Dealt to Hero: 2♦ 6♣ K♦ A♠ 9♦ A♣

So Button is Vpip 70, straddling every hand to 2bb and not overly aggressive, so I decided to just call and see flop cheaply with my average Aces. I flop trips and decide to stab halfpot, as he is going to come along with any straight draw anyways. Turn brings me a boat and I again go for halfpot and he calls. River brings a straight and also upgrades my boat, so I go for 33%, to get paid by straight and weaker hands but he now goes over the top and shoves. At this point I am thinking he must have been slowplaying TT, while KK is extremely unlikely as I also block it, T9 would shove Turn. But at the same time we are dealing with a donk so you never know. My question here is, do we ever fold this hand against a fish or is it a snapcall 100% of the time?
