snapesgirl62 prompted me with Severus/Regulus: rules, brandy, celebration.
An Unexpected Victory (PG; Severus/Regulus; 100 words)
"There are no rules against drinking brandy in the common room," Regulus tells Severus, handing him a glass, "and this is a celebration."

"Ah, but the best is yet to come."
"What are we celebrating?"
Grinning, Regulus leans forward to whisper, "The loss of my virginity."

"It's you."
"What?"
"That is, if you want-"
Severus kisses Regulus before he can change his mind.
