The prompt for this chapter was "Smell of Hot Chocolate", thanks Ginnyvos!
When they decided to head home it was late. Not late enough to enjoy deserted streets (it was Halloween after all) but still quiet enough to enjoy some illusion of privacy. Sirius had had quite a few drinks and was a bit past tipsy, whereas Remus was just quite tired and ready to curl up in bed. They were walking down the road, bumping into each other every now and then, when Remus suddenly stopped, grabbing Sirius by the arm. He stuck his nose a bit further in the air and sniffed audibly.
"Sirius, do you smell that?" he asks, drawing another deep breath.
"I smell nothing, apart from, you know, general Muggle-London smell."
Remus knew exactly what Sirius meant. Muggle-London always had this undertone of exhaust fumes, lots of people and a whiff of garbage, which somehow did smell different from the garbage in Diagon Alley or other wizarding places. With his keener sense of smell, Remus always had to get used to it in the first half hour of changing sides. Now, however, he was smelling something way nicer than car fumes. "No, that's not what I mean, come on, follow me."
He grabbed Sirius by the hand this time, and started walking fast, dragging Sirius along. It wasn't very long before he could see what he had smelled two streets away; a street cart that was using Halloween to gain some extra profit by selling one of Remus' favourite things in this world: hot chocolate. From what he could smell it was even good hot chocolate, made with real chocolate, and he also spotted a canister of whipped cream.
"Two large ones with cream, please," Remus requested from the vendor, digging in his pockets for some pounds. He didn't even need to ask if Sirius wanted one as well, the look on his face once he had smelled the chocolate too had been obvious enough.
Not long after, they both had their hands wrapped around warm paper cups of chocolatey goodness. They walked along until they came by a lone bench. They both sat down on the back of the bench, because everyone knew the seats were too dirty to sit on, with all those rude people putting their feet on them. Remus took a cautious sip of his drink, when he heard Sirius cursing next to him.
"Why the hell would they make these drinks so hot? I think I just burned my tongue." Sirius stuck out his tongue and was apparently trying to see if it had sustained any damage. It was such a funny sight that it caused Remus to laugh, which resulted in an unamused glare from Sirius.
"Not funny," he deadpanned. The crinkles around his eyes betrayed his mood, though, and Remus gestured to his mouth.
"You managed to get another foamy moustache with your greedy drinking habits." Remus swiped a little of the cream with his finger and put it in his mouth. "You're lucky I like whipped cream, though," he said with a grin, and he kissed the other side of Sirius' upper lip, where even more of the cream was located.
By the time Remus had made certain he had gotten all the cream off, their drinks had cooled to a nice drinking temperature, and the fake blood on Sirius' face had somehow migrated to the right side as well. But, since they were heading home anyway, he wasn't about to complain about Remus' sloppy cleaning methods.
