常常聽到有人說呼的不夠濃啦。明明燒了一堆吐出來卻是淡淡的。呼玩肚子痛啦。呼很多沒感覺啦。又聽有人說，要慢慢的呼，才會呼的濃，有些人呼的快了點，就會被指責說：不會玩嘛。

好了，老實說，這些問題只是生物學上的問題，由我來告訴大家是怎麼一回事。

我們呼吸的時候，常常以為可以用力的把氣吸進來，這是一種錯覺。為什麼呢？人的肺沒有辦法像是吸塵器那樣把氣體吸進來，人類的呼吸運動是一種很特殊的呼吸：負壓呼吸。

原理是這樣的：當我們的胸腔變大，壓力自然變得小於外面一大氣壓，因此空氣自動從外面流進來。

所以當我們吸煙的時候重點是：想像自己的【肋骨上升，橫隔下降】，想像自己的【胸腔變大】，煙自然會流進你的肺裡面。什麼是慢慢呼呢？也就是想像自己的【胸腔一點一點地慢慢變大】

然而【脊椎挺直】的姿勢比較容易讓胸腔變大，因此我自己覺得站直，或是跪直比躺著容易吸到煙，另外假如你燒的很濃，快速吐出來應該要是很濃的，假如吐出來只有淡淡的那麼就是有可能吸到胃了，這時候自己再旁邊試著讓胸腔變大練習幾次吧。

要不要憋著呢？當然照道理來說憋越久能夠吸收的成份就越多，但是一般的冰塊是混合物，包含其他可能不明的成份，所以該憋多久或是想怎麼做，就看自己的身體狀態與當次的冰塊狀態而衡量，我認為是較佳的策略。

那麼有沒有進入肺有這麼重要嗎？沒錯，因為苯丙胺指會從薄弱的皮膜與肺泡吸收入身體，腸胃消化道對它的吸收力很差。所以一定要吸到肺才會吸收到煙，另外注入肛門或是尿道也可以增加某些吸收，再來吐出的時候最好從鼻子吐，因為鼻腔粘膜也可以有一些吸收。

今天來分享一個小技巧 或許有不少人已經知道了 (尤其是我約過的一些朋友們 哈哈哈哈哈

做愛時 很多0號會為了想要感受到1號 刻意去夾對方 但其實當我們一夾 用了整個括約肌的力道去壓迫1號 不是所有1都擋得住這逼近15公斤的壓迫 更別說 如果我們是有練過臀大肌的人一一❞ 一不小心夾痛了對方 還得重新熱(機) 他還得調整 痛到後的情緒 況且 每夾一次 在放鬆時 就會鬆弛反彈 只會讓1號越來越沒貼合感 而我們越來越鬆

於是我們反其道而行 推屌出去 沒看錯 推對方出去 在對方進入身體後 深吸一口氣 ❝憋著❞ 請1頂在深處 然後我們用力推屌出去 接著吐氣放鬆後 身體壓力會自然內收 1號的硬屌就因為類似真空狀態的模式 被肉穴緊密的貼合 吸的很密實 而我們 不需要再一直用力夾了 只需要推他一次 就能放鬆享受那貼合的摩擦感 而穴穴也不會有鬆弛感 1號輕輕地動 兩人就會有超貼合的摩擦快感 Top也很容易就能找到 弟弟的G點 也不容易滑出 因為會被吸著

越是讓屌在深處時 推他出去 身體就會製造出錯覺 感覺被幹的更深 16公分會製造出 好像18公分大屌在身體內的感受 還能製造 好像 被強姦反抗對方的情趣

當然也可以在吸氣時 吸的是rush 順勢憋氣推屌到極限 然後徹底放鬆 吐氣 把身體交給對方 享受彼此的摩擦快感

這就是我的一個小技巧 不用一直夾 推他的屌一次 快感就能一直持續 而且 很容易讓1號繳械唷^^

下篇 我將分析rush的激情使用方式 長達10年的rush使用經驗 希望各位會有興趣

我不太喜歡當BTM，可能對方技巧問題所以我很抗拒

但前幾周一位大叔叫我在嘗試看看

他屌沒我大 但他很溫柔 

那一夜我第一次當BTM超過15分鐘

那一夜我被幹了8小時

那一夜我一直被幹射

被幹射的感覺真的很爽沒辦法形容

當他屌一直頂到G點 慢慢抽插

我敏感到在抖動 屌一直噴出精液 可能連尿都有

我真的無力招架 完全被他征服 讓他幹翻

他也射了3次給我…..熱熱的精液在我身體裡

他還不準我洗掉….因為要當潤滑
