This is Raph/Leo. In my world, Leo is the youngest. I haven't written written anything TMNT in a LONG time. So please be nice.
"Raph..." He whispered, wrapping his arms tighter around the older turtle. He didn't know what they were doing right now. He only knew that he didn't want it to stop.
"Shh, Leo..." He whispered back. He kissed Leo deeply before lowering the younger down onto the soft bed beneath them. He knew that Leo was a virgin and wasn't for such a big step. Especially they weren't exactly together...
For some years now Raph had been pining after him. He had always felt over-protective of the blue-maked turtle and it wasn't until recently that he had figured out why. Up until today though, he had been suppressing his feelings.
"I'm not ready..." Leo's voice brought his back to reality. Raph spoke his head and smiled at his baby brother.
Technically… the brothers weren't related by blood so even if he and Leo did start dating it wouldn't considered incest.
"I know, Leo. I'm not stupid. At least not enough to do that right now." Raph smiled. "I want to take you out first. Anywhere you want."
Leo smiled then quickly frowned a few seconds later.
"What's wrong, baby?" Raph asked as he adjusted his position so he could pull Leo into his arms.
"I love you, Raphie... a lot. But… what about the others? Master Splinter? April and Casey?"
Raph softly kissed Leo's temple before replying. "Don't worry about that now. We'll figure it out in the morning."
"But Raph..." Raph quickly but softly kissed Leo to stop him from rambling. He gently cupped Leo's cheek.
"Stop worrying so much, okay?" He hated it when Leo was worried. He tended to shut everyone out when he was. "I promise, we'll figure it out. Now, get some sleep."
Leo nodded before snuggling deeper into Raph's warm body. "Goodnight, Raphie… I love you."
"Night, Leo. I love you too."
So much.
