Marla locks you up...momentarily

After the door closes, Marla looks back at you. You feel your hard on pressing against your underwear, and by the look on her face, you guess so does Marla.
She smiles, looking a bit nervous. "So...I hope this isnt to uncomfortable for you. Thanks for being my test rabbit."
Then she comes closer, her hand gliding down your stomach. "Now...lets get you undressed and ready."
And she pulls your underwear down. Your dick, already hard, jumps up and she grabs it with her hand. "Now why dont you lay down for me big boy." She whispers, and you do as she tells you. Your heart beats faster. Does this...exite you?

Moments later, you lay down on the slightly uncomfortable leather tray, and before you know it, Marla fixates your hands with the leather cuffs above your head.
Then she walks around you and fixates your ankles. Now you´re completely at her mercy, laying there, nude, and tied up.
Marla gets out of her dress again, and only wearing her underwear, she climbs on top of you.
Her knees to the left and right of your legs, she looks down on you, sitting right in front of your throbbing cock. A bit of precum has formed on the tip of it, which Marla notices. She bends down, and softly licks it up. "Exited, mmh?"
Then she begins to jerk you off. but she doesnt do it like usual, sensual and focussed. Her grip is hard, and her hand ist fast. Her other hand cups your balls while she jerks you off as fast as she can.
Her goal seems to be to make you cum as fast as she can, and you remember the real reason you´re laying here, confined:
"Athena told me its best to get you off before i ut you in chastity, because you´re less likely to try and get hard when you just came." She says. You already feel yourself approaching orgasm.
"You know what else Athena told me? She can record everything that happens in this room, so I´ll have a video of you tied up and naked, and in a couple minutes, in a cage for me...i like that idea, dont you?"
Fuck, that kind of did it for you. And after a minute or so more, you felt yourself reaching your edge, which Marla noticed. She continued for a couple seconds more, than she bowed her head down and teased only the back of the tip of your cock with your tongue, the most sensitive part.
You feel your orgasm, but not a lot. As Marla ruins your orgasm, you feel your body strain against its ties, trying to get more satisfaction, but you´re helpless. You watch, as marla holds your cock while cum slowly dribbles out the top.
She smiles. "There we go. Athena also told me most men in chastity rarely ever get real orgasms, so I wanted to emulate this. Now, lets lock you up."

She gets up, and grabs the silver cage from the table next to her. You watch as she grabs your softening cock, and slowly pushes it into the cage.
Inch for inch you vanish into your metal prison, until your dick is completely surrounded with cold metal. A silent click indicated Marla locking it shut.
She looks at you, smiling. "Oh my god...you look so much smaller." Her hand wraps around your cock, or at least the cage. "I bet you must be straining in there, right? Such a big cock in such a small cage. How does it feel?"

"Its tight", you say, feeling your heart beat of exitement. You hope Marla doesnt realize that this turns you on as much as it does. "It feels pretty unusual." You add.
Marla nods. "I bet it does. Do you think it feels less unusual the more you wear it? Do you think you´d get used to it over time?"

You dont answer, you dont know how. You feel your dick pressing against the silver bars of the cage.
"Well", Marla says, "I said I´d release you again, I didnt say when, and I think we can use that were here. How about you earn your release?"
"What do you have in mind?" You ask, carefully. Marla has the upper hand and you do not want to give her any bad ideas.

"Well I got you off already...its only fair if you do the same."
