Bruce lets it happen, so it's more of an oof than it might be otherwise, but he wouldn't have it any other way. There's a fine line to walk in between underestimating Clark - who is still a huge guy very much capable of doing damage - and going too aggressive with it.

Which becomes: half a lesson, half messing around, reminiscent both of sparring in the practice room at the lake house and shoving each other around in bed. Bruce gets him a little too hard and has him land with his own hand behind Clark's head, not wanting to give him a concussion, even though it means they end up hilariously tangled together on the floor for no good reason.

Bruce squeezes his side, barely below his ribcage, thumb pressing into the would-be-soft tummy area if not for his thirty-pack, or whatever it is, which is still very Man of Steel even without the powers. A ticklish zone. Threatening.
