Charlie and Oliver's first kiss had been after Quidditch practice on a very cold and windy day.
Their second kiss had been on the way back to Gryffindor tower. It had been far more passion filled than the first and left Oliver gasping for breath and the beginnings of bruises where he'd been pushed against the wall.
Their third kiss had been on Oliver's bed with a silencing charm around the bed to stop Percy from hearing them. The kiss was slower and more gentle than the ones before.
That night many more followed.
Percy caught them having their 46th kiss weeks later.
