Just reserving this spot. It's probably about a pair of sworn enemies forced to marry and pretend to be a loving couple in front of their elders, only for their fake affection to accidentally turn real.
At first:
In front of their elders, they were a perfect, loving couple. Behind their elders' backs, they couldn't stand the sight of each other and could hardly keep from rolling their eyes.
Bottom: If you didn't look so good, I'd have thrown up right after kissing you at our wedding.
Top: If you didn't look so good, I wouldn't have been able to bring myself to kiss you.
Later:
After a wild round in bed, the top held the bottom in his arms, while the bottom nestled against his chest.
Bottom (tilting his head to kiss the top's lips, deliberately teasing him): Want to go again?
Top (flipping him onto his back and pinning him down, kissing him until he can't breathe as he pounds into him)
Theme: Still thinking about it.
