Its... Amy

My eyes widen as I see the car door open revealing Ashley's big sister Amy, instantly seeing that she's gone through some demon assisted growth as well. She looks even bigger than Ashley! Amy's a towering 8ft tall, her beast of a bulge though seems to be every bit as monstrous as Ashley's. I'm pulled into the car before I can stop or say anything to them, the whole drive back has Ashley feeling up my massive ass, every once in awhile even Amy sneaks in a grope or three. By the time we finally pull up my body has been so teased and toyed with that I can barely focus on trying to get out of the car. It's only a few moments my shaking legs are touching the ground, before Ashley has moved to open the door and Amy has scooped me up like a beloved puppy.

I'm buried face first into Amy's enormous cleavage, meanwhile my ass is bounced and groped non stop. I can feel Amy's bulge throbbing and slowly building up as I'm carried into my home. Both Ashley and Amy carrying me up to my room, bulges straining as they practically start stripping right in the doorway! I'm kissed deeply, the sisters taking turns seeing just how deep they can get the kisses as they tease themselves further, working themselves into an absolute frenzy of lust. Their tops are tossed aside, shoes and socks thrown about, I find myself stripped nude with my massive wobbling booty jiggling in front of them. "Mmm putting on a nice little show for them darling~ But what's this? Oh! looks like I just..." The demon's voice trails off and I sigh in relief, thinking she was pulled away by something else.

Barely 10 seconds later I find myself hovering in the air, my belly bulging out MASSIVELY as my ass is suddenly spread incredibly wide! I don't have a moment to catch my breath, powerful thrusting HAMMERING that monstrous steel hard rod into me, my belly bulging out enormously as my eyes cross and my legs shake. My body hitting release before I have the time to realize what's happening, back arching as I feel my hair getting pulled on from behind. "Mmmm FUCK you are TIGHT~! Like the new DEAL I made~?" I hear the demon in my ears, my tongue hanging out my mouth as she seems to just pound FASTER into me, a new little burst of cum milked out of me every few thrusts. Without warning I find myself lifted up HIGH, **** to look up as my belly bulges out with the demons dick. Another powerful thrust, another girly moan, moments before I'm pulled into a tight hold, held in place and nearly buried back into her tits.

"Mmm look down boy~" I just barely managed to do that, seeing her enormous cum tanks swinging and hanging there, I can swear I can SEE them throb ready to start unloading. "Not yet cutie, I hope you didn't think you were taking COCK too often today, tomorrow is gonna be even MORE intense~ I mean... look what these new deals gave me~" I hear her practically purring in my ear, then I see it happening, her new growth. At first I thought her dick would grow but, it isn't. Her balls on the other hand are gurgling and swelling RAPIDLY, like a pair of balloons being filled up. They had already reached 3 times the size of basket balls with the last growth, now I couldn't hold back the feeling of fear as I watched them swell and fill. SO. MUCH. BIGGER. By the time her new growth had finished, her nuts were each resting on the floor, her balls each the size of a giant BEAN BAG CHAIR! "Mmm fuuuck, finally I get to start channeling all that pent up lust, all those loads I've held back, all to prepare... To FILL. YOU. UP!" The final words are followed with her massively oversized cock HAMMERING into my ass and making me bounce in her lap. She may have been using only the strength in her hips to send me back up her shaft, but when she pulled me back into her thrusts it was with one hand on my hips while the other pulled on wait, WHY WAS MY HAIR LONGER NOW?! M-my face was looking more feminine too! What the fuck?!

I couldn't focus much more on the changes though as suddenly she stood up and began to hammer me down onto her thrusts, almost growling as she used me like an onahole in front of my childhood friend and her sister! They were less than a foot away, I couldn't see their faces around my bulging belly. Thankfully they couldn't see any of this right? "Mmmmm so this is what happens when she makes a new deal? I'm tempted to make another right now~" My eyes widened, t-that was AMY! T-there was no way they were seeing this right? "Fuuuuuck isn't it great? He looks amazing too! The changes she's putting him through, it's no wonder she made us so HUGE~" T-that was Ashley! N-no, they could see this? A moment later the demon nibbled at my ear, her titanic hard on throbbing inside me powerfully as she held me in place. A few moments later I heard her giggling in my head again, my vision seeing past my stretched out belly, to see both Ashley and Amy stroking their cocks almost desperately! "Feel that boy? That THROBBING inside you~? There's so MUCH just BEGGING to flood you like a breeding bitch~ Mmm I'm looking forward to this weekend, I'll give you EVERYTHING darling~ But not yet, tomorrow is only Thursday after all~"

