(drift fusion anon here!) i ment steven universe kind of fusion, sorry that i was unclear
"You want to try what, my lord?" You ask as you look at Drift before you. The mech smiles and carefully takes your hand like you were made of finest glass.
"I would like to try fusing with you." He said and you blinked. Why would your lord want to fuse with little plain pearl like you?
"My lord-"
"Please Pearl." Drift interrupted you with a gentle tap on the shoulder, "Call me Drift."
How bold! To call your lord that your Diamond had given you to by his name? But if he insisted then who were you to deny his orders?
"Drift...?" The name sounded almost foreign for you to say out loud.
"Why would you want to fuse with me? Certainly you would be more pleased with a Jasper or a Sapphire?"
"But I want to fuse with you." He said and you frowned. He continued, "When you told me how amazing it is to fuse with someone you care about, I knew I wanted to experience that with you."
"But my lo- Drift!" You quickly corrected yourself. "I'm just a pearl, meant to serve you."
"You're my friend and I want to give you freedom to do what you want." Drift said, "So if you don't want to fuse with me then it's alright."
"It's..." You frowned, "It's not like I don't want to. I'm... Scared."
A silence fell between you two... Until Drift leaned in and pecked the top of your head.
"Pearl, as long as I keep being, I want you to feel free. I won't force you or pressure you, I just want to know you better."
You swallowed. No one had been so kind to you as Drift was. The mech looked at you with such a tender blue optics so you swallowed your fears and took his hand.
"Alright. Let's try it."
Drift's smile rivaled the sun and he took your hand and gently lead you and you gracefully followed his each twist and twirl until the light devoured you two and you two became one.
"Oh, wow...!" You and Drift gasped together as you looked down on your dark black from.
"What are we exactly...?" You both wondered and just like magic, the answer came to you. You had turned into black goldstone. A fitting gem for a mech as kind as Drift and dark as your skin.
"How do you feel?" You asked from yourself and the answer was quick. "Like I'm one with my best friend. And I love it."
You and Drift, now Goldstone smiled.
