This is the very thing that Bruce had asked for, and Clark's nearly killed him with heat vision, and he's trapped beneath him, completely at his mercy while the Kryptonian has some out-of-body euphoric experience— and yet there's still something so sweet-natured about him. I love you. Tell me. Bruce even thinks if he said no, Clark would stop, and it'd be fine.

Except, it wouldn't be fine for Bruce.

"I want you to fuck me, Clark."

His voice is steadier than it has any right to be. An important conviction, acting your boyfriend to go beyond safe and sane and getting off on it so powerfully. Bruce is lucky that his libido will let him enjoy it for real, too, even though he's not thinking about that right now. All he's thinking of is Clark. No room for anything else.

"I need you to."

Harder to say the other thing. His fingers curl around Clark's hands as best they can.
