Roxas walked into the kitchen with his shirt half unbuttoned, a hickey on his neck and a bruised mouth. Riku didn't say anything as he took another bowl out of the cabinet and dumped the remainder of the cereal into it. He then shoved the bowl into Roxas's hands and sat himself down at the table, his cereal still horribly dry even after sprinkling the last three drops of milk onto it. But before he could even take a bite, Roxas had set his bowl down with a clatter, caught Riku's jaw with one hand and tilted it upward as he swooped down.
Riku's knuckles turned white as he let his childhood friend/rival kiss him, desperately, skillfully. The kiss didn't last more than two lifetimes--or rather, two seconds. The door Roxas had come through earlier opened, allowing Tifa Lockhart through, which prompted Roxas to back off. Tifa was wearing less than Roxas, with a trail of hickeys going down her collar, and an equally bruised mouth. But she showed no reaction when she saw them together, Roxas running a finger over Riku's mouth, with a sarcastic "Good morning, Seme."
And Riku finally opened his mouth to make a retort when he saw between Roxas and his shirt, the bruising and wrapped bandages around his waist.
Damn. He wished Roxas would take his issues to someone else next time.
Note: In case you didn't know, in this story, Riku lives in an apartment with five other students--Axel, Cloud, Tifa, Yuna and Paine. Tifa is Roxas's "mother figure" (along with her girlfriend Aerith), but that doesn't stop him from getting into her pants, or spending the night with her when he doesn't want to go home. Riku is Roxas's "emotional support," even though they stopped being friends when they were twelve.
Roxas calls Riku "Seme" sarcastically, because he can't picture anyone girlier than Riku--except for Marluxia, who is so gay he's straight.
Oh, and in this universe, Riku is one year younger than both Roxas and Sora.
Uh, yeah. You'll just have to get details when I write the rest of this story--instead of just short one-shot drabbles for the same universe.
