十八招变身“狐狸精”

Hi, I used to be a member of this forum in the old days (>10yrs ago) and had just re-registered as a newbie today. Really glad to see Sammy Boss is still around and many more bros here...

Just something to share from a site that I visited (can't remember where). Please pardon me if someone had already posted this. Here it goes...

第一招:狐狸精之美

狐狸精是美丽的,包括脸蛋、腰条、素手、玉足等。要是一张口便是年久失修的四环素牙,一出手便是勤劳致富的 四个大茧子泡,一投足则是懒婆娘裹脚布臭倒一公交车,那就与狐狸精无缘了。


第二招:狐狸精之香

战士上阵不能不带枪,女人出门不能不带香。女人香也在于经营与点缀,淡淡的香水轻施,腮边耳后方能吐气如兰 ,秀发始做雾鬓风鬟,手臂宛若皓腕香雪,玉足似莲步轻移,大腿跟处暗香浮动。狐狸精就可身带一种让男人五迷 三道心荡旌摇的迷魂香,万丈红尘任尔行,老爷们天下舍我其谁?耶!


第三招:狐狸精之媚

狐狸精的媚是一种力量,是从骨子里透出来的与众凡俗女人不同的气质。只要媚功一放男人的身体里的骨头就会嘎 嘣嘎嘣碎裂得直响,试问哪个男人能够抵挡得住!当狐狸精那媚的眼神浅的笑意款款奔你而来那绝不是风骚,那是 狐媚子固有的自信心和穿透力。


第四招:狐狸精之柔

河东狮吼的女人永远也做不了狐狸精的,女人是水做的要柔,得像杭州丝绸一样轻薄柔软。柔情似水款款温情,才 是男人心灵永远的渴望。


第五招:狐狸精之魅

魅力不需要有多张扬,但能让男人一眼就沦陷。就算是不漂亮也一定是风情万种的,把自己最可爱最迷人的一面展 现出来。她们走在街上就是一道流动的风景线,让人赏心悦目过目不忘,也许仅仅是一颦一笑也能动人心魄勾人心 眼。


第六招:狐狸精之妖

狐狸精凹凸有致玲珑有形轻盈婀娜娉婷多姿杏眼如丝性感撩人,是集妖艳、妖冶、妖媚于一身的小妖蛾子。那斜睨 而暧昧的眼神,那性感而诱人的嘴唇,总能活脱脱地把男人的心思都扭了进去,因为那妖气从骨髓里散发出来。狐 狸精风骚而绝不下贱,不是风尘女子赤裸裸的挑逗。更不像那种走到街上添胸摆臀的鸡,一张嘴便是惊雷:“大哥 ,发生关系不?”


第七招:狐狸精之野

狐狸精野性狂放脱俗无羁,就如未经世俗污染的清纯自然,不受规矩约束的自由洒脱。这种野有些类似聊斋里的狐 狸精婴宁姑娘,听她咯咯一笑就会觉得她像赵忠祥解说的来自辽阔草原的野生动物,散发出来的是原始的野性和磁 性,男人的思维马上就跟着活跃起来,不由自主地想跟着她一起律动。野性的张狂是最能勾起男人的征服欲的,西 施捂心楚楚动人只能引起男人无限的爱怜,可很难激发出男人心底最狂热的渴望。野性的美还如远山顶上一朵艳丽 怒放的野花,尽管花枝上带着刺儿,可依然撩的男人心头火生耐不住伸手攀折。


第八招:狐狸精之嗔

不会的嗔的女人仿佛是不会动的充气娃娃,缺少了灵动娇媚欣快之气。一边用男人的卡刷个大钻戒,一边猛戳他的 脑门儿似怨非怨地嗔道:“你可真坏哦!”此时此刻坏与不坏已臻化境,纤指一出四两拨了千两雪花银。男人则以 成功征服而引以为人生快事,因为没什么能比博狐狸精女人一嗔更重要。


第九招:狐狸精之娇

一幅娇滴滴的模样,或如林妹妹般的痴情、任性,如果逼近更年期就须老黄瓜刷绿欺装一把嫩了。用好娇功,狐狸 精娇弱可怜楚楚动人小心翼翼地跟帅哥还没混熟,就可以开始若有若无地勾眉搭眼欲摸还休,成就一个地道的让人 怜让人爱的小蹄子!


