A woman selling burgers.

You both peer at the entrance to the lay-by and see a red pickup approaching. As it comes into full view from behind the trees, you see that it is towing a large white trailer with a hatch in the side. Written in big blue letters on the side of the trailer is "Becky's Burgers: Burgers Hot Dogs Refreshments". You glance at Jo. She looks a little embarrassed, very flushed and sweaty, but doesn't look like she's planning on going anywhere just yet.

The van pulls up across from you and the driver switches off the engine. The door opens and a woman climbs out, presumably Becky. She's in her early twenties, with long brunette hair. She's casually dressed in a low cut black vest (you notice she's not wearing a bra), jeans and flip flops. She glances over at you.

"Morning guys. Be with you in a sec." As she says this, she walks into the van and after a few seconds opens the hatch. She then climbs out and strolls over you both. As she approaches you cannot help but eye her up. She's an attractive, light skinned woman, curvy without being overweight. Most of her weight seems to be carried around in her top, where her massive, pendulous breasts swing gently. She has a large, welcoming smile. As she approaches, you can see that she has a small stud in her nose. Despite the fact that you have recently cum, your cock starts to stir as you realise how close Becky came to seeing you fucking Jo.

"Sorry about that. Had to get set up for the lunchtime rush. A lot of lorry drivers stop off here. It's about to get pretty busy. I'm Becky, by the way."

You hesitate for a second, then realise that you should probably speak. However, Jo speaks first. "Hi Becky, I'm Jo, and this is John. We were just passing through and ran into some car troubles. It seems our exhaust has fallen off."

Becky smiles at Jo, then at you. "Well, you picked a good time for it. As I said, it can get pretty busy here. I like it here at this time of day. If you ignore the traffic, it's kind of peaceful. You need to use a phone or anything?"

"It's OK," you say, "We've already called the recovery people. They won't be here for another hour though."

"Great," she says sarcastically, rolling her eyes. "Hey, did you want a burger? They're pretty good. Tell you what, they're on the house. Sort of an early bird special."

Your stomach rumbles as you remember you still haven't eaten today. "Sure. I'm starving," you say.

The three of you start to walk to the van. Becky turns back to speak to you both. "I'll make you a - hang on, I think you dropped something." She walks back a few paces and picks up something small and black off the floor. As she holds it up, and the three of you simultaneously realise what it is: Jo's thong.
