一名男子被雇来演示如何有效地让女孩闭嘴，因此他带来了她的助手克丽丝·玛丽（Chrissy Marie），她将成为测试对象。 克丽丝的工作很简单：像往常一样不停地说话，而男人必须有效地让她闭嘴。 他试图用手捂住她的嘴，用尽最大的力气，但克丽丝咬住了他的手，那家伙不停地掐着她的手，但克丽丝不断挣扎和抵抗，所以那家伙想到了其他选择，脱下了克丽丝的袜子，然后塞进了她的嘴里。 这招有效，但克丽丝把它吐了出来，所以那家伙拿出一卷胶带，用胶带堵住了她的嘴。 克丽丝成功地把胶带撕掉了，这样那家伙就贴上了矿石条纹，但她仍然设法让它说话……所以现在是时候认真起来了，如果这家伙想在这个实验中取得成功的话：他把克丽丝的手粘在背后， 然后再次用袜子塞住她的嘴，然后再次用紧紧的缠绕胶带堵住她的嘴！ 现在事情正在发挥作用，克丽丝终于被有效地堵住了嘴，但事情对她来说还没有结束……待续

A dude has been hired to make a demonstration about how to keep a girl shut effectively, so he brings her assistant Chrissy Marie who will be the test subject. Chrissy's job is simple: to keep talking and talking as she always does, and the guy must keep her shut effectively. He tries putting his hand over her mouth and applying as much strength as possible but Chrissy bites his hand, the dude keeps handgagging her but Chrissy keeps struggling and resisting so the dude thinks in other option and removes Chrissy's sock then stuffs it in her mouth. It works but Chrissy spits it out, so the dude produces a roll of duct tape and gags her with a strip of tape. Chrissy manages it to remove the tape so the guy applies ore stripes but still she manages it to talk.... so it is now time to get serious if the dude wants to succeed in this experiment: he tapes Chrissy's hands behind her back, then stuffs her mouth again with the sock and then gag her again with a tight wraparound tape gag! Now things are working, Chrissy is finally effectively gagged, but things are not over yet for her... to be continued
