Nani 没想到她的私人教师竟然会用如此反传统的教学方法，把她牢牢地绑住，嘴里塞满内裤和袜子，并用泡沫胶带紧紧封住！

可爱又甜美的 Nani 今天在家请了一位私人数学老师，希望能得到一些学习方面的帮助。面对“二加二等于几？”这个难题，Nani 热情地回答道：“五！”哦，Nani——要是早知道接下来会发生什么就好了，你肯定会更努力学习！

这位老师一如既往地专业，对这种情况早有准备，决定采用一种颇具创新性的教学方法。首先，他用手捂住 Nani 可爱的小嘴，阻止她胡言乱语。“嗯嗯嗯嗯！”Nani 抗议道。但随后，老师抓起一卷胶带，熟练地绑住了她的手腕、双腿和胸部，让她做好了下一阶段课程的准备。

这时，导师从附近捡到一条内裤，揉成一个大小合适的球，塞进了Nani的嘴里。Nani不确定内裤是否干净，于是要求换一根香蕉！导师运用概率论，在香蕉和内裤之间随机做出选择，（对不起，Nani！）内裤赢了，完美地填满了她的整个嘴巴，掩盖了她数学上的矛盾：嗯嗯嗯嗯嗯！

为了封住这堵嘴，他从Nani鼻子下方到下巴下方，甚至鼻子上方，整齐地贴了几条胶带！这种方法能帮她算出二加二等于多少吗？恐怕不能。Nani试图用手指撕掉胶带，但导师及时回来了：“你想把它撕掉吗？我有更好的东西给你！”会是什么呢？

课程继续进行，又一次教学上的创新：老师脱下她的一只袜子和内裤，把它们塞进她的嘴里，让Nani惊讶得睁大了眼睛。现在她的嘴被塞得满满的，准备用一层又一层的微泡棉胶带密封起来，绷紧并牢牢地贴上。“嗯嗯嗯嗯嗯！”在一片寂静中——没有数学错误——课程终于开始了。

然后，老师用实际演示教Nani二加二：他用马鞭在她左右脸颊上各抽两下，让她把结果加起来。“嗯！嗯！嗯！嗯！”Nani，你做得真棒！但接下来还有很长的学习时间。Nani能通过即将到来的考试吗？观看完整视频，揭晓答案！Nani had no idea her private tutor would use such unconventional teaching methods, leaving her firmly bound, her mouth stuffed with her panties and socks, and sealed tightly with microfoam tape!

Adorable and sweet Nani is hosting her private math tutor at home today, hoping for some help with her studies. Faced with the challenging question, "What's two plus two?" Nani enthusiastically responds, "Five!" Oh, Nani—if only you knew what was coming, you might have studied harder!

The tutor, ever the professional, is prepared for situations like this and decides to employ a rather innovative teaching technique. First, he covers Nani's cute little mouth with his hand to stop her from spouting mathematical nonsense. "Mmmmmppph!" protests Nani. But then, the tutor grabs a roll of tape and expertly binds her wrists, legs, and chest, leaving her all set for the next stage of the lesson.

At this point, the tutor picks up a pair of panties he found nearby and rolls them into a perfectly sized ball to stuff Nani's mouth. Nani, unsure if those panties are clean, requests a banana instead! Using the theory of probability, the tutor makes a random decision between the banana and the panties and (sorry, Nani!) the panties win, perfectly occupying her entire mouth and muffling her mathematical inconsistencies: MMmmmmmmppph!

To seal this masterpiece of a stuffed mouth, he applies several strips of duct tape neatly, from just below her nose to under her chin and even over her nose! Will this method help her figure out what two plus two equals? Probably not. Nani tries to peel the tape off with her fingers, but the tutor returns just in time: "Were you trying to take it off? I've got something much better for you!" What could it be?

The lesson continues with another pedagogical twist: the tutor removes one of her socks and panties and stuffs them completely into her mouth, leaving Nani wide-eyed with surprise. Now her mouth is extra stuffed and ready to be hermetically sealed with layers and layers of microfoam tape, stretched tightly and applied securely. "Mmmmmmpph mmmmmmppph!" With this silence—free of mathematical errors—the lesson can finally begin.

The tutor then teaches Nani to add two plus two with a practical demonstration: he gives her two spanks on each cheek with a riding crop and asks her to sum them up. “MPH! MPH! MPH! MMMPH!” You're doing great, Nani! But there's still a loooong study session ahead. Will Nani pass her upcoming exam? Find out in the full video!
