Yes, this is real. Yes, it is mind-blowing. Yes, you're going to want to start doing pec exercises as soon as you're done watching this. Any more questions? No? Then, world, Meet Sara X!

There's not much to say about this video that's not already written in the description. Sara X is a model, freelance blogger and also a "tall, tattooed weirdo with an offbeat sense of humor" and a penchant for expressing her love for public domain music through the highly coordinated movement of her breasts. And for anyone wondering, Sara X says that the video isn't "fake or a trick, but my boobs are... no strings attached just plenty of silicone." Now if only she'd agree to come by the Jezebel offices and teach everyone to do this. Or just come by and teach me how to do it. I tried as I was watching and I think I broke a muscle. Please send help.
