Bruce grunts at the sparks and jerks one hand over, up to the other man's face. Shoves his fingers in his mouth. There, you little brat. Obviously the move there is 'my dick', but he's busy, right this second. Maybe later. (Or not. Bruce is sometimes cagey about receiving oral. John isn't the only one with self-worth issues currently in this penthouse.)

With his mouth occupied, Bruce kisses at his jaw instead, and lower, finding that same spot on his shoulder to bite into again, and go about leaving him a significant bruise. Taking his time, as he rocks his hips, sliding their cocks together. Sketching out a plan in his head. Having a precise one with a partner so wily doesn't always work, but it can't hurt to try. It's a nice mental exercise, at least.

Without warning, he sits up, detangling himself and flipping the other man over onto his front (ducking, one hand on John's thigh, appropriate use of combat know-how). He gets one of the magician's hands behind his back, pinning him, pushing him down into the mattress with a firm hand on his head. He digs fingers into his shaggy blond hair and pulls, leaving that there and moving his other hand out of the pin to go lower and deliver a heavy smack to his ass.
