Be warned. No spell or grammar check in here.
This is a rejected part from Rebecca - The Second Time - Discovery. Originally the whole cervix/uterine play bit wasn't there. After Jason splooged but before cleanup in the bathroom this occurred this bit was included. I liked it because it illustrated Rebecca's helplessness when she was de-limbed, and showed that Jason wasn't a saint. This was before I had decided that Jason would have the ability to grow muscles. He was going to be just a guy with giant junk, but things kind of expanded.
Ultimately I felt it went a bit too far for their first time. (But he ends up shoving his hand and arm in her uterus? I know, right?) The whole fingers and toes popping off took things a bit too far too fast with the detachment. Decapitation occurred too soon in the story line with it in this part too. I didn't want to throw everything and the kitchen sink into this one story.
A few ideas might be recycled form this, like how Jason can feel her heart beating against the side of his shaft, I like that one. Using crumpling as a descriptor came back in Rebecca - Surveilled. I think it was better used here, but I liked it too much to not use it elsewhere. Using Rebecca as a cock sheath (sleeve maybe?) may make a reappearance in one form or another.
A scene in the bathroom regarding the cleanup was written too. I might post it later, but there's something in there that hasn't been revealed yet that I might explore. Again, most of that scene was too much too soon.
