"Oh no, silly, it's much simpler. It's on an 'in-perpetuity basis' which means it goes until you decide to stop it, for up to a year, and the best part is that can you cum as often as you want, however if you do, it may lower your payout significantly, since it has to be filtered.
"All you have to do today is sign the contract, take the, um...special 'multivitamin,' and get fitted for a new, special device. The new 'cage' actually allows full movement, since it's like a jelly compound and molds to the skin. In fact, the more you try to cum the better, since that builds up the fluid, and if you do cum, you still will get paid a little bit."
Lily of course knew that the new chastity device absolutely prevented any possible ejaculation since there were already 4,000 cases of male subjects unable to get any sort of release, but of course she didn't need to share that. She just needed you to sign.
"Well, shit, this sounds amazing, Lily. I could really use the money, and I need to cum so badly I could burst. Okay, just let me read this a little bit to make sure."
Lily grinned. "Oh, that's great! And today, we'll make sure you release any buildup before we fit the new device. So you'll get to cum before you leave here!" Lily adopts a conspiratorial tone. "*I* think I'm your case manager for that, so I'll be the one who will help you to cum, too, unless you'd prefer one of the other girls?"
You couldn't believe it. Your dream girl was going to jerk you off!. You couldn't wait. Lily continues:
"Honestly, I'm so glad you completed this first study. I've always thought you were kinda hot. And all the money we-- you'll make! I'm so happy for. This is definitely a big step up."