第十招:狐狸精之嗲

女人时不时地发点嗲,嗲的得天时地利恰到好处,嗲得男人找不到北,那便是功夫。无数的笨女人以为可爱就是学 嗲,嗲得毫无来由且令人毛骨悚然,仿佛日光光突然起了一阵子阴风,连邻居家正在发情的老猫见了她也要溜着墙 根走掉。


第十一招:狐狸精之文

这应该是一种文静,但还更应是一种文化。最好你能半夜上网写写心情文字,对月抒情敲键盘落泪一幅文君、清照 的遗韵风情。爱呀恨呀那滚着颗颗相思红豆的撩人帖子,保准儿让帅哥靓男激情荡漾爱你不回头。


第十二招:狐狸精之哭

哭功绝对是可以浇进男人的心田雨露,长出爱来长出人民币来的。不过不可披头散发光着脚丫子嚎啕大哭,须珠泪 暗滴粉腮楚楚可怜,记着哭出效益来方为上乘。


第十三招:狐狸精之量

妒本是封建时代七出之一,有肚量则不妒。狐狸精须有大量有雅量,容得大千世界春夏秋冬雨雪风霜。一任口水粪 水飞扬,不屑于家长里短婆媳大战,瞅准了的事咬定不放松,腹中装得另一番天地。


第十四招:狐狸精之玄

玄是什么?是神秘感,神秘了男人就永远做孙子。男人越不了解女人,就越爱瞎猜女人心思。狐狸精利用这一点, 把男人的胃口牢牢吊在一棵树上,像个啄木鸟非要钻进树心看个究竟。享受暧昧的那种感觉,有一点点喜欢有一点 点距离,让男人琢磨不透,想要靠近却发现只能远观而已。引而不发跃如也,别轻易松手,抗日到底 馋死他!


第十五招:狐狸精之智

狐狸精极具素养、学识,对事的判断对男人的鉴赏,处处体现其睿智敏慧。运筹帷幄决胜千里的本事一点都不比老 爷们差,已经百毒不侵百鸟朝凤百炼成钢了。狐狸精耍出闪展腾挪的手段,先勾起男人的兴味,当他欲一窥究竟时 ,狐狸精随即摆出正襟危坐的架势拈花微笑,使男人意乱情迷欲罢不能永远拜倒在石榴裙下。她们从结婚那天起, 就深知情感的杂草有害幸福,她们会精心呵护自己的小窝。她们有足够的心眼,无须暧昧的蓝颜知己照亮或点缀生 活。她们不一定非得做一个思想的男人,只要学会站在男人的肩膀上就可以了。


第十六招:狐狸精之修

佛说,你心里有荷花,眼前就盛开荷花;你心里有大粪,眼前就堆满了大粪。你先面对一条底裤一卷手纸修成九阴 真功,接着想那个能为你刷卡和埋单的男人,从无到有见景情生直至爱的花招爆棚,修成正果勾引比自己更强的男 人成裙下臣。花木兰卸甲之后回乡下做了花姑娘,坐在那分不清是东阁还是西阁的床上对镜帖花黄,把同行十二年 的男伙伴们馋得直迷糊,那才是百炼钢成绕指柔。


第十七招:狐狸精之度

狐狸精脸儿靓心儿硬下手稳准狠,对男人有着超一流敏感度和拿捏的分寸。狐狸精抓住男人渴望刺激又离不开家庭 港湾的心态,时时用质地温柔适度的妩媚将其非分之想扼杀在萌芽状态。狐狸精也不会整天打扮得光鲜可人,以至 养刁男人的贼眼,狐狸精深知热情万不可过火。


