Outdoor fun

I met up with a girl who's an occasional fuck buddy to explore a walking track in Darwin.
I'm wearing shorts and a t-shirt and she's in leggings and a baggy t-shirt,
I can see a slight camel toe between her legs as she gets out of the car.
It's the usual hot and humid weather of Darwin's Wet Season so before long we're both hot and sweaty, I keet catching glimpses of her nipples against her top and a little damp patch of sweat between her legs, my own shirt is damp along my back and chest.
We stop for a break and grab a drink of water, I'm standing close to her, she reaches down and grabs my shorts, pulling me closer, kissing me.
I put my hands under her top to find she isn't wearing a bra and hold her firm breasts, rubbing her nipples between my fingers. She pulls on the string on my shorts and they fell down to my ankles, she strokes my cock making it harder and harder.
I put my hand down her pants and am delighted to find she isn't wearing any underwear either. My middle finger slides straight into her wet hole. We play with each other for a few minutes until she gets down on her knees and kisses the tip of my cock, she pulls the foreskin back and takes my entire 7inches in her mouth.
She plays with my balls as she kisses, licks and sucks on my dick, only stopping when the first drops of pre cum leak out.
She stands up as I kneel down, pulling her leggings down as far as her knees. I grab her arse and pull her sweet pussy onto my face, I lick and suck on her pussy until she shudders and moans softly as she cums. I stand up and we kiss she can taste herself on my lips. We pull each other close and she takes my cock in her hand and feeds it into her pussy. It's tight and hot, feels amazing. We move together getting faster and faster, I reach down and play with her clit, she moves my hand up to her mouth and sucks on my fingers and a few seconds later I cum, pumping my load into her. She cums a few seconds later and we hold each other for a minute or two. I pull out and tug her leggings up. She kneels down and licks my cock clean and pulls my shorts up.
We had just finished tidying ourselves up when we heard voices coming along the path, we quickly start walking, my cum leaks from her pussy making a wet patch between her legs as we go back to her car
