Customer Service - Short Story

His friends couldn't believe it when Dave applied to work at the convenience store, especially not since the position was on the night shift. There was no other choice open to him though, the art course he was on had turned out to be far more expensive than he'd planned on, with most of his money eaten up with the course fees and art supplies with very little left over for his rents and transport costs.

When he saw the job posting he'd not eaten properly for two days and the decision was made straight away. It was surprisingly well paid too, even if his friends relentlessly referred to the night shift bonus as 'danger money'. Doing four weekday shifts and one weekend every fortnight he was earning enough to easily cover his bills and still have some money to treat himself with. And then there were the fringe benefits.

As he leant across the counter, flicking through one of the comic books which had been gathering dust on the display stack the door beeped and slid open, admitting the two girls. The twins were regulars and as they giggled their way down between the shelves Dave couldn't help but let his eyes wander up from the colourfully drawn pages to watch their well-formed posteriors jiggling beneath the incredibly short skirts the two girls were not quite wearing. Occasionally, as they stopped to inspect a product, leaning down to pluck something from the lower shelves, Dave would catch a glimpse of tanned buttock, but never a flash of panty and he could feel his briefs tightening before he finally looked away, blushing uncomfortably at the stolen moment.

Dave was just about to turn the page to find out what the monstrosity was planning to do to her when the girls returned, laying their choices on the counter in front of him.

"Hi Dave." The twins said in unison, their voices cute and bubbly. They were both fluttering their eyelashes at him as he reached for the products and began to scan them through the till. "Hi girls. Having fun tonight?" He asked casually. For some reason this amused the twins no end and they both burst into a fit of giggles, their own buxom chests bouncing inside their tight tops in a way which Dave couldn't help but watch.

"We've got plans for tonight which should be loads of fun." One of the girls replied, picking a lollipop from the nearby display and popping it into her mouth, licking it with her tongue suggestively as she did. Dave tried to decide if it was Emily or Jen, but he could never tell the girls apart. Looking down at the selection of products he smiled over at her. "Whipped cream, maple syrup, condoms... Certainly seems like you're well prepared."

Suddenly leaning forwards, her arms braced against her side, squishing her breasts together so they almost popped out of her top
