First issue was to rip out the legs and arms without falling over myself, while I could have dismembered my own parts and rip them out this would have been extremely troubleful with my thighs since I want to throw them up while having the illusion I still have some. So I teleported my parts away and Ukes parts to where mine would be, grab them and teleport my pieces back. Then I pull them out of me.

so I'm still fully intact and simply made the replay like normal, I hacked the knee dm and skeeted it, moved on and threw it on the ground. I recorded the replay with this script and made a mod in which my leg is twisted normally.

I replayed the recorded replay with the new mod and removed the dismemberment so the leg would reattach when I get close to it.

I continued to make the replay until I wanted to untwist my leg.

I recorded that replay again and made a new mod again. In this mode the leg doesn't bend but rotate when you extend/contract it.

I started editing the replay when I wanted to untwist my leg and simply relaxed it to rotate on it. After the complete rotation I recorded and switched back to classic and made the final pose.

I've put all the individual parts together to make this replay.

From there on it was almost a piece of cake. I simply had to overwrite my thigh and arm positions with the ones from uke from the replay where I ripped his parts out of my body and it was done.
