid sister has a YouTube channel full of pointless videos of her basically just making the duck face. I tell her they’re great though. I wouldn’t want to risk her taking them down and losing my jack off material!
I posed in all the positions that my horny little brother asked. What harm could it do, right? He’s just a boy obsessed with big boobs and I have big boobs. It’s not incest if he’s just looking, is it?

Goodnight!
My big sister and I hooked up for the first time last night and she sent me this picture this morning with a text: “Last night made me feel sexier than I have in a long time. So here’s me and my stupidly big boobs you love so much. See how
I knew it was a bad idea to bring my kid brother out that night. I had just broken up with my boyfriend and I was super-horny and on the rebound. Once I caught my brother looking at my big slutty rack, I gave him the eyes and I knew it was over. I needed
I take pictures all the time when I travel with my older sister. She thinks it’s to preserve the memories, but it’s actually because it’s the only time I can finally check out her big rack.
“Ready to play with my big titties, little brother?”
“What are you waiting for? Come fuck your horny little sister.”
“I don’t know why you wanted to do this photoshoot with me in my Halloween costume, little brother. You’re, like, half a year late!”
“This sweater was such a sweet birthday gift, little brother! I’ll wear it all the time!”
