Unfortunately for Max, 494 still had a refractory period, which, while shorter than the average human male his age, was still there. He didn't pull himself out of the other X5, breathing hard but his body relaxing a little as he studied Max. She was as insatiable in her heat. He wondered if her outside world "boyfriend" that Renfro mentioned would even be able to last if he'd been here instead - somehow he doubted it and he again wondered if she'd even told him about her heat. It wasn't exactly a secret with your fellow X5s, but somehow he doubted an Ordinary would take it so well.
494's hair was slick with sweat; he reached up to push it back and then had the impression he was probably supposed to be doing something other than just waiting to have a go at Max again. It'd be more efficient to save all his energy for just copulation, but then again, Max wasn't exactly a stickler for what was efficient, only what was fun. He bent forward and buried his lips in the crook of her neck, working his way down to her breasts.
