Why is it that two sisters having sex with each other is hot, but two brothers having sex with each other is gross?

My brother's new girlfriend. I cannot take my eyes off her everytime she comes round, shes so naughty. I love hearing her moan when they are having sex :O

What do you think?

I love my brothers cum 

I confess I want to ass fuck my sister in law when she shows her panties like this for me... I’ve already fucked her when she was my brothers gf.

I like big butts and I can not lie
You other brothers can't deny
That when a girl walks in with an itty bitty waist
And a round thing in your face
You get sprung
Wanna pull up tough
Cuz you notice that butt was stuffed
Deep in the jeans she's wearing
I'm hooked and I can't stop staring
Oh, baby I wanna get with ya
And take your picture
My homeboys tried to warn me
But that butt you got
Make Me so horney
Ooh, rump of smooth skin
You say you wanna get in my benz
Well use me use me cuz you aint that average groupy

Sister's that are a tease to there brothers are so hot. Especially the ones that randomly sit on the laps, rub there vagina's on you when they are in their underwear, and bend over in front of you. So hot!!!!!

i hate my brother. im a 42 year old divorced woman with a failed career and i'm barren even though my ex husband and I were trying for years. He left me to be with another woman who can provide him with a family. My brother is youger than me, has a great job and a very pretty girlfriend. so i get my own back when i visit by peeing on their toothbrushes and sometimes ill stick their toothbrushes up my pussy. I like the thought of my snooty bro and his gf unwittingly tasting me there.

I confess this is my first post, but i thought id share with you about a few years ago i was with a girl who was 19 years old, 5ft 5, and weighed about 100lbs. She was in love with me, but i just didnt want to be tied down at the time so she wanted to be my fuck toy, she would do absolutely anything i wanted without giving it a second thought. She wanted to do everything id ever mention, even the random things that no one planned were either great or just a huge turn on. One thing i still think about is she lived with her family in a single wide trailer, she had 2 younger brothers one about 17 and the other 15, one night with her brothers dad and mom home we were watching tv in the livingroom when her parents went to thier bedroom, and as soon as they did we went into the hallway bathroom where she started to suck my dick. It wasnt long before we were naked and i was fucking her over the sink, out of nowhere her brothers kept trying to come in on us and she was yelling at them to get out, they could have came in and joined for all i care. I ended up cumming on her face and making her walk in the livingroom before she was allowed to wipe it off and swallow it. I dont think her brothers even noticed because it was so dark.
There was another time i will never forget when i was working and she was home alone, her dad cut grass for a living and he had hired a guy she went to school with who really liked her, he was late one day and her dad just told him to go to thier house and he would come get him after the first job. Well she was texting me about it and he showed up, so she had him come in and watch tv with her until her dad got there, well while they were watching tv she layed on the couch on the other side of the room from him and text me. She ended up falling asleep, he got really brave and being as stupid as he was didnt care, so when she fell asleep he pulled his dick out and started jacking off. He actually went and stood over her and came all over her face hahaha, she jumped up and started punching him then she ran to the bathroom and text me about it while cleaning the cum off of her face. Being the pervert i am it made me hard just hearing about it. I told her to take a pic and send it to me, but it was to late she had already cleaned herself off. The only thing i didnt like about that whole day is i wasnt there to see it and do it myself.

Searching for a particular vid I used to love... before the wife found my digital porn stash and made me delete everything.. (divorced now so building up the collection again)

A mother 2 daughters and a son....I am not certain but the mom may be Rachel Steele??.. the oldest sister is about to leave home for college, so mom brings the younger sister into her son's room to explain how she will have to take over the role of fucking her brother when the big sister leaves - I think its to keep him settled and calm whiling studying or something?..

The youngest one is a little unsure but mommy insists... so the older sister shows her what their brother loves and how to blow him correctly... a great 3 way between the sisters and brother ensue.

My undying respect and gratitude to anyone who can help.

i confess after school and getting home my brother was always home before me from his work placement and he would take me to the bathroom to suck his cock.
