Not a couple
A/N this takes place right after Robin comes home to find the Titans in his costume.
Raven fell off the couch, scrambling towards her room. The others went to change, too. She ripped off Robin's cape, leaving it on the ground. She was so embarrassed, so so embarrassed. Robin had come home, and heard her say the mask made her feel cool. She slid into her room, slamming the door. Robin would never let her live this down. He would tease her for eternity. She was pulling her arm out of the shirt when someone knocked. She pulled it back in and answered the door. Great. It was Robin. He was smiling cockily, obviously trying not to laugh. Raven blushed, crossing her arms over her chest. "What?" She snapped, glaring at him. "Well, Raven, if the mask makes you feel so cool, why don't you keep it?" Robin laughed, making Raven hiss. She tore off the mask and threw it at him. Robin calmed himself, looking at the mask. He raised a brow under his mask, staring at her. "You know Rae, you do look kinda cute in my costume." Raven blushed harder, levitating a cloak to cover herself up. "Shut up." She pulled on the cloak, pulling up the hood. He walked into her room, sitting at her desk. She glared. "What do you think you're doing?" Robin only smiled. "I'm sitting." Raven rolled her eyes. "Are you done laughing?" He nodded, getting up and walking towards her. He stood behind her, hands on her shoulders. "Robin....." Yes, it was true, they had feelings for each other, but they weren't officially dating yet. Robin had kissed her a few times, but never anywhere other than her lips. He leaned down, kissing her neck. "What?" He asked, stopping his journey. "I'm mad at you."
"Why?"
"You made fun of me, idiot."
"So? I said you looked cute."
"I don't care."
"You know, if you like my outfit so much, you can have it."
"Stop teasing me." Her words were forceful, but she didn't make an attempt to move. Robin continued to kiss her neck, moving to her collarbone. His tongue moved across her skin, making her shiver. "I do like you Rae, a lot." She nodded. "Yeah, you told me."
"I think you should wear this more often."
"Why's that, Boy Blunder?"
"I like seeing my things you."
"Yeah, I can tell, Bird Boy." She rolled her eyes, but allowed him to keep going. She did really like his costume, even if it made her look like a traffic light. Maybe that's what made Robin so touchy? Well, she could definitely deal with it. Especially if it meant him doing this.
