This was something I drew nearly two years ago. It features Cadance swallowing her husband who developed a secret vore fetish that his wife eventually found out about so she decided to put it to the test while relaxing him further with hypnosis. She’ll spit him back out later. There are three more of these featuring the other three princesses swallowing someone specific (excluding Celestia who swallows several of her subjects)  
I don’t draw a lot of vore, but still wanted to show it off here to those who enjoy it.
