hey becca, where in singapore got these sort of saunas?
Anyhow, just to share my experience
The most memorable one I had was with my girlfriend... we were 19 then, went to Macritchie and got really horny - it was only 8pm and we were sitting on the bench, along the walking path, just next to a telephone booth... we were kissing and I started putting my hand into her blouse and into her bra and feeling up her breasts, we stood up and continued making up next to the walking path, leaning against the phone booth.
I didn't know what made me do it but I just lifted her dress off her, and she was standing in her bra and panties; I told her 'take it all off' and I was amazed when she stripped totally naked in the middle of the path. I was still wearing my berms and t-shirt. She pushed me against the phone booth and unzipped my trousers and started to suck me. I felt bad that she was naked and I wasn't so started taking off my t-shirt while she was sucking me and dropped my underwear and shorts to the floor.
We were now both stark naked and anyone who was jogging/walking past would have seen us... but I guess we were young, foolish and just didn't care. haha. I made her half-squat and lean against the phone booth while I licked her pussy.
We got a little scared after a while and put on our clothes.. as we were walking off, we heard some rustling in the bushes and the footsteps of someone running off!
I guess we were being watched after all!
