Andrea convinces you it's not necessary

You leave Andrea's place at a brisk pace, but before you get too far, she catches up to you, grabbing at your arm. "Hang on, Isabella~ I don't think you're used to all this yet. If you start running around, you'll get all sweaty and ruin your make-up. Besides..."

She pauses, waiting for you to turn around and face her, which you do reluctantly, still in a hurry as you are. "...If you look like this," she gestures to herself, then to you, "...you can get away with being a little late~."

Her first point is pretty good, and you'll have to just trust her on the second one you suppose. Running to school in your skimpy schoolgirl outfit wasn't all that appealing anyway.

So in the end, you walk to Andrea at a steady but unhurried pace. You'd have just barely made it by rushing you suspect, but instead, you make it to school around 5 minutes late. Unfortunately, another obstacles rears its spectacled head.

"Look who's wandering the hallways during class again." The hall monitor's grating voice greets you as you enter the building ahead of Andrea, his eyes already roving your body hungrily. You sigh...looks like you'll be more than just a few minutes later after all.

Andrea's voice sounds in your ear a moment later though. "Don't worry~ This kind of guy is easy to handle."

Andrea steps out from behind you, making the hall monitor jump in surprise; he apparently hadn't thought you were with anyone. Before he can say anything, she walks up and grabs him between the legs, her voice purring seductively.

"You don't mind letting us by, do you...?" Her hand rubs the quickly stiffening tent in his pants, making him groan as he tries to reply. It's obvious the hall monitor doesn't have much experience with women; outside of Attendants or reluctant favors from people he's pressured with his hall monitor status.

Not giving him a chance to recover, Andrea gives his cock a skillful through-the-pants rubbing, her voice cooing at him as she does so. "No need to speak up, big boy...just let me make this big hard cock of yours feel good~"

It doesn't take long before the hall monitor gasps loudly, his body quivering as he visibly cums in his pants, Andrea's hand not slowing down until his legs go limp, depositing him on the floor at her feet.

From where he's sitting, he can see straight up Andrea's skirt, where he stares, looking dazed. She doesn't seem to care, blowing him a mocking kiss. "That's a good boy. We'll be going to class now...you might want to get cleaned up~"

Giving you a grin, Andrea waves for you to follow her, leaving behind the humiliated, but clearly satisfied, hall monitor...getting him out of the way in barely a minute, and with all the mess contained to his own pants is a stark contrast to how long you spent letting him fuck you yesterday. Maybe it'd be good to learn more from Andrea in the future...
