Just found two places.
Here's a link for better navigation.
Fort Canning CP just opp Liang Court, it was a quiet yet sexciting place to bonk. Having said that, couldn't really do anything sexradically sexciting. Damn, even saw a gay couple making out too.

Just as you take exit 15 on the PIE towards CTE, there's like a bay or something for temporary stopover. Bonking there was FUCKING AWESOME. Even got her out of the car, walk over to the driver side, squat on her 3-inch heels and blow me. Subsequently, i got out of the driver seat, got her pinning against the door frame, got my Thrusty Piston @ Full Throttle.
