She reluctantly helps

Biting her tongue for a moment, Olivia looks at the man, and then back across the shop. It appears her choices at this point are very limited.

"Fine," she says with a sigh, "I'll show you."

Once again she makes her way back across the store, walking as slowly as possible again to try and keep her trousers up, but feeling them slip occasionally.

You watch closely, and the second time they slip you make sure the man notices, his eyes, practically glued to her arse the rest of the journey, and neither of you are really listening as she explains the difference in graphics cards.

When they finally reach the shelf she reluctantly picks up one, her trousers slipping again with only one hand holding them up. "Basically," she continues, "this one is the most popular."

"And... what about that one?" the man asks, pointing at another, particularly expensive model on the top shelf.
