I'm weak - KK in SB/BB battle

[cbloom]

BB is sort of like a 2+2er, TAG but can be tricky and aggressive. Normally with KK when an Ace hits the flop I'm giving up, but I feel like I just surrender the pot here. In a SB/BB battle he can be calling the continuation on the flop with almost any two. When I check the turn it's asking him to take the pot from me, but betting the turn feels like spewing. Help? In general I find myself raising preflop, betting continuation on the flop, and they just call and when I'm OOP on the turn I just don't know what to do.
