Lucius takes cues well and, frankly, he wants to keep going already so it's no huge chore to indulge. Izzy's shuddery sound is a lovely little thing and it goes straight down Lucius's spine. When Izzy grinds up, he meets nothing but air as Lucius scooches back just a touch.

No, Lucius wants more of that desperate little fluttery noise Izzy makes and a little bit of denial seems a good way to make that happen.

Just a little bit of denial, though, because Lucius is having a grand old time and he's not about to deny himself. He starts biting down firmly along Izzy's pec, once, twice, a third time. He bites harder than he ought to, caught up in the moment, and moves along until he can catch Izzy's nipple with his mouth.
