The かぎ here (completed かぎたい) is actually 嗅ぎたい which is desire form of 嗅ぐ, meaning to smell/sniff. So more correctly it's「もっと匂い嗅ぎたいんでしょ?」translated to "you want to smell (my odor) more don't you?" But I'm bad at actually localizing sentences to flow well in English, so yours is good.

Thanks for clarifying that, it's good to know I'm not getting things too wrong so far and I'm guessing knowing about the desire form of verbs is something I'll probably need with this particular manga.
