The two of them could count on one hand how many times they had these kinds of conversations. Draco had been the one Blaise had drunkenly confessed to about his first time with some older Slytherin in their fifth year. Since then, he hadn't been able to shut the wizard up about every conquest he would see fit to brag about. For his part, Draco would push Blaise and he would push right back for rare truths and something in the air told Draco this would be one of those times, hence the strengthening of his Silencing Charms.
