I likes limping suited junk SB

BB is ubernit, here I had him at 6/2, over a small sample tho. Until now he was willing to felt every hand he decided to play. No reads on MP2. I was pretty sure BB had to have a 4 or 33, MP2 has probably some crap like 77. Do I better slowplay,try to keep the pot small and maybe let MP2 donate a few chips or do we aim to felt this?
Its a limped pot, meaning BB could have any 4, 6 ahead of us (counting 33, discounting 44), 6 are dead.
