Looking at her brother-in-law's slightly convex lower abdomen and the clothes and pants supported by something under her lower abdomen, Liu Yanmei's mind suddenly appeared the scene when she practiced "preparing skin" for the first time. The body of the www.biquge.info-brother-in-law leaned over step by step -- in fact, the scene at that time was "too late to say, but then fast"! However, because he was out of breath, his brother-in-law's movements that were as fast as the wind and as fast as lightning because of his desire seemed to Liu Yanmei, who was like a nightmare, like a "slow motion" in a movie! Finally, at the moment when the bodies of the two people first touched, Liu Yanmei collapsed into her brother-in-law's arms......

For a young girl, this kind of thing is the same as taking drugs, with the first time, she wants to do it a second time. As for the "brother-in-law who is duty", he has been doing his best to "take care of his sister-in-law" since then. The two of them would skip work and pry at the first opportunity, and then sneak home to taste the most delicious feast in the world. Afraid that my sister would find out, they often go outside to open a room during the day, and then pretend to come back from their work units and schools at night. In the initial stage of the rest of the college years, the slightly convex little belly of the brother-in-law became the "sufficient condition" for Liu Yanmei to reach the peak of desire! It is conceivable that the brother-in-law and sister should be a "duty" man when they are together, but the creativity of any man in xing affairs is amazing, and their impulse to experience novelties is also strong. In the process of falling in love with Liu Yanmei, his brother-in-law's creativity was fully explored, and he experimented with various tricks and postures that he imagined, created or stole from elsewhere on Liu Yanmei. And Liu Yanmei is also a very malleable person, they cooperate like a fish in water, water and fire!

However, in the process of treating a disease, the marginal effect of a specific drug will gradually decrease, and conversely, a disease will gradually develop resistance to the same specific drug. It's the same with Zuo love. The last emperor Pu Yi grew up in a pile of women, and the lack of necessary restraint and guidance made him premature and indiscriminately involved in Xing's life, and even became the plaything of adult palace ladies. At first, Liu Yanmei's body was very sensitive to her brother-in-law's slightly convex lower abdomen, but after doing more, it gradually became dull, until finally, they even had to use the stimulation of the yellow color video to reach the peak of desire. As a result, the slightly convex lower abdomen is no longer a "sufficient condition" for Liu Yanmei to obtain xing, it is only a necessary but insufficient condition! This is also very easy to understand, and the "pot theory" in the previous article is also used to make a specific analysis: a new pot, whether it is an aluminum pot or a casserole, is very sensitive to fire, and the water in the pot will be quickly heated, tumbled and boiled. However, with the increase in the frequency of use, a thick layer of dirt will gradually form on the inner and outer walls of the pot, like putting on a protective armor for the pot, which plays an "inviolable" protective role at the same time, but also plays an isolation role for the fire - the same fire, for the pot is no longer as sensitive as before. As a result, the casserole and aluminum pot with armor are no longer casserole and aluminum pot, but have become the third type of pot, a new "pot type" - stewed pot. - This is how the stewed girl is made!

In the following time, the brother-in-law's creativity gradually dried up, the armor of the stewed pot became thicker and thicker, and the "medicinal effect" of the ordinary yellow color video gradually lost. At this time, Liu Yanmei longed for a dose of "fierce medicine", eager to practice the abnormal and even violent scenes in the Huang color video! This is like a simmering pot with too much dirt and too thick longing for a more violent flame of tiang licking and polishing of iron sand balls, only in this way can the simmering pot and the water of desire in the pot experience the pleasure it deserves!

After graduating and being assigned to work in the People's Hospital, Liu Yanmei's scope of contact with the society suddenly expanded a lot. However, those men who do not have the "necessary condition" of "slightly convex lower abdomen" obviously cannot enter her eyes, but Gan Weidong and Chang Huizhuang, who only have the "necessary condition" of "slightly convex lower abdomen", have not been able to make her experience the pleasure she deserves.

Until I met Lu Yiming!

Lu Yiming was lucky, he didn't expect that his "bian" and violence, which he was afraid of by Pingping and other women, were just like the raging flames that burned and peeled off the thick dirt and the intrusive and injurious iron sand ball!
