It was the university's reading week, and Sam had decided to use the time off to play at some self bondage. He had an entire week of no roommates in his pod residence, and hardly anyone at all on the floor of the whole building. Just him, one or two other students, and the RA, Mandy Darling, who had proven herself to be quite chill and flexible in allowing this bevy of first and second year students to have a proper university experience. So long as everyone made it back home safe, and comported themselves without imposing on others, Mandy was quite willing to stand aside and let fun happen.

Which was a rather relevant consideration at the moment.

Sam had stripped down to just his underwear for his self bondage session, and he had amassed quite a decent collection since leaving home earlier in the summer. Tight and thick leather cuffs graced his wrists and ankles, a thick leather waist belt was locked on, with thin straps hooking through the metal chastity device he had attached to ensure it was really inescapable. A decently comfortable ballgag silenced him, and the last bit was a nice leather collar that was part of the cuff set. A couple of chains between the cuffs connected them together and into a fairly snug hogtie. He could squirm and writhe around to his hearts content, and then unlock himself when he was ready. He even had headphones on so that he could listen to some teasing BDSM audio stories of dominant women capturing and toying with submissive men.

And yet, things had gone a little...pear shaped.

He still wasn't quite certain why, but the keys weren't working properly. Had he grabbed the wrong ones? He did have several, but he could have sworn they were the ones that had been tehtered to the locks he had used...but they weren't fitting into the blasted keyholes! He squirmed and writhed around on his bed, cursing himself for not having set up any kind of additional failsafe. Unless he got truly lucky, he was going to be stuck here for days without anyone being any the wiser. His roommates weren't due back until then...and...

KNOCK KNOCK

"Hey Sam," Mandy's voice was muffled from the hallway, she was clearly shouting to be heard through the door, "The others are planning on going out to a movie and then Finnigan's Catch for beers and dinner. Up for a social outing?"

Sam groaned, fighting through his embarrassment at being found like this, and gave a shout of relief and frustration into his gag.

"I don't...are you okay in there?" Mandy's voice hovered somewhere between amusement and concern, "Don't tell me one of these yahoos played some sort of...okay, gimme two distinct yells if you need help."

Sam did so, his face flushed crimson at the thought of his super hot RA finding him like this...but what choice did he have? He shouted again, two distinct blasts of his muffled voice, and felt relief and squirmy apprehension flow through him as Mandy opened the door of the residence pod.

"Sam?" Her voice carried now and she stepped more fully in, "If this is some prank you're trying to pull on me just wanna warn you that...oh..." Her voice stopped, and Sam closed his eyes with a moan as he squirmed on the bed. Mandy let out a small chuckle, "Now I see why you couldn't answer the door like a proper gentleman...someone has...intervened."

Sam moaned and struggled, trying to indicate that he wanted to be untied. Mandy strode over to the bed and plopped herself down. She was dressed to go out. Tight dark purple leather pants, a bluish black top made of some shiny, almost liquid material gave her a fetish look, her ample breasts enhanced by the look and displaying generous cleavage. Her purple-blue hair tumbled around her shoulders, giving her face an elegant and intimate framing. brown eyes twinkled out of her pale face, and she grinned down at him, one hand settling on his underwear covered rump.

"Hang on...I don't see a note. I don't see kidnappers tools..." Mandy adopted a deliberately shocked tone, "Why, Samuel, Samuel, Samuel, did you get into this terribly vulnerable position all by yourself?"

Sam bleated into the gag, squirming a little more and flushing bright, brilliant red. And then he really squealed when Mandy's hand slapped onto his ass in an unmistakable spank



SMACK.

"MMMMPGHH!!??"

"I was pretty sure you were into this sort of thing, but goodness me I actually thought you were a bit more of a dominant. Hidden away beneath that introverted exterior, you've no idea the number of young men who flower when they finally get a gal, or guy, of their own." Mandy's hand rubbed along his stinging ass cheek, and then dipped down along his thigh...and encountered the distinct hardness of his chastity cage, "Then again...most first or even fifth time self bondage fans don't go for a metal chastity cage...which seems to tell me that this isn't so much experimentation as...indulgence." She fairly crooned the last word, clambering up from her seat to settle on top of his back, flipping him over so that she could examine his cage. Which just so happened to put her leather covered ass and pussy directly overtop of Sam's blushing wide eyed face.

Which then somehow managed to go a deep burgundy as Mandy calmly tugged his underwear down and out of the way and flicked his caged cock.

"MMMNGGH!!" Sam bucked a little, and smacked his face right into her ass, and then let out a moan as Mandy responded by settling back, pressing her butt into his forehead, and placing his nose and gagged mouth...right...there...oh...oh God...

"Mmmmngh, I mean I'm certainly not going to stop you..." Mandy teased and then giggled, "Well, actually, I am going to stop you. I'd hardly be a good domme, a good friendly captor, if I let you do anything you wanted. Now, lets see." Still seated upon his face, Mandy leaned over and snatched the keys from where they had fallen on the bed, "I can see why you're stuck. You've gotten the keys all mixed up, I bet you didn't even realize you were using the chastity key on your wrists or legs...what with you being..." she reached down and gripped his full balls, making Sam's eyes bug out and a loud moan explode from beneath her. She wiggled herself more firmly atop his face with another giggle, "Since you clearly aren't responsible enough to practice self bondage alone, I'll be keeping these keys."

Sam gurgled, trying to shake his head, but doing nothing save send pleasant vibrations up Mandy's thighs.

Mandy just giggled and continued to flex her thighs and wiggle her butt, encouraging him to keep squirming and moaning as she pulled out her phone and began texting. The first went to Eric, Dan, Liz, and Yancy, letting them know to go on without her. Sam was in need of some RA assistance, and the four of them could go enjoy themselves. The second text was to her good friend Laurel, letting her know that there was no need for the two of them to go out hunting after dinner, as they had been planning to do. She'd stumbled into a new playmate all on her own. She did tell Laurel to bring their usual toys, as well as a large suitcase. It wouldn't do for anyone to see the two of them moving Sam in between rooms...and her own room was much better set up, and much more private, for the keeping and training of a cute university boy into an aching, horny, and obedient little slave.

She leaned down, the texts sent, and delivered several playful but still firm slaps to the insides of Sam's thighs, making him buck and wiggle, moaning and gurgling beneath her.

"Now then, darling Sam. Since you're in chastity, you can forget about cumming. Normally I'd let a subbie enjoy themselves with an orgasm, but chastity boys like you get just as much enjoyment from not cumming...and I'd never dream of denying you that pleasure." Sam shook his head frantically, but Mandy just clamped her thighs more firmly around his head, and began grinding herself against his gagged lips and his nose. God she was already starting to get wet.

"The next thing is...this is going to be your reading week now. No release from this bondage. No freedom from my control. Once we've had our fun here, you'll be coming back to my space. My little RA apartment has been nicely transformed into just the sort of dungeon that you'll love...and I've got a perfect rubber catsuit that you are going to look incredible in. My little Sam prisoner, all gimped up and ready to be toyed with all week long..."

Sam gurgled, his cock straining in its cage, his relief at being found now twisted with arousal, fear, desire, and aching need. His mind was spinning away out of control as Mandy stroked his caged cock, grinding against his face, and continued to regale him with what the future held for him.

A future that would see him spend the full week as her bound, submissive gimp slave, his only duty to pleasure her and her friend...and submit to their intensive training...

There would be no relief whatsoever...
