I sat naked on the bench in the health club locker room, staring at the tiles on the floor between my feet, but really looking at nothing. I was waiting for Barack to decide to come up and talk to me. He was this muscular teenage nigger who frequented the club and had ruined my life in the last few weeks. I was ordered to sit naked on the bench without a towel or anything to cover my nakedness. I had to keep my legs spread and my cock and balls visible for the anyone in the locker room who wanted a look. I knew instantly that it had been a mistake to sign up at the inner city health club which was eighty percent black, but it was near my house and cheap which was even more important.

The harassment had started on my first visit. Dark skinned, muscular black boys bouncing around the locker room with their huge dicks and pendulous sacks of balls swinging, high fiving each other and laughing and rapping, and there I was, this moderately built white guy of thirty two.

I will never forget coming back from the shower and one chocolate skinned thug of about eighteen let out a "weeeeeeeow" kind of sound and then said very loudly to me, loudly enough for all his pals to hear, "White man, how the hell can you fuck wit such a small dick?" They all roared with laughter and I turned bright red. Before I left that first time, I met Barack. He eased up to me while I was packing my gym bag. He is one good looking darkie, I will say that for him. He flashed me a big white toothed smile and said he hoped I wasn't thinking of quitting the club. He said he was friends with the manager and they had my address and shit, and it would be really unfortunate if I decided to quit. Then he laid one large basketball player sized hand on my shoulder and said that he would see me at the same time the next day.

Well, that's how it started. It got worse each time I went to the club. Barack and the other niggers got me to get towels for them, had me scrub their backs in the shower, even made me pick their dirty stinking jock straps up off the floor. They sent their filthy jocks and socks home with me to wash for them.

Now let me state here once and for all, that I am in no way at all gay. I don't think I ever even had a gay thought. So all of this really repulsed me. They would brush up against me so their big fat black dicks rubbed my body. They would make constant jokes about me being a faggot.

So I had it out with Barack. I told him I was a single parent with a thirteen year old daughter and in no way gay, and I wanted to quit the club. That mention of my daughter was the biggest mistake of my life. Barack demanded to see a photo of her. Her name is Crissy. After that, all they talked about was "Crissy the Cunt" in the locker room.

"Some fourteen year old school boy probably shoving his dick in her right now while you is at da club." They would say things like that. Barack would ask, "Do you suppose she had ever sucked black dick?" I told them she was totally innocent, and they should keep their foul mouths to themselves. They beat the shit out of me.

I didn't go to the club for a week. All the windows were broken on my car, and my newspaper was stolen, and somebody pissed all over our door. I received a package at work, and when I opened it, there was a pile of shit in a box. I was going nuts with anguish. I thought of going to the police, but I knew I would face even worse if I did. So I went back to the club. That was two months ago. A lot had happened in those two months.

Now I sat waiting for Barack to speak with me. He walked up, stark naked. The first thing I saw were his huge brown feet next to me. I looked up at his long muscular legs. How could I miss the seven inch flaccid dick, thick as a flashlight and the ball sack that looked like it had oranges in it. It was fucking obscene. His stomach was hard and tight. His ass was one of those round tight nigger bubble butts. His c

TFA is an extremely well-written, easy-to-follow tutorial. I "played along at home" (well, at work, actually) as the author recommended and exploited a system on the first try. Great stuff!

Hang on, one of our SysAdmins wants to talk to me about something.

Hey since you think you're such a funny guy I've got a joke for you!


What do you call a nigger with a stutter? A cocoon!

What's the difference between a black welfare mom and an elephant? About five pounds.

Why did a nigger commit suicide? Somebody tossed a bucket of KFC into traffic.

Why is Stevie Wonder always smiling? He doesn't know he's black.


Those are at least as funny as your lame-ass predictable joke. Niggers!

easy on the 'civil' part by our reckoning.

you do still have the right to remain silent.

greed, fear & ego (in any order) are unprecedented evile's primary weapons. those, along with deception & coercion, helps most of us remain (unwittingly?) dependent on its' life0cidal hired goons' agenda. most of our dwindling resources are being squandered on the 'wars', & continuation of the billionerrors stock markup FraUD/pyramid schemes. nobody ever mentions the real long term costs of those debacles in both life & any notion of prosperity for us, or our children. not to mention the abuse of the consciences of those of us who still have one. see you on the other side of it. the lights are coming up all over now. the fairytail is winding down now. let your conscience be yOUR guide. you can be more helpful than you might have imagined. we now have some choices. meanwhile; don't forget to get a little more oxygen on yOUR brain, & look up in the sky from time to time, starting early in the day. there's lots going on up there.

"The current rate of extinction is around 10 to 100 times the usual background level, and has been elevated above the background level since the Pleistocene. The current extinction rate is more rapid than in any other extinction event in earth history, and 50% of species could be extinct by the end of this century. While the role of humans is unclear in the longer-term extinction pattern, it is clear that factors such as deforestation, habitat destruction, hunting, the introduction of non-native species, pollution and climate change have reduced biodiversity profoundly."

"I think the bottom line is, what kind of a world do you want to leave for your children," Andrew Smith, a professor in the Arizona State University School of Life Sciences, said in a telephone interview. "How impoverished we would be if we lost 25 percent of the world's mammals," said Smith, one of more than 100 co-authors of the report. "Within our lifetime hundreds of species could be lost as a result of our own actions, a frightening sign of what is happening to the ecosystems where they live," added Julia Marton-Lefevre, IUCN director general. "We must now set clear targets for the future to reverse this trend to ensure that our enduring legacy is not to wipe out many of our closest relatives."

no need to confuse 'religion' with being a spiritual being. our soul purpose here is to care for one another. failing that, we're simply passing through (excess baggage) being distracted/consumed by the guaranteed to fail illusionary trappings of man'kind'. & recently (about a 1000 years ago) it was determined that hoarding & excess by a few, resulted in negative consequences for all.

consult with/trust in your creators. providing more than enough of everything for everyone (without any distracting/spiritdead personal gain motives), whilst badtolling unprecedented evile, using an unlimited supply of newclear power, since/until forever. see you there?
