I don't know if it's been brought up lately but I find the fact the PC cant use the Milking room in the nursery very annoying to me.
In fact, it could be a little mini-quest or upgrade tree, Install a New Texas milker, have a milk tank for storage, then have options to have the one Sera uses to send its excess to the nursery to feed her kids and to install one on the ship so when you land on Tarkus it transfers to the nursery and/or as a beverage on the ship Reaha could also contribute. the other lovers on the ship could tease the PC about it via blurbs or into's when interacting with them and Yammi.
Second:
A lactoBlaster like from the COC mod would also be neat have, I imagine it to be low or no damage and go off milk tease but do multiple per turn. It would fit in well on Dhaal or New Texas, say it was a novelty item on New Texas for keg girls or as a portable auto-milker but was modified for use as a weapon on Dhaal.
Have the original take up an accessories slot but have the modified one be a heavy weapon or need a harness(leather or magnetic) to be worn.
That way original would just up tease damage but multiply milk tease whereas the modified one would be both that and real damage and milk tease at the same time. If used for more than X times in combat it turns on the pumps to refill and increases lust. If the PC is over a certain limit for milk production or has enough built up a high-pressure mode that would empty the breasts and built-in tank for massive damage/lust but then be inoperative for the rest of the fight or for a few turns if the PC has the right perks like Mega-Milk.
