Let me be your busty sister (bustysister.tumblr.com)

I don’t remember when, or even how it started, but every night before bed, my older sister would come into my room and show off or play with her tits while I jerked off. We wouldn’t say anything and we wouldn’t touch each other, but
“It’s ‘cause of these, isn’t it, big brother? That’s why you’re being nice to me and taking me places. It’s what all the boys I know are doing. Do you want me to go down on you and swallow your load like I do
“Just be cool. Don’t expect this all the time. Mom and Dad are out and I happen to be really horny. This isn’t because you’re begging for it all the time, it’s just a coincidence. You shouldn’t get used to fucking your
“Don’t lose your balls now that we’re up here, little brother. Besides, what do you have to worry about? I’m the one who’s going to get her knees scraped up. You just get to have your dick sucked.”
It was awful. I would Skype with my little sister all the time now that I was away at college, and she started wearing riskier and riskier clothes during our calls. When I finally brought it up, she just gave me this shrug and acted like the question
“Ooo! Oh yes, that’s more like it. Delicate at first. When you start getting all the ladies off, don’t forget to thank your big sister for the lessons!”
“Thanks for the coffee, little brother. It takes me a while to stand up after a session like that, but it’s so worth it. You’ve improved so much.”
“I can’t believe how right you were, little brother! I’m so glad you convinced me to have a day in the park with you. I can feel all my school stress melting away.”
“So you actually like them, little brother? My last boyfriend said they were too big. He didn’t like having his dick completely lost in my cleavage, Want to find out if you feel the same way?”
My little brother and I finally worked out a way for me to get in my workout while still being his sister slut like I promised.
The Li'l Brother Army grows
“Nope! You’re not leaving until you go down on me, big brother. I must have given you over ten blowjobs this weekend, it’s only fair.”
“Back to the hotel room? Really? But we fooled around all last night, big brother, can’t we just enjoy the sun? Unless you’ve finally worked up the courage to try anal, let’s just wait until tonight.”
I promised myself I wouldn’t stare at my big sister this vacation, but she had always worn one piece bathing suits before. I was staring more than ever.
“No, that’s fine if you want to watch TV, little brother, I’m just hungry for cock. Mind if I suck you off while you watch?”
“Here you go, little brother. I thought it over some more and I don’t actually think it’d be so bad if I gave you a titfuck. I get that you’re just curious and have only dated flat girls. I’m sorry for freaking out at you
I was so nervous as my older sister who I had crushed on for ages was finally crawling toward me just like I’d always imagined. But I was so nervous that I couldn’t even get hard! I thought it was all over, but she just giggled and popped
I was a good little sister. I took my vitamins every day in exactly the way my brother told me to.
“Theeere’s my little brother’s big cock! Ready to explode in your sister’s mouth again?”
Text with picture: “at work and thinkin bout ur huge dick, big bro. hope u use this pic 2 get rdy 4 2nite!”
“Don’t look so sad, little brother! What if I do that thing with my mouth that made you really happy last week? Would that cheer you up?”
“See! Jiggly, big, and perky! Will you finally fuck your little sister now?”
“Take a good look, little brother. This is the best glance you’ll get at my big tits that you want so badly. Now go and jerk off in your room like a good boy.”
“C'mon little brother, titfucks and blowjobs can only go on for so long. We’re siblings, so my pussy is off limits, but it’s time you learned how to fuck your big sister in the ass.”
I always knew that my older sister wasn’t that bright, but I can’t believe that I convinced her that letting me massage her boobs would help with her back pain. She asks for a “treatment” daily. I wonder what else I can get away
My big sister used to tease me and boss me around all the time. But now that I’ve got her hooked on my dick, she’s finally learned her place.
“Are you sure you’re ready for this? All those rumors you’ve heard about your big sis being an even bigger slut are true. So why don’t you find out? I’m your busty big sister slut for the whole night. Your wish is my command.
I loved performing my cam show while my big brother hid off to the side and jacked off. It made me know he was proud of me. I was only sad that I couldn’t catch his load in my mouth or on my huge tits like I normally would.
“Why are you on the edge of the bed like that? I’m your big sister, there’s nothing to be scared of. I just want to cuddle like we used to. I know that I have boobs now and that you can’t stop looking at them, so I wanted to just
My little sister had become even more spoiled ever since her boobs got so big. She even used them to push me around. I know she was just being bitchy when she would bend over and sarcastically blow a kiss to me as a thank you for driving her places, but
I couldn’t believe it. I had lusted after my big sister for so long that I was almost paralyzed as she stroked my cock in just her bra and panties. “You’ve grown so big, little brother,” she said, “I used to get grossed out
It was so sweet that even after all these years, my little brother was still sometimes just happy with doing nothing but playing with my tits for hours on end.
“No, you can’t stick it in my pussy, little brother, that would be incest. But we can take care of each other in other ways like we have been all month. Or are you already bored of my mouth and tits?”
“There you are, little brother! I told you that today was the day I was going to let you fuck my big tits, but here you are hiding away! Are you nervous? I’ll walk you through it, okay? I promise you’ll enjoy it.”
“Think the cabbie will notice if I suck your dick back here?” My big sister said without waiting for an answer. It was like night and day with her. When we got drunk, she was an uncontrollable slut for my dick, but she wouldn’t even
My big sister was such a dork, always asking me to take silly pictures for her profile picture. I gladly did it, though, and she never seemed to notice all the extra time I took looking through the lens to, er, line up the shot.
“Okay fine! One more blowjob before bed, little brother, but only because you asked so nicely! This might be a record for you!”
“Aw, I love you too, little brother, but I don’t know why you had to sit me down in my room just to tell me that!”
My big brother is so jealous now that I work at Hooters, so I make sure to send him a pic every day I’m at work so that he knows I’m thinking about him. Lots of boys might be tipping me because of my cleavage now, but my sexy older brother
Leaving my little brother and his horse cock to go away to college was so difficult, but watching him jack it while I stripped for him over Skype made it a little easier.
Hiring my bimbo of a little sister was the best idea I ever had. I can’t believe she didn’t question all the duties I told her she was responsible for.
“Don’t touch that cock, little brother! You know what will happen if you do. So if you want me to continue taking care of you, you just have to enjoy the show and wait until I slip it into one of my slutty holes.”
I made sure to start every day with a nice big load of cum from my older brother. He told me it would help me grow up to be healthy and smart, so I’m lucky that it tastes so good!
At only 18, my little brother was almost ten years younger than me, but that’s what I found so hot. He was so eager and willing to do whatever I said and although it only took him a few seconds to cum, there was always so much and it was always
“Time to wake up, little brother. Big sister is super horny.”
I could always tell when the change happened from “diligent big sister performing a blowjob” to “busty sister slut craving cum” and it was so hot.
“That’s good, now you’re learning. It’s always a good idea to feel up your busty big sister while she jerks you off. You might have to let go when I put this nice hard cock in my mouth, though.”
Out for the day...
“Thanks for the ride to my boyfriend’s house, big brother. Come to the back seat and I’ll give you your usual blowjob as payment. It’ll be so exciting to kiss my boyfriend after swallowing my brother’s big load!”
“Aren’t you done your homework yet, little brother? You said you’d come upstairs and fuck me ‘in 15 minutes’ an hour ago!”
“Are you starting without me again, little brother? You know that I’m the only one who’s supposed to touch your cock, and that includes you!”
“Okay, I’m on my knees, so what’s next, big brother?”
