Looking for specific Ten/Simm!Master fic

[tomato564.livejournal.com]

It was a long time ago that I read this, but I can't seem to find it anywhere. I've been looking for it for a couple of days now, but I give up - I just can't find it. I need help finding this.

It's Ten/Simm!Master. I remember the Doctor on the ground (on his knees, and I think tied up) with his sonic screwdriver set to vibrate shoved up his buttocks. XP

I think the Master leaves him like that, and then comes back, and finishes what he started.

Anyone know what I'm talking about? ^^;
