69 in the car

"As I said", she says, as she carelessly throws her skirt aside. "I´m not just here to please you, you seem to have a full flat of girls willing to do just that. I´m expecting more of a trade-off."
You smile at her justification, but you dont complain as she slowly gets into position.
Her legs go past each side of your head, and you wrap your arms around her waist. Then she lowers her head back and sucks you off again. The feeling is indescribable.
Then, you slowly pull her waist closer to you, until your head is right below her vagina. She smells like victory, warmth. Then you return your favor.

You are fully aware that someone else could pull up to the parking lot, perhaps another couple, and see the two of you as you pleased each other, halfway naked, only focussed on the other ones pleasure. But the idea just exites you more.
Athenas pussy tastes amazing, and you realize that you wont last long. The exitement of being here, doing what you did essentially on top of the city, for anyone to see, and Athenas masterful work on top of that is enough for you to almost just blow your load right now.
One hand of hers holds your dick in position as the other cups your balls, gently playing with them, squeezing them. Sometimes she removes her head from your dick to catch her breath and as she jerks you off you hear her moan because of your tongue, feel the waves of pleasure rocking her body. Then she lowers her head and continues.
