Nuclear Locked, Part 2

[Part 1](https://www.reddit.com/r/ChastityStories/comments/165k2r0/nuclear_locked/)

Rachael was a materials expert, and a metallurgist savant. The kind that built her own forge for melting aluminum cans at home at the age of six.

By eleven she was asked not to participate in science fairs anymore. She was discouraging any competition.

By fourteen she had graduated high school, and got accepted to State Tech, where she literally lived in the bowels of Old Main. She got her first patent at 17, and by 21 had her Ph.D.

That was also the year she met David, and fell madly in love with him.

Racahel loved how smart he was, how he never dismissed her as a woman, and how he shared several of her kinks.

He had seen her browser history and saw she was into chastity, both for her and for him. So for her 22nd birthday he had bought her a chastity belt. She squealed, put it on, and handed him the key.

She then begged almost hourly to be let out. That it was so hot she just had to masturbate now!

But he knew she would enjoy it more if she just waited things out. He kept her in four days before surprising her with unlocking her.

And Rachael rode his brains out.

She then decided to make a chastity cage for David.

\-=-=-

Her bike had been stolen the first week at State Tech, and she had decided it would never happen again. She researched how to make a bike lock uncuttable, researched grapefruits and seashells, and came up with a truly uncuttable metal.

Nano ceramic balls, each coated with aluminum, distributed in an iron core. Cutting disks would strike the aluminum, melt it, and dull themselves with the ceramic spheres. The vibrations would end up fracturing the cutting disks.

Or, even scarier, the disks would powderize the aluminum, and the oxides in the ceramics would make the iron form Thermite. Let’s see a bike thief deal with 2500 C temperatures!

\-=-=-

Of course Rachael never half-assed anything. So she made sure she took well-fitting measurements of David’s cock, and within a week had a cage that could never be cut.

She drove David wild with it, Fellating him over it. He felt her tongue licking his cock skin between the bars of his new cage. And he struggled to get hard. Struggled to get off.

She had him right where she wanted him. And she was going to torture him the way he had tortured her.

That was a week ago.
