体位训练为什么会有劈叉式?(2/5)

“该体位虽然是骑乘位的一种，但主要还是由攻方进攻。由于受方悬空，攻方不会受到体重的压迫，能很方便地向上顶。还能充分享受双腿悬空张开，毫无抵抗力的受方一边忍受疼痛、一边任攻方玩弄的模样。所以，宿主不用勉强自己动也可以的。”

到底什么样的性交情景要在台阶上进行？！魈几乎晕厥，感到忍无可忍，咬牙切齿地按下退出按钮，系统提示再一次响起。

“钟离大人……真的会喜欢这种吗……”

“不早说！”

他开始怀疑起训练的意义。在忍耐到极限时，系统总算响起“当前体位演示完成”的提示时，他才如释重负地瘫软下来，按揉自己拉到极限的韧带。

“该体位由攻方坐在沙发上，受方张开双腿，双腿架在沙发把手两端，双手撑着椅背，以劈叉的方式完成性交。受方以强大的爆发力，在一瞬间分开双腿至极限，并用重力将攻方性器压入深处，讲究一个快准狠，提供强烈的视觉冲击力。缺点是不便后续运动，需要攻方辅助。”

“宿主要放弃吗？将不保留之前关卡的奖励。”

魈大怒。早知道就不动得那么卖力了！他在心里怒骂系统，才后知后觉地回味起系统刚才的描述，便于钟离大人进攻和玩弄的……体位吗？代入与钟离大人交合的情景，他一下子羞耻不已。如果是这样，也不算白学习……吧。

既然选择了这个任务，魈也不好中途退出，只好再咬牙努力一把。好在他长年靖妖降魔，各种基本功都很到位，许多招式也是需要足够的柔韧性才能发挥出来的，区区一个劈叉还不是什么难事。只是腿一旦劈开，要想收回来就变得非常艰难了。魈眼睁睁地看着自己的腿分得越来越开，岔开的速度快得失去了控制，然后噗地一声把身下发光的教具给吞进了穴里。

解说结束后，面前的教具的形态也有了变化，发光的柱状物被垫高了一些，它一左一右分别立起两根略高的桩子，看起来在模拟沙发的形态。

本章尚未读完,请点击下一页继续阅读---->>>

啥……？！

正沉浸在假象里动得热火朝天，后穴里的光柱忽地消失了。魈如吃了颗空气胶糖，外面的糖皮才刚刚抿化，里面的气就砰地炸没了，整个人又茫然又恼怒，他刚想点开系统要个解释，提示音就响起了。

魈赶紧用手撑住地面，慢慢找回以前练童子功的感觉，终于，他的整条腿展开至与地面完全平行，教具也矗入了后穴里。但这还没完，要想把教具完全吞进去，他必须再让自己的身体再往下陷一些才行。他一点点拉长韧带，眼角因久违的疼痛而渗出了几滴泪水，终于，教具彻底地插入了后穴。

“已更换完毕。当前演示体位：劈叉式。”

“……但这样……要怎么动……”魈艰难地维持着姿势。他的双腿架在桩子两端，悬空在外，几乎借不到力，所能依仗的只有自己的手臂与腰背，只能一次次扶着椅背，把自己吊起来，再卸下力道用重力把自己摔回去。饶是体质异于常人的降魔大圣，这么几十个来回下来也是浑身汗水，韧带也一次次遭受冲击，让他疼得直颤。

“休息时间结束，开启下一个关卡。当前演示体位，倒立式。该体位由攻方站在台阶上，受方双手撑在地面，头朝下，利用核心的爆发力将下半身上翻。攻方抓住受方双腿，插入后穴之中。”

为了完成体位训练，他的身体赤裸了一下午。他在地板上找到了自己随手脱下的衣服。他本来准备穿上，可刚撑开袖子，他就生出了一股反感。

p; 不行，这个只是教具而已，他怎么能对钟离大人的以外产生感觉！他咬了咬嘴唇，把注意力集中在单纯的练习上。他努力想象着身下躺着的是钟离大人，卖力地移动腰肢让肉棒摩擦后穴，又在即将坐到底的时候放缓速度，不让自己一口气重重压在钟离大人。

往好处想……这是一次很不错的体能训练，而且尽是学习了这辈子都用不到的小众体位，等真的和帝君翻云覆雨时还能保留一丝青涩，带给帝君雏子的……不！他怎么又在想这种失敬的事情了，帝君有没有这份兴致临幸他还不好说呢。他沮丧地摇摇头驱散这种念头，挣扎着爬起身，准备为晚上的任务做准备。

可恶，沉没成本……

“检测到宿主的身体素质优异，为保证训练质量，正在为宿主匹配高难度关卡。”

魈陷入呆滞，看着屏幕跳出的一行行字解说，险些怀疑自己不认得璃月字了。快准狠？爆发力？性交……需要这些吗？

“………………”

黄昏，魈与系统提供的诡异体位的大战总算告一段落，他筋疲力尽地躺在地板上，手里抓着他好不容易换来的睡眠药，连一根手指头都懒得动弹一下。

“哈？？”

真不想穿啊。想要继续赤
