The only real protest was an exclamation of "Hey--woah!" and Tony raising his hands as more of a signal to stop advancing than any premeditated deflection. Okay, he supposed Steve deserved points for commitment. In this position, Tony could make Steve's job difficult by kicking his legs and pushing against his shoulder, but to little effect other than making himself more distraught; he was feeling dizzy enough upright, and upside down was like being underwater on Saturn, as far as he could guess. Some really horrible way to have your head exploded, anyway. Which was to say nothing of the upheaval and subsequent pressure against his stomach, making all of that sake and vermouth feel like possibly the most regrettable sequence of decisions he had made in that entire year, and he was dangerously close to tasting them all over again. So he gave a hiccup and one final kick of displeasure before focusing his energy instead on trying to find a more comfortable weight distribution in this new incontestable position. It involved a lot of straining and pushing against Steve's back until that proved just as fruitless, and he had to express all of his frustration by punching Steve in the tailbone. That, at least, must have sucked for Steve.
