Up in the attic of a Luthor castle, there were many odd things.  There was one room that Clark loved in particular.  In that room, Lex had stored mementos of his childhood; things he'd never done but had always wanted to.  Clark had played with Lex in this room many a time.  And as they grew, so too did their games. 

Riding the white horse of the carousel, Lex had come, sucked to orgasm by a bondage-clad Clark.  Now they were atop the horse together, galloping away upon the dreams to their future.  Clark's strength lifted Lex up and down upon his lap, while Lex leaned back against the pole.  The motion, Clark rocking into Lex, Lex raising and falling on him... it was all Lex's fantasies grown up.

Clark's eyes were closed, his mouth open as he thrust into Lex.  Somehow, he kept his seat on the wooden horse.  Lex's grip was tight on Clark's neck, holding himself in balance, knowing he couldn't hurtClark and he watched him.  Watched the ecstasy on Clark's face, watched the pleasure ripple through his body.  Listened to the moans and harsh breaths. 

And he knew that he loved him.
