Upside-down freaky lift!

My dance partner/teacher was trying to teach me a lift for the swan pas in which the end result is.....ok let's see if I can put it into words. He's holding my waist and lifting me right above his head, I'm upside-down so my back is against his back and my head is on his lower back, my right leg is straight out in front of me at a 90 degree angel to my body, and my left leg is bent and my toe is resting against his ribcage/sternum area. Yeah, it's complicated! We've tried it twice and last night was the first time it actually worked. The hard part is getting into the final position. To get there you(the girl) have to ignore all common sense and once he starts to lift you, you have to pitch your body backwards for all your worth. The first time he tried it with me I was scared and didn't lean back enough and I ended up on his shoulder instead of over his head. Then he had to just talk to me and get me to trust him. I already trust him, but I've never been scared at any other lift and I told him it freaked me out. He told me that was natural but we needed to go over the mechanics of it so we both didn't end up on the floor. And then is finally worked! I knew it worked when it felt uncomfortable and when I could see myself upside-down in the mirror. Yeah, 1 more stunt down, a lot more to go!!! I'll post pics as soon as we do it again so you can see what it looks like.
