The thump broke whatever spell making out in a classroom had cast over her and she stiffened some, pulling away from him just enough to peer nervously over his shoulder and towards the door, jumping as it swung open, two students rushing in holding hands just as she slid off the desk, landing on her feet but bumping against Sirius as she did. "Right I ought to," clearing her throat as the two new arrivals looked far less mortified and far more disappointed that this classroom wasn't free, Lily didn't dare look at Sirius as she scurried past everyone and out of the classroom.