第十八招:狐狸精之德

狐狸精风情万种可以倾倒众生,绝不做大众情人却只痴迷一人。爱便爱得干脆爱得清澈爱得纯洁。狐狸精还拿得起 放得下,对于不值得爱的人绝不感伤和有片刻迟疑,拂之而去就似赶走一只苍蝇。

Re: 十八招变身“狐狸精”

I don't think any woman can learn all these things unless:

1) She is BORN with those characteristics,

2) She was taught to do all these at a very young age under very controlled supervision,

3) Some shit happened that caused her to force herself to transform into one,

or

4) She is a REAL fox-spirit!

Dear, for sure that 男人有选择。。
试想想,为什么他们要在外面找女人,偷吃,一夜情,或包二奶呢?
一个手掌拍不响啊。。事出必有因的。。
当事情发生时,有时也不要只怪男人。。女人们啊。。自己也要检讨哦。。

一段美好和坚固的感情。。会很容易被第三者乘虚而入吗?

别用狐狸精这字眼好吗。。WE ALL ARE HUMAN BEEN..互相尊重很重要。。

Re: 十八招变身“狐狸精”

Bro WB,

One man's meat is the other's poison. Each of us has unique preferences and whether you can find one depends on your chemistry between you and her. This type of "狐狸精" is "可遇不可求". If you ever find one, do be careful, other than burning a big hole in your pocket (which can easily be mended), the wound in your heart will stay with you for life!

Personally, I have had a 6-month relationship with a PRC KTV hostress. For me, she is my "狐狸精". The love I felt for her is more than what I had for my wife during our (my wife and I before married) courtship days. If it is not for my responsibilties towards my kids, I would have divorced my wife to marry her. Dangerous right? During this period, I was in heaven. Have you ever encounter a cunt that is literally tailored to your dick? In addition to bring her out for meals, shopping, and leisure, we made love twice a week with each session lasting at least 3 hours. The strange thing is, I never seem to get tired of her. Each time is a new experience and I can only get "hungrier" the more I do it.

Below is something that I wrote... and you'll know how I felt. Enjoy!


六个月的起起落落


前记

自从那天遇到你,
我心被你偷了去,
还把毒药下嘴里,
舔了魂魄也散去,
现在天天想着你,
上班没力也没心,
只怪当年为棵树,
早把森林给放弃!

不知不觉爱上你,
生活过得很写意,
吃饭打球超开心,
无时无刻想着你,
经过无数的努力,
终于想信你的心,
真想一切都放弃,
只为和你在一起。

今日记


今天终于又见你,
你有心事我痛心,
带你吃饭买东西,
还把零花给了你,
为的就要你开心,
问题我会好考虑,
是否能全答应你,
不断你财看心意。

后记

不知什么时候起,
感觉开心没踪影,
你心开始离我去,
要的已经给了你,
跟我再也没利益,
把我感情当垃圾,
谎言一句又一句,
背弃我们的协议。

看来我真白费力,
莫怪我没好珍惜,
也非我觉没新意,
是你逼我心死去,
现在我要多努力,
把毒一一的解去,
就当那天没遇你,
半年回忆收心里。

六个月的起起落落

...........................
Hi Bro LotusKid,

Ths for sharing ur escapade w/ a 狐狸精. I hv not had the good fortune of meeting one perhaps bcos of my brief BY-ing experience of only 14 months.

I was quite fond of n had some KC for a 19 yo student (she is my avatar). We were together only 2 months. Even though she has one of the prettiest pink pussies n she repeatedly told me she loved me, she was no 狐狸精. She cared more abt our RS than I did in the first month, but the power shifted to her favor in the 2nd month. That was my mistake n my changed behavior must be very unattractive to her. She fell in love w/ a 20 yo fellow student from her hometown less than a month after I returned to Gotham City. She n her older cousin both blamed it on me! Luckily, I was able to forget her very quickly.

Kudos to ur poem. I guess u hv not forgotten her completely.

Cheers!

Bro WB
