Let me be your busty sister (bustysister.tumblr.com)
submit your pics
It had been almost two years since the last time, but for some reason I didn’t hesitate for a second when my little brother asked me for a titfuck. I dropped to my knees without a conflicting thought and neither of us brought up our promise that
I was still pretending not to love it when my big brother nailed me to my bed. I told him that I was only doing it because he was my brother, and I loved him enough to let him indulge in his perverted fantasies. I resented him for doing it anyway, it
“If you haven’t guessed already, little brother, I’ve decided to reconsider your offer.”
“Are you sure you have to go, big brother? Is your guilt really that much bigger than my tits?”
My boyfriend was ignoring me again, so I decided to finally give in to my pervy little brother’s requests to send him pictures. I had to get attention from somewhere.
“Oh yeah, sure thing, little brother. You say this is the last time, but that’s only because you just came. Even with me saying this out loud to you, your pride can only last so long against  your lust.”
I'm feeling selfish
For months when my big brother and I started fooling around, I was always in charge. I still remember the day I hesitated when he tried to take control, and that’s when the power shifted and never returned.
“Um, I think it’s a little late to start feeling guilty now, little brother. I think it would be a lot more fun to just go again.”
Another night out and another picture to send to my big brother later. I knew he loved jerking off to pictures of me before I would spend the night hooking up with guys, but I just wanted him to come home soon so I could spend the night with him again.
“I’m so excited that we get the whole evening to ourselves, little brother! Where do you want to start?”
“That’s a good boy, you know the rules. Keep your mouth shut when big sis is horny.”
I used to hate when my little brother would make me call my boyfriend right before fooling around, but now it was something of a ritual.
It was hard to be sexy for the video when my brother kept smiling at me. I don’t know why he insisted that we fool around after the video, it was too distracting. Although it was hot knowing that other guys would be jacking off to me not knowing
I was doing a damn good job holding up my end of the bargain. I hoped my pervert of a younger brother’s word was as solid as his - admittedly delicious - cock.
“Hey, let’s sneak off to the bathroom, little brother, okay? I’m sure nobody will notice. Just a quickie.”
“Why are you sitting back here by yourself, little brother? Everybody at the BBQ is wondering where you are. Something on your mind?”
I was worried that my little brother would stop lusting after me after he saw me topless, but he wasn’t like those other boys just in it for the chase. It’s so great having such an eager horny boy across the hall from me.
“That’s right, big brother, I can feel that big bare cock in my tight little pussy. You’re such a pervert for letting your slutty little sister come on to you like this. I want you to cum without warning me, okay? I want to be everything
I told my sexy big brothers that I was ready to handle them both, but I struggled the whole time and I could tell they were frustrated. I really hope they give me another chance.
I don’t know why my little brother insisted on roleplaying. It never took more than three minutes for his cute face to be latched onto my pussy, but I’m not complaining.
“I can’t believe we just did that, little brother, can you believe we just did that? …Want to do it again?”
“That’s right, little brother, today you finally get to eat my pussy like you’ve always been asking about. I’m going to make you suffocate in my juices the way you choke me on that big cock of yours. You’d better be ready.&rd
My big brother seemed too nervous. He made me hot because of the way he would tease me, so I wanted him to be relentless with me, not gentle like my boyfriend. I glared at him and he seemed to understand. I wanted my hot big brother to fuck me. I wanted
“Hey, it’s okay, one day we’ll run away and get a place of our own, okay, big brother? Until then we just need to keep sneaking around. Are you really moping because you’re about to get a blowjob? Looks like you’re forgetting
“Please? Just one more time, little brother? Doesn’t it feel good?”
I went to my little brother for clothing and makeup tips. Y'know, a man’s opinion that I could trust. The thing is, he had me start to send him daily photos for his approval, and he’s been harder to please these days. I know what I’m
It was really bad, but I had found a way to make my dim-witted big brother do anything I wanted.
“You were SO sweet on our date today, big brother. I want to make you feel as good as you made me feel all day, okay? Are you sure this won’t be weird for you?”
I didn’t know that my big sister was spoiling me with her enthusiasm and dirty talk. She fooled me into thinking that she was a slave to my dick when really she was turning me into her slave. I realized my cock belonged to her.
“Oh yeah, sure, little brother! You can ask me for stuff like this at any time, okay? This is how siblings take care of each other. And don’t worry about getting me a pillow, I’m used to kneeling without one.”
Big brother almost forgot to feed me today, I’m so glad I reminded him.
“Pull over, pleeeeaase? It’s been three hours since you last took care of me. The deal was that I’d be your busty big sister slut at the cottage if you were my sissy little brother slave on the drive up. You have to pull your weight
My little brother and I played this game. I would stand in public and look blankly forward until men got less inhibited with their glances. My brother would watch from a distance and get hard as all the men looked at his busty sister. The idea would be
I will be the perfect bimbo for my little brother. I will make it so he will stop looking elsewhere for a girl. I will give him everything he wants. My desire will be to fulfill his desire.
“I see you like them, little brother, but do you know what to do with them? Or will I have to show you?”
“Are you getting second thoughts, big brother? It’s up to you, but this is the only time I’ll do this. There’s no way I’ll make a bet like this again.”
Only my baby brother knows how to make me feel better after I’ve had a fight with my boyfriend.
“Now be honest, little brother. Have you truly never wondered what it’s like to get a blowjob from me? Or to stick that big hard cock between my oversized tits or watch them as they sway under me while you fuck me from behind? Huh, little
“Oh you’re so cute when you’re surprised! I’ve known for months, it just took me a while to come around to the idea. So c'mon, let’s see my little brother’s hard cock.”
She had been saying “but this is the last time” for almost two months now and we both knew the new meaning it had taken on. My big sister smiled warmly before dropping to her knees without a pillow to kneel on.
Text with picture: “Here you go, creep. Don’t know y u need a pic of ur lil sis on ur phone so bad.”
“I’m so glad you asked me to help you with your confidence, big brother, I know exactly what to do.”
My big sister was laughing at my jokes in ways she never had before, and I think I even caught her checking me out. Could I really allow myself to believe that my deepest fantasy was coming true?
“I’m telling you, we have amazing soundproofing in our house, little brother. I bring boys in here all the time and you and Mom and Dad never hear how loud I am. I seriously think it's so cute that you’ve been jacking off to pictures
Yet another text from my sister:“will THIS convince you? cmon into my room already! i wanna teach my little brother how to fuck!”
Dear diary, he let me suck on it again today. It tasted so fucking good when he shot his hot load in my mouth. If I didn’t love the feeling of swallowing it so much, I might have kept it in there. My big brother is so good to me, diary. I hope I&rsq
“C'mon, big brother. For old time’s sake.”
“Hey now, little brother, the least you could do is clean up in here if you keep expecting me to blow you every time you get the urge.”
“And you can finish up right. In. Here. Would that make up for the fact that I didn’t buy you a Christmas present this year, big brother?”
