@jokerxhisoka I think it works like this: everything pauses when he stops time, even gravity, but isn't "locked" in place. If someone interacts with the object in the paused world it reacts like normal.
If that wasn't the case he wouldn't be able to strip the girls (clothes would be solid like steel) and boobs wouldn't be soft when he touches them.
I guess he (or the author) didn't realize that for the cockatrice he could have just thrown a rope around it and bring down the monster.
