No...I fuck upside down...

In an anti-gravity resometric, lubrisonic vibrational chamber.

Is it fun?

Of course it's fun! It's fucking!

Yeesh

I've only done it once

The guy I was with was quite strong (then again, I'm not very heavy) and he was standing up while he was balancing/bouncing me on him. It was pretty awesome & I'd like to do it again someday

What else do you do when there's only a broom closet available?

but is petite, so sometimes i have to try to stand tall/on my toes.
It's best when im facing the wall so i could be steady, feel his pressure against me, and so he could kiss my neck

then i looooove when he stands, and curls me

We are the same height, so that makes it possible.  With most of the gals I know, the height factor makes it difficult.

It is a nice change of pace.

Especially in front of a full-length mirror.  Love the way she looks when she's hanging onto the sides of the mirror with both hands and I get that double image of her.  It's also hot to see her watching herself get fucked.  Feels like making a porno.
I also had fun doing my ATF while she sat on a dressing table and vibed herself with her Hitachi and completely soaked the table.

I have the lady get on her knees on a high back sofa or bend on a low back sofa. Feels good feel.  I stand up on my feet while fucking her.

I was seated on the edge of the bed.  She was sideways to me with one foot on the bed and another on the floor (which makes it qualify as standing, possibly).  She suspended herself by putting her hands on the dressing table across from the bed and pumped herself up and down on me.
In the middle of it she gasped, "I think I just invented a new position!"  I asked her what we should call it and she said, "Spider Monkey!"
But I'll bet it's been done before.  Nothing new under the sun.

with some body types.  

I've always wanted to do a face fuck with a midget with both of us standing.
