Hi, this is what my wife's mules now look like after becoming my cum dumpsters with strictly no cleaning.
I had the shoes (her ones, the cum dumpsters) stashed in a plastic bag in the guest room wardrobe, but recently the wife discovered them whilst retrieving the baby bathtub. I shouted to her to let me go and fetch it but she had gone ahead already, oops.
The next day I found the bag of shoes at the bottom of her shoe cupboard in our bedroom. She must have suspected what was happening as she wouldn't have possibly have put the shoes in the guest room wardrobe herself, but anyway she didn't say anything to me at all. I suspect she did not look closely inside the bag else she would have seen that the mules were badly covered in cum.
Since she has not worn those mules for a long time - she had them stored in the original Office shoebox in the very bottom of the shoe cupboard, basically inaccessible, it is a good thing they are at least now easily accessible. Meanwhile I have removed the cum dumpster shoes from the bag and put the newer pair there instead, so in the event she does look inside the bag she won't see the cum dumpsters. Next I shall work on getting her to wear them again when we fuck, I miss that..
