Problems Blown Away

"Oh no, someone hit you with that new party app?" I suddenly got thrown out of my world of thoughts, when I heard Sam's sultry voice from my side. There she was: hair dyed blonde, C-cup boobs tactically presented in her skin-tight top, and a wicked smile that made me want to undress on the spot.
"Yeah, seems like that happened." I returned knowing exactly why she was here. But that also was a good opportunity to get rid of my problem.
"Poor boy..." she came closer, just that perfect distance where my raging boner was practically hovering in front of her entrance "I hope it is not too straining? I heard it only goes down if someone else gives you a good time." Her voice made it clear how much she was enjoying to tease me like this. Normally I would have ditched her, but right now I was so horny, I was ok with almost anyone to get me off.
"If I just knew someone hot who could help me out on this..." I flirted back, and her brief smile told me she was in. Jaden gave me a painful stare when we left for the bathroom a few minutes later. He had the same problem, but no hot girl came out of nowhere to assist. I knew Sam would come up with demands as well, but probably nothing that couldn't be solved by fucking her brains out. Lucky for us there was no one else in the bathroom, and a moment later we were in a stall with my pants down and all of my raging 9 inches on display.

Sam wasted no time and I could feel her lips and fingers on my very demanding shaft right away. But she carefully kept me far enough from cuming, certainly so she could come up with some demands before. But honestly at this point I was ready to say yes to about everything. She had this breeder fetish, and last time milked my cock till my balls hurt. Not that I am complaining, but then I have other options as well, some that work better with my own kinks.
"You know how this curse came into play?" she eventually stopped. My brain was pretty lost in arousal at this point, but I knew the negotiation part would come.
"No idea." I mumbled, hoping that she would at least go on with her hand.
"It was us at a sleepover yesterday." she continued with a sadistic grin "You know Janet? She just loves hard dicks, and that's what she did."
"Oh yeah, I remember her..." I groaned. That girl kept me on the edge for over an hour, worshiping my cock in the meantime. I was nice, but there was little fucking involved. A part of me felt like I should be worried about girls having that kind of power, but then I realized it is all perfectly fine.
"Do you know what I added?" Sam put on a grin so dirty I just knew I was doomed. "Be my cum fountain."

Suddenly I felt an odd tingle in my balls and I watched them expanding right in front of my eyes, till they were each about the size of tennis balls.
"Wow." I was surprisingly less astonished then I had expected to be, but somehow this all felt perfectly normal. Sam on the other hand went crazy and started kissing my new 'cum fountain' like she was about to cum from it.
"Oh fuck yeah, cum for me..." she suddenly started chanting "Cum for me boy!" She however conveniently started pumping my shaft again, and this time with the clear intention to get me over the edge. Her pleading eventually got muffled when her lips wrapped around my cock, where she expertly made me feel pleasure from out of this world. She was good at this, damn good...
"Oh fuck..." were my last words before she sent my brain into oblivion. I could feel how something massive was prepared down there, but I hadn't been prepared for what volume I was now capable of. The first thick rope probably already contained more juice than my normal orgasms combined, and it just started from there. Massive loads splattered right into her face, and she was more than happy to receive them. While the orgasms did not last much longer than usual, the result was messy. Me panting and completely overwhelmed, and she dripping with my cum like someone threw a bucket of milk into her face we sat there quietly for a few minutes, till my dick finally was fully limp again, yet still in her hand.

"Jeez..." I eventually found my speech again. It was clear that this was now my usual volume thanks to her party spell, but that was perfectly ok. Sam in the meantime proceeded to clean herself. "Well at least my dick is down to a size I can hide in my pants again." I commented. Before my thoughts could return to poor Jaden, who was probably still standing before class with his dick at 100%, Sam suddenly giggled. Not that happy giggle, but that evil, wicked giggle only girls could do.
"Do you know what Liz did?" she eventually started.
"No." I couldn't recall having sex with her, but I knew who she was. Shy girl, brown hair, tomboyish but cute.
"You know she's into huge dicks, and obscene bulged." Sam's grin would have scared the devil at this point, but oddly I felt perfectly ok with everything going on. "So her line is shower not grower."
"Oh come on..." I gasped, when I felt another tingle in my groin. I watched my cock expand again, but this time I at least didn't get one of those relentless boners, yet my cock still soon enough was back at the massive size I am when erect, just not erect.
"This is for you, Lizzy..." Sam giggled and quickly took a pic. I am usually not a fan of this, but somehow this as well felt perfectly ok. Girls deserve to see what a guy has to offer went through my head, and it was probably true.

My pants still fit somehow, but the bulge my now permanently enlarged dick caused left a clear message to anyone looking: this guy is hung. I was ok with it though, even though I knew there was no more hiding of that monster anymore from now on. And those oversized-balls below looked like I pumped them with saline or something. But it was fine, girls are allowed to have some fun as well.
"Just please don't make me hard again." I asked her "Too exhausted after this one."
"I won't." she promised "... if you invite me to dinner. On let's say Friday?" I rolled my eyes, but agreed.
"Fine." Not that I had any options here. That, and certainly sexy afterwards, or I spent the next few ours with a raging boner again.
"That definitely was the best pact we girls ever made." Sam giggled, before she unlocked the stall again. I followed and tried to get used to the much increased jiggling and movement of flesh in my pants now. Also I had to call Cathy for Jaden, I remembered.
