Lucky day?

I try to find a comfortable position on my chair, but having to deal with these enormous assets makes it very difficult. Feeling my cock on my thighs all the way down to my knee is irritating but bearable, but those huge balls I have to deal with now make every movement difficult. My pants somehow adjusted, which was a relief to say at least, as that almost head-sized bulge from my upgrades balls would have not fit into any pants I owned previous to this change. Also these pants seem to be kinda stretch, yet still every movement causes a bit of a strain in the fabric and with that a squeeze of my jewels. When I look back up however I see how Martin has bent Mey over the desk and inserts his at least 10 inches into her pussy from behind. She's protesting, but mostly because she wants to him to let her suck his cock. Her gigantic tits look so out of place on her small frame, like a surgeon has gone wild. The jiggle of that tit-flesh is oddly mesmerizing, and as I recover from my recent orgasm also sends tingles down into my sizable dick. Inevitably I feel myself slowly hardening, till my cock is straining my pants. Just as he said: looking at big tits now gets my dick hard it seems.

My predicament could have been worse, in fact there even might be boy out there wishing for exactly this to happen, but what Mey has to go through now definitely is something else. With those knockers she'll probably have back issues before she hits 25, and together with her urge to suck off guys she probably end up in porn before that. If she is lucky, and I don't even want to think about the alternatives. I distract myself by wondering why only I seem to be able to realize what's going on? The rest of the class is just sitting there, staring at the two fucking, some even take notes like this was a completely normal class. Suddenly I feel a hand on my shaft. It's Jen, a rather popular blonde with some nice C-cups. Previously I also enjoyed her ass very much, but now my eyes just seem to jump to every girl's rack instead.
"What are you doing?" I hiss to her. Her hand slowly rubbing over my dick broke the last floodgates I had been desperately trying to keep shut, and my dick now fully hardens in my pats, at least as much as the fabric allows.

"It's so huge..." she says staring mesmerized at my cock "... why haven't we been doing things before?"
"Now is not the time!" I try to get her to stop. I don't want to draw any more attention from Martin. He's busy currently hammering Mey's pussy, but sooner or later he will be done with that, and then god knows who else he uses his powers on.
"We could excuse ourselves to the bathroom, class is boring anyways." she oozes sex into my general direction. The obnoxious moans and grunts from the front would suggest otherwise, but apparently this is a normal class now. But it strikes me that maybe this isn't such a bad idea after all. Not that I suddenly want to fuck the next girl, but sneaking out of class while Martin is... distracted... maybe that's the best thing I can do at the moment. He is kinda fixated on Mey, his hands kneading her assets, and his groans suggest he's not really focusing on anything else.
"Ok." I whisper "But let's make sure no one notices." I get up and carefully start to sneak out of the class, trying to stay out of Martin's vision.
