Continue the normal, usually quick way.

You tell them that you should all go the normal way. It's quicker, usually, but if there's construction that'll be a problem. Though as you begin to relax, you feel her fingers creep up your inner thigh. They move closer and closer to your sensitive spot, causing you to squirm awkwardly on her lap. At least the two of you are still covered by the blanket, so the rest couldn't see under your skirt... but this was horrible in its own right

She starts to tease you slowly. Very slowly. Her fingers barely press against the edges of your labia, simply causing you to flush red and softly sigh. You curse her skilled fingers. She seems to be able to make anything feel amazing.

Soon you would arrive at McDonald's though, and you could rest. Surely she wouldn't do this out in the open. She speeds up slightly... Oh. You moan quietly.

But, you see your destination, and as the vehicle pulls into the parking lot, Alison stops before you reach your orgasm.

"Almost there!" shouts Troy. You're left hanging on the edge, just sitting there. What can you do? You're at her mercy. You can't even ask her to finish you off.

"You sure you need that blanket?" asks Roger suddenly.

You're clearly sweating, and your face is burning. Alison tosses the blanket to the side, fixing your rustled hair and patting down your skirt. Thankfully, it was pulled down when your body was revealed.

"Sorry, girlie. I didn't realise how hot you were. You should have said something..." teases Alison.

At long last, you park in the McDonald's parking lot.

You're the first to step out of the truck, but your legs immediately give out. You grab onto the side of the vehicle as you nearly fall. Alison hops out behind you, patting you lightly on the bum as she moves past and towards the boys, and you follow soon behind.

The panties. You completely forgot about the original problem, and with Alison's meddling, you're now nearly orgasming with each and every step you take. Your labia burns with pleasure at the feeling of the fabric's rubbing. All you need to do for now is to make it to a table without succumbing to temptation.

"Are you coming, Jane? Please come..." She winks.

Stepping carefully, you walk inside. As soon as you enter, you make a mad dash for the closest four-person booth and sit down, exclaiming to your friends to just get you a burger, just as a snack. You aren't very hungry. The boys look at you strangely but accept, moving up to the counter to order with Alison.

You're left alone at last, but you want to orgasm so badly.
