The Slut-box Challenge (a quickie)

It was the latest craze sweeping the nation.  Sign up for the 'Slut-box challenge' and at any moment you might receive a mysterious email.  Opening it would trigger a magical transformation and give you a limited time frame to try and win the game with a reward and a punishment for failure.

Having signed up for the challenge as a joke weeks ago, Riley was surfing the web whilst sitting on the loo (something his Mom hated) when an email arrived.  He'd forgotten all about the challenge, and hadn't really believed it was a real thing anyway - so opening it, he was rather surprised as his skin began to tingle and he felt a strange transformation overcome him.

SLUTTY GIRLFRIEND CHALLENGE - You are now your best-friend Max's slutty girlfriend Riley.  You have one hour to make him cum all over you or you will be trapped as a girl forever.  If you win - everything will go back to being normal for you.

Riley moaned as he transformed... his hair turning blonde and his sneakers going pink as the magic email altered him into a sexy girl and the clock on the challenge started counting down.

"Holy shit, the challenge is real," he squeaked in fear.  "Ewww, I need to make Max cum over me or I'll be trapped like this forever!"

Pulling up his lacey panties, Riley ran out of the house and jogged down the street to Max's house, his new tits jiggling as he jogged.  He blushed as he saw guys were staring at him - how embarrassing.

Max was totally clueless as Riley entered his house. His memories had been altered so he thought Riley really was his girlfriend and to him, nothing weird was happening.  He was confused as to why she kept checking the clock, or why she was so freaked out about touching his cock - but then he had no idea that Riley was really a guy.

"Listen Max, you gotta cum all over me," muttered Riley as he blushed and pulled his friends dick out  "We gotta hurry up too... let me get your cock hard and then give it to me, okay?"

Riley had only intended to suck or jerk off Max to make him cum, but Max wanted more and when he began putting his hands all over his friends new body, Riley couldn't resist either.  It actually felt amazing to get fucked as a girl and seeing as they had nearly half an hour to complete the challenge, Riley decided it was worth finding out how it felt to get fucked in the pussy.

"Oh shit Max, that feels really nice... I never knew you had such a big dick,"

"What are you talking about baby, you love my cock... this isn't the first time I fucked you?  Are you okay?"

"Oooooh, yeah, just hurry up and cum all over me will you, I errrr, I want it badly."

Riley breathed a sigh of relief as a few minutes later Max pulled out his dick and ejaculated all over him.  As the sticky cum washed over his belly, he lay back and felt the panic recede.  He had beaten the challenge.

As Max went to clean up, Riley waited - but nothing happened.  "Why aren't I changing back?" he whimpered nervously.  Suddenly his phone vibrated and another message came through.

"Well done slut, you completed the challenge.  As promised everything will now go back to normal for you.  This means that all your male memories will fade and you will believe you have always been a hot girl called Riley with an awesome life.  Enjoy."

"No, noooo, NOOOO!" groaned Riley as her head suddenly burned and it got hard to think.

"Ooooh, where am I?" giggled Riley a moment later as the burning receded and she smiled.  "Oh yeah, I just got fucked good by my boyfriend, mmmmh, that was nice."  Using a finger, she collected some cum and licked it clean. "Mmmmh, yummy.  Hey Max baby, bring some tissues in here will you. I need to clean up and then can we go to the Mall, I wanna buy some new clothes!"

For Riley the slut challenge was over - but her slut life was just beginning...
