Severina busts into Sirius' bedroom with a triamphant smile on her face.
"Not this time, Black." She says smugly.
"Oh, yeah?" Sirius' eyebrow quirks. "What's 'not this time,' Snape?"
Severina places a small muggle clock on the bedside table. Sirius peers at it curiously. "I have set this alarm clock to go off at sunrise." Severina seems proud of herself and wonders why she hadn't thought about this earlier. "There will be no 'morning after' this time."
"There is an alarm clock in my parents' old room," Sirius points out.
"Do you think I would trust anything that belonged to your mother?" Severina scoffs. "It's probably jinxed."
"No arguments there," Sirius says. "But why did you bother with this?"
"The past few weeks have been… irregular." Severina speaks carefully as she unbuttons her shirt. "This… arrangement between us is convenient, but I cannot allow myself to become complacent. This is just sex, Black. Nothing more."
"And 'just sex' can't involve any 'morning after' nonsense" Sirius says.
"You understand, then."
"I understand that you're losing your mind," Sirius says casually. "I don't care if you spend the night. I prefer it, actually. No feelings involved, I just like having a warm body in my bed."
"Shut up." Severina discards her shirt and moves to straddle Sirius' lap. Sirius grins as she tilts his face upward until they're kissing. When they break apart, Severina stares so hard into Sirius' face that he momentarily loses himself in those dark eyes. "This is nothing more than a physical release for our frustrations." She sounds as if she's talking more to herself than to her bedmate. "There is no room for emotions in war."
"Whatever you say, babe," Sirius says, gripping Severina's hips and rolling them onto the bed before Severina can protest to the pet name. "So, doughnuts sound alright for tomorrow, or would you like scones again?"
"Just fuck me, Black!"
"Scones it is."
When dawn rolls around, they're still going at it, their movements lazy after hours of that so-called passion, of fucking and talking and more fucking. The little clock begins to ring like a bell. Sirius is highly amused when Severina grabs it off of the nightstand and tosses it across the room, and the animagus has just enough presence of mind to cast a silencio on it before he's dragged back down by cool hands, a hot mouth and biting teeth.
Severina wakes to the smell of cinnamon a few hours later. She takes a scone and the little clock with her when she leaves. Once outside, she hurls the clock into a trash bin with as much strength as her exhausted body can muster and sighs defeated.
