This is the prompt story that got me thinking about writing a poly BBStarRae story ^_^

Whatever Raven expected to see when she walked into the common room, it certainly wasn't what she did see: Starfire, locking lips with Beast Boy. When they separated, he looked guiltily at Raven, fearful he had damaged what he hoped was a burgeoning romantic attraction between the pair. For her part, Raven felt it as well, but right now she felt one of the uglier sides of affection: jealousy.

"Rae! It isn't what you think! Star's been hounding me to learn Swahili all week and I gave in and… yeah," he ended lamely, largely because he had enjoyed the kiss more than he thought. Starfire blushed as she smiled sheepishly.

"It is the truth, Raven. The kiss was intended purely for language transfer and any pleasure we derived from it it entirely coincidental," she insisted. Raven only raised an accusing eyebrow while Beast Boy face-palmed. Raven sighed, knowing her friends were innocent. Dumb… but innocent. Still, even if she couldn't get mad, it didn't mean she couldn't get even.

"Hey Starfire. You ever wanted to learn latin? Ancient greek? Sumerian? Azarathian?" Raven asked. Starfire clapped her hands together and smiled broadly.

"No! But I do now, very very much!" she sang. Raven stepped forward and put her hands either side of Starfire's face, her thumb gently rubbing her cheek. With lidded eyes and a ghost of a smile, Raven leaned in and slowly pressed her lips to Starfire's. Her right hand slowly traveled down Starfire's arm before moving round to her back and splaying out, pulling her nearer. Her left hand moved up and delicately ran through Starfire's hair to her shoulder before resting there. Their mouths hadn't opened but Raven had applied rather more pressure than Beast Boy had, and when the kiss ended, Raven's right hand returned to Starfire's face and just barely caressed her jaw with her fingers before Raven stepped back.

"Did you get all that, Star?" Raven asked, smiling. Starfire, red-faced and arms limp, blinked at her.

"Ummmmmm…"

"I'll take that as a yes," Raven said, resuming her journey to the couch but aiming a victorious smirk at Beast Boy, who stood wearing a slightly more envious shade of green on his skin.

The smirk had two meanings and both were clear: first, whatever this had been, Raven had won; second, if he played his cards right, maybe Raven would kiss him like that.

He hoped so.
