第三章(1/6)

第二天，芳又开始了对弟弟进行特训。距离星期六还不到三天，芳要在潋的面前逞威的话，这几天是不可停下来的。幸好是暑假与父母不在的关系，让她跟弟弟可以一整天都专注在那回事上。为了要让升变成性爱高手，芳今天又开始了淫媚的教授。
                                                                                                                                                                “升，你的缺点是持久力不足。所以我们今天要训练的是射精。”只穿了一件睡袍的芳坐在床上，看着赤裸下体的弟弟说：“你先自渎给姐姐看，要好好的控制，不要太快射出来呀！”
                                                                                                                                                                “这……”升有点迟疑的说。
                                                                                                                                                                “害羞吗？不用怕，姐姐跟你一起自慰……来，快开始吧。”
                                                                                                                                                                芳说着便开始自慰起来，她轻抚着自己的一双大奶子，抚弄着乳头，为了挑起弟弟的性欲，她还故意地低吟着：“嗯……嗯呀……咿啊……升……呀……啊……唷……”
                                                                                                                                                                被姐姐如此挑逗，升哪有不兴奋之理？本来软软的鸡巴马上便充血起来。芳看见弟弟因受到自己的诱惑而勃起，不禁得意洋洋起来，她娇媚的说：“升……嗯呀……来……跟姐姐一起自慰吧！”
                                                                                                                                                                “姐姐……”看着憧憬的姐姐的媚态，升不能自制，他走到床边坐下，左手握着鸡巴，慢慢的套动着。
                                                                                                                                                                “对了，一起来。”芳轻吻升的面额，然后各自自慰着。
                                                                                                                                                                “嗯呀……呀……好弟弟……”
                                                                                                                                                                “姐……”
