Obviously Bruce and Clark even as enemies are already very much into totally platonic chest petting. Tell me how that evolves as they get to work together, know, fall and pine for the other. Do friendly claps on the shoulder last a little too long? Tend to involve a meaningless brush of the fingers on the chest?

How do they ever progress from that to sex and foreplay that involves rubbing and pinching of the nipples through shirts and whatever else your mind may conjure?
