Busted Flush Draw & Ass Ended Straight

Lately, bets are flying all over the tables. Yesterday's session, got me out of a slump I've been having for the past few days.

PokerStars No-Limit Hold'em, $0.25 BB (3 handed) - Poker-Stars Converter Tool from FlopTurnRiver.com

Button ($15.50)
SB ($33.75)
Hero (BB) ($22.60)




Preflop: Hero is BB with J, 10
Button raises to $0.50, SB calls $0.40, Hero calls $0.25
Flop: ($1.50) 9, 8, 7 (3 players)
SB checks, Hero checks, Button bets $1.25, SB calls $1.25, Hero calls $1.25
Turn: ($5.25) 6 (3 players)
SB checks, Hero checks, Button bets $2.50, SB raises to $6, Hero raises to $20.85 (All-In), Button calls $11.25 (All-In), SB calls $14.85
River: ($60.70) 2 (3 players, 2 all-in)
Total pot: $60.70 | Rake: $1

Results:
Button mucked 9, A (one pair, nines).
SB had 10, K (straight, ten high).
Hero had J, 10 (straight, Jack high).

Outcome: Hero won $59.70

I made the HUGE overbet for a couple of reasons: to protect against the flush draw/at the same time making it expensive if they want to try to draw out on me; I was hoping the SB had a 10 and would have to call.
