"It's nothing huge," my best friend remarked, settling back onto my dorm room bed and arching an eyebrow at me, "Just one tiny favour. One thing, that's all I ask."

I sighed and sat on the bed next to her, giving her a good natured glower. Maggie and I had grown up together, spending nearly every moment of every day we had playing and adventuring around. Yet the last couple years of high school her family had moved away, and so it was only this past pair of months at university that I had reconnected with her...and her mischevious sense of humour and playful approach to life had seemingly intensified when she had been away. She was a brunette, keeping her hair style and slightly under shoulder length, with a grin and a daring twinkle in her eyes that were never far away...especially when wheedling me to do something for her.

"Alright. Alright!" I put my hands up in mock surrender, "I give. You've been pestering me for the last two weeks about this mysterious favour." I affected a glare but it washed right off her as she suddenly perked up on the bed and leaned forward, anticipation quivering. I shook my head, "Seriously, if its such a tiny eensy weensy favour why is it so..."

"I want your chastity keys."

I did a genuine double take, a sudden pit yawning wide in my stomach. I couldn't help myself, one hand on autopilot covered my crotch where, I was suddenly sinkingly certain, the faint outline of my cage could be discerned.

"You...you..."

"Oh c'mon you don't need to do that." Maggie flicked my hand away with a grin, "I spotted it at the start of the month. Doing Locktober huh? Do you actually have a keyholder?"

I blushed bright red, my voice reduced to mumbling, "I...I don't, not...not really I'm...you..."

"What I figured," Maggie shrugged, still grinning, and scooted herself closer, eyes now locked onto mine with the burning intensity that I had never in a million years been able to resist, "You don't have to be embarrassed. I've been dipping my toes in the scene too...and this university and town are just rife with fun loving people who are into this...and I figured...if you weren't already secured by someone...well, the life shattering implications of being locked in chastity would be less huge if your key was held by your best friend."

I stared at her, mouth open, and her grin widened before she leaned in and kissed me. I sputtered, eyes wide as she pulled away after three glorious seconds, "I...you...we just...I..."

"If you can't string a sentence together properly I can always gag you..." Maggie teased. Before I could respond to that she scooted forward even further, clamping a hand over my mouth, "Nope, no more responding. I get to talk without you squeaking and running. I want to hold you key. I want to help you experience submission. And if I'm being totally honest...I want you." Maggie's eyes were huge luminous pools, sucking in what tiny elements of control I might have still possessed, "I figured it out when I was away at that stupid private high school, and its why I accepted this university's offer instead. I've known you for my whole life, and you are the sweetest, funniest guy. I think its high time we dive right in...and I can't think of a better way to start our new dynamic...than for you to be my locked, squirming, adorable little chastity submissive...and me to be your wise, alluring, controlling keyholder."

My eyes had to be as wide as dinner plates as she kept one hand gagging me, the other held out in front of me, "So your keys, if you please, buster. And don't worry, I don't believe in permanent lockups. After all, I'll be interested in playing with my new toy too. But as of right now...you and your cock, are mine."
