Big sister who holds her sister’s head in her arms and pets her hair while she has the most leg-trembling, sweaty, hyperventilating, near-sobbing orgasm inside her, occasionally kissing her and whispering affirmations

The first time I walked in on my big brother masturbating, I was shocked. I didn’t know what to say or do. It was totally embarrassing, and I was even more confused by what I saw on his computer screen. A still picture of a naked asian woman. A little boring, if you ask me, someone who’s been jacking off my little clit for as long as I can remember to all kinds of porn, and in all kinds of ways. I expected a bit more creativity from him, but there he was, sitting in his gamer chair at his PC, and instead of playing runescape like normal, he’s got his massive cock in his hand.

He’s pretty shocked that he got caught and just stares at me for a beat, and I’m certainly too afraid to say anything, my jaw dropped, then before I can stop myself, my eyes have dropped to his still-hard cock. I hadn’t seen it since we were little and still took baths together. It was pretty tiny back then, nothing like the….6 or 7 inch girthy monster I’m seeing now. Finally he breaks the silence with a clearly embarrassed “Why don’t you take a picture, it’ll last longer” older brother quip. A classic, but I can’t find the words to respond as quickly, no snappy comeback because even though he’s my brother, this is the first time I’m seeing a real dick in person, in the flesh, and I kind of do wish I could take a picture right now…but I snap out of it.

“Sorry bro, you really need to lock your door if you’re gonna be, you know,” I trail off, distracted by his foreskin that he just casually pushed back up over his cock head, right in front of me. I reach up to my mouth subconsciously to check for drool, surprisingly there is none. I expect him to put his cock away next, zip his pants and make another dumb joke to ease the tension, but instead he asks “is this your first time? seeing one, I mean,” he adds at the last second, getting flustered. Is he actually blushing right now?

It can’t get any more awkward than this, so I decide to be honest. Fuck it. I’m starting my period in a few days, which always makes me extra horny. I can’t stop myself from saying “yes. Can I touch it?” This time, his mouth drops open in surprise. The silence between us is palpable, all of the oxygen sucked out of the room with a single question. His cheeks are bright red at this point, and I’m sure my freckled face is just as pink as the inside of my now dripping cunt. I’m terrified, but I’ve also never been so horny or wanted anything so badly, and I had a feeling he wanted it, too.

He tried to say something but his voice caught in his throat, and instead, he nodded his head slowly, never taking his eyes off of mine. I grabbed a beanbag chair from the other side of

my mouth. “Don’t say anything,” he said quietly. “This is pretend. Nothing that happens in here is real, okay? We’ll never talk about it again. Just don’t stop,” he pleaded.

The look in his eyes could only be described as hungry. I had no idea how true that would end up being. But for now, it was my turn to devour my brother’s gorgeous cock, as much as I could fit in my small mouth, that is. My hand still on his shaft, I sat up on my knees on the beanbag chair and put the tip in my mouth, relishing the delicious salty taste. He moaned immediately, but only loud enough for me to hear, since Mom and Dad were in the kitchen making dinner. We had to be quiet, but we had at least an hour of uninterrupted time we could spend before the “dinner!” call would come from one of them. They never came to get us, so I felt pretty safe, even with the door unlocked.

My tongue lapped circles around the head of Trevor’s cock, while my hand worked up and down his shaft, like I’d seen in porn. I had a fascination with foreskin, so I slid my tongue underneath his, moving it in circles while my fingers massaged his foreskin from the outside. I wanted to see how deep I could get it inside my throat, so I slid down his shaft slowly but

Big sister found mom's old maternity dress. The ones designed for easy breast feeding. And she only wears them when it's just her and I. She keeps running and sitting so that the flaps shift revealing her breasts... why... why do I keep imagining nursing from her? From my big sister? #incest #siscon

It's a cold damp rainy day. Making it perfect cuddle weather. Mom, Dad, sis, bro and I all snuggled up under a blanket watching the rain on the window. Warm comfortable and naked. Truly the best family time

Big sis just stopped washing my body after sex to answer a text. That's so rude of her!

Then she sees my face and says "Don't worry I was just telling our brother I can talk later. I am busy cleaning out my favorite sex toy"

"......."

Concept: Little sister leashed by the front door of a party. A sign pointing to her mouth says "unfinished drinks go here". A sign pointing to her #diaper says "consumed drinks go here".
