"Fuck!" Remus whimpered, bracing his hands against the headboard as Sirius snapped his hips harder.

He'd lost count of the number of time they had fucked that week. It was only Tuesday.

Ever since they'd had a conversation about trying for a baby it was like there wasn't a single thing Sirius could do that would turn Remus off. Whether it was Sirius teaching Defence, or directing a lost student, or going over a joint lesson plan with Remus so they could combine Defence with Care of Magical Creatures, all of it seemed to get Remus going. Like as soon as he'd made the choice to have a child his biological clock had gone in to overdrive.

For fuck's sake, he'd gotten hard that morning just because Sirius had scooped Crookshanks up and cradled the — objectively — ugly cat like a sweet baby, singing him a little song about breakfast and he went to set out kibble and wet food.

The more domestic Sirius acted, the needier Remus got. Thankfully they had started this particular round in their own bed. They had far too many near misses with prefect rounds over the weekend, only the authority of their status as professors keeping the prefects from realising that he and Sirius hadn't actually been laying in wait to catch students in a forbidden location. It was hilarious how a youth spent lying to teachers about being out of bounds lent itself so well to deceiving their students now.

Remus was jostled from his wandering thoughts by Sirius grabbing a fistful of his hair and using it to pull his head to the side. Remus' cock twitched and his gut clenched in excitement just before Sirius bit down harshly on his shoulder. His vision went white, and he came so hard he blacked out.

Remus woke to the sound of an alarm, feeling sore and thoroughly ravaged, sticky in the best and worst places.

"Wakey, wakey," Sirius called softly, gently running a hand up Remus' back and brushing his fingers against the bite on his shoulder. "I let you sleep extra because you don't have a class first period, but you should get up and shower while I'm teaching."

"Mmf. Five minutes," Remus muttered around a mouthful of pillow.

"Just for that, you're going to wear something for me today."

"Like what?" Remus asked, curious despite himself. Sirius normally wasn't much of lingerie, mostly because he knew Remus didn't like how exposed he felt when wearing it, and it didn't do much for Remus to see Sirius in it.

"Hold still and find out."

Sirius placed one large hand flat against Remus' lower back, and Remus soon felt something cool and firm slide between his cheeks. A gasp escaped him, and he arched in to the touch, unable to help the small moan when the plug slipped in snugly.

"Can't have you leaking everywhere, now can we?" Sirius said, pressing a kiss to Remus' head before resetting the alarm and heading out to teach his first class of the day.
