“C'mon, little brother, don’t be shy! We’ve been planning this for weeks. You finally get to fuck - how did you put it? - your sexy sister and her huge slutty boobs? *giggle* it’s so cute when you try to talk dirty. I’m going
I hope I’m showing enough cleavage. I really want my big brother to jerk off to this after I “accidentally” send it to him. This is my way of finding out if his glances at my chest are just him being a boy, or if it’s something
Is that the door? I hope it’s finally my sexy little brother. I’ve been lying on the floor all day like a good slut. Like he asked me to. I hope I get rewarded with his amazing cock. I’d do anything for that dick.
“You promise you like them, big brother? Will you stick your dick between them like in all that porn you watched while I spied on you?”
I couldn’t believe it as my big sister walked in with a glazed look in her eyes. My hypnotic suggestions actually worked! “It’s 8 o'clock. Time to use your sister whore. How do you want me, master?” (Click here to read my position
I loved that my big brother and I finally admitted our lust for each other, but I hated that it was over Skype when he was across the country for college. I couldn’t wait to feel that big dick fill me up.
“See little brother, they don’t need a bra to be this perky. Anything else you want to test about your big sister’s big tits?”
Okay, I'm back!
Mmm
“Oh god, little brother, why won’t you notice my tight low-cut tops I’ve been wearing for you? Why don’t you notice the softer voice I put on while we’re alone? Why won’t you just fuck your horny big sister?”
“That’s it, little brother, just sit down on the shower floor. I’m going to use my huge tits on you so that all your future girlfriends seem inadequate. You can’t have me for good, dear brother, but I want you to always want me.&rd
“Is this how you play this one, little brother? Will you teach me how to ride properly?” My big sister went to the arcade more than I did, so I knew she was better than me, but I couldn’t turn down an opportunity like this. My heart
My whore of a big sister posts pictures like this to her instagram every time she plans on going out. ….so she posts them a lot. I used to feel protective of her, but soon I got jealous of all the guys who would be rubbing up against her.Â
I lied again
My little brother was thrusting a little harder, but I was still doing most of the work. He had a long way to go before I’d let him fuck other girls. He was an eager student, however. I’m glad that he’s grateful that he has such a helpfu
My little sister always seems so interested in what I have to say. Her eyes go wide and she always touches my arm. I try not to get the wrong idea, I really do…“
“Don’t lie to me! I can tell you’re hard through your jeans. I catch you staring at my tits all the time, but why is it that whenever I put on a naughty outfit for you when Mom and Dad are out, you suddenly lose interest? Don’t
“I really appreciate you picking me up after work, little brother. I know it’s really late, but I’m not tired. Do you have work tomorrow? Wanna just go back to my apartment and talk for a bit? I feel like we haven’t caught up in
Wow!
I always got so excited when my big brother told me I could suck his dick.Â
Keep Them Coming
“Hey big brother! I’ve been thinking a lot about last week. I know I said I never wanted to do that stuff with you again, but my pussy has been wet every night thinking about it. So I was thinking, maybe I was born to suck on your dick and
“You don’t have to be nervous because this is your first time and I have a lot of experience. That’s what big sisters are for: to teach their little brothers. Your cock is nice and hard, so just let me do all the work.”
“Like this, little brother? And for my next pose, can I bend over the couch? This is fun, but I’m getting impatient.”
I felt like shit. I didn’t know if I could go face my little brother out in the hotel pool after I just frigged myself off while thinking about him. Why was I such a pervert?
*note: caption edited from the original submission* “Um…” “What is it, little brother?”“I don’t mean to be rude, but, um, isn’t that shirt a little tight?”“I think it’s just tight enough,
Back to blowjobs
I’m so lucky that my big brother lets me suck on his delicious cock two times a day. He even lets me swallow!
“Okay, little brother, you win. I’ll blow you. But here’s the deal. If you can last longer than five minutes without exploding in my mouth, we can start fooling around all the time. But if you cum before the time is up, this will be
“*giggle* Stop it! I want to fuck again too, but we can’t do that all day, every day. Plus, I can see you going crazy looking at me in this bikini. I can’t wait until you unleash that pent up frustration on me tonight.” I know
“Thanks for going on a run with me, big brother! It’s been great spending so much time with you this year. I wonder what I did to make you like me again. Oh well, I was thinking of jumping in the shower, then do you want to go in the pool
I was ready to go and everything. I had snuck out of bed and got ready so that I wouldn’t wake up my sweet little brother laying beside me. I just didn’t have the time and I knew he’d want to fuck and I knew I couldn’t resist.
Text with picture: “like my new matching underwear? bet u wish u didn’t go away 4 the weekend, big brother!”
“Oh yes, please cum inside me, little brother! Fill up my little pussy with your hot jizz. You fuck me so good!”
“When I snap my fingers, you will wake up. When you do, you’ll have an overwhelming desire to please me and you will think that’s normal. You won’t tell anybody or act differently in front of anybody but me. But when we’re
Are you joining us or not, little brother? This is your 18th birthday present after all. Who knows when your big sisters will agree to fuck you again?
He was gone for the weekend, so I had to frig myself while pretending to suck on my younger brother’s cock. I didn’t expect to miss it so much.
“Yeah, you little perv? You like watching your older sister’s tits while she rides your big cock? God, I love fucking my little brother.”
Whenever we were bored, my older sister and I would watch TV in her room. We had been doing it for years. But recently I noticed that she stopped wearing a bra and started showing more skin. At first I thought she was teasing me for always staring at
It started off as endurance training. I would blow my little brother once or twice a day so that he could last longer with his girlfriend. But after he started taking longer than ten seconds to explode in my mouth, neither of us said anything. I think
“Oh my god, you’re so funny, little brother. No wonder you’re already such a hit with the ladies. I’d totally try to lock you down if we weren’t related.”
When my big busty sister offered to give me a massage, I was already excited at the idea. I had no clue that this is what she had in mind. It felt amazing, but I really hoped she was planning on a happy ending.
She could pretend I wasn’t related to her all she wanted by wearing that blindfold, but she knew as well as I did that she was addicted to her little brother’s cock.
“How about now? I bought this expensive corset that you requested and I’m wearing it for you. So won’t you please fill my pussy with your perfect cock? You’re driving me crazy, little brother!”
“It’s just us this afternoon, my dear younger brother. Why don’t I practice that underwater blowjob you’ve been asking for?”
I didn’t send this one to him either. My tits were growing, but I knew that my big brother liked them really big. I could only hope they had one growth spurt left in them. Although I knew at 18, it wasn’t very likely.
“This is all you’re getting, perv. Only my boyfriend gets to see my naked tits, not my horny little brother. You can jerk off if you want, but don’t get any of your nasty cum on my seats.”
My big sister and I always laughed at how over-protective our Dad was with her, but do you think this picture text took it too far? “hey lil bro, how mad do u think dad would get if he saw this? :p”
“You’re so sweet for taking care of me all weekend while I was sick, little brother. How about I take care of you now?”
