Near the bubble, hitting monsters

[montybear]

Okay, similar situation happened to me twice last night. One is a 33 1-table, the other is a 33 2-table SNG. Four and five people left, moderate blinds (as compared to stacks), all roughly equal stacks. In the CO, I pick up TT and JJ. Both times I raise 3BB, as everyone has >10BB left. Both times the button calls, one time one of the blinds also calls.

I hit a set of Jacks on a J rag rag flop, and I hit quad tens in the other case. I almost always make continuation bets when I raise preflop, so anyone paying attention should/would notice if I check these flops.
Both times I tried to lead out with a 1/4 of pot bets, hoping that someone reads that for weakness. Is this wrong? But no, both times everyone folds.
I really feel that checking just looks too suspicious. Should I be giving as many free cards as it takes to get someone to bet? On the quads, the blind had been reraising all in a lot when someone showed weakness.
Looking for a better way to play these hands.
