"You know, this isn't really what I had in mind when you asked me to help your big sister out with her test..." Mickey said, looking down awkwardly at Melody's plump breasts and then back at his enormously thicc ass. He could feel it sticking out behind him, wobbling and clapping together with every movement he made. He'd seen it before, and he knew exactly why so many guys were obsessed with her defining feature as the two incredibly plump cheeks jiggled hypnotically under his gaze. He desperately wanted to squeeze it, just to know what it would feel like to grope a handful of the his hot Asian friend's curvaceous booty, but his friend (and Melody's little brother) John was just outside of the room and besides, the Zoom meeting was about to begin. He needed to focus on the test.

Still, as the video began, he decided that he could get away with something a little cheeky: with a devilish smile he slid his thong down his legs and tossed it across the room, going full commando. It's not like they're going to see my lower body anyway... he thought to himself as questions began to appear on the screen. Thankfully, even in Melody's body it was easy to solve the math equations for an engineering geek like him, and he quickly got into the swing of things until he was already forgetting that he was now a sexy young woman. He was so focused that he didn't even notice that at some point John had sneaked behind him with a devious prank in mind: noticing that Mickey had taken off his underwear, his pussy totally defenceless, he wanted to punish his friend for being such a horndog. Grabbing a thick, pink dildo from underneath Melody's bed he spread his sister's cheeks in one fast sweep, giving Mickey barely enough time to react before he shoved it deep into her pussy and turned on the vibrating function. With a flat-handed spank he dashed out the room again, giggling maniacally.

Mickey bit his lip to stop himself from screaming in pleasure, but it was impossible to think straight with the incredibly hot sensations coursing through his entire body, booty shaking with the intensity of getting fucked as a woman. Worse, he knew the whole chatroom had heard his lewd moaning. "I-I just s-saw a m-mouse..." he stuttered, but as his eyes lulled and his voice quivered, it was obvious that nobody believed him, especially as the moans continued to escape from his lips. He so badly wanted to stand up and chase after John to beat him up, but he knew that if he stood up everybody would see he was butt naked, exposing Melody's filled vagina and fat ass.

With just one last question to go after several agonizing minutes of tortured focus, Mickey just couldn't take the sustained stimulation anymore, so with one final burst of energy he finished the final question and closed the window, nails digging into the bedsheets as he finally relented to the endless waves of sexual tension buried inside of him. Squealing like a slutty bitch in heat he squeezed his ass and enjoyed the sensation once and for all, orgasming with his entire body as a white-hot light overtook everything he had... to then discover, in an exhausted post-orgasmic state, that his screen was blowing up with messages telling him he had only minimized the window: the entire class had observed his exploits in self-pleasure! One even mentioned that all classes were recorded!

In tears of embarrassment, Mickey buried his face in a pillow and cried, just wanting to wake up from this nightmare as he tried to pull the still-vibrating dildo from his pussy in front of an audience of dozens. Seeing his phone ring with a call from Melody, he stood up to grab his phone to try and explain himself but accidentally fell forward with his unfamiliar body weight, forcing the dildo back deep into his vagina as the intense sensations of ecstasy knocked him out cold. When he awoke he rolled over in bed to hear a stream of texts coming into his phone as Melody angrily messaged him, desperately furious with what he had done to her reputation. "[If you're going to expose my ass to everybody like that, you can keep it! Enjoy your new life as the college's most notorious slut!]" it read. Mickey gulped, realizing that he was now stuck for good, and that Melody's fat Asian ass was going to be his forever.
