You’d been careful.

At least, you thought you had.

Spending the night in Bill WeasIey’s dorm wasn’t exactly a new thing. Bill had a way of making it seem easy — a quiet smirk, a tilt of his head, and you’d find yourself tiptoeing through the dark just to end up tangled in his sheets, his voice a low murmur against your neck.

Last night was no different.

When you woke, sunlight was streaming through the cracks, catching on the gold in his hair. Bill was still half-asleep beside you, the corner of his mouth lifting when you shifted.

“Leaving already?” he murmured, his voice rough with sleep.

“If I don’t, I’ll be late for class.”

“Shame,” he said, eyes still closed. “Was enjoying the view.”

You’d rolled your eyes, pressing a kiss to his cheek before slipping out of bed. Your clothes were scattered everywhere — your blouse on his chair, your skirt on the floor, your tie somehow hanging from the headboard. You pulled everything together as quietly as you could before sneaking out.

It wasn’t until later that day, sitting in the courtyard with your friends, that your phone buzzed.

You smiled when you saw his name, expecting something sweet — until you read the message.

You might want to check around my bed next time before you leave.

Your brows drew together, confused. But before you could even type back, another notification popped up. A photo this time.

Your breath caught.

Your panties — black, delicate — folded neatly on the edge of his bed.

You blinked at the screen, your stomach dropping as you typed quickly.

Oh no…

Another message arrived seconds later.

Oh yes. Careless of you, love.

You exhaled, half in disbelief, half in embarrassment.

Another message lit up your screen.

I could return them… but where’s the fun in that?

Your fingers flew.

Bill…

You could picture him smirking as he leaned back on his bed, phone in hand, watching your name pop up again.

I think you should come and earn them back.

You blinked at the screen, pulse kicking up.

Earn them back?

Your phone buzzed again.

That’s right. And if you take too long, I might just keep them as a reminder of you wandering around here without them.

You stared at the message, your heart doing that dangerous little stutter it always did when he pushed just far enough to make your breath catch.

And up in the Gryffindor tower, you just knew Bill WeasIey was grinning like he’d won.
