I think the first time they キッス is in City of Ashes when they begin their romantic relationship but other than that they don't go any further with it.
They do キッス in City of Ashes, whilst down in the Seelie Court. Page 160. Though I'm sure they do キッス before that. I just don't know the page, I'm sorry!
No, Clary and Simon do キッス in the Seelie Court. She kisses Simon first and when they find out that that isn't who the クイーン meant, Clary and Jace kiss. But she does キッス Simon then.
Simon and clary kissed at 84 and 25. They did not キッス at 160 because the クイーン interrupted them before they could even do it. The other person who claimed they kissed at 160 is wrong, he/she should've Reread that part again.
