I have a feeling that this entire thread was created as an excuse to debate whether or not it's logical to be attracted to your sister. I understand the point, but you are stupid to think others are going to see that way even if for five minutes. It's not what they believe. I'm fairly neutral about alot of things too, and that doesn't make me a monster... but you should probably explain a little more.
I'm pretty sure the OP is exagerating some details, like the piss in the mouth, seriously that's an outright lie unless you and your sister are 40 something social deadbeats who were molested as kids. As for the anal sex, I have heard of incest relationships. First off it's quite easy depending on the circumstances, for example, in my case when my parents divorced I was 2, now my father had several children after me, his 2 oldest are 2 daughters, now I finally met them when I was 18 and the oldest one was 15 and she was pretty hot, but she is my half sister and I understand that so I will never try anything. However, there's some cases where the guy does try something, and in some cases it can just be a biologically full blooded sister and brother who have had divorced parents who took them apart and they haven't grown up at all together, when that emotional unity is taken away, a sister and a brother can very well be lovers, the only flaw in this is that siblings with the same two parents usually look alike, I mean seriously whether they want to admit it or not, brothers look the same and sisters as well, and yes a brother will either look like his sister or the other way around, that's how you get feminen looking guys, it happens when the mother's genes are stronger than the father's. Now, getting back to this, anal sex can be seen as neautral territory for some, because it doesn't carry the sanctity of vaginal sex, again I'm just trying to put this logically. Now I have even heard of siblings, like i have mentioned, emotional apart, practise sexual activity on each other, usually oral, like a brother, again, not emotionally attached to his sister, give her oral for practise so he can be better when doing it with his girlfriend. Now again, I must admit, I have heard a lot more of these no strings attached sex romps between cousins, 2nd and 3rd cousins, in fact a friend of mine fucked his 3rd cousin for years, but that is quite different from a direct sibling, because chances are you share several features.
You are a sick minded, retarded little wretch. You deserve death for your acts, you disgusting freak.
hahahahahahahahahahahahahahhahaahahahahahahahaahahahahahahahahahahahahahhahahahahhahahahahahahahahahahahahhaahhahahahahahahahhaahahah!!!!!!!!!!!!!!!!!!!!
Hey, Some cultures are different don't make fun of the ... ah what the hell.. If I knew you i'd beat the crap out of you, and then your sister for liking it.
Not cool.....I don't get how siblings can be sexually attracted to each other even if they are adults. Something definately went wrong in their upbringing IMHO
Well, i am in the process of tracing your ip and i will be reporting this post to the local police. You stupid, sick, twisted ****!
