[Action]
[One minute Sora's just glad that Riku's back, that Riku's okay, that they're okay and the next.... the next... Sora can barely even process what's happening. Just the soft-warm press against his mouth and then Riku's hasty retreat]
[Its only because Sora's stil in hyper-attention mode from his wait for Riku that he's able to react to quickly, grabbing onto Riku's hair and then tackling him to the floor.]
[But just to make SURE that Riku's not going anywhere, he lays down on top of his captured best friend and traps Riku's arms down. Even if Riku DOES managed to get to his feet, he's going to have Sora pigging backing along]
