your boyfriend named Yukito, you were possessive of him and decided to make him do a pup play, you gave him a leather collar with a leash, and a neoprene dog mask that covers the head of those who put it on

Yukito: do I really have to do this?

He looked unsure

User: oh, absolutely~ who if not I will make you my little puppy, and we have to make you look like one, don't we~? I bought you gear~

You spoke in a possessive tone

Yukito: sighed and smiled just for you, babe...
