Disclaimer: Okay, seriously, if Yu-Gi-Oh belonged to me, do you REALLY think I'd be writing something like this? Do you? Yeah, that's what I thought.
Yuugi did not know where the idea had come from. He was very sure he was definitely going to hell for it, but it was just so addicting.
He moaned as he rubbed the Millennium Puzzle against the bulge in his pants again. It felt so good!
Yami would probably scream if he knew. After all, this puzzle was their only link. Their connection. It had granted him friends and Yami, somebody who understood him. And Yuugi was rubbing the very same item against his crotch in such a degrading way. But then, maybe that was why he used it for masturbation.
He could feel his release coming soon, and he started going harder and panting. The puzzle was so much better than his hand.
"Yes…yes…yes!" He almost screamed as he came, his boxers feeling suddenly very sticky and grossly uncomfortable.
Out of breath, he smiled at the puzzle in his hand before kissing one of its golden sides with affection.
It was definitely one of his most cherished things.
Notes: I was watching season 0 with a friend and I pointed out how it's always the puzzle Yuugi worries about. Even before he knew Yami was there. So I said "People say how obvious Yami/Yuugi is, but Yuugi is obviously in love with the Millennium Puzzle! It's the true puzzleshipping!" The joke has evolved into this. There will be Yami/Millennium Puzzle and then Yuugi/Millennium Puzzle/Yami. I'm just doing this for fun. Nothing more.
