“Oh, erm…” Sirius stalled, waiting for the Muggle to wash his hands and leave. “It’s a condom machine.”

Severus shot him his best ’are you actually that stupid or is the sole purpose of your existence to exasperate me?’ look.

“Muggles can’t use magic for sex protection.” The look didn’t falter, so he continued. “It’s like a sock for your dick.”

Severus blinked.

“Here, I’ll show you.” He shoved some Muggle money into the slot, holding up the foil packet.

“Those poor Muggle women.” Severus sighed.
