[An indignant heat spreads through Gon's cheeks as he imagines Killua playing so roughly that he leaves a bruise on him somewhere. Or even better, a hickey or love bite. As always, his imagination is somewhat too vivid for his own good. With the soap, the shower head rinses away such thoughts.]

Hey Killua? Next time, I, um...want you to leave a mark on me, okay?

[When Killua's done with the shower head, Gon takes it and rinses him off before grabbing some of that apple scented soap and applying it to Killua's chest. Gon turns him around to face the mirror and gets behind him, his breath on Killua's neck as he wraps his arms around him and spreads the suds down his torso.

Gon kisses his neck.]

See that? That's mine.
