Ninesome

Sex involving nine people.

Kayla was sitting home alone when 8 boys showed up at her door. Each was shirtless and she smiled as they walked straight upstairs to her bedroom. On the way up she began stripping and tossing her clothes down. As she entered her room, the boys were sitting there waiting for her. She began kissing each one as she stripped them individually. After the boys were all naked they decided to take turns eating her out. By the time they all had a turn, Kayla had already orgasmed twice. Now she laid down and took one dick in each hand, giving two boys handjobs. She gave another boy a blowjob and then allowed one guy to penetrate her vaginally, another anally. Finally, the sixth boy was having mammary sex with her, as the last two each sucked on one of her tits while simultaneously jerking off. The two receiving handjobs came unto her face as the one receiving a blowjob came into her mouth and the guy having mammary sex with her came onto her chest, while the two sucking her tits each came on her stomach. She swallowed and then rubbed the cum off her stomach, chest, and face and ate that too. She orgasmed in pleasure as the two penetrating her thrusted at the same time. Now, all the boys switched positions and this continued until each boy had a turn in each positions. The night ended with Kayla's 13 orgasm as the boys left one by one by eating her out. It was the best ninesome in history.

Nilesy: A sweet, funny guy to hang around. He's always a bit awkward but nobody really cares. He's frightened easily so I wouldn't watch or play any scary stuff. He's also caring,nice, and kind. Not super smart, but yet not dumb either. Which is funny because he looks like a nerd, especially with his glasses and hair cut. He usaully has black hair and brown or black eyes. And he's scottish and takes quite the offense if you start hating on him because he'll think its because of his accent. He also LOVES computer games, except Slender, but one of his favorite games is minecraft. And he also loves his cat a lot.

My boyfriend just broke up with me and now I'm heart broken.
Girl, its a good thing he broke up with you, what you need is a Nilesy.

Ninety-Ninety Rule 

A rule for tracking computer programming development time.

The full statement of the rule is, "The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time."

The rule simultaneously emphasizes two important points in software development. The first is that for almost any product, most of the development time will be used on relatively small but difficult sections of the code. The second is that the first point often leads to extremely optimistic project schedules.

The ultimate lesson to learn from this rule is that the amount of the project that is completed is NOT tied to the amount of code completed, and that substituting one for the other can be disastrous.

The ninety-ninety rule is often mistaken for a typo, with users assuming that the first 90% of code should correspond to the first 10% of time; while this is logically correct, it is NOT the original aphorism.

A: "This stupid ten-line function is somehow crashing on one out of every 100 calls and nobody has a clue how to fix it. We've got a week left in the schedule and haven't even fully identified the problem."

B: "Ninety-Ninety Rule. You should have expected from the start that something like this would come up."
