The Developer already told you they aren't adding any more women that will have content in relation to Lilith's contract.
The whole plot of the game is to have the main character breed 30 mortal women - so putting 2 and 2 together, you should be able to deduce that at least 30 women are going to get impregnated by the main character.
See a previous post by the developer (found by searching the thread for Leslie bred)
The other 2 might not... the other 2 might... perhaps it's something the developer wants to keep as an option or a secret or the like. But note that as soon as the main character has bred 30 mortal women --- the contract is fulfilled --- so the other 2, if they are impregnated, might be epilogue stuff.
The same goes for Leslie - perhaps saying such in the thread isn't something the developer wants to fully disclose... yet... no matter the answer. But the developer has made it known many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many, many times that Leslie is his favorite character and we all know she gets at least a little content in ever single release - not just in the family updates.
