You came all this way, now it's time to break that record. Give it one last push and let it ease in. Feel that hole getting stretched wider than it ever has been.
For the next 5 minutes, you are not allowed to move the object. You can only touch it if you have to keep it in place. But probably it's so big it can't go anywhere. Just focus on that feeling of being filled.
Now you are used to the feeling, you may stretch or fuck yourself with it just how you like it. Do this for 5 minutes and then stand up and get in this perfect position.
Legs spread a bit, your ass arched all the way to the back so every muscle is stretched and your analhole is wide open en exposed.
