It's cold.
It's freezing cold, cold to the bones, swimming in Arctic waters cold.
Which is, you know, exactly what he's doing, so that figures.
He's not, not even a little bit. He's gripping the edge of his seat like his life depends on it, breathing heavily, and looking around at the fact that they're in plain view of six other people. It's making him precome a lot, and honestly he's having to do his utmost to hold himself back from coming—which is itself kind of fun, he had not expected that not coming could feel this nice.
So Ruby can start trying to make him squirm. Pull his foreskin back, run a thumb around his tip to spread his precum around, just generally play with him.
He does not actually have it in him to hold back all that much longer and he throws Ruby a panicked look when he's about to—
But Ruby was expecting it and when Onmund is close enough he leans down to put his mouth around Onmund's cock.
It's just in time; as soon as Ruby is there he's coming, gripping his seat even harder and biting down on his lip to keep himself from making disruptive noises.
This is in fact much nicer when he's doing it with someone he wants to do it with, actually. He swallows, because he doesn't want Onmund to get sticky in the middle of class because of him, and also because it's really hot.
Onmund... succeeds... at not disrupting the class.
He also has the post-coital clarity that he just got jerked off to orgasm and then had his cum swallowed by a dude in front of his teacher, a teaching assistant, two other students, and two other people who... admittedly are also fucking.
...were. Were also fucking. It seems like they stopped at some point, or are finished, or something. They're still there, but how they're just cuddling and half-watching the lecture.
Well, the orc catches his eye and offers him a thumbs up which makes his head immediately snap back to look at the teacher so quickly he's sure he must have made a cracking noise. He is also most certainly not looking at Ruby, no sir, he is paying attention to the lesson, yep, nothing to see here.
Nine help him.
Ruby now has a grin like the cat who got the canary and even though he is not himself avoiding looking at Onmund his world is a lot less shaken by the idea of exhibitionism being unremarkable. He's definitely getting used to this really quickly.
Which also means he can get back to paying attention to the lecture a lot more easily and quickly than Onmund can.
Unfortunately for Onmund's ability to pay attention, lectures on herbology are very boring. It stands to reason that this kind of memorisation is necessary for proper mastery of Alchemy, but that doesn't make it any more interesting. He thinks he's probably not going to be attending any more lectures about this particular subject.
The human and the orc leave the lecture hall halfway into the lecture, and the last fifth of it is dedicated to some very very basic techniques for figuring out herb properties on the fly which will be expanded upon later.
"Dinner?" suggests Brelyna after they're dismissed.
"J'zargo could take a half hour to socialise with the other Apprentices," Ruby counters.
"No, but it's helpful for that. People are much more willing to spend time with you helping out with magic if they also like you as a person."
"Most other people are. I am. And besides..." He makes a flame, then does the same demonstration of colours he showed Onmund yesterday. Then he draws just the colour out of the flame, making the flame itself become a mostly-transparent patch of heated air floating above one hand while hue-shifting light dances above his other palm.
"Apparently whoever I was before the amnesia I already knew some amount of magic. And I could teach J'zargo..."
