Although you don't get to see anything, the sound is a turn-on.

[Kev]

It only shows her face but it looks as though she's having an orgasm. I'm not sure if it's 100% real (she's really getting licked or done), or if she's masturbating, or if it's just an act altogether. If I knew for certain it was real, it'd sure enough be a turn-on then.

Only thing is she's not sweating...

Uhh, why would she have to be sweating?

I figured she would when having an orgasm. Even I sweat (a little) when jacking off.

That's probably nervous excitement at the thought of the park warden catching you.
