The thing I most want to see is a lizard couple added to the vore center. If you let out three satisfied lizards in a row, their recommendation finds its way to a lizard couple. From there, you can pick an MM, MF, or FF couple. The animation will involve both climbing into your balls. Cost goes up from $15k for three days to $25k for three days. They get frisky in there and cause a lust penalty of 5 per round (so +25 lust per day). If you screw up and churn them, the job won't show up again that month. If you successfully release them, the job will continue to be available.
