I would say either fold (because it's a crappy AAxx) or reraise and then autopush. If you think your villain is doing this with KK or QQ and no one else will call, then i think you have an easy reraise.

Of course, in theory, if more people play then you have less of a chance to win, but run the numbers on total EV vs 3 players. It is probably still +EV.

Also, this is your 2nd hand you say? If you want to play earlier in position, why not buy in for the minimum until the button gets to you? If you have 20bb instead of 50bb, this hand becomes a lot easier to play.
