You and your toy have a lot of time to make up. Perhaps that pace could be quickened by using multiple objects simultaneously. However it's done, I think the key word should be "Multiples" ;)
It seems to me that since you have been away, it's fuckholes prob will not be used to being stretched that much right away. Instead, consider starting with regular sized objects and increasing the size till you get to something that will open it's hole wider than she ever imagined possible. Unless kept forced open, Everything will return to normal when you are done. Use lots of lube!