I felt her pulling out, foot after foot of her behemoth sized cock out of me. It was only then that I realized she was holding me up, my gaping ass tingling and twitching as she held my legs up, putting my entrance on display for Ash and Amy. "No need to hold yourselves back! He's all nice and prepared for you so help yourself~" I heard the demon call out, the two sisters practically pouncing on me as I finally god a good look at their monstrous cocks, both of them 5 and a half feet long, while their girth was nothing compared to the demon's it was still almost obscene just how FAT their cocks were. I didn't have the chance to refuse them, to stop them or anything. The demon dropped down and held me in place, my lips at the perfect height for the sisters to enjoy my throat.

Minutes later and my throat is stretched out massively, a choker had been put on me only to instantly SNAP it into pieces, Ashley's cock seeming to have gotten a LOT harder just from the chance to break the choker. Now she was pounding my throat almost furiously "GLUK GLUK GLUK GLUK" Were the only noises coming from my throat, Amy in the background licking her lips and pumping her shaft as she watched her sister put my throat through a stress test. I could just barely manage to see hearts in Ashley's eyes, they slowly flickered out though, especially when the demon spoke again. "Mmm isn't his throat WONDERFUL~? And to think he was letting a teacher TAKE HIM in the hall right in front of you~!" The demon giggled out evilly, Ashley's movements stopping as she remembered that, a look of anger on her face as she suddenly pulled out of my throat, Amy staring down at me with a look of fury. I tried to speak, tried to tell them I had no say in it, that it happened so suddenly without even a hello.

Instead the demon snapped her fingers and I had to watch their cocks swell even thicker, their muscles BULGING with strength as their balls SURGED with MASSIVE growth. Amy grabbed my head, palming it like a volleyball, I only realized the demon had let go of me and vanished right as Ashley grasped my hips from behind. "I didn't-" That was as far as I got before Amy made my soft, plush lips stretch around her massive tip, meanwhile behind me Ashley was pressing against my ass HARD. I tried to brace myself, I tried to hold onto whatever I could... Amy wasted no time though, HAMMERING into my throat as she used my lips and throat like a favored onahole, Ashley meanwhile stretched my ass wider and wider as she slowly **** her way inside. Amy's hands grabbed at my head before pulling my hair into a set of handlebars as she pounded my throat angrily. Meanwhile Ashley was holding onto my ass and hips with her hands, driving herself forward as my belly bulged out from both their shafts. "PLAP PLAP PLAP PLAP" The sounds coming from my ass were loud, I swear they were getting louder even as the demon giggled in my head. "Mmm punishing you for slutting yourself out at school, Poor Ashley must feel so angry with you! I know, why don't I... Give them some ideas~?" With that her presence vanished again and I spent the next 20 minutes straight getting slammed into at both ends.

It's about that time, my mind delirious, legs shaking, my dick letting out little bursts of release again and again that they finally fired their first loads into my body. My eyes went wide as I felt a LOT more than they looked to have saved up just PUMPING into me, my body quivering as they both pulled out. I gasped for breath, tried to form words and apologize, then I realized Ashley hadn't pulled out... Amy walking forward as she helped her sister lift me up higher, my new liquid weight making it harder. My legs lifted up high as Amy's cock lined up and began to push in alongside Ashley's, I tried to speak, tried to explain, Ashley was barely a quarter of the way in when Amy managed to stretch me wide enough to slide in further. I was a moaning mess, body quivering, legs shaking, both Ash and Amy slowly pushing in much MUCH deeper! It took them almost no time to get past the halfway point, when they did? They planted their legs in wide stances and began to RAIL my once tight hole, switching back and forth between who thrust in and who pulled out. I came against Amy's powerful abs only for them both to press in tight, trapping me between them, both of them pulling back. A kiss to my cheek from Amy, one on my neck from Ashley was all the warning I got before they both SLAMMED into me! I quickly lost track of time with them both ruthlessly pounding into me, my tongue hanging from my mouth as they both took turns kissing at me. Their grips tightening on me when they finally got close a half hour later, only for them to thrust even faster, trying to milk and DRAIN their balls into me. When they finally released their second loads into me, it was with their balls rubbing and throbbing against each other, cocks throbbing against each other inside me, their loads pumping out more and more than the previous two releases combined.

That was about the moment where I fainted in their arms, right as the moaned and started thrusting their still iron hard cocks into me body once again. At least I should get some good rest right? R-right?
