Vex sighs at the gentle sluice of water through her hair. Two things prove quickly to be true. The first, that Percy has clever hands. Different from her brother's (as one would hope), but still dexterous and careful, and they work diligently through her hair and across her scalp. He might not be practiced, but in this case, care almost entirely makes up for experience.

The second: Vex is weak against this kind of attention. The nerves in her scalp tingle pleasantly at his touch as the thick waves of her hair is slowly tamed. She's been known to bully Vax to brush her hair for her, to braid it, because there's something luxurious about having someone else tend her hair that rarely fails to make her melt; she leans back, relaxing into his hand.

That initial sigh is one of many, and accompanied by other soft sounds of pleasure, little moans and hums that she doesn't bother trying to hold in entirely.
