You can be greedy, Koby. Tonight, I'm all yours. [He told him he could have his company all night, right? Just them. He grins and, reluctantly, pulls away. But only to slide further up the bed, leaning back on his elbow.]

I think you're wearing too many clothes for all the places I want to kiss and touch you next. [He may not have any experience, but he does have a lot of imagination.]
