The irony is, he built the machine for her. A fucking machine to put his kinky, submissive wife onto.

Only when it was nearly finished, they discovered the impact of caging his cock. It took only a few months before their ritual became established. Tied down, she’d take the tight little cage off, the relentless dildo penetrating his ass, massaging his prostate, and with a little help he’d empty himself into the condom, which she then emptied into his mouth, not once, but as many times he she wanted until there was nothing left to squirt.

Then locked back up, until she felt he was desperate enough again.

What he didn’t know, is she’d decided to invite other chastity wives to the next session. Selling tickets, and the machines, would mean she could give up her job and just focus on this in future.
