“Nice ass.” Jake laughed, reaching forward and grabbing a handful of his friend’s bubble booty.

“Fuck off.” Tom spat, slapping away his friend’s hand. “I know this is your girlfriend’s body, but I’m not letting you grab my ass.”

“Sorry.” Jake shrugged, still smiling. “I guess old habits die hard.”

Tom rolled his eyes, brushing his long brunette hair from his face. “Whatever, dude. Let’s just get back to the movie, okay?”

As Tom watched the movie, Jake pretended to play along while he toyed around with the body changer app. It had suddenly appeared on his phone one day and, while trying to work out what it did, he had accidentally swapped the bodies of his girlfriend and his best friend who had both been staying over. Not wanting to admit it was his fault, he pretended he had no idea while he worked on trying to solve it.

As he poked around through the app, his cock hardening in his pants as his eyes kept darting towards his girlfriend’s fat butt, he discovered a new slider called ‘Anal’. Pointing it towards Tom, he slowly slid it upwards.

As Tom tried to take his mind off his situation by watching cool action explosions, he suddenly felt a strange feeling in his ass. He reached back and scratched his butt, his backside twitching, but the feeling wasn’t going away. Jake, who was watching with glee, continued to increase the level on the slider.

“Fuck, my ass feels so weird.” said Tom, reaching back with both hands and grabbing his booty, leaning forward and exposing his backside to Jake which only made his friend even more eager. He quickly moved the slider to the max setting, watching as Tom squealed and spread his ass cheeks wide in shock. “Oh fuck, my asshole feels so desperate... God, I wish I didn’t have to say this, but fuck my ass! Please! Shove your fat cock in my butt!” He ripped a hole in the back of his dress, exposing his hole. Jake grinned, forgetting his phone as he grabbed his girlfriend’s hips and forced his cock inside of Tom’s ass, smiling as his friend screamed in pleasure and pain.

“FUCK! FUCK! FUUUuuuuu...!” Tom cried with every thrust, unsure what had overcome him but unable to think of anything but the impulsive need to get his ass fucked and the embarrassment of giving himself up to being violated by a man. “Fuck my ASS! YEAH! Just like THAT!” His eyes rolled into the back of his head as he let the waves of sensation flow through his entire body as he was taken doggystyle for the first time. Minutes passed before he felt his body pushed to the limit with one final thrust, his asshole filled with hot, sticky cum. Collapsing onto the bed he caught his breath, bathing in the shame of his current situation; a young woman so desperate for anal in a torn dress, with cum leaking out of her booty.

Feeling something uncomfortable under him, Tom reached under his ass and pulled Jake’s now-broken phone. “What did you do, your asshole! What happened to me?” Jake said.

Tom held the phone in his hand, which was now almost in two pieces, and shook his head dismissively as it failed to turn on. “You were the one that was begging for anal, dude. Besides, you’re the asshole here, haha.”

Feeling a familiar heat in his ass rise up again, Tom’s eyes widened in fear and disgust. “Oh god, my ass still feels so hungry. I... I need cock. Oh fuck, I’m a cock-crazed slut! What the fuck is happening to me?” he grabbed the nearby remote and began shoving it between his cheeks, the movie now forwarding and rewinding as he tried to satiate his now life-consuming need for cock in his ass. Meanwhile Tom realised what he had done - in his own need for sex, he had made his best friend and girlfriend nothing but a cock-hungry slut who would do anything for a stranger’s cock. Watching his friend violate her dignity to fill her needs, he realised that it was too late. Jake was trapped by his new desires forever.
