And that was exactly what she had warned him about, wasn't it. It wasn't even the most risqué thing in that pile either, she was sure. She had some pretty sassy stuff. It implied that she got laid far more often than was the case, but, hey... there was something sexy and fun about having something discreetly lacy under a sweatshirt or jeans.
Though, Ninkasi had to admit that the look on Kratos' face was priceless. She was trying really hard not to laugh. “So,” she said, grinning but definitely biting back a laugh, “is that going to go in one of the piles you've got started or should I get up and leave the two of you alone?” In emphasis she gestured between him and her undergarment in his hand.
If he didn't expect her to tease him then he didn't know her well at all. She gave him fair warning and he was the one digging though her dirty laundry.
