MJ knows about it.
Of course. She knows everything, and Peter still hasn't dismissed the idea that she's psychic or something.
She doesn't really comment, just calls him a dweeb and goes back to her book, which, really, just about sums up his relationship with MJ.
Then they sort of do that thing where they get closer and she starts just casually sitting across from him and Ned one day and they sort of gape at her but she just raises an eyebrow and they roll with it, then it keeps happening, and, well...
It just snowballs from there.
She stops calling them idiots, and if Ned doesn't get something, she rolls her eyes and tells him the page number and book where he can find it, and when when they say thanks she sort of snorts and calls them stupid and, well, it's not quite the typical kind of affection, but this is MJ so Peter figures this is something that would be super affectionate coming from anyone else.
So Peter starts buying her random tea and Ned discusses fan theories with her and she gets those times where she gets so caught up in a discussion with them that she forgets to call them stuff like "dork" and "idiot" and just lights up but acts chill afterwards.
Then one day she just comes into class, pulls off her jacket, and tosses it at Peter. "Enjoy." She says, raising an eyebrow, and Peter doesn't even need to ask why, just kind of feels his face burning and pulls it on with everyone watching.
Rumors of them dating escalate, but obviously he keeps wearing Ned's clothes, too, so people are speculating that it's a threesome.
(It's so, so awkward.)
When they finally get a chance to talk without everyone watching (in the cafeteria, where everyone watches, but Peter can pretend they're not, as opposed to the classroom, where everyone's pretty obvious), Peter raises an eyebrow at MJ and notes, "It's missing a sleeve."
(It is. It's a nice, neat, black and white striped dress jacket that has one sleeve extending to the elbow and the other just not there.)
"I bought it like that."
MJ says it so deadpan that Peter is honestly wondering whether or not she's lying or telling the truth.
"It's okay if I'm your, like, charity donation box." He says, feeling a bit awkward.
She makes a face at him, baffled and irritated and bored all at the same time. "Dude, no. I'm expecting that back, and washed, by the end of the week."
(Come to think of it, MJ has a weird fashion sense, so maybe she ripped it off to make a stand or something like that. He wouldn't put it past her.)
Peter stares, and is suddenly aware of the smell of MJ on the shirt, the way that the faded books and wood of a bookshelf and the dust of a corner clings to it, embedded like the shirt's made of it, then there's also spaghetti and microwave lasagna and instant noodles and cafeteria smell on it and he realizes that she must have been wearing it for at least two days.
"Oh," He realizes, kind of stupefied. "I'm not your donation box, I'm your washing machine."
MJ sort of shrugs and grins at him, wide and mischievous and bright. "You'll wash it for free, so why not?"
"I'm not a free washing machine." He's not sulking, he's not.
(Okay, fine, maybe he is.)
"Right." MJ took a sip of her water. "And I'm not a feminist. We both know that you'll wash it, and we both know that you have some sort of weird thing going on where you don't wear your own clothes, so why not?"
"MJ!" Ned groans, horrified. "We're trying to break him out of it!"
"Why?" MJ shrugged. "Sure, it's a sign that he's mentally unstable, but we already knew that, and if he likes it, why not?"
Ned buries his face in his hands and groans, and Peter does a kind of weird thing where he makes a weird giggly but nervous sound.
(He wears it to school, the next day, and washes it at night, bringing it back nice and crisp and neat, all folded up in a little bag.)
(MJ strips off her pale pink jacket that looks suspiciously like a pajama top and tosses it at Peter in retaliation.)
A/N: I swear, I'm this close to being done and I'm not emotionally prepared for that.
