From Fan to OnlyFans (TG, TF)

You had finally gotten home from work and were about to let loose. You opened OnlyFans on your phone looked through all your favorite girls. You went through them all, and still were yearning for more, so you paid for another girls account, but you forgot you last used yours girlfriends card and it got charged to her. She saw a notification on her phone and was fuming and stormed into your room. "Am I not good enough for you?" she screamed at you. "No no, I just like supporting female creators, I just think their content is entertaining and not in a sexual way!" you clearly lied. "Alright, well how about you help support me!" she screamed throwing a bottle of pink liquid at you. Things very quickly started to become weird.
    First your hair grew out long and brunette, it was the softest hair you had ever felt. Then your eyes became much prettier and your nose slimmed and your lashes grew. Your lips puffed into two sweet pillows were incredibly soft. Next your adams apple disappeared right as you screamed and your voice cracked and your scream sounded straight out of a horror movie. Next your chest started puffing up and expanding into two breast. They kept growing, and growing, and growing until you had two jiggly double D's. You started bouncing them up and down in amazement when your girlfriend grabbed a squeeze. "Mmm those a plump." she said with a wink. Next your waist caved in and your stomach became more defined as your arms shrank. Your thighs puffed out into two pillows and were super jiggly. "How did you do this?" you said in a sultry bimbo voice. "With a potion I made, bet you didn't know I could make magic potions did ya?" she said laughing. "I can also apply curses!" she cackled as lights shot out of her hands. Your butt grew, but only slightly. "What did you do, make my butt the tiniest bit rounder?" you said thinking her curse had failed. Just then she snapped a photo of you. "Nope, I'm about to announce your first only fans live stream... and for every dollar donated, your butts gonna grow." she laughed evilly. 
    Before you could argue she had started the stream and your butt was starting to grow. With each donation coming in it got bigger and bigger. "Start shaking it!" your girlfriend screamed, and even though you didn't want to your body forced you to start shaking it back and forth. It kept growing and growing and eventually you started twerking. As you were twerking donations started flooding in faster till you had reached the world record for largest butt and your jeans ripped right off to reveal panties you didn't even remember putting on. You whipped of your shirt because it felt like it needed room and you were wearing a bra too. More donations came in and your butt had become the size of two car wheels. Your panties soon ripped off as well and your girlfriend started massaging your butt making you moan. This only increased the speed of donations. Your butt had become as big as a whole plus sized model and kept growing, but just as things seemed to be peaking, you saw something you couldn't believe on the screen. An $1000 dollar donation. Your girlfriends mouth was a gap realizing that this would also screw her. Your ass was expanding faster than you could imagine and as your girlfriend tried to run away she got smashed into the wall between one of your cheeks and it. Your butt kept growing and growing until eventually the room couldn't contain it and the walls started cracking, then the whole house was until their was nothing left of your home. You girlfriend waking up from being knocked out by your massive ass ran over to her phone and ended the stream. "Alright... well, I messed up to... so now we're even." she said with an awkward smile. "Sadly I think you concussed me so no magic for two weeks... but your ass does look really soft." she said climbing up and and laying down. You could feel her soft hair run a crossed it ever time she tossed or turned in her sleep and as she squeezed your fat like it was her childhood teddy bear. You were left their not being able to move, leaning back into your own ass, realizing it was quite comfy, and falling asleep scared for how long these next two weeks might be...
