Coming Out With A Plus

"Now go on and suck that dick!" Martin commands Mey with a shabby laugh.
"I don't know... it's pretty big." her voice is but a whisper.
"Oh so you pulling that excuse again..." he returns, which gives me a strange that these two have some history. "You are a cock-sucker bitch, and when you see a cock you suck it, understood?!" he blurts at her. She changes in front of my eyes again, not much, but her lips become slightly more pronounced. "And you suck any cock, any size, because that's what you love to do Cocksucker, right?" The way he said that word, like it was her name, gets me scared again. Can he really do that? Just change her name to... Cocksucker? But before I can delve on that thought further, her weak "Yes" is followed by her going down on my dick. I feel her big, wet lips wrap around my shaft, and from the first second I can tell that this isn't her first time working a shaft like this.

"You like her?" he asks me with a brotherly tone, and a first straw of hope makes me think I can get out of this mostly unscarred.
"Yeah, it's nice." I say with a fake grin. I feel pity for Mey, but this is a me or her situation it seems.
"Great. Don't cum before I say so, though!" he orders me, and an odd tingle downstairs tells me that cuming is outside of my options now. Then he turns back to Mey, who is going on my dick with a clear hesitation. "You love sucking dick like nothing else in this world." Martin instructs her "No matter the size, or shape, or whatever. You go crazy over any whenever you have the chance." Mey's movement clearly becomes faster at this point, and despite the dangerous situation I can feel myself getting closer. I look at her dangling mountains of tit-flesh that now somehow turns me on dramatically, and keeps my dick rock-hard. I have to give in to his manipulation at this point, no matter how much I used to be an ass guy, but it's for my survival.

"In fact you wouldn't even want a dick anywhere, but inside your mouth, isn't that right, Cocksucker?" Martin instructs her, and her moans suddenly become audible. She is clearly enjoying this now, and goes wild on my cock. I can't help but to groan also, she's handling my prick like a complete pro, which she probably now is. Martin watches his private show for a while, and I would certainly have gone over the edge by now, if it wasn't for that block he installed earlier. I just pray that's a one-time thing.
"And you certainly wouldn't put one down if it was 'too big' anymore, right?" he teases her. I think Mey shakes her head, but it's hard to tell with her movement.
"And you won't stop either until you made the guy cum ever again, right?" In my head I am painting a picture of her getting a blow-job from her, and she blue-balled him on it. I have no idea if that's what happened, but it would explain a lot. Thinking however becomes difficult, as I now constantly ride the very edge of that orgasm, and I am unable to cum. Groans escape me, I start to sweat, and my knees start to buckle. But luckily Martin is focused on unleashing his anger on her.

"Not even if he has a horse cock, right?" his voice suddenly becomes darker again. I feel a tingle and under heaving moaning I watch my dick expand rapidly, till I end up at 10 inches or so. Mey visible has troubles now, but is clearly very motivated to continue.
"Not even if his dick is almost too big for your mouth, right?" his fury is now clearly visible in his eyes. I feel my cock expanding further again, in all directions this time. And her mouth is tightening around my shaft, or rather: my dick becomes too big for her mouth. It's now wide as my wrist, and probably 14 inches or so.
"And you certainly swallow every drip, you Cocksucker bitch, right?" Mey whimpers in pain from having her jaw stretched so much, while I desperately try to not make any unexpected noise to not draw any attention, even though her blow-job has almost become **** at my new size.
"Even if he cums a gallon down your throat." he finishes, and I feel a tingle and growth in my balls. "You. Cum now. Empty your balls into that bitch completely!" he orders me, and instantly that barrier is gone.

My head explodes as a sudden orgasm overcomes me and I have to grab the teacher's desk to not fall to the floor from the insane pleasure. My entire lower body becomes a cramp for a moment, then my balls release an insane amount of cum right into Mey. She swallows like her life depends on it, even if she can barely wrap her lips around my shaft. I see my cum bloat her cheeks, getting squished out through her lips, and eventually it even starts to drip from her nose, but she keeps swallowing. Her face turns bright red as she lounges for air, but my balls keep going. My loud moans must be audible through the entire school at this point, but there is nothing I can do to stop it. And when it eventually dies down naturally on it's own. I can't help but to sink onto the teacher's desk panting.

Mey is finally able to let go and drops to the floor almost instantly, gasping for air. Her breathing is loud and clearly she was this short from suffocating, but eventually seems to recover. I feel bad for her, but if I say anything at this point Martin would just punish me like he punished her.
"Well done, stud." Martin laughs and pats me on my shoulder. He looks down at my now gigantic dick and a grin forms on his face. "You can keep the dick." he decides. While that size is crazy, he could have as well just shrink it to a tiny pickle, or give me a pussy, probably, so as ridiculous as my size now is, that's probably the better end of this bargain.
"In fact I want everyone to know what a nice big cock you have." he suddenly continues and I feel my back hair raising "So everyone knows what size of cock this Cocksucker sucks on." I feel an alarming tingle in my cock again, but nothing apparently changed.

"Go back to your chair, I got more business with this chick." he orders me. I nod exhausted and pick up my clothes. Once back at my desk I start to put them back on, while luckily most eyes are glued to poor Mey at the front still. Yet when my erection slowly fades, and I honestly have no idea where to considering the now humongous size he had blessed me with, I finally realize the last part of his curse. My dick only becomes soft, not smaller. It stays at 14 inches, it stays wide as my wrist, it just becomes soft. My balls also have grown almost to the size of coconuts and hang down heavy from my groin, yet look strangely in proportion to my new dick. Like someone enlarged my old equipment and photoshopped it back onto my body, just way more real. I do my best to stuff my new assets back into into my pants. My dick now causes a bulge down to my knee, and the bulge of my balls also left little to the imagination. Surprisingly my pants fit my new size, even though he never said anything about that. It seems reality just adjusts with what he is doing, which would explain a lot. And when I finally look down at my pants and the massive bulge I now sport it is as he had said it: everyone can now clearly see what size Cocks... Mey had taken.
